    Exploring the usability of a videophone mock-up for persons with dementia and their significant others2014In: BMC Geriatrics, ISSN 1471-2318, E-ISSN 1471-2318, Vol. 14, p. 49-Article in journal (Refereed)
    Abstract [en]

    Background: Persons with dementia might have considerable difficulties in using an ordinary telephone. Being able to use the telephone can be very important in order to maintain their social network, getting stimulation and for reaching help when needed. Therefore, persons with dementia might need an easy-to-use videophone to prevent social isolation and to feel safe and independent. This study reports the evaluation of the usability of a touch-screen videophone mock-up for persons with dementia and their significant others. Methods: Four persons with dementia and their significant others tested the videophone mock-up at a living laboratory. In order to gain knowledge of the participants' with dementia ability to use their own computers and telephones, interviews and observations were conducted. Results: Overall, the participants had a very positive attitude towards the videophone. The participants with dementia perceived that it was useful, enjoyable and easy to use, although they initially had difficulties in understanding how to handle some functions, thus indicating that the design needs to be further developed to be more intuitive. Conclusions: The findings suggest that the videophone has the potential to enable telephone calls without assistance and add quality in communication.

    First steps in designing a videophone for people with dementia: Identification of users' potentials and the requirements of communication technology2012In: Disability and Rehabilitation: Assistive Technology, ISSN 1748-3107, E-ISSN 1748-3115, Vol. sept, no 5, p. 356-363Article in journal (Refereed)
    Abstract [en]

    Purpose: To identify, based on the literature, people with dementia´s potentials to manage an easy-to-use videophone, and to develop a videophone requirement specification for people with dementia.

    Method:The study is based on the Inclusive Design method, utilising the first two of four phases. Content analyses of literature reviews were used to identify users´potentials for managing a videophone and to gather recommendations regarding communication technology design for the target group. Existing videophones in Sweden were examined regarding potentia fit to users with dementia.Findings: This led to detailed identification of cognitive, physical and psychosocial challenges that people with dementia will probably have when using an ordinary telephone or videophone. A requirement specification for videophone design to fit users with dementia was formulated, with the seven principles of Universal Design as a framework.Conclusions: The requirement specification presented here is aimed at designing a videophone but might also facilitate design of other products for people with dementia, particularly in the field of communication technology. Based on this, further work will focus on developing a design concept and a prototype to be empirically tested by people with dementia and their significant others, i.e. the final two design process phases.

    Kognitiva köket - framtidens kök2010Report (Other academic)
    Abstract [sv]

    Äldre personer som har en demenssjukdom eller andra medicinska diagnoser som kan leda till kognitiva problem och som bor i egna hem är en växande grupp. Samtidigt så förväntas alla oavsett funktionsnedsättning kunna hantera matlagning och andra köksrelaterade aktiviteter på egen hand.

    Personer med kognitiva problem, och personer som arbetar med denna grupp definierar problem relaterade till matlagning och att hålla ordning i köket som några av de viktigaste att lösa (Wherton and Monk 2008). Att kunna utföra köksrelaterade aktiviteter betraktas som något som höjer livskvaliteten. Trots det växande behovet av att kunna skapa köksmiljöer och köksprodukter, både generellt och med individuella anpassningar, finns det i dag ingen samlad kunskap om hur sådana miljöer och produkter bäst kan utformas.

    I det här projektet ses köket som en plats där flera dimensioner av livet pågår. Förutom matlagning och förvaring av mat så är köket även en plats för socialt umgänge, och utgör vardagens nav. Kökets roll i hemmet är alltså central. Projektet utgår från att det är möjligt att skapa inkluderande köksmiljöer som tar hänsyn till personer med nedsatt kognition, men som samtidigt förenklar för alla.

    Modern design av kök handlar idag mycket om eleganta ytor och dolda, och därmed svårdefinierade, funktioner vilket skapar problem för personer med kognitiva funktionsnedsättningar. Dessa problem måste lyftas fram och diskuteras för att kunna utforma framtida inkluderande köksmiljöer. Syftet med projektet är att, i dialog med intressenter och experter inom området, sammanställa och generera kunskap om hur kök och köksprodukter kan designas för att underlätta för äldre människor med kognitiva nedsättningar att kunna använda sina kök utan problem.

    Being a pedestrian with dementia: A qualitative study using photo documentation and focus group interviews2016In: Dementia, ISSN 1471-3012, E-ISSN 1741-2684, Vol. 15, no 5, p. 1124-1140Article in journal (Refereed)
    Abstract [en]

    The aim of the study was to identify problematic situations in using zebra crossings. They were identified from photo documentations comprising film sequences and the perspectives of people with dementia. The aim was also to identify how they would understand, interpret and act in these problematic situations based on their previous experiences and linked to the film sequences. A qualitative grounded theory approach was used. Film sequences from five zebra crossings were analysed. The same film sequences were used as triggers in two focus group interviews with persons with dementia. Individual interviews with three informants were also performed. The core category, the hazard of meeting unfolding problematic traffic situations when only one layer at a time can be kept in focus, showed how a problematic situation as a whole consisted of different layers of problematic situations. The first category, adding layers of problematic traffic situations to each other, was characterized by the informants' creation of a problematic situation as a whole. The different layers were described in the subcategories of layout of streets and zebra crossings, weather conditions, vehicles and crowding of pedestrians. The second category, actions used to meet different layers of problematic traffic situations, was characterized by avoiding problematic situations, using traffic lights as reminders and security precautions, following the flow at the zebra crossing and being cautious pedestrians. In conclusion, as community-dwelling people with dementia commonly are pedestrians, it is important that health care professionals and caregivers take their experiences and management of problematic traffic situations into account when providing support.

    Accessibility in public space as perceived by people with Alzheimer´s disease2011In: Dementia, ISSN 1471-3012, E-ISSN 1741-2684, no aug 11Article in journal (Refereed)
    Abstract [en]

    Most people with dementia remain living at home as long as possible after being diagnosed, and hence their lives also include activities in the public space. The aim of this study was to illuminate experiences of accessibility in public space in people with Alzheimer’s disease. A qualitative grounded theory approach with repeated in-depth interviews was used. The core category, accessibility as a constantly changing experience, was characterized by changes in the relationship between informants and public space. Changes in the relationship took place in activities and use of place and related to familiarity and comfort, individual motives and interests, and planning and protecting. Other changes occurred in places and problematic situations related to everyday technologies, crowded places with high tempo and noise, and change of landmarks. These changes reduced feelings of accessibility and increased difficulties in carrying out activities in public space. These findings may be helpful when providing support, and supporting community living.

    Contention-Based Wireless Sensor Networks: A case study for ambient assisted living2010In: Active Ageing, Smart Solutions, New Markets, 2010Conference paper (Refereed)
    Abstract [en]

    Wireless personal area networks have emerged as an important communication infrastructure in areas such as at-home healthcare and home automation, independent living and assistive technology. Initiatives towards interoperability and standardization are taken by several players. Zigbee Alliance has launched a profile for “Zigbee wireless sensor applications for health, wellness and fitness” [1]. The Continua Health Alliance promotes “an interoperable personal healthcare ecosystem”. They have published “design guidelines for the telehealth ecosystem” including the interface to personal area network health devices and electronic health record devices ([2], [3]). These examples show that wireless personal area networks, including body sensor networks, are becoming more mature and are considered to be a realistic alternative as communication infrastructure for demanding services. However, to transmit vital sign parameters from ECGs, pulse-oximeters, EEGs etc in wireless networks is also a challenge, especially if multiple sensors compete for access. Contention-based access networks offer simplicity and utilization advantages, but the drawback is unpredictable performance due to loss of transmitted packets.

    We have used the SHIMMER wireless sensor platform developed at Intel [4] in the living lab at the Centre for Health and Building at KTH in a case study to identify and evaluate performance problems. The full-scale living lab consists of two apartments especially equipped with modern technique for healthcare at home and assisted living.

    Our paper focuses on continuous monitoring of the heart activity using a wireless ECG based on the wireless personal area network (WPAN) standard IEEE 802.15.4. Results from performance tests in the living lab will be presented e.g. influence of equipment such as micro wave ovens. Since contention-based wireless access has no guarantees for the quality of the delivered service it is interesting to determine to what extent the received ECG signal is sensitive to loss of information. We have recorded ECG signals as well as emulated packet loss in existing ECG records from official databases. The result of two cardiologists´ assessment of ECGs with different loss ratio levels and patterns will be reported in the paper. One interesting conclusion is that a diagnosis is fully possible for ECGs with packet loss ratio up to at least 5%. This project is part of research at the School of Technology and Health at KTH.

    A walker used as a lifting device2014In: Disability and Rehabilitation: Assistive Technology, ISSN 1748-3107, E-ISSN 1748-3115, Vol. 9, no 3, p. 264-269Article in journal (Refereed)
    Abstract [en]

    Purpose: To develop assistive technology that would help an older person to arise from a kneeling position to a standing one. Methods: Developing a prototype, based on an inclusive design and then testing the prototype to verify the approach. The prototype was subsequently tested by a panel of 20 elderly users. These tests were observed and filmed. Participants' experiences of being lifted with the elevation seat were registered with the VIDAR ergonomic assessment system. Result: None of the 20 participants used a walker at that time. In response to a question of whether, assuming they might have to use a walker in the future, they thought that a walker with an elevating seat would be helpful, 18 said that it would. Two of the participants did not believe that they would ever have to use a walker. Conclusion: A simple assistive technology such as a walker equipped with an elevating seat would in many of these cases simplify matters and reduce the distress of people who fall often. In addition, such a device can allow people who fall often to live in their homes longer. For caregivers dealing frequently with people who fall, this assistive device can contribute to decreasing occupational injuries.

    Adoption of Ergonomic Innovations in the Construction IndustryIn: Ergonomics in design, ISSN 1064-8046, E-ISSN 2169-5083Article in journal (Refereed)
    Abstract [en]

    AbstractThe construction industry is overrepresented compared to other industries in terms of work-related injury problems and, in particular, with respect to musculoskeletal disorders. One reason for this might be that the industry is organized around projects which lead to a short-time behavior and does not stimulate innovations that will reduce injuries in the future. In this paper we present the results from a survey performed in Sweden among 50 floor laying companies. The results indicate that short-term income revenues override the long-term risks of injuries and employees having to leave the profession.

One reason might be that the industry is organized around projects that lead to short-term benefits and does not stimulate innovations that will reduce injuries in the future. In this article, we present the findings from a survey performed in Sweden among 50 floor-laying companies. The results indicate that short-term income revenues override concerns over the long-term risks of injuries and employees leaving the profession as a result of those injuries.

    PYCIPEDIA: Supporting local and remote collaboration between social workers2019In: Proceedings of the ACM Conference on Computer Supported Cooperative Work, CSCW, Association for Computing Machinery , 2019, p. 195-199Conference paper (Refereed)
    Abstract [en]

    PYCIPEDIA is a web-based collaborative tool for social workers that support parents with intellectual disabilities taking care of their small children. These particular social workers have been certified in providing parenting-skills training and support for parents with intellectual disabilities or with learning difficulties. As only a relatively small number of social workers are certified in providing the relevant support, there may be few colleagues to discuss with and learn from, even in larger municipalities with many social workers. To support social workers in providing the best possible support, the web-based collaborative tool PYCIPEDIA has been co-designed with social workers from two Swedish municipalities. The tool allows social workers to log in, and independent from what municipality they work in, create, browse, edit and share material (e.g. text, images and video) that can support the parents. They can discuss cases, rate online material, and access a forum.

    On Challenges Designing the Home as a Place for Care2014In: Pervasive Health: State-of-the-art and Beyond / [ed] Holzinger, A., et al., Springer Netherlands, 2014, p. 19-45Chapter in book (Refereed)
    Abstract [en]

    Traditionally, there has been much attention on workplace studies and design for work within the HCI (Human Computer Interaction) and CSCW (Computer Supported Cooperative Work) communities. Those communities have recently shown an increasing interest in healthcare and especially non-professional care settings such as patients’ private homes. When healthcare is moved from clinical settings to private homes, more attention is put on the care receiver, his/her everyday life and private home. In contrast with the hospital, the home however is not designed as a place for care. Moving healthcare activities, including treatment of severe diseases to private homes and other non-clinical settings (e.g. the patient’s workplace or vacation resorts) not prepared for these care activities may have severe consequences. In fact, the relocation of care may challenge, on different levels, the patients, their caregivers and society at large. This chapter presents and discusses seven challenges that the authors argue are important to consider when designing for holistic and sustainable home-based healthcare. Examples of these challenges are: Societal concerns, Complexity of care providers, Heterogeneity of care providers and Installation and maintenance. These challenges include law and legislation related aspects, environmental issues and the feasibility of large-scale deployment of home-care designs. The challenges discussed in this chapter have not been satisfactorily taken into account by the existing homecare designs and HCI research. Our chapter suggests that designers and HCI practitioners must be aware of, and reflect upon how these challenges can affect the value, feasibility and a wider implementation of their homecare designs.

    Work Postures When Assisting People at the Toilet2015In: Ergonomics in design, ISSN 1064-8046, E-ISSN 2169-5083, Vol. 23, no 2, p. 16-22Article in journal (Other academic)
    Abstract [en]

    The aim was to analyze the home care workers’ movement patterns and postures of their backs, relating them to risks while helping an ambulatory care recipient to/from the toilet in a homelike environment. We found severe risks of unpredictable movements with exposed postures could explain many injuries. Because of high risk injuries, we suggest decreasing the time when the care recipient stands and the home care worker helps with clothing and personal hygiene. Another suggestion to decrease high risk is development of support in front of the recipient to prevent her/him falling forward.

    Network-Centric Business Models for Health, Social Care and Wellbeing Solutions in the Internet of ThingsManuscript (preprint) (Other academic)
    Abstract [en]

    In this multiple case study we analyze solutions based on connected devices in the context of health, social care and wellbeing. Based on the consideration that a solution is a combination of services and products, we build on the notion that business models can be studied at a firm- and a network-level. These two levels are used to motivate the reasons why solutions emerging at the intersection of the healthcare and the ICT industries benefit from collaboration among different actors. We conclude that the firm- and the network-level development of business models provide alignment in the business network and are useful to establish the relation that technological component have with overall solutions. Our findings suggest that some component bring novelty in the final offer with affecting the ongoing operation, while other component aim at improving the internal working processes, with minimal effects on the final offer to end users. We discuss the benefits of a network-level perspective for each case.

    ACTION - ett anhörigstöd: Testat i Linköpings kommun under 2 år2009Report (Other academic)
    Abstract [sv]

    Behovet av ljus ökar med stigande ålder och bristande belysning kan vara en orsak till att särskilt äldre människor snubblar och faller med skador som följd. Linköpings kommun har genomfört en belysningsstudie bland dagens äldre i Linköping vars syfte varit att få kunskap om vilka behov av åtgärder kring belysning som finns hos de äldre. Studien har finansierats inom ramen för programmet Teknik för äldre som administreras av Hjälpmedelsinstitutet på uppdrag av Socialdepartementet.

    Ögat förändras under åldrandeprocessen och redan i 40-års åldern kan man märka hur synen blivit sämre än den var vid yngre år. En person i 40-års åldern behöver dubbelt så mycket ljus som en person i 20-års åldern för att kunna läsa eller skriva. För äldre kan också ljus i form av ljusterapi ha en mycket god effekt på sömn och välbefinnande. Frågan om belysning är därför starkt relaterad till ålder. Marknaden för belysning utvecklas idag i rask takt. Ny teknik att skapa ljus i form av lågenergilampor eller lysdioder (LED) bidrar till denna utveckling.

    Rapporten presenterar hur de intervjuades belysningsförhållanden ser ut idag och vilka problem eller önskemål de intervjuade upplever kring belysning i bostaden.

    Men belysningen i äldres hem har inte bara betydelse för deras egen hälsa och välmående. I takt med att allt fler får vård och omvårdnad i sina bostäder blir bostaden också en arbetsplats för dem som ger vården. Det blir en balansgång mellan att undvika att bostaden utrustas och upplevs som en vårdplats, och att ge dem som vårdar den äldre i bostaden goda arbetsvillkor.

    Resultatet av intervjuerna som gjordes både som strukturerade intervjuer och som djupintervjuer samt med okulär besiktning av bostäderna, visar att de intervjuade oftast har alldeles för svag belysning. Särskilt visar det sig i sådana utrymmen där risken för fallskador är störst. I hallen och i vardagsrummet är belysningen oftast mycket bristfällig. I hallen för att det inte finns så många möjligheter att installera ljus eftersom det traditionellt finns ett takuttag där det oftast sitter en plafond med alldeles för svag glödlampa. På väggarna finns oftast bara ett eluttag som används till spegelbelysning eller dekorativ belysning.

    Ett annat problem utgörs av svårigheterna att byta glödlampor i taket. De äldre vågar inte ställa sig på pallar eller stegar för att byta glödlampor, eftersom de ofta har problem med balansen. Likaså är sladdar på golvet ett återkommande problem.

    Digitala lås2010Report (Other academic)
    Abstract [sv]

    Sammanfattning

    Användningen av elektroniska lås har på allvar börjat bli en fråga som fler och fler, både fastighets- och vårdföretag, tar upp. De risker som är förknippade med att hantera andras nycklar vill både vårdgivare och bostadsinnehavare minimera. Hjälpmedelsinstitutet har inom ramen för regeringsuppdraget Teknik för äldre finansierat denna test av elektroniska lås som genomförts i det lab som Centrum för Hälsa och Byggande (CHB) på KTH i Handen har satt upp. Syftet med testet har varit att se hur de elektroniska lås som finns på den svenska marknaden idag fungerar. Och hur de motsvarar krav som kan ställas inom äldreomsorg och vård i hemmet.

    I den här testen har fyra lås från olika tillverkare testats medan fem har identifierats. Det femte kommer att testas inom kort i CHBs lab där för övrigt planen är att alla nya elektroniska lås som kommer ut på marknaden fortlöpande testas och publiceras på CHBs hemsida (www.chb.kth.se).

    Resultaten visar att det finns i huvudsak två huvudkategorier av elektroniska lås, eller lås med digitala nycklar. Den ena innebär ett fast installerat lås som är anslutet till någon form av box i bostaden och som kan kommunicera med en central via Internet. Det är en lösning som också erbjuder en hel del tilläggstjänster som kan underlätta kvarboende för den som är äldre. Den andra lösningen är mobil i det avseendet att låset kan installeras och nedmonteras för att flyttas till en annan vårdkund mycket snabbt. Det är ett lås som inte själv är kopplat till Internet eller annat nätverk, utan kommunikationen med låset sker via den digitala nyckeln eller genom att man själv går till låset och hämtar information om det behövs.

    Det är viktigt att påpeka att Datainspektionen har beskrivit vilka krav som ställs på ett digitalt lås som används hos en boende. Bland annat måste den boende vara informerad om låset och loggar får inte sparas hur länge som helst.

    Endast en låstillverkare har idag redovisat att det finns möjlighet att ansluta deras lås till ett administrativt system som kan användas av vårdgivaren, men det finns en beredskap att ta fram det gränssnitt som är nödvändigt för att detta ska vara möjligt, hos de andra tillverkarna. Det krävs dock att det finns en efterfrågan av detta.

    Internet of Things and Health Care at Home2011Conference paper (Refereed)
    Abstract [en]

    In the industrialized world the demographic development is threatening the societal quality of service. When over 20 to 25 % of the population is more than 65 years old and retired, the productive part of the population has to carry a heavy burden. In Sweden the number of beds in nursing homes and hospitals are reduced. The home becomes the place for both rehabilitation and advanced medical care. This raises a lot of question about how to make this safe, efficient and reliable. It is obvious that to some extent technology must be part of this new caring situation. Without the IoT-technology this will be expensive and complicated.

    In our lab at the Centre for Health and Building (CHB) at the Royal Institute of Technology in Stockholm, Sweden, we test and develop new technology aiming for support and care in peoples home. The lab consists of two self-contained apartments where a real life situation is a fundamental condition for the tests. We can see in a recent project (EU funded MonAMI) that with today’s technology where the assistive system is set up with its local, normally wireless, network, it is a tedious work to install such a system. Much has to be done locally in the apartment and if anything goes wrong a technician has to come and put things in order. Remote administration is possible but it is depending on the whole system to work proper and it is not possible to administrate a single node remotely.

    In a field trial we are connecting 30 apartments, but already at this small number it takes to much time to visit each apartment to configure the nodes and actuators. Even with few services a lot of nodes and actuators must be used.  This makes it a very expensive installation.

    This presentation will discuss the possibilities that come with an Ambient Assisted Living-system (AAL) based on IoT, and the problems that will occur without IoT. In our lab we are setting up a more flexible IPv6 based system, where all the nodes will have an IP address of its own. The aim is to see how an Ambient Assisted Living-system would be built when it is possible to access and configure all the nodes remotely.

    We think it will reduce the overall cost and in this way make AAL an important part of care in the home.

    IT i hemmet för vård och omsorg2006Report (Other academic)
    Abstract [sv]

    Människor lever allt längre och är aktiva upp i hög ålder. För kommunernas del sker en anpassning som betyder en omfördelning av resurser från ”unga” gamla till ”äldre” gamla. Färre får omsorg i särskilt boende och fler i det ordinära boendet i form av hemtjänst och annan avlastning. De äldre som ändå flyttar till särskilt boende är i så stort behov av omsorg att de inte längre kan bo kvar hemma.

    Utvecklingen inom vården gör att bostaden blir platsen för allt mer av vård och omsorg – exempelvis skickas människor hem allt tidigare efter operationer vilket betyder att eftervården förläggs till den egna bostaden. När bostaden blir så central för vård och omsorg finns det också anledning att undersöka hur fastighetsförvaltningen utvecklas för att se om dess utvecklingslinje möter vårdens eller kanske divergerar. En stor del av de äldre drabbas av kognitiva funktionsnedsättningar till följd av sjukdomar eller som en följd av åldrandet.

    Personer med kognitiva funktionsnedsättningar har ofta svårigheter att minnas, orientera sig i tid och rum samt försämrad problemlösningsförmåga. Det kan leda till stora problem för brukaren och ställer stora krav på omgivningen. Samtidigt är strävan att klara sig själv en av de starkaste drivkrafterna för alla människor. Utformat och använt på rätt sätt kan tekniskt stöd vara ett bra komplement eller till och med möjliggöra ett självständigt boende för många personer som i dag är i behov av hjälp från utomstående[1].

    Minnesstöd och orienteringshjälpmedel är därför ett område där tekniken kan bidra på ett naturligt sätt utan att ersätta mänskliga kontakter. Istället kan det skapa självständighet och ökad självsäkerhet för den som drabbats av kognitiva problem. Andra områden där tekniken kan bidra är kring säkerhet och trygghet.

    Omsorg och vård i bostaden: krav på infrastruktur nu och i framtiden2008Report (Other academic)
    Abstract [sv]

    Det finns behov av att kunna bedöma vilka krav framtida omsorg och vård kan komma att ställa på bostadens infrastruktur. Intresseorganisationer som SABO och Fastighetsägareförbundet tillsammans med aktörer inom byggindustrin är just nu i full färd med att ta fram rekommendationer för hur de så kallade hemmanäten för bostäder bör se ut. Den här rapporten är ett bidrag till underlaget för det arbetet utifrån några samhällstjänster.

    Trender kring omsorg och vård i hemmet har här studerats i ett antal nationella rapporter och internationella artiklar. Resultatet visar att både omsorgsverksamheten och vården arbetar med att ta fram system som ska göra arbetet i mobila team smidigare och enklare. Det är främst administrativa system kring journaler och processer som man försöker göra tillgängliga både över ansvarsgränserna landsting – kommun, men även i mobila system som team kan ha med sig överallt. Bild- eller videoöverföring från en bostad till en centralt placerad expert för råd och anvisningar är ett sådant exempel i framkanten på utvecklingen. Likaså icke-invasiva mätsystem i kläder som underlättar för patientens egenvård är ett annat. Vården tenderar att utveckla system som är oberoende av bostadens både el- och telefonnät. Istället baseras de på mobiltelefoni och batterisäkerhet. Det som kommer att ställa krav på bostädernas infrastruktur är lokala nätverk med sensorer och signaler för att skapa varnings- och påminnelsesystem hos den som behöver ett minnesstöd till exempel. Det vill säga sådana system som omsorgen arbetar med för att förlänga och underlätta äldres kvarboende i den egna bostaden. Sådana nätverk kan mycket väl vara samutnyttjade med fastighetens eget behov av telemetrisystem för mätning av energiförbrukning och för att eventuellt erbjuda andra bekvämlighetstjänster till den boende. En annan typ av tjänst som troligen kommer att växa är kommunikation via bild. Det förekommer både inom vården och inom omsorg eller anhörigvård. Kravet på tillräcklig bandbredd på framtidens IPTV kommer därmed att vara stort.

    The result from a two-year case study of an information and communication technology support system for family caregivers2013In: Disability and Rehabilitation: Assistive Technology, ISSN 1748-3107, E-ISSN 1748-3115Article in journal (Refereed)
    Abstract [en]

    AbstractPurpose: The aim was to better understand how information and communication technology(ICT) can provide support to elderly family caregivers caring for significant others suffering from dementia or stroke. Method: Ten households equipped with an ICT system, with a family caregiver and a spouse diagnosed with dementia or stroke, were followed and observed in a two-year case study. The family caregivers had regular meetings in groups organised by the municipal care of the elderly. Data from observations, semi-structured interviews, user data from the ICT system and data about the support provided by the municipality has been used to validate the findings. Results: The family caregivers socialised with users in the group as long as the users were stayed in the group. Meetings in the group were an important opportunity for exchanging experiences and to easing one’’s mind. The ICT system did not reduce the municipality’’s level of services to the participating families. The information built into the system has to be constantly updated to be of interest. Conclusions: An ICT support must be provided in a context of personal meetings and with a formal caregiver backing. This will empower informal or family caregivers. Such support must give the user the possibility to communicate and get access to the Internet.

    The Cognitive Kitchen: Key principles and suggestions for design that includes older adults with cognitive impairments as kitchen users2011In: Technology and Disability, ISSN 1055-4181, no 23, p. 29-40Article in journal (Refereed)
    Abstract [en]

    The aim of this study was to generate new knowledge as basis for the design of kitchens and kitchen products that support ageing persons with cognitive impairments in kitchen activities within the cultural context of Swedish contemporary middle class society. Existing knowledge on the issue was collected through a review of the literature on previous research and through focus group discussions with those identified as experts in the area, including persons with cognitive impairments and their kin, occupational therapists and researchers. The analysis of the existing knowledge identified three important domains of kitchenrelated activities – 1) storing, cooking and eating food, 2) socialising activities, 3) organising everyday life for oneself and the family – and four principles for design of a cognitive kitchen – a) Safety; b) Support for order and structure, c) Simplicity: easy to understand, easy to use and d) Guidance through recognition and intuition. Suggestions as to how the identified principles can be implemented to support persons with cognitive impairments in the identified domains of kitchenrelated activities were developed and presented to stakeholders in a second round of focus groups to gather their reflections. This article presents and discusses suggestions for design of a “cognitive kitchen” developed through the study.

    Design of an evaluation of technology, organisation and care for extended living at home by persons suffering from acquired brain injury or dementia: From Virtuality to Reality2005In: Assistive Technology: From Virtuality to Reality / [ed] Pruski, A; Knops, H, 2005, Vol. 16, p. 343-347Conference paper (Refereed)
    Abstract [en]

    Assistive technology is expected to facilitate life at home for people with various kinds of cognitive disorder. To study the applicability and adaptation of a number of aids in the daily living at home a three-years project have been launched in Sweden. It consists of undertakings in three municipalities, each planned to comprise some twenty participants about sixty years of age and upwards, suffering either from an acquired brain injury or from dementia. The goal is to acquire knowledge and experience about technical aids, their appropriateness and adaptability to the caretakers and to the organisation supporting them. The housing companies play an important role for the development of the project, as many technical aids are intrinsically linked to the physical building structure. The authors are engaged in the evaluation of the entire project which is in its starting phase. This article outlines some basic principles of the planned evaluation.

    Inclusive Design Instead of Assistive Technology in Housing2008In: Proceedings of the 4th Cambridge Workshop on Universal Access and Assistive Technology / [ed] Clarkson, PJ et al ( Eds), 2008, p. 107-112Conference paper (Refereed)

    Abstract

    The growing number of inhabitants in need of care and rehabilitation is a common problem in most industrialised countries. More medical conditions can be treated, but often at increasing costs. Care and housing are often interlinked and more interest is being paid to the possibility of offering care to elderly in their own homes. It is not only technology and care that matter; an equally important issue is how well the dwellings are adapted to care, both from a spatial perspective and in supporting new technology. It is a relatively widespread opinion that ICT (Information and Communication Technology) has the potential to support the resources of the caring professions without reducing the quality of the care itself. The complexity of relatively simple technology in use with Home Care and Telemedicine is often underestimated; there are many obstacles.

    In order to conduct applied research about assistive technologies and ergonomics when an apartment is also a work place for professionals giving care and assistance to people in their own home, the University has decided to construct a full scale laboratory in the form of two complete, self-contained and fully equipped apartments. The laboratory will be used to study and develop new technologies and work processes in the home. In different zones such as the kitchen, the bedroom, the living room, the hallway, the cloakroom and the bathroom, there will be different research projects implemented. Subjects and professional care staff will be invited to participate in the studies.

     In different zones there will be different research project implemented:

     In the bathroom we will develop design for assistive work respectively design for independent intimate hygiene. The Japanese toilet style which include cleaning and drying system will be tested.

    In the bedroom we are planning a lightning system for light close to the floor as a guide when one goes up in the night time.

    In the kitchen we will investigate how to create good lighting and storage conditions while preventing old people from falling when trying to replace a bulb or climb to high cupboards.

    In the kitchen new approaches to deal with fire risk and the stove and oven will be studied.

    In one project we have planned to study how the access to the apartment can be dealt with in ways that support the elderly person with memory problems and the healthcare provider.

     

    By using a full scale laboratory where tenants and caring professionals as well as facilities managers are included, all aspects of the apartment can be scrutinized. Instead of assistive technologies the goal is to develop and test solutions based on the concept of inclusive design.

    Belysning i Bostaden2009Report (Other academic)
    Abstract [sv]

    Behovet av ljus ökar med stigande ålder och bristande belysning kan vara en orsak till att särskilt äldre människor snubblar och faller med skador som följd. Linköpings kommun har genomfört en belysningsstudie bland dagens äldre i Linköping vars syfte varit att få kunskap om vilka behov av åtgärder kring belysning som finns hos de äldre. Studien har finansierats inom ramen för programmet Teknik för äldre som administreras av Hjälpmedelsinstitutet på uppdrag av Socialdepartementet.

    Ögat förändras under åldrandeprocessen och redan i 40

    -års åldern kan man märka hur synen blivit sämre än den var vid yngre år. En person i 40-års åldern behöver dubbelt så mycket ljus som en person i 20-

    års åldern för att kunna läsa eller skriva. För äldre kan också ljus i form av ljusterapi ha en mycket god effekt på sömn och välbefinnande. Frågan om belysning är därför starkt relaterad till ålder. Marknaden för belysning utvecklas idag i rask takt. Ny teknik att skapa ljus i form av lågenergilampor eller lysdioder (LED) bidrar till denna utveckling.

    Rapporten presenterar hur de intervjuades belysningsförhållanden ser ut idag och vilka problem eller önskemål de intervjuade upplever kring belysning i bostaden.

    Men belysningen i äldres hem har inte bara betydelse för deras egen hälsa och välmående. I takt med att allt fler får vård och omvårdnad i sina bostäder blir bostaden också en arbetsplats för dem som ger vården. Det blir en balansgång mellan att undvika att bostaden utrustas och upplevs som en vårdplats, och att ge dem som vårdar den äldre i bostaden goda arbetsvillkor.

    Resultatet av intervjuerna som gjordes både som strukturerade intervjuer och som djupintervjuer samt med okulär besiktning av bostäderna, visar att de intervjuade oftast har alldeles för svag belysning. Särskilt visar det sig i sådana utrymmen där risken för fallskador är störst. I hallen och i vardagsrummet är belysningen oftast mycket bristfällig. I hallen för att det inte finns så många möjligheter att installera ljus eftersom det traditionellt finns ett takuttag där det oftast sitter en plafond med alldeles för svag glödlampa. På väggarna finns oftast bara ett eluttag som används till spegelbelysning eller dekorativ belysning.

    Ett annat problem utgörs av svårigheterna att byta glödlampor i taket. De äldre vågar inte ställa sig på pallar eller stegar för att byta glödlampor, eftersom de ofta har problem med balansen. Likaså är sladdar på golvet ett återkommande problem.

    Safety at Home for People with Cognitive Disorder: the Installation Process2006In: Accesibility and Safety for All - International conference PTE-Expo, on March 2006 in Verona, Italy, 2006, p. 1-10Conference paper (Refereed)
    Abstract [en]

    Assistive technology is expected to facilitate life at home for people with variouskinds of cognitive disorder. To study the applicability and adaptation of a number ofaids for this group in their daily living at home a three-year project was launched inSweden 2004. It consists of undertakings in three municipalities, each planned tocomprise some twenty participants, sixty years of age and older, suffering either fromdementia or from some other acquired brain injury. In the second phase of theproject, now under way, the complexity of the installation process of assistivetechnology in ordinary homes has emerged as a crucial issue. If the project will besuccessful and able to offer a model for other similar undertakings in the future,efficient and reliable installation procedures will become indispensable. The verymoment of installation is considered and concern is paid to the functionality of theequipment over a long period of time. Assistive technologies applied for the sake ofsecurity for this target group comprise, i.a., automatic or manual alarms, smartsensors, automatic switch off systems, reminders and illuminated night paths to thebathrooms. Typical examples are security systems like the “go-away” lock and thereminder-panel. People with some cognitive dysfunction, still living in their ownhomes, are prone to forget to switch off the stove, the iron or other equipmentinducing a potential risk of fire. The paper describes the installation process of areminder system and some important findings from the study.

    On the role and potential of IoT in different industries Analysis of actor cooperation and challenges for introduction of new technology2017In: 2017 JOINT 13TH CTTE AND 10TH CMI CONFERENCE ON INTERNET OF THINGS - BUSINESS MODELS, USERS, AND NETWORKS / [ed] Falch, M, IEEE , 2017Conference paper (Refereed)
    Abstract [en]

    In this paper we study how IoT technology can be introduced and used in different sectors; industrial IoT, smart energy, smart homes, smart cities, health care and social care, sports and well-being. The research has given increased insights into opportunities and obstacles for the introduction of IoT in different sectors. The main obstacles are considered to be i) specific IoT solutions often tend to be a small part of the overall solution, ii) lack of knowledge about which overall services the IoT solution may be part of, iii) Fragmentation and insufficient scalability, iv) Distrust and hesitation among actors to share data and platforms and finally, v) fear of changing the own business model. The analysis of our cases indicates that most of the challenges occur due to the fact that the solutions initially have been developed using a single firm business model. In order to survive or grow a networked business model is needed.

    Fostering communication between the elderly and the youth with social games2015In: Pacific Asia Conference on Information Systems, PACIS 2015 - Proceedings, 2015Conference paper (Refereed)
    Abstract [en]

    In today's aging societies, elderly people often have difficulties to find people to communicate with. To address this loneliness of the elderly, it has been suggested to create more opportunities for children and elderly people to engage in various shared activities together. In this ongoing research, we investigate that social offline games can facilitate communication between the generations by creating a mutually enjoyable environment where elderly and young persons can interact with each other. A longitudinal approach is used to investigate whether intergenerational communication actually is enhanced by utilizing social offline games as the medium. Prior research has been conducted in related topics, such as the perceptions of the young and elderly participants towards each other in a game setting, as well as the impacts to communication behaviours among players of the same generation. We aim to build a model that connects game enjoyment, intergenerational perceptions and communication, and ultimately contribute to improving the well-being and relieving the loneliness experienced by many elderly people.

    Long-term viability of smart home systems - Business modelling and conceptual requirements on technology2005In: Home-Oriented Informatics and Telematics, Proceedings / [ed] Sloane, A, 2005, Vol. 178, p. 71-86Conference paper (Refereed)
    Abstract [en]

    Stockholm during the years 1999-2002 some residential housing units provided with advanced IT-based functions were developed, also called smart homes systems. ne purpose was to offer the residents an augmented living environment mainly regarding security and comfort. Only the IT company that originally developed the basic system fully knows it in depth, a fact which has shown to become very unfavourable for the residents. The running cost, also for minor changes of the functionality of the system, has turned out to be high and prohibiting. Also the contracted regular maintenance requires access to unique competence, which also has become costly. Recently the company has indicated a replacement of the smart homes system with a simpler one based on the Internet. Business models for viable home systems should include the occupancy phase, which to date have been neglected. A crucial issue is who will and can assume long-term responsibility for surveillance, maintenance, and added functionalities over time. This paper will discuss some principal questions and prerequisites regarding business viability in relationship to smart home systems, and its significance for business modelling.
