    Private and public digital domestic spaces2001In: International journal of human-computer studies, ISSN 1071-5819, E-ISSN 1095-9300, Vol. 54, no 5, p. 753-778Article in journal (Refereed)
    Abstract [en]

    With the introduction of information and communication technologies into our homes and the different physical and communicative expressions this implies for our living spaces the concepts of being private and of being public become crucial. In this paper, we introduce A Pattern Language, developed by Christopher Alexander in the 1970s, in order to handle these problems systematically. The presentation formally follows Alexander's structure in five cases all related to practical experiments on being private and public at home. We start with a number of concrete user situations related to human-computer interaction. Social and communicative phenomena or possibilities end up in novel design patterns at the interface between an architectural and a technological perspective. The novel patterns presented are primarily based on experiences from practical work on the development of a conceptual dwelling of the future, comHOME, designed and constructed as a full-scale model of a flat. By creating different zones for video-mediated communication, comZONES, the user can control the private and public digital areas varying in time and space. The novel patterns refer to two separate levels. On the first level a specific pattern, called PRIVATE AND PUBLIC DIGITAL SPACES, is designed as a conceptual floor plan layout. This plan distributes private and public digital spaces for video-mediated communication over the flat. At a second level, four patterns show the integration of the specific comZONES aiming at solving four specific problems with video-mediated communication at home. Our intention is to describe the application of design patterns as a method for analysing and solving novel problems encountered with the introduction of information and communication technologies in our homes. The video-mediated set-ups are not dealt with in depth. They serve mainly as designs that make it possible to apply the design patterns.

    User study of video-mediated communication in the domestic environment with intellectually disabled persons2003In: International Journal of Human-Computer Interaction, ISSN 1044-7318, E-ISSN 1532-7590, Vol. 15, no 1, p. 87-103Article in journal (Refereed)
    Abstract [en]

    A user study of video-mediated communication (VMC) involving six persons with mild intellectual disability is presented. It took place at comHOME, a full-scale model of an apartment of the future, showing innovative architectural and technical designs with regard to the integration of VMC into the domestic environment. Two different zones for VMC, comZONES, in the apartment, were tested, the videoTORSO (a large-screen set-tip for informal everyday,communication) and the workPLACE (a place for professional work tasks). The: purpose of the study was to get a deeper understanding of how people use these comZONES. The final discussion points out that the comZONES seem to be interpreted correctly and to function aptly in relation to the participants, in the study. An assumed explanation is that spatial recognition is a very fundamental human function and thus less significant with regard to the mental capacity of the individual.

    Work life, new technology and employment of disabled people: A twenty year programme2012In: Technology and Disability, ISSN 1055-4181, Vol. 24, no 3, p. 211-218Article in journal (Refereed)
    Abstract [en]

    A development programme was carried out by the Swedish government and the Swedish Labour Market Board (AF) over a period of more than twenty years. The paper describes a case history of a single national programme. Some significant conclusions from it are given. The rationale for the effort was the advent of micro-computers in the early 1980s and the ICT development in general. It was realised that people with disabilities would struggle in the job market if active measures were not taken. Within the AF expertise on different impairments and functional disorder was employed, often highly-skilled with many years of experience of helping people with workplace adaptations. In five years some 4000 jobs for disabled jobseekers were established by applying public procurement, partly on a pre-competitive basis. After these first five years the programme was regularised but still only as a development tool for another fifteen years, with a yearly budget of 0,5-1,0 M\psfig{figure=eur.eps,width=1.9mm}. The ICT technology offered successively a range of generative options, often pre-empting application to solutions beneficial for people having a variety of functional difficulties in their jobs. The projects were intended to include a potential to result in products or services on the open market. If new technology could be transferred into regular business, it would benefit the chief target groups and their procurers in the long run. One success case was Comfort Audio AB. The company was started in 1994 by two young entrepreneurs. Fifteen years later it employs some 60 people and finds its market all over the world with its cutting edge technology for hearing impaired persons.

    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.

    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.

    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.

    Smart home systems - Accessibility and trust2010In: Open House International, ISSN 0168-2601, Vol. 35, no 3, p. 6-14Article in journal (Refereed)
    Abstract [en]

    This article explores the residents' attitudes to and acceptance of Smart Homes. The results are based on surveys of two residential units fit with advanced smart home systems. The systems offered functionalities of different kinds as alarms, energy measurement, booking of common facilities, broadband connections and electronic keys. The buildings were first occupied in mid 2001 and early 2002, respectively. The original smart home systems were in operation until end of 2005, when they ultimately were replaced by simpler ones, based on the web, a change not foreseen from the beginning. The extended period of time offered the possibility to study the residents' long term attitudes, expectations and demands on smart homes with their installed and perceived functionality. The questionnaire surveys focused on the residents experiences and included questions of their actual use of the smart home systems and opinions regarding accessibility and easy of use. Albeit functionality related to current demand is a basic requirement, two other concepts, viz, accessibility and trust, have appeared to be fundamental for a positive attitude and acceptance of various functions that constitute a smart home. Related issues are developed and further discussed in the article.
