En lekfull virtuell verklighetsmiljö som underlättar energieffektivitet av Sonic Interaction : Ljud för energi i virtuell verklighet (Swedish)
Abstract [en]

In Europe, households account for 25% of the energy-related greenhouse gas emissions. This report describes the implementation and evaluation of a playful virtual environment, where different interactive sound designs are used to implicitly promote household energy efficiency behaviors. Nine participants were recruited and assigned randomly to three testing groups with varying design schemes. The energy consumption data in the environment, participants’ Virtual Reality (VR) experience and musical education backgrounds, their subjective scales of sounds, and semi-structured interviews, were used to analyze if the sounds were properly designed. Inherent advantages of VR were verified, in both aspects of immersion and spatialization of sounds, while it failed to overcome the difficulty in communicating energy information to users, where implicit interactive sounds conveyed the information. However, people’s different expectations of household sounds and how they perceived the interactive sounds were recorded, potentially contributing to further research on sonic interaction in sustainability.

Abstract [sv]

I Europa står hushållen för 25% av de energirelaterade växthusgasutsläppen. Denna rapport beskriver implementeringen och utvärderingen av en lekfull virtuell miljö (VR), där olika interaktiva ljuddesigner används för att implicit främja energieffektivitetsbeteenden hos hushåll. Nio deltagare rekryterades och fördelades slumpmässigt i tre testgrupper med olika designscheman. Energiförbrukningsdata i miljön, deltagarnas VR-upplevelse och musikaliska utbildningsbakgrund, deras subjektiva skalor av ljud samt semi-strukturerade intervjuer användes för att analysera om ljuden var korrekt designade. Inneboende fördelar med VR verifierades, både när det gällde immersion och rumsligisering av ljud, samtidigt som systemet misslyckades med att övervinna svårigheterna när det gäller att kommunicera energi-relaterad information med implicit interaktiva ljud till användarna. Däremot dokumenterades skillnaden i förväntningar kring hushållsljud mellan människor och hur de interaktiva ljuden uppfattades, vilket potentiellt kan bidra till den fortsatta forskningen inom ljudinteraktion för hållbarhet.
