Abstract
Personlige lydzoner er områder, hvor lyd kan rettes, så forskellige personer i samme rum hører forskellige lyde. Forskere har i næsten 50 år undersøgt, hvordan man skaber sådanne zoner, men måderne, hvorpå mennesker skal interagere med dem, er langt mindre udforsket, blandt andet fordi teknologien endnu ikke er moden. For at imødekomme dette byggede vi et system, der simulerer både bevægelige (dynamiske) og faste (statiske) lydzoner for flere brugere. Dette system gør det muligt at gennemføre studier af rumlig lyd (lyd, der opleves som om den kommer fra bestemte steder). Som proof of concept gennemførte vi et eksperiment om gestusbaseret interaktion og om, hvordan lydzoner bør bevæge sig. Vi målte brugeroplevelsen med User Experience Questionnaire og exitinterviews. Vores resultater tyder på, at zoner bør bevæge sig gradvist frem for øjeblikkeligt, da øjeblikkelig bevægelse blev oplevet som aggressiv af nogle deltagere.
Personal sound zones are areas where audio can be directed so that different people in the same space hear different sounds. Researchers have explored how to create such zones for nearly 50 years, but how people should interact with them has received much less attention, partly because the technology is still maturing. To address this, we built a system that simulates both moving (dynamic) and fixed (static) sound zones for multiple users. This system makes it possible to run studies of spatial sound—audio that seems to come from specific locations. As a proof of concept, we conducted an experiment on gesture-based interaction and on how sound zones ought to move. We measured user experience with the User Experience Questionnaire and exit interviews. Our results indicate that zones should move gradually rather than instantly, as instant movement felt aggressive to some participants.
