Abstract
Dette projekt undersøger brugeres oplevelse af kropslig tilstedeværelse (embodiment) i Virtual Reality – altså følelsen af, at den virtuelle krop er ens egen, og at man er til stede i den virtuelle verden. Vi ser på tre funktioner, der kan påvirke denne følelse: haptisk feedback (små vibrationer eller tryk), mulighed for at interagere med omgivelserne, og tilknytninger til miljøet, der forbinder den virtuelle krop med omgivelserne. Med det kommercielle VR-udstyr HTC Vive udviklede vi en VR-oplevelse i fire versioner: en fuldt interaktiv kontrolversion og tre versioner, hvor én funktion ad gangen var fjernet (non-haptic, non-interactive og detached). 17 deltagere gennemførte alle fire versioner i forskellig rækkefølge efter en kort tutorial. Vi evaluerede oplevelsen med spørgeskemaer og bevægelsessporing. Resultaterne viser, at både interaktion og haptisk feedback øger oplevelsen af embodiment. Derimod havde tilknytninger til miljøet ikke nogen målbar effekt.
This project examines how users experience embodiment in Virtual Reality—that is, the feeling that the virtual body is one’s own and that one is present in the virtual world. We focus on three features that might influence this feeling: haptic feedback (vibrations or pressure), the ability to interact with the environment, and attachments to the environment that connect the virtual body to its surroundings. Using the commercial HTC Vive system, we built a VR experience in four versions: a fully interactive control version and three versions with one feature removed at a time (non-haptic, non-interactive, and detached). Seventeen participants tried all four versions in different orders after a brief tutorial. We evaluated the experience with questionnaires and motion-tracking data. The results show that both interactivity and haptic feedback increase users’ sense of embodiment, whereas attachments to the environment had no measurable effect.
