Résumé

Virtual reality (VR) technology offers an immersive experience, transporting users to simulated environments through specialized headsets. Advancements in haptic feedback using tactile sensations have been remarkable, but the area surrounding the ears, with high haptic sensitivity, has been underexplored. This paper delves into the effectiveness of vibration headphones (VH), specifically the Razer© Kraken V3 HyperSense, in providing directional information for object spatial localization in VR. The experiment examined haptic-only, audio-only, and audiohaptic conditions, comparing accuracy and completion time using a generic haptic-based Head Related Transfer Function (HRTF) developed by us. Participants (N=21) had to locate an invisible spheres using provided directional information based on feedback. Results revealed statistically significant differences in accuracy between audio-only and audio-haptic (p = 0.00053) and between haptic-only and audio-haptic (p = 0.0315). Interestingly, participants favored the haptic condition and ranked it as the most enjoyable while the completion time was similar for all our conditions. These findings highlight the potential of VH to provide directional information and the possibility to substitute the auditory channel for localization or navigation tasks. By focusing on the area surrounding the ears, developers can offer a new sense in VR.
