AVA: An Audio-based Virtual Aiming System for Accessible VR Shooting Games

Video games provide a rich source of entertainment and social interaction, yet they remain largely inaccessible to blind and visually impaired individuals (BVIs). AVA is an Audio-based Virtual Aiming system designed to guide BVIs in shooting video games using sonification methods in Virtual Reality (VR). Our current goal is to design sonification methods that simultaneously optimize the accuracy and speed of shooting tasks in VR games for BVIs. We are currently conducting two successive experiments comparing three sonification methods (Pitch, Tempo & Pitch and, Binary Pitch & Tempo), and two configurations: one exploring the impact of adding a sound at the center of targets, the other examining different sound spatialization approaches to facilitate target localization.
