Abstract
Access to sports for visually impaired people is often limited by a lack of adapted tools. This study explores sonification to improve aiming in blind shooting. Four methods were tested: (1) pitch only (PO) (the traditional method), (2) pitch plus white noise at the target center (PWN), (3) pitch/stereo for horizontal and timbre for vertical, presented stepwise (PSTseq), and (4) the same but simultaneous (PSTpar). Accuracy, speed, and ergonomics were evaluated in a shooting task using a motion capture system. All new methods outperformed the traditional one. PWN notably improved precision and usability. PSTseq allowed the fastest aiming, which may benefit time-constrained sports like laser-run. These findings open new possibilities for sonification in sports or video games. Future research should explore more realistic sports contexts.
