Accessibility Of Shooting Task For Blind And Visually Impaired: A Sonification Method Comparison

Abstract

Access to ordinary sports clubs or video games is limited forblind and visually impaired people (BVI) which reduces mixedability practices and social inclusion. To adapt shooting videogames and sports to BVI, we analyzed the literature to find sonification methods able to support targeting tasks. We identified fourconvenient methods ("Pitch Only", "Tempo & Pitch", "Tempo &Binary Pitch", "Chroma, Beats & Roughness") outcoming fromother application fields such as medical assistance, navigation, orphotography. To determine the best suitable sonification for shooting contexts, we carried out a within subject experiment in a 3Dvirtual reality environment. 24 sighted participants were askedto shoot as fast and accurately as possible on invisible targets,guided by sonic feedback only. With future mixed ability practices in mind, sighted participant’s performances were also evaluated through a visual control condition. Results showed that participants were shooting faster in the visual condition, but more accurately in the audio-only conditions. "Chroma, Beats & Roughness" sonification lead to slower aiming time and more mentallydemanding efforts than the three other methods. Analyses finally suggest that participants preferred to associate both pitch andtempo. Lastly, future participation of BVI persons will allow todeepen the results.
