Exploration of Sound Design and Sound Representation Techniques for Improving Inclusiveness, Player Performance, and Player Experience in Video Games

Abstract: This study aimed to explore sound design and sound representation techniques to strengthen the inclusion of players with sensory disabilities alongside non-disabled players. Additionally, it aimed to identify characteristics in inclusiveness components for video games. Tap Tone is a 3D action-adventure prototype with iteratively improved inclusiveness components based on research and requirements analyses. Twenty-five participants were recruited for user tests and divided into four groups: 1) non-disabled, 2) vision impaired, 3) deaf and hard of hearing, and 4) blindfolded players. Data were collected with a questionnaire and saved in-game data. The data was analyzed using statistical methods, including ANOVA and a t-test. Results indicate that the experience for deaf and hard of hearing is significantly different from the groups vision impaired and non-disabled. The results indicate similarities in experience for non-disabled and vision impaired players. Moreover, the player performance indicates similarities between the groups non-disabled, vision impaired and deaf and hard of hearing. Finally, the study identified and discussed key characteristics of the inclusiveness components.
