In this study we investigated the influence of sound when interacting with a target button with constant size and distance on a 2-dimensional plane on a computer screen. In particular we wanted to verify if the use of auditory stimuli could improve the time it takes for a user to reach the target button with mouse as an interface. We conducted experiments in which participants had to click a button with the aid of visual stimuli only, audio stimuli only, or a combination of both visual and audio stimuli. Participants performed faster with audio-visual stimuli than with audio stimuli only. Because of inconclusive results we could not prove that audio- visual stimuli always yields a faster time average than visual stimuli only.
