Abstract

A large amount of study about multisensory feedback for touch screen has been conducted, but multiple unisensory feedback has not. In this study, we investigated both objective and subjective evaluation of multiple visual feedbacks on touch screen. We presented two different visual feedbacks, either alone or combined, for QWERTY text entry. The results showed that the subjective evaluation of visual feedback 1 (Button feedback) was positive, while another visual feedback (Ripples) does not have any effect on evaluations. However, there was significant interaction between the two visual feedbacks. The effect of Button feedback was reduced while Ripples was provided. One possible explanation is that Ripples may not be appropriate for this task. Thus participants might ignore the Ripples feedback. Another is that multiple unisensory feedback might be too complicated, because these visual feedbacks overlap each other and moreover have different information.
