Visual Feedback to Reduce Influence of Delay on Video Chatting
When there is a certain delay in video chatting, participants often misunderstand other partners’ response and make unintended interruptions. In this paper, to overcome these problems, we present two kinds of visual feedback: Scroll Wave Indicator and Afterimage Indicator. An experiment was conducted to confirm effectiveness of these indicators. The result of experiment showed that the Scroll Wave Indicator helped participants to understand the remote participant’s response timing and decreased unintended interruptions even if there was 2 [sec] round-trip delay.
