Characteristics of Perceived Time Depends on UI Expression of Waiting Time

In recent years, there have been some displays of the order number or how long users must wait on the screen to help with waiting time in restaurants and public places. In this study, we focus on users’ waiting time on a website. We compare how the perceived time changes depending on the UI of the progress bars. Moreover, we also visualize the compared results, including participants’ impressions. Namely, this research aims to clarify what kind of UI and participants’ impressions influence their perceived time. In the experiment, 33 Participants saw the six videos with different progress bar expressions and evaluated their impressions of each expression. We experimented with six videos divided into two groups. Group 1 was the group that changed the speed at which they were shown, and Group 2 is the group that changed the way of display. After evaluating the six expressions, they made a rank with six expressions and answered the reason for the rank order. Moreover, we conducted the Factor analysis using the SD method results, and we extracted the three factors; ‘Novelty,’ ‘Openness,’ and ‘Dullness.’ Primarily, ‘Dullness’ was related to the perceived time. From the ranking results, the perceived time can be increased or decreased by changing expression even though real-time is the same.
