How does shape of a progress bar effect time evaluation?

Abstract

The main purpose of this research is to satisfy personal computer users by visual perception perspective. There are many kinds of task related to time evaluation on application. Most researches focus on processing speed. We focus on application interface that inspired by visual perception methods to satisfy users. This study attempts to find relationship between progress bar design components and subjective speed by subjective evaluation experiments, and apply experimental results to a software interface design. We prepared the 10 different shapes of progress bar, displayed each progress bar taking time around 10 seconds to be completed, and let subjects to answer how long they felt. As a result, the quarter ring shape makes subjects feel short. We examined the experimental results through a software interface design. In this paper, we introduce two conflicting psychological opinions about time evaluation and show experimental results. As a future work, we should investigate influence of display time.
