Comparison of Perceived Waiting Time Between Two Lengths of Progress Indicator and Two Styles of Graphics Animation With Perceived Uncertainty as a Covariate

This paper addressed the issue of waiting time in HCI through a psychological view, especially through models of time perception (Attentional Gate Model) with the primary objective of this study is to investigate the effect on PWT between two length of progress indicators and two styles of graphics animation to provide the guideline which can be followed by web developers to enable faster and more efficient website to serve their user. The laboratory experiment was set up with a 2*2 pattern of progress bar. The results provide empirical evidence of the impact between the size of progress bar on PWT while the ribbed animation does not. Therefore, the result provides a strong support for the proposed model and emphasize the importance of managing online waiting perception. The findings of this study may serve as a useful input to web developers and symbol designers for creating shortly perceived loading symbols.
