Color Effect on Subjective Perception of Progress Bar Speed

摘要

This present study attempts to find relationship between progress bar colors and subjective speed by subjective evaluation experiment. We prepared the six combinations of colors, blue/red for progress bar foreground color and cyan/orange/gray for background color. The test progress bars are designed under the same condition, for example progress bar size or animation speed, except colors. The test progress bars were displayed one after the other of all pair combinations, and made the subjects mark the test progress bar which they felt faster. As a result, there were no obvious significant color effects related to subjective speed impression in this subjective evaluation experiments. We consider the reason why not found significant color effects as follows, (i) it's not enough data due to the small-scale experiments with only 10 subjects, (ii) color effect might not strong on progress bar.
