Abstract

Many contrivances to give a button image solidity have been used in an interface design in order to enhance convenience for users by evoking operation to associate the real one. The previous study shows that it is possible to perceive the three dimensional space from the two dimensional image with the luminance change via linear gradation. As with the spread of touch-panel terminals in recent years, many studies about the interface design for touch-panel terminals have been conducted, however less studies about the brightness value of the linear gradation have been conducted. We conducted an experiment about the luminance value of the linear gradation in gray scale, focusing on a button solidity in a touch-panel terminal in this study. As a result, strong correlation was observed between the highlight and the shadow of the gradation, the average brightness difference between the two was 63.22% and the true value was between 62.20% and 64.23%.
