There are many references on "Information Theory" that treat information amount and entropy, but no study has been reported on the practical usage of this theory. In this study, this theory was tried on the recognition time of station selecting button number for automobile radio. Process to seek button number is considered to depend on button arrangement, and recognition time to depend on the information amount and entropy possessed by the button arrangement. So information amount and entropy were calculated and recognition time was measured, for three types of button arrangement : one set of six buttons (1×6), two sets of three buttons (2×3) and three sets of two buttons (3×2). It was found that there is a strong correlation between entropy (average information amount of each button arrangement) and average recognition time of six buttons, for three types of button arrangement. To seek by smaller entropy, average recognition time was found to be shorter. Recognition time, especially for the inner ones of six buttons was found to become shorter by dividing six to two or three sets.
