Effect of Input Device on Search Time of Tree Structured Menu

Abstract

To design user interface of menu selection system based on human kansei and intention, both of two design elements, (1) menu tree structure and (2) device, should be selected properly to show and select given items. This paper investigates and analyzes the effect of both (1) and (2) on user's search processes in a hierarchical menu selection system. The results of the experiments, in which the input user interface and hierarchical menu structure are varied along with models of user behavior show that both of (1) and (2) affect search time and usability.
