Abstract

In order to develop remote controller designs well suited for ISDB(Integrated Services Digital Broadcasting), we performed experiments with elderly and young subjects to evaluate the usabulity and the training effects of four types of remote controller : a button type, a track ball, a touch panel and a voice recognition system. The reaction time for the track ball remote controller decreased substantially as the task proceeded, showing a clear training effect. We also conducted a post-experiment questionnaire survey among the subjects. The principal component analysis of the results shows that factors related to functionality contribute more than others such as design or uniqueness among the elderly subjects. In other words, elderly people tend to appreciate ease of operation more than eye-catching appearance or fun factors when making the evaluation.
