In this study, we analyzed the old`s characteristics for depth perception in comparison with the young`s as a basic study for universal design in field of products or facilities. Twenty three of the old and twenty two of the young had participated and the depth perception apparatus was used in this experiment. Gender, viewing distance, and age were considered as factors and the differences of depth perception were analyzed for each experimental condition. In the result, a significant difference was not detected on gender, but significant differences were detected on age and viewing distance. That is, we can see that the old is remarkably worse than the young on depth perception task. Therefore, it means that these characteristics have to be absolutely considered in user interface design to improve the old`s accessibility for products or facilities.
