In this study, we clarified the differences in the pointing time required when using a touch panel and a PC mouse for three age groups: young, middle-aged, and elderly. We constructed a performance model for a touch panel operation (Experiment 1). Moreover, we investigated the visual interference caused by a multi-target presentation (Experiment 2). The delay caused by visual interference for the right-hand target was longer than that for the left-hand target, and that for the upper target was longer than that for the lower target.
