Abstract

In this study, we developed a new performance model that utilizes the index of difficulty to predict the pointing time which required for a point-ing task when using a PC mouse. Forty-nine subjects were classified into three age groups: young, middle-aged, and elderly. Experimental factors were target size, target distance, and approach angle to the target. All the experimental factors were within-subject variables. The time for pointing and the coordination of the pointer (mouse cursor) were measured under all conditions. The pointing time was significantly longer for the elderly group than for the young and middle-aged groups. Moreover, the pointing time in each age group tended to increase linearly with an increase in target distance and to decrease as a logarithmic function with an increase in target size. The trajectory of the cursor from the starting point to the click tended to increase linearly according to the distance to the target and to decrease slightly depending on the size of the target. Furthermore, the angle of approach influenced the length of the trajectory. Based on these results, we proposed a new model for measuring performance when operating a PC mouse. Our model received a higher rating for ease-of-use than conventional models. It was clarified that the performance model for elderly persons was different from that for other age groups using the proposed model.
