Study of the effect of age and disability on the action of moving a cursor onto a target using a mouse and activating the target via a left-button press. Point-and-click data gathered from 3 groups of 6 adults each, aged 20-30 (young adult), 35-65 (adult), and 70 and older, and one group of 6 adults with Parkinson’s disease, were analyzed to show the differences in pointing performance between the groups. Data were collected on both the cursor movement and button-pressing measures. Results indicated that seniors take longer to complete the task and pause more frequently than the other groups; however, some seniors were less experienced using a computer mouse, which could in part account for this. Overall group times and number and distribution of pauses recorded in the users with Parkinson’s disease were consistent with the average age of the group, which could be attributed either to age or the effect of the disease. The study concludes that the differences in behavior recorded with respect to established models of movement indicate that new models are required when considering older users or those with physical impairments.
