| The purpose of this research was to determine whether significant differences exist in speed and accuracy (verified by number of errors) between two input device types, mouse and finger (on a touchscreen), in a sample of adults between the ages of 65 and 80 years. User preferences for mouse and finger were also assessed in a 16-participant, one-day, 2 (Task Type: target selection and dragging) x 2 (Input Device: mouse and finger) fully within-subjects, repeated measures design study. The analyses revealed participants performed tasks faster and made fewer errors using a mouse input device than finger on touch screen. The participants reported the mouse required less force, less physical and mental effort to operate, and was more accurate for pointing than finger on touchscreen. Finally, participants reported a preference for the mouse overall for general comfort and ease of use. |
