| Popis: |
Eight participants conducted representative flight deck display interaction tasks using a touch screen fitted with four hand stabilization methods in turbulent motion conditions simulated by off-road driving on a bumpy surface. A variety of objective and subjective data were gathered including workload, time on task, error rate, and electromyography (EMG) captured at the participants' forearms. Results indicated no significant differences in task performance across the hand stabilization methods, while preference ratings and comments significantly favored the “rails” hand stabilization method. EMG data indicated that the “slider” stabilization method reduced the variability in the EMG signal for all subjects. The results suggest that participants required at least some form of hand stabilization to support completion of flight deck tasks when using a touch screen in turbulent conditions. |
