Popis: | This research had a systematic study on arm fatigue issue in free hand interaction in VR environment and explored how arm fatigue influenced free hand interaction accuracy. A specifically designed target-acquisition experiment was conducted with 24 volunteered participants (7 left-handedness, 17 right-handedness) recruited. The experiment results indicated that (1) arm fatigue resulted in short durations of hand operation, or frequent alternations of operating hand. The user’s dominant hand had a more durable operation than the non-dominant one; (2) hand operate position had a significant effect on arm fatigue level, a bent arm posture was found to be more labor-saving than an extended arm posture, (3) hand operation at a higher position (e.g., at the head height) perceived arm fatigue more easily than that at a lower position (e.g., at the waist height); and (4) arm fatigue impact hand interaction accuracy negatively. |
