Abstract:
Augmented-Reality (AR) has already been applied to many areas and applications, but there is still a lack of research on the appropriate interface considering the usability of AR devices. At present, the main input methods of HoloLens can be classified into two categories: hand (gesture) and clicker. In this work, participants wear HoloLens and perform target selection works. We measure the task completion time, user satisfaction score and error rate to check the effects of the input methods, button sizes, and distances. The Latin Square design was used to minimize the effect of the order. Then, a questionnaire was conducted after each treatment. In this paper, we compared the performance changes by input methods, button size, and distance in HoloLens. There was a significant difference in input method, distance and button size. Task completion time and user satisfaction were better with the large button than the small button, and the error rate was higher with the large button. In task completion time and user satisfaction, the clicker performed better than the hand. The task completion time and the user satisfaction were better in 80 cm and 100 cm than 60 cm.
