碩士 === 國立臺灣科技大學 === 工業管理系 === 94 === The aim of this study is to design and validate a remote, finger-operate, input device (FOI). Cursor location of FOI was determined by using a gyroscopic motion sensor. The design concept of FOI followed NSC mouse that was developed in the laboratory. Two experiments were conducted to test and verify the benefits of the FOI. Thirteen males and seven females participated in the study (means age 24.6 years). The first experiment was to compare performance of a wireless mouse, joystick, and FOI in a Fitts’ law task. The result showed that the pointing time of mouse was 0.70 sec and the error rate was 7.8 %. For FOI, it was 1.29 sec and 13.2 %, and was 1.99 sec and 21.0 % for joystick. In the dragging task, mouse time was 0.68 sec and the error rate was 4.0 %. It was 1.22 sec and 10.1 % fro FOI, and was 1.98 sec and 22.8 % for joystick. The second experiment was to examine performance time of two tasks while using a wireless mouse, a remote controller for a media center edition (MCE), and FOI in a multimedia scenario. The results showed the performance of FOI is better than that of the remote controller in the multimedia application. To strengthen the exquisiteness degree of FOI, it was suggested to decrease the weight of gyroscopic motion sensor, to improve user skill, and make performance of the whole display the optimization even more
