動態環境下力搖桿於人機介面適度性之研究

Abstract

由於電腦功能日益強大與作業系統的快速發展，使得人機介面廣泛應用在各種領域，本論文探討在動態環境下力回饋搖桿是否適合做為人機介面之輸入裝置，我們進行了一系列的實驗，印證了運動時間與困難度間存在一線性關係，這也說明力搖桿適合作為人機介面的輸入裝置，而在搖桿的使用中，如何減少運動時間和降低錯誤率是一個重要議題，我們提出三種力輔助系統來進行改善，分別為主動力、被動力與提示力，實驗結果印證在運動時間和錯誤率方面皆有改善的成效;基於此研究，利用力回饋搖桿搭配力輔助系統，將可幫助使用者更精準完成任務。

Due to fast development of computers and operating systems, HCI (human-computer interface) nowadays has been applied to various fields. This thesis investigates whether the force feedback joystick is suitable to serve as the input device under dynamic environments. We perform a series of experiments and find that there is a linear relationship between the movement time and index difficulty, indicating that force-reflection joystick is a suitable input device for HCI. In addition, reducing movement time and error rate is an important issue for HCI. To deal with that, we thus propose three force-assistant systems including active force, passive force and reminding force. The experimental results show that these three force-assistant systems make improvement on the movement time and error rate. With this study, the user can manipulate the force-reflection joystick with the help of force-assistant systems to accomplish the task more rapidly and accurately.
