A Proposal of an Input Device Serving as an Unfixed Joystick

Abstract

This paper proposes an input device for video viewing. It serves as a joystick, while it is unfixed and portable. The authors made a prototype of this input device and carried out two experiments. The first experiment evaluated the recognition performance of users’ operation. The performance was qualified by precision and recall, and the result showed that the values of both of these two parameters had become high after repetitions of the operations by users. The second experiment performed a comprehensive evaluation of three input devices including the proposed one. The evaluation was based on NASA-TLX and Nielsen’s usability components, and the result showed that the proposed input device had high affective value and high learnability and that it is suitable for video viewing consequently.
