Abstract

Summary: Introduction: Use of notebook computer is growing rapidly worldwide and replacing desktop computer especially in the education and workplaces. Task performance and body discomfort among notebook computers user becomes a major concern, as it will directly affect the productivity and health with extensive notebook computer used in the workplace. Objective: The aim of this study is to evaluate the effects of using an external computer mouse with different sizes and at different positions when using notebook computer. Methods: 52 Subjects were recruited in this experimental study to perform text-editing task over 10 minutes using large and small computer mouse at three different mouse positions (LC, LR, LF, SC, SR and SF) in a designed workstation. Their text-editing performance were calculated as total number of words edited correctly and the individual discomfort ratings were measured using visual analogue discomfort scale (V ADS). Results: The results showed significant mouse size effect and interaction between size and position in task performance (p < 0.0001). The overall highest task performance was at SC condition. However, the highest task performance for large mouse, the least self¬discomfort value and the highest individual preference were at LF condition. There was no significant correlation between task performances and self-discomfort, however the relationship was negative in small mouse but positive in large mouse. Conclusion: In conclusion, the interaction between mouse size and mouse position has an important role in affecting task performance. The point of interest raised in this paper is selection of mouse size and mouse position and suggestion of an ergonomic posture in the usage of notebook computer together with external device. Keywords: Computer mouse, task performance, discomfort, ergonomics, notebook computer
