| Background As the long-term use of a mouse has become generalized in education sand practical sites for contemporary design, there have been growing concerns over physical fatigue and declined work efficiency. In the case of existing mouse design, its function and shape were a major focus, and there have been relatively few studies on ergonomic design improvements for addressing user experience (UX) and physiological responses. Therefore, this study aims at proposing the direction for an integrated design framework encompassing functionality, usability, shape, and expandability for mouse design.
Methods In the first phase of the study, a survey was conducted with 91 graphic designers for evaluating user experience, satisfaction, and purchase intention in relation to mouse design and then, Multiple regression analysis and analysis of variance (ANOVA) were made to verify the correlation between design elements and behavioral responses. In the second phase of the study, the comparison between existing and improved mouse designs was made through postural load analysis (video analysis) and a comparative electromyography (EMG) assessment. It was to analyze differences between two designs in muscle load and postural stability.
Result From the survey, it was possible to conclude that ergonomic design, click responsiveness, weight, and grip comfort have significant influences over user satisfaction, and purchase and usage intention. Especially, the sensitivity to wrist fatigue was shown to be high, and in the use of the improved mouse design, there were a decrease in muscle activity and an increase in postural stability.
Conclusion This study suggests a mouse design guideline, developed upon the comprehensive analysis of user perception and bio-mechanical responses, aimed at reducing musculoskeletal strain while enhancing user satisfaction. The findings of this study are anticipated to contribute to the advancement and development of UX-based input device designs, and provide practical insights for developing user-friendly design strategies. |
