Abstract
Extended computer mouse usage may lead to health problems including chronic pain and musculoskeletal disorders. The weight of the computer mouse is an important feature of mouse design. However, the impact of mouse weight on gaming has not been explored. This study assessed the influence of mouse weight on muscle activity, performance, and user preference. Twelve participants participated in this study. Participants used six computer mice (40g-140g) to perform a Fitts' test and gaming tasks. Wireless surface electromyography was used to record muscle activity. Fitts’ test was used to measure the performance. User preference assessed discomfort and overall preference. The results showed that muscle activity was slightly lower when using the heaviest mouse (140g); differences were not statistically significant. The lightest mouse (40g) had the highest error rate. The 60g mouse received the highest overall preference score, likely because it optimized performance while minimizing discomfort.
