Gamers and Non-Gamers: Differences in User Performance and Muscle Activity for Different Mouse Control-Display Gain
DescriptionThis study investigated the differences in muscle activity and user performance between gamers and non-gamers under different computer mouse control-display gain settings. A total of 15 gamers and 15 non-gamers were recruited to perform five 30-minute Fitts' Law tasks under five different control-display gain configurations. Surface electromyography (sEMG) was used to monitor muscle activity in the extensor digitorum, extensor carpi ulnaris and flexor digitorum superficialis. User performance measures were recorded using GoFitts software. The results showed differences in upper limb muscle activity and task performance between the two groups. Specifically, gamers showed superior performance compared to non-gamers, and muscle activity patterns varied inconsistently across gain settings. These findings could inform the development of ergonomic mice tailored to the gaming community and reduce the risk of muscle fatigue.
