Abstract:
This research compares the impact of two different mouse curvature designs on comfort parameters, wrist muscle fatigue, and E-sport performance. Sixteen elite male right-handed E-sport players participated in the study, testing five different mouse models. Click performance, muscle activation signals, finger pressure, and 3D motion data were recorded. The testing involved five different mouse models (BenQ Zowie, FK1, FK1+, FK2, S1, S2) to compare hand ergonomics and comfort, with peak position and length as the parameters. Click performance was tested. Analysis revealed no significant difference in click performance between mouse models, but FK1 showed reduced fatigue after 60 seconds of clicking. Different curvatures resulted in varying wrist angles and fatigue levels. The results showed that bigger length and height on the back for symmetrical mouse did not provide a performance advantage, with the back tall design exhibiting higher fatigue. The mid-tall design showed less fatigue
and could potentially reduce wrist extension and stress on the carpal tunnel. This study provides insights into the impact of mouse curvature on hand ergonomics, comfort, and muscle fatigue in E-sport players, aiding mouse design improvements and consumer guidance.
