Movement Kinematics and their Relationship with Performance in Target Acquisition Task Using a Mouse

Movement kinematics has been shown useful for characterizing the process of aiming movement in target acquisition tasks. There are multiple kinematic measures reported in the literature, but their relationship to eventual performance is not well documented. To determine the relationship between various kinematic measures and movement performance, data were collected from participants aged 21 to 90 years with a wide range of psychomotor ability. When computed across age groups, time to peak velocity (TPV), time to peak acceleration (TPA), and time from peak velocity until the end of movement (TPVEND) were found to correlate with movement performance. However, the relationships diminished when the correlations were computed within age groups (except for TPVEND). More interestingly, despite the extensive report, certain kinematic measures such as peak velocity were found to be uncorrelated with performance. Thus, when performance is the focus, improvement should be made to reduce TPV, TPA, and TPVEND.Yeshttps://us.sagepub.com/en-us/nam/manuscript-submission-guideline
