Study on Movement Characteristics of Fingers During Hand Grabbing Process
Grabbing objects is the daily behavior of the human hand. The joint angle and correlation during the grasping process are the main movement characteristics of the finger. In this study, the OptiTrack motion capture system was used to collect the data. The analysis shows that: (1) In the three grasping modes, except thumb, the angle of the middle joint on the same finger changes the most, the proximal joint is the second, and the distal joint is the smallest. (2) The movement of the joint of the thumb has the lowest correlation with other four fingers. The conclusions of this study can be used on human-computer interaction research, rehabilitation analysis, prosthetic design and bionic robot development.
