Analysis of mechanical impedance in human arm movements using a virtual tennis system.
The dynamic characteristics of human upper extremities are usually expressed by mechanical impedance. Although many studies have discussed human impedance characteristics, there are no reports on control abilities of task-related impedance in skilled human hand movements. This paper proposes a virtual sports system using a virtual reality technique to examine human movements. The differences in movements between skilled and unskilled subjects are investigated through a series of experiments. Then, the human impedance of a skilled player is estimated and analyzed in the preliminary phase of motion.
