Visuomotor control of 3D circular tracking movement in a virtual reality space

Abstract

We developed a system that allows users to quantitatively evaluate visuomotor movement based on 3D target tracking in a 3D virtual reality space. It is verified that 3D visuomotor control under monocular and binocular conditions could be analyzed quantitatively. We found that the tracking system is more useful to adopt the parameters of Δθ, and Δω to analyze the circular tracking movement with increasing speed. In addition, we also found that the parameter of ΔR was not suitable for the analysis of low-speed movement. When tracking movement, we also found that the visual dependence was large and had a great influence on the accuracy of the movement. The proposed system can be useful for assessing the severity of the disease and the rehabilitation of people with hemiplegic upper arms. The system can also be adopted to research people with the perception of spatial neglect.
