Abstract
A robot-assisted hand-eye coordination training system based on a smooth pursuit eye movement and a guidance force field includes a virtual interactive scene module, a smooth pursuit eye movement detection module, a robot-assisted interception module and an impact force rendering module. The virtual interactive scene module can generate a virtual interactive scene having a virtual moving object and a virtual handle agent. The smooth pursuit eye movement detection module collects an eye movement signal of a user when the user performs pursuit eye movements on the virtual moving object to detect a smooth pursuit eye movement event. The robot-assisted interception module estimates a movement direction of the virtual moving object, generates an interception and guidance force field, and therefore generates assisting force to assist the user in interception. The impact force rendering module generates impact force according to an impact force computation model after collision is detected.
