A Development of Kohs Block Design Test in Virtual Reality with Eye Tracking and Hand Tracking

The purpose of this study was to evaluate the effectiveness of the VR Kohs Block Design Test and the relationship between eye movements and hand movements by reproducing the Kohs Block Design Test in a VR space and measuring the subjects’ eye and hand movements during the test.Using the developed system, we conducted the actual Kohs Block Design Test and the Kohs Block Design Test on VR with three healthy adult male subjects.As a result, it was found that the current VR Kohs Block Design Test is very difficult to perform grasping movements, and that it is necessary to construct a highly realistic system. The subject’s gaze and hand movements during the test were generally consistent, indicating that the subject was simultaneously performing grasping and gazing.
