100‐3: <i>Late‐News Paper:</i> Subjective and Objective Eye Tracking Test Results of Commerical VR Products

We conducted spatial accuracy tests on virtual reality products with eye‐tracking capabilities, and provided two test methods, a subjective eye‐tracking test with volunteers and an objective eyetracking test using a high‐precision human eye simulation device. By comparing the test results, we found that the objective spatial accuracy test better reflects the performance of the eye tracking system, and that the high‐precision human eye simulation device can provide a strict true value of the eye gaze direction and is a stable system that simulates the real human eye gaze. In addition, the spatial accuracy of eye tracking is more superior under the condition of appropriate eye relief distance, and the relative position of the eye tracking module to the eyeball also affects the spatial distribution of the gaze point and thus the magnitude of the spatial accuracy.
