METHODS AND SYSTEMS FOR TRACKING EYE MOVEMENT IN VISION TESTS IN VIRTUAL ENVIRONMENTS

Original (Chinese)

This application is directed to tracking eye positions in a vision test in a virtual reality (VR) environment. An electronic device includes a head-mounted display (HMD) and a camera. The electronic device executes a user application configured to enable a virtual vision test, and generates a VR user interface corresponding to a three-dimensional (3D) virtual environment. The electronic device focuses the camera on an eye area of a user wearing the electronic device, and displays, on the user interface, a visual stimulus corresponding to the virtual vision test. While displaying the visual stimulus, in real time, the electronic device captures a sequence of eye images using the camera, determines eye movement information including a temporal sequence of eyeball positions based on the sequence of eye images, and compares the visual stimulus and the eye movement information to determine an eye health condition.
