AI summary

A virtual vision test can be conducted to assess visual field loss using interactive visual maps in a virtual reality (VR) environment. The test can be conducted using an electronic device with a head-mounted display (HMD) and a camera. The device can generate and render a VR user interface corresponding to a three-dimensional virtual environment. The device can simulate interactive visual map scenarios and, in real-time, track gaze direction and responses to one or more stimuli appearing at various locations within the visual field. The device can then analyze these responses to map out areas of visual field loss.
