Virtual reality compensation for visual impairment
A recently granted patent (Publication Number: US12001605B2) outlines a method for adjusting images displayed in a virtual reality environment based on the visual impairments of the user wearing a head-mounted display (HMD). The method involves rendering an initial image with unimpaired vision quality, identifying visual impairments through user inputs such as eye positions, movements, and focal points, and making visual adjustments to the HMD accordingly. These adjustments can include altering image zoom, perspective, brightness, sharpness, and contrast, as well as modifying the optical lenses of the HMD by changing their position, shape, curvature, or index of refraction.
Furthermore, the patent describes a computer system equipped with sensors and computing systems associated with an HMD, along with computer-readable storage media containing software to implement the method. This system can render adjusted images in response to user inputs, providing a personalized and optimized visual experience in virtual reality environments. The patent also covers the use of audio commands and body movements as user inputs for identifying visual impairments and making corresponding adjustments to the displayed images. Overall, this technology aims to enhance the virtual reality experience for users with visual impairments by dynamically adapting the visual content to suit their specific needs and preferences.
