Abstract
A system and method for generating a corrected input to a display to offset glare is provided. The system determines a location of a user's head and calculates a reflection vector based on a head vector from a device to a point on the user's head. The system identifies light sources using a camera and determines display pixels on a display of the device affected by the reflection of the light sources based on head detection and locations of the light sources. The system dynamically adjusts pixel brightness to account for a detected glare, thus improving the user's experience operating the UI.
