Abstract
An electronic device may include a display that displays virtual reality content. Control circuitry may estimate a brightness adaptation state of a user that is wearing the electronic device. The control circuitry may select a tone mapping curve and brightness level for the virtual reality content based on the user's adaptation state. To estimate the user's adaptation state, the control circuitry may gather ambient light information from an ambient light sensor, may gather physiological attributes of the user such as blink rate, pupil size, and eye openness from a camera, and may gather gaze position information from gaze detection circuitry. The control circuitry may optimize the brightness of the display based on the user's current adaptation state, or the control circuitry may shift the brightness of the display away from the user's adaptation level to help guide the adaptation state to the desired level.
