Abstract
According to an example, at least one user in proximity to a display is detected with a camera. A primary user and eye gaze are determined. The location of a secondary user relative to the display is calculated, and an active screen area and an inactive screen area based on the eye gaze are determined. A first angle and a first brightness for the active screen area and a second angle and a second brightness for the inactive screen area based on the location of the secondary user are calculated, and focus area boundaries for the active screen area based on the location of the secondary user are calculated. The first angle, the first brightness, and the focus area boundaries are applied to the active screen area, and the second angle and the second brightness are applied to the inactive screen area.
