Abstract
A device may determine a first distance between a viewer and a display of a device. The display may include a first parallax barrier including a plurality of parallax barrier clusters. Each of the parallax barrier clusters includes a plurality of parallax barrier elements that are parallel to one another and parallel to the parallax barrier clusters. The device may also determine a second distance between a right eye of the viewer and a left eye of the viewer, and move parallax barrier elements to control spacing between the parallax barrier clusters based on the first distance and the second distance. Furthermore, the device may send, from the display, light rays of a right-eye image of a stereoscopic image and a left-eye image of the stereoscopic image to a right eye of the viewer and a left eye of the viewer, respectively, through the spacing between the parallax barrier clusters.
