Systems, methods, and computer-readable media are provided for controlling a stereoscopic display device to improve perception of stereoscopic visual content. One method includes displaying a first item of visual content through a first portion of a polarizing filter, and displaying, through the first portion and/or a second portion of the polarizing filter, a first message based on whether the first item of visual content is to be visible by a first or second eye of the observer. Another method includes capturing an image of an observer, determining a position of the observer based on the captured image, comparing the determined position to a predetermined position criterion, and causing a message based on a result of the comparing to be provided to the observer. In another method, the display device is repositioned based on a result of the comparing.
