<p>An apparatus and method generate a three-dimensional image by presenting, using a stereoscopic display, a representation of a scene comprising one or more objects, tracking a gaze of the user to determine a direction of gaze within the scene, determining depths associated with one or more objects in the scene, and determining which of the objects in the scene are inside and which are outside a comfort zone based at least in part on the direction of gaze of the user and the depths associated with the one or more objects in the scene. In some embodiments, the method includes identifying one or more objects proximate the direction of gaze of the user, determining depths associated with the one or more identified objects, determining a range of depths based at least in part on the depths associated with the one or more identified objects, and establishing the comfort zone based at least in part on the range of depths. In some embodiments, the method includes modifying the presented representation of the scene based on which of the objects are outside the comfort zone. In some embodiments, the method includes focusing the stereoscopic display based at least in part on the determination of which objects are inside the comfort zone, tracking the gaze of the user to determine a second direction of gaze within the scene different from the direction of gaze within the scene, re-determining depths associated with one or more objects in the scene, re-determining which of the objects in the scene are inside and which are outside the comfort zone based at least in part on the second direction of gaze of the user and the re-determined depths associated with the one or more objects in the scene, and re-focusing the stereoscopic display based at least in part on the determination of which objects are inside the comfort zone.</p> |
