Problems solved by technology

This disparity between competing depth cues can result in viewer fatigue and discomfort, especially over an extended period of time, and can potentially interfere with the benefits of using a stereoscopic display.
The potential for fatigue, including eyestrain, headaches or other discomfort, is generally believed to be increased as the degree of mismatch increases and can potentially interfere with the benefits of using a stereoscopic display.

Embodiment Construction

[0023]The following detailed description is merely illustrative in nature and is not intended to limit the embodiments of the subject matter or the application and uses of such embodiments. Any implementation described herein as exemplary is not necessarily to be construed as preferred or advantageous over other implementations. Furthermore, there is no intention to be bound by any expressed or implied theory presented in the preceding technical field, background, brief summary, or the following detailed description.

[0024]A stereoscopic display system (three dimensional (3D)) provides two images of the same object taken from two perspectives that when viewed by two eyes are interpreted as an image having depth (depth perception). The stereoscopic display system described herein provides enhanced usability by users of the display, especially for applications which rely on extended duration and / or critical information, such as avionics, medical, engineering / industrial, or military app...

Abstract

A variable focus stereoscopic display system includes first and second lenses positioned between a viewer's eyes and a stereoscopic display that alters the distance to the focus plane of the viewer based on the vergence of the viewer's eyes while viewing the stereoscopic display.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This is a Continuation of U.S. patent application Ser. No. 13 / 077,197, filed Mar. 31, 2011.TECHNICAL FIELD[0002]The exemplary embodiments described herein generally relate to information displays and more particularly to stereoscopic displays.BACKGROUND[0003]Three dimensional (3D) displays are becoming increasingly popular. Presently, many 3D displays implement stereoscopic techniques to generate a 3D visual display to a user. Such displays, which may be referred to as stereoscopic 3D displays, rely on the well known stereoscopic imaging technique for creating the illusion of depth in an image. As is generally known, stereoscopy is a method of creating a 3D image from a pair of two dimensional (2D) images, in which each of the 2D images preferably represents the same object or image from a slightly different perspective, such as a right eye perspective and a left eye perspective.[0004]Referring to FIG. 1, a typical prior art stereoscopic ...
