True Three-Dimensional (3-D) Display with Focus Cues

Introduction When viewing a real scene, not everything in the scene is in focus at any given time. Instead the individual viewing the scene accommodates (adjusts the focus of the eye) to bring objects at various distances into focus. Current stereographic displays tend to cause profound eye fatigue often accompanied by headache. The eye fatigue is likely in part due to the result of a mismatch between the depth information provided by accommodation and that provided by vergence (the extent to which a viewer’s eyes are pointed ahead in a parallel or angled in to look at a close target.)
Technology description Researchers at the University of Washington have developed inventions, utilizing hardware and software processes that create visual displays that mimic 3-D viewing more naturally than current stereographic displays. The human eye captures 2-D images on the retina and the human mind perceives distance or depth by using the many available depth cues. The cues are be generated in hardware using wavefront shaping deformable membrane mirrors. In addition, software cues, such as blurring, relative size, occlusion, etc., are tested for triggering appropriate responses in electronic 3-D displays. Our prototype electronic display that allow for both accommodation and vergence which we call "true 3D" displays since it allows the viewer to see in 3-D. It is anticipated that these more natural true 3-D displays will reduce viewer's eye fatigue and make a more compelling visual experience. Business opportunity Potential markets include computer gaming, virtual reality, virtual retinal displays, etc. Stage of development Proof of concept, and prototype developed. Intellectual property position The UW has applied for patent protection on the True Three-Dimensional (3-D)
Display with Focus Cues. For more information on this technology contact:
