Designing a high accuracy 3D auto stereoscopic eye tracking display, using a common LCD monitor

Designing a high accuracy 3D auto stereoscopic eye tracking display, using a common LCD monitor This paper describes the design and building of a low cost and practical stereoscopic display that does not need to wear special glasses, and uses eye tracking to give a large degree of freedom to viewer (or viewer's) movement while displaying the minimum amount of information. The parallax barrier technique is employed to turn a LCD into an auto-stereoscopic display. The stereo image pair is screened on the usual liquid crystal display simultaneously but in different columns of pixels. Controlling of the display in red-green-blue sub pixels increases the accuracy of light projecting direction to less than 2 degrees without losing too much LCD's resolution and an eye-tracking system determines the correct angle to project the images along the viewer's eye pupils and an image processing system puts the 3D images data in correct R-G-B sub pixels. 1.6 degree of light direction controlling achieved in practice. The 3D monitor is just made by applying some simple optical materials on a usual LCD display with normal resolution. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png 3D Research Springer Journals

Abstract

This paper describes the design and building of a low cost and practical stereoscopic display that does not need to wear special glasses, and uses eye tracking to give a large degree of freedom to viewer (or viewer's) movement while displaying the minimum amount of information. The parallax barrier technique is employed to turn a LCD into an auto-stereoscopic display. The stereo image pair is screened on the usual liquid crystal display simultaneously but in different columns of pixels. Controlling of the display in red-green-blue sub pixels increases the accuracy of light projecting direction to less than 2 degrees without losing too much LCD's resolution and an eye-tracking system determines the correct angle to project the images along the viewer's eye pupils and an image processing system puts the 3D images data in correct R-G-B sub pixels. 1.6 degree of light direction controlling achieved in practice. The 3D monitor is just made by applying some simple optical materials on a usual LCD display with normal resolution.
