  • Patent number: 10652525
    Abstract: Embodiments allow different viewers of a shared display to see different images. Images may have different combinations of polarization and time slices that correspond to filters in glasses worn by the viewers. The images viewed by each of the glasses may be based on the tracked position and orientation of the glasses, so that the images correspond to the user's viewpoint. Different images may be presented to left and right eyes for 3D stereoscopic viewing. The lenses of the glasses may have a filter that selects light of a specific polarization combined with a shutter that passes images during a specific time slice. The polarization filter may select circularly polarized images of a desired orientation and emit linearly polarized images. The shutter may use liquid crystals to twist the linearly polarized images during the desired time slice so that a final linear polarizer passes the image to the viewer.

  • Patent number: 10469834
    Abstract: A stereoscopic display method or system includes an image display panel, object tracking sensors, and a means to create first or left, and second or right stereoscopic images based upon viewpoint location. This allows the user to perceive the viewed 3D stereoscopic image as approximately fixed in space. A first embodiment employs differently filtered colored, stereoscopic images. The first and second differently filtered colored images may be perceived as a 3D stereoscopic image by applying anaglyph glasses. In a second embodiment the method of passively polarized glasses may be applied with the result being a stereoscopic image whose location is approximately fixed in space. A third embodiment employs passively polarized anaglyph glasses. This provides the advantage of allowing two different viewers to see different virtual 3D stereoscopic images whose location remains approximately fixed in space.

  • Publication number: 20140104269
    Abstract: A stereoscopic display system includes an image display panel, a means to polarize light so as to present two patterns of images whose polarization direction differ by approximately 90 degrees, and a means to change the relationship of image to polarization direction pattern. The images may be perceived as a stereoscopic image by viewing them through glasses having polarizing directions which differ by approximately 90 degrees. The display device may be rotated approximately 90 degrees from a first orientation into a second orientation, and the device is able to change left and right image patterns, polarization patterns, or any combination of the two so it may be viewed as a stereoscopic image using glasses whose left and right lenses are of same polarization direction as the glasses needed for the first orientation.
