Patent number: 10652525Abstract: 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.Type: GrantFiled: May 29, 2018Date of Patent: May 12, 2020Assignee: 3DI LLCInventor: David Paul Woods

Patent number: 10469834Abstract: 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.Type: GrantFiled: January 30, 2018Date of Patent: November 5, 2019Assignee: 3DI LLCInventor: David Paul Woods

Patent number: 10116914Abstract: A stereoscopic display system includes an image display panel, viewpoint position sensors, and a means to create first or left and second or right stereoscopic images corrected for parallax. This allows for multiple viewpoints to perceive the viewed 3D stereoscopic image as approximately fixed in space. In one embodiment, the first and second images may be perceived as a 3D stereoscopic image by applying shutter glasses. In another embodiment, the first and second images may be perceived as a 3D auto stereoscopic image by applying configurable louvers or light guiding layers. In this embodiment, the display system utilizes information from the position sensors to optimize electronically configurable louvers. This allows for large displays to be seen from multiple viewpoints. The virtual 3D stereoscopic object images, being virtually fixed in space may be interacted with by the user or users in much the same way 2D objects are manipulated by applying a touch screen.Type: GrantFiled: December 15, 2013Date of Patent: October 30, 2018Assignee: 3DI LLCInventor: David Woods

Patent number: 9986228Abstract: Embodiments present different images to multiple viewers of a shared display using glasses with lenses that transmit only selected images from the display. 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 also be presented to left and right eyes for 3D stereoscopic viewing. The position and orientation of the lenses of the glasses may be tracked by analyzing images from one or more cameras observing the glasses. Glasses may have distinctive geometric shapes or features, such as circular lenses or rims, or recognizable blobs or patterns, to facilitate tracking. The lenses of the glasses may combine multiple barriers such as anaglyph filters, polarizing filters, and shutters, to select images from the display. Glasses may also be used as pointing devices to select and manipulate 3D objects.Type: GrantFiled: March 16, 2017Date of Patent: May 29, 2018Assignee: 3DI LLCInventor: David Woods
