20080297593 | Rendering for an Interactive 360 Degree Light Field Display - An interactive, autostereoscopic system for displaying an object in 3D includes a mirror configured to spin around a vertical axis when actuated by a motor, a high speed video projector, and a processing system including a graphics card interfaced to the video projector. An anisotropic reflector is bonded onto an inclined surface of the mirror. The video projector projects video signals of the object from the projector onto the inclined surface of the mirror while the mirror is spinning, so that light rays representing the video signals are redirected toward a field of view of a 360 degree range. The processing system renders the redirected light rays so as to interactively generate a horizontal-parallax 3D display of the object. Vertical parallax can be included in the display by adjusting vertically the displayed views of the object, in response to tracking of viewer motion by a tracking system. | 12-04-2008 |
20140267460 | CONTROL OF AMBIENT AND STRAY LIGHTING IN A HEAD MOUNTED DISPLAY - A head mounted display (HMD) for viewing a virtual environment generally include a flat display (FD), lenses for focusing on the FD, and a housing to enclose the FD and lenses. The housing is generally opaque to block out all external light, so the viewer only sees light from the FD. By making a portion or all of the housing translucent or transparent, ambient light and other external light can be seen by the viewer, providing additional visual cues and a larger perceived field of view. Additionally, other people can see light from the FD. The lenses are configured to view the FD and parts of the translucent housing. | 09-18-2014 |
20140268356 | DYNAMIC FIELD OF VIEW THROTTLING AS A MEANS OF IMPROVING USER EXPERIENCE IN HEAD MOUNTED VIRTUAL ENVIRONMENTS - A head-mounted display (HMD) allows a user to view a virtual environment. The HMD displays a field of view to the user. However, the user may experience simulator sickness or motion sickness from viewing the field of view. The HMD is connected to a sensor which can monitor the user. By monitoring the user's physiological state, the user's simulator sickness can be detected or predicted. To reduce the negative effects, the field of view can be throttled. The field of view can also be throttled in order to provide a better user experience even if the user does not experience sickness. | 09-18-2014 |

20110176070 | Rear Projection Imaging System with Image Warping Distortion Correction System and Associated Method - A rear projection imaging system with an image warping distortion correction system using a camera and processing unit to generate a warping map that corrects for image distortion. The warping map is generated in an iterative process by displaying a known pattern on a viewing screen and, through the use of a camera, having a microprocessor determine the location and shape of the pattern on the screen. The microprocessor then compares the displayed image to the original reference image, calculates the distortion effects present in the projection optics, and generates a warping map. | 07-21-2011 |
