摘要： Technologies are described for providing a projected augmented reality system with pose tracking for directing manual processes. A projected augmented reality system includes a video projector, configured to project a dynamically-changing image onto a surface within a work area of an operator, a sensor, and a computer. The computer includes a memory including instructions that when executed cause the computer to obtain three-dimensional pose data using the sensor, determine an output graphical element based on a sequence of three-dimensional pose data over time, and on a current production state, and send an output image based on the output graphical element to the video projector for projection onto the surface.

摘要： The invention provides a liquid crystal projection apparatus where visual control of an image magnified and projected on a screen can be directly carried out. A remote control signal transmitted from a remote controller is converted to a mouse signal or a keyboard signal corresponding to a personal computer connected with a main body. The converted mouse signal or keyboard signal is inputted into the personal computer through a cable. The personal computer generates an image signal on the basis of the inputted signal and sends the image signal to the main body through a cable. Consequently, an image based on the direction of the remote controller is displayed and the image is magnified and projected on the screen.

摘要： An image display system such as an LCD projection display includes an illumination homogenizer and a centrifugal relay lens system. The illumination homogenizer, such as a reflective tunnel homogenizer or integrator, efficiently provides uniform distribution of light over a region matched to the configuration of an LCD, or other type of image source. The centrifugal relay lens system includes, for example, an S-curve aspheric lens surface that functions to increase the illumination distribution toward the edges and corners of the image source relative to the center. The projection system provides illumination with improved uniformity and efficiency while also providing a shortened optical pathway.

摘要： The present invention includes an invertible and orthoscopic LCD projector having a LCD panel for providing display information that is projected toward a display screen to form a display image. In a preferred embodiment, a converging Fresnel lens is positioned to receive the display information from the LCD panel and form a display object corresponding to the display image. The converging Fresnel lens has an optical center offset from the optical center of the LCD panel in an elevation direction and defines a projection optical axis that extends toward the display screen along an elevation angle in the elevation direction. The Fresnel lens is tilted automatically about a tilt axis transverse to the projection optical axis and the elevation direction by an amount proportional to the elevation angle to cooperate with the offset of the Fresnel lens optical center to form an orthoscopic display image.

摘要： A flat panel display screen apparatus with optical junction and removable backlighting assembly. An optical junction is formed between a permanently housed light source within a display assembly and a removable light pipe when inserted into the display assembly. The optical junction is formed from a reflective film attached along the long axis of the light source and extends past a side of the light source to cover a gap between the light source and the light pipe. Another reflective strip is placed along and extends past an edge of the light pipe to bridge the gap. The reflective material is used to reflect stray light into the light pipe. The present invention also includes a display subsystem with a light pipe in a removable door, the removable door assembly adapted for insertion into and removal from the display assembly and comprising a light pipe for optically coupling with the light source for illuminating the flat panel display matrix with the back-light and wherein the light source remains secured within the display assembly upon removal of the removable door assembly so that a power supply line to the light source is not disturbed upon removal of the removable door assembly and further comprising a control circuit responsive to the sensor for turning the light source on when the control signal is at a first state and for turning the light source off when the control signal is at a second state.

摘要： An electro-optical backlighting panel construction for use in portable computer-based systems having direct and projection viewing modes of operation. In the illustrative embodiments of the present invention, the electro-optical backlighting panel is integrated with a LCD display panel, a micropolarization panel, and a touch-screen writing panel to provide several different types of portable computer-based systems including, for example, a portable notebook computer, a computer-driven image display device, and a portable pen-computing device. In general, each of these computer-based systems are capable of selectively displaying color video images on an actively driven display surface, or projecting such video images onto a wall surface or projection screen. These computer-based systems can be easily reconfigured for projection viewing without any sort of physical modification to the LCD display panel assembly. If desired, the these computer-based systems can be used to directly view "spatially-multiplexed" images of 3-D objects or imagery during the direct viewing mode, and when desired these spatially-multiplexed images can be projected onto a wall surface or projection screen during the projection viewing mode. When the spatially-multiplexed images are viewed through electrically-passive polarized glasses, the 3-D object is perceived with stereoscopic depth sensation in either mode of viewing. A portable light projection accessory device is provided for use with the portable computer-based systems of the present invention. In the illustrative embodiments, the portable light projection device has first and second housing portions that are interconnected by a foldable structure that permits the first and second housing portions to be selectively reconfigured for simple trouble-free use during the projection viewing mode of operation, and for compact storage during the direct viewing mode of operation.
