An image display apparatus according to an embodiment of the present technology includes a display surface, an image display section, an acquisition section, and a light-shielding section. The display surface has transparency. The image display section displays a display image on the display surface. The acquisition section acquires eye information regarding an eye of a user. The light-shielding section forms, according to the acquired eye information and information regarding the display image, a light-shielding region in a region corresponding to a display region of the display image. This makes it possible to improve the visibility of the display image.

The present invention relates to display systems that use materials made from various arrangements of lenses and other optical materials. Careful design and use of these materials can be used to achieve display systems with many desirable visual effects having applicability in image and video displays, virtual reality, immersive environments, as well as in architecture, art, entertainment, and interactive systems.

An apparatus for displaying a three-dimensional image comprises: a light field generating unit (110), which is configured to receive an incident light beam (112) and generate a three-dimensional light field; and an image revealing medium (120), which is arranged to receive the three-dimensional light field generated by the light field generating unit (110), wherein the image revealing medium (120) comprises a fluid with bubbles or particles suspended in the fluid, wherein the bubbles or particles have a size in the range of 40-500 nm.

Information indicating a shape of a screen, a shape of a viewing area and a relative positional relationship between the viewing area and the screen is acquired. A shared area in which a three-dimensional image presented by a three-dimensional display is to be arranged in order to be observed from any position in the viewing area is created based on the acquired information. Based on the acquired information, a specific area in which a three-dimensional image presented by the three-dimensional display is to be arranged in order to be observed from a specific position in the viewing area is created. The data indicating the created shared area and the data indicating the specific area are generated.

One aspect of the invention provides a system for dynamically repositioning a portion of a screen. The system includes: at least one knife moveable between a first position and a second position; a hook moveable between an open position in which the hook is disengaged from the at least one knife and a closed position in which the hook is removably engaged with the at least one knife; a node located on a back surface of the screen; and a linkage between the node and a distal end of the hook. When the hook is in the closed position and the at least one knife is moved from the first position to the second position, the linkage pulls the node causing the portion of the screen centered around the node to be moved distally away from a remaining portion of the screen.

A three-dimensional (3-D) projection system includes a projector configured to output a projection of light to simulate a 3-D object, an opaque surface configured to receive the projection of light to simulate a portion of the 3-D object on the opaque surface, and a translucent scrim disposed at a boundary of the opaque surface and configured to receive the projection of light to simulate an extension of the 3-D object away from and beyond the boundary of the opaque surface.

There is provided an information generation method including, identifying a correspondence relationship between a projector coordinate system and a camera coordinate system, receiving a first operation of designating a first display area representing an arrangement destination of a projection object which is projected on a projection target in a first coordinate system which is one of the camera coordinate system or the projector coordinate system, transforming the first display area into a second display area representing an arrangement destination of the projection object in a second coordinate system which is another of the camera coordinate system or the projector coordinate system based on the correspondence relationship, receiving a second operation of changing at least one of a shape or a position of the second display area, and generating information for changing at least one of a shape or a position of the projection object in accordance with the second operation.

Systems and methods for detecting gestures of a swimmer in an aquatic environment such as a flume pool. In one embodiment, a pool system includes a set of cameras, one of which is overhead camera positioned above the water in the pool to capture images of a swimmer. The system also includes computer processors, such as a GPU, CPU, and game engine which implement a computer vision platform. The processors are configured to receive images from the cameras, determine the swimmer's body position from the images, detect a defined gesture in the swimmer's body position, and in response to detecting the defined gesture, invoking a corresponding control operation of the flume pool, such as controlling water flow through the pool or updating an interface display which is projected onto the interior surfaces of the pool.

Systems and methods for providing a distortion-free pool-surface display beneath a swimmer. In one embodiment, projectors are positioned below a water level at opposite walls of a pool, and are configured to project images to a display surface at the bottom of the pool beneath a swimmer. A camera is used to view images projected by the projectors and to provide corresponding image data to an image correction platform on a graphics processing unit (GPU). The image correction platform identifies distortions in the images, generates image corrections that counter the identified distortions, and applies the corrections to subsequently projected images. The image correction platform also generates image adjustment that cause overlapping portions of the projected images to match seamlessly. The projected images may provide immersive experiences, coaching/training interfaces or other interactive displays.
