There is provided a display device capable of extending the range of its application by enhancing the designability and the diversity of the display manner and by improving visual effects. The display device includes: a projector configured to project light to display information in the form of a projection image; a screen having a display surface through which light projected by the projector passes to form a projection image thereon; and a controller configured to control the projector. The display surface has a non-planar shape.

There is provided a gaming machine capable of providing diverse type of image representation. The gaming machine 1 includes: a screen unit 10040 whose surface at least partially includes curved portions 10042; and a projector 10020 accommodated inside a casing 2, which is configured to project light to the screen unit 10040. Light projected by the projector 10020 is incident on a back surface side of the screen unit 10040 from the inside of the casing 2. The screen unit 10040 lets the light incident on the back surface side of the screen unit 10040 pass the screen unit 10040, thereby enabling displaying of an image on the front surface side of the screen unit 10040 positioned on the surface of the casing 2.

A synthetic image display device includes: a beam projector configured to project a first image; a screen on which the first image projected from the beam projector is formed; and a transparent display panel disposed so as to face the screen and configured to display a second image to be combined and viewed with the first image formed on the screen, the transparent display panel being formed with a pinhole for penetration of light in each pixel so that the first image penetrates and is viewed through the transparent display panel.

The present invention provides a projection display system having a three-dimensional convex display surface, such as a spherical or hemispherical display surface, in which the condenser lens before the optical modulating device may have a reduced focal distance for focusing the light more tightly on the optical modulating device, so as to illuminate only the center portion of the optical modulating device. Alternatively, the projection display system may have a square light pipe or any shaped light pipe in the optics in order concentrate the light to illuminate only a center portion of the optical modulating device or devices. The light pipe may be at least one of a round shape, pentagonal shape, a hexagonal shape, an octagonal shape, etc.

A system, method, and device for simulating an emission signature, which contains representative intensity, temporal, and spectral emission profiles of a weapon system or weapon platform for the purpose of testing an optical detection device. A projection system optically projects the emission signature. A projection screen is provided that has a concave curvature. The concave curvature possesses a first focal point and a second focal point. Any light emanating from the second focal toward the projection screen is reflected by the projection screen toward the first focal point. The projection system is positioned at the second focal point and the optical detection system is positioned at the first focal point. In this manner, the emission signature projected by the projector system is redirected to the optical detection system.

A lensed display system includes a projector configured to project an image. The lensed display system includes a lens formed of a glass or crystalline material. The lens includes a first surface, wherein at least a portion of the first surface includes a coating that is configured to display the projected image. The lens includes a second surface, wherein the second surface comprises a transparent curved surface that is configured to face toward a user and to enable the user to view the image projected onto the coating through the transparent curved surface.

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 an 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.

A holographic three dimensional imaging projecting medical apparatus is provided, including: a three dimensional imaging device, having a projecting mechanism and an image forming mechanism, the projecting mechanism including a housing and a projecting unit, the projecting unit projecting a plurality of projected images through the housing to the image forming mechanism, to form a three dimensional image within an image forming space of the image forming mechanism, the housing having a plurality of reflection portions, each of the plurality of reflection portions having a through hole and a plurality of light reflecting sheets disposed around the through hole, the projecting unit attached to the housing; a motion detector, detecting an operating gesture and generating a control signal corresponding to the operating gesture; and a processor, receiving the control signal and controlling the three dimensional image according to the control signal.

A device receives information to be projected from within and onto a mannequin, and receives instructions associated with projection of the information from within and onto the mannequin. A mirror and a projector are provided within the mannequin, and the projector is in optical communication with the mirror. The device causes, based on the instructions, the mirror to be moved from a first location to a second location, the mirror to be rotated from a first position to a second position, the projector to be moved from a third location to a fourth location, or the projector to be rotated from a third position to a fourth position. The device provides the information to the projector, and causes the projector to provide the information at a portion of the mannequin via the mirror, wherein the information is projected from within and onto the mannequin at the portion.
