Abstract: A visual system includes one or more units, where each unit is a displaying unit or a video camera, or a combination of both, and each unit has a receiver. The unit has a transmitter which starts transmitting infrequent, short repetitive bursts if no bursts are received by the receiver; and otherwise transmits a delayed short burst synchronized to the infrequent, short repetitive bursts by the transmitter, in order to synchronize all units in the visual system to each other, while the infrequent, short repetitive bursts will not interfere nor will be interfered by the general use of remote controllers for other purposes.

Abstract: A projection system includes a light emitting apparatus that emits detection light to a detection area for detecting indication positions of indicators, and a projector that detects the indication positions of the indicators in the detection area. The projector includes an imaging portion that captures an image of the detection area, and a position detection portion that detects at least one of an image of light generated by the indicator and an image of the detection light reflected on the indicator from data of a captured image of the imaging portion, and discriminates and detects the indication positions of the indicator and the indicator based on light emission timings of the indicator and the light emitting apparatus.

Abstract: A method, system and apparatus is provided for controlling and interacting within an interaction volume and/or surface of a computer. The method, apparatus and system is optionally employed together with, or even be integrated into, data projectors of all types and its fixtures/stands, and used together with flat screens (LCD, plasma, OLED, rear-projection screen and so forth) to render such display systems interactive. The apparatus incorporates a camera covering the interaction area from either a very short distance or from a larger distance to determine the lateral positions (X, Y) and even capturing the pose of the finger(s), hand(s) or other interacting object(s), which optionally include the determination of “touch” and “hovering”.

Abstract: An interactive projector includes an imaging section adapted to take an image of a projected screen, a correlation value calculation section adapted to calculate a correlation value between each of template images used to detect the pointing element and a taken image taken by the imaging section and including the pointing element to generate a first correlation value for each of the template images, a correlation value map generation section adapted to generate a correlation value map representing the correlation values between the plurality of template images and the taken image based on the plurality of first correlation values generated for the respective template images, and a pointing element detection section adapted to extract a high correlation value area in the correlation value map, and calculate a centroid of the correlation values in the high correlation value area to thereby detect a tip position of the pointing element.

Abstract: An apparatus, system and method controls and interacts within an interaction volume within a height over the coordinate plane of a computer such as a computer screen, interactive whiteboard, horizontal interaction surface, video/web-conference system, document camera, rear-projection screen, digital signage surface, television screen or gaming device, to provide pointing, hovering, selecting, tapping, gesturing, scaling, drawing, writing and erasing, using one or more interacting objects, for example, fingers, hands, feet, and other objects, for example, pens, brushes, wipers and even more specialized tools. The apparatus and method be used together with, or even be integrated into, data projectors of all types and its fixtures/stands, and used together with flat screens to render display systems interactive.

Abstract: A position detection apparatus includes: an imaging portion that captures an image of a detection area for detecting indication positions of indicators; and an indicator detecting portion that detects the indication positions of the indicators based on operation image data captured by the imaging portion when indication operations by the indicators are performed in the detection area and background image data captured by the imaging portion when the indication operations by the indicators are not performed.
