    Abstract: Hover detection technology, in which an image is captured from a camera while an illumination source is illuminating an area in front of a display surface and the image captured by the camera is analyzed to detect an object within an anticipated input region based on illumination of the illumination source. User input is determined based on the object detected within the anticipated input region and an application is controlled based on the determined user input.

    Abstract: An element is initially displayed on an interactive touch-screen display device with an initial orientation relative to the interactive touch-screen display device. One or more images of a user of the interactive touch-screen display device are captured. The user is determined to be interacting with the element displayed on the interactive touch-screen display device. In addition, an orientation of the user relative to the interactive touch-screen display device is determined based on at least one captured image of the user of the interactive touch-screen display device. Thereafter, in response to determining that the user is interacting with the displayed element, the initial orientation of the displayed element relative to the interactive touch-screen display device is automatically adjusted based on the determined orientation of the user relative to the interactive touch-screen display device.

    Abstract: Enhanced handheld screen-sensing pointing, in which a handheld device captures a camera image of one or more fiducials rendered by a display device, and a position or an angle of the one or more fiducials in the captured camera image is determined. A position on the display device that the handheld device is aimed towards is determined based at least on the determined position or angle of the one or more fiducials in the camera image, and an application is controlled based on the determined position on the display device.

    Abstract: A multiple camera tracking system for interfacing with an application program is provided. The tracking system includes multiple cameras arranged to provide different viewpoints of a region of interest, and are operable to produce a series of video images. A processor is operable to receive the series of video images and detect objects appearing in the region of interest. The processor executes a process to generate a background data set from the video images, generate an image data set for each received video image, compare each image data set to the background data set to produce a difference map for each image data set, detect a relative position of an object of interest within each difference map, and produce an absolute position of the object of interest from the relative positions of the object of interest and map the absolute position to a position indicator associated with the application program.

    Abstract: A camera is used to detect a position and/or orientation of an object such as a user's finger as an approach for providing user input, for example to scroll through data, control a cursor position, and provide input to control a video game based on a position of a user's finger. Input may be provided to a handheld device, including, for example, cell phones, video games systems, portable music (MP3) players, portable video players, personal data assistants (PDAs), audio/video equipment remote controls, and consumer digital cameras, or other types of devices.
