    Abstract: In one implementation, a first captured image is accessed. The first captured image includes (1) a first display produced at a first point in time, and (2) a user interacting with the first display and not part of the first display. A second captured image is accessed. The second captured image includes (1) a second display produced at a second point in time, and (2) the user interacting with the second display and not part of the second display. The first captured image and the second captured image are compared. The motion of the user is determined based on a result of the comparing of the first captured image and the second captured image. The determined motion of the user is related to a portion of one or more of the first and second captured images.

    Abstract: A multiple camera tracking system for interfacing with an application program running on a computer is provided. The tracking system includes two or more video 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: Enhanced multi-touch detection, in which a graphical user interface for an application is projected onto a surface, and electromagnetic radiation is emitted. The electromagnetic radiation is collectively emitted by an array defining a layer aligned parallel with the surface and overlapping at least a region of the surface onto which the graphical user interface is projected. Electromagnetic radiation is detected that reflects off of an object interrupting the defined layer where the defined layer overlaps the region of the surface onto which the graphical user interface is projected, and indicating a position of the object is output.

    Abstract: A method is described for determining a description of motion of a moving mobile camera to determine a user input to an application. The method may involve capturing a series of images from a moving mobile camera and comparing stationary features present in the series of images. Optical flow analysis may be performed on the series of images to determine a description of motion of the moving mobile camera. Based on the determined motion, a user input to an application may be determined and the application may respond to the user input, for example, by updating a user interface of the application.
