Publication number: 20120206337Abstract: 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.Type: ApplicationFiled: February 1, 2012Publication date: August 16, 2012Applicant: QUALCOMM IncorporatedInventors: Evan Hildreth, Francis Macdougall

Publication number: 20100066667Abstract: 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.Type: ApplicationFiled: September 14, 2009Publication date: March 18, 2010Applicant: GESTURETEK, INC.Inventors: Francis MacDougall, Evan Hildreth
