7366645 Method of recognition of human motion, vector sequences and speech  
A method for recognition of an input human motion as being the most similar to one model human motion out of a collection of stored model human motions. In the preferred method, both the input and...
7355593 Pointer tracking across multiple overlapping coordinate input sub-regions defining a generally contiguous input region  
A touch system comprises overlapping coordinate input sub-regions defining a generally contiguous input surface. Each coordinate input sub-region generates pointer coordinate data in response to...
7305630 Ink gestures  
A system and process for capturing and implementing handwritten gestures is described. A user may use gestures to quickly command a pen-based input device to perform operations. Using the described...
7256772 Auto-aligning touch system and method  
A touch system includes a touch surface on which an image is, displayed and at least one camera acquiring images of the touch surface. A pointer contact data generator generates pointer position...
7236162 Passive touch system and method of detecting user input  
A passive touch system includes a passive touch surface and at least two cameras associated with the touch surface. The at least two cameras acquire images of the touch surface from different...
7232986 Apparatus for detecting a pointer within a region of interest  
An apparatus for detecting a pointer within a region of interest includes at least one pair of imaging devices. The imaging devices have overlapping fields of view encompassing the region of...
7224830 Gesture detection from digital video images  
Human gestures are detected and/or tracked from a pair of digital video images. The pair of images may be used to provide a set of observation vectors that provide a three dimensional position of a...
7200266 Method and apparatus for automated video activity analysis  
The invention is a new method and apparatus that can be used to detect, recognize, and analyze people or other objects in security checkpoints, public-places, parking lots, or in similar...
7184030 Synchronization of cameras in camera-based touch system to enhance position determination of fast moving objects  
A camera-based touch system includes at least one pair of cameras having overlapping fields of view and a touch surface encompassed within the overlapping fields of view across which a pointer is...
7068843 Method for extracting and matching gesture features of image  
A method for extracting and matching gesture features of image is disclosed. An input gesture image is captured, and then a closed curve formed by a binary contour image of the gesture image is...
7058204 Multiple camera control system  
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...
7000200 Gesture recognition system recognizing gestures within a specified timing  
Gesture recognition in which timing data is used to temporally segment video data into video clips. The timing data can be beat data extracted from an audio signal.
