System and method for gesture recognition in three dimensions using stereo imaging and color vision

Abstract: A system and method for recognizing gestures. The method comprises obtaining image data and determining a hand pose estimation. A frontal view of a hand is then produced. The hand is then isolated the background. The resulting image is then classified as a type of gesture. In one embodiment, determining a hand pose estimation comprises performing background subtraction and computing a hand pose estimation based on an arm orientation determination. In another embodiment, a frontal view of a hand is then produced by performing perspective unwarping and scaling. The system that implements the method may be a personal computer with a stereo camera coupled thereto.

Simulated annealing based economic dispatch algorithm

Abstract: This paper develops an economic dispatch algorithm for the determination of the global or near global optimum dispatch solution. The algorithm is based on the simulated annealing technique. In the algorithm, the load balance constraint and the operating limit constraints of the generators are fully accounted for. In the development of the algorithm, transmission losses are first discounted and they are subsequently incorporated in the algorithm through the use of the B-matrix loss formula. The algorithm is demonstrated by its application to a test system. The results determined by the new algorithm are compared to those found by dynamic programming with a zoom feature.

Integrated content guide for interactive selection of content and services on personal computer systems with multiple sources and multiple media presentation

Abstract: A integrated content guide for multiple sources is provided with hyper-text type links to allow for the selection of various programs. The hyper-text links are provided for a transmitted and then stored digital bit stream. This allows for the embedding within the content guide what could be additional commercial information. The embedding may also be as to additional information for other related television or radio shows or the like. Information can be additional television shows, related information or activities on on-line services or automatic telephone ordering of products or services being displayed.

System and method for on-line multimedia access

Abstract: Disclosed is a method and system for providing access to multimedia content on-line which is updated virtually simultaneously with the vendor's update process. By a user accessing a page on the World Wide Web, for example, data (encrypted and unencrypted) and instructions are automatically downloaded to a user's computer system for quick access. Depending upon the user's computer system (LAN or a stand-alone personal computer), "applets" containing data and instructions are stored for immediate access. In a Karaoke application of this invention, where the user desires to access songs which are most popular at a given time, the user accesses a page where a song list and other information is displayed on a display apparatus. When the user clicks on a particular song of the song list, the applet executes an authentication request. If the user is authenticated, the authentication is downloaded as part of the applet containing the desired multimedia content (or separately depending upon the circumstances). According to this invention, an applet includes multimedia elements which further include timing codes and a synchronization function which provides for the synchronization of the delivery of the multimedia elements.

Integrated routing/mapping information system

Abstract: An Integrated Routing/Mapping Information System (IRMIS) links desktop personal computer cartographic applications to one or more handheld organizer, personal digital assistant (PDA) or “palmtop” devices. Such devices may be optionally equipped with, or connected to, portable Global Positioning System (GPS) or equivalent position sensing device. Desktop application facilitates user selection of areas, starts, stops, destinations, maps and/or point and/or route information. It optionally includes supplemental online information, preferably for transfer to the PDA or equivalent device. Users' options include route information, area, and route maps. Maps and related route information are configured with differential detail and levels of magnitude. Used in the field, in conjunction with GPS receiver, the PDA device is configured to display directions, text and map formats, the user's current position, heading, speed, elevation, and so forth. Audible signals identifying the next turn along the user's planned route are also provided. The user can pan across maps and zoom between two or more map scales, levels of detail, or magnitudes. The IRMIS also provides for “automatic zooming,” e.g., to show greater detail or closer detail as the user approaches a destination, or to larger scale and lower resolution to show the user's overall planned route between points of interest. The IRMIS also enables the user to mark or record specific locations and/or log actual travel routes, using GPS position information. These annotated location marks and/or “breadcrumb” or GPS log data can be saved, uploaded, displayed, or otherwise processed on the user's desktop geographic information or cartographic system. The IRMIS application and data may be distributed online and/or in tangible media in limited and advanced manipulation formats.
