Average processors now run at over > 1.5GHz, while top-of-the-line chips run at 3GHz.

Microsoft Research, for example, has developed a > prototype application called GWindows, with which a person can scroll through files > or move windows though a combination of voice commands and hand gestures, said Andy > Wilson, the project's designer. > > With GWindows, a video camera mounted on a television monitor follows moving > objects, such as a hand or pointer, that come within 20 inches of the screen. The > application interprets any hand movements (or pointer gestures) as computer > commands: placing a finger over a window and then moving a finger left will move the > window left, for example. If a voice command such as "scroll" is given, the computer > will combine the finger and voice commands and scroll down. No special gloves are > needed. > > Microsoft's prototype application works better than a simple voice recognition > system because the gestures improve accuracy, according to Wilson, who has > demonstrated that the computer can follow voice commands in a crowded room filled > with multiple conversations and lots of interference. > > Such visual signal software relies in part on Bayesian mathematics, which is > influencing other interface and artificial intelligence projects at Microsoft. In > Bayesian maths, computers essentially rely on statistics. If a computer "sees" a > sweeping hand gesture toward the left a number of times, it will consistently > interpret that gesture as a command to move a file toward the left. > > Intel has other visual applications to AVSR in the works. The tech giant is looking > into an application that uses cameras to monitor hospital patients for risk of > strokes and into software that uses a security camera feed to detect potential > criminals in a parking lot. The underlying principles of these programs are the > same: the computer sends an alert when it sees something unusual -- a slowing in a > patient's gait or a person going from car to car instead of into the mall -- in its > video stream. > > The work on these applications and the development of AVSR is taking place at > Intel's China Research Center in Beijing. > > In other Intel software research news, the company has released a test version of a > technical library for building Bayesian networks, said Gary Bradski, a senior > researcher in Intel's Microprocessor Research Labs who helped create the OpenCV > library. A final version of the technical library, called the Probability Network > Library, will come out by the end of the year, he said. > > > -- * 9-11, John Deutch, Mitre Corp., Prince Ahmed bin Salman bin Abdul Aziz of Saudi Arabia, and the NRO http://lists.riseup.net/www/arc/whistleblowers/2003-10/msg00024.html -- ______________________________________________ Check out the latest SMS services @ http://www.linuxmail.org This allows you to send and receive SMS through your mailbox.
