One of the Siemens Westinghouse winners designed a glove that interprets the sign language alphabet. As with voice recognition, you train the device and software to recognize your hand movements. Although it is limited to the alphabet, you can train it to recognize a specific motion as representing a word. Deaf people interviewed for the article agree that it is an interesting concept but that it is of limited use since most signing does not use the alphabet. Regardless, it is an impressive idea from an 18 year old. Inventor Ryan Patterson plans to add a voice recognition component so that the screen can show the results of both signing and speaking which will allow two way communication.
