Claims9
A method of translating sign language, the method comprising
- receiving a series of images from a camera pertaining to a motion of a provider's hand, finger, fingertip, and/or arm corresponding to a first unit of sign language information;
- identifying from the images pixels corresponding to the hand, finger, fingertip and/or arm;
- tracking motion of the hand, finger, fingertips and/or arm based on the pixels in the images;
- processing the images to correlate the motion of the first unit of sign language information to a stored unit of sign language information of a different sign language type stored on a computer readable medium;
- and
- outputting the stored unit of information of a different sign language type to a receiver, wherein said outputting comprises providing image information comprising motion of a hand, finger, fingertip and/or arm pertaining to sign language of a type different than said first unit of information.
A system for translating sign language, the system comprising a camera in communication with a computer, the computer comprising a computer readable media and being programmed to receive video images of a unit of sign language motion, identifying from the images pixels corresponding to the hand, finger, fingertip and/or arm;
- tracking motion of the hand, finger, fingertips and/or arm based on the pixels in the images;
- and correlating the sign language motion to unit of information stored on the computer readable media;
- and an output device for outputting an output unit of information, wherein the computer is programmed to output the output unit of information via said output device, and wherein said output unit of information comprises providing image information comprising motion of a hand, finger, fingertip, and/or arm pertaining to sign language of a type different than said unit of sign language motion.
