Abstract:
1. A sign language translation system for converting sign language to text, the system comprising: a 3-axis accelerometer sensor and four 2-axis accelerometer sensors, wherein the 3-axis accelerometer sensor is disposed at a finger tip of a finger of a hand of a person using the sign language and each of the 2-axis accelerometer sensors is selectively disposed at a finger tip of one of other fingers of the hand; RFID transponders selectively disposed in pre-determined regions of an upper body or clothing of the person, said regions located proximate to or along a centerline of an anterior side of the upper body; a RFID reader disposed on a finger or a palm of the hand and configured for acquiring first data from the RFID transponders; a multiplexer multiplexing second data acquired from the sensors and the first data into a sequence of data packets; and a controller transmitting the data packet to a computer converting the data packets to the text; whereby the computer is configured to detect in the data packets hand position of the person using the first data as a reference point and interpolating the hand position using the second data.
