USER INPUT DEVICE USING BIO RADAR AND TILT SENSOR

摘要

A character inputting apparatus by using a bio radar and a tilt sensor which a special key such as a frequently used direction key is inputted through the tilt sensor is provided to allow a user to input character in a method the same as the existing keyboard usage method by recognizing character information by using the bio radar. A bio radar(400) senses the finger position of a user. A tilt sensor(401) senses the slope of the hand of the user. A microprocessor processes the signal which is received from the bio radar and the tilt sensor and produces the final input information of the user. A wireless communications module(404) transmits the final input information of the user to the mobile device or the wearable terminal.
