Abstract
This paper describes an elegant method for recognizing the pattern of alphabets and distinguishing different points and their orientation based on two ultrasonic distance sensors. Sequence of line segments, formed by a set of different points, is determined by chain code algorithm. The result shows the simplicity of the system utilizing ultrasonic sensors, which can be developed into a new type of keypad.
