A design of a new electro tactile beat module

Abstract

The use of two or more vibration motors in consumer electronic devices can be a solution to haptically simulate a variety of graphical objects. When there is no rendering method to haptically simulate target objects, the manipulation feeling can be missing and the use of motors can be more insecure. One of the several haptic rendering methods is to use beat vibration which is interference pattern between two or more vibrations of slightly different frequencies from two or more vibration motors. However, the strategy of beat vibration brought a new issue for handling multiple vibration motors. This paper presents a new electro tactile beat module which does not need any mechanical vibration motors.
