Different Haptic Senses with Multiple Vibration Motors

Abstract

The aim of this work is to generate different haptic senses by using distinct vibration motors, which are different from each other, simultaneously. For this purpose, Eccentric Rotary Mass (ERM) and Linear Resonant Actuator (LRA) are used for generating haptic signals which are easily discriminated by a user by touching the surface. The vibration signals are created by changing the parameters of ERM and LRA such as frequency, amplitude, modulation, duration…etc. and each represents corresponding message.
