Design and implementation of low cost multi threaded haptic feedback device

Abstract

This paper presents a novel approach to haptics, as a proof of concept designed a haptic feedback device seven times cheaper than OS (Operating System) based microcontroller. This paper addresses problem in two domains first a haptic feedback device and second multithreaded system on a low-end microcontrollers like PIC (Peripheral Interface Controller). The concept of implementing multithreading system on PIC is a novel approach that is not implemented in past. The circuit of device is simulated on Proteus Design Suite and experimentally verified on actual device after fabrication. Furthermore a protocol is designed to transfer data between host and device known as haptic sequence. This device can be connected to computers and smart phones using USB (Universal Serial Bus) or Bluetooth. It has large number of applications from assistive technologies to medical purposes.
