Information Transfer Rate Analysis of the Dual Mode Tongue Driven System for the Disabled Person

Abstract

Nowaday's alternative control for computer access and wheeled mobility for the disabled people are considered the most important for today's active lifestyle since they can improve the users' quality of life (QoL) by easing two major limitations: effective communication and independent mobility. In this paper it has been showed that  a new wireless and wearable human computer interface called the dual-mode Tongue Drive System (d TDS), allows people with severe disabilities to use computers more effectively with increased speed, flexibility, usability, and independence through their tongue motion and speech. The effectiveness of the  d TDS is proved by calculating the Information Transfer Rate using the Ns2 simulator.The high Information Transfer Rate proves that the d TDS is better than either unimodal forms based on the tongue motion or speech alone, particularly in completing tasks that require both pointing and text entry.
