INTRODUCTION

THE   TONGUE DRIVE SYSTEM IS A NEW INDUCTIVE TONGUE-COMPUTER INTERFACE TECHNOLOGY.

SPECIALLY DESIGNED FOR PEOPLE, PEOPLE WHO GOT  SPINAL CORD INJURIES

TONGUE DRIVE SYSEM IS MAINLY DESIGNED TO CONTROL ENVIROMENT

 

WHY WE USE TONGUE

THE TONGUE TO CONTROL THE SYSTEM BECAUSE UNLIKE THE FEET AND THE HANDS, WHICH ARE CONNECTED BY BRAIN THROUGH SPINALCORD.

THE TONGUE AND THE BRAIN HAS A DIRECT CONNECTION THROUGH CRANIAL NERVE.

TONGUE MOVEMENTS ARE ALSO FAST, ACCURATE AND DO NOT REQUIRE MUCH THINKING, CONCENTRATION OR EFFORT

DESIGN OF TONGUE DRIVE

 A TINY MAGNET, ONLY A SIZE OF A GRAIN OR RICE, IS ATTACHED TO AN INDIVIDUAL'S TONGUE USING ADHESIVE THE MAGNET ATTACHED TO THE TONGUE ARE SPOTTED BY A NUMBER OF MAGNETIC FIELD SENSORS INSTALLED ON A HEADSET WORN OUTSIDE

EARLIER VERSION

WORKING PRINCIPLE

MOVEMENT OF THE MAGNETIC TRACER ATTACHED TO THE TONGUE IS DETECTED BY AN ARRAY OF  MAGNETIC FIELD SENSORS.

THE SENSOR OUTPUT SIGNALS ARE WIRELESSLY TRANSMITTED TO A  PORTABLECOMPUTER, WHICH CAN BE CARRIED ON THE USER'S CLOTHING OR WHEELCHAIR.

EARLIER VERSION

ACCORDING TO TOUNG MOMENT CONDITION IS TAKE AN LEFT, RIGHT, TO MOVE THE   WHEELCHAIR

WORKING PRINCIPLE EARLIER VERSION

THE MOUTH DEVICE CONTAINS MAGNETIC FIELD SENSORS MOUNTED ON ITS FOUR CORNERS TO DETECT THE MOMENT OF THE TINY MAGNET ATTACHED TO THE TONGUE.

DESiGN OF TONGUE DRIVENEW VERSION

MOUTH DEVICE

sens

or

Orthodontic

brace

DESIGN OF TONGUE DRIVE

IT IS POWERED BY A LITHIUM-ION BATTERY AND HAS AN INDUCTION COIL TO RECHARGE IT AND IS PROTECTED WITH A WATER-RESISTANT MATERIAL.

NEW VERSION

MOVEMENT OF THE MAGNETIC TRACER ATTACHED TO THE TONGUE IS DETECTECD BY SENSORS.

\ THE OUTPUT SIGNALS FROM THE SENSORS ARE WIRELESSLY TRANSMITTED TO AN IPOD TOUCH OR  IPHONE . SOFTWARE INSTALLED ON THE APPLE DEVICE WORKS OUT THE RELATIVE POSITION OF THE MAGNET WITH RESPECT TO THE ARRAY OF SENSORS IN REAL TIME AND INTERPRETS THE

USER'S COMMANDS.

WORKING PRINCIPLENEW VERSION

WIRELESS SIGNALS FROM THE DEVICE COMMUNICATE WITH A WHEELCHAIR-DOCKED IPHONE OR IPOD WITH SOFTWARE INSTALLED THAT INTERPRETS TONGUE COMMANDS. THE MOVEMENTS CONVEYED ARE THEN USED TO CONTROL THE POWER WHEELCHAIR. 

WORKING PRINCIPLE

THIS INFORMATION IS THEN USED TO CONTROL THE MOVEMENTS OF A CURSOR ON THE COMPUTER SCREEN OR TO SUBSTITUTE FOR THE JOYSTICK FUNCTION IN A POWERED WHEELCHAIR.

WORKING PRINCIPLE

ADVANTAGE

A RESPONSE TIME OF LESS THAN ONE SECOND

WE CAN CONTROL ENVIROMENTAL DEVICE

EMPLOY ABILITY

DISADVANTAGE

SLIGHTLY COSTLIER.

IMPLEMENTATION I S SLIGHTLY HARDER

Future of TCS :-

TO CONTROL A ROBOTIC ARM TO USE IT TO EAT, DRINK, HOLD ANY THING AND USE IT AS A NATURAL ARM.

TO DRIVE CARS
