2. TOUNGE COMPUTING SYSTEM

3. INTRODUCTION :-
This technology is new inductive tongue-computer interface to be used for the disabled people for environmental control.
This technology is also called as “TONGUE DRIVE SYSTEM”

4. PARTS OF TONGUE COMPUTING :-
Permanent
magnet
Magnetic
sensors
Control unit
External
receiver

5. IMPLANTATION :- Permanent magnet  placed on the tongue
Magnetic sensors  wore as a head set
Wireless t transceiver  connected to the headset and wore to head

6. Operation of Tongue computing ( TDS) :-

7. Internal working :-

8. Signal processing :-

9. Applications :- A disabled person can drive a wheel chair.
Can operate a computer in which the person can type words, play games.
Manipulation of a mobile device through an assistive tongue computing.

10. 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 use in everyday purpose and to control the activities going on around without any difficulties.

11. Conclusion:-
The operating principle and set up of such a novel passive tongue HCI has been established with successful laboratory trials & experiments
Further clinical trials will be required to test out the devices on disabled persons before it is ready for future commercial development

12. Result :-
The device is able to perform two main pc functions that of the keyboard and mouse.
The results show that this device allows the severely disabled person to have some control in his environment such as to turn on/off or control daily electrical appliances.
Also can be used as a viable pc human computer interface (HCI)by tongue control.
