Tongue motion based wheel chair motion for physically handy
caped and patients
Aim:
This project main aim is operating wheel chair with tongue motion using for handy caped
and patients.
Abstract:
Tongue Drive system (TDS) is a tongue-operated unobtrusive assistive technology,
which can potentially provide people with severe disabilities with effective computer access and
environment control. It translates users’ intentions into control commands by detecting and
classifying their voluntary tongue motion utilizing a small permanent magnet, secured on the
tongue, and an array of magnetic sensors mounted on a headset outside the mouth or an
orthodontic brace inside.
The magnetic sensors are nothing but hall-effect sensors. A Hall Effect sensor is a
transducer that varies its output voltage in response to changes in magnetic field. In its simplest
form, the sensor operates as an analogue transducer, directly returning a voltage. With a known
magnetic field, its distance from the Hall plate can be determined. The control system consists of
Hall Effect sensor and microcontroller. Microcontroller collects data from the sensor and
Microcontroller makes to move the motors of the wheel chair in appropriate direction. The
direction is decided by the microcontroller depending on the magnet present at different Hall
Effect sensors. The microcontroller is loaded with intelligent program written using embedded
‘C’ language.

Application and advantages

The signals from the magnetic sensors are linear functions the magnetic field, Thus a few
sensors are able to capture a wide variety of tongue movements. This would provide a
tremendous advantage over switch based devices in that the user has the options of
proportional, fuzzy, or adaptive control over the environment.

These would offer smoother, faster, and more natural controls as the user is saved the
trouble of multiple on/off switch operations. In Tongue Drive system on the other hand,
the additional switches are unnecessary since a specific tongue movement can be
assigned to the button press

he permanent magnet which generates the magnetic field is a small, passive, and
inherently wireless component leading to user convenience and additional power saving.
Due to the proximity of the magnet and Hall-effect sensors in the oral cavity, the Tongue
Drive system is expected to be more robust against noise, interference, and involuntary
movements compared to alternative technologies

hospital and home application
Software / IDE Using:

IDE AVR-v4 Compiler for Embedded C Programming.

Prog ISP-7 programmer for dumping code into Microcontroller.

Proteus-7 for Hardware simulation / circuit designing
1. What microcontroller using? And why?
Ans: We are using AURDINO , (ATMEGA family, AVR)

Because “Arduino is an open-source

Electronics prototyping platform based on flexible, easy-to-use hardware and software.

It’s intended for artists, designers, hobbyists, and anyone interested in creating
interactive objects or environments.

“Arduino can sense the environment by receiving input from a variety of sensors and can
affect its surroundings by controlling lights, motors, and other actuators.

 Can you write a program without main() in any compiler?
 What is Difference between voltage and current?
Note: “Potential difference between two points & speed of electrons between two points “are
definitions not difference!!!
 To Step down AC power we can use “Step down transformer”
Then what is Step down DC Power Module?
 Can you step down DC Power without using Transformers or Voltage regulator?
 What is a device name, which activates with only positive current terminal (-ve no need)?
