QUADRIPLEGIA

ITS ALL ABOUT….

Quadriplegia = quadric + plegia

CAUSECAUSE

Spinal cord injury avoids the sensory

and motor signals to communicate with the

limbs leading to paralysis .

EFFECT

Only head movement is possible

OBJECTIVE

Our Goal……

Interface between the paralyzed

patients and the external world patients and the external world

and thereby helping them to

improve their quality of life.

RESOURCES

HARDWARE

� ACCELEROMETER (TO SENSE THE HEAD MOVEMENT)

� 8051 MICROCONTROLLER (MASTER CONTROL)

� ADC (SIGNAL INTERCONVERTION)

� GSM (COMMUNICATION) � GSM (COMMUNICATION)

� MAX 232( LOGIC CONVERSION)

SOFTWARE

� VISUAL BASIC V6 (BACKEND DESIGN)

� KIEL U VISION (CODING)
