  3. 3. Currently around 10 per cent of the total world's population ,i.e. , Around 650 million live with a disability. Dependency on others 85% of people with disability are found in developing countries. About 4% of indian population are affected.
  4. 4. EXISTING TECHNOLOGY  The present technologies make use of geared motors to move in various directions.  These systems are steered using joysticks and by hand some times.  These systems are equipped with normal braking systems.
  5. 5. PROPOSED TECHNOLOGY MEMS Micro-Electro Mechanical Systems
  6. 6. Micro-Electro Mechanical Systems  MEMS is a gesture based technology  It is an integration of mechanical and electronic circuits, typically on a semiconductor chip through micro fabrication technology.  “lab on chip” technology.  Ranges : 1 - 100 microns

  8. 8. COMPONETS OF THE BLOCK DIAGRAM POWER SUPPLY  MICRO CONTROLLER  MEMS ACCELEROMETER  MOTOR DRIVER CIRCUIT  VOICE IC  LCD  MOTORS  SPEAKERS
  9. 9. Regulated Power Supply     12 v battery. Bridge rectifier Capacitive filter Voltage regulator
  10. 10. Micro-controller
  11. 11. Features of AT89S52  8K Bytes of Re-programmable Flash Memory.  RAM is 256 bytes.  4.0V to 5.5V Operating Range.  Fully Static Operation: 0 Hz to 33 MHz’.  256 x 8-bit Internal RAM.  32 Programmable I/O Lines.  Three 16-bit Timer/Counters.  Full Duplex UART Serial Channel.  Fast programming time.  8 Interrupt sources.
  12. 12. MEMS ACCELEROMETER 1st generation 3axis sensor. MM7660L Used in moving, slope detection. User could get acceleration value of x, y, and z axis. Output sensitivity could be select by simply set voltage level on few pins.

  18. 18. VOICE IC         APR 9600 RE-Recording Voice IC Non-volatile Flash memory technology No battery backup required User-Selectable messaging options Low power consumption Operating current: 25 mA typical Standby current: 1 uA typical Automatic power-down
  19. 19. SPEAKERS To give the voice output. Alerting system used
  20. 20. Process Diagram • ORIENTATIO NS ARE RECORDED BY THE MM7360L • (sensor) PMMA 7660 MICRO CONTROLLE R • Accept the values sends to actuator • Controls the robotic movement MOTOR DRIVER CIRCUIT •Command is displayed MOVEMENT ‘N” CONTROL • Robot moves in specified direction.
  21. 21. KEIL SOFTWARE      µvision3 It is used where machine language code is written and compiled. Then source code is converted into hex code. This is to be dumped into the micro controller for processing. Keil compiler also supports c language code.
  22. 22. ADVANTAGES  REDUCES PHYSICAL STRAIN  REDUCES HUMAN ACTIVITY
  23. 23. APPLICATIONS  Used for people who don’t have much stamina to move.
  24. 24. APPLICATIONS  For disable persons  Cultural sports and
  25. 25. CONCLUSION  The project “GESTURE BASED VEHICLE MOVEMENTS CONTROL AND ALERTING SYSTEM” has been designed and implemented with Atmel 89S52 MCU in embedded system domain.  The direction of X-axis, Y-axis, and Z-axis has been found by acceleration sensor and according to that the wheel chair is moved with the help of dc motor in the desired direction.
  26. 26. FUTURE SCOPE Virtual helper for blind people. Remote applications.
