This document summarizes a project that uses touchless hand gesture motion technology to control home appliances. A gesture recognition chip detects hand motions and sends signals to a microcontroller. The microcontroller then operates relays connected to devices like lights and fans. This allows disabled people to control devices without physical contact. The system provides a low-cost and accurate alternative to existing gesture and voice control methods. It has applications for assisting elderly, sick, and handicapped individuals in smart homes.

2. OBJECTIVE
•To control the home appliances with ease from their place
itself by using touchless hand gesture technology.
•It mainly focus the disabled persons to control the
electronic devices without moving.
•For Ex: Electronic device such as light,fan and its
speed,TV,etc...can be easily controlled.

3. ABSTRACT
•To creating the ideal smart homes environment.
• Special attention for elderly person, sick patients, and
handicapped person.
• Touchless hand gesture motion is used as command for
controlling the devices.
• Recognizes movement of the hand motion from one
direction to another with help of Gest IC MGC3130.

4. CONT…
• MGC3130-3D gesture recognition and tracking
controller chip.
• It has one transmit and five very sensitive receive
channels of electrodes.
• It is capable to detect distortions of a transmitted
electrical field corresponding to capacitive changes.
• Spatial arrangement of the electrodes allows the chip to
determine the center of gravity of the electric field
distortion. Finally it triggers the relay for the output.

5. INTRODUCTION
• In a modern era to turn ON and OFF the electronic
appliances is very tough task.
• To turn ON and OFF of any devices with the help of gest
IC MGC3130.
• It provides a transmit signal to generate the E-field, in
form of analog signals from the receiving electrodes and
processes this data to digitally.
• It works by the movement of hands motion from one
direction to another direction.

11. GESTURE BOARD
•(3D) gesture recognition and
tracking controller chip
technology.
•Enables user command as input
with natural hand and finger
movements.
•Low-power consumption 3.3v.
•One transmit and five very
sensitive receive channels.

12. ELECTRODES OF GESTURE BOARD
• They consist of one Tx and five Rx electrodes.
• North, East, South, West, Center which are placed in
different layers and center electrode is crosshatched.
• The dimension of the board is 120 x 85 mm and
sensitive area is 95 x 60 mm.

13. OPERATION OF THE BOARD
• 3D sensor technology utilizes an electric field for
advanced proximity sensing.
• E-fields are generated by electrical charges and
propagate 3D around the surface.
• Transmit frequencies range-100 kHz which reflects a
wavelength of about 3km.
• Four receiver electrodes to detect the E-field variations
at different positions.

14. DISTORTED E-FIELD
• To measure the origin of the electric field distortion
from the varying signals received.
• From this it is used to calculate the position, track
movements and to classify movement patterns.

15. PIC MICROCONTROLLER
(PIC16F877A)
• Fully static design.
• Wide operating voltage range (2.0V to 5.5V).
• 100,000 erase/write cycle Enhanced Flash.
• Serial Programming.
• Easily Programmable.
• Low cost.
• Power saving mode.
• Selectable oscillator options.
• Low-power, high-speed Flash/EEPROM technology.
