2. ABSTRACT
 This project discuss on the current use of gestures in domestic
appliances and possible usage for various other domains.
 The overview of products is given with varying input methods.
 A perfect example is the radio control by hand gesture. This
idea made it possible to change the channel, and change the
volume with the use of hand gestures.

3. PROPOSED SYSTEM
 Free hand motion (free space).
 Using electric field (E-field).
 Easy deployable to most applications.

8. ARM 7 PROCESSOR
 32-bit ARM7TDMI-S microcontroller in a tiny LQFP64 or
HVQFN package.
 32 KB of on-chip static RAM and 512 KB of on-chip flash
program memory.
 128-bit wide interface/accelerator enables high-speed 60 MHz
operation.
 In-System programming/In-Application Programming
(ISP/IAP) via on-chip boot loader software.

9. WORKING MODEL

10. RADIO FREQUENCY (RF)
 Radio frequency (RF) is any of the electromagnetic wave
frequencies that lie in the range extending from around 3 kHz to
300 GHz.
 It include those frequencies used for communications or radar
signals.
