CHALLENGE
To create a multi-tasking device that should be user friendly even for physically handicapped people.
To create a device that should be helpful for the people who are dumb, in their daily life.
To create a robotic device which can be controlled by using gestures unlike a traditional remote controlled device.
To increase the level of comfort.

PROPOSED SYSTEM
To create a single “Glove” which is useful for multiple applications using the hand gestures (wireless).
The different applications that we are going to implement here are:
I.Controlling a robotII.Controlling the home appliancesIII.Voice enabled communicator
To design the above mentioned futuristic device, we are opting for “MEMS”(Micro Electro Mechanical Sensor) Technology.

MEMS Micro-Electro-Mechanical accelerometer Sensor (MEMS) is the integration of
mechanical elements, sensors, actuators, and electronics on a common silicon substrate through micro fabrication technology.
An accelerometer measures acceleration (change in speed) of anything that it's mounted on.
Three-axis accelerometers measure acceleration in three directions. The MEMS we use in our project is MMA7260Q.
11
Applications of MEMS
MEMS-based sensors are a crucial component in automotive electronics, medical equipment, smart portable electronics such as cell phones.
PDAs, and hard disk drives, computer peripherals, and wireless devices.
These sensors began in the automotive industry especially for crash detection in airbag systems.

ADVANTAGES
Easy to operate
Low power consumption
User friendly
Single equipment = multiple applications
When extended further in the hardware section ,numerous applications can be added
One can able to control one’s slave robots just by hand gestures by this technology.
18
APPLICATIONS
Plays a major role in helping deaf and dumb people in their daily life.
Can be used as an assistance for physically challenged people.
Military applications
Geographic excavations
General purpose device for better living
Useful for Animal Planet, Discovery people for their studies on animals by playing different sounds & for their exploration.
