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
AIM OF THE PROJECT

• 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
• Controlling a robot
• Controlling the home appliances
• Voice enabled communicator
• To design the above mentioned futuristic device,
  we are opting for MEMS(Micro Electro Mechanical
  Sensor) Technology.

RF Transmitter circuit

• 433.92 MHz Frequency
• Low Cost
• 1.5-12V operation
• 11mA current consumption at 3V
• Small size
• 4 dBm output power at 3V

10
RF Receiver circuit

• Low Cost
• 5V operation
• 3.5mA current drain
• No External Parts are required
• Receiver Frequency 433.92 MHZ
• Typical sensitivity -105dBm
• IF Frequency 1MHz

11
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.

12
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 ones slave robots just
  by hand gestures by this technology.

19
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.

20
FUTURE SCOPE

• Adding Zigbee Module
• Adding GPRS and GPS
• Adding Video Camera for live streaming
• Connecting Bomb detector or metal detector
• Adding Temperature Sensor
