The
main aim of this project is to construct a user friendly multi-language
communication system for illiterate/dumb people travelling around the
country. As we have different languages in our country and its
impossible for us to know all the languages. So, in this project we are
building a device that helps them in expressing their needs with other
language people i.e. request them if we need anything in the
restaurants like coffee, tea, drinks etc. In
this project we use Touch screen Technology to make it easy even to
illiterates as it is also included with images, which indicates the
needs. This even reduces the difficulty to restaurant people in
receiving the customers with different languages. Here for wireless
communication purpose we use Zigbee technology.
ZigBee is a wireless technology developed as an open global standard to address the unique needs of low-cost, low-power, wireless sensor networks. Zigbee is the set of specs built around the IEEE 802.15.4 wireless protocol.

As
Zigbee is the upcoming technology in wireless field, we had tried to
demonstrate its way of functionality and various aspects like kinds,
advantages and disadvantages using a small application of controlling
the any kind of electronic devices and machines. The Zigbee technology
is broadly adopted for bulk and fast data transmission over a dedicated
channel.
This
project consists of Zigbee based system that transmits the wireless
signals according to the input given by the user using touch screen. At
the receiver end the information will be displayed on LCD in English
language. Here when user sends his need through touch screen, then micro
controller transmits that information through Zigbee transmitter. The
information received by the Zigbee receiver will be displayed on LCD.
