i want documentation and ppt of touchscreen based assistance for dump and illetrate using zigbee.

The main objective of this project is to build a user-friendly multi-language communication system for the illiterate / dumb who travel by the airlines. As we have different languages in our world and it is impossible for us to know all languages. Therefore, in this project we are building a device that helps express your needs with other people of the language (Air Hostess), that is, if you need something on the flight like coffee, tea, drinks, etc. In this project Uses GLCD and touch screen technology to make it easy for even the illiterate because it is also included with the images, indicating the needs. This even reduces the difficulty to the hostess in receiving customers with different languages. Here for the purpose of wireless communication uses Zigbee technology.
ZigBee is a wireless technology developed as an open global standard to meet the unique needs of low-cost, low-power wireless sensor networks. Zigbee is the set of specifications built into the IEEE 802.15.4 wireless protocol.
As Zigbee is the next technology in the wireless field, it has a treaty to demonstrate its form of functionality and procedures, advantages and disadvantages using a small control application of any kind of electronic devices and machines. Zigbee technology is widely adopted for bulk and fast data transmission through a dedicated channel. This project is based on a system based on the technology that transmits the wireless signals according to the input given by the user through the touch screen. At the end of the receiver, the information is displayed in GLCD in English. Here, when the user sends their need through the touch screen, the micro controller transmits that information through the Zigbee transmitter. The information received by the Zigbee receiver is shown in GLCD.
