Conclusion
1.ABSTRACT:
The Main aim of this project is to construct a user friendly multi
Language communication system for illiterate/dumb people traveling by
Airlines. As We have different languages in our world 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
(Airhostess) i.e. request them if we need anything in the flight like coffee,
tea, drinks etc. In This project we use LCD And 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 airhostess in
receiving the customers with different languages. Here For wireless
communication purpose we use XBee technology.
2.OBJECTIVES:
This system
“Touch screen and XBee based wireless
communication assistant for dumb /illiterates in airlines” was designed a
user friendly multi-language communication system for illiterate/dumb
people.

4. METHODOLOGY:
The transmitter will have the Touch plates sensors , when touch the
particular touch plates that is detected then it gives the signal to the ARM, then
the ARM will send the information to another receiving station through XBee. At
the same time ARM will generate the out put that is fed to buffer IC 4050 ,buffer
stores and given to the driver IC 2003 in driver current will amplifies and
voltage will inverts with the help of Darlington circuit of driver IC to drive the
relay . Then signal is given to the output load for indication purpose.
When ARM receives the data from the XBee, it will enable the alert through
announce which is stored information voice chip for particular touch plates.
5. ADVANTAGES & DISADVANTAGES:
 ADVANTAGES:
1.
Very useful even for illiterates.
2.
Voice based user input.
3.
Faster and secure data transmission.
4.
User friendly and easy to install.
5.
Helpful in abroad to express user need.
DISADVANTAGES:
In this project usage of relays leads to consume more power.
6.APPLICATIONS:
1. Smart Energy
2. Health Care
3. Home Automation
4. Security services
5. Communication and device discovery

7.CONCLUSION:
Integrating features of all the hardware components used have
been developed in it. Presence of every module has been reasoned out and
placed carefully, thus contributing to the best working of the unit. Secondly,
using highly advanced IC’s With the help of growing technology, the
project has been successfully implemented. Thus the project has been
successfully designed and tested.
