Touch Screen and Zigbee Based Wireless Communication Assistant
In this paper, the authors construct a user friendly multi-language communication system for illiterate/dumb people traveling by Airlines. As they have different languages in their world and its impossible for them to know all the languages. So, in this paper, they are building a device that helps them in expressing their needs with other language people (Airhostess) i.e. request them if they need anything in the flight like coffee, tea, drinks etc. In this paper, they use GLCD and touch screen technology to make it easy even to illiterates as it is also included with images, which indicates the needs.
