Air travel can be a challenging experience for illiterate or low-literacy passengers, particularly when faced with unfamiliar languages, written instructions, or digital interfaces. These barriers often lead to confusion, miscommunication, and a dependence on others for even basic needs. To address this issue, this project proposes an AI-powered communication assistant that uses Image recognition and RF wireless technology to help such passengers interact easily with cabin crew and navigate onboard services without reading or writing. The core components of the system include a wearable or seat-integrated device equipped with a  RF module, along with a multilingual AI engine for image processing. Cabin crew receive translated alerts on a tablet or mobile device, complete with passenger identity and location data. This solution ensures real-time, accessible communication for illiterate passengers, enhancing safety, comfort, and inclusivity during air travel. Additionally, by integrating RF tracking and predefined commands, the system minimizes crew workload and streamlines passenger support, especially during emergencies or service requests. In this project we use Touch screen Technology to make it easy even to illiterates as it is also included with images behind touch screen module, 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 RF technology. This project consists of RF based system that transmits the wireless signals according to the input given by the user, using touch screen. At the receiver (airhostess) end the information will be displayed on LCD in English language. Here when the user sends his need through a gentle touch on touch screen, then micro controller transmits that information through RF transmitter. The information received by the RF  receiver will be displayed on LCD.    

The main objectives of the project are:  

• To assist illiterate or low-literacy passengers in air travel.
• To enable communication through a touch-based interface with images.
• To reduce language barriers between passengers and cabin crew.
• To use RF technology for wireless transmission of passenger requests.
• To display translated passenger requests on an LCD at the crew's end.
• To enhance safety, comfort, and inclusivity during flights.
• To minimize crew workload and streamline passenger support.
