2. 01/25/122 Project Overview

3. Overview LED Matrix display for back window of car Will interface with Android phone via Bluetooth, using voice recognition and a user interface for easy update of the display Distance sensor to automatically display user-defined message when following driver gets too close Rechargeable by car outlet

4. 01/25/124 Current Work Researching Buying parts Finalizing ideas

5. 01/25/125 Technical Considerations Bluetooth receiver will receive signal from phone Microprocessor will interpret and send message to LED driver LED driver will output the message to the display Distance sensor will communicate with microprocessor through XBEE transceivers Microprocessor will interpret information and cause the LED driver to send user-defined message to LED display when someone drives too closely behind the customer's vehicle

6. Writing effective Android application with user-friendly interface Making use of phone's voice recognition Configuring Bluetooth communication between phone and microprocessor Making distance sensor work effectively with displaying message at the proper time – i.e. not display rude canned message if someone pulls up close while stopped at a traffic light – Possible solution: Use phone GPS to have message only display while the car is moving Technical Challenges
