Basic Concept
Exchange messages between a driver of the front vehicle and the back vehicle by using OWC technology
A driver’s speech is delivered based on OWC to target drivers
Target driver can read or hear the message
Transmitter(TX) and receiver(RX)
The front vehicle
RX : rear camera / side camera
TX : rear light / blinker / window signage
The back car
RX : front camera
TX : front light / blinker / window signage

4. Traditional ways for communication between drivers

Traditional ways for communication between drivers
Traditional ways to communicate between drivers
Horn honking/flashing lights : warn danger or express complaint to other drivers
Sign language : inform status of vehicle or warn danger
Emergency light : inform abnormal status, show appreciation or apology
Disadvantages of traditional ways
Unclear
Makes other drivers uncomfortable
Unnecessary broadcast
Sign language is not familiar to some drivers
Drivers may lose attention on driving for a while

Use cases for OWC based Messaging Application
Communication between drivers
Drivers can ask clearly what they want to the target driver
Can prevent annoying honking sound or flashing light
Drivers can maintain attention on driving while communicating with other drivers
Drivers can have small talk
Give detail information about abnormal status of an adjacent vehicle
Instead of honking horn or flashing light, specifically describe status of the vehicle
E.g. flat tire, which tire is punctured, smoke from the car etc.
Notify my situation to other drivers
Instead of turning on emergency light, specifically explain status of my problem
E.g. health problem, emergency situation, detail information about car trouble

Conclusion
Traditional communication ways between drivers are unclear, noisy and danger
By using OWC driver can communicate directly
Driver-to-driver messaging application using OWC can deliver clear message without noise and losing attention on driving
