Inspiration
Distracted driving causes so many preventable accidents every year. I wanted to create something that reacts in real time to help drivers stay focused. That idea became DriveGuard, powered by Free-WiLi, a system that monitors where the driver is looking and uses LED feedback to keep them alert.
What it does
DriveGuard uses computer vision to track the driver’s eyes and head position.
If the driver is distracted, the Free-WiLi LEDs turn red to warn them.
If the driver is focused, the LEDs stay green.
Everything happens live, giving the driver constant awareness of their focus on the road.
How we built it
The system was built using Python, OpenCV, and MediaPipe for tracking, along with Free-WiLi scripts to control the LED indicators. A simulated driving video runs beside the webcam feed to mimic a real driving environment and test the system’s accuracy.
Challenges we ran into
It was challenging to work with a system I had no prior experience in. The Free-WiLi scripts were difficult to find and understand at first, so I had to do a lot of research and testing to get everything working properly. Integrating new hardware with computer vision took time and patience.
Accomplishments that we're proud of
- Fully functional system
- Successful integration with Free-WiLi
- LED light feedback that clearly shows driver status
- Real-time system that runs smoothly
What we learned
I learned how hard it can be to bring multiple systems together, but also how rewarding it feels when it works. I also discovered how powerful computer vision is — especially MediaPipe. It was amazing to see it detect distraction even when my head was straight but my eyes were wandering.
What's next for DriveGuard
Next, I want to integrate the Free-WiLi bracelets for more feedback and possibly add a beep sound when distraction is detected. I also plan to optimize the system to reduce delay and make it react even faster.
