Background
Real-Time In-Helmet Navigation and Mobile Integration for Safer, Smarter Riding
The HUD for Bike Helmet project was developed to enhance rider safety and convenience by providing real-time information directly within the rider's field of view. Traditional navigation and phone interaction methods require riders to look away from the road, increasing risk. This project aimed to integrate a compact heads-up display system into a helmet, enabling seamless access to navigation, notifications, and mobile data while maintaining full focus on the ride.

Solutions
How We Built It
Our Approach
Raspberry Pi-Powered HUD with Android Auto & Dual Wireless Connectivity
A heads-up display system was developed using the Raspberry Pi 4 running Linux as the core processing unit. The system was integrated with the Android Auto SDK to enable seamless display of mobile content on a compact screen within the helmet. BLE and WiFi connectivity were implemented to connect with mobile devices and transmit data in real time. The system architecture focused on smooth integration, responsive performance, and reliable communication, ensuring a practical and effective in-helmet display experience for riders.

Client Feedback
What the Client Said
"
Glancing down at my phone for directions used to be something I did without thinking — until it nearly cost me. This HUD changed everything. Navigation is right there in my view, turn-by-turn, without breaking my focus for a second. The Android Auto integration feels completely natural, not like a workaround. It's the kind of product that makes you wonder how you rode without it.
