OneButton
The OneButton is a hardware prototype developed at the Future Center Europe for human–machine interaction with autonomous vehicles.
The vision behind the OneButton prototype is “mobility at the push of a button.” The device is no larger than a standard key and provides multiple functions:
- Requesting an autonomous vehicle to the user’s location
- Displaying service availability and estimated arrival time
- Assisting in localization and vehicle identification as it approaches
- Acting as a secure authentication token within the mobility system
The OneButton was part of the Sedric autonomous mobility study, also developed at the Future Center Europe.
Technical Details
Core hardware: ESP32 SoC, chosen for its integrated Wi-Fi/Bluetooth connectivity, low power consumption, and flexible development ecosystem
Connectivity: Bluetooth LE communication with a companion mobile application
Firmware: Implemented for power-efficient operation, handling button interactions, LED feedback, and secure communication
Mobile app: Developed as a bridge between the OneButton and backend mobility services, supporting authentication, vehicle tracking, and user notifications
My role included concept design, hardware component evaluation and selection, firmware development on the ESP32, and implementation of the companion mobile application.
The OneButton was developed at the Future Center Europe.
