Navigation Assistant for Visually Impaired
This prototype consists of an Android application and a wearable, which communicate through BLE. It demonstrates the basic functionality of NAVI.
The Android application counts your steps and sends a random signal (vibrate once or vibrate two times) for every ten steps. After 40 steps a finish signal is sent, which triggers the wearable to vibrate for five seconds.
The wearable consists of a ESP32, which controls a vibration emitter.
This project was build as part of the lecture Mobile Innovations for Global Challenges by Dr. Christelle Scharff. Check the wiki for more information.
