I am missing my left eye, I struggle with distance measurements and I struggle with giving a clear indication to others that I cannot see and that they may need to be careful on my left.
I engineered a 3D printable eye-patch that is to be printed by biocompatible resins and the patch can hold Time Of Flight cameras that sense the distance on specific angles (eye periphery) and also hold esp32s.
I developed a minimalist android application that connects to such esp32s and read the characteristics and vibrate when the distance is too close so that I can receive vibration on my phone before hitting walls/doors/obstacles as I walk through the streets/office. The eye also gives a clear message that I cannot see.
After the initial submission feedback I decided to include a 3D printed "glove" of sorts that allows to have such ToF cameras pointed at different directions (where the hands point to).
The esp32s talk to each other and send the measurements. There are different policies on how to process such measurement signals based on urgency and available devices (i.e. a device may be out of battery).
