AI Glasses That Tell the Blind What’s Ahead
A camera and a LiDAR on a pair of glasses measure what is in front, and the phone says it out loud, like “Something ahead: about 3 m.”

Kids OK, with an adult
DIY project. Children must build this only with an adult (16+ years) beside them at all times. Not suitable for children under 8 years.
A learning project, not a mobility aid: a blind user should keep using a cane or a guide. You need your own AI service key; keep it private and never share the code with your key in it.
Strictly follow the description given with this video.
Video
How it works
- The LiDAR measures the distance to whatever is straight ahead, many times a second.
- When something comes close, the ESP32 camera board takes a photo.
- Over the phone’s hotspot, the photo goes to an AI service that describes the scene in a few words.
- The phone page speaks the distance and the description aloud.
