LiDAR Glasses

Visually impaired individuals have limited options for blending in when out in public

Visual-assistance options are limited to a cane and seeing eye dog, that's it. There has to be a better way.

1. Sense

   Two wide depth sensors on the frame scan ahead, 120° across and up to 5 m out. A third, angled 40° down, watches the ground for curbs and drop-offs. A motion sensor tracks head tilt, so looking down at the floor doesn't read as an obstacle.

2. Decide

   A Raspberry Pi 4 in a pocket merges all three sensors into one depth map. Each point is scrutinized against the surrounding points to ensure no false positives light up a motor.

3. Feel

   16 vibration motors on the chest/torso. Columns show direction and rows show height:

   1. Uneven ground
   2. Trip level
   3. Torso height
   4. Overhead

   The closer something is, the harder it pulses.

• CABLES EVERYWHERE
• Heavy sunlight corrupts data
• Motor fidelity

If you're blind or have low vision, or work with people who are, your input on what would actually help matters more than anything else this project can get.
