Useful Reality - Assistive wearable tech on a budget
summary
Claims a usable assistive wearable AR stack for about $500 instead of $5,000, built from off‑the‑shelf parts: a single‑board computer (banana pi zero or Raspberry Pi Zero 2), a budget vufine style head‑mounted display (~US$200), a gravity mouse with mini keyboard, finger‑mounted or endoscope cameras (about 4 fps), phone‑style batteries and a USB power‑board, cheap magnetic I²C connectors and BLE sensor pucks. A foam armband prototype runs GStreamer and a framebuffer PDF viewer and works for documentation, magnification and sensor readouts, though shoulder or head mounting now seems preferable.
