Project "Shi": Affordable Open Source Augmented Reality Glasses
summary
AR hardware aims to reach Star Wars–level overlays but current headsets start around $3,500; this project targets a different route: three prototypes in four weeks, offloading heavy compute to the phone to cut size and power, and a radically simple optics approach using a transparent OLED a few millimeters from the eye plus a small lens. Goal is price below a smartphone and the prototype uses an ESP-based board (~$3) that runs face detection and streams video.
