Mixed Reality for Social Good
summary
Community project that brings VR into hospitals (VR Passport) and trains volunteers — about two thirds nontechnical — using a concrete stack: Android Things on a Raspberry Pi (recommend MX7), Lego + 3D-printed connectors, motors driven via an L293D motor driver, realtime sync through Firebase DB, AR scenes built with AR.js (32 mm marker scale reported), and VR built in Unity for Daydream VR. Delivered a working mixed‑reality prototype: blinking LED and conveyor belt controlled from the cloud, AR alignment limits noted but overall system runs and has been used in workshops and hospital visits.
