AirBoard

Point your phone at a wall and your finger becomes the marker. AirBoard uses gesture detection and computer vision to track where you're "writing" and turns any surface into a smartboard — no projector, no hardware beyond the phone.

Built for teachers: it layers in an LLM so the board can help explain and expand on what's being taught, making for a more immersive classroom on top of any blank wall. Won the Healthcare & Education track at DevSOC 2025, CodeChef VIT's flagship hackathon.
