Selected work

Eight of 19 shipped projects. 9 have a full case study behind them.

• Markerless Motion Capture2025–26

  Four RGB cameras, one Jetson Orin NX, a 17-joint skeleton streaming live into Unity and Unreal — no suits, no markers, no workstation.

  Real-time multi-user capture at 87% accuracy

  13× speedup45 fps87% accuracy

• VR Helicopter Simulator2022

  Physics-based flight with six degrees of freedom on a motion platform, modelling two helicopters in service with the Indian Air Force.

  Demonstrated to the Prime Minister of India

• Tidal Tactics2023–25

  Mixed-reality ship battle on Quest, paid on the Meta store. Your own room becomes the sea — bomb your floor to find the hidden fleet, solo against an AI that learns or head-to-head in the same room.

• MR Weapons Trainer2023

  Machine gun training in mixed reality at PC fidelity — a real weapon on a serial link, ballistics modelled from the round up, scored and debriefed.

  In active use for foreign military weapons training

• Jagannath Puri — Divine Offering2025

  A pilgrimage staged at the Rath Yatra in Puri — mix an offering in mixed reality with your own hands, then watch the stall dissolve into the temple to leave it there.

• Trapmaker2026

  An asymmetric build-and-raid platformer that lives inside Reddit. Every level is a real post, playable in the feed — and every stranger who dies in your trap pays you.

• Vision Therapy in VR2023–24

  Games that diagnose and treat eye conditions. A headset can show each eye a different image and watch where both of them go — which turns a clinical assessment into something you play.

  Main developerUnity · Pico Neo 3 · Tobii eye tracking · C#

• Molecular Mayhem2026

  A Snap Lens where you strap one of four absurd chemical fuels to a vintage kart, set angle and power on oscillating dials, and launch a friend’s Bitmoji across the desert for distance.
