Overview

Tangible control in spatial computing.

Interacting with complex 3D medical datasets like MRI and CT scans in virtual space can be cumbersome using standard controllers. The challenge was to bridge the tactile precision of a physical control panel with the infinite bounds of spatial computing.

This project introduces an Arduino Uno and ESP32-based physical control panel that wirelessly communicates with a Meta Quest 3 headset. Sensors, dials, and physical inputs translate directly into the manipulation of volumetric medical imagery.

Through bidirectional real-time serial communication, users can collaboratively inspect, slice, and interact with the 3D data across networked headsets via Photon Fusion 2, enabling unprecedented remote surgical planning and educational simulations.

Process

Hardware to software bridge.

01
Hardware prototyping

Designing and assembling the physical control panel using Arduino Uno and ESP32 microcontrollers.

02
Serial communication

Establishing a low-latency bidirectional data flow between physical sensors and the Unity simulation via a wireless ESP32 bridge.

03
Volume rendering

Implementing rendering techniques to display complex medical MRI/CT scan data as interactive 3D volumes in Unity.

04
Multiplayer sync

Integrating Photon Fusion 2 to ensure all physical inputs and volumetric manipulations are instantly synchronized across multiple users.

Capabilities

Under the hood.

Custom embedded hardware

A bespoke control panel utilizing Arduino Uno and ESP32 handling multiple sensor inputs, providing a tactile interface that standard VR controllers cannot mimic.

Volumetric rendering

Medical MRI and CT scan data points are translated into fully rotatable, sliceable 3D volumes enabling real-time spatial inspection from any angle.

Bidirectional serial comms

An optimized data stream where physical panel states affect the virtual environment, while virtual simulation states can trigger physical feedback mechanisms.

Networked collaboration

Photon Fusion 2 architecture that seamlessly synchronizes the dense volumetric data states and hardware inputs across a shared multiplayer XR session.
