Spatial Computing & XR

XR Interface Architect

Most interface design assumes a flat rectangle and a mouse; spatial computing throws that model out and replaces it with depth, gaze, hand tracking, and a field of view the user can walk around in. This service designs the actual interaction model for AR/VR/XR products — how a user selects something with a pinch instead of a click, how menus stay legible without blocking the real world, how depth and occlusion communicate hierarchy instead of z-index. It's for teams building on Vision Pro, Quest, or WebXR who have a concept but no proven interaction pattern, and who don't want to discover mid-build that their flat-UI instincts don't translate to a headset. What you get is a validated interaction model and prototype, tested on real hardware with real users, not a deck of concept renders.

How We’d Approach This

A clear, staged plan — not a black box

  1. 1

    Diagnose the core tasks the spatial interface has to support and which flat-UI patterns won't survive the transition

  2. 2

    Prototype the highest-risk interaction — selection, navigation, or layout — on target hardware to prove it holds up in headset

  3. 3

    Put the prototype in front of real users wearing the device and review where gaze, pinch, or reach breaks down

  4. 4

    Refine into a documented interaction system and hand it off with specs your XR developers can build against

What You Get

Deliverables from this engagement

  • Interaction model and spatial UI specification
