Overview

Reality Composer enables users to build AR experiences without deep technical knowledge.

The challenge was to design a 3D interaction system that is intuitive, precise, and scalable.

I led the design and implementation of core 3D UI and interaction mechanics, shipped across iOS and macOS.

My Role

UX Research Lead / Technical Designer

  • Designed 3D interaction systems

  • Implemented real-time prototypes

  • Conducted usability evaluations

  • Collaborated across product, design and engineering


The Challenge

3D manipulation introduces cognitive and perceptual complexity. Users struggle with:

  • Depth understanding

  • Precision control (translate, rotate, scale)

  • Lack of clear feedback during interaction

  • High cognitive load

Approach

We focused on direct manipulation and continuous feedback.

Principles:

  • Visible, interactive controls

  • Real-time response

  • Consistent interaction patterns


What I Built

  • 3D transformation system (translate, rotate, scale)

  • Visual gizmos for direct manipulation

  • Real-time feedback for positioning and alignment

  • Lighting and scene controls

User Research

Through usability testing and iterative prototyping, we identified key friction points.

Insights:

  • Visual cues are essential for depth

  • Responsiveness defines usability

  • Complexity reduces adoption

  • Interaction delays break the sense of control

Impact

  • Shipped as part of Reality Composer on iOS and macOS

  • Enabled developers and designers to prototype AR experiences visually

  • Reduced barrier to entry for spatial content creation

  • Adopted by a broad range of users from beginners to advanced creators


Reflection

Good 3D tools reduce complexity without removing control. By focusing on clarity, feedback, and consistency, we turned a technically complex process into an approachable creative tool.
