I led the overall UX design of the MRTK’s building blocks, examples, assets, and documentation. In this process, I closely worked with the engineering team and program managers to prioritize UX items and triage bugs based on internal/external customer’s needs.


  • Led the design of MRTK’s UX building blocks
  • Helped the team to validate hand tracking APIs by building prototypes
  • Updated existing UI controls and interactions to support near interaction with hand tracking & far interaction with hand-ray
  • Created various example scenes to accelerate design and development of the HoloLens 2 applications
  • Worked with the engineering team to ensure MRTK’s building blocks are extensible, modular and people can easily customize and infuse own brand identity
  • Created test scenes for the near interaction user research studies
  • Polished the visual and interaction design of the controls
  • Submitted & reviewed Pull Requests on Visual Studio Online and GitHub
  • Created documents that explain technical details and design guidelines
  • Created videos with Mixed Reality Capture to promote new features
  • Engaged with the developer community through multiple channels including GitHub, Slack, and Mixed Reality Academy
  • Worked with multiple partner companies and helped them to update HoloLens v1 apps to support new interactions
