AR/MR/VR EXPERIENCE DESIGN

MICROSOFT | 2015 – PRESENT

At the Mixed Reality Design team, I lead the design effort on the developer & creator ecosystem experience for Mixed Reality, focusing on open-source projects. Our team is working closely with the engineering team to build and share the common spatial interaction patterns and UI controls for Mixed Reality.

As a designer who has an engineering background and published many apps on various platforms, I have deep empathy for the developers and creators. With this, I help the team integrate and realize the design vision by polishing the visual and interaction design of the controls, creating example scenes that demonstrate the building blocks, and writing design & technical guidelines. I enjoy every moment of my work as a designer who can connect design and engineering.

2D UX DESIGN

MICROSOFT | 2011 – 2015

As a UX designer, I worked with engineers, program managers, and user researchers to design the best content consumption experience for Microsoft’s MSN/Bing Apps on various platforms – News, Weather, Sports, Finance (Money), Travel, Health & Fitness, Food & Drink apps for Windows, iOS, Android, and web. In a small design team of 5-10 people, I was responsible for the entire design process – ideation, sketching, prototyping, information architecture, navigation, data visualization, interaction design, visual design, and branding.

As a designer with engineering experience, I established a deep collaboration relationship with the engineering team. I drove hands-on design integration to achieve the pixel-perfect design in the production phase. By several media, Bing/MSN app suites were considered as the best Windows apps that showcase Microsoft’s new Metro design language with rich content and fluid user experience.

Focus Areas
• Visual design
• Interaction design
• Information architecture
• Navigation
• Common UX
• Motion design
• Prototyping
• Design integration
