Yoon Park is a principal product designer and design technologist specializing in spatial input, interaction systems, and developer platforms. At Meta Reality Labs, he leads platform-level design across Meta Quest and Horizon OS, shaping how multiple input modalities work together as one coherent general-purpose computing system.
His practice combines interaction design, visual systems, prototyping, and hands-on implementation. He turns emerging research into shippable platform capabilities and aligns design, engineering, research, product, documentation, and partner teams around shared principles and quality bars.
After majoring in electrical engineering and working as a software engineer at Samsung Electronics, he returned to school to study graphic design at SADI (Samsung Art & Design Institute) and later continued at Parsons School of Design in the MFA Design & Technology program. His MFA thesis project, Typography Insight (typeinsight.org), was featured by Fast Company, The Atlantic, and Gizmodo, and ranked second in the Education category on the U.S. App Store. With his growing interest in mobile design and development, he authored the book 도전! 아이폰 프로그래밍 (Challenge! iPhone Programming), which became a best-selling iPhone programming book in Korea from 2011–2012.
Yoon joined Microsoft in 2011, first shaping content-rich MSN and Bing experiences across Windows, iOS, Android, and the web. As lead designer for the Sports and Finance apps, he helped define scalable information architecture, interaction patterns, and visual systems within Microsoft’s Metro design language. In 2015, his focus expanded to developer experience and spatial computing.
In 2016, Yoon joined the Mixed Reality design team for HoloLens and Windows Mixed Reality, leading the design of ecosystem experiences such as the open-source Mixed Reality Toolkit (MRTK), Mixed Reality Design Labs (MRDL), Mixed Reality Academy, and Mixed Reality Dev Center.
Yoon joined Meta Reality Labs in 2023, where he leads the exploration and productization of the general-purpose computing input stack, including hands, eyes, voice, controllers, stylus, keyboards, gamepad, mouse, and microgestures. His independent work, beginning with the HoloLens app Type In Space, continues to ground his platform thinking in direct product-making experience.
Most recently, he launched Cosmic XR, a Mixed Reality app inspired by his passion for space, data visualization, and spatial interaction. Cosmic XR was featured by UploadVR and received the Top Rated badge on the Meta Quest Store, and won The Polys 6th Annual Immersive Awards, Education Experience of the Year, recognized for its educational value, immersive design, and emotional impact on users around the world.
In June 2026, he published Spatial Computing: XR Interaction Design (공간 컴퓨팅: XR 인터랙션 디자인), sharing over a decade of practical experience designing XR interactions, interfaces, and spatial computing products.
