Yoon Park is a Principal Designer and creative technologist with over a decade shaping spatial input and interaction for Meta Quest, Horizon OS, and previously Microsoft HoloLens. He blends design and engineering expertise to lead interaction SDKs, design systems, and open-source tooling—most notably contributing to the Mixed Reality Toolkit (MRTK) used across the spatial computing community. His background spans mobile UI and systems work at Samsung to design leadership at Microsoft, giving him rare fluency in both low-level implementation and high-level design language. An author of best-selling iOS programming books in Korea and creator of TypeInsight, he pairs published thought leadership with hands-on coding and UI polish. Based in Redmond and originally from Seoul, he is recognized among “30 People To Watch In Augmented Reality” for shaping common spatial interaction patterns. He often bridges research, developer ecosystems, and product teams to turn experimental input modalities into shipping developer platforms.
