About Me

I am a senior researcher at Microsoft Research in the field of Human Computer Interaction. My interests include augmented and virtual reality, interactive projection mapping, haptics, new input form factors and devices, as well as touch and freehand gestural input.

I am passionate about creating highly interactive real-time demonstration systems that highlight the core innovations while at the same time surprising and delighting the user. In my work, I try to strike a balance between long horizon research and solutions that are directly applicable to products in the near term.

I have been active in the Human-Computer Interaction research community and I have had the pleasure of serving on various program committees (CHI, UIST, SIGGRAPH, ISMAR, ITS/ISS). I was the general chair for ACM UIST 2014 and the program chair for ACM UIST 2012. I am currently on the ACM UIST steering committee and on the advisory board for SmartHaptics. I am also the Information Director and Associate Editor for ACM TOCHI journal, the premier journal in my field.

At Microsoft, I have had the priviledge of working on several projects that were released as Microsoft products or as open-sourced projects, including Microsoft Touch Mouse, Windows Touch Visualizations, and RoomAlive Toolkit. I am also one of the founders of studio99, a magical group of artists-in-residence and scientists working together to inspire new ways of thinking at Microsoft.

Research Highlights

Interactive Projection Mapping

I am fascinated with the possibility of using cameras and projectors to embue the space with interactivity. Such projector+camera combinations can enable both data visualization and interactivity without requiring the user to wear any additional gear. Our solutions allow for projection mapping view-dependent perspective content on top of dynamically changing background scenes.

Augmented Reality / Virtual Reality / Haptics

I am interested in creating experiences in AR/VR that enable people to be more than simple observers: to touch, play with and experience the world around them. Haptics offer an interesting channel for input and output that provides a visceral and highly realistic experience. Furthermore, I am also fascinated how we can exploit some perceptual illusions to create a better interactive experience.

Multitouch & Pen Input Devices

Current computer input devices are well optimized input solutions, but they often offer very limited bandwith for interacting with computers. For example, very few devices really take advantage of the full dexterity of the user's hands. My projects have investigated extending the interaction vocabulary of several standard input devices (e.g., mice, pens, and spartphone touchscreens) through multi-touch sensing embedded on the surface of the device. Not only are such multi-touch devices capable of both standard operation and multi-touch gestures, but they can also implicitly sense a lot of contextual information about their use (e.g., whether the user is right or left handed). One of our ideas about multitouch mice made it from a research concept into a product (Microsoft Touch Mouse).
