I am a senior researcher in Natural Interaction Research group at Microsoft Research. My research is in the field of Human Computer Interaction. My interests include:

  • augmented and virtual reality,
  • haptics,
  • interactive projection mapping,
  • new input form factors and devices,
  • 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.

Sparse Haptic Proxy

Established: May 4, 2017

  The user of Virtual Reality, may find himself in different virtual worlds, such as a spy game (middle) or a space simulator(right) , yet they all give him tangible feedback using the same physical geometry in the real world (left). We propose a class of passive haptics that we call Sparse Haptic Proxy: a set of geometric primitives that simulate touch feedback in elaborate virtual reality scenes. Unlike previous passive haptics that replicate the…

Enhancing Input On and Above the Interactive Surface with Muscle Sensing

Current interactive surfaces provide little or no in-formation about which fingers are touching the surface, the amount of pressure exerted, or gestures that occur when not in contact with the surface. These limitations constrain the interaction vocabulary available to interactive surface systems. In our work, we extend the surface interaction space by using muscle sensing to provide complementary information about finger movement and posture. In this paper, we describe a novel system that combines muscle…

Muscle-Computer Interfaces (muCIs)

Established: November 28, 2016

Many human-computer interaction technologies are currently mediated by physical transducers such as mice, keyboards, pens, dials, and touch-sensitive surfaces. While these transducers have enabled powerful interaction paradigms and leverage our human expertise in interacting with physical objects, they tether computation to a physical artifact that has to be within reach of the user. As computing and displays begin to integrate more seamlessly into our environment and are used in situations where the user is not…

Room2Room: Life-Size Telepresence in a Projected Augmented Reality Environment

Established: March 2, 2016

Room2Room is a life-size telepresence system that leverages projected augmented reality to enable co-present interaction between two remote participants. We enable a face-to-face conversation by performing 3D capture of the local user with color + depth cameras and projecting their virtual copy into the remote space at life-size scale. This creates an illusion of the remote person’s presence in the local space, as well as a shared understanding of verbal and non-verbal cues (e.g., gaze).

Dyadic Mano-a-Mano

Established: October 3, 2014

Mano-a-Mano is a unique spatial augmented reality system that combines dynamic projection mapping, multiple perspective views and device-less interaction to support face-to-face, or dyadic, interaction with 3D virtual objects. Its main advantage over more traditional AR approaches is users are able to interact with 3D virtual objects and each other without cumbersome devices that obstruct face to face interaction.

RoomAlive is a proof-of-concept prototype that transforms any room into an immersive, augmented, magical entertainment experience. RoomAlive presents a unified, scalable approach for interactive projection mapping that dynamically adapts content to any room. Users can touch, shoot, stomp, dodge and steer projected content that seamlessly co-exists with their existing physical environment.

IllumiRoom: Peripheral Projected Illusions for Interactive Experiences

Established: January 4, 2013

IllumiRoom is a proof-of-concept system from Microsoft Research. It augments the area surrounding a television screen with projected visualizations to enhance the traditional living room entertainment experience.         Read the CHI 2013 Best-Paper: IllumiRoom: Peripheral Projected Illusions for Interactive Experiences (7.6 MB .pdf) IllumiRoom uses a Kinect for Windows camera and a projector to blur the lines between on-screen content and the environment we live in allowing us to…


Established: October 2, 2010

LightSpace combines elements of surface computing and augmented reality research to create a highly interactive space where any surface, and even the space between surfaces, is fully interactive. Our concept transforms the ideas of surface computing into the new realm of spatial computing. Instrumented with multiple depth cameras and projectors, LightSpace is a small room installation designed to explore a variety of interactions and computational strategies related to interactive displays and the space that they…
