Data Blanket – Real-time AI-Driven Fire Fighting
Wildfires result in the loss of thousands of lives, millions of acres, hundreds of billions of dollars in damage, and over 5% of global emissions every year. Doing better should be everybody’s business We just made it ours by building the most comprehensive system out there, empowering our firefighters with new tactical tools and information, and ensuring every part of this fighting system performs better.
2011-2023 Principal Researcher & Research Manager
I was a Principal Researcher in the EPIC (Extended Perception Interaction and Cognition) team at Microsoft Research. My research focused on Human-Computer Interaction (HCI) and sensing and Mixed Reality displays (MR) to enable users to reach their full potential in productivity, creativity, and collaboration. I have been granted more than 110 patents and published over 90 academic publications (with more than 14000 citations), and I was awarded a senior member of Assoc. for Computing Machines (ACM).
In addition to publications and transfer of technology to products, I have released multiple tools and open source libraries such as the RoomAlive Toolkit, used around the world for multi-projection systems, SeeingVR to enhance the use of VR for people with low vision, Microsoft Rocketbox avatars, MoveBox and HeadBox toolkits to democratize avatar animation, and RemoteLab for distributed user studies.
Besides my work at Microsoft Research, I served on multiple conference committees and was the paper chair of ACM SIGSPATIAL 2011. I was the Specialty Chief Editor of Frontiers in Virtual Reality for the area of Haptics and on the editorial board of IEEE Computer Graphics and Application Journal (CG&A).
I have formed and led a new MR research group at Microsoft Research’s Extreme Computing lab. I envision MR applications as weaved with the fabric of our lives rather than PC and mobile apps, limited to running on a specific device’s screen. Such applications have to be smart to understand users’ changing physical and social context and flexible to adapt accordingly. We developed systems such as FLARE (Fast Layout for AR experiences) that were used by the HoloLens Team and inspired the Unity MARS product, or Triton 3D audio simulation used by Microsoft Games such as Gears of War 4 and is the base of Microsoft Acoustics. ILLUMIROOM, a collaboration with the Redmond Lab, was presented at CES 2013 Keynote.
2005-2011 Research Manager
I formed the Bing Maps & Mobile Research Lab (Virtual Earth Research). We combined generated many novel results, impacting the product while generating world-class computer vision and graphics research. Among our results is the development of the influential text detector technology used by the BIng Mobile app and incorporated into OpenCV, the world’s first street-side imagery service, street-level reconstruction of geometry and texture pipeline, novel texture compression used by Virtual Earth 3D, and more.
Besides publishing in leading computer vision and graphics forums, our work was presented at TED 2010 and in the New York Times.
1996-2001 CTO (Software)
I oversaw software and algorithms R&D of the world’s first time-of-flight video camera in a startup company. I used cameras for applications such as TV depth keying and reconstruction, and it was the basis for the Depth cameras used by Microsoft HoloLens and MagicLeap HMD.
1995-1996 Interactive Innovation – Founder
Development of a novel game engine rendering global illumination effects in real-time. The work was presented at SIGGRAPH 1996 and appeared in graphic textbooks.
1992-1996 The Hebrew University of Jerusalem, Israel
Ph.D. in Computer Vision and Computer Graphics.
I received my M.Sc. in Computer Vision in 1992 and a Triple Major BA (Computer Science, Physics, & Mathematics) in 1987.
1985-1986 Bazbosoft –Founder
Development of the award-winning and super popular Amiga photo-editing and drawing editor (Photon-Paint).

Research Interests
Adaptive Mixed Reality (MR) & AI
I see Mixed reality as a revolution beyond display technology. While traditional software is developed, tested, and used on standard devices, MR applications use the user environment as their platform. This requires such applications to be aware of the user’s unique context, physical environment, social interactions, and other applications. The rise of Machine Learning and large language models is an exciting opportunity to incorporate more localized and global knowledge into this process.
I look at new ways to design and implement such applications and their effect on our work and social interactions.
Sensing, Computer Vision, and privacy
Another aspect of the technology revolution is the proliferation of sensors, enabling applications to fit the user’s context and intent better. Sensors can enable better interaction with devices as part of a holistic digital environment around the user, all focused on the user’s tasks and enabling a bridge between digital space and physical objects.
A significant importance I see in designing sensing is that it can enable new capabilities but maintain the user’s privacy. New sensors enable us to plan what part of the space is measured and use the minimalistic data granularity needed for the task.
Accessibility and inclusion of MR
Today we can augment our senses in a way that enables us to be in a digital space, independent of the physical laws that limit us in Reality. It enables people to do more than they could have achieved in reality. It also enables to level the plane field between users with different physical, social, or environmental limitations.
Haptics
Our experience of the real world is not limited to vision and audio. The limited rendering of touch sensation reduces MR’s realism today and the effectiveness of using our hands when working in the space.
I have done extensive research on rendering haptics with other senses, designing novel hand-held haptic controllers that advanced the state-of-the-art of active haptic rendering and using scene understanding and manipulation of hand-eye -coordination effects of using the physical environment around the user for haptic rendering.
Avatars
In Virtual Reality and spatial computing simulations, avatars often represent humans.
I was working on issues such as creating avatars, controlling avatars using natural motions, and decoupling avatars’ motions from users’ motions for accessibility and productivity and their perception by the users.
