Daniel Wigdor is an entrepreneur, investor, and professor in the field of computer science. He specializes in the invention of technologies which are tailored to enable people to live better/happier/more productive lives. His innovations have included novel sensing technologies, operating system architectures, AI systems, manufacturing methods, haptic feedback devices, and software systems, all based on his teams’ deep study of human capabilities and needs, employing methods from fields such as psychophysics, sociology, and anthropology. He has founded several companies which have combined to employ hundreds of people across the US and Canada, raising over $100M in revenue and funding. In 2020, he sold Chatham Labs to Facebook, and became the founding director of Meta’s Reality Labs in Toronto. Daniel’s technologies may be found in more than a billion devices worldwide. He holds over 50 patents, has published more than 100 peer-reviewed papers, has written books which have been translated into multiple languages and used as standard texts around the world, and has testified as an expert witness in courts in the US and UK, helping to resolve disputes regarding more than $10B.

Daniel has won many awards for his research, including the Alfred P. Sloan Foundation’s Research Fellowship, the Ontario Early Researcher Award, and more than a dozen ‘best paper’ awards at top venues in computer science. He is currently a professor and is the associate chair for industrial partnerships at the University of Toronto. He has previously held positions at Cornell, the University of Washington, Harvard University, Mitsubishi Electric Research Labs, Microsoft Research, and Reality Labs Research.

Departure from Meta

I have completed my tenure as Director, Research Science of Meta’s Reality Labs Research Toronto as of last week. I am excited to have only one research group to focus on, for the first time since the founding of Tactual Labs in 2013. I also look forward to resuming my much-missed hobby of assisting the courts as an expert witness in user-facing information technologies.

Campus change to downtown St George

Since I first joined U of T in 2011, I have split my time between the downtown Toronto campus (for graduate teaching and my research lab in the dgp) and the Mississauga campus (for undergraduate teaching). I have now fully relocated to the downtown, St George campus. I myself am an alumnus of the downtown Department of Computer Science, and am very much looking forward to being more wholly a part of it. Many thanks to the folks at Mississauga for your help and support over the last decade. I will miss my wonderful interactions with you all.

Promoted to “full” professor

STUDENTS

I mentor graduate and undergraduate students, as well as postdoctoral fellows, who are passionate about inventing the future of human-computer interaction. Undergraduates are typically engineering students conducting thesis work, CS students enrolled in project courses, or USRA or UTRECS scholarship recipients conducting summer research. My graduate students come from diverse backgrounds, but share a record of academic excellence and demonstrated passion for invention. If you are looking for research opportunities: first, review my team’s research. If it piques your interest, contact me to set-up a time to discuss your interests.

Recent Startups

My group at the University of Toronto occasionally spins-out companies to commercialize our work and otherwise participate in industry. Two such spin-outs are presently operating:

Chatham Labs was founded in 2018 to solve the ‘last mile problem’ of tech transfer from the research lab to integrated product-ready technologies, in partnership with leading-edge clients in the IT industry. Our projects included applied AI for real-time systems, user interface software and hardware, and operating system architectures for embedded AI. Chatham Labs was acquired by Facebook in 2020, and is now Reality Labs Research Toronto.

Tactual Labs was formed in 2013 to commercialize our work in touch and gestural interface technologies. Tactual brings human sensing to and around every surface: its technology surrounds flat or free-form objects with accurate, real-time in-air, skeletal and contact sensing. Tactual technology “sees” the human hand and body in 3D from every point on an object’s surface. Tactual solutions are deployed to development partners, empowering digital platforms across a variety of markets including mixed reality, surface computing, mobility, automotive, consumer electronics, and robotics. More information may be found at TactualLabs.com.

Expert Witness for User Interface Technology

Areas of Expertise: User interfaces (computers and other IT devices), user interfaces for AI, input devices, input techniques, interaction methods, text entry methods, mouse input, touch input, pen input, gesture input, gesture recognition, touch screens, smartphones, tablets, tabletops, mobile devices, mobile computing, virtual reality, augmented reality, mixed reality, haptic, and other output technologies.

Experience: I have completed work as an expert witness on 36 legal disputes, including both insurance liability and intellectual property cases related to patent infringement and validity in the field of user interface technology. I have filed numerous expert reports and IPR declarations, and have been deposed ten (10) times, and testified at trial five (5) times in US district court, in ITC hearings, and in the High Court of Justice in Great Britain.

I am an inventor on more than 50 issued US patents and have authored over 100 peer-reviewed academic papers. My book, Brave NUI world, is used to teach innovative human-computer interaction at top schools around the world. I have founded numerous companies, and have served as a research director at Meta after it acquired one of them. Technologies I have invented may be found in more than a billion devices worldwide. See my publications and my bio. for more information.
