I am a professor and associate chair, partnerships and innovation, of computer science at the University of Toronto, and the director, research science of Meta’s Reality Labs Research Toronto. My general area of research is the leveraging of computing technology to enable people to live better lives. This work includes the study of human uses of technologies, of basic human needs and capabilities, and the development of technologies to help meet those needs given their capabilities. These technologies include sensing methods, operating system architectures, development platforms, interaction methods, AI systems, and human-AI interaction. Talks about my work in may be found online: haptics & high performance UX, post-WIMP user interfaces, and the symphony of devices.

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.

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.

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

Addem works to build prototyping tools to enable makers and others to instantly print working, copper PCB’s, building on Print’em, developed by my PhD student, Varun Perumal. Addem was founded thanks in part to a startup award from the Connaught Fund. More information may be found at addem.io.

Chatham Labs was acquired by Facebook in 2020. It performed research in partnership with companies seeking to invent the future of human-computer interaction.

Tactual Labs was formed in 2013 to commercialize our work in touch and gestural interface technologies. Today, it has offices in New York, Toronto, Austin, Virginia, Orlando, and Portland, Maine. Tactual Labs brings human sensing to and around every surface. Tactual 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.

Daniel Wigdor is a professor of computer science, conducting his research in the Dynamic Graphics Project at the University of Toronto. He is the Associate Chair for Partnerships and Innovation for the Department of Computer Science, as well as the Director, Research Science of Meta’s Reality Labs Toronto.

His research is in the area of human-computer interaction, with major areas of focus in the architecture of highly-performant UI’s, in interaction and application models for mobile computing, in platform design for ubiquitous computing, and in post-WIMP interaction methods. Before joining the faculty at U of T in 2011, Daniel was a researcher at Microsoft Research, as well as the user experience architect of the Microsoft Surface Table and Microsoft’s Entertainment and Devices division. Daniel has served as a visiting associate professor at Cornell Tech (2017-2018), as an affiliate assistant professor at the University of Washington (2009-2011), and fellow and associate at Harvard University (2007-2008, 2011-2012). He conducted research as an intern at Mitsubishi Electric Research Labs (2005-2008). For his research, he has been awarded an Ontario Early Researcher Award (2014), the Alfred P. Sloan Foundation’s Research Fellowship (2015), and an NSERC Industrial Research Chair (2018), as well as best paper awards or honourable mentions at CHI 2021, CHI 2019, CHI 2018, CHI 2017, CHI 2016, CHI 2015, CHI 2014, Graphics Interface 2013, CHI 2011, and UIST 2004. Three of his projects were selected as the People’s Choice Best Talks at CHI 2014 and CHI 2015.

Daniel is co-founder of Iota Wireless, a startup commercializing his research in mobile-phone gestural interaction, of Addem, a startup commercializing his team’s work in printed circuit board fabrication methods, of Tactual Labs, a startup commercializing his research in novel human sensing, and of Chatham Labs, an HCI research consultancy which was acquired by Facebook in 2020. Daniel is the co-author of Brave NUI World | Designing Natural User Interfaces for Touch and Gesture, the first practical book for the design of touch and gesture interfaces (available in English, Chinese, and Korean). He has also published dozens of other works as invited book chapters and papers in leading international journals and conferences, and is a named inventor on over four dozen patents and pending patent applications. Daniel’s is sought after as an expert witness, and has testified before courts and commissions in the United Kingdom and the United States. Further information, including publications and videos demonstrating some of his research, can be found at danielwigdor.com.
