Bill Buxton and Brad MyersGuest Lecture #1: Bill Buxton, Partner Researcher at Microsoft Research

Video of Bill Buxton talk and automatic transcript

Bill Buxton is a relentless advocate for innovation, design, and - especially - the appropriate consideration of human values, capacity, and culture in the conception, implementation, and use of new products and technologies.  This is reflected in his research, teaching, talks, and writing - including his past column on design and innovation for BusinessWeek.com, and his 2007 book, Sketching User Experiences. He is a Partner Researcher at Microsoft Research, where he has been employed since December 2005. He was on the faculty in the Computer Science Department at the University of Toronto, where he continues to have an Adjunct Professor appointment. From 1987-89, Buxton was in Cambridge England, helping establish a new satellite of Xerox's Palo Alto Research Center (EuroPARC). From 1989-94 he split his time between Toronto, where he was Scientific Director of the Ontario Telepresence Project, and Palo Alto, California, where he was a consulting researcher at Xerox PARC. From 1994 until December 2002, he was Chief Scientist of Alias|Wavefront, (now part of Autodesk) and from 1995, its parent company SGI Inc.

    (Note: Game Feel is written by a game designer rather than a traditional HCI practitioner, so he doesn't practice the formal study of interaction techniques. Think about how our class techniques and his approach relate as you're reading. Because he is a game designer, he may reference video games in passing with which you may be unfamiliar. If you're interested, YouTube is filled with demo videos that can show you what the game looks like and how it plays, especially if you add "review" or "gameplay" to your search.)

Julia Schwarz builds software that leverages probabilistic modeling, signal processing, and machine learning to improve user interfaces. She received a BS from University of Washington, and a PhD from Carnegie Mellon University. At Carnegie Mellon she co-founded Qeexo, where she led the team that developed FingerSense, currently shipping on over 300 million Huawei devices. In 2015 she moved back home to work on the HoloLens team at Microsoft. At Microsoft, she brought instinctual interactions to HoloLens 2, allowing users to directly interact with holograms using their hands.
