Chris Harrison is an English-born, American computer scientist and entrepreneur, working in the fields of human-computer interaction, machine learning and sensor-driven interactive systems. He is an assistant professor at Carnegie Mellon University[5] and director of the Future Interfaces Group[6] within the Human-Computer Interaction Institute. He has previously conducted research at AT&T Labs, Microsoft Research, IBM Research and Disney Research. He is also the CTO and co-founder of Qeexo,[7] a machine learning and interaction technology startup.

Harrison has authored more than 60 peer-reviewed papers, 25 patents, and his work appears in more than 40 books.[8] For his contributions in human-computer interaction, Harrison was named a top Young Scientist by the World Economic Forum (2014),[2] one of six innovators to watch by Smithsonian (2013),[9] a top 30 scientist under 30 by Forbes (2012),[3] and a top 35 innovator under 35 by MIT Technology Review (2012),[4] among many honors. Most recently, Harrison and his students won a Fast Company Innovation by Design Award for their work on EM-Sense.[10] Over the course of his career, Harrison has been awarded fellowships by the Packard Foundation, Google, Qualcomm and Microsoft Research.

Biography

Harrison was born in 1984 in London, United Kingdom, but emigrated with his family to New York City in the United States at a young age. As an adolescent, Harrison was already very high-achieving and involved in various activities. On September 29, 2001, he attained Eagle Scout status, and the date was deemed "Chris Harrison Day" in this home town. Moreover, Harrison actively participated in the ACM programming competitions, tinkered around with creating several computer games in his spare time, and engaged in a variety crafts, such as engineering, crafting chainmail, and building a trebuchet. He also displayed an interest in Slinging and was contacted for this hobby by BBC for a sling documentary. Consequently, Harrison created and launched Slinging.org on March 20, 2003 as an online forum for sling enthusiasts, which currently has over 200,000 posts.[11] Harrison obtained his citizenship in the United States on May 13, 2002.[12]

Harrison obtained both a B.A. (2002-2005) and M.S. (2006) in Computer Science from the Courant Institute of Mathematical Sciences at New York University, completing both degrees early. His Master's thesis was advised by Dr. Dennis Shasha, with whom he worked on a relational file system built around the concept of temporal context. New York University honored Harrison as its 2014 Distinguished Young Alumnus.

During his master's studies, Harrison worked at IBM Research - Almaden on an early personal assistance application called Enki under Mark Dean, the then-director of the lab. After completing his master's degree, Harrison worked at AT&T Labs, developing an asynchronous social television platform dubbed CollaboraTV. Encouraged by research colleagues, Harrison joined the Ph.D. program in Human-Computer Interaction at Carnegie Mellon University in 2007, completing his dissertation on "The Human Body as an Interactive Computing Platform" in 2013 under the supervision of Dr. Scott Hudson.

From 2009 to 2012, Harrison was the Editor-in-Chief of ACM's Crossroads magazine, which he relaunched as XRDS, the flagship magazine for the over 30,000 student members of the ACM. Harrison also spun-off several technologies out of CMU to cofound the technology startup Qeexo in 2012, which provides machine-learning based interaction technique software for tens of millions of handsets worldwide as of 2016.

In 2013, Harrison became faculty at Carnegie Mellon University, founding the Future Interfaces Group within the Human-Computer Interaction Institute.

Research

Harrison broadly investigates novel sensing and interface technologies, especially those "that empower people to interact with small devices in big ways". He is best known for his research into ubiquitous and wearable computing, where computation escapes the confines of today's small, rectangular screens, and spills interactivity out onto everyday surfaces, such as walls, countertops and furniture.[13] This research thread dates back to 2008, with Scratch Input appropriating walls and tables as ad hoc input surfaces. Insights from this work, especially the vibroacoustic propagation of touch inputs, led to Skinput being developed while Harrison was visiting Microsoft Research.[14][15] Skinput was the first on-body system to demonstrate touch input and coordinated projected graphics without the need to instrument the hands. This research was followed shortly after by OmniTouch, also at Microsoft Research.

More recently, Harrison has been conducting research at the Future Interfaces Group[16] in the Human Computer Interaction department of CMU. In 2016, Harrison presented 3 topics at the ACM Symposium on User Interface Software and Technology (UIST) through Future Interfaces Group. These topics were: using a high speed mode of a smartwatch's accelerometer to acquire and interpret acoustic samples at 4000 samples per second,[17] using electrical impedance sensing to create a real-time hand gesture sensor,[18] and using infrared sensors on a smartwatch to recognize and utilize hand gestures made on the skin directly around the smartwatch.[19] In 2017, Robert Xiao, an HCII PhD student, along with Harrison and Scott Hudson, his advisors, created Desktopography,[20] an interactive multi-touch interface that is projected onto a desktop surface. Inspired by the Xerox PARC DigitalDesk, one of the first digitally augmented desks of its time, Desktopography explores the possibilities of virtual-physical interactions and deals with how to best create a user-friendly interface which has to navigate around various, constantly moved objects, as commonly found on one’s desktop surface.

In order to achieve this, his team conducted an elicitation study and derived a list of ten fundamental interactive behaviors that responsive desk-bound virtual applications should exhibit. They built a proof-of-concept system to support each behavior that can be achieved in real time. The system does not require any calibration and its touch tracking distinguishes human body parts from other objects. These advancements off of previous work are crucial for the system to respond to user movement differently from changes to the physical environment. For example, interfaces should evade from your coffee mug, but not from your hands.

For his research, Harrison has won multiple best paper awards and other accolades. Harrison is also known for his work on post-multitouch input methods for touch screens.

Other activities

Harrison co-developed and is currently co-writing Crash Course Computer Science, a PBS Digital Studios-funded educational series hosted on YouTube. This project was initiated following a discussion between Harrison and John Green at the World Economic Forum in 2016, where both were guest speakers.

Harrison was also one of the Program Committee Chairs for the 2017 ACM Symposium on User Interface Software and Technology (UIST).[21]

Chris is also an amateur digital artist and sculptor. His artworks have appeared in over 40 books and dozens of international galleries. Notable among these appearances were showings of his work at the Triennale di Milano in Milan, Italy (2014), and the Biennale Internationale Design in Saint-Étienne, France (2010).
