In 2017, Robert Xiao, an HCII PhD student, along with Harrison and Scott Hudson, his advisors, created Desktopography, 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. Harrison co-developed and co-wrote 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. Along with Robert Xiao and Scott Hudson, colleagues at CMU, he developed Lumitrack, a motion tracking technology which is currently used in video game controllers and in the film industry. Harrison was also one of the Program Committee Chairs for the 2017 ACM Symposium on User Interface Software and Technology (UIST). Chris is also an amateur digital artist and sculptor. His artworks have appeared in over 40 books and more than a dozen international galleries. Notable among these appearances were showings at the Triennale di Milano in Milan, Italy (2014), and the in Saint-Étienne, France (2010).
