We talk with Professor Chris Harrison (director of the Future Interfaces Group) and Professor Scott Hudson (his PhD advisor!) about the evolution of HCI, from its very roots to the dizzying array of fields it touches on today. We discuss the value of research, their personal paths with research, and the variety of work they do today, from novel sensing technologies to computational fabrication.    Links: https://dl.acm.org/doi/10.1145/1622176.1622199 (joint paper for precise + unpowered input on small devices) https://chrisharrison.net/projects/wallplusplus/wallplusplus.pdf (joint paper exploring interactive wall technology)   Chris Harrison’s Work: https://www.chrisharrison.net/ - his website https://chrisharrison.net/projects/wallplusplus/wallplusplus.pdf (skinput - skin based touch sensors) https://dl.acm.org/doi/10.1145/2807442.2807480 (wearable device to detect hand gestures) https://dl.acm.org/doi/10.1145/3351229 (Edusense - smart classroom to provide instructor feedback) https://dl.acm.org/doi/10.1145/3586183.3606771 (fluid reality - tetherless haptic gloves) Scott Hudson’s Work: https://link.springer.com/article/10.1007/s40593-020-00194-3 (Mixed-reality AI system to support education) https://dl.acm.org/doi/10.1145/3563657.3595983 (sustainable 3D printing material from coffee grounds) https://dl.acm.org/doi/10.1145/344949.344959 (2000 paper exploring the future of interface tools) https://dl.acm.org/doi/10.1145/642611.642657 (predicting interruptibility with sensors)
