This document discusses the history and future of human-computer interaction (HCI) from different perspectives. It covers tangible, mobile, wearable, and natural user interfaces. For each type of interface, it provides examples of projects from conferences like CHI and UIST that pioneer new interaction techniques. The document suggests interaction will continue moving beyond screens to incorporate physical and embodied interactions using technologies like Leap Motion, Project Soli, and supportive robots. It questions how objects can better communicate with humans.
