Spatial Computing is the fourth paradigm, and we see it as the most personal of all the personal computing paradigms yet to come. We will cover six technologies that enable Spatial Computing to work: Optics and Displays, Wireless and Communications, Control Mechanisms (Voice and Hands), Sensors and Mapping, Compute Architectures (new kinds of Cloud Computing...
