IMSC Research Program -- Immersipresence Motivated by Moore’s law: exponential performance growth. . . enables advances towards the future of the internet, grid computing, nano-technology, . . . National Science Foundation Engineering Research Center
People are often the ultimate purpose behind silicon systems In pursuit of an experience, or the performance of a task, or understanding of information Integrated Media System (IMS) mediate the gap between silicon and humans An extension of the human senses, actuators, or cognitive process Our goal is to advance the science and engineering of “well designed” Integrated Media Systems that exploit human information processing capabilities - providing effectiveness that we associate with “immersipresense”. National Science Foundation Engineering Research Center
To better understand immersipresence and help set specific goals, we develop visions of how IMS technologies will affect people and their activities We examine four domains for IMS impacts in the future These four vision scenarios drive the center’s program of six research and engineering areas National Science Foundation Engineering Research Center
