Light Switch 1.0 Light Switch 2.0 Invisible Computing Actual - Fact Functional - Metaphor Hammer "Such a disappearance is a fundamental consequence not of technology but of human psychology" Metaphors Computers as writing literacy as required training paper, ink, pens as infrastructure Implications for ownership and cost text as ubiquitous information Computer as clothing Seamless Flowing Are these good metaphors?

Representational Forms of the world Situational Forms of the world Planning vs. Reacting Technological Role in the construction of space "The hundreds of processors and displays are not a "user interface" like a mouse and windows, just a pleasant and effective "place" to get things done" Anachronism "Telephone calls can be automatically forwarded to wherever the recipient may be" "Some industry observers believe that this exponential growth in raw chip speed may begin to level off about 1994 but that other measures of performance, including power consumption and auxiliary functions, will still improve."
