Computing Anywhere, Everywhere : Computing Anywhere, Everywhere “The most profound technologies are those that disappear.”
Mark Weiser, 1991 8/5/2010 1 National Seminar on UC Vasantha Vivek How to make it disappear?
Shrink and embed/distribute it in the physical world
Design interactions that don’t demand our intention

Ubiquitous Computing : Ubiquitous Computing Definitions
Ubiquitous computing is the method of enhancing
computer use by making many computers available
throughout the physical environment, but making them
effectively invisible to the user
– Mark Weiser
Ubiquitous computing, or calm technology, is a
paradigm shift where technology becomes virtually
invisible in our lives.
-- Marcia Riley
(Georgia Institute of Technology, Atlanta.) 8/5/2010 4 National Seminar on UC Vasantha Vivek
Ubiquitous Computing : Ubiquitous Computing "ubiquitous" -"existing or being everywhere at the same time," "constantly encountered," and "widespread."
ubiquitous - technology is everywhere effectively invisible and we use it all the time.
Ubiquitous technology is often wireless, mobile, and networked, making its users more connected to the world around them and the people in it. 8/5/2010 5 National Seminar on UC Vasantha Vivek DEFINITION
