OUTLINE
• Background• Challenges• Ideas• Publications• Solutions/Projects
What does this mean?
• Ubiquitous• Pervasive
Semantics
• Ubiquitous: Existing or being everywhere, or in all places, at the same time; omnipresent.
• Pervasive. per- through + vadere to go Tending to pervade, or having power to spread throughout; of a pervading quality.
• Pervasive is a stepping stone to ubiquity.• Does a pervasive technology become
ubiquitous when its taken for granted?
Post Desktop
Active World
• Spectrum of computation and communication devices.
• Seamless augmentation of human thought and activity.
• Enhance users behavioral context in an automated mirror, virtual or mixed world.
Benefits
• The translation of information to/from physical properties.
• The ability to transform data.• The collaborative computational environment
that results from embedding devices in a network.
Ethics
• How do we make sure only good things happen? – Surveillance– Loss of Privacy
• Whether you study pervasive computing or not, this is going to be one of the problems your generation will have to solve.
Rapid Convergence
• Distributed• Networked • Multimedia• Mobile • Embedded computing
• Sensing• Robotics • Multimedia• Wireless communications• The Internet

Active Buildings
• Applications for tours, exhibitions, seminars, lectures, meetings
• Migrating, suspending, resuming sessions of interactive tasks that implement an abstract human activity
• a programmable COTS infrastructure enabling context sensitive applications that allow users to interact seamlessly with a combination of physical and computer facilities.
Challenges for Ubiquitous Computing
• How do we ensure that ubiquitous computing systems fulfill their required and intended purpose?
• How do we ensure that we can trust these systems to perform as intended?
• How do we produce ubiquitous computing systems efficiently and economically?
