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

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?
