HISTORY First Wave:

Mainframe computing era

Second Wave: Personal computing era

Third Wave: Pervasive computing era

PERVASIVE COMPUTING TECHNOLOGIES

CONNECTIVITY

USER INTERFACE

DEVICES SENSORS

PROCESSORS

ACTUATORS

CONNECTIVITYInterlinking of independent electronic devices into

broader network.

Achieved via:1.Wired Technology2.Unwired Technology

USER INTERFACES Represents the point of contact

between PCS and human users.

Different forms of human-computer interaction are:

1. Active 2. Passive 3. Coercive

HUMAN-COMPUTER INTERACTIONS

ACTIVE: Users can have control over PCT and devices in environment.

PASSIVE: Pervasive computing disappears into background.

COERCIVE: Pervasive computing could control, lives and environment.

ONGOING RESEARCH

Project Oxygen, being pursued by MIT.

Project Endeavour, University of California at Berkeley

CONCLUSION

“ Pervasive computing is roughly the opposite of virtual reality. Where virtual reality puts people inside a computer-generated world, pervasive computing forces the computer to live out here in the world with people”
