INTRODUCTION n Control over the surrounding environment that is what pervasive computing will mean.

ORGANISATION n n n n HISTORY TECHNIQUES HUMAN-COMPUTER INTERACTIONS APPLICATIONS ONGOING RESEARCH ISSUES CONCLUSION

HISTORY n n n First Wave: Mainframe computing era Second Wave: Personal computing era Third Wave: Pervasive computing era

PERVASIVE COMPUTING TECHNOLOGIES n DEVICES n CONNECTIVITY n USER INTERFACE

DEVICES n SENSORS n PROCESSORS n ACTUATORS

CONNECTIVITY Interlinking of independent electronic devices into broader network. Achieved via: 1. Wired Technology 2. Unwired Technology

USER INTERFACES n n 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 n ACTIVE: Users can have control over PCT n PASSIVE: Pervasive computing disappears n COERCIVE: Pervasive computing could and devices in environment. into background. control, lives and environment.

ONGOING RESEARCH n n n Project Oxygen, being pursued by MIT. Project Endeavour, University of California at Berkeley Project Aura, Carnegie Mellon University

OXYGEN n Approach to invisible computing being pursued by MIT. Ø Vision Ø Challenges Ø Approach

Oxygen device technologies n E 21’S: Intelligent Spaces n H 21’S: Mobile Devices

Oxygen network technologies n Ø Ø N 21’s Collaborative regions Automatic resource discovery Security Adaptation

Oxygen perceptual technologies n n Spoken Interaction Visual Interaction

Oxygen user technologies n Collaboration n Automation n Knowledge Access

DEMONSTRATION

APPLICATIONS n n HEALTHCARE DOMICILIARY CARE

APPLICATIONS (contd. ) n n ENVIRONMENTAL MONITORING INTELLIGENT TRANSPORT SYSTEM

ISSUES n ENGINEERING ISSUES n PRIVACY, SAFETY AND SECURITY n ENVIRONMENT n HEALTH

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”
