UbiComp: Habitat for Computers and

HumansDwelling with computers means that they have their place, and we ours, and we co-

exist comfortably. Unfortunately, our existing metaphors for computers [are] inadequate to describe the 'dwelling'

relationship.

UbiCompApplications

Ubiquitous Computing: Impact

• Huge impact on society: good & evil

• Benefits from applications that make our life easier

• Social issues in every single aspect

• Social Behavior– Ubiquitous computing challenges

individuals to rethink their behavior• The Environment

– Environmental issues of mass production/destruction of these devices and energy consumption

• Privacy and Human Rights– Requires continuous monitoring of user

actions

Ubiquitous Computing: Challenges

Strategic Challenges for u-India

• Constituents of e-India are at various stages of implementation (e-Governance, broadband connectivity, rural connectivity, e-commerce, e-Security, e-Learning, e-Health, i-Grid etc)– A Conceptual framework for u-India with time-

frame, objectives and people’s expectations from ubiquitous networks and those of Industry need to be developed concurrently

• Arriving at digital convergent environment & infrastructure integrating broadcasting, communications and Internet– Possibly adoption of open technology and inter-

operable standards in ICT systems

Strategic Challenges for u-India

• Ubiquitous Computing Research Initiatives– Enabling technologies such as wireless sensor

networks, RFID, ad-hoc networks, middleware, context-aware computing and human-computer interaction

• Deeper insights into issues of ubiquitous information society– Needs of elders, trust & privacy, natural calamity

forecast and management system

• Building-up cooperation with countries implementing u-Information Society
