Ubiquitous Computing and
C-DAC's initiative

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
