• Always-on connectivity (3G/4G/LTE)• Short-range wireless for consumers

– Bluetooth, WiFi (802.11a/b/g/n)

• Body Area Networks– Transmit data thru the body

Ubiquitous Computing is Coming All Wirelessly Connected

• These are the tech trends, but quo vadis?– What do we really want ubicomp to be?

– What’s the “right” way to do it?

• Many different issues– Interaction design, systems, HCI, public policy, privacy…

– Different communities, different vocabulary, different papers

• Goals of this course– Discuss and understand these issues

– Help advance state of the art

Just Where Are We Heading?

• Readings– Every class will be several readings

(about two papers)– At beginning of class, turn in summary of

each paper• 3-8 sentences plus a highlight• Something interesting or noteworthy• A question to discuss in class• A point you disagree with

• Final exam (in-class)– Based on about 10 selected papers out of

the reading list (e.g., one paper per topic)

Structure of this Course

• Course project– Do a piece of substantial research

– Teams of 2-3

– “Conference paper” as deliverable

• Kinds of projects– Design-oriented

– Implementation-oriented

– Evaluation-oriented

– Mixture of above

Structure of this Course

• Visions/challenges in mobile and pervasive computing

• Context-aware computing: localization and activity detection

• Naming and service discovery in mobile computing

• Mobile data access (distributed file systems and content centric networking)

• Energy management

Overview of Course Topics

• Audio/image processing• Privacy• Smart homes• Mobile content distribution• Participatory sensing• Vehicular sensing• Infrastructure monitoring• Vehicular applications

• Readings for next class– The Computer for the Twenty-First Century, Mark Weiser,

by Mark Weiser

– Beyond Prototypes: Challenges in Deploying Ubiquitous Systems, by Nigel Davies and Hans-Werner Gellersen

Next Class

Important Questions to Think About

• Original vision of ubicomp written in 1991!– Why haven’t we achieved it yet?

• How to manage this complexity?– Things barely work together today

– Overload of information

• What are the core devices?– Buy it at Hi-Mart, plug it in, and you’re good to go!

• What are the core services of this world?– Equivalent of Google, Yahoo, and eBay?

• Is this really a world we want to live in?
