IVY PROJECT

• Principal goal is to provide a research sensor
  network infrastructure
• 1 year lifetime on 2 AA batteries
• Sensor nodes send connectivity information and
  sensor data
• Data logged to a database
• Web user interface to database

ELECTRONIC CULTURAL ATLAS INITIATIVE

• Founded in 1997
• ECAI is a global community dedicated to enhancing
  digital scholarship and cultural heritage
  preservation by using time and space for data
  sharing
• Collaboration with CITRIS
• Global consortium of over 700 humanities scholars
  and IT researchers

heritage information
Dynamic map containing information on Iraq and
its neighbors
27
ECAI AND THE HUMANITIES

• Allows spatial and temporal discovery and
  analysis
• A clearinghouse of over 1000 spatial datasets and
  authored maps. Records are coded by time and
  place and are visable on a map.
• Lets scholars show their work
• Digital atlases that bring together data from
  many contributors pertaining to a given place.

• Facilitates interactive publication
• ePublications are exemplary map-based electronic
  publications on cultural topics. ECAI
  ePublications are peer reviewed and persistent.

28
INFORMATION COMMUNICATIONS TECHNOLOGY FOR
BILLIONS (ICT4B)

• Create and demonstrate enabling ICT
  infrastructure for developing world
• Key deliverables
• Low cost low power devices and displays
• Intermittent connectivity networking
• UI toolkit for low-literacy populations
• Codesign of infrastructure and devices,
  system-on-chip to get 10-100X cost reduction
• At least 2 deployments with apps (e.g. health,
  e-gov, commerce)

29
Experimental Social Sciences Lab at UC Berkeley
( X-LAB)
Conducts experiments that explore the interface
between economics and psychology as they affect
individual and group decision-making.

• What is experimental economics?
• Pay subjects real money to participate in
  economic institutions such as
• Auctions
• Markets
• Bargaining
• Decision making (individual and group)
• Etc, etc
• Used to test economic theories, teach economic
  principles, design economic institutions

CITRIS LONG-TERM GOALS

• Continue to develop, test, and promote large
  societal scale information systems that are
  heterogeneous, reliable, maintainable, cost
  effective, and easy to use
• Build bridges to new application areas and expand
  reach into more communities
• Seed new research
• Increase Institute impact in academia and
  industry and visibility in public and media
  arenas
