Motivation and Goals

• Exploiting IT to enhance understanding
• Significantly more convenient for people to
  interact with information, devices, and other
  people than todays systems
• Pervasive use of introspection and exploitation
  of tacit information
• Supported by a reliable, scalable
  planetary-scale Information Utility
• Technical Approach Pervasive Information
  Utility, based on new concept of fluid systems,
  supporting innovative applications for problem
  solving learning

Implementation Deployment of Oceanic Data Info
UtilityLeader Kubiatowicz

• Confederations of (Mutually Suspicious) Utilities

• Infrastructure storage for ubiquitous devices and
  mobile users
• Needed strong security, coherence, automatic
  replica management optimization, simple
  automatic recovery from disasters, utility model
• New Technology expanding search, erasure coding,
  introspective monitoring optimization,
  incremental cryptographic techniques

Sensor-Centric Data Management for
Capture/ReuseLeader Hellerstein

• Managing Data Floods
• Never ends interactive direction
• Big data reduction/aggregation
• Unpredictable scale of devices and nets not
  behave nicely
• Builds on CONTROL and River/Eddy System
• Early answers, interactivity, online aggregation
• Information processing via massively parallel,
  adaptive dataflows
• Extended to wide-area operator placement,
  reordering

• Telegraph Data Manager
• Distributed Storage Manager based on event flow
  and state machines
• Continuously adaptive dataflow with applications
  to sensor data and streaming media

Tacit Knowledge Infrastructureand Collaborative
ApplicationsLeaders Canny/Joseph/Landay

• Exploit information about the flow of information
  to improve collaborative work
• Capture, organize, and place tacit information
  for most effective use
• Learning techniques infer communications flow,
  indirect relationships, availability/participation
  to enhance awareness and support opportunistic
  decision making
• New applications
• 3D activity spaces for representing
  decision-making activities, people, information
  sources
• Visual cues to denote strength of ties between
  agents, awareness levels, activity tracking,
  attention span
• Electronic Problem-based Learning in Enhanced
  Physical and Virtual Learning Spaces
