• New themes will drive next 5-10 years of wireless
  sensing systems
• Mobile, Multi-scale, Multi-modal
• Integrity, sensing, participatory and
  interactive
• Publishing and sharing sensor data
• New integrated-sensor development will take time
  and investment..Therefore, leverage existing
  sensors in creative ways (imagers, acoustics, )
• Participatory sensing public health, social,
  personal
• Technology development model
• Early-to-application to leverage deployments
  and resulting data provides feedback to system
  innovation, from theory to algorithm

Coupled Human-Observational Systems

• Whereas we focused initially on very long lived,
  autonomous systems design, interactive and rapid
  deployments are high value.
• Interactive systems take advantage of human
  observer, actuator
• Addresses critical issues such as adaptive
  sampling, topology adjustment and faulty sensor
  detection
• Requires real time data access, model based
  analysis, and visualization in the field

Handheld Sensing

• From data entry to imagers to connected sensors
  (bluetooth, usb)
• Automatic geocoding
• Automatic upload
• Real-time sanity-checking of data on handheld or
  on server end
• Access to maps, models, reference images or data

11
Participatory Sensing From Eco-Systems to Human
Systems

• Enabled by
• Over 2x109 users worldwide of cell phones.
• Automated geo-coding and pervasive connectivity
• Image and acoustic as data and metadata
• Local processing for data quality and triggering
• Spatial interface to data and authoring

• Applications
• Self-administered health diagnostics
• Public health/epidemiology Water and Air
• Civic concerns (transportation, safety)
• Eco-PDA

Science application drivers

• Early embedded sensing applications
• Biological and Earth Sciences
• Environmental, Civil, Bio Engineering
• Public health, Medical research
• Agriculture, Resource management

• Science is our early adopter for networked
  sensing because the technology is transformative
  and research tolerates risk
• The maturing technology will also transform the
  business enterprise
• Important historical precedents
• Weather modeling--early computing
• Scientific collaboration--Internet
• Experimental physics (CERN)--WWW
• Computational science--Grid computing

• Embeddable device developments
• Energy-conserving platforms, radios
• Actuated/Mobile platforms
• Standardized software interfaces
• Signal/image processing techniques
