Proem

• http//wearables.cs.uoregon.edu/proem
• A P2P platform for mobile ad-hoc networks
• Four entity types peer (device), individual
  (user), data space, community (a set of entities)
• Four protocols transport (XML messages),
  presence, data, community
• Application environment runtime (peerlets
  peerlet engines), peerlet development kits

one.world

• http//one.cs.washington.edu
• A system architecture for pervasive computing
• Provides an integrated and comprehensive
  framework for building pervasive applications
• Includes a set of services, such as service
  discovery, checkpointing, and migration that help
  to structure applications and cope with constant
  change
• one.world slides and sample code

Testing Electronic Guidebook

• 35 users 16 adult females, 9 adult males, 8
  children (aged 10 to 13)
• Some users in small groups sharing a PDA
• Testing under normal Exploratriums condition
• Brief introduction, then directed to 6
  instrumented exhibits
• A project member observed the users actions,
  held semistructured interviews afterwards
