CAT

CAT Context Aware Toolkit

• A framework for building context-aware
  applications on mobile devices, such as the iPAQ.
  
• Features
• Provides access to all local sensor data.
• Create SIGs (Special Interest Groups) for sharing
  sensor data with only the people you want to.
• Keeps a history of all sensor data.
• Predict future sensor data.
• Facilitates P2P communication.

CAT Context Aware Toolkit

• CAT makes building context-aware applications as
  easy as extending an abstract class.
• Several applications have been built using CAT,
  including ActiveCampus and Navigator.
• Testing CAT and other mobile applications can be
  very difficult due to limited time and resources.

iSIM iPAQ SIMulator

• iSIM can simulate sensor context and wireless
  networking for multiple agents.
• Each agent in the iSIM environment corresponds to
  some mobile application like CAT.
• CAT can then receive context from iSIM, just like
  it would from a real mobile device.

iSIM iPAQ SIMulator

• iSIM Scenario
• Add a couple of agents to iSIM.
• Add an access point.
• Move the agents and access point.
• Show the wireless ranges.
• ActiveCampus Scenario
• View agents and make a friend.
• View the friends location on the map.
• Talk with the friend.
