CommonSense ToolKit

CSTK: open source tools for sensor communication, sensor data processing and visualization. Doesn't seem to have been updated much since 2004-2006, but Dr. Kristof Van Laerhoven appears to be the current manager of the code. Several papers describe its design intention, features, and examples. I've downloaded it and will see if I can get it running. One criticism of this toolbox is that it is missing support for sending commands to a node and receiving more complex data types from a sensor. Perhaps these can be added to the code base?
