Phidgets def. A phidget is a physical representation and/or implementation of a GUI widget.Check out this YouTube video of a raise hand phidget created by Yunatio Li (yuntao2006 at gmail with a dot com), a graduate student at the University of Carleton. Yunatio's supervisor is professor Michael Weiss.
This video demonstrates how an instructor could be notified, by a physical device, when a remote student raises their hand during a presentation in BigBlueButton. Here's another video that demonstrates logging into BigBlueButton using a smart card reader.Very cool!
