What is "phidget"

A phidget is a physical representation or implementation of a GUI widget. For example, an on-screen dial widget could be implemented physically as a knob.

Phidgets are a system of low-cost electronic components and sensors that are controlled by a personal computer. Using the Universal Serial Bus (USB) as the basis for all phidgets, the complexity is managed behind an Application Programming Interface (API). Applications can be developed in Mac OS X, Linux, Windows CE and Windows operating systems.

Their usage is primarily focused to allow exploration of alternative physical computer interaction systems, but have most notably been adopted by robotic enthusiasts as they greatly simplify PC-Robot interaction. Phidgets are an attempt to build physical analogue to software widgets, allowing the construction of complex physical systems out of simpler components. Phidgets are designed and produced by Phidgets Inc.
