RUI: recording user input from interfaces under Windows and Mac OS X

Event and timing logs are useful i n studying human-computer interaction,evaluating applications, and comparing input devices. Recording User Input (RUI) is a tool that records user-computer interface behavior. It is created in the .Net framework with C# for Windows and in the Carbon framework for Mac OS X. RUI runs in the background and works with software that runs under Windows or Mac OS X (10.3 Panther and later versions). We illustrate its use with a human-robot interaction interface and present two simple tests that RUI passes and that other timing software should pass: avoiding 0-msec timings and time distributions that follow a gamma (or gamma-like) distribution.
