ingimp is a version of the GNU Image Manipulation Program that has been instrumented to collect real-time usability data. It is not a plug-in but a complete, standalone version of the GIMP. All usability data is automatically transmitted to this website for anyone to download and analyze. We also provide our own analyses (see below). ingimp is part of human-computer interaction (HCI) research at the University of Waterloo investigating new forms of sustainable open usability.
