PSYCHOGEAR, YET ANOTHER PSYCHOPHYSICS LIBRARY

This paper presents PsychoGear, a new library of psychophysics methods, which can sup-plements haptic, visual, and audio stimuli. We have developed a modular framework thatarises from the decomposition of an experiment in a series of psychophysics methods,each one composed of a variable number of trials. Constant stimuli, staircases, QUEST,PEST, and Maximum Likelihood adaptive procedures for psychophysics measurement arenatively implemented in our library. Implementation details such as trial presentation,stopping rules, generation of the next stimulus, and data collection are natively handledby the framework. By this way the user (researcher or student) can be concentrated on thedesign of the experiment. Our library is very easy to use with simple and ecient C++code, or with a dedicated GUI to create a XML conguration le of the entire experiment.
