ElPrimo is a script language which can use to modelize image-based experiments. The idea came from E-Prime, a powerful suite of applications to make computerized experiments.
By ElPrimo, a set of images can be proposed in an interactive manner and the reactions on the keyboard can be recorded for the subseguent analizing process.
ElPrimo scripts can be executed by a Java program, available as jarfile, in the download area.
