Visual illusions are fascinating phenomena that have been used and studied by artists and scientists for centuries, leading to important discoveries about how conscious perception is generated by the brain. Instead of crafting them by hand, Pyllusion offers a framework to manipulate and generate illusions in a systematic way. The parametric approach implemented in this software proposes to describe illusions using a set of parameters, such as for instance the difference and illusion strength. These two parameters can be modulated to independently impact either the objective difference of the core components of the illusion (e.g., the difference between the two segments in the Müller-Lyer illusion) or the intensity of the illusion effect (e.g., the angle of the “distractors” arrows). Describing illusions using a set of parameters aims at fostering reproducible science, allowing neuroscientists to easily report, generate and manipulate similar stimuli regardless of the display format and software.
