In the past years, the vision science community has benefited a lot from tools such as PsychoPy Python Library to build easily their experiments in the behavioral sciences (neuroscience, psychology, psychophysics, linguistics…). With the advent of virtual reality, we foresee the emergence of new horizons for behavioral sciences. Indeed, with virtual reality, one can potentially build complex, realistic, and more ecological experiments in highly controlled environments. But making such experiments requires a lot of expertise in, e.g., Unity. Our ambition is to provide to the vision science community a new Python Library to conceive experiments in virtual reality without any knowledge on virtual reality.
