A web application was implemented on Glitch with JavaScript + HTML. On the top page, participants are presented with examples of generated and real images, as well as an explanation of the VTT methodology (panel A). Once the test starts, participants are presented with the polar maps one by one and prompted to answer whether the image is real or fake, as shown in Panel B. Each time one of the buttons is clicked, the presented image is randomly selected from a database containing a mixture of original and generated images. After a total of 10 questions, the CAR is calculated and displayed as shown in Panel C.

CAR: correct answer rate
