We explored the potential of audiovisual semiotics, the use of audiovisual channels, to enhance users' intuitive perception of uncertainty by conducting two user studies. In the first experiment we assessed the intuitiveness of audio/visual pairs. In the second experiment, we investigated the intuitive audiovisual mappings of uncertainty.

These supplemental materials contain the files for the experimental setup of the two user studies, experimental stimuli used in both experiments, the data collected from the two experiments and r scripts for analysis.
