Description: Human audiovisual thresholds can be difficult to measure due to the requirement of high-precision synchronization between the audio and visual components of the stimulus. A major accomplishment of this project was the design of a platform for conducting audiovisual experiments that was both portable between different hardware systems and robust to synchronization issues. Our design was validated by conducting experiments on measuring audiovisual synchrony thresholds. Our results show that the audio lag threshold is larger than the video lag threshold, as has been found in other studies. We extended our experiment to study the effect of prior knowledge of a stimulus on threshold. Specifically, we removed the expectation of the asynchrony direction, and found that threshold did not change significantly. Ultimately, our results provide a more complete understanding of how audiovisual synchrony is perceived by human observers.
