Virtual audiences have been found to be useful tools in the treatment of public speaking anxiety, and recent results also show they could be used for training public speaking skills for non-anxious individuals. However, relatively little research has investigated how virtual audiences are perceived. Understanding how virtual audiences are perceived depending on their non-verbal behavior is crucial to create relevant, controllable stimuli. In this paper, we present our virtual audience behavior

We used this model to create a collection of virtual audience videos where different states, such as boredom or engagement, are expressed through varying behaviors, such as postures, gazes, or facial expressions. We used this dataset to investigate the perception of virtual audiences, and present our results according to three perspectives of analysis: the recognition of overall audience states, the influence of behavioral parameters on virtual audience perception, and the recognition of individual audience members' states.
