“…Recently, Kim et al (2016) used both 2D screens and HMDs to rate the similarity of simulations to videos of real scenes. Model validation using VR represents an ongoing theme in crowd simulation research, and a recent summary and discussion is provided by Pelechano and Allbecky (2016).…”

Agent-based crowd simulations are used for modelling building and space usage, allowing designers to explore hypothetical real-world scenarios, including extraordinary events such as evacuations. Existing work which engages virtual reality (VR) as a platform for crowd simulations has been primarily focussed on the validation of simulation models through observation; the use of interactions such as gaze to enhance a sense of immersion; or studies of proxemics. In this work, we extend previous studies of proxemics and examine the effects of varying crowd density on user experience and behaviour. We have created a simulation in which participants walk freely and perform a routine manual task, whilst interacting with agents controlled by a typical social force simulation model. We examine and report the effects of crowd density on both affective state and behaviour. Our results show a significant increase in negative affect with density, measured using a self-report scale. We further show significant differences in some aspects of user behaviours, using video analysis, and discuss how our results relate to VR simulation design for mixed human-agent scenarios.

“…Interestingly, they showed that crowds of real human subjects exhibit typical patterns of real crowds, as observed in crowded real-life situations. In addition, some researchers propose papers that evaluate and measure the impact of user's presence, such as [51,80,108]. For instance, in [54], authors propose to investigate performance and user experience in Social Virtual Reality (SVR) embodied, immersive, and providing face-to-face encounters.…”

“…Therefore there is a need to perform such perceptual evaluations from a first person point of view. Immersive Virtual Environments offer a platform to study human behavior as long as the participant experiences high levels of presence which will lead to real responses to the virtual characters [30], [27], [20].…”

Understanding human decision making is a key requirement to improve crowd simulation models so that they can better mimic real human behaviour. It is often difficult to study human decision making during dangerous situations because of the complexity of the scenarios and situations to be simulated. Immersive virtual reality offers the possibility to carry out such experiments without exposing participants to real danger. In the real world it has often been observed that people tend to follow others in certain situations (e.g: unfamiliar environments or stressful situations). In this paper we study human following behaviour when it comes to exit choice during an evacuation of a train station. We have carried out immersive VR experiments under different levels of stress (alarm only or alarm plus fire) and we have observed how humans consistently tend to follow the crowd regardless of the levels of stress. Our results show that decision making is strongly influenced by the behavior of the virtual crowd: the more virtual people running the more likely are participants to simply follow others. The results of this work could improve behavior simulation models during crowd evacuation, and thus build more plausible scenarios for training firefighters.
