“…Including personality traits can further enhance the plausibility of a virtual crowd. The OCEAN personality model [27] has been used in different crowd simulation models (such as HiDAC [6], RVO [9], and Biocrowds [10]) to provide each virtual agent in a crowd with personality traits. These models successfully modify the decision making or local movement parameters, thus resulting in a more heterogeneous crowd simulation, although agents are still limited to showing exclusively locomotion animations.…”

Simulating virtual crowds is an important challenge in many areas such as games and virtual reality applications. A lot of effort has been dedicated to improving pathfinding, collision avoidance, or decision making, to achieve more realistic human-like behavior. However, crowd simulation will be far from appearing realistic as long as virtual humans are limited to walking animations. Including animation variety could greatly enhance the plausibility of the populated environment. In this paper, we evaluated to what extend animation variety can affect the perceived level of realism of a crowd, regardless of the appearance of the virtual agents (bots vs. humanoids). The goal of this study is to provide recommendations for crowd animation and rendering when simulating crowds. Our results show that the perceived realism of the crowd trajectories and animations is significantly higher when using a variety of animations as opposed to simply having locomotion animations, but only if we render realistic humanoids. If we can only render agents as bots, then there is no much gain from having animation variety, in fact, it could potentially lower the perceived quality of the trajectories.

“…There are crowd simulation models that incorporate personality and psychological state to affect human movement, but it is typically limited to modifying speeds, queuing behavior, or personal space [13,17,28]. It is thus necessary to better understand how elements such as stress or nervousness can affect human decision making to be able to closely simulate it.…”

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.

“…Following the previous definition, we defined the influence that such traits have on the behavior of our agents, during the FFA method. To do so, we follow the method proposed by Knob et al [11] to create a relationship between OCEAN traits and behaviors, as following defined:…”

“…There are methods that deal with crowds from a microscopic point of view [2], [3], as well methods that deal with a macroscopic point of view [4], [5] and, even, methods which combine both microscopic and macroscopic simulation strategies [6]. Others explored high dense crowds [2], [7], heterogeneous behaviors [8], navigation control [9] and personality traits for agents [10], [11].…”

This article proposes an adaptation from the model of Bianco for fast-forwarding agents in crowd simulation, which enables us to accurately fast forward agents in time. Besides being able to jump from one position to another, agents are able to stay inside their track, it means, the new position is calculated taking into account the original global path the agent would follow, if not being fast-forwarded. Obstacles and other agents around are also taken into account when calculating the new position. In addition, we included a personality aspect on agents, which affect their behaviors and, also, be taken into account when jumping to a future time and space. We conducted some experiments to validate our model, which shows that it was able to indeed fast forward agents from a position to another, in a coherent time, sticking to a given global path while avoiding collisions. Finally, we present a use case, showing that our method can fit inside a "Fog of War" system.
