Creating realistic crowd behavior is one of the major goals in crowd simulations. Simulating gaze behavior and predicting interest points of virtual characters play a signifficant role in creating believable scenes, however this aspect has not received much attention in the field. This study proposes a saliency model, which enables virtual agents to produce gaze behavior. The model measures the effects of distinct pre-deffined saliency features that are implemented by examining the state-of-the-art perception studies. When predicting an agent's interest point, we compute the saliency scores by using a weighted sum function for other agents and environment objects in the field of view of the agent for each frame. Then we determine the most salient entity in the virtual scene according to the viewer agent by comparing the scores. We execute this process for each agent in the scene, thus agents gain a visual understanding about their environment. Besides, our model introduces new aspects to crowd perception, such as perceiving characters as groups of people, gaze copy phenomena and effects of agent velocity on attention. For evaluation, we compare the resulting saliency gaze model with real world crowd behavior in captured videos. In the experiments, we simulate the gaze behavior in real crowds. The results show that the proposed approach generates plausible gaze behaviors and is easily adaptable to varying scenarios for virtual crowds.
