ARCrowd-a tangible interface for interactive crowd simulation

Manipulating a large virtual crowd in an interactive virtual reality environment is a challenging task due to the limitations of the traditional user interface. To address this problem, a tangible interface based on augmented reality (AR) is introduced. Through the tangible AR interface, the user could manipulate the virtual characters directly, or control the crowd behaviors with markers. These markers are used to adjust the environment factors, the decision-making processes of virtual crowds, and their reactions. The AR interface provides more intuitive means of control for the users, promoting the efficiency of human-machine interface.
