ABSTRACT: From record-setting crowds at rallies and protests to futuristic swarms of robots, our world is currently experiencing a continuing rise of complex, distributed collections of independently acting entities. With potential applications such as computer graphics, predicting crowd disasters, improving robot cooperation, and enabling the next generation of air travel, developing models to reproduce, control, predict and understand these types of systems is becoming critically important.
In this talk, I will give an overview of how to use velocity-space planning techniques to compute cooperative motion paths for a group of
independent entities sharing the same physical space. I will focus
on the special case of simulating human-like crowds, with applications to computer animation and architectural analysis. Specific topics will include optimization-based strategies for distributed collision avoidance, uses of the principle of least effort for simulating crowds, and data-driven strategies for modeling differences in personalities. The talk will also cover related techniques needed to achieve accurate simulations of large-scale crowds such as efficient parallel/SIMD compute models and methods of validating simulations against real world data and will discuss how velocity-space motion planning can be applied to collision avoidance for distributed robotic systems.
