Crowds and Emergent Teamwork
Crowd modeling began with a focus on group motion. Newer applications in games, movies, training and historical recreations require large groups of characters involved in other kinds of activities. An interesting topic is crowds with a global goal such as foraging, search or construction. These collective behaviors have globally observable results so individual agents must act to achieve those goals. Inspiration for the design of such controllers can be found in the behavior of social insects and other self-organizing natural systems. This talk will review crowd models, collective behaviors in nature, and show some recent simulation results.
Transformed Social Interaction in Virtual Reality
Unlike telephone conversations and videoconferences, avatars - representations of people in virtual environments - have the ability to control their physical appearance and behavioral actions in the eyes of their conversational partners, strategically enhancing or hiding features and nonverbal signals in real-time. This talk explores the manners in which avatars change the nature of remote communication, and how these transformations can impact the ability to influence others in social and professional contexts.

Deciphering interactions that make swarms smart
The amazing abilities of social insects to solve their everyday-life problems, also known as « swarm intelligence », have received a considerable attention these past ten years. Their colonies ranging from a few animals to millions of individuals display fascinating behaviors that combine efficiency with both flexibility and robustness. From the traffic management on a foraging network to the building of efficient nest architectures along with the dynamic task allocation between workers, examples of complex and sophisticated behaviors are numerous and diverse among social insects. The identification and the quantification of interactions taking place among individual insects is a crucial step for building reliable models of these collective behaviors. This talk will explore through several examples the methods and models used to decipher the mechanisms that govern the intelligence of swarms.
