Golaem is a France-based software developer of solutions dedicated to the population of 3D environments using autonomous human-like characters. Golaem was created in 2009 by researchers and engineers from INRIA, a major French research center, leveraging on 15 years of research on the modeling and simulation of human characters. Wikipedia.

Reconstruction is a key step of the motion capture process. The quality of motion data first results from the quality of raw data. However, it also depends on the motion reconstruction step, especially when raw data suffer markers losses or noise due, for example, to challenging conditions of capture. Labeling is a final and crucial data reconstruction step that enables practical use of motion data (e.g., analysis). The lower the data quality, the more time consuming and tedious the labeling step, because human intervention cannot be avoided: he has to manually indicate markers label each time a loss of the marker in time occurs. In the context of crowd study, we faced such situation when we performed experiments on the locomotion of groups of people. Data reconstruction poses several problems such as markers labeling, interpolation and mean position computation. While Vicon IQ software has difficulties to automatically label markers for the crowd experiment we carried out, we propose a specific method to label our data and estimate participants mean positions with incomplete data. © 2011 Springer-Verlag.

While walking through a crowd, a pedestrian experiences a large number of interactions with his neighbors. The nature of these interactions is varied, and it has been observed that macroscopic phenomena emerge from the combination of these local interactions. Crowd models have hitherto considered collision avoidance as the unique type of interactions between individuals, few have considered walking in groups. By contrast, our paper focuses on interactions due to the following behaviors of pedestrians. Following is frequently observed when people walk in corridors or when they queue. Typical macroscopic stop-and-go waves emerge under such traffic conditions. Our contributions are, first, an experimental study on following behaviors, second, a numerical model for simulating such interactions, and third, its calibration, evaluation and applications. Through an experimental approach, we elaborate and calibrate a model from microscopic analysis of real kinematics data collected during experiments. We carefully evaluate our model both at the microscopic and the macroscopic levels. We also demonstrate our approach on applications where following interactions are prominent. © 2012 The Author(s).

We use the results of a pedestrian tracking experiment to identify a follow-the-leader model for pedestrians walking-in-line. We demonstrate the existence of a time-delay between a subject's response and the predecessor's corresponding behavior. This time-delay induces an instability which can be damped out by a suitable relaxation. By comparisons with the experimental data, we show that the model reproduces well the emergence of large-scale structures such as congestions waves. The resulting model can be used either for modeling pedestrian queuing behavior or can be incorporated into bi-dimensional models of pedestrian traffic. © American Institute of Mathematical Sciences.

POPULATE, which is the acronym for POPULate AsymmeTric mobile gamEs, is an Innovation Action in the field of mobile games. The proposal focuses on innovation, by combining a multi-devices approach to game design with a state of the art crowd simulation technology, and so favor a game with a simple gameplay. The objective is to develop a prototype involving crowds for asymmetric games using both wearable and mobile devices as controllers and using TV as the main display. In the proposed gameplay, the player will have to defend himself, armed only with giant balls propulsed then controlled through natural motions, against ravenous hordes of digital creatures. Other players will have the ability to influence the appearance and behavior of the horde against the defender. AMA Romania, top developing and R&D studio of AMA world leader of innovative interactive entertainment software on all devices, needs to carry further its innovative expertise on its game by exploring the possibilities of multi-devices interaction to offer gamers a premium experience. Connected objects, such as glasses or watches, are the new gaming frontier, naturally immersing players and offering exciting new ways of interacting with the digital world. Golaem is developing Golaem for Games, an add-on to Golaem Crowd to be integrated in game engines by game studios, to interactively replay crowd simulations configured by artists. For this development to be successful Golaem needs to team up with a game studio to validate the needs and usefulness of the product. The added value Golaem will provide to the project is in the gain of production time to generate a visually diverse crowd of autonomous characters. The Graphics, Vision and Visualisation Group of the Trinity College of Dublin will study the influence of the appearance, behaviors and animation realism of creatures on the defender. Is the cuteness of the creatures an element which can be used in gameplay design to stress the player?
