Eros Quarta, Erez James Cohen, Riccardo Bravi, Diego Minciacchi
2020 Frontiers in Systems Neuroscience  
Efforts to understand the neural processes subserving such movements may teach us about general principles of behavior, similarly to how studies on neurological patients have guided early work in cognitive  ...  While investigations on non-human animal models offer valuable information on the neural dynamics of skilled motor control that is still difficult to obtain from humans, sport sciences have paid relatively  ...  It may thus seem intuitive to consider animal modeling of, e.g., running to be less complex than, say, tennis and that differential insights on the cognitive bases of sport performance may be extracted  ...

Simulation theory and anticipation for interactive virtual character in an uncertain world

Cédric Buche, Anne Jeannin-Girardon, Pierre De Loor
2011 Computer Animation and Virtual Worlds  
The underlying idea is to take into account principles from cognitive science, in particular, the human ability to anticipate and simulate the world behavior.  ...  Thanks to this model it is possible to add a human user to launch balls that the virtual juggler can catch whilst juggling.  ...  At the opposite, some models developed in robotics are interaction oriented and rely on cognitive science, but the problem of animation realism is not addressed [3] .  ...

Invoking Behavioral Patterns on Autonomous Virtual Agents by Fuzzy Cognitive Maps and Video Games Techniques using Modern Tools

J. Carlos Conde R., Abraham Sánchez L., Abraham Sánchez F.
2014 Research in Computing Science  
This behavioral system is based on MoCAMG cognitive architecture following a methodology that combines common video-game techniques with non classical methods of AI.  ...  Our work shows the main phases where an appropriate cognitive modeling leads to suitable responses from external stimuli and internal desires.  ...  This is based on the hierarchy of behavioral animation modeling since it has made impressive strides toward autonomy resulting in virtual characters auto-animated endowed of more realistic behaviors [  ...

From motion capture to action capture

Bernhard Jung, Heni Ben Amor, Guido Heumer, Matthias Weber
2006 Proceedings of the ACM symposium on Virtual reality software and technology - VRST '06  
We present a novel method for virtual character animation that we call action capture.  ...  The paper reviews the relevant literature in these areas before framing the concept of action capture in the context of VR-based character animation.  ...  based on spacetime constraints [28] , this process still requires an explicit modeling effort by the human animator [9] .  ...

Lucio Ieronutti, Luca Chittaro
2007 Computers & Education  
Moreover, the programming effort to develop and re-use the virtual human into different learning environments can be considerable.  ...  Virtual humans are more and more used in multimedia learning environments, e.g. to explain maintenance operations, to train medical staff, or can be employed as virtual teachers.  ...  The cognitive modeling instead binds various stimuli with reasoning process that allow the virtual human to search for the most suitable reaction; cognitive models go beyond behavioral models in that they  ...
