Evaluating Emotive Character Animations Created with Procedural Animation

چکیده
How to create effective body animations for virtual agents with emotions remains the state of the art for human animators and a great challenge for computer scientists. In this paper, we propose to use a model of hierarchal parameters to represent body animations: emotional, style, motion, and procedural parameters. Based on this model, we have created motions for a virtual character with generic animation procedures and mapped these procedural parameters into style parameters as proposed in the literature. The expressiveness of the generated animations was verified through experiments in our previous work. In this paper, we further report the results of two experiments attempting to verify how the style parameters are mapped into various emotions. The results reveal that the participants can successfully distinguish emotions based on the manipulation of style parameters for neutral motions such as walking. When these style parameters were used for emotive motions, including pounding, shivering, flourishing and crestfallen, the generated animations were even more effective for intended contexts.

Parameter Spaces, Spacetime Control and Motion Graphs for Automating the Animation of Videogame Characters
Character animations are a crucial part of many interactive applications, from training simulations to videogames. As these applications have become more sophisticated, the growing number of character animations required has made standard animation techniques like key-framing and motion-capture increasingly expensive and time-consuming. Procedurally generating animations appears to offer a solu...

In this paper, we propose to use procedural animation of a human character to enhance the interpretation of music. The system consists of a procedural motion generator which generates expressive motions according to music features extracted from a music input, and uses Dynamic Programming (DP) to segment a piece of music into several music segments for further planning of character animations. ...

Physical realism plays an important role in the way character animations are being perceived. We present a method for evaluating the physical realism of character animations, by using musculoskeletal model simulation resulting from biomechanics research. We describe how such models can be used without the presence of external force measurements. We define two quality measures that describe prin...

Procedural animation [1][3] has the advantage of being able to generate flexible animations according to high-level parameters while motion capture-based (MoCap-based) methods [2] have the advantage of creating realistic animations. In this paper, we attempt to use the data from motion capture to automatically find an optimal set of parameters that can be used to produce realistic animations fo...
