“…Sawada et al [2003] found that dancers varied the speed, force, and directness of their arm movements when conveying joy, sadness, and anger. Recent work [Ennis and Egges 2012] investigated the use of complex emotional body language on a virtual character and observed that negative emotions are better recognizable.…”

AngerDisgust Fear Happiness Sadness Surprise AbstractMotion capture remains a popular and widely-used method for animating virtual characters. However, all practical applications of motion capture rely on motion editing techniques to increase the reusability and flexibility of captured motions. Because humans are proficient in detecting and interpreting subtle details in human motion, understanding the perceptual consequences of motion editing is essential. Thus in this work, we perform three experiments to gain a better understanding of how motion editing might affect the emotional content of a captured performance, particularly changes in posture and dynamics, two factors shown to be important perceptual indicators of bodily emotions. In these studies, we analyse the properties (angles and velocities) and perception (recognition rates and perceived intensities) of a varied set of full-body motion clips representing the six emotions anger, disgust, fear, happiness, sadness, and surprise. We have found that emotions are mostly conveyed through the upper body, that the perceived intensity of an emotion can be reduced by blending with a neutral motion, and that posture changes can alter the perceived emotion but subtle changes in dynamics only alter the intensity.

“…In order to ensure that the emotions conveyed by the virtual character are interpreted as intended, a number of studies on the perception of emotion through body motion have been carried out, with conversing virtual characters as the stimuli. We have found that some complex and subtle body motions are difficult to convey through body motion alone, and so have highlighted the importance of the appropriate combination of facial and body motions [EE12]. The literature suggests that the combination of facial and body motions does increase the perception of expressiveness of such emotions on video game characters ( Figure 6).…”

The TARDIS project aims to build a scenario-based serious-game simulation platform for NEETs and job-inclusion associations that supports social training and coaching in the context of job interviews. This paper presents the general architecture of the TARDIS job interview simulator, and the serious game paradigm that we are developing. 1 NEET is a government acronym for young people not in employment, education or training. 2 ec.europa.eu/eurostat 3
