A person's emotions and state of mind are apparent in their face and eyes. As a Latin proverb states: " The face is the portrait of the mind; the eyes, its informers. ". This presents a huge challenge for computer graphics researchers in the generation of artificial entities that aim to replicate the movement and appearance of the human eye, which is so(More)
Most information visualisation methods are based on abstract visual representations without any concrete manifestation in the " real world ". However, a variety of abstract datasets can indeed be related to, and hence enriched by, real-world aspects. In these cases an additional virtual representation of the 3D object can help to gain a better insight into(More)
In this paper, we investigate the ability of humans to determine the gender of conversing characters, based on facial and body cues for emotion. We used a corpus of simultaneously captured facial and body motions from four male and four female actors. In our Gender Rating task, participants were asked to rate how male or female they considered the motions(More)

In this paper, we conducted a perceptual experiment to determine if specific personality traits can be portrayed through eye and head movement in the absence of other facial animation cues. We created a collection of eye and head motions captured from three female actors portraying different personalities, while listening to instructional videos. In a(More)
Communicative behaviors are a very important aspect of human behavior, and deserve special attention when simulating groups and crowds of virtual pedestrians. Previous approaches have tended to focus on generating believable gestures for individual characters and talker-listener behaviors for static groups. In this paper, we consider the problem of creating(More)
In this article, we investigate the perception of gender from the motion of virtual humans under different emotional conditions and explore the effect of emotional bias on gender perception (e.g., anger being attributed to males more than females). As motion types can present different levels of physiological cues, we also explore how two types of motion(More)
The change of glucose, enzymes (GOT, LDH) and metabolites (free fatty acids, urea, lactat) in blood serum of 40 male Simmental calves was investigated during a 48 hours starvation period. During starvation period the concentration of glucose decreased from 3.71 ± 0.06 mmol/I to 2.16 ± 0.05 mmol/l. We observed an increase of GOT-and LDH-activity in blood(More)
