Emotion, moods and virtual environments

EMOTIONS, MOODS AND VIRTUAL ENVIRONMENTS

The area of affective computing is attracting increasing attention, covering the ways in which interfaces adapt to the affective states of the users or exhibit affective states themselves. In this vast research domain, HTLab is working at the definition of several behavioural and cognitive indexes of emotional states and activation. A part of this work was done inside the founded EMMA Project. Other studies are shortly presented in this page.

BEHAVIOURAL CORRELATES TO EMOTIONS IN VIRTUAL ENVIRONMENTS
[2003-2004]

We investigated behavioural correlates to emotions, corroborating physiological previous finding. The use of Human Interface Events permit a detailed quantitative description of any human activity during the immersion in a virtual environment, including the respons to emotional stimula (in this experiement we used the Lang Pictures Inventary.

POSTURAL CHANGE AND ACTIVATION IN EMOTIONAL VIRTUAL ENVIRONMENTS

[Partly connected to our involvement in EMMA Project]

The goal of this study was an exploration of the circumstances under which a postural change of the immersed users occurred during the navigation in an EMMA virtual environment. Since those environments were meant to influence the users’ mood, the study focussed on those postural changes that were oriented towards a higher or lower activation. The analysis showd a very close connection between the posture of the whole body and the kind of activity in which the participants are involved in the virtual environment.
