- In order to explain and model emotion we need to attend to the role internal states play in the generation of behavior. We argue that motivational and perceptual roles emerge from the dynamical interaction between physiological processes, sensory-motor processes and the environment. We investigate two aspects inherent to emotion appraisal and response which rely on physiological process: the ability to categorize relations with the environment and to modulate response generating different action tendencies.

- In this paper we describe a system allowing users to express themselves through their full-body movement and gesture and to control in real-time the generation of an audio-visual feedback. The systems analyses in real-time the user’s full-body movement and gesture, extracts expressive motion features and maps the values of the expressive motion features onto real-time control of acoustic parameters for rendering a music performance. At the same time, a visual feedback generated in real-time is projected on a screen in front of the users with their coloured silhouette, depending on the emotion their movement communicates. Human movement analysis and visual feedback generation were done with the EyesWeb software platform and the music performance rendering with pDM. Evaluation tests were done with human participants to test the usability of the interface and the effectiveness of the design.

- Different design approaches contributed to what we see today as the prevalent design paradigm for Human Computer Interaction; though they have been mostly applied to the visual aspect of interaction. In this paper we presented a proposal for sound design strategies that can be used in applications involving affective interaction. For testing our approach we propose the sonification of the Affective Diary, a digital diary with focus on emotions, affects, and bodily experience of the user. We applied results from studies in music and emotion to sonic interaction design. This is one of the first attempts introducing different physics-based models for the real-time complete sonification of an interactive user interface in portable devices.

Konferensbidrag (refereegranskat)abstract
- It has been shown that users of a digital system perceive a more ‘masculine-sounding’ female voice as more persuasive and intelligent than a corresponding but more ‘feminine-sounding’ female voice. Our study explores whether a parallel pattern of affectively colored evaluations can be elicited when femininity and masculinity are manipulated via visual cues instead of via voice. 80 participants encountered synthetic characters, visually manipulated in terms of femininity and masculinity but with voice, spoken content, linguistic style and role of characters held constant. Evaluations of the two female characters differed in accordance with stereotype predictions – with the exception of competence-related traits; for the two male characters evaluations differed very little. The pattern for male versus female characters was slightly in opposite to stereotype predictions. Possible explanations for these results are proposed. In conclusion we discuss the value of being aware of how different traits in synthetic characters may interact.
