Affective rendering: Visual effect animations for affecting user arousal

We propose affective rendering as a new affective computing technology which deals with user emotion in the field of image synthesis. Affective rendering is realized in 3 steps - affect sensing, affect analysis and affect adapted rendering. This paper reports several basic experiments carried out for studying how the typical visual parameters, such as color and shape, affect view´s arousal, and also describes a prototyping of visual effect animations that can affect viewer´s arousal by adapting the visual parameters to user´s current arousal estimated from respiration and blood volume.
