... feature

In [4], emotion perception is a two-step process of probabilistic nature in which expressive features correspond to separate configurations of the upper and the lower part of the face. Due to technical constraints detailed in Section 3, we didn't integrate enough expressive features in Feelix face to be able to implement this probabilistic model. We therefore decided to take the most expressive feature of each part of the face.

... raised

When we talk about raised or lowered eyebrows, it is in fact their external ends that are raised or lowered, since the internal end of each eyebrow is attached to a shaft and therefore eyebrows can only rotate on that axis.

... duration

Affective states with a long duration are called moods. They are much less intense and have different elicitors and much weaker associated (behavioral, physiological, etc.) manifestations; they make more likely the onset of specific emotions. Emotional states with an intensity below the activation threshold can be seen as moods in Feelix.

... expressions

These figures exclude results for fear in the robot tests and for contempt in the human faces one, since all subjects agreed that these expressions very bad (results were close to 0%). Their inclusion lowers figures by about 10 points.
