Affective smile and interaction

Abstract

It is well known that laughing is good for the health. However, there are many parts that have not been clarified about the manner of laughter. In this paper, we discuss the relationship between facial expressions and affective smile. The face to be handled here uses a line drawing expressed by an illustration. The lines of “eyes” and “mouth” for drawing an affective smile use a logarithmic spiral obtained from the golden ratio. Here we show the relationship between laughter and happiness. People can feel happiness by applying the fact that the brain feels happiness and being deceived by laughing, smiling. The central idea in this paper is that affective smile gives people a feeling of happiness. Also it is shown the hypothesis that affective smile exists in three overlapping intersections “fun”, “interesting” and “comfortable”. As a result, the following hypothesis is also shown that affective smile is a function of interaction.
