A study of emotional motion description by motion modification rules using adjectival expressions

Emotion expression through behavior is meaningful for communication processes between robots and humans. Automatic emotion expression generation is needed for those robots in order to stimulate communication with humans. Proposed technique generates emotional motions by modifying base motion patterns using the combination of the adjectival expressions. In order to generate emotional motions, emotional motion modifications should be based on rules which represent the relationship between emotion expressions and the combination of the adjectival expressions. Emotion modification rules are obtained by organoleptic tests. This paper, in particular, shows the relationship between the degree of adjectival modification and emotion expressions. Thus proposed technique generates the suitable emotional motion patterns from base motion pattern.
