The strong demand for an easy light control system using gesture is observed. Especially the system that can deal with multicolor illumination will be favored. However, there are very few studies considering light color control with gesture as the input. Connecting light colors and gestures is a tough task. Therefore, in this research, we evaluated the relationship among light color, gesture and emotion, and proposed a method to connect light color and gesture via emotion. Furthermore, we investigated light color control by gesture using this proposed method. First, the relationship between light color and emotion was expressed by Russell’s circumplex model. This model is a representation of all emotions with two independent axes. Next, gestures were comprehensively extracted, and three types of gestures were selected based on Laban theory, emotional expression and sign language. Using three kinds of selected motions, we implemented the experiments of light color control and compared and evaluated. As a result of evaluating in terms of the qualitative viewpoint (questionnaire evaluation) and the quantitative viewpoint (NEM), it was shown that the gesture of emotional expression is the most emotional gesture in light color control and the possibility to perform light color control using gesture. From the results of this research, we showed that the gesture based on emotional expression is the most suitable gesture in light color control. Further studies on more intuitive gestures are needed.
