An embodied entrainment character cell phone by speech and head motion inputs

The head movements and actions have an important role of the intentional expression of the affirmative and the denial in communications as well as the regulation of conversation. In this paper, we develop a speech-input-driven embodied interaction cell phone with a Narikiri-headset which reflects the user´s head movements and actions directly in Inter-Actor by an acceleration sensor and a gyro sensor. Therefore, humans can use this system to communicate effectively by using deliberate body movements as well as natural communicative movements and actions in a mobile environment. In addition, the effectiveness of the system is demonstrated by a sensory evaluation experiment.
