共創システムとは人間のコミュニケーションをその内側から捉えるシステムである.本稿では,主観的時間としての「間( ま)」に注目し,その生成とインターパーソナルな共有の仕組みについて紹介する.具体的には,協調タッピング課題を用いたリズム運動の相互引き込みのモデル化を踏まえ,人間と人工物のインタラクション,特に歩行リズムのリハビリテーション支援への有効性を示す.これはリズム運動とその同調を人間の内側から支援する新しいシステム論に向けての第一歩である.

我々は,ショウジョウバエの頭尾軸形成における遺伝子発現の理論的研究を通じて,多細胞生物における細胞の観測行為と観測結果の関係を数理的にモデル化し,個体差に対する遺伝子の発現パターンのロバスト性に対して新たな説明を与えた.この数理モデルは,発生生物学の問題に限らず,広く生物システムにおける主体の行為と知覚,およびそれに基づく認識のロバスト性に関する現象をモデル化する際に数理的観点から示唆を与えるものと考えられる.そこで,本稿では,ショウジョウバエの頭尾軸形成における遺伝子発現におけるロバスト性の問題を例にして,この数理モデルの特徴について解説を行う.

In radiotherapy, it is essential to focus the radiation on the affected parts of the internal organs, like lung, liveretc., while minimizing the exposure to healthy tissues. Although methods that apply the beam to affected parts in synchronization with the patients' breathing have been used extensively, irradiation accuracy is not sufficient when the respiratory status of the patient is unstable. In this paper, we propose a new irradiation system that features (1) stabilizing the patients' respiration by synchronizing the rhythm of his/her breathing with that of music being played, and (2) controlling the timing of the irradiation based on the predicted respiratory phase instead of the measured phase that has been used widely. From experimental results using 12 subjects, it is possible to clarify that deviation of the beam irradiation position from the targeted point has been decreased to one-third as compared to conventionalmethods, resulting in a dramatic improvement in the accuracy of the irradiation system.

In this research, we analyzed the dialogue that consisted of an instruction and a response utterance to clarify the relation between cognitive process and timing structure of utterance. The results showed that correlation coefficient between duration of instruction utterance and switching pause had diverse values when fluctuation of instruction utterance duration was too small to be recognized. However, the correlation coefficient between them had positive and high value when fluctuation of instruction utterance was explicitly big. From these results, we discussed that there are two types of utterance structure in human dialogue.

The purpose of this study is to clarify the effects of timing control of utterance and body motion in human-robot interaction. Our previous study has already revealed the correlation of timing of utterance and body motion in human-human communication. Here we proposed a timing control model based on our previous research and estimated its influence to realize human-like communication using a questionnaire method. The results showed that the difference of effectiveness between the communication with the timing control model and that without it was observed. In addition, elderly people evaluated the communication with timing control much higher than younger people. These results show not only the importance of timing control of utterance and body motion in human communication but also its effectiveness for realizing human-like human-robot interaction.

The purpose of this study is to clarify the influence from timing of utterance and body motion in dialogue between human and robot. We controlled pause duration and nod response timing in robot-side, and analyzed impression of communication in human-side by using Scheffe's Paired Comparison method. The results revealed that the impression of communication significantly modified by changing the pause duration and nod response timing. And, timing pattern of the impression altered diversely in elderly people than in younger, indicating that elderly generation uses various timing control mechanisms. From these results, it was suggested that timing control and impression of communication are mutually influenced, and this mechanism is thought to be useful to realize human-robot communication system for elderly generation.
