This paper describes the properties of proprioceptive sensations induced by an asymmetric vibration using a vibration speaker-type non-grounded haptic interface. We confirm that the vibration speaker generates a perceived force that pulls or pushes a user's hand in a particular direction when an asymmetric amplitude sound signal that is generated by inverting a part of a sine wave is input. We conducted 5 psychophysical experiments and evaluated the subjects' physical properties in order to apply this phenomenon for a variety of applications. As a result, we confirmed that the vibration speaker was able to control both the direction and magnitude of the reaction force by changing the input signal.

When presented with asymmetric vibrations, humans typically experience an illusory force that is similar to the sensation of being pulled toward a particular direction. The pulling illusion has been used in new display elements for a pedestrian navigation system and a VR content because the asymmetric vibrations can be implemented in a small non-grounded device. This paper reviews the findings of the pulling illusion with covering a wide range of topics, including the basic concept, physiological mechanism, optimal parameters for the illusion, the control method of force vectors, the evaluation method of the illusion, and applications. As a result of the review, the research trend of the pulling illusion was confirmed, and the vital points which were stimulation method and parameters of asymmetric vibration to design a haptic interface using the illusion were clarified.

ビッグデータの時代に入り、ビッグデータの構築・解析による成果を実社会へ還元することが課題となっている。台湾では、医療保険データが標準化され、一元的に管理されており、そのデータを用い、台湾の中国医薬大学では、7年間で1,000本以上の論文を出版し、実社会に大きなインパクトを与えつつある。日本においてもレセプト情報・特定健診等情報データベースが構築されている。本研究では、台湾及び日本の医療保険データを中心とするビッグデータを用い、宇宙要因、気象要因、大気要因とヒトの疾患の発症との関連性を検証し、自殺及び関連イベント、虚血性心疾患、及び脳血管疾患の発症予測モデルを構築する。

Three major periods in the development of urban geography and the growth in the number of urban geographers in Japan can be recognized: the first is from 1904 to 1929, the second is from 1930 to 1946, and the third from 1947 to the present.The first period was initiated by the studies of Professor N. Yamazaki, Tokyo University. This was then followed by the papers of M. Odauchi, K. Tanaka and T. Ogawa. Among these geographers, urban geography was not their specialization with the exception of M. Odauchi. Consequently, there were practically no urban specialists at this time.The second period can be subdivided into a prewar period and a wartime stagnation period in urban geographic research, The former period was started with the establishment of the Association of Japanese Geographers. The main trends in this period were morphological and quantitative analyses of urban area and the statistical analyses of urban population. There were many articles regarding urban areas in geography, but most of these articles were written by non-specialists. Geographers who concentrated their efforts on urban geography included S Kiuchi, Y. Ogasawara and K. Kagami in the latter part of the prewar period. However, the war brought about a stagnation in urban studies from about 1940 to 1946.The third period is the postwar period which was initiated by the studies on war-damaged cities by S Kiuchi, K. Inoki, E. Inami and K. Tanabe. Later, S Kiuchi published a seminal book entitled, Urban Geography, which greatly influenced the younger geographers and students. Many geographers began to specialize in this area of study as postwar interest in urbanization grew. The rapid growth can be seen by the eleven symposia on urban geography which have been held between 1953 and 1973 during the annual meetings of AJG. The studies by urban specialists cover the entire range of this field. In addition, studies on foreign cities have increased in recent years. The use of quantitative methods for urban studies has progressed recently.

We here propose a device that can display a translational force and torque using two vibration speakers. Each vibration speaker generates an asymmetric vibration when a sound with an asymmetric amplitude is input. Asymmetric vibrations induce perceived forces that pull or push a user's hand in a particular direction. The user perceives a translational force and/or torque with his/her thumb and index finger based on the direction and amplitude of each speaker's force. We conducted four evaluation experiments to evaluate the mechanical properties and the proprioceptive sensations. As result, we confirmed that the proposed device can present the translational force with a maximum value of 0.5 N and the torque with a maximum value of 9.5 N·mm.
