We propose a Japanese font automatic creating system reflecting user's Kansei. In the system, a user inputs the impression of a font to create. Since a user does not have to do direct design work, a user without special design skill can easily obtain various fonts reflecting his/her Kansei. The proposed system operates based on the genetic algorithm. The genetic algorithm consists of two parts: a font creation part and a font evaluation part. By repetition of creation and evaluation, the system outputs a font which meets the demand of a user. In addition, by repetition of the genetic algorithm, various fonts are outputted. Furthermore, the system has the learning ability to reflect each user's Kansei. Through the experiment, we have confirmed the availability of the system, such as the diversity of created fonts and the satisfaction of each user.

In connection with progress of technology, products with good function and performance are thrown into the market one after another and they give great influences on business or life. On the other hand, however they may have good quality, they cannot be necessarily accepted in a market and obtain customer satisfaction. In this paper, we argued about effects of customers' sensitivity to products and technology on intension of purchase and quality prediction. At first, we defined a concept of ‘quality of products’ and ‘customer's prediction to quality’, and modeled ‘intension of purchase’ and ‘customer satisfaction’ with them. Next, we analyzed influence of customers' sensitivity to products and technology on ‘customer's prediction to quality’ and ‘intension of purchase’ by experiments using questionnaires. At last, we proposed ways of offering information according to customers' sensitivity. They might give good effects on customer satisfaction.

We conducted a questionnaire survey of the appreciators for the purpose of finding hypotheses used when studying the psychological structure of appreciating works of art. As a result, the following tendencies were observed. 1) The degree of good impression for works of art is strongly influenced by beautifulness. Especially, this tendency is conspicuous for appreciators who have no education in art. 2) When appreciators pay attention to a part of works of art, the reasons for attention are; the content of reproduction, the technique of execution, and the visual effects such as beautifulness of colors or shapes. 3) How appreciators evaluate the colors in pictures and the massiveness in sculptures is strongly influenced whether they had education in art or not. 4) The following factors have a great influence on the appreciation of works of art;“elaborateness”, “complicatedness”, “interest”.

In this paper I will show the essential factors of Kansei evaluation in a participatory productive process based on unique characteristics of an object through the comparison with the SD method. The Kansei evaluation in a participatory productive process should consists of activity of Kansei, free access to an object, unrestricted expression, intention to show diverse individual sensibility, and so on. In this Kansei evaluation, people evaluate what is generated by interaction between an object and their Kansei. The interaction as a workshop held in Ayabe, Kyoto in 2003 shows, can be accelerated by (1) different viewpoints, (2) direct experience and related information, (3) communication between participa

Bellsystem24, Inc. tried out the field test with Matsushita Electric Works, Ltd. to develop a new telephone communication service with elderly people. This paper reports on the analysis of data relating to the quality of life (QOL) on elderly people who participated in the test. The test subjects were 46 elderly people. We tried to keep and promote their QOL by calling them regularly from the call center, not only did we collect their daily vital data (blood pressure, pulse rate, and temperature), but also we had some talk. To verify the effect of this test, we took a questionnaire consisted of mental and physical aspects before and after the test, and compared the before-test data with the after-test one. As a result, women showed the significant improvement on their mental aspect, especially with the women living alone.

An interface between a human and an intelligent machine in a shared daily space, in which the intelligent machine follows instructions by the sound pressure of an ordinary human voice, is considered here. This interface is effective for the disabled who have difficulty with linguistic expression. The intelligent machine's cooperative movements are required to take account of the human's state of mind to serve effectively as his or her companion. In this paper, the patterns of intelligent machine motion are determined by adopting transfer functions that consider sound pressure directing operation as input, and the target speed of the intelligent machine as output. By changing transfer functions or adjustable parameters, different human psychological influences are expected. Motion properties of intelligent machines, which are appropriate for human states of mind, are examined using the SD method. As a result, it is clarified that human emotions concerning the intelligent machine motion are represented by the factors of “mild”, “lively”, “comfortable”and “interesting”. In addition, two patterns of transfer function and parameter th at can form desirablemovements considering human psvchology are identified.

The purpose of this study is to clarify the mechanism of smiles by measuring facial muscle activities and facial surface transformation. We made it possible that the strength of the smile was fixed the same by using the biofeedback technique. And facial muscle activities that caused a change on skin surface were measured by surface electromyography and the physiological mechanism of the smile was examined. It became clear that the muscle activities of the risorius and depressor labii inferioris had a significant effect on the formation of the smiling faces. We confirmed that a change of the eye that is the symbol of the smile depended on the compression of the skin by the picture analysis of the face. The internal and external relations to make the characteristics of the smile were explained.

A subjective similarity estimation model of apparel product images using the image feature is proposed in order to retrieve apparel products by subjective similarity, and the validity is inspected. The subjective similarity of apparel products image was investigated by paired comparison test. The relationship between the subjective similarity and the design elements was analyzed by multidimensional scale method. Fractal dimension and silhouette geometry were adopted as the quantities of image feature. A subjective similarity estimation model was developed using multidimensional index space. As results, high search effciency was obtained by proposed method than conventionals tudies.

The beauty of language structure has been evaluated by the subjective sensitivity with intuition, and experience. This i ndicates that beauty cannot be quantitatively evaluated. The purpose of this study is to propose the quantitative evaluation method for the beauty. The establishment of the quantitative evaluation method gives us an information concerning the designing of the more beautiful structure. The targets used were a hiragana drawn by four persons, three beginners and one calligrapher with a high skill. In the quantification technique, brush motions under drawing were measured by a motion capture system. Four types of hiragana were also evaluated by sensory test. Compared the brush motions with the sensory testing results, it was concluded that some composition elements of beauty could be quantitatively evaluated by the brush motion and geometry of hiragana.

Colic crying, which is a baby's abnormal crying induced by unknown causes, is a typical example of sounds giving unpleasant impressions to listeners. Recently, Mukai et al. suggested that the colic crying would cause the child abuse because of its unpleasantness. In this paper, we propose the extended pitch perturbation quotient (ePPQ) for the evaluation of unpleasantness of crying. It is shown that the ePPQ is an index to quantify instability of fundamental periods, which seems to be cause of unpleasantness of colic crying. The ePPQ for colic crying is significantly higher than that for crying cured by operation. Furthermore, as a result of subjective evaluations, it seems that there is a tendency for the scale of unpleasantness to be high when the ePPQ is high. Therefore, it is considered that the ePPQ is a useful index for evaluating unpleasantness for crying.

We have developed the learning tools for network communication. It is very important for students to improve practical use of both computer and web site information. They have to learn network security and morals by practicing some existent communication tools. Such an experiential learning is useful to learn some new computer systems. However, the equipment of LAN system in high schools has not widely constructed yet and the appropriate learning tools are not fully equipped. The developed learning tools are effective under any circumstances, even if network has not yet equipped in the school. We have tried to evaluate the tools by students in our university. As a result, we find that the learning tools function almost in order
