The purpose of this study was to determine what rationale people use to identify characteristics of automobile styling. Previously gathered data indicates that people identify a characteristic as being something that deviates from what they image to be "Average", and they describe it by its relative position to that "Average" image. To further enhance this data we generated graphical image of popular automobiles, but with exaggerated features, and interviewed people to determine if they could recognize the differences between our graphical images and what they thought the actual cars looked like. We found that in order to identify new characteristics, a person must first visualize an image of "Average" model of the car and then must vividly recall its characteristics. This ability seems to be a function of how often the actual model was observed.

A brief meeting by a few people is one of daily office works. We studied a groupware workstation for a brief meeting, and named as 'TableTop'. its prototype was developed and evaluated for confirmation of utility. In the prototype, two types of visualization by 'paper and pencil' were hypothesized as elements of a brief meeting support. Which were as follows: (1)What I write is what I see (2)What I see is what you see (by image rotation) On the evaluation, beginner could use without any trouble, and understand electronic 'paper and pencil' immediately. Especially, direct manipulation of image rotation got high evaluation as user interface. It was also found that Proxemics was useful for designing of a face to face groupware tool. Further importance of the territory in groupware was confirmed, and interaction of natural initiative was realized.

This paper concerns with the preference in singlelens reflex cameras through applying 'transaction' between man and man to between consumer and product. It was found that 'Ego-gram' and Life-style signify other sides of the attitude comparing the formula of attitude of Fishbein. Until now, preference was mainly explained by Life-style. But it was found that classifying consumers by 'Ego-gram' explains preference more properly than classifying consumers by Life-style. And if estimated items are corresponded to ego, it was found that 'natural transaction' between consumer and preference in single-lens reflex camera. As the result, the way to develop of products from the point of view of Life-style has been only method, but it is able to suggest to develop of products from the point of view of 'transaction' between consumer and product.

To Josef Albers, drawing was to be a visual formulation achieved by line, and its main concern was to present three-dimensional effect with strictly two-demensional means. Then, to use his pedagogical terminology, in drawing we learn to observe and articulate lines which make us read the inbetween-of-line. Albers' concept of drawing was formulated through his many years of teaching the drawing courses first in the Bauhaus and then in Black Mountain College and the Department of Design at Yale. Besides instructing the drawing courses, Albers' also made numerous studies of linear constructions, some of which were executed as the GRAPHIC TECTONICS series in 1942 and others begun as the STRUCTURAL CONSTELLATIONS series in the early 1950s. The purpose of this paper is to trace the development of Albers' drawing courses and to examine the interrelation between the content of his drawing courses and the content of these linear constructions series.

The changes of properties of tableware design is made clear by using 466 samples extracted from FUZOKU-GA in Middle and Modern Ages (from Heian till Edo period) in Japan. Study is dealt with both quantity data as macro sight and detained observation as a micro sight. Result is as follows; (1)The origin of high-base style wooden bowl is related to the establishment of eating style of holding and lifting a bowl. (2)Wooden bowl which was used for a long peried among all social positions is so called a typical living ware. (3)Reason of the popularity of wooden bowl is conceived to come from application ability to various usages.

So far, some studies of image characteristics and inference have been done. However, thoes methods obtain results convergently, not divergently. In this study we develop a system in which results are obtained divergently using 3 genetics algorithm that bases on the the theory of a life's evolution (selection and mutation), and compare these results with those obtained by a neural network using some sample concepts. Subsequently, we confirm the viability of the system using the genetics algorithm. Further, we develop a system connecting genetics algorithm and neural network in paralle, and as a result we confirm that this system gets results has advantages of both of methods, and can controls these advantages by a parameter.
