A sun visor has been used only for the purpose of interrupting direct sunshine. Investigation, therefore, has not been made to be on the feeling of touch of the sun visor. In this study, the feeling of touch of sun visor installed in the present automobile was investigated. To clarify the relation between the sense of touch and the mechanical and physical quantity of the sun visor, prototype products of the sun visor of the same shape were made. Surface characteristics and cold feel characteristic of materials were measured by the KES system. In addition, we investigated the relation between the surface property and the sense of touch of various materials. The correlation between favorability and WC, RC, SMD was high on the sun visor prototype. As a result, it was clarified that materials whose surfaces were very smooth and soft were favorable. Those materials consist of leather and moquette. Conversely, the material sensed hard was not favorable. The relation between the mechanical and the physical properties of various materials, and the favorability was able to be approximated by the equation (1).<BR><I>Favorability=2.482+0.02791LC+0.293WC-0.264RC+0.0688MIU-0.0966MMD+0.0253SMD-0.0288qmax</I>(1)

This paper proposes a method of simulating breast shape modification by wearing a brassiere. For this purpose a three-dimensional (3D) human body shape model developed by one of the authors is used. The model is made of a bi-cubic B-spline surface and its control points can describe a woman's trunk shape by fitting it to plenty of her body surface points. Corresponding control points among models have the same meaning in the sense that they form the same region on the different women's body surfaces. This feature enables us to compare and analyze a local body shape using a subset of control points selected appropriately. Forty-nine control points were determined to analyze breast shape of any woman. One hundred forty-two Japanese women aged 20's to 50's (brassiere size ranged from A70 to E70) were measured by means of an optical range finder before and after putting on a brassiere. We also categorized softness of their breasts into three classes; "soft", "medial", and "stiff". The multiple regression analysis established the relationship between the position of the control points on the models before and while wearing a brassiere using softness as a parameter. The best regression function was chosen among prepared 15 ones for each coordinate of every control points and was applied to simulation of brassiere-wearing breast figures based on the position of the control points before putting on it. The results showed that it is possible to estimate the body shape when wearing a brassiere. The same was confirmed based on average errors between silhouettes of brassiere-wearing and simulated breasts.

The purpose of this research is to analyze Japanese women's breast shape based on body surface data described by a three-dimensional (3-D) human body shape model with a bi-cubic B-spline structure and to classify them. The data used for analysis were forty-nine 3-D control points selected from the right breast area on the model surface for each of 556 Japanese women aged 19 through 63 years. We examined the covariance matrix of the data using the principal component analysis method after normalization of their 3-D coordinates with the bust width for reducing the size factor. As a result, we obtained four principal components, which described 77% of breast shape. Then Japanese women's breast shape was classified into five classes in the principal component space using the first, second, third and forth-principal component scores. They could cover 92% of Japanese women's breasts. Therefore, we tried to analyze breast shape by clustering in order to classify all the breasts. For the cluster analysis we prepared two kinds of data; (1) principal component scores and (2) the normalized scores (μ=0, σ=1) of (1). With the clustering (1) and (2) we obtained four classes and five classes, respectively. Properties and advantages of the three kinds of classifications were also discussed. The classification of the principal component space is based on standard deviations of principal component scores, and therefore the resultant classes do not have clear boundaries. The classification according to the cluster analysis (1) can reflect the actual distribution of breast shape. In contrast the clustering (2) gives classification reflecting more principal components and tending to generate more classes than the clustering (1).

The hand is one of the important qualities of bath towels. It is interesting to study what physical properties of bath towels correlate to their hand. In this paper, the relationship between the sensory values for the good feel and physical properties of twelve bath towels was studied by means of the principle regression analysis and the correlation analysis. The results are as follows.(1) As a result of principal component analysis, it was found that two principal component “good in touch” and “sturdy and drying property” were chosen to represent the hand of bath towel.(2) The compression feeling was affected by compression properties((To-TM), compression ratio, compression energy, and recovery energy). And the softness feeling was affected by the friction property(MMD), and the warmth by the thermal property(q-max).

To examine the aesthetic properties of pantyhose, an image analysis and wear experiment were carried out. We analyzed both the area ratio of light, medium, and dark lightness areas and the position of three areas in the distribution of lightness difference between legs with and without pantyhose fabric. The data was used to determine what effect these two variables have on the visual appeal of legs in pantyhose. Moreover, we examined the relationship between pantyhose size and women’s leg size on the attractiveness of legs in pantyhose made from single covered yarn with colored polyurethane core yarn. The results showed that, for the enhanced visual appeal of legs in pantyhose, (1) the area ratio and position of three areas in the distribution of lightness difference were very important factors; (2) it was desirable to design and produce the appropriate size of pantyhose for various sized legs in order to enhance their attractiveness.

To improve the aesthetic appeal of pantyhose fabric, a new product was designed and developed and a wear experiment were conducted. We examined the gradational effects of lightness and visual impression of circular plain knitted fabrics made from novel single covered yarn composed of color polyurethane core yarn and uncolored nylon covering yarn with and without dyeing. The results indicate that, in terms of sheerness and gradation of lightness, for pantyhose samples made from single covered yarn, a combination of a coarser color polyurethane core yarn and a finer nylon covering yarn is preferable to that of a finer color polyurethane core yarn and a coarser nylon covering yarn. The gradational effects of lightness on the aesthetic appeal of legs clad in pantyhose are greatly influenced by the size and color of both core and covering yarns in the single covered yarn. Color polyurethane core yarn is useful for improving the distribution of lightness difference between legs with and without the pantyhose fabric on the entire leg wearing pantyhose. It was found that not only the sheerness but also the gradational effects of lightness for three-dimensional appeal of pantyhose is an important aesthetic property in beautifying legs clad in them.
