[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a texture chart of an object, in particular, a texture chart which can be used to support interior design using building materials, interior materials, furniture, and the like, a method of producing the same, and design support using the chart. It concerns the device.

2. Description of the Related Art In recent years, a wide variety of products have been supplied as building materials such as wallpaper, flooring materials, and tiles, or as interior materials. Furniture such as sofas and cabinets, as well as curtains and carpets, are also diversifying. Moreover, by freely combining the materials used, surface finishing methods, surface patterns, colors, and the like, the possibilities for developing new products are infinitely expanding. In this way, the variety of products that can be selected will increase the degree of freedom in interior design,
On the other hand, interior design is becoming more sophisticated and complicated.

[0003] An interior designer selects a product suitable for a customer's request from among such versatile products, and proceeds with interior design work. However, in general, customer requests are often given as psychological images. For example, "I want a room that feels warm"
It is given a vague psychological image such as "I like a room with a fluffy feeling" or "I want a room with an exciting feeling". In the present specification, such a psychological image expressed in words is referred to as “texture”. Conventionally, interior designers have subjectively selected products based on customer demands for such “texture”.

[0004]

In recent years, the demand for interior design has been increasing more and more.
The criteria for choosing furniture, etc., depend entirely on the subjectivity of interior designers. This is because the "texture" requested by the customer probably includes fuzzy elements, which makes it difficult to handle objectively. Regarding color, attempts have been made to objectively relate such a psychological image of a person to a specific color. For example, Japanese Patent Publication No. Sho 56-46082 discloses a color image scale in which a language corresponding to a certain psychological image is related to a specific color. However, regarding interior design in general, the psychological image of human beings,
The method of objectively handling the relationship with the actual product has not yet been established.

[0005] Therefore, an object of the present invention is to provide a tool that can objectively link a "texture" based on human subjectivity with an actual product.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the illustrated embodiments. FIG. 1 is a diagram for explaining a basic concept of a texture chart according to the present invention. When a human touches the object 10, first, the properties of the object 10 are captured by the perception 20. That is, the properties of the object 10 can be captured by the action of so-called five senses such as sight, hearing, touch, taste, and smell. Then, a psychological image 30 is created based on such perception. However, this psychological image 30 is obtained as a result of the intrinsic mental activity of a human, and it is difficult to transmit this directly to another human. Therefore, in the present invention, the psychological image 30 is expressed and handled in words such as "warm feeling", "fluffy feeling", and "stimulating feeling". In this specification, the expression of the psychological image 30 in words will be referred to as “texture”.

The texture chart C according to the present invention expresses the psychological image 30 in a two-dimensional coordinate system.
As shown in FIG. 1, the texture chart C is a coordinate system in which a visual texture value x is set on a horizontal axis and a tactile texture value y is set on a vertical axis. It corresponds to a specific texture, that is, a psychological image 30. In the example shown in the figure, the area a has a “feeling feeling”, the area b has a “fluffy feeling”, the area c has a “feeling calm”,
The texture "stimulating feeling" is defined in the area d.

One object is associated with a predetermined coordinate position in the texture chart. For example, a certain object 10 is associated with a corresponding point Q shown in the figure, and is characterized as an object having a psychological image such as a combination of "a feeling that was sharp" and "a stimulating feeling". . The corresponding point of an object 10 is represented by a texture chart C.
Which of the above positions is plotted can be determined as follows. First, the physical properties of the object 10 are measured,
Obtain the physical quantity M. The physical quantity M is a light reflectance, a transmittance, a spectral reflectance (a physical quantity corresponding to a color, and may be a numerical value such as a tristimulus value or lightness / saturation / hue of a Munsell color system), and a surface. It is an amount that can be expressed as an objective numerical value such as roughness, friction coefficient, surface hardness (pencil hardness, rubber hardness, Vickers hardness, etc.), elastic constant (for example, Young's modulus), thermal conductivity, specific heat, density,. Subsequently, the perception parameter P is obtained by applying the conversion function f to these physical quantities M. This perceptual parameter P is a numerical representation of the human perception 20. The present invention relates to building materials, interior materials,
The main purpose is to support interior design using furniture and the like, and a psychological image of an object to be subjected to the interior design is obtained mainly from sight and touch. Therefore, the perceptual parameter P is composed of the visual parameter Px and the tactile parameter Py. In this embodiment, three elements of glossiness PX1, unevenness PX2, and transparency PX3 are used as visual parameters Px, and thermal sensation PY1, coarse smoothness PY2, and softness PY are used as tactile parameters Py.
3, the three elements are used. Finally, a conversion function g is applied to the visual parameter Px and the haptic parameter Py to obtain a visual texture value x and a haptic texture value y. Thus, if the (x, y) coordinate value is obtained, the corresponding point Q of the object 10 is obtained.

The basic concept of the texture chart C has been described above. Next, a method of creating the texture chart C will be described in detail with reference to specific examples. First, it is necessary to define a conversion function f in advance. The conversion function f is defined as a predetermined physical quantity M1,
A function for determining a value of a predetermined perceptual parameter P based on M2, M3,..., Mn. That is, it is a function that gives P = f (M1, M2, M3,..., Mn). In this embodiment, six perceptual parameters of glossiness PX1, unevenness PX2, transparency PX3, warm / cool sensation PY1, coarse / smoothness PY2, and hardness / softness PY3 are used. Six conversion functions f1 to f6 are defined. Such a conversion function f is
It can be defined in the following way. For example, a case in which a conversion function f1 for obtaining the gloss PX1 is defined will be described as an example. In this case, first, create some model functions. For example, as physical quantities likely to affect the gloss PX1, four physical quantities such as light reflectance M1, transmittance M2, surface roughness M3, and surface hardness M4 are taken, and PX1 = f11 (M1, M2, M3, M4) = M1 + M2 + M3 + M4 It would be possible to create a model function f11 such that the sum of these four physical quantities is the gloss PX1, and PX1 = f12 (M1, M2, M3, M4) = aM1 + bM2 + cM3 + dM4. The predetermined four coefficients a, b, c, and
It would also be possible to create a model function f12 such that the sum value weighted by multiplying by d, that is, the linear combination value is the gloss PX1. Alternatively, a model function f13 such as PX1 = f13 (M1, M2, M3, M5) = aM1 + bM2 + cM3 + dM5 can be created by using the density M5 instead of the surface hardness M4. Alternatively, a simple model function f14 such as PX1 = f14 (M1) = M1 may be created using only the light reflectance M1.

The physical quantities M1, M2,... Can be arbitrarily selected as required. As a result of various experiments, the quantities relating to color (spectral reflectance, tristimulus value, Munsell value, etc.) are different from other physical quantities. It is known that it is better to handle the garbage separately from the viewpoint of texture display and the like. In other words, the texture (equivalent to a psychological image) felt by humans can be broadly divided into two types: A: texture caused by color perception B: texture caused by something other than color perception The ratios are also substantially the same for both (A, B). Therefore, only B is displayed and handled in two-dimensional coordinates, and A is ignored if the color is not so important.

A is handled as coordinates independent of B. For example, Pz1 = X / (X + Y + Z) (Pz1, Pz2, Pz3 are color coordinate values) Pz2 = Y / (X + Y + Z) (X, Y, Z are tristimulus values) Pz3 = Y Assuming that Z = g3 (Pz1, Pz2, Pz3) = (Pz1 + Pz2 + Pz3) / 3, the color vision textures Z are synthesized, and these are orthogonalized to the two-dimensional coordinates (X, Y) expressing B, and the three-dimensional space (X, (Y, Z) to display the texture.

Regarding A, the reference is made separately by referring to samples such as color photographs and color charts. It is preferable to use such methods in terms of accurate classification and display of texture, correspondence with psychological images, ease of handling in design practice, and the like. However, it is not entirely denied that A and B are mixed and handled. For example, the thermal sensation Py1 has a correlation with the hue (orange / red feels warm, and blue / green feels cool). , Py1 as part of the physical quantity for obtaining the color coordinate values X / (X + Y + Z), Y /
Use of (X + Y + Z) may be effective.

Subsequently, several objects are prepared. Here, since an example of creating a texture chart for wallpaper will be described, it is assumed that several types of wallpapers are prepared. Then, some subjects are allowed to show and touch each wallpaper, and subjectively say the value of the glossiness PX1. At this time, the sample wallpaper considered to be the most glossy is, for example, glossy PX1 = 10, the sample wallpaper considered to be the least glossy is set to glossy PX1 = 0, and subjectively within the range of 10-0. It is better to determine the value of typical gloss PX1. More preferably, a sample wallpaper corresponding to the intermediate value Px1 = 5 should be prepared so that the subjective glossiness value can be easily determined. Thus, the subjective glossiness values of a plurality of subjects are averaged, and the subjective glossiness P for each wallpaper is averaged.
Find the value of X1.

On the other hand, based on the created model functions f11 to f14, an objective value of glossiness PX1 for each wallpaper is obtained. This can be obtained objectively by measuring the physical quantity of each wallpaper. For example, the objective glossiness PX1 based on the model function f11 is obtained by measuring four physical quantities of each wallpaper, that is, light reflectance M1, transmittance M2, surface roughness M3, and surface hardness M4, and PX1 = M1 + M2 + M3 + M4. It is obtained by performing an operation.

Thus, the gloss P of the same wallpaper
As X1, a subjective value (a value obtained by presenting the wallpaper to the subject) and an objective value (a value obtained by applying a model function to the measured physical quantity) are obtained. Therefore,
When examining the correlation between the two, for example, a graph as shown in FIG. 2 is obtained. Here, graph (a) is a correlation with an objective value obtained by applying a model function f11, graph (b) is a correlation with an objective value obtained by applying a model function f12, and graph (c) is a model function. Graph (d) shows the correlation with the objective value obtained by applying the model function f14. The cross in each graph corresponds to one wallpaper. In this example, the graph (d) has a low correlation, the graph (b) has a high correlation, and the graphs (a) and (c) show an intermediate correlation. Therefore, the created four model functions f11 to f11
In 14, the function f12 is most suitable for the conversion function. Further, even with the same function f12, the count values a to
By changing d, the correlation changes. Therefore, a function in which the count value is variously changed is created by repeating trial and error, and the function having the highest correlation may be defined as the conversion function. In addition, as a method of extracting the one having the highest correlation with the subjective value from the linear combination values such as the function f12,
In some cases, a mathematical technique known as principal component analysis is effective. Specifically, by this principal component analysis method, first principal components, second principal components,..., And other principal components (values weighted so as to maximize the variance of the linear combination value) are obtained.
What is necessary is just to evaluate the correlation between these and the subjective value. that's all,
Although the method of defining the conversion function for obtaining the gloss PX1 has been described, the conversion function for obtaining other perceptual parameters can be defined in exactly the same manner.

In this way, if six conversion functions f1 to f6 are defined in advance, the required physical quantity is measured for an arbitrary wallpaper, and this conversion function is applied to obtain six perceptual parameters, that is, six perceptual parameters. , Glossiness PX1, unevenness PX2, transparency PX3, warm / cool sensation PY1, coarse smoothness PY2, and hardness / softness PY3. Instead of measuring the physical quantity for each wallpaper, the subjects were directly determined perceptual parameters such as the glossiness Px1 and the unevenness Px2 for each wallpaper, and the average of the subjective values directly determined by a plurality of subjects was calculated. It can also be the value of a perceptual parameter. According to this method, a measuring device or the like for measuring a physical quantity is unnecessary.

Subsequently, a conversion function g is applied to these six perceptual parameters to obtain a visual texture value x and a tactile texture value y. That is, two conversion functions g1 and g2 are defined in advance, and x = g1 (PX1, PX2, PX3) y = g2 (PY1, PY2, PY3) as the visual texture value x and the tactile texture value y Ask for. Here, the visual texture value x is a value obtained by compressing information of three visual parameters Px, and the tactile texture value y is 3
This is a value obtained by compressing information of two haptic parameters Py. Therefore, the conversion functions g1 and g2 may be any functions as long as the functions are suitable for performing the information compression. However, usually, the functions g1 and g2 are generally used in terms of calculation convenience and ease of handling. , It is effective to take a linear combination value. In this embodiment, the conversion functions g1 and g2 are both functions for obtaining a simple average. That is, x and y are obtained by the calculation of x = (PX1 + PX2 + PX3) / 3 y = (PY1 + PY2 + PY3) / 3.

After all, given one type of wallpaper,
The visual texture value x and the tactile texture value y for the wallpaper are determined. Therefore, if a two-dimensional coordinate system is defined on the texture chart C, the corresponding point Q for a specific wallpaper is obtained as a point plotted on the coordinate value (x, y). In this way, the corresponding points Q for a plurality of wallpapers are plotted on the texture chart C, and an index indicating the wallpaper is arranged at the position of each corresponding point Q. For example, a photo of the wallpaper or a product number display may be pasted at the position of the corresponding point Q.

By the way, a specific area of the texture chart C created in this way can be associated with a specific texture. For example, in the example shown in FIG. 1, as described above, the area “a” has a “crisp feeling”, the area “b” has a “fluffy” feeling, the area “c” has a “soft feeling”, and the area d has a “stimulating feeling”. Is defined. What kind of texture is defined in which area is determined by the conversion function g
1 and g2, but the same conversion function g
As long as 1, g2 is used, the same texture can be defined in the same region. Therefore, once the conversion functions g1 and g2 are defined, one sample texture chart C is created by applying the conversion functions g1 and g2. Then, the texture of each area is defined while looking at the index (for example, a picture of the wallpaper) arranged on the chart. The texture thus defined can be used in common for different texture charts as long as the same conversion function is used.

FIG. 3 shows an example of the texture chart thus created. The horizontal axis defines the visual texture value x, and the vertical axis defines the tactile texture value y. In this example, each of the visual parameters Px is defined as a numerical value in the range of −3 <Px <+3, and each of the haptic parameters Py is −
It is defined as a numerical value in the range of 2 <Py <+2. More specifically, regarding the visual parameter Px, the value of the gloss PX1 in the case of the most gloss is set to -3, the value of the gloss PX1 in the case of the least gloss is set to +3, and The value of PX2 is +3, the value of the unevenness PX2 when there is the least unevenness is -3, the value of the transparent PX3 when it is the most transparent is -3, and the value of the transparent PX3 when it is the most opaque is +3. . Regarding the tactile parameter Py, the value of the thermal sensation PY1 in the warmest case is +2, the value of the thermal sensation PY1 in the coldest is −2, and the value of the coarse and smooth sensation PY2 in the coarsest is +2. The value of rough smoothness PY2 in the case of smoothness is -2, and the value of hard softness PY3 in the softest case is +.
2. The value of the hard and soft feeling PY3 in the hardest case is -2.
Therefore, the conversion functions f1 to f3 are all -3 to
It has a function value of +3, and the conversion functions f4 to f6 are all defined to have function values of -2 to +2.

As a result of applying the conversion functions f1 to f3 to the physical quantity measured for a certain wallpaper, for example, a function value of glossiness PX1 = + 1, unevenness PX2 = -2, and transparency PX3 = 0 was obtained. Then, the visual texture value x becomes x = -1 on average. Also, the conversion functions f4 to f6
As a result, for example, assuming that the function values of thermal sensation PY1 = + 1, coarse smoothness PY2 = + 2, and soft / soft sensation PY3 = + 1.5 are obtained, the tactile texture value y is obtained by averaging these values y = +
1.5. Thus, for this wallpaper, the corresponding point Q (-1, + 1.5) can be plotted as shown in the figure.

The scale of glossiness, unevenness, and transparency is displayed at the lower part of the texture chart, and the scales of warm / cool, rough smoothness, and softness are displayed at the right part. I have. By displaying such a scale,
It is possible to grasp what value the predetermined corresponding point Q corresponds to in each perceptual parameter. For example, in the case of the example in the figure, the corresponding point Q has a visual texture value x = −1,
It can be seen that this value corresponds to the perception that there is a slight glossiness, a slight unevenness, and a slight transparency. Also, the corresponding point Q is about tactile texture value y = + 1.5, and it is understood that this value corresponds to the perception that it is considerably warm, fairly coarse, and fairly soft. of course,
The individual perception of the corresponding point Q does not coincide with the individual perception of the original wallpaper. For example,
As described above, the glossiness of the original wallpaper PX1 = + 1,
It is different from the scale value -1 of the corresponding point Q. This is natural since the corresponding point Q is a compression of the individual perception information about the original wallpaper. However, by providing such a scale, it is possible to know an indication as to what value a certain corresponding point Q corresponds to in glossiness and to what value in hard and soft feeling. So convenient.

Next, the texture defined in the texture chart shown in FIG. 3 will be described. As described above, the texture expressing the psychological image in words is defined in each area of the texture chart. However, in this embodiment, each texture is defined not in a closed region but in a direction. That is, the texture “ADAPT” is in the positive direction (right direction in the figure) of the visual texture value x, the texture “ATTRACT” is in the negative direction (left direction in the figure), and the tactile texture value y is In the positive direction (upward in the figure), "INTIMAT
The texture “E” is “INC” in the negative direction (downward in the figure).
The texture "ENTIVE" is defined.
The position of the origin O is the neutral point of these textures, and the origin O
As the distance increases, the degree of texture defined in each axis direction increases. Here, the four textures expressed by English words correspond to the following psychological images in Japanese. (1) "ADAPT": moist, rough, mellow, adaptable, gentle, dull, ... (2) "ATTRACT": clean, slippery, shiny, edgy, sharp, shining, sharp, …… (3) “INTIMATE”: warm, fresh, soft, fluffy, gentle, intimate,… (4) “INCENTIVE”: want to fill, smooth,
Hard, crisp, harsh, stimulating ... For example, the corresponding point Q is quite "INTIMATE"
Therefore, it expresses a slightly "ATTRACT" texture, and the psychological image in Japanese corresponds to the expression "warm and refreshing" or "appears fluffy".

FIG. 4 shows texture charts actually created for various types of wallpaper. At the corresponding point position of each wallpaper (corresponding to the position of the corresponding point Q in FIG. 3), a small piece of a photograph of the wallpaper is pasted. By creating such a texture chart, it becomes very easy for the interior designer to select the wallpaper that matches the psychological image required by the customer. For example, if a customer requests “Sparkling, exciting image wallpaper,” a wallpaper with the texture “ATTRACT” and “INCENTIVE”
For example, the wallpaper shown in the photo W1 in FIG. 4 may be selected. Here, when this wallpaper is presented to the customer, and a request is made that “a little more gentle is better”, the photograph W2 arranged on the “ADAPT” side rather than the photograph W1 may be presented. . In this way, if the user is not satisfied with the wallpaper once selected, the user can move the position on the texture chart in a direction that matches the psychological image of the customer and select a new wallpaper. Thus, it is possible to perform a systematic selection operation.

Conversely, by using this texture chart, it is possible to know what kind of psychological image a particular wallpaper corresponds to. For example, it can be seen that the wallpaper shown in the photo W3 in FIG. 4 corresponds to a psychological image of "moist, mellow, and soft." It would also be possible to perform total coordination in connection with another texture chart. For example, it is assumed that the wallpaper shown in the photo W3 is selected while looking at the wallpaper texture chart shown in FIG. Then, consider the case of choosing a curtain with the same image as this wallpaper. In this case, a curtain located at substantially the same coordinate position as the selected wallpaper, that is, the curtain shown in the photograph W4 may be selected from the curtain texture chart shown in FIG. It is also possible to generate a variation having the same texture as one wallpaper. For example, the coordinate values of the wallpaper shown in the photograph W3 in FIG. 4 are (+2, +1.5). Here, + of the X coordinate value
2 is glossiness PX1 = + 3, unevenness PX2 = + 2, transparency P
Suppose that the value was obtained as an average of X3 = + 1. However, the visual parameter P for obtaining the same X coordinate value +2
The combination of x is not limited to this combination. For example, gloss PX1 = + 2, unevenness PX2 = + 2, transparency P
Even with the combination of X3 = + 2, the average value is +2, and the same texture can be obtained. As described above, the texture chart is useful even in considering variations of variations having the same texture.

Although the present invention has been described with reference to the wallpaper texture chart as an example, the present invention is applicable not only to wallpaper but also to any object. In particular, if applied to products such as building materials, interior materials, and furniture, they will greatly contribute to the support of interior design. Further, the texture chart of the present invention is not only applied to individual objects, but is also applicable to a set of objects. For example, it can be applied to the entire interior decoration. That is, it is possible to prepare a texture chart to which a photograph of the room is attached, and to grasp the psychological image of the entire room. In addition, not only a texture chart for each product such as a wallpaper texture chart and a curtain texture chart, but also a texture chart for a material, for example, could be created. For example, arranging materials such as stainless steel, wood, plastic, plaster, tatami, stone, concrete, paper, cloth, glass, etc. in one texture chart will help to grasp the image of each material. Further, in the above-described embodiment, the photographs of the individual objects are pasted on the texture chart, but it is not always necessary to paste the photographs. In short, any index indicating the specific object may be arranged at the corresponding point obtained for the specific object. For example, in the example shown in FIG.
Instead of attaching a wallpaper picture to each corresponding point, the product number (four-digit number) of each wallpaper is described. However, it is preferable to attach a photo because it is the easiest to visually grasp.

In the above embodiment, as shown in FIG. 1, the physical quantity M of the object 10 is measured, and the physical quantity M is measured.
Although the perceptual parameter P is obtained by applying the conversion function f to, the perceptual parameter P can be obtained directly from the object 10 as shown by the dashed line in the figure. In this case, the object 10 is presented to the subject, and the value of the glossiness PX1, the value of the unevenness PX2,...
At this time, it is preferable to take the average of the values of several subjects. As described above, the minimum value and the maximum value of each value are determined in advance, and the values of a plurality of subjects are distributed in the same numerical range. In this way, if the perceptual parameter P is subjectively determined for all objects to be plotted on the texture chart, there is no need to measure the physical quantity M. However, in this method, when a new object is to be plotted on the texture chart, it is necessary to perform subjective determination of perceptual parameters by several subjects at all times. In contrast,
In the method for measuring the physical quantity M described above, once the conversion function f is defined, no test subject is required thereafter, and a new object can be plotted on the texture chart only by performing objective processing. There are benefits.

The texture chart according to the present invention and the method for producing the same have been described above. Finally, an embodiment of a design support apparatus using the texture chart will be described. FIG. 7 is a block diagram showing the basic configuration of this design support apparatus.
This device has a database of information on products such as building materials and interior materials, and can display a texture chart on a display screen based on this database. That is, the storage device 40 stores, for each product, a product code for specifying the product, the visual parameter value Px and the tactile parameter value Py of the product, the visual texture value x and the tactile texture value y of the product, Further, if necessary, image data of the product is held as a database. On the display screen of the display device 50,
A two-dimensional coordinate system is defined with the visual texture value x on the horizontal axis and the tactile texture value on the vertical axis, and a texture chart is displayed based on the database in the storage device 40. The input device 60 has a function of inputting various commands and indicating a predetermined point on a two-dimensional coordinate system defined on the display screen of the display device 50. Then, the search device 70 searches the database in the storage device 40 for a product having the visual texture value x and the tactile texture value y corresponding to the coordinate value of the predetermined point designated by the input device 60, and determines the result. It has a function to output. Control device 8
Numeral 0 is a device for controlling these devices in a centralized manner.

The specific hardware configuration of the design support apparatus can be realized using a computer. That is, the storage device 40 can be realized by an internal memory or an external storage device for the computer, the display device 50 can be realized by a display device such as a CRT connected to the computer, and the input device 60 can be realized by the computer. It can be realized by input devices such as a connected keyboard, mouse, and light pen. Further, the search device 70 and the control device 80 can be realized by the CPU of the computer and specific software for operating the CPU.

This design support device has a function of displaying the above-mentioned texture chart on a display screen. For example, in the storage device 40, it is assumed that data about a large number of wallpapers, data about a large number of curtains, data about a large number of flooring materials, and the like are prepared as a database, and these can be classified by product codes. Let's say When the designer gives a command to display a texture chart of the wallpaper from the input device 60, the control device 80
, Data about the wallpaper can be extracted from the database, and the corresponding points for each wallpaper can be plotted on the display screen of the display device 50. Here, if image data for each wallpaper is prepared in the storage device 40, an image of this wallpaper can be displayed at each corresponding point on the texture chart. After all, an equivalent to the texture chart shown in FIG. 4 can be obtained on the display screen of the display device 50.

Since this design support apparatus uses a computer, various other convenient uses are conceivable. For example, when the input device 60 indicates one point R on the texture chart, the search device 70
Products with (x, y) combinations that are close to the coordinate values of
It is also possible to search from a database in the storage device 40 and display the search result on a display screen. Also,
It would be possible to display the perceptual parameters for this product, and if the values of the physical quantities on which the perceptual parameters were determined were prepared in a database,
It is also possible to display this physical quantity. Conversely, if a product code is input from the input device 60, the corresponding product can be plotted on the texture chart and various data on the product can be displayed. Alternatively, after selecting one wallpaper from the wallpaper texture chart,
A process of searching for a curtain having the same texture can also be performed. Further, it is possible to search for variations of products having different glossiness and unevenness while having the same texture, and to output physical quantities for designing these products. Alternatively, the two-dimensional coordinate system represented by the visual texture value x and the tactile texture value y is divided into a plurality of regions,
If each area is displayed in different colors, the area with the same color can be grasped as an area having a similar psychological image. In this way, the psychological image can be classified and grasped as a color region on the display, and the corresponding product can be plotted and shown in each region.
