First, the “tactile sample system” is defined. The category of the tactile sample system is "invention of things". The tactile sample system should at least include a plurality of tactile sample sheets with different tactile sensations, and may also include other incidental elements. In addition, it is sufficient that a plurality of tactile sample sheets in the tactile sample system can be grasped in a fixed unity. Therefore, for example, it is not limited to a mode in which a plurality of tactile sample sheets are connected and integrated, and even if a plurality of tactile sample sheets are independent, they are stored in containers such as bags and boxes. Alternatively, they may be separably coupled with a binding member such as a string or rubber. In this case, containers, binding members, and the like can also be components of the tactile sample system.

Next, each embodiment of the tactile sample system according to the present invention will be specifically described with reference to the drawings. As shown in FIG. 1, a tactile sample system 1A according to one embodiment includes a tactile sample book 2A. The tactile sample book 2A includes a plurality of tactile sample sheets 3A having different tactile sensations. The tactile sample book 2A includes a connecting portion 21 that supports a plurality of overlapping tactile sample sheets 3A. The connection part 21 is, for example, a shaft part penetrating through the plurality of tactile sample sheets 3A, and is treated for retaining. The plurality of tactile sample sheets 3A are each rotatable around the connecting portion 21 . A plurality of overlapping tactile sample sheets 3A can be integrated by the connecting portion 21, making it easy to handle.

The tactile sample sheet 3A according to the present embodiment has a rectangular shape, but the shape of the tactile sample sheet 3A is not limited to a rectangular shape, and may be other polygonal shapes, circular shapes, elliptical shapes, or the like. It may be irregularly shaped. Further, the tactile sample sheet 3A may be colorless or colored, and may have a pattern.

The tactile sample sheet 3A includes, for example, a substrate 32 and a printed portion 33 printed on the substrate 32 . The tactile sensation of the tactile sample sheet 3</b>A is adjusted by the ink applied to the printing portion 33 . For example, FIG. 2(a) is a cross-sectional view showing one example of a tactile sample sheet 3A out of a plurality of tactile sample sheets 3A, and FIG. 2(b) is a cross-sectional view of a plurality of tactile sample sheets 3A. It is sectional drawing which shows an example of 3 A of other tactile sample sheets of the inside. In addition, this embodiment is an example of a mode in which a tactile sensation is imparted and adjusted, and in addition to a form in which the printed portion 33 is formed by printing or coating as in this embodiment, physical processing is performed as described later. It may be an adjusted form, or an adjusted form by blending a plurality of polymers.

As shown in FIGS. 2(a) and 2(b), there are differences in shape (outer shape difference) such as differences in uneven shapes formed on the printed portion 33, differences in sizes, and differences in the density of convex portions. Different tactile sensations can be realized by Moreover, the difference in tactile sensation is not limited to the difference in external shape, and can also be realized by the difference in heat conduction (difference in thermophysical properties) caused by the difference in materials. The tactile sensation of the tactile sample sheet 3A will be described in more detail below.

A “tactile sensation” is a sensation (feeling) received by a person's hand, skin, or the like when touching an object. In addition, "different tactile sensations" generally means a mode having a difference that can be distinguished by human perception, and can be evaluated by human sensibility evaluation (sensory test).

For example, as a method of obtaining parameters for sensitivity evaluation, a normal sensitivity evaluation method can be used. As for subjective evaluation, there are psychophysical measurement methods that numerically correspond the amount of stimulus and sensation, and the scale construction method as a method of creating a standard (rule) for measuring subjective impressions. method can be used to evaluate the difference in tactile sensation.

It is also possible to quantify and define the tactile sensations of a plurality of tactile sample sheets 3A so as to be reproducible. For example, among psychophysical measurement methods and scaling methods, proportional scales, sensory scales, and rank scales can be treated as numerical values. Even if the direct tactile sensation cannot be quantified, it can be defined as an indirect tactile sensation using a nominal scale (for example, gender, residential area). Specifically, it is possible to distinguish and define the tactile sensation preferred by men, the tactile sensation preferred by women, or the tactile sensation preferred by each residential area.

Various proposals have been made for psychological scales used in scaling methods. For example, supervised by Hiromichi Hori (Professor Emeritus, Otsuma Women's University, University of Tsukuba), edited by Mariko Yamamoto (Former Professor, University of Tsukuba), "Psychological Scale Collection I-VI", published by Science Company, etc., there are many descriptions, these and Appropriate ones can be taken into account from the independently set scales.

Further, when it is necessary to associate and manage a plurality of tactile sample sheets 3A and digitized tactile sensations, the values are digitized and graphed, and the magnitude relationship is represented, for example, by the vertical axis. If many adjectives are written on the vertical axis to distinguish the degree of tactile sensation, management becomes complicated. Further, when the degree of tactile sensation is displayed by adjectives in association with the tactile sample sheet 3A, the display becomes difficult to read. Therefore, it is desirable to search for relationships between adjectives and onomatopoeias using psychostatistical methods, such as the semantic differential method (SD method), classify those with high correlations in an easy-to-understand manner, and display them as necessary.

In addition, for the tactile sensation of the tactile sample sheet 3A, each parameter such as rigidity, friction coefficient, microscopic surface roughness, macroscopic surface roughness, thermal sensation, etc. can be measured without performing sensibility evaluation. Therefore, the presence or absence of different tactile sensations can be quantitatively evaluated. A specific description will be given below.

[Regarding rigidity]
Rigidity can be evaluated based on JIS K7127, and different stiffness can be evaluated as different tactile sensations. For example, in the tactile sample sheet 3A made of plastic film, the tactile sample sheet (LLDPE) having a rigidity of approximately 400 MPa and the tactile sample sheet (laminated product) having a rigidity of approximately 2000 MPa have different tactile sensations.

[About friction coefficient]
The friction coefficient can be evaluated based on the JIS dynamic friction coefficient. Moreover, in order to evaluate the tactile sensation of the tactile sample sheet 3A, the evaluation can preferably be made from the viewpoint of the increase rate of the dynamic friction coefficient, which matches the tactile sensation of a human being. Specifically, the coefficient of dynamic friction is 0.1 to 0.7, and it can be evaluated in terms of the rate of increase in the coefficient of dynamic friction when the measurement speed is increased from 2 mm / s to 20 mm / s, for example, 10% or more. can be evaluated as favorable. The surface characteristic values of KES (Kawabata Evaluation System) used in the textile industry, the average friction coefficient of MIU, the variation of the average friction coefficient of MMD, and the average deviation of surface roughness of SMD can also be used.

[Microscopic surface roughness]
Micro surface roughness can be evaluated using ISO25178 surface texture parameters, but it is desirable to select an index that is linked to sensory evaluation. As an example, KEYENCE's homepage ("roughness" introduction.com), [searched on September 18, 2018], <https://www.keyence.co.jp/ss/3dprofiler/arasa/surface/parameters. jsp> can be referenced.

As described on the above website, the micro surface roughness is based on "height", Sa: arithmetic mean height, Sz: maximum height, Sq: root mean square height, Ssk: skewness degree), Sku: kurtosis (degree of sharpness), Sp: maximum peak height, and Sv: maximum valley depth. Also, based on the "space", evaluation can be performed using the parameters of Sal: minimum autocorrelation length and Str: aspect ratio of surface texture. Also, based on the "composite" evaluation, the evaluation can be performed using the parameters of Sdq: root-mean-square slope and Sdr: developed area ratio of the interface. In addition, based on "function", Smr(c): load area ratio, Smc(mr): reverse load area ratio, Sk: core level difference, Spk: height of protruding peak, Svk: height of protruding valley , Smr1: the load area ratio separating the protruding peak and the core, Smr2: the load area ratio separating the protruding valley and the core, and Sxp: pole height. Also, based on "function (volume)", evaluation is performed using each parameter: Vvv: Void volume in valleys, Vvc: Void volume in core parts, Vmp: Actual volume in peak parts, Vmc: Actual volume in core parts can do. Also, based on "morphology", Spd: peak density of peaks, Spc: arithmetic mean curvature of peak points, S10z: 10-point area height, S5p: 5-point peak area height, S5v: 5-point valley area depth, Sda(c): average valley area, Sha(c): average peak area, Sdv(c): average valley area volume, Shv(c): average peak area volume. can.

[Macro surface roughness]
Macroscopic surface roughness can be evaluated using, for example, the results of measurement with a needle-type surface roughness meter. In addition, the displacement can be measured while shifting the location using a three-dimensional measuring device, and the measurement results can be used for evaluation.

[Warmness]
Thermal sensation can be evaluated using the thermophysical properties of KES, which is used in the textile industry. For example, the heat flow peak value (Q max), which is the thermal sensation at the moment when the tactile sample sheet 3A is touched, can be evaluated as the tactile sensation. Moreover, the thermal conductivity (K), which is the thermal sensation in the state of continuously touching the tactile sample sheet 3A, can be evaluated as the tactile sensation.

In addition, KES is the website of Kato Tech Co., Ltd., [searched on September 18, 2018], "KES-F7 Thermolab" described in <http://www.keskato.co.jp/products/#panel07>, It can be measured using a device such as "FR07 Thermolab".

Also, the tactile sample sheet 3A can be adjusted to have different tactile sensations depending on the manufacturing method. In this case, it is possible to indirectly specify that different tactile sensations are realized by specifying the manufacturing method and manufacturing conditions without evaluating the above parameters and human sensibility. Hereinafter, the method for manufacturing the tactile sample sheet 3A adjusted to the desired tactile sensation, and the tactile sample sheet 3A will be described.

First, the tactile sample sheet 3A adjusted to have a desired tactile feel by the ink applied to the printing unit 33 will be described. The tactile sample sheet 3A includes a sheet-like base material 32 and a printed portion 33 printed on the base material 32 . By adjusting the tactile sensation with the ink applied to the printing portion 33, it is possible to easily realize the tactile sample sheet 3A having various tactile sensations. Note that the ink includes a coating agent as well as general ink containing pigments and the like.

As the substrate 32, for example, a resin film can be used. Various synthetic resin sheets such as polyethylene, polypropylene, ethylene-propylene copolymer, polyester, polyacryl, polyamide, polyurethane, and polystyrene can be used as the resin film.

The printed portion 33 is formed by applying ink to the surface of the base material 32 . As a method of applying ink (coating method), for example, the method described in Japanese Patent No. 4482803 can be used. Ink application methods include printing, flexographic printing, screen printing, gravure coater, gravure reverse coater, flexo coater, blanket coater, roll coater, knife coater, air knife coater, kiss touch coater, and kiss touch reverse. Coating methods such as coater and comma coater, comma reverse coater, and micro gravure coater can be used.

Further, as a coating method (method for forming the printed portion 33) for adjusting the tactile sensation, the method described in Japanese Patent Application Laid-Open No. 2015-180711 can be used. FIG. 3(a) is a cross-sectional view showing an aspect in which the printing portion 33 is formed by this method. In this method, after forming an intermediate layer made of texture ink containing polysiloxane on the upper surface of the undercoat layer of the base material 32, by forming a topcoat, the intermediate coating film 33a and the topcoat coating film 33b are integrated to form a design. Concavo-convex shape can be easily formed. According to this method, it becomes easier to adjust so as to obtain a desired and appropriate tactile sensation.

In addition, the tactile sensation can be adjusted by coating the surface of the base material 32 . Examples of the coating method include roll coating, die coating, spin coating, lip coating, comma coating, bar coating, dip coating, casting film formation, and gravure coating. can be done. It is also possible to apply ink on the base material 32 by these methods and dry or cure the ink to adjust the desired tactile feel.

As the above ink, thermosetting ink, solvent type (toluene) ink, solvent type (non-toluene) ink, water-soluble ink, etc. can be used. A UV type (ultraviolet curing type) coating varnish may be used as the ink.

The tactile sensation can also be adjusted by applying an ink containing a filler. In this case, inorganic fillers, inorganic beads, polymer fillers, polymer beads and the like can be used as fillers.

Next, a tactile sample sheet whose tactile sensation is adjusted without providing the printing unit 33 will be described. For example, as shown in FIG. 3B, in a tactile sample sheet 3A according to the first modification, an adhesive is applied on a base material 32 to form an adhesive layer 34, and the adhesive layer 34 is It is a tactile sample sheet 3A coated with granules 35 thereon, and the desired tactile sensation is adjusted by the application of the granules 35 . Further, for example, as shown in FIG. 3C, in a tactile sample sheet 3A according to the second modification, a double-sided tape 36 is attached on the base material 32, and the side opposite to the base material 32 is attached. It is a tactile sample sheet 3A in which granules 35 are applied to the other surface, and the desired tactile sensation is adjusted by the application of the granules 35. - 特許庁Granular materials include fine powders, and inorganic fillers, inorganic beads, polymer fillers, polymer beads and the like can be used.

As another form in which the printing unit 33 is not provided, for example, a tactile sample sheet whose tactile sensation is adjusted by physical processing can be used. As physical processing, for example, the tactile sensation is adjusted by applying pressure to the base material with a press to deform it, the tactile sensation is adjusted by roughening the surface of the base material with sandpaper, etc., and the base material is heated. The tactile sensation can be adjusted by deforming the base material using a mold or the like in that state. Also, as physical processing, for example, a laser plate or an engraving plate can be used. Moreover, the surface treatment of a base material can also be performed as a physical process. For example, the tactile sensation can be adjusted by a surface treatment method using corona discharge, a flame method (roughening the surface with a flame), a laser method, or the like.

Further, as a tactile sample sheet whose tactile sensation is adjusted by physical processing, for example, a tactile sample sheet whose surface is provided with an uneven pattern by an embossing roll or the like at the time of manufacturing the base material can be used. In addition, by using a forming method (see JP-A-2002-144485) in which a decorative sheet having an uneven pattern is attached to a base material, a decorative sheet having fine unevenness is attached to a base material to form a tactile sample sheet. You can also

As another form in which the printed part 33 is not provided, for example, a tactile sample sheet in which the tactile sensation is adjusted by blending two or more types of polymers (polymer blend) at the time of manufacturing the base material can be used. Alternatively, instead of the printed portion 33, a tactile sample sheet having a tactile sensation may be prepared by bonding a film having a tactile sensation to a substrate.

Next, the light transmittance of the tactile sample sheet 3A will be described. By light transmissive is meant transparent or translucent. More specifically, the presence or absence of light transmittance can be quantitatively evaluated by "haze". For example, according to the tactile sample sheet 3A with a "cloudiness (haze)" of 85% or less based on "Plastics - How to determine the haze of transparent materials (JIS K 7136)" At the time of matching, it is possible to confirm the pattern, etc. of the printed matter of the object. That is, in the present embodiment, having light transmittance means having a "haze" of 85% or less. Further, if the "haze" is 10% or less, the haze is about the same as that of a general transparent film, and it is desirable that the pattern and the like can be clearly grasped. Further, the tactile sample sheet 3A may be colored, but it is desirable if it is colorless, because not only the pattern of the object but also the color and texture can be grasped.

Note that the tactile sample sheet 3A according to the present embodiment has light transmittance, but does not have light transmittance, and has a "haze" greater than 85%. It can also be made into a form having properties.

Next, the breakage guide structure 37 (see FIG. 1) provided on the tactile sample sheet 3A will be described. The tactile sample sheet 3A is provided with a breakage guide structure 37 that guides breakage into a plurality of sample pieces 31A. The fracture induction structure 37 is a structure intentionally formed to trigger cutting along a certain direction (anticipated cutting line) when receiving a shearing force. The breakage guide structure 37 may be, for example, a perforation along the planned cutting line, or a structure in which the thickness of the linear portion along the planned cutting line is thinner than the other portions.

The tactile sample system 1A according to the present embodiment may further include a texture sample book 4A (see FIG. 4) in addition to the tactile sample book 2A. The texture sample book 4A is housed in a set with the tactile sample book 2A, for example, during transport or storage. The texture sample book 4A comprises a plurality of texture sample sheets 5A. The texture sample sheet 5A is a sample imitating an actual printed matter or the like of an assumed product or the like. The texture sample sheet 5A is an example of a texture sample. The texture sample is not limited to a two-dimensional sheet, and may be a three-dimensional structure.

The plurality of texture sample sheets 5A differ in at least one of color, pattern and texture. The difference in color means that at least one of hue, saturation, and lightness is different, and the presence or absence of color difference in relation to the pattern can be evaluated in a composite manner. Moreover, the texture means the visual characteristics and form of the material, and includes a form that imitates the texture of a given material. The color, pattern or texture of the texture sample sheet 5A may be different from the color, pattern or texture of the tactile sample sheet 3A, or may be common.

The texture swatch book 4A includes a connecting portion 41 that supports a plurality of overlapping texture swatch sheets 5A. The connecting portion 41 is, for example, a shaft portion penetrating through the plurality of texture sample sheets 5A, and is treated for retaining. The plurality of texture sample sheets 5A are each rotatable around the connecting portion 41. As shown in FIG. A plurality of overlapping texture sample sheets 5A can be integrated by the connecting portion 41, which facilitates handling.

The texture sample sheet 5A according to the present embodiment has a rectangular shape, but the shape of the texture sample sheet 5A is not limited to a rectangular shape, and may be other polygonal shapes, circular shapes, elliptical shapes, or the like. It may be irregularly shaped.

The texture sample sheet 5A has a break guide structure 57 that guides breakage into a plurality of sample pieces 51 . The fracture induction structure 57 is a structure intentionally formed to trigger cutting along a certain direction (anticipated cutting line) when receiving a shearing force. The breakage guide structure 57 may be, for example, a perforation along the planned cutting line, or a structure in which the thickness of the straight portion along the planned cutting line is formed thinner than the other portions.

Next, a tactile sensation evaluation method for confirming tactile sensation using the tactile sensation sample system 1A according to the present embodiment will be described. The tactile sample system 1A includes a tactile sample book 2A and a texture sample book 4A. An evaluator (human) selects one or a plurality of texture sample sheets 5A corresponding to an assumed object such as a product from among the plurality of texture sample sheets 5A in the texture sample book 4A. Next, the evaluator puts each of the plurality of tactile sample sheets 3A in the tactile sample book 2A on the selected texture sample sheet 5A, confirms the tactile sensation of the tactile sample sheet 3A in this state, and confirms the tactile sensation of the texture sample sheet 5A. Evaluate suitable tactile sensations.

As a supplement, the evaluator superimposed each of the plurality of tactile sample sheets 3A of the tactile sample book 2A on the object (see the object 100 in FIG. 7 as an example) without using the texture sample book 4A, and in this state It is also possible to check the tactile sensation of the tactile sample sheet 3A and evaluate the tactile sensation suitable for the object.

Here, "evaluating the tactile sensation suitable for the object (texture sample sheet)" means, for example, performing sensibility evaluation with the tactile sensation sample sheet superimposed on the object, and selecting a suitable tactile sensation sample sheet from among a plurality of tactile sensation sample sheets. This includes a wide range of cases, such as selecting a tactile sample sheet and specifying a tendency of a tactile sense that is compatible with an object while using a plurality of tactile sample sheets. More specifically, the evaluator checks the tactile sensation of the tactile sample sheet 3A against the texture sample sheet 5A by touching it with a finger or the skin, and comprehensively evaluates hardness, softness, comfort, etc., based on compatibility. It is possible to evaluate the tactile sensation suitable for the texture sample sheet 5A. In addition, the evaluator can also perform this evaluation, for example, according to the above-described Kansei evaluation method.

Further, the term "object" broadly includes samples and models imagining products, etc., and may be a shape imitating the shape of a finished product as it is, or a part of the shape. In addition, "products, etc." are not limited to products to be traded, but include a wide range of tangible objects used only within the company and prototypes in the development stage.

According to the tactile evaluation method using the tactile sample system 1A according to the present embodiment, it is possible to confirm the tactile sense of the tactile sample sheet 3A corresponding to the target object (including the texture sample sheet 5A). As a result, the tactile sensation suitable for the object can be evaluated.

In particular, the present embodiment is a tactile sensation evaluation method using the tactile sample sheet 3A, and the tactile sample sheet 3A can be evaluated with a tactile sensation suitable for a product or the like while comparing tactile sensations such as touch. It is possible to evaluate the tactile sensation suitable for products, etc. Therefore, it is advantageous in providing comfortable products and environments for the visually impaired.

Further, the tactile sample sheet 3A according to the present embodiment has optical transparency. Therefore, when the tactile sample sheet 3A is overlaid on the texture sample sheet 5A, the colors and patterns of the texture sample sheet 5A can be seen through. As a result, according to the tactile sample system 1A according to the present embodiment, not only the tactile sense of the tactile sample sheet 3A but also the complex evaluation including the color of the transparent texture sample sheet 5A, that is, the color and tactile A composite evaluation of

Further, the tactile sample sheet 3A is provided with a rupture-inducing structure 37, and the texture sample sheet 5A is provided with a rupture-inducing structure 57. As shown in FIG. The tactile sample sheet 3A can be divided along the breakage guide structure 37, and by this division, one or more sample pieces 31A (tactile sample pieces) can be separated. Moreover, the texture sample sheet 5A can be divided along the fracture guide structure 57, and by this division, one or more sample pieces 51 (texture sample pieces) can be separated. As a result, the tactile sensation can be confirmed while overlapping the tactile sample piece 31A on the object or the texture sample piece 51, and the tactile sensation suitable for the object or the texture sample piece 51 can be evaluated (see FIG. 5). In particular, since the tactile sample piece 31A has translucency, it is possible to evaluate the tactile sensation while confirming the color of the object or the like in a state of being superimposed on the object or the texture sample piece 51. .

Next, a tactile sample system 1B according to another embodiment will be described with reference to FIGS. 6 and 7. FIG. The tactile sample system 1B includes a tactile sample book (not shown) having a plurality of tactile sample sheets 3B. The tactile sample sheet 3B has the same structure as the tactile sample sheet 3A according to the above-described embodiment, includes a substrate 32 and a printed portion 33 printed on the substrate 32, and has optical transparency. Further, the tactile sample sheet 3B may have a structure in which a desired tactile sensation is realized by various methods without providing the printing unit 33, as described above.

A release paper 39 is adhered via an adhesive layer 38 to the base material of the tactile sample sheet 3B. The release paper 39 is provided on the side opposite to the printed portion 33 where the tactile sensation is adjusted. The release paper 39 has a function of protecting the adhesive layer 38 and can be peeled off from the substrate 32 . The tactile sample sheet 3B is provided with a breaking guide structure 37, and the tactile sample sheet 3B can be divided into a plurality of sample pieces 31B.

Next, a tactile sensation evaluation method for confirming tactile sensation using the tactile sensation sample system 1B according to the present embodiment will be described. The tactile sample system 1B includes a plurality of tactile sample sheets 3B. When using the tactile sample sheets 3B, the evaluator peels off the release paper 39 while appropriately separating the sample pieces 31B from each of the plurality of tactile sample sheets 3B. Next, the evaluator adheres each of the sample pieces 31B so as to overlap the object 100, confirms the tactile sensation of the sample piece 31B in the state of being overlapped with the object 100, Evaluate tactile sensation. In addition, since the sample piece 31B is light transmissive, when the sample piece 31B is superimposed on the object 100, the color of the printed matter of the object 100 can be seen through.
