(Embodiment 1)
FIG. 1 is a cross-sectional view of a floor sheet 1 in the present embodiment.

  The floor sheet 1 includes a coloring layer 101 and a protective layer 102. The coloring layer 101 includes a structural color layer 1011 and a functional dye layer 1012. The protective layer 102 includes a first protective layer 1021 and a second protective layer 1022. The first protective layer 1021 includes a first cushion layer 1021a and a first surface protective layer 1021b, and the second protective layer 1022 includes a second cushion layer 1022a and a second surface protective layer. Layer 1022b.

  In the floor sheet 1, a second protective layer 1022, a coloring layer 101, and a first protective layer 1021 are laminated from the bottom to the top. In the color developing layer 101, a functional dye layer 1012 is laminated on the structural color layer 1011. In the first protective layer 1021, the first surface protective layer 1021b is laminated on the first cushion layer 1021a. In the second protective layer 1022, the second cushion layer 1022a is laminated on the second surface protective layer 1022b. Each of the above layers may be adhered with, for example, an adhesive material having adhesiveness, or may be adhered with an adhesive or the like. The width and length of the floor sheet 1 are not limited.

  The floor sheet 1 is a sheet disposed on the floor. The place where the floor sheet 1 is disposed does not matter. The place where the floor sheet 1 is disposed is, for example, a park, a jogging course, an underpass, a hospital, a rehabilitation facility, a general house where home medical care is performed, and the like. When the floor sheet 1 is disposed outdoors, the floor on which the floor sheet 1 is disposed may be the ground or a road.

  The color development layer 101 is a layer that performs color development of different hues in response to input received from one or more users located on the floor sheet 1. The input received from the user is, for example, a force, pressure, friction, light, temperature, sound, biological signal, or the like received from the user. The input received from the user is, for example, an input of force received from the user. It may be considered that the development of a different hue according to the input of the force received from the user is the development of a different hue according to the force received from the user. The force received from the user is, for example, a force that presses the coloring layer 101 received from the user. For example, when the user is on the floor sheet 1 or moves on the floor sheet 1, this is the force that the coloring layer 101 receives from the user. Here, the coloring layer 101 receives a pressing force indirectly from the user via the second protective layer 1022, but when the second protective layer 1022 is not provided, the coloring layer 101 is pressed directly from the user. You may receive power.

  Color development with different hues is color development with at least different hues. For example, color development with a constant hue value and different combinations of lightness and saturation is color development with the same hue. For example, white and red are different in lightness and saturation, but have the same hue, and therefore are considered to have the same hue. Color development of different hues may be different in color development. Examples of color development include a color development pattern and a color development range. Color development of different hues includes color development by a combination of a plurality of different hues. Coloring may be accompanied by light emission or may not be accompanied by light emission.

  The development of a different hue according to the received force may be, for example, the development of a different hue according to the strength of the received different force, or a color forming layer that is deformed by the received force. Depending on the shape of 101, the amount of deformation, for example, the depth of depression, the width of depression, etc., different hues may be developed.

  For example, the color developing layer 101 normally performs color development of different hues at a position corresponding to the received force. For example, the color developing layer 101 performs color development of different hues at and around the position where the force is received. For example, different hues are developed around the position where the force is received. The range in which the coloring layer 101 develops color does not matter. For example, the color developing layer 101 performs color development with different hues only in a partial region of the floor sheet 1. For example, the color developing layer 101 performs color development of different hues within a range of the width according to the received force. However, the coloring layer 101 as a whole may be colored in different hues according to the received force.

  For example, the color forming layer 101 may perform color development of different hues continuously or may perform color development of different hues step by step according to the received force.

  For example, the color forming layer 101 is formed of one or more layers having a property of performing color development with different hues according to the force received from the outside, and thereby develops colors with different hues according to the received power. The coloring layer 101 is, for example, a layer having one or more structural color layers 1011. The color forming layer 101 may further have one or more functional dye layers 1012 above or below the structural color layer 1011. Further, the color forming layer 101 may be a layer composed of only one or more structural color layers 1011, for example. Hereinafter, in this embodiment, the case where the color forming layer 101 is configured by the structural color layer 1011 and the functional dye layer 1012 to perform color development of different hues according to the force received from the outside is given as an example. Explains.

  The structural color layer 1011 is a layer whose structural color changes due to deformation. The structural color layer 1011 is a layer having transparency. The structural color is, for example, a coloring phenomenon due to a fine structure having a wavelength of light or less. The color of the structural color layer 1011 is, for example, reflected light on the surface of the structural color layer 1011, reflected from the surface through the structural color layer 1011 and reflected from the lower surface side, and again transmitted through the structural color layer 1011. It is a color that can be seen by interference with light output from the surface. For example, when a force is applied to the structural color layer 1011, the shape of the portion to which the force of the structural color layer 1011 is applied is deformed according to the force, and the moving distance of the light transmitted through the deformed portion is changed. The wavelength of the interfering light also changes, and as a result, the color is developed with a different hue depending on the applied force. For this reason, the structural color layer 1011 develops colors with different hues according to the force received directly or indirectly from the user.

  The structural color layer 1011 is preferably an elastic layer. Since the structural color layer 1011 has elasticity, even if the structural color layer 1011 deforms according to the force received from the user and develops a structural color having a hue different from that before the deformation, the force is applied thereafter. Otherwise, the original state is restored, and the structural color layer 1011 is colored with the structural color before deformation. By changing the elastic modulus by changing the material or the like of the structural color layer 1011, it is possible to adjust the time from the deformed state due to the force received from the user to return to the original state, and the color development by the structural color layer 1011 changes. The time to do can be adjusted. However, when it is desired to maintain the color after deformation, a layer having plasticity may be used as the structural color layer 1011.

  Since the structural color layer 1011 is colored with different colors according to the deformation caused by the force received from the user, the color development with different colors usually occurs locally at the portion where the force is received from the user or in the vicinity thereof.

  As the structural color layer 1011, for example, a layer formed of an elastic body disclosed in Patent Document 2 described below can be used. “Patent Document 2: Japanese Patent Laid-Open No. 2006-28202 (first page, FIG. 1 etc.)”.

  The thickness of the structural color layer 1011 is not limited. The thickness is determined according to, for example, the structural color emitted by the structural color layer 1011 in a state where no force is applied, the ease of walking of the floor sheet 1, and the like.

  Note that, here, the structural color layer 1011 is illustrated as an example of a single layer, but the structural color layer 1011 may be formed by stacking a plurality of layers. In this case, each layer to be laminated is preferably a structural color layer made of a different material.

  The functional dye layer 1012 is a layer whose hue is reversibly changed by an external stimulus, that is, a layer whose hue is reversibly changed. For example, the functional dye layer 1012 is a layer in which a hue that develops color changes when force or heat is applied. The functional dye layer 1012 is a layer having transparency.

  For example, the functional dye layer 1012 is a layer made of a so-called mechanochromic material. A layer composed of a mechanochromic material may be considered as a layer having a mechanochromic material. The mechanochromic material is a material whose hue changes in accordance with an external force, and the functional dye layer 1012 becomes a layer whose hue changes by an external force by the mechanochromic material. As the functional dye layer 1012, for example, it is preferable to use a mechanochromic material whose hue change is reversible. As the mechanochromic material, for example, a mechanochromic material described in Japanese Patent Application Laid-Open No. 2014-58606, Japanese Patent Application Laid-Open No. 2012-158678, or the like can be used. For example, as a mechanochromic material, for example, a compound having a diarylbibenzofuranone structure, such as a diarylbibenzofuranone diol, a diarylbibenzofuranone polyester, a diarylbibenzofuranone polyurethane, an aryl gold isocyanide complex, or the like can be used. . The layer composed of a mechanochromic material may be considered as a layer having a mechanochromic molecule or a layer having a mechanochromic material. For example, a layer formed by molding a resin containing a mechanochromic material may be used.

  For example, since the functional dye layer 1012 is made of a mechanochromic material, the hue of the functional dye layer 1012 is changed by the force of pressing the floor sheet 1 by the user on the floor sheet 1. The color formed by combining the hue of the coloring layer 1012, and the hue of the structural color layer 1011 is developed as the color of the coloring layer 101. Compared with the case where the dye layer 1012 is not provided, it is possible to change greatly.

  For example, the functional dye layer 1012 may be a layer made of a so-called thermochromic material. The thermochromic material is a material whose hue changes due to heat from the outside. By including the thermochromic material, the functional dye layer 1012 becomes a layer whose hue changes due to heat from the outside. As the thermochromic material, for example, a thermochromic material described in Japanese Patent Application Laid-Open No. 2004-346261, Japanese Patent Application Laid-Open No. 07-103829, or the like can be used. As the thermochromic material, for example, copper N, N-diethylethylenediamine complex, mixed lanthanide / triphenylphosphine oxide complex, mercury iodide complex salt compound, cholesterol acetate, photomerocyanine and the like can be used. For example, by using a mixed lanthanide / triphenylphosphine oxide complex having 99% terbium emitting green light and 1% europium emitting red light, the hue of light emission can be changed depending on the temperature. The layer composed of the thermochromic material may be considered as a layer having a thermochromic molecule or a layer having a thermochromic material. For example, it may be a layer obtained by molding a resin containing a thermochromic material. The same applies to the following thermochromic materials.

  For example, when the functional pigment layer 1012 has a thermochromic material, heat generated by the user on the floor sheet 1, for example, heat caused by the user's body temperature transmitted from the user, Heat generated by performing dynamic motion or the like, for example, frictional heat, is transmitted to the functional dye layer 1012 to change the hue of the functional dye layer, and the hue of the functional dye layer 1012 Since the color combined with the hue of the structural color layer 1011 is developed as the color of the color developing layer 101, the color generated by the color developing layer 101 can be changed by heat caused by the user. .

  Note that the functional dye layer 1012 may include both a mechanochromic material and a thermochromic material. Regarding the chromic material, please refer to the following Non-Patent Document 1 (Non-Patent Document 1: J. Sonnenberg, 1 other name, “Oxidation of Triarylidazoles. Structure of the Photochromic and Piezochromic”. Am. Chem. Soc., 1966, 88 (16), pp. 3825-3829).

  The functional dye layer 1012 may be a layer having a phosphorescent substance. A phosphorescent substance is a substance that emits excitation light and has a property that light emission continues even after the excitation light disappears. A phosphorescent substance is also called a phosphorescent substance. For example, the phosphor is zinc sulfide, strontium aluminate, salen-type platinum complex, or the like. By including the phosphorescent material, the functional dye layer 1012 can emit light even in a place where illumination or light is extinguished. For example, since the functional dye layer 1012 has a phosphorescent substance, the floor sheet 1 can emit light even in a place where illumination is turned off, and the color of the functional dye layer 1012 and the color of the structural color layer 1011 As a color of the coloring layer 101, the color of the light emitted from the portion that has received a force from the user can be changed to a different hue according to the force.

Note that the functional dye layer 1012 may include a plurality of phosphorescent stones having a phosphorescent material and colored in a plurality of different colors. Phosphorescent stones are artificial stones made using phosphorescent materials. Phosphorescent stone absorbs light energy and gradually emits light at night and when extinguished. For example, phosphorescent stones emit light of a colored color. For example, the phosphorescent stone is produced, for example, by polymerizing and curing a phosphorescent material with an acrylic resin. There is no limitation on the size of the phosphorescent stone. Regarding the phosphor, refer to the following Non-Patent Document 2 (Non-Patent Document 2: “Fabrication of Eu: SrAl ₂ O ₄ -based glass ceramics using Frozen Sorbet method”, Journal of the Ceramic Society 20). , Vol. 119 [7], pp. 609-615)

  Note that the functional dye layer 1012 may include two or more of mechanochromic molecules, thermochromic molecules, and phosphorescent substances.

  The functional dye layer 1012 is preferably a layer having elasticity, for example. However, the functional dye layer 1012 may be a layer having plasticity or a layer not having elasticity.

  In the present embodiment, the hue obtained by combining the coloring of the functional dye layer 1012 and the coloring of the structural color layer 1011 is the hue that the coloring layer 101 develops according to the force from the user. For this reason, even if the color change of the functional dye layer 1012 is a color change with the same hue, the color is generated with a different hue depending on the force applied by the structural color layer 1011. As a result, the layer 101 becomes a layer that develops colors with different hues depending on the applied force.

  The thickness of the functional dye layer 1012 is not limited. The thickness of the functional dye layer 1012 is determined, for example, according to the ease of walking of the floor sheet 1, the color density of the functional dye layer 1012, and the like. The thickness of the functional dye layer 1012 is preferably a thickness that prevents the structural color layer 1011 disposed below from being visible. Further, the thickness is preferably such that the force applied to the functional hue layer 1012 is transmitted to the structural color layer 1011. The thickness of the functional dye layer 1012 is, for example, 1 μm to 10 μm. However, the thickness can be changed as appropriate according to the material and transmittance of the functional dye layer 1012.

  Of the materials used for the functional dye layer 1012, a mechanochromic material such as a mechanochromic molecule, a thermochromic material such as a thermochromic molecule, or a material excluding a phosphorescent material, the functional dye layer 1012 has transparency. Any material may be used as long as it is a material to be included.

  The transmittance of the functional dye layer 1012 is preferably as high as possible. The transmittance of the functional dye layer 101 is preferably such that it can clearly recognize the hue of the structural color layer 1011 as a lower layer, for example, 50% or more.

  Note that, here, a case where one functional dye layer 1012 is provided is shown as an example, but the color forming layer 101 may include a plurality of different functional dye layers 1012 stacked. good. The different functional dye layers 1012 are, for example, a combination of a functional dye layer that develops a different hue, a functional dye layer that includes a phosphorescent substance, and a functional dye layer that does not include a phosphorescent substance. May be.

  For example, the coloring layer 101 may have a layer in which a plurality of functional dye layers 1012 having different temperatures and / or forces at which a hue change occurs are laminated. In addition, the plurality of functional dye layers 1012 stacked in this case are preferably layers having different hues for color development. The hue to be developed here may be the hue before the change, the hue after the change, or both.

  The protective layer 102 is a layer for protecting the coloring layer 101. Here, as the protective layer 102, a first protective layer 1021 is provided on the upper surface side of the coloring layer 101, and a second protective layer 1022 is provided on the lower surface side of the coloring layer 101. However, only one of the first protective layer 1021 and the second protective layer 1022 may be provided.

  The first protective layer 1021, specifically, the first cushion layer 1021a and the first surface protective layer 1021b constituting the first protective layer 1021 are made of a material that is transmissive to visible light. It is preferable that the material is transparent or nearly transparent. In addition, the color of the first protective layer 1021 is preferably a color that does not interfere with color development by different hues by the color development layer 101, and is colorless or nearly colorless, white or near white, etc. It is preferable.

  The material of the first cushion layer 1021a is preferably an elastic material. By changing the elastic modulus of the first protective layer 1021, the deformation amount of the coloring layer 101 with respect to the force applied to the surface of the floor sheet 1 can be adjusted, and the change in coloring of the coloring layer 101 can be adjusted. Can do. In addition, by changing the material of the first cushion layer 1021a to a low resilience material having a slow recovery speed and adjusting the speed of the recovery, the first cushion layer 1021a is colored via the first cushion layer 1021a. The rate at which the force applied to the layer 101 decays can be adjusted, and the time during which the color change of the color forming layer 101 lasts can be adjusted.

  The first cushion layer 1021a is a sheet of polyurethane, silicone gel, rubber, or the like, for example. The thickness of the first cushion layer 1021a is not limited.

  The first surface protective layer 1021b is a layer for protecting the first cushion layer 1021a and the coloring layer 101. The first surface protective layer 1021b is preferably made of a material excellent in corrosion resistance, impact resistance, water resistance, antifouling property, and scratch resistance. The first surface protective layer 1021b may be a film for surface protection or the like, and may be considered as a coating for surface protection. In addition, since it is necessary to locally transmit the force applied to the surface to the coloring layer 101 in the vicinity of the region where the force is applied, the material of the first surface protective layer 1021b is preferably a flexible material. .

  As the first surface protective layer 1021b, for example, a polyester film such as polyethylene terephthalate, polybutylene terephthalate, or polyethylene naphthalate, a polyolefin film such as polypropylene or polyethylene, or the like can be used. There is no limitation on the thickness or the like of the first surface protective layer 1021b. The thickness of the first surface protective layer 1021b is preferably a thickness that does not break when the user steps on the foot or the like. Moreover, it is preferable that the thickness of the first surface protective layer 1021b is, for example, a thickness that is easily deformed by a force from the user. For example, the thickness of the first surface protective layer 1021b is preferably, for example, 50 μm to 250 μm. The thickness of the first surface protective layer 1021b is determined according to the material of the first surface protective layer 1021b, for example. In addition, when a layer (not shown) composed of an adhesive used for adhesion or adhesion to the color forming layer 101, an adhesive, or the like is sufficiently soft, the thickness of the first surface protective layer 1021b is as described above. Even if it is thicker than the preferred range, sufficient force may be transmitted to the coloring layer 101.

  As the material of the second cushion layer 1022a, the material described in the first cushion layer 1021a can be used, and detailed description thereof is omitted here. The thickness of the second cushion layer 1022a may be the same as or different from the thickness of the first cushion layer 1021a. However, the first cushion layer 1021a does not need to transmit visible light, and thus may not have transparency. Further, the color of the first cushion layer 1021a is not limited.

  As the material of the second surface protective layer 1022b, the same material as that of the first surface protective layer 1021b as described above can be used. However, since the second surface protective layer 1022b is disposed on the lowermost surface of the floor sheet 1, the thickness thereof may be sufficiently hotter than that of the first surface protective layer 1021b. In addition, since it is not necessary to locally transmit the force applied to the surface to the vicinity of the region where the force is applied, materials other than those described above can be used. Further, since the second surface protective layer 1022b does not need to transmit visible light, it may not have transparency. Further, the color of the second surface protective layer 1022b is not limited. For example, as the second surface protective layer 1022b, for example, a metal plate, a resin plate, or the like can be used. The second protective layer 102 may be an opaque material or a transparent material. For example, a layer that reflects light, such as an aluminum foil, may be provided on the surface side of the second protective layer 1022b, or the surface side may be coated with a material that reflects light. By setting it as such a structure, the hue which changed in the coloring layer 101 can be shown more strongly and can be shown on the surface side of the sheet | seat 1 for floors. In addition, when the second protective layer 102 is made of a transparent material, for example, when the floor sheet 1 is used on a floor that can be viewed from the lower surface side, a change in hue is also observed on the lower surface side. Can do.

  Note that the first protective layer 1021 and the second protective layer 1022 may be omitted as appropriate if protection of the coloring layer 101 and adjustment of coloring are unnecessary. Similarly, in the first protective layer 1021, the first cushion layer 1021a and the first surface protective layer 1021b may be omitted as appropriate. Similarly, in the second surface protective layer 1022b, the second cushion layer 1022a and the second surface protective layer 1022b may be omitted as appropriate. For example, when a material having low resilience is used as the material of the coloring layer 101, the first cushion layer 1021a and the like may be omitted.

  Hereinafter, the operation of the floor sheet 1 will be described using a specific example. Here, the functional dye layer 1012 has mechanochromic molecules, thermochromic molecules, and a phosphorescent substance.

FIG. 2B is a schematic cross-sectional view (FIG. 2B), and a schematic cross-sectional view of the floor sheet 1 in a state where the user B is stepping on the floor (FIG. 2C). 2 (b) and 2 (c) are schematic diagrams for explanation, and the relationship between the size of the user's foot and the thickness of the floor sheet 1 in the figure is the actual foot. The relationship between the thickness of the floor sheet 1 and the like is not necessarily the same.

The vicinity of the portion of the floor sheet 1 that is stepped on by the user's foot is recessed by the user's pressing force on the floor sheet 1. Accordingly, the thickness d ₁₁ of the structural color layer 1011 of the portion 21 which is stepped by foot is thinner than the thickness d ₂₁ of the portion not stepped on by a foot. As a result, the wavelength of light emphasized in the structural color layer 1011 changes, and the structural color of the portion 21 stepped on by the foot of the structural color layer 1011 and the structural color of the portion not stepped on by the foot are different. It becomes a hue. Further, since the color of the functional dye layer 1012 changes depending on the user's pressing force on the floor sheet 1, the functional dye layer 1012 has a different hue between the stepped part and the non-stepped part. Color will develop. Thereby, the part 21 stepped on with the foot | leg of the floor sheet 1 will color with a hue different from the part which is not stepped on.

Further, if a user B having a weight different from that of the user A is walking on the floor sheet 1, the thickness of the structural color layer 1011 of the portion stepped on with the foot changes as described above, The color will be developed with a different hue from the unstepped part. At this time, the force with which the user A presses the floor sheet 1 and the force with which the user B presses the floor sheet 1 differ depending on the difference in the weight of the user, the way the user applies the force when walking, etc. and to become, the thickness _{d 31} of the portion 31 which is stepped to user B, thickness different from the thickness _{d 21} of the portion 21 which is stepped to the user a _(e.g., d 31 _{<d 21)} When was the The portion 21 stepped on by the user A and the portion 31 stepped on by the user B are colored with different hues. As a result, the portion 21 stepped on by the user A and the portion 31 stepped on by the user B are colored with different hues. Further, since the force applied to the functional dye layer 1012 is also different, the density at which the functional dye layer 1012 develops is different. As a result, the floor sheet 1 receives a pressing force that varies depending on the weight of each user, how to walk, etc., from each user walking on the surface, and the position where each user has walked according to the difference in force. In this case, the color is developed with different hues.

  Further, for example, if the user A walks while rubbing his / her foot on the floor sheet 1, the frictional heat generated by the rubbed foot is caused by the functional pigment layer of the color developing layer 101 via the first protective layer 1021. The functional dye layer 1012 having a thermochromic molecule is colored with a hue different from that when there is no heat. As a result, the portion of the floor sheet 1 where the feet are rubbed is colored with a hue different from that in a normal way of walking.

  In addition, when a user walks, once the color is developed, energy having a wavelength corresponding to the color of the developed light is added to the phosphor, and electrons move in the phosphor to be in a triplet state. Then, at night or when the lighting is turned off, the phosphorescent material emits phosphorescence when returning from the triplet state to the ground state. By this phosphorescence emission, after the user finishes walking, the footprint the user has walked can be emitted.

  As described above, according to the present embodiment, the floor sheet can be colored with a hue corresponding to the force applied by the user, and the floor can be dynamically decorated according to the input of the force from the user. .

  In this embodiment, when the coloring layer 101 of the floor sheet 1 is the structural color layer 1011 or when the coloring layer 101 has the structural color layer 1011 and the functional dye layer 1012. In the present invention, the color forming layer 101 may be composed of one or more functional dye layers 1012. In such a case, for example, the coloring layer 101 can be colored with different hues according to inputs such as friction and temperature received from the user.

(Embodiment 2)
In the above embodiment, a case has been described in which the coloring layer develops a color with a different hue according to the input of force, but in this embodiment, the coloring layer has a different hue according to the input of a signal from the user. The case of color development will be described.

  FIG. 3 is a view for explaining the floor sheet 2 in the present embodiment.

  The floor sheet 2 includes a reception unit 201, a storage unit 202, a storage unit 203, a recognition unit 204, a determination unit 205, an output unit 206, and a sheet-like unit 20. The sheet-like portion 20 includes a coloring layer 207, a sound output layer 208, and a protective layer 209. The protective layer 209 includes a first protective layer 2091 and a second protective layer 2092.

  The mobile terminal device 3 is a mobile terminal device used by a user. Here, for convenience of explanation, a case where there is one portable terminal device 3 is shown as an example, but a plurality of portable terminal devices 3 may be provided. The mobile terminal device 3 is, for example, a mobile phone, a multi-function mobile phone called a so-called smart phone, a mobile information terminal, a portable music player capable of wireless communication, a biological management device capable of wireless communication, a tablet terminal, a so-called wristwatch type It is a wearable terminal such as a terminal. However, other mobile terminal devices may be used. The mobile terminal device 3 has a function for communicating with the floor sheet 2 by wireless communication, for example. The wireless communication used by the mobile terminal device 3 is, for example, wireless LAN, short-range wireless communication such as Bluetooth (registered trademark), infrared communication, or the like. However, wireless communication other than these may be used. In addition, when the reception part 201 of the floor sheet 2 mentioned later receives the input of the signal which shows the physical quantity added to the floor sheet 2 from a user, the portable terminal device 3 is omissible.

  The receiving unit 201 receives input of signals from one or more users located on the floor sheet 2. The signal received by the receiving unit 201 is, for example, a signal indicating a physical quantity such as pressure, vibration, or temperature on the floor sheet 2, specifically a signal indicating a physical quantity value. For example, the reception unit 201 receives an input of a signal indicating the magnitude of the force with which the user presses the upper surface of the floor sheet 2. For example, the receiving unit 201 receives input of signals output by one or more sensors (not shown) according to physical quantities received from one or more users. The sensor is, for example, a pressure sensor, a vibration sensor, a temperature sensor, a proximity sensor, or the like. The signal output by each sensor may be an unprocessed signal output by the sensor, and may be a physical quantity value detected by each sensor acquired using this signal, such as a pressure value or a temperature value signal. There may be. For example, the reception unit 201 responds to a force that one or more pressure sensors arranged in the floor sheet 2 or on the upper surface or the lower surface of the floor sheet 2 press the upper surface of the floor sheet 2 received from the user. An input of a signal indicating the pressure output is received. For example, only the pressure sensor that receives the pressure may output a signal corresponding to the received pressure, and the other pressure sensors may output a signal that does not accept the pressure, and do not output the signal. It may be. Further, for example, each vibration sensor that has received a vibration from the user may receive an input of a signal indicating the output vibration. Each sensor is, for example, arranged in the floor sheet 2 or on the floor sheet 2 and is located on the floor sheet 2 (for example, a user on the floor sheet 2 or the floor sheet 2). A physical quantity such as pressure, vibration, temperature, etc. is received from a moving user, etc., and a signal corresponding to the received physical quantity is output. For example, the sensors are arranged in a matrix or the like in the floor sheet 2 or on the floor sheet 2. Each sensor is arrange | positioned in the sheet | seat 2 for floors or on the sheet | seat 2 for floors like the pressure sensor which comprises a touch panel, for example. Each sensor may be considered as a part of the floor sheet 2, for example. Each sensor may be a part of the reception unit 201.

  In addition, the reception unit 201 may receive a signal that further includes an identifier of the sensor that has output the signal and position information on the floor sheet 2 of the sensor. When the sensor identifier is associated with the sensor position information, the position information of the sensor that outputs a signal can be acquired from the received sensor position identifier. The position information of the sensor is usually position information relative to the floor sheet 2 (for example, coordinates). However, it may be absolute position information such as coordinates represented by latitude and longitude.

  Note that the signal that the receiving unit 201 receives input may be position information of one or more sensors that detect a physical quantity (or detect a physical quantity that is equal to or greater than a threshold). The sensor position information may be considered as user position information, for example. This position information is the same as the position information described above.

  For example, the reception unit 201 may receive an input of a signal transmitted by wireless communication from the mobile terminal device 3 used by one or more users located on the floor sheet. Specifically, a signal transmitted from the mobile terminal device 3 through wireless communication or a communication line is received.

  In addition, the reception unit 201 may receive a signal that further includes position information of the mobile terminal device 3 that transmitted the signal from the mobile terminal device 3. The position information here is the same as the position information described above. The reception unit 201 receives signals output from the mobile terminal device 3 at a plurality of points, preferably at 3 or more points, and acquires position information of the mobile terminal device 3 that transmitted the signal from the reception intensity. Also good. The position information of the mobile terminal device 3 may be considered as, for example, the position information of the user who is the signal output source.

  In addition, the reception unit 201 may receive a signal further having a user identifier that is an identifier of the user who transmitted the signal from the user's portable terminal device 3. The user identifier may be the device identifier of the user's mobile terminal device 3. These are a user identifier, a user name, a user account, a user mail address, a user telephone number, a MAC address of the user portable terminal device 3, a serial number, and the like.

  The signal output (for example, transmitted) by the mobile terminal device 3 used by the user to the reception unit 201 may be any signal. For example, the mobile terminal device 3 used by the user may be a mobile phone, Alternatively, in the case of a device that can perform a voice call, the signal output to the reception unit 201 may be voice data of a voice for a call that is transmitted and received by the mobile terminal device 3.

  Moreover, the signal which the portable terminal device 3 outputs with respect to the reception part 201 may be the data transmitted / received by the portable terminal device 3 which a user utilizes, for example. For example, text data or image data transmitted / received by a mobile terminal device 3 via e-mail, SNS (social network service), short messaging service, miniblog called so-called twitter (registered trademark), etc. Also good.

  Information output from the portable terminal device 3 used by the user to the receiving unit 201 is, for example, biological information from the portable terminal device 3 that is a biological management device capable of wireless communication or a biological management device (not shown). The user's biometric information transmitted by the mobile terminal device 3 or the like that collects the information may be used. The biological information is information indicating, for example, the user's pulse rate, heart rate, respiratory rate, brain wave, body temperature, and the like. Information such as the user's walking speed and walking rhythm may also be considered biological information. The biological management apparatus is an apparatus that acquires these biological information. The biological management apparatus acquires such biological information for the purpose of managing the health of the biological body, for example. The biological management apparatus may include a sensor (not shown) for measuring these pieces of information. The walking speed, walking rhythm, and the like can be acquired by the same technique as that of a pedometer or the like, for example. The biological management apparatus may be a multifunctional mobile phone such as a smartphone that can execute application software for measuring or managing biological information, a wearable terminal, or the like.

  Moreover, the information which the portable terminal device 3 which a user uses outputs with respect to the reception part 201 may be the information regarding the music and image | video which the user is viewing, for example. For example, the information related to music and video may be, for example, information such as music and video titles, genres, and artist names associated with music and video, such as music data itself or video data itself. Also good. Further, it may be information indicating the rhythm or tempo or tone of music or video obtained by analyzing music data or video data. Since the process of acquiring information indicating the tempo and tone of music and video from music data and video data is a known technique, detailed description thereof is omitted here.

  Note that the signal that the receiving unit 201 receives an input from one mobile terminal device 3 may be position information of the one mobile terminal device 3. The position information of the mobile terminal device 3 may be considered as user position information, for example. This position information is the same as the position information described above.

  When the signal received by the receiving unit 201 is a signal transmitted from the user's mobile terminal device 3, the timing for receiving the signal does not matter. For example, when the user is making a voice call, for example, a signal may be received at regular intervals or at irregular intervals. In addition, every time text data or the like is transmitted / received from the mobile terminal device 3, the receiving unit 201 may receive a signal including the transmitted / received data.

  The storage unit 202 stores history information related to the history of signals received by the receiving unit 201. The history information is, for example, information in which at least a part of the signal received by the receiving unit 201 is associated with the received order, date and time. Stored in association with the received order may be stored in the order of reception, or may be stored in association with information indicating the order of reception. The history information is, for example, a set of information indicating physical quantities such as pressure and vibration received from a user associated with a time series, position information, biological information, and the like. The history information may further include a user identifier or the like.

  The storage unit 202 is preferably a non-volatile recording medium, but can also be realized by a volatile recording medium. The same applies to the following.

  The storage unit 203 stores the history information of the signals received by the reception unit 201 in the storage unit 202. For example, the storage unit 203 associates the signals received by the reception unit 201 with the order of reception, the date and time of reception, and the like. The associated information is accumulated in the storage unit 202 as history information. The date and time information can be acquired from, for example, a clock (not shown), NTP (Network Time Protocol), or the like. The same applies to the following.

  The recognition unit 204 recognizes the signal received by the reception unit 201. For example, the recognition unit 204 performs voice recognition on the voice data received by the receiving unit 201. The voice data here is, for example, voice data for a call. For example, the recognizing unit 204 obtains text data included in the voice data from voice data transmitted and received by the user for a call by voice recognition. May be acquired as a recognition result. Since a technique for acquiring information indicating emotion and information indicating a topic from text data is a known technique, detailed description thereof is omitted here. Further, a feature amount of speech may be acquired from speech data, and information obtained by estimating a user's emotion may be acquired as a recognition result using a machine learning result of the feature amount. Since the technique for estimating emotions from audio data is a known technique, a detailed description thereof is omitted here. For example, refer to the following URL: “URL: http://www.fujita.soft.iwait-pu.ac.jp/theses_f/Bachelor/2013b.pdf”.

  In addition, the recognizing unit 204 acquires the information indicating the user's emotion and the information indicating the topic from the text data transmitted and received by the mobile terminal device 3 used by the user received by the receiving unit 201 in the same manner as described above. Anyway. The topic acquired by the recognizing unit 204 may be the name of a song or the name of an artist who plays and provides a song. For example, a song title, artist name, or the like may be acquired from text data by using a clue phrase, a song name / artist name database (not shown), or the like.

  The recognizing unit 204 may recognize the current state of the user from the biological information received by the receiving unit 201. For example, even if it is determined whether the user is exercising or active, whether the user is relaxed, or the like, from the information on the pulse rate or respiratory rate received by the reception unit 201 Good. For example, if the pulse rate per unit time is higher than a threshold value, it may be determined that the user is exercising. Further, if the respiration rate per unit time is lower than the threshold value, it may be determined that the user is relaxed. Further, it may be recognized whether or not the user's body temperature is equal to or lower than a threshold value. If the user's body temperature is equal to or lower than the threshold value, it may be determined that the user is in a healthy state. If the user's walking rhythm is slower than a predesignated tempo, it is determined that the user is in a relaxed state if it is slow. May be determined to be in a hurry.

  The recognizing unit 204 performs voice recognition processing or the like on the music data received by the user received by the receiving unit 201, and obtains information such as the music title, artist name, music genre, and music rhythm. You may get it. In addition, the voice recognition processing may be performed to acquire information on the tune such as a gorgeous tune, a dark tune, and a relaxed tune.

  Note that the recognition unit 204 may be omitted when the signal received by the reception unit 201 is a signal that does not require recognition processing as described above, such as a signal indicating the force pressing the floor sheet 2.

  The recognition unit 204 can usually be realized by an MPU, a memory, or the like. The processing procedure of the recognition unit 204 is usually realized by software, and the software is recorded on a recording medium such as a ROM. However, it may be realized by hardware (dedicated circuit).

  The determination unit 205 determines color generation by the color generation layer 207 described later. For example, the determination unit 205 determines color development according to the signal received by the reception unit 201. For example, the determination unit 205 determines the color development by the color development layer 207 so that the color generation is at least different in accordance with the signal received by the reception unit 201. For example, the determination unit 205 determines a hue to be colored according to the value of the signal received by the reception unit 201. For example, the determination unit 205 stores information having a range of signal values received by the reception unit 201 in association with a hue range determined by the determination unit 205 in a storage unit (not shown). May acquire a hue value corresponding to the value of the signal received by the receiving unit 201 from the associated information. In addition, a calculation formula for calculating a hue value to be colored is prepared in advance using the value of the signal received by the reception unit 201 as an argument, and the value of the signal received by the reception unit 201 is included in this calculation formula. It may be substituted to calculate the hue value to be developed. For example, the determination unit 205 acquires the value of the hue to be colored by substituting the magnitude of the pressing force received by the reception unit 201 into the above calculation formula. That is, the hue to be colored is determined. Needless to say, the determination unit 205 may also determine color elements such as brightness and saturation other than the hue. The brightness and saturation may or may not differ depending on the signal received by the receiving unit 201.

  Further, the determination unit 205 further determines the color development mode, for example, the shape and size of the color development area, the position, the color development pattern, the change in color development over time, the intensity of the color development light, etc. according to the received signal. May be.

  For example, the determination unit 205 may determine a position where color development is performed according to a signal received by the reception unit 201. For example, the position of the floor sheet 2 indicated by the position information included in the received signal may be used as a center, for example, and the periphery of the position indicated by the position information may be colored according to the received signal. Alternatively, the floor sheet 2 may be divided into a plurality of areas, and coloring may be performed in the area including the position indicated by the position information included in the received signal.

  Further, for example, a coloring pattern or the like may be determined according to the received signal (for example, according to the magnitude of the signal). The color development pattern is, for example, a pattern shown by color development or blinking by repeatedly turning on and off the color development. For example, the determination unit 205 may determine the color development pattern based on whether or not the magnitude of the signal value exceeds a threshold value.

  The change with time of color development determined by the determination unit 205 is, for example, a change with time such as a color development position or a color to be developed, and may be an animation or the like due to color development. For example, the determination unit 205 prepares in advance an arithmetic expression for calculating the size of a light emitting area, for example, a radius, using the magnitude of the signal received by the reception unit 201 as an argument. By substituting the size, a color generation color, for example, a radius may be determined. Also, for example, the value of the signal received by the receiving unit 201 is set as a parameter of this information so that information for displaying an animation showing a coloring pattern whose parameters can be changed in advance is prepared. Thus, the animation to be displayed may be determined by coloring. For example, the determination unit 205 acquires a hue value corresponding to the pressing force using a signal indicating the magnitude of the pressing force on the floor sheet 2 received by the receiving unit 201, and the receiving unit 201 With respect to the magnitude of the force pressing on the floor sheet 2 indicated by the received signal, a value of a radius that increases continuously or stepwise as the magnitude of the force increases is acquired, and the acquired radius is maximum. It may be determined to output an animation of a ripple having a color having the hue acquired as described above so as to have a radius of.

  For example, the determination unit 205 determines color development using history information stored in the storage unit 202. For example, using the history information, the determination unit 205 acquires the sum of the magnitudes of the forces that press the upper surface of the floor sheet 2 applied to the floor sheet 2 within a predetermined period. The hue corresponding to the value is determined as the hue that the floor sheet 2 develops. For example, the range of hue values that can be developed by the coloring layer 207 is assigned to the range of values that can be taken by the sum of the magnitudes of pressing the upper surface of the floor sheet 2 of the history information. The unit 205 obtains the hue value corresponding to the sum of the values indicated by the history information from the information in which the range of the hue value and the total range of the magnitude of the force are associated with each other. Further, in this case, the determination unit 205 determines the position or region of the floor sheet 2 indicated by the position information included in each signal received by the reception unit 201 included in the history information as the color generation position, as the color generation position. Alternatively, a predesignated area of the floor sheet 2 may be determined as a color development area.

  Further, for example, one or more signals associated with each user identifier are acquired from the history information for each user identifier, and the stay on the floor sheet 2 of each user indicated by the acquired one or more signals Depending on the length of time, the hue to be colored for each user may be determined, and the position indicated by the position information of each user indicated by the history information may be colored with the determined hue. The length of stay time is, for example, the difference between the latest time and the earliest time indicated by two or more signals of each user included in the history information.

  In addition, the history information acquired within a predesignated time includes a signal associated with one user and having a specific signal equal to or greater than a predesignated threshold. In this case, the position indicated by the history information associated with the one user is colored with the color of the hue specified in advance, and the position indicated by the history information associated with the user not included in the predetermined number or more May be developed with colors of different hues.

  Further, for example, from the history information, a user identifier that has spent the longest time on the floor sheet 2 within a predetermined time period is detected, and one or more of the signals associated with the user identifier have It may be determined that the position indicated by the position information is colored with a hue corresponding to the magnitude of the force indicated by each signal.

  Further, the determination unit 205 may determine the color development according to the recognition result of the recognition unit 204. For example, the determination unit 205 may determine the hue to be colored according to the recognition result of the recognition unit 204.

  For example, the determination unit 205 may determine the hue to be colored according to the result of the voice call transmitted / received from the user's mobile terminal device 3, the voice recognition performed on the text data, or the recognition on the text data. . For example, the determination unit 205 determines the hue to be colored according to the voice recognition, the user's emotion (for example, mood) recognized from the text data, the topic, the user's situation, and the like. For example, when the recognition unit 204 determines that the user feels sad as a result of recognition performed on a voice call or text data transmitted / received from / to the mobile terminal device 3, a hue suitable for sadness, for example, When a cold hue such as blue is determined and it is determined that the user feels happy, a hue suitable for happiness, for example, a warm hue such as red may be determined. It is preferable to appropriately set the hue to be developed in what emotion, for example, depending on the place where the floor sheet 2 is disposed. The same applies to the sound described later.

  Further, the determination unit 205 may determine the hue to be colored according to the recognition result of the biological information, for example, the user's situation as the recognition result. For example, when the recognizing unit 204 determines that the user is in an exercise state according to the biological information, it determines a vibrant hue, for example, an orange hue, and the user is nervous. If it is determined, a hue that gives comfort, for example, a green hue, may be determined. It is preferable to appropriately set, for example, in what state and in what hue the color is developed depending on the place where the floor sheet 2 is disposed. The same applies to the sound described later. Similarly, different hue colors may be determined according to whether the user is in a healthy state, relaxed, whether the user is in an active state, or the like.

  Further, for example, the recognizing unit 204 may determine the hue to be colored according to the recognition result performed on the music data that the user is listening to. For example, if it is determined that the user is listening to slow-tempo music as a result of the recognition performed on the music data, a cool hue such as blue is determined, and the user listens to up-tempo music. If it is determined that the color is warm, a hue of a warm color such as orange or red may be determined.

  For example, it is possible to determine the hue according to the recognition result for the user as described above by preparing information in which the recognition unit 204 associates information that can be acquired as a recognition result with a hue. it can.

  The color development here may be considered as color development other than the color development in the initial state specified in advance. For example, when the floor sheet 2, specifically, a color developing layer 207 described later is colored in white as an initial state, the color determined by the determining unit 205 is considered to be a color other than white. Also good. The color development in the initial state may be considered as color development by the background color, for example. Further, the color development here may be considered to include light emission. Further, the color development in the initial state may be a state where the floor sheet 2 is not colored, a state where light is not emitted, or the like.

  Further, the determination unit 205 may determine to perform color development in the initial state when a predetermined condition is satisfied. For example, in a state where the color development in the initial state has been performed, when the condition that a predesignated time has elapsed from the time when the color development other than the color development in the initial initial state has been satisfied, the determination unit 205 It may be decided to perform color development in the initial state. Alternatively, when the condition that a predetermined time has passed since the reception unit 201 last received a signal is satisfied, it may be determined to perform color development in the initial state. In addition, in the case where coloring is performed in response to a signal having one user identifier received by the receiving unit 201, when the condition that a signal having another user identifier is received is satisfied, the previous one user It is also possible to return the colored portion corresponding to the signal having the identifier to the initial colored state. Further, when the condition that the date has changed since the start of color development is satisfied, the determination unit 205 may perform color development in the initial state.

  Further, the determination unit 205 determines the sound output from the sound output layer 208 described later. The sound determined by the sound output may be, for example, music, or a chime, buzzer sound, noise, environmental sound, or the like. Further, determining the sound may be determining the volume of the sound or determining the position where the sound is output. For example, the determination unit 205 determines a sound according to the signal received by the reception unit 201. For example, the sound corresponding to the magnitude of the signal received by the receiving unit 201 is determined. For example, information that associates the range of the signal magnitude with the output sound is prepared in advance in a storage unit (not shown), and the determination unit 205 corresponds to the range that includes the received signal magnitude. The sound is determined to be output. Further, the loudness of the sound to be output may be determined according to the magnitude of the received signal. Further, for example, the sound is determined according to the position information included in the signal received by the receiving unit 201. For example, information that associates the area on the floor sheet 2 with the output sound is prepared in advance in a storage unit (not shown), and the determination unit 205 includes the position indicated by the position information of the received signal. The sound corresponding to the region is determined to be output. Further, the position indicated by the position information included in the received signal may be determined as a position for outputting sound.

  For example, the determination unit 205 may determine a sound to be output using history information stored in the storage unit 202. For example, using the history information, the determination unit 205 acquires the sum of the magnitudes of the forces that press the upper surface of the floor sheet 2 applied to the floor sheet 2 within a predetermined period. You may determine as a sound which outputs the sound according to a value. For example, the sound may be determined as a sound that outputs a sound that increases continuously or in steps as the sum of the magnitudes of the forces increases.

  Further, the determination unit 205 may determine the sound to be output according to the recognition result of the recognition unit 204. For example, the determination unit 205 may determine the sound to be output according to the result of the voice call transmitted / received from the user's mobile terminal device 3, the speech recognition performed on the text data, or the recognition on the text data. . For example, if the topic acquired by the recognition unit 204 from the text data includes a song name or an artist name, the determination unit 205 indicates the music indicated by the recognized song name or the recognized artist name. The artist's music may be determined as the sound to be output. Moreover, the determination part 205 may determine the sound output according to a user's emotion acquired as a recognition result, or a condition. For example, when the recognition unit 204 recognizes that the user has a happy emotion, the sound may be determined to output a sound suitable for the happy emotion. In addition, since the technique which determines the sound and music output according to an emotion is a well-known technique in a music delivery technique etc., detailed description is abbreviate | omitted here.

  The determination unit 205 may determine the sound to be output according to the recognition result of the biological information by the recognition unit 204, for example, the user's situation as the recognition result. For example, when the recognition unit 204 recognizes that the user is exercising using biometric information, it is determined as a sound that outputs uptempo music suitable for the exercising situation, for example. Also good.

  The determination unit 205 may determine the sound to be output according to the recognition result by the recognition unit 204 for the music data that the user is listening to. For example, when the recognition unit 204 recognizes the name of an artist who plays a song of music data that the user is listening to, the sound may be determined to be output by the artist's music.

  The determination unit 205 can usually be realized by an MPU, a memory, or the like. The processing procedure of the determination unit 205 is usually realized by software, and the software is recorded on a recording medium such as a ROM. However, it may be realized by hardware (dedicated circuit).

  The output unit 206 performs color development with the hue determined by the determination unit 205. For example, the output unit 206 causes the coloring layer 207 to develop a color with the hue determined by the determination unit 205. Further, the output unit 206 may perform color development in the manner determined by the determination unit 205. Specifically, the output unit 206 outputs a signal for causing the coloring layer 207 to develop a color with the hue determined by the determining unit 205 to cause the coloring layer 207 to develop a color. Further, the output unit 206 outputs a signal for causing the color forming layer 207 to color in the manner determined by the determining unit 205 to the color developing layer 207. The signal that the output unit 206 outputs to the coloring layer 207 in order to perform coloring may be, for example, a signal for displaying a still image or a signal for displaying a moving image.

  The output unit 206 outputs the sound determined by the determination unit 205. For example, the output unit 206 outputs a signal for causing the sound determined by the determination unit 205 to be output to the sound output layer 208 to cause color development.

  The output unit 206 may be realized by output device driver software, or output device driver software and an output device.

  The sheet-like portion 20 is a sheet-like member having a structure in which a coloring layer 207, a sound output layer 208, and a protective layer 209 are laminated. Here, as an example, the protective layer 209 is composed of a first protective layer 2091 and a second protective layer 2092, and the sheet-like portion 20 is composed of the second protective layer 2092 and the color developing layer sequentially from the bottom. A case where a layer 207, a sound output layer 208, and a protective layer 209 are laminated is shown. The width, length, etc. of the sheet-like part 20 are not ask | required.

  The color development layer 207 performs color development of different hues according to the input received by the reception unit 201. In this embodiment, in particular, a case will be described in which the coloring layer 207 performs color development of different hues in response to the input of a signal received by the receiving unit 201. It may be considered that the development of a different hue according to the input of the signal received by the reception unit 201 is the execution of the development of a different hue according to the signal received by the reception unit 201. The color development with different hues is, for example, color development with at least different hues. Further, the coloring performed by the coloring layer 207 in response to the input received by the receiving unit 201 may be a coloring with a different coloring mode.

That the coloring layer 207 performs color development of a different hue according to the input received by the receiving unit 201 means that, for example, the coloring layer 207 generates a signal output from the output unit 206 according to the input received by the receiving unit 201. To perform color development, for example, in order to perform color development determined by the determination unit 205 according to the input received by the reception unit 201, the color generation layer 207 performs color generation according to a signal output from the output unit 206. It may be.

  In this embodiment, the development of a different hue according to the received input means that the development of a different hue is performed on at least two different inputs. It does not necessarily mean that different colors are developed for all different inputs. Depending on the accepted input, the color of the different hues is generated. According to the accepted input, the color of the two or more different hues is generated or any one of the two or more hues is generated. It may be considered to perform color development in hue.

  The coloring layer 207 performs color development with different hues according to the magnitude of the force indicated by the signal received by the receiving unit 201. Specifically, the coloring layer 207 performs the coloring determined by the determining unit 205 according to the magnitude of the force indicated by the signal received by the receiving unit 201 according to the signal output by the output unit 206. For example, the coloring layer 207 performs color development with the pattern determined by the determining unit 205 at the position determined by the determining unit 205 according to the hue determined by the determining unit 205.

  The coloring layer 207 may perform coloring with different hues according to the recognition result of the recognition unit 204. Specifically, the coloring layer 207 performs the coloring determined by the determining unit 205 according to the recognition result recognized by the recognition unit 204 for the signal received by the receiving unit 201 according to the signal output by the output unit 206.

  The coloring layer 207 is composed of, for example, one or more planar liquid crystal displays, organic EL displays, and plasma displays. The coloring layer 207 may be composed of a film-like display such as one or more organic EL film displays. Note that the color development in this embodiment may or may not involve light emission. The coloring by the coloring layer 207 may be considered as a display by the coloring layer 207.

  The sound output layer 208 outputs sound according to the input of the signal received by the receiving unit 201. The sound output layer 208 performing sound output in response to the input of the signal received by the reception unit 201 means that, for example, the sound output layer 208 is output by the signal output from the output unit 206 in response to the input received by the reception unit 201. When 208 outputs sound, to give a specific example, in order to output the sound determined by the determination unit 205 according to the input received by the reception unit 201, the sound output layer according to the signal output by the output unit 206 208 may output sound.

  The sound output layer 208 is disposed on or below the coloring layer 207. In FIG. 3, a case where the sound output layer 208 is disposed on the coloring layer 207 will be described as an example. The sound output layer 208 is, for example, one or more film-like speakers. A film-like speaker is a speaker comprised with the film of piezoelectric elements, such as a piezo film, for example. For example, the sound output layer 208 is composed of a plurality of film-like speakers arranged on the coloring layer 207, for example, in a matrix. Each film speaker is managed in association with a position on the floor sheet 2 where each film speaker is disposed, for example, a coordinate. Note that a film-like speaker or the like that can be controlled by designating the sound generation position by coordinates or the like may be used. The sound output layer 208 may be a layer composed of one or more flat speakers. In the case where the sound output layer 208 is disposed on the coloring layer 207, the sound output layer 208 is preferably a transparent layer, such as a transparent layer or a transparent milky white layer.

  The protective layer 209 is disposed on at least one of the upper surface side and the lower surface side of the coloring layer 207. The protective layer 209 is a layer for protecting the coloring layer 207 and the sound output layer 208. Here, the protective layer 209 includes a first protective layer 2091 disposed on the upper surface of the sound output layer disposed on the upper surface side of the coloring layer 207, and a second protective layer 2092 disposed on the lower surface side of the coloring layer 207. Will be described. As the first protective layer 2091, for example, a layer having the same structure as the first protective layer 1021 can be used. Further, as the second protective layer 2092, for example, a layer similar to the second protective layer 1022 can be used. However, the first protective layer 2091 and the second protective layer 2092 do not have to have a layer corresponding to the first cushion layer 1021a or the second cushion layer 1022a.

  In addition, on the floor sheet 2 in the present embodiment, specifically, it may be considered on the sheet-like portion 20, on the coloring layer 207, or on the protective layer 209.

  Next, an example of the operation of the floor sheet 2 will be described with reference to the flowchart of FIG.

  (Step S100) The output unit 206 performs color development in the initial state. Specifically, a signal for performing color development in the initial state is transmitted to the color development layer 207 to cause the color development layer 207 to perform color development in the initial state.

  (Step S101) The receiving unit 201 determines whether or not a signal input has been received. If accepted, the process proceeds to step S102. If not accepted, the process proceeds to step S206.

  (Step S102) The storage unit 203 stores the signal received in step S101 in the storage unit 202 in association with information such as date and time.

  (Step S103) The recognition unit 204 recognizes the signal received in step S101. If the signal received in step S101 is a signal that is not subject to recognition processing, this processing may be omitted.

  (Step S104) The determination unit 205 determines the color and sound to be output for the signal received in step S101. For example, when the recognition process is performed in step S103, the determination unit 205 determines the color and the sound according to the recognition result.

  (Step S105) The output unit 206 outputs the color and sound determined in step S104. Specifically, a signal for performing color development determined in step S104 is transmitted to the color development layer 207 to cause the color development layer 207 to perform color development. In addition, a signal for outputting the sound determined in step S <b> 104 is output to the sound output layer 208, and the sound is output to the sound output layer 208. Then, the process returns to step S101. When other sounds have already been output, a new sound may be output after both sounds have been output, or both sounds may be output. The same applies to color development.

  (Step S106) The determination unit 205 determines whether to perform output according to the history. For example, if the time specified in advance has elapsed since the time when the output corresponding to the history was performed immediately before, or if the output corresponding to the history was not performed immediately before, the time specified in advance has elapsed since the start of the operation. In such a case, it is determined that an output corresponding to the history is performed. If an output corresponding to the history is to be performed, the process proceeds to step S107. If not, the process proceeds to step S109.

  (Step S <b> 107) The determination unit 205 determines the color and sound to be output according to the history information stored in the storage unit 202. For example, the determination unit 205 outputs the history information associated with the date and time of the period from the time when the output according to the history is performed immediately before the time when the predesignated time has elapsed, or the output according to the history immediately before If not, the color and sound to be output are determined according to the history information associated with the date and time from the start of the operation until the point in time specified in advance.

  (Step S108) The output unit 206 outputs the color and sound determined in step S107, as in step S105. Then, the process returns to step S101.

  (Step S109) The output unit 206 determines whether or not a condition for performing color development in the initial state is satisfied. If satisfied, the process proceeds to step S110. If not satisfied, the process returns to step S101.

  In the flowchart of FIG. 4, the process ends when the power is turned off or the process ends.

  Hereinafter, a specific operation of the floor sheet 2 in the present embodiment will be described.

  FIG. 5 is a diagram illustrating a state in which the user A and the user B are on the sheet-like portion 20 of the floor sheet 2 arranged on the floor. Here, a case where the mobile terminal device 3 carried by the user A and the user B is a multi-function mobile phone such as a so-called smartphone will be described as an example. The mobile terminal device 3 of the user A is the mobile terminal device 3a, and the mobile terminal device 3 of the user B is the mobile terminal device 3b.

As shown in FIG. 5, the user A carrying the mobile terminal device 3 walks on the sheet-like portion 20 of the floor sheet 2 and makes a voice call from the mobile terminal device 3 a to another user by voice call. Suppose you send it. The mobile terminal device 3a has means for acquiring the coordinates of the current position such as GPS, acquires the coordinates of the current position, and together with the voice data of the voice transmitted above, the acquired coordinates of the current position, The mobile terminal device 3a transmits to the floor sheet 2 the device identifier of the device itself in a storage unit (not shown). It is assumed that the transmitted voice data is voice data “It was fun today”, the coordinates of the current position are (x ₁₀₀ , y ₁₀₀ ), and the device identifier is “abc @ def. Here, _the x _{100, y 100,} etc., and is an arbitrary value that indicates the coordinates. The same applies to the following.

  The reception unit 201 of the floor sheet 2 receives the voice data transmitted from the mobile terminal device 3a of the user A who is walking on the sheet-like part 20 of the floor sheet 2, the coordinates of the current position, and the device identifier. Receive. The reception of these pieces of information may be considered here as reception of signals by the reception unit 201. In addition, in order for the floor sheet 2 to accept input of signals only from the user on the sheet-like portion 20, the communicable range of the floor sheet 2 is limited to the area on the sheet-like portion 20. It is preferable to make it.

  The accumulating unit 203 accumulates, in the storage unit 202, information associated with the signal received by the accepting unit 201, that is, the received information, with the reception date and time acquired from a clock (not shown) or the like.

  FIG. 6 is a history information management table for managing history information stored in the storage unit 202. The history information management table has items of “voice”, “position”, “device ID”, and “date and time”. “Voice” is the file name of the voice data received by the receiving unit 201. “Position” is the coordinates of the current position of the mobile terminal device 3, “Device ID” is the device identifier, and “Date and time” is the date and time when the reception unit 201 receives the signal. Here, it is assumed that a plurality of history information has already been stored. In this specific example, since the audio data of history information is not used, the audio data may not be stored as history information.

  The recognizing unit 204 performs recognition processing on audio data in the signal received by the receiving unit 201 and acquires information indicating the emotion of the user who operates the mobile terminal device 3a. Here, a feature amount of speech is acquired from the speech data, and information that estimates a user's emotion is acquired using the feature amount and a machine learning result on the feature amount. For example, it is assumed that the recognition unit 204 acquires information “happiness” as a recognition result.

  FIG. 7 is a color management table that manages information indicating emotions acquired by the recognition unit 204 and colors to be associated with each other. The color management table is stored in advance in a storage unit (not shown), for example. The color management table has items of “emotion”, “hue”, “saturation”, and “lightness”. “Emotion” is text indicating the emotion acquired by the recognition unit 204. “Hue” is the value of the hue of the color to be developed, and here, the hue is represented by the value of the angle of the hue circle arranged in a ring. For example, 0 degrees is red, 120 degrees is green, and 240 degrees is blue. “Saturation” is the saturation of the color to be developed. Here, 0 is the lowest saturation and 100 (%) is the highest saturation. “Lightness” is the lightness of the color to be developed. Here, 0 is the lowest lightness, and 100 (%) is the highest lightness. Here, since the value of “hue” of each record (row) is different, it is determined that coloring of a different hue is performed when the value of “emotion” obtained from the text message is different.

  The determination unit 205 determines the color development from the color management table shown in FIG. 7 using information indicating the feeling of “happiness” acquired by the recognition unit 204. Here, the color development with the hue “0”, the saturation “30”, and the lightness “100” is determined.

Further, the determination unit 205 acquires coordinates (x ₁₀₀ , y ₁₀₀ ) indicated by the position information in the signal received by the reception unit 201, and determines these coordinates as the coordinates of the position where the coloring layer 207 is colored. . Here, the coordinate system of the coordinates indicating the position on the coloring layer 207 and the coordinate acquired by the mobile terminal device 3a are the same coordinate system (for example, a coordinate system represented by a combination of latitude and longitude). It is assumed that it is set.

  Here, it is assumed that the color development region is set in advance in a circular region having a radius specified in advance with the coordinates indicated by the position information as the center.

  Also, here, in a storage unit (not shown), the information indicating the emotion acquired by the recognition unit 204 and the sound to be output, here the sound file of the sound to be output, similar to the color management table shown in FIG. A sound storage table to be managed in association with each other is stored in advance, and the determination unit 205 stores, from this sound storage unit, an audio file “happiness.com” associated with information indicating the emotion “happiness” acquired by the recognition unit 204. It is assumed that “mp3” is determined as an audio file to be output.

Further, for example, in the sheet-like unit 20, when a plurality of sound output layers 208 are arranged in a matrix, the determining unit 205 has coordinates (position information indicated by position information in a signal received by the receiving unit 201 ( The sound output layer 208 arranged in the region including x ₁₀₀ , y ₁₀₀ ) is determined as the sound output layer 208 that generates a sound.

  Then, the output unit 206 causes the circular area 50 of the coloring layer 207 centered on the position determined by the determining unit 205 to be colored with the color of the color determined by the determining unit 205. For example, the color specified by the hue, saturation, and lightness is converted into an RGB color for color development.

  Further, the output unit 206 reproduces the audio file “happy.mp3” from the sound output layer 208 arranged in the area 51 determined by the determination unit 205.

  Further, as shown in FIG. 5, the user B walks on the sheet-like portion 20, and from the portable terminal device 3 b, a voice message “It can be laughed” is sent to another portable terminal device (not shown). Mobile terminal device 3b receives the voice data indicating this voice, the location information of mobile terminal device 3b used by user B, and the device identifier of mobile terminal device 3b used by user B. To the floor sheet 2.

  The reception unit 201 receives the transmitted signal in the same manner as the host. Then, the accumulation unit 203 accumulates history information about this signal in the storage unit 202 as in the upper level. Further, the recognition unit 204 performs voice recognition on the received voice data, recognizes information indicating the feeling of “laughter” and the like in the same manner as described above, and the determination unit 205 generates color and color according to the recognition result. The audio file to be output is determined, and the output unit 206 uses the color generation layer 207 and the sound output layer 208 to perform color generation and reproduction of the audio file.

  Here, as shown in FIG. 5, the circular area 60 of the coloring layer 207 has a color corresponding to the emotion of “laughter”, that is, the hue is “50”, the saturation is “90”, and the lightness is “100”. The sound file “color.mp3” corresponding to the emotion of “laughter” is reproduced from the sound output layer 208 that is colored in color and arranged in the region 61.

  In this way, when the emotions acquired from the voice data transmitted and received by each user for voice calls are different, the coloring layer 207 develops colors with different hues according to the received message.

  The above color development and sound output are terminated when, for example, a predesignated time has elapsed, and the initial color development, for example, no color development, or color development by a predesignated color is restored.

  Here, for example, it is assumed that it is time to perform color development using the history information accumulated in the storage unit 202. For example, it is assumed that a predetermined time, for example, “9:30”, “10:30”, or “11:30”, specifically “10:30” is reached. . Similar to the history management table shown in FIG. 6, the recognizing unit 204 sets the value of “time” from “9:31” to “10:30” on the same date in the latest history information management table. Records (rows) are detected, and in the detected records, records having the same “device ID” are detected, and the number of detected records is totaled for each “device ID”. Then, a value obtained by multiplying the total value by “10” is set as a hue, and a color with saturation and brightness set to “100” is determined as a color to be developed for each “device ID”. However, when the hue value calculated by multiplication exceeds “360”, the hue value is determined to be “360”. For example, if “5” records having “device ID” “pqrs @ dtuv...” Are detected, the hue is set to “50”. That is, the hue is dark yellow. Then, it is determined that the color determined for each “device ID” is developed in a shape designated in advance at the position indicated by the position information included in the record detected for each “device ID”. The shape designated in advance is assumed to be a circle, for example. For a portion where the colors to be developed overlap, it is determined that a color obtained by combining the overlapped colors in a pre-designated synthesis mode such as screen synthesis is developed. Then, in accordance with the determination by the determination unit 205, the output unit 206 causes the coloring layer 207 to color the position indicated by the position information included in the record detected for each “device ID” with the color determined for each “device ID”. Display color.

  FIG. 8 is a diagram illustrating a state in which the floor sheet 2 is colored according to the history information.

  As shown in FIG. 8, according to the number of pieces of history information corresponding to each user, the position indicated by the history information of each user is colored with different hues, thereby expressing the number of user histories with different hues. can do.

  It is assumed that the color development according to the history information is not returned to the initial color development over time unlike the above case. However, after this color development, when one user newly transmits a signal to the floor sheet 2 on the sheet-like portion 20, it is determined that the predesignated condition is satisfied, and the output unit 206 The color is restored to the initial state. Thereby, it is possible to prevent the history information display from disturbing the coloration by the newly received signal.

  As described above, according to the present embodiment, the floor can be dynamically decorated according to the input of the signal from the user by performing color development with different hues according to the signal received by the receiving unit 201 from the user. .

  In the above, voice data used for a voice call is received, and a hue or the like to be colored is determined according to information indicating user's emotion obtained by performing voice recognition on the received voice data. Although the case has been described, information on the pulse rate per unit time of the user may be received at each timing specified in advance instead of the voice data. For example, in this case, the user's state corresponding to the range including the received pulse rate is obtained from information having a pulse rate range stored in advance in a storage unit (not shown) and information indicating the user's state. Information (for example, text representing a state such as “normal state”, “excited state”, “relaxed state”) is acquired, and coloring according to the state of the user is the same as the coloring management table shown in FIG. Alternatively, it may be obtained from a management table having the user state and the color to be developed in association with each other. The same applies to the output sound. With such a configuration, it is possible to perform color development with an appropriate hue according to the state of the user. Moreover, you may make it acquire the information etc. which show a user's emotion by the combination of audio | voice data and biometric information, such as a user's pulse rate.

  In the above embodiment, each component may be configured by dedicated hardware, or a component that can be realized by software may be realized by executing a program. For example, each component can be realized by a program execution unit such as a CPU reading and executing a software program recorded on a recording medium such as a hard disk or a semiconductor memory. At the time of execution, the program execution unit may execute the program while accessing a storage unit (for example, a recording medium such as a hard disk or a memory).
