Summary of the Invention

Problems to be Solved by the Invention

[0004] Many modern people have various stresses, and the causes are also complex. Therefore, the relaxation effect may not be sufficiently obtained only by physical stimuli such as vibration. For this reason, a new type of relaxation device that does not rely solely on physical stimuli is required.

[0005]

Embodiments for Carrying Out the Invention

[0009] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In each drawing, unless otherwise specified, the same or corresponding components may be denoted by the same reference numerals and the description thereof may be omitted.

[0010] [Relaxation Device] Figures 1 and 2 respectively show photographs of the relaxation device 1 according to an embodiment from different angles. The relaxation device 1 is for use by being worn on a person's face and is a device that provides a relaxation effect to the wearer. In this specification, the "relaxation effect" refers to the effect of reducing negative psychological states such as anxiety (including state anxiety and trait anxiety), stress, fear, and depression. Due to the relaxation effect, the balance between the sympathetic nerve and the parasympathetic nerve can be adjusted, leading the mind and body to a relaxed state, and after using the device, a refreshed feeling for both the mind and body can be obtained, that is, a refresh effect can be obtained. According to the relaxation device of this embodiment, a relaxation effect can be obtained even with a short-term wearing, and a refreshed feeling can be obtained. The relaxation effect obtained by the relaxation device 1 according to the present disclosure will be described in more detail later.

[0011] As shown in FIGS. 1 and 2, the relaxation device 1 includes a plate-shaped main body 2 having transparency. Note that in this specification, "transparency" means that the transmittance of visible light is 20% or more. As long as the plate-shaped main body 2 has transparency, it may be colorless or colored. When it is colored, it is preferably colored in green, blue, or the like.

[0012] FIG. 3 shows an example of wearing the relaxation device 1 in the form shown in FIGS. 1 and 2. As shown in FIG. 3, the relaxation device 1 is worn such that the plate-shaped main body 2 covers both eyes. At this time, it is preferable that the distance between the eyes and the plate-shaped main body 2 is 10 mm or more and 25 mm or less. Also, the plate-shaped main body 2 extends from the forehead to the nose in the vertical direction of the face and extends to both sides of the face (across from the left side to the right side) in the horizontal direction of the face. However, the plate-shaped main body of the relaxation device according to the present disclosure only needs to have a shape and size that cover the wearer's eyes and does not necessarily have to extend to the side portions of the face.

[0013] In this specification, when the relaxation device 1 is worn, the directions corresponding to the vertical direction, horizontal direction, and front-rear direction of the wearer's face are respectively referred to as the vertical direction (z-direction), horizontal direction (x-direction), and front-rear direction (y-direction) of the relaxation device 1. When the plate-shaped main body 2 is not curved, the front-rear direction (y-direction) is the thickness direction of the plate-shaped main body 2 at any position. Also, the side located above the face during wearing is called the upper side, and the side located below the face is called the lower side. Furthermore, the side of the plate-shaped main body 2 facing the face is called the inner side (face side), and the opposite side is called the outer side (non-face side). The inner surface of the plate-shaped main body 2 is called the inner surface 2b, and the outer surface is called the outer surface 2a. When the plate-shaped main body 2 is curved in one direction, the direction of the curvature may be called the circumferential direction.

[0014] As shown in FIGS. 1 and 2, the relaxation device 1 may be provided with, as an arbitrary configuration, a pressing portion 3 corresponding to the side portion of the face, a hole 4 for accommodating the aromatic substance container 8, and a central protrusion 6. The pressing portion 3 is provided on the inner surface 2b of the plate-shaped main body 2 and is a convex portion that can press an appropriate position on the wearer's temple or its surroundings when the relaxation device 1 is worn. The aromatic substance container 8 is a container configured to accommodate an aromatic substance and gradually emit an aroma. The aromatic substance container 8 can be accommodated in the holes 4 respectively formed on both side portions of the plate-shaped main body 2. The central protrusion 6 is at least a pair, preferably two pairs of upper and lower protrusions with different sizes, protruding from the inner surface 2b at the center in the horizontal direction (x-direction) of the plate-shaped main body 2 and capable of abutting on both sides of the upper part of the wearer's nose. When worn, the relaxation device 1 is supported by the central protrusion 6 at the upper part of the wearer's nose.

[0015] FIG. 4 is a perspective view schematically depicting the relaxation device 1 in a state where the pressing portion 3 and the aromatic substance container 8 are not provided. FIG. 5 shows a cross-sectional view of the relaxation device 1 shown in FIG. 4 cut along a plane orthogonal to the vertical direction (z-direction) approximately at the center in the vertical direction (z-direction). FIG. 6 shows a cross-sectional view of the relaxation device 1 shown in FIG. 4 cut along a plane orthogonal to the horizontal direction (x-direction) at the center in the horizontal direction (x-direction).

[0016] As shown in FIGS. 4 to 6, the plate-shaped main body 2 according to the present embodiment is curved as a whole. More specifically, as shown in FIGS. 4 and 5, it is curved in the left-right direction (x direction) such that the center in the left-right direction is convex outward (non-face side), that is, the center of the radius of curvature is located on the face side. The radius of curvature of the curvature in the left-right direction may be 60 mm or more and 140 mm or less at the position in the center in the left-right direction. Further, as shown in FIGS. 4 and 6, it is curved in the up-down direction (z direction) such that the center in the up-down direction is convex inward (face side), that is, the center of the radius of curvature is located on the non-face side. The radius of curvature of the curvature in the up-down direction may be 60 mm or more and 120 mm or less at the position in the center in the up-down direction.

[0017] As shown in FIGS. 1 to 6, on the outer surface 2a of the plate-shaped main body 2, irregularities W of a predetermined shape are formed in at least a range that enters the wearer's field of view during wearing. The irregularities W are irregular wave-shaped irregularities. The irregular wave shape is, for example, a shape in which the size and / or pitch of the convex portions are not constant. Further, the irregularities W are of a size visible to the naked eye, and the diffuse reflection at the irregularities W can be confirmed visually. In the form shown in FIGS. 1 to 6, the irregularities W are formed on the outer surface 2a, but the irregularities W may be formed on at least one surface of the plate-shaped main body 2. That is, the irregularities W may be formed on the inner surface 2b, or may be formed on both the outer surface 2a and the inner surface 2b. In this specification, the "pitch" of the wave shape refers to the distance along the extending direction (plane direction) of the plane between adjacent maximum points.

[0018] [Uneven shape of plate-shaped main body] The irregularities W have a shape including at least a predetermined irregular first wave shape (small wave shape) with a relatively small pitch. More specifically, the irregularities W include a shape including a first wave shape (small wave shape) passing through points moved at random heights from a plurality of reference points in a lattice shape spaced apart at a predetermined interval projected onto at least one surface (the outer surface 2a in the form of FIGS. 1 to 6) of the plate-shaped main body 2.

[0019] Furthermore, since the unevenness W enables more complex irregular reflection and can improve the visual relaxation effect, it is preferable that the unevenness W has a shape formed by synthesizing the first wave shape (small wave shape) and a predetermined irregular second wave shape (large wave shape) with a relatively large pitch. Note that the size of the pitch of a predetermined wave shape pattern does not necessarily refer to a specific value or range, but rather refers to the relative size of the average pitch when comparing two different wave shape patterns.

[0020] When the relaxation device 1 according to the present disclosure is worn, the wearer's eyes are covered by the plate-shaped main body 2 (FIG. 3). As described above, since the plate-shaped main body 2 has transparency and has a predetermined irregular uneven shape on at least one surface, the light hitting the plate-shaped main body 2 is irregularly reflected by the unevenness, that is, irregularly reflected. Therefore, when the wearer looks at the other side (outside) of the plate-shaped main body 2 through the plate-shaped main body 2, a unique visual field is created by the irregular reflection of the light. For example, the wearer can see a scene as if looking up at the water surface from underwater. And the unique scenery obtained due to such irregular reflection of light can give a relaxation effect to the wearer. The relaxation effect obtained by seeing such a scenery is a relaxation effect based on visual information (visual relaxation effect), and is particularly effective in improving mental states such as reducing anxiety. Also, it can be used by users who want to avoid physical stimuli such as vibration due to injury or the like, or who do not prefer physical stimuli. Furthermore, some conventional relaxation devices generate sound due to physical stimuli, and there are users who feel uncomfortable with the sound, but the relaxation device of the present disclosure that can provide a visual relaxation effect has no such sound problem.

[0021] When the relaxation device 1 according to the present disclosure is worn, light can reach the wearer's eyes through the plate-shaped main body 2. Therefore, when the wearer looks through the plate-shaped main body 2 to the other side (outside), the wearer can recognize the light and dark state on the other side, and can at least vaguely recognize the scenery on the other side. For example, the movement of an object or the like on the other side of the plate-shaped main body 2 can also be recognized. Among conventional relaxation devices, there are some that block the wearer's field of vision so that light does not enter the wearer's eyes, or that allows as little light as possible to enter. However, the relaxation device 1 according to the present disclosure is completely different from such conventional devices. Visual information obtained by opening the eyes and looking at the scenery through the plate-shaped main body 2 can reduce anxiety, stress, etc. Therefore, it is possible to avoid accidentally falling asleep during wearing, etc., and it is suitable when you want to refresh yourself in a short time during breaks in work, etc.

[0022] Incidentally, the preferable wearing time of the relaxation device 1 according to the present disclosure may be 30 seconds or more and 300 seconds or less, although it depends on the specific configuration of the relaxation device.

[0023] Hereinafter, the shape of the unevenness W will be described in detail together with an example of its forming method. FIG. 7 shows a flowchart of a method for forming the shape of the unevenness W. As shown in FIG. 7, the method for forming the uneven shape may include a step of forming a second wave shape (large wave shape) (S10), a step of forming a first wave shape (small wave shape) (S20), and a synthesizing step of synthesizing the second wave shape (large wave shape) and the first wave shape (small wave shape) (S30). In the present specification, "forming a shape" refers to generating shape data, but may include actually shaping the surface of the plate-shaped main body 2.

[0024] The second wave shape (large wave shape) forming step (S10) includes, as shown in FIG. 8, providing a plurality of rows of second reference points spaced along a predetermined direction over a second reference plane, while separating them from each other (S11), moving each of the second reference points to a random height to obtain moved points (S12), and obtaining a second wave shape passing through the moved points (S13). Further, the first wave shape (small wave shape) forming step (S20) includes, as shown in FIG. 9, projecting a plurality of grid-like points spaced at a predetermined interval onto a first reference plane to obtain first reference points (S21), moving the first reference points to a random height to obtain moved points (S22), and obtaining a first wave shape passing through the moved points (S23). Note that the predetermined interval between the grid-like points before projection in the step of projecting the first reference points (S21) may be 1 mm or more and 10 mm or less.

[0025] The order of the second wave shape forming step (S10) and the first wave shape forming step (S20) is arbitrary, and either one may be performed first. Alternatively, after performing the second wave shape forming step (S10) and the first wave shape forming step (S20) simultaneously, the data obtained in each step may be combined.

[0026] Hereinafter, based on an example in which data of the shape of the unevenness W is acquired by performing the first wave shape forming step (S20) after performing the second wave shape forming step (S10) for the method of forming the shape of the unevenness according to the present disclosure, an explanation will be given.

[0027] <Formation of the Second Wave Shape (Large Wave Shape)> First, with reference to FIGS. 10 to 12, the second wave shape (large wave shape) forming step (S10) will be described. FIG. 10 shows a state in which the outer surface 2a is the second reference plane F before the formation of the second wave shape (large wave shape). 02 In this example, since the second wave shape (large wave shape) forming step (S10) is performed first, the second reference plane F 02 is a surface on which no unevenness is formed. However, when another wave shape step, for example, the first wave shape (small wave shape) forming step (S20), is performed first, unevenness may be formed on the second reference plane F 02 . The second reference plane F 02It has the same shape as the outer surface 2a of the finished plate-shaped body 2 except for having no irregularities. That is, as a whole, it is curved in the left-right direction (x direction) so that the center in the left-right direction (x direction) protrudes outward, and is curved in the up-down direction (z direction) so that the center in the up-down direction (z direction) protrudes inward.

[0028] For the formation of the second wave shape (large wave shape), first, a second reference plane F 02 is provided with a plurality of rows of points (second reference points) spaced apart along a predetermined direction at intervals (S11). For this purpose, for example, as shown in FIG. 10, on the second reference plane F 02 a plurality of reference lines C1 to C11 drawn from the upper side to the lower side while being spaced apart from each other are extracted. In the example shown in FIG. 10, since the reference lines C1 and C11 are drawn at both ends in the circumferential direction of the second reference plane F 02 (outer surface 2a), nine reference lines are extracted excluding both ends in the circumferential direction. Therefore, in this example, extracting the reference lines C1 to C11 means, in other words, dividing the second reference plane F 02 into 10 parts in its circumferential direction. The number of divisions by such reference lines is not limited to 10, and may be 5 or more and 20 or less depending on the size of the plate-shaped body 2. Also, in the example shown in FIG. 10, the spacing between the reference lines C1 to C11 is equal, but the spacing between the plurality of reference lines may be irregular. However, it is preferable that the plurality of reference lines are provided symmetrically. The circumferential spacing between the reference lines may be 15 mm or more and 60 mm or less from the viewpoint of generating appropriate diffuse reflection with the irregularities and improving the visual relaxation effect.

[0029] Then, on each of the above reference lines, a plurality of reference points (second reference points) are set as control points at intervals, and a plurality of columns of reference points along the vertical direction (y direction) are obtained. Fig. 11(a) shows a view of a reference line C6 drawn at the center in the left-right direction (x direction) among the above reference lines as an example, as viewed in the left-right direction (x direction). Fig. 11(b) shows the second reference points P, P,... set on the reference line C6. The interval between the second reference points on the reference line may be regular, but as shown in Fig. 11(b), it is preferably taken randomly. The second reference points on the reference line can also be provided at the upper and lower ends. The number of the second reference points P excluding the upper and lower ends on one reference line may be 3 or more and 10 or less depending on the size of the plate-shaped body 2, and is preferably 4 or more and 6 or less. From the viewpoint of generating appropriate diffuse reflection and improving the visual relaxation effect, the interval in the vertical direction (y direction) between the second reference points P, P,... may be 10 mm or more and 15 mm or less.

[0030] Subsequently, the set second reference points P, P,... are moved at random heights H to obtain the points P', P' after movement (S12). For example, as shown in Fig. 11(c), each of the second reference points P, P,... set on the reference line C6 is moved so as to be separated from the reference line C6 by a random distance, that is, from the second reference plane F 02 by a random distance. Here, the "height" for moving the reference point refers to the distance from the reference plane in the thickness direction of the plate-shaped body 2 to be obtained and away from the reference plane. As in this example, when there are no irregularities formed on the second reference plane F 02 , the above thickness direction is the normal direction of the second reference plane F 02 . Also, the "height" can be either a positive value or a negative value. That is, in this example, as shown in Fig. 11(c), when the second reference point P moves forward (+y direction), the height can be a positive value, and when it moves backward (-y direction), the height can be a negative value. In step S12, the maximum value of the absolute value of the height (the moving distance from the second reference plane F 02 ) H to be moved is preferably 6 mm or less, more preferably 4 mm or less, and even more preferably 2 mm or less.

[0031] In the direction of moving a plurality of second reference points P, P, ... on one reference line, with respect to the second reference plane F 02 both the plus direction and the minus direction are mixed, and for example, the plus direction and the minus direction may be repeated substantially alternately.

[0032] When the movement (S12) of the second reference points P, P, ... is completed, a second wave shape (large wave shape) passing through the obtained moved points P', P', ... is obtained (S13). That is, as shown in FIG. 11(d), the moved points P', P', ... are smoothly connected. The same operation is performed for all the reference lines, and as shown in FIG. 12, wavy lines C1' to C11' after the reference lines C1 to C11 are deformed are obtained. Further, by smoothly connecting the moved points P', P', ... in the circumferential direction as well, the unevenness W L of the second wave shape (large wave shape) can be formed to obtain a surface F2 (S13).

[0033] <Formation of the first wave shape (small wave shape)> Subsequently, with reference to FIGS. 13 to 15, the first wave shape (small wave shape) forming step (S20) will be described. FIGS. 13(a) to (e) show the overall flow of the first wave shape (small wave shape) forming step (S20). FIG. 13(a) shows the reference plane (first reference plane) F 01 of the plate-shaped body before the first wave shape (small wave shape) is formed. In this example, since the above-described second wave shape (large wave shape) step (S10) has been performed first, the first reference plane F 01 is the outer surface 2a in a state where the unevenness W L of the second wave shape (large wave shape) is formed. However, if there is no wave shape forming step before the first wave shape (small wave shape) forming step (S20), the first reference plane F 01 can be a surface without unevenness.

[0034] In the first wave shape (small wave shape) forming step (S20), first, a plurality of lattice-shaped points separated at a predetermined interval are projected onto the first reference plane F 01 to obtain first reference points p, p, .... More specifically, first, as shown in FIG. 13(b), the first reference plane F 01project a lattice (mesh-like) line across, that is, the first reference plane F 01 is meshed or mesh processing is performed on the first reference plane F 01 For example, attach a lattice formed by combining a plurality of equally spaced lines extending from the upper side to the lower side and a plurality of equally spaced lines extending in the circumferential direction. Fig. 14 shows an enlarged view of the first reference plane F 01 (outer surface 2a) of Fig. 13(b). Then, as shown in Fig. 13(c), extract the intersections of the lattice and use these point groups as the first reference points. Fig. 14 shows the first reference points p, p,....

[0035] As described above, the first reference points p, p,... are a plurality of lattice-like point groups, but the intervals between the first reference points p, p,... arranged in the vertical direction (z direction) and the intervals between the first reference points p, p,... arranged in the circumferential direction may be the same or different. That is, the compartments separated by the lattice-like lines formed on the plane before projection may be square or rectangular. In this example, the lattice-like lines are along the vertical direction and the circumferential direction, but lines may be provided along a direction deviating from the vertical direction and a direction orthogonal thereto.

[0036] The first reference plane F 01 The interval between adjacent points of the plurality of lattice-like points to be projected onto may be an interval of 1 mm or more and 10 mm or less, preferably 2 mm or more and 8 mm or less, and more preferably 3 mm or more and 6 mm or less. By setting the interval within the above range, appropriate diffuse reflection on the surface of the plate-like body 2 can be obtained, and the above-described effect that a scenery as if looking at the water surface from underwater can be seen and a visual relaxation can be obtained can be improved.

[0037] After a plurality of first reference points p, p,... are obtained, move the first reference points p, p,... to random heights (S22). Fig. 13(d) shows the group of moved points obtained after moving a plurality of first reference points. Also in the first wave shape (small wave shape) forming step (S20), the meaning of "height" is the same as that described in the second wave shape (large wave shape) forming step (S10) and may be the thickness direction of the plate-like body 2 to be obtained. Also, the first reference plane F01 When using a surface without unevenness, the direction of the height (the direction of point movement) can be the normal direction of the first reference plane F 01 . Also, similar to the case of the second wave shape (large wave shape) forming step (S10), the height for moving the first reference points p, p,... can also include positive and negative values.

[0038] To explain the step (S22) of moving the first reference points p, p,..., Fig. 15 schematically shows a cross-section taken along the line A-A of Fig. 14. The cross-section along the line A-A is a cross-sectional view obtained by cutting the first reference plane F 01 vertically along the center in the left-right direction (y direction). In Fig. 15(a), the first reference plane F 01 is shown by a dotted line. In this example, a plurality of first reference points p, p,... are provided at equal intervals in the vertical direction (z direction) along the first reference plane F 01 . Then, as shown in Fig. 15(b), each of the first reference points p, p,... is moved vertically (in the z direction) to a random height h to obtain a plurality of moved points p', p',... respectively.

[0039] The height h for moving the first reference point p, that is, the moving distance in the thickness direction, is preferably at most 9 mm. This height may more preferably be 1.5 mm or more and 7.5 mm or less, and still more preferably 3 mm or more and 6 mm or less. By setting the height (moving distance) as described above, appropriate diffuse reflection can be obtained, and the above-described effect that a scenery as if looking at the water surface from underwater can be seen and visual relaxation can be obtained can be further enhanced. Note that as the height h increases, the impression of the waves on the appearance of the plate-like main body 2, for example, the impression of the unevenness W waves when holding the relaxation device 1 in the hand, becomes stronger. However, just because the impression of the waves on the appearance becomes stronger, it does not mean that the impression of looking at the water surface from underwater felt by the wearer during wearing becomes stronger. If the height h is too large, the diffuse reflection of light perceived by the wearer decreases, and the feeling of looking at the water surface from underwater is impaired.

[0040] Further, as shown in Fig. 15(b), smoothly connect the points p' after movement. This operation is performed over the entire outer surface 2a to obtain a first wave shape (small wave shape) passing through the points p' after movement (S23). That is, a surface F1 with an uneven shape including the first wave shape (small wave shape) is obtained. In this example, the uneven shape obtained after the first wave shape (small wave shape) forming step is the same as the shape of the unevenness W formed on the plate-shaped main body 2 of the relaxation device 1 which is the finished product.

[0041] In this example, as the first reference surface F 01 in the first wave shape (small wave shape) forming step (S20), the surface F2 obtained in the second wave shape (large wave shape) forming step (S10), that is, the surface on which the unevenness W L has already been formed is used. Therefore, when performing the first wave shape (small wave shape) forming step (S20), a step (S30) of synthesizing the second wave shape (large wave shape) and the first wave shape (small wave shape) is also performed. However, the first reference surface F 01 in the first wave shape (small wave shape) forming step (S20) can be a reference surface without unevenness, the first wave shape (small wave shape) can be formed to obtain data, and the data can be synthesized with the data of the second wave shape (large wave shape) formed by the second wave shape (large wave shape) forming step (S10).

[0042] Note that the operations related to the formation of the second wave shape (large wave shape) (S10), the formation of the first wave shape (small wave shape) (S20), and the synthesis of the second wave shape (large wave shape) and the first wave shape (small wave shape) (S30) described above can be performed using a visual programming language such as Grasshopper (registered trademark).

[0043] Once the data of the obtained unevenness W is obtained, based on that data, the plate-shaped main body 2 can be shaped. As the material of the plate-shaped main body 2, in order to avoid the state of diffuse reflection changing due to deformation, it is preferable to use a material having a certain degree of rigidity or difficulty in deformation. The plate-shaped main body 2 can be shaped by 3D printing, casting, etc. of resin.

[0044] [Other configurations] <Pressing part> As described with reference to FIGS. 1 and 2, the relaxation device 1 according to the present disclosure is provided with pressing parts 3, 3. The pressing parts 3, 3 are a pair of members provided at positions on the inner surface 2b of the plate-shaped main body 2 corresponding to both sides of the wearer's face during wearing, and protrude from the inner surface 2b. FIG. 16(a) shows a perspective view of the pressing part 3, and FIG. 16(b) shows a cross-sectional view taken along line B-B of FIG. 16(a).

[0045] As shown in FIG. 3, when worn, the relaxation device 1 is worn such that the plate-shaped main body 2 sandwiches both sides of the face. That is, the plate-shaped main body 2 is worn so as to continuously extend from one side part of the wearer's face to the other side part and is supported on both sides of the face. At this time, specifically, the plate-shaped main body 2 is supported by the pressing parts 3 protruding from the inner surface 2b. Note that the plate-shaped main body 2 can also be supported by the central protrusion 6 at the center in the left-right direction (x direction), but by dispersing the support points between the central protrusion 6 and the pressing parts 3, 3, the burden on the face is reduced.

[0046] In addition to the above-described support function, the pressing part 3 may also have a pressing function of pressing and stimulating the wearer's temples or the periphery of the temples during wearing. Simply saying the temples or the periphery of the temples, the specific positions where it feels good to be pressed vary depending on the wearer. Therefore, when manufacturing the relaxation device 1, it is preferable to make the pressing part 3 a separate body from the plate-shaped main body 2 and customize the position of the pressing part 3 on the plate-shaped main body 2 for each wearer (described in detail later).

[0047] Since the pressing part 3 is a part that directly contacts the face and presses the face, it is preferably formed of a material having higher flexibility or elasticity than the plate-shaped main body 2. Specific materials for the pressing part 3 include resins, elastomers such as silicone elastomers, and rubbers such as NBR.

[0048] The pressing part 3 may be a substantially cylindrical member. The diameter d of the pressing part 3, or the equivalent diameter (the diameter of a circle with an area equal to the cross-sectional area of the non-circular pressing part) when the cross-section is a shape other than circular, may be 10 mm or more and 40 mm or less. Also, the height j of the pressing part 3 may be 6 mm or more and 18 mm or less.

[0049] <Aromatic substance container> Also, as shown in FIGS. 1 and 2, the relaxation device 1 according to the present disclosure is provided with an aromatic substance container 8. The aromatic substance container 8 can be housed in holes 4 formed in the vertical direction on both side portions (both circumferential ends) of the plate-shaped main body 2. An aromatic substance is housed inside the aromatic substance container 8. Thereby, when the relaxation device 1 is worn, the aroma from the housed aromatic substance is gradually released. Since the hole 4 communicates with a slit 4a (FIG. 4) that opens to the inner surface 2b of the plate-shaped main body 2, the aroma is mainly released from the slit 4a.

[0050] FIG. 17 shows a perspective view of the aromatic substance container 8. In one embodiment, the aromatic substance container 8 has a cylindrical container body 8a, and a plurality of small holes 8b may be formed in the container body 8a. Also, after housing the aromatic substance, a cap 8c can be attached to the container body 8a. As shown in FIG. 17, since the small holes 8b are arranged in a spiral shape with the vertical direction as the axis, the advantage is obtained that the strength of the aroma hardly changes no matter in which direction the aromatic substance container 8 is housed.

[0051] As the aromatic substance housed in the aromatic substance container 8, those known in the fields of relaxation, beauty, health, etc. can be used. Since the relaxation effect is high when used in combination with the relaxation device according to the present embodiment, as the aromatic substance, limonene, linalool, etc. are preferable. Also, the aromatic substance is preferably housed in a particulate, capsule-like, or other form.

[0052] [Method for manufacturing a relaxation device] Next, a manufacturing method for the entire relaxation device 1 as described above will be explained. Since the shape and size of the face vary among wearers, the relaxation device 1 of the present disclosure that is pressed against the face so as to sandwich the face from both sides is preferably customized for each wearer.

[0053] A manufacturing method for a relaxation device according to an embodiment includes a relaxation device main body that is worn so as to cover the wearer's eyes across one side portion of the wearer's face to the other side portion and sandwich the face from both side portions, and a convex portion protruding from the inner surface of the relaxation device main body. The manufacturing method of the relaxation device may include determining a pressed position on the wearer's face where the wearer feels comfortable when pressed, obtaining three-dimensional shape information of the wearer's face, and shaping the relaxation device based on the pressed position and the three-dimensional shape information of the face so that the convex portion can press the pressed position during wearing.

[0054] Here, FIG. 18 shows a specific example of the flow of the manufacturing method for the relaxation device according to the present embodiment. As shown in FIG. 18, the manufacturing method for the relaxation device may include an information acquisition step (S1) and a shaping step (S2).

[0055] <Information Acquisition Step (S1)> The information acquisition step (S1) includes the wearer determining a pressed position on the wearer's face where the wearer feels comfortable when pressed (S1a). More specifically, the pressed position is a pressed position pressed by the pressing portion 3 and is a position in the side region of the face, and is selected from the temples and the periphery of the temples. The determination of the pressed position (S1a) may be performed by the wearer himself / herself or with the help of an assistant through an interview or the like. When searching for the pressed position where the wearer feels comfortable when pressed, it is often the case that the side portion of the face is actually pressed with the pulp of the finger for consideration. Once the pressed position is found, it is preferable to record the center position of the pressed position on the wearer's face. The recording may be, for example, actually marking the side portion of the wearer's face and taking a photo of it.

[0056] The information acquisition step (S1) further includes acquiring three-dimensional shape information (3D shape information) of the wearer's face (S1b). The three-dimensional information of the wearer's face can be obtained by a device capable of 3D scanning and acquiring 3D shape information. For example, Shining 3D EinScan or the like can be used. After acquiring the 3D shape information (S1b), at least information on the width of the face (the distance between the cheeks) is extracted from the 3D shape information. Also, from the 3D shape information, the curvature of the face in the left-right direction, the length in the front-back direction between the root of the nose and the cheek position, etc. can also be extracted. In the 3D image of the face generated from the 3D shape information of the face, the pressed position that is felt to be comfortable when pressed may be marked. Note that in the information acquisition step (S1), the necessary dimensions may be manually measured without using a device.

[0057] <Modeling step (S2)> In the modeling step (S2), based on the pressed position on the wearer's face and the 3D shape information of the wearer's face acquired in the information acquisition step (S1), the relaxation device 1 is modeled (S2).

[0058] First, the plate-shaped main body 2 is modeled or selected (S2a). At this time, based on the width of the wearer's face (the distance between the cheeks) in particular, the distance between the inner surfaces 2b at the position where the inner surfaces 2b face each other at the rear in the plate-shaped main body 2 is larger than the width of the face, preferably 5 mm or more and 40 mm or less larger, and the plate-shaped main body 2 is modeled. Alternatively, an appropriate plate-shaped main body 2 is selected from a plurality of plate-shaped main bodies 2 having different sizes that have been modeled in advance. Note that regarding the formation of the uneven shape in the modeling of the plate-shaped main body 2, it is as described above.

[0059] Subsequently, one or more of the positions, sizes, and shapes of the pressing portions 3 formed on the inner surface 2b of the plate-shaped body 2 are determined. At this time, for example, the plate-shaped body 2 without the pressing portion 3 shaped or selected in the above step S2a is applied to the face, and the central protrusion 6 provided on the plate-shaped body 2 is made to face the vicinity of the nasal bone from between the eyebrows, so as to determine a comfortable relative position of the plate-shaped body 2 with respect to the face. In this state, the position of the pressing portion 3 is determined such that the desired pressed position on the wearer's face coincides with the center of the pressing portion 3 on the inner surface 2b of the plate-shaped body 2.

[0060] Also, for example, after determining a comfortable relative position of the plate-shaped body 2 with respect to the face as described above, in this state, the separation distance between the desired pressed position on the wearer's face and the inner surface 2b of the plate-shaped body 2 is measured, and the height (j in FIG. 16(b)) of the pressing portion 3 is set to be more than 0 mm and 5 mm or less than the separation distance.

[0061] Note that the shape of the pressing portion 3 includes the angle at which the pressing portion 3 protrudes from the inner surface 2b. The pressing portion 3 shown in FIG. 16 protrudes perpendicularly from the inner surface 2b, but it may have a shape that protrudes at an angle in a direction deviating from the perpendicular direction, for example, forward or backward from the perpendicular direction.

[0062] In the determination of the configuration of the pressing portion 3 (S2b), the positions, sizes, and shapes of the pressing portions 3 can be determined to be symmetric left and right. However, among wearers, there are those whose comfortable pressed positions are different between the left and right. In that case, it is preferable to determine the positions and the like of the left and right pressing portions 3 on the plate-shaped body 2 respectively.

[0063] After the configuration of the pressing portion 3 is determined (S2b), the pressing portion 3 is shaped or selected (S2c). That is, based on the determined size and shape, the pressing portion 3 may be shaped from a predetermined material by 3D printing, casting, or the like. Also, it may be selected from a plurality of pressing portions 3 having at least one different pre-shaped size and shape.

[0064] Once the pressing part 3 is shaped or selected (S2c), the shaped or selected pressing part 3 is temporarily attached to the plate-shaped main body 2 (S2d), and the wearer is asked to try on the relaxation device 1 (S2e). At this time, a plurality of prototypes with pressing parts 3 of various sizes and shapes attached at various positions may be prepared in advance, and one may be selected from the prototypes for wearing. In that case, the step of temporary attachment (S2d) is omitted.

[0065] Then, in the trial fitting (S2e), the wearer is asked to judge whether the wearing feeling is good (S2f). If it is judged to be good, the pressing part 3 is permanently attached (S2g), and the relaxation device 1 equipped with the pressing part 3 is completed. Also, in the above judgment (S2f), if it is judged not to be good, return to the step (S2b) of determining the configuration (one or more of position, size, and shape) of the pressing part 3 on the plate-shaped main body 2, determine the configuration of the pressing part 3 again (S2b), perform the shaping or selection of the pressing part 3 (S2c), the temporary attachment of the pressing part 3 (S2d), the trial fitting of the relaxation device 1 (S2e), and perform the judgment regarding the wearing feeling again (S2f).

[0066] In this way, according to the above embodiment, a relaxation device 1 suitable for the wearer's face can be obtained. In the same manner, the central protrusion 6 can also be configured to suit the wearer's face.

[0067] Note that in the flow shown in FIG. 18, the plate-shaped main body 2 and the pressing part 3 are configured as separate bodies. However, depending on the material selection, the plate-shaped main body 2 and the pressing part 3 can also be integrally shaped. In that case, after determining the configuration of the pressing part 3 (S2b), the plate-shaped main body 2 and the pressing part 3 may be integrally shaped without going through steps S2c to S2h.

Example

[0068] Although it is the relaxation device shown in FIGS. 1 and 2, the device in a state where the pressing part is not provided and the aromatic substance container is not attached was worn by each of three subjects, and a psychological test was conducted. Specifically, after the subject maintained a resting state for 1 minute, the above relaxation device was worn on the face for 5 minutes, and then the subject spent 1 minute in the resting state again. Then, state anxiety was measured by STAI (State-Trait Anxiety Inventory) before and after the trial. The psychological test by the above STAI was conducted under the implementation conditions (questions, judgments, etc.) described in the new version of the STAI manual (published by Jitsumu Kyouiku Publishing). FIG. 19 shows the anxiety scale scores of each subject before and after the trial. Also, when a t-test was performed on the obtained results, p < 0.05 was obtained. Therefore, it was found that the state anxiety was significantly reduced by the visual action of the relaxation device according to the present disclosure.

[0069] As described above, the present invention has been described based on the embodiments, but the present invention is not limited by these embodiments. Also, within the scope described in the claims, various changes, modifications, substitutions, additions, deletions, combinations, etc. are possible, and these also belong to the technical scope of the present invention.
