[Structure of the tactile presentation device]
Fig. 1 is a perspective view showing a tactile presentation device 100 according to this embodiment, and Fig. 2 is a cross-sectional view of the tactile presentation device 100. Fig. 1 and Fig. 2 show the tactile presentation device 100 in a state in which it is worn on a user's body S. Fig. 3 is a perspective view of the tactile presentation device 100, and Fig. 4 is a side view of the tactile presentation device 100.

As shown in Figures 3 and 4, the tactile presentation device 100 comprises a support member 101 and a tactile presentation module 102.

The support member 101 fixes the tactile presentation device 100 to the user's body S. The body S can be, for example, the wrist, as shown in FIG. 1. The support member 101 can be wrapped around and fastened to the body S, as shown in FIG. 2, and worn on the body S. In the figure, the inner circumferential side of the surface of the support member 101, i.e., the surface facing the body S, is referred to as the inner circumferential surface 101a, and the outer circumferential side, i.e., the surface opposite the inner circumferential surface 101a, is referred to as the outer circumferential surface 101b.

As shown in Figure 3, the support member 101 is a belt that has a predetermined thickness and stretches in one direction. Hereinafter, the longitudinal direction of the support member 101 is referred to as the X direction, and the lateral direction perpendicular to the X direction is referred to as the Y direction. The thickness direction of the support member 101, perpendicular to the X and Y directions, is referred to as the Z direction.

The size of the support member 101 can be changed as appropriate depending on the part of the body to which it is to be worn, but it is preferable that it has a length that allows it to be wrapped around the body S at least once, as shown in Figure 2. Furthermore, the support member 101 is not limited to a belt, and may be anything that can be worn on the user's body. The support member 101 is provided with an engagement portion to which the tactile presentation module 102 can be fixed. This engagement portion will be described later.

The tactile presentation module 102 is detachable from the support member 101 and generates a tactile sensation. As shown in FIG. 2, the tactile presentation module 102 is disposed on the inner peripheral surface 101a of the support member 101 and contacts the body S. The tactile presentation device 100 may include multiple tactile presentation modules 102 as shown in FIG. 2, or may include a single tactile presentation module 102.

The tactile sensation generated by the tactile presentation module 102 may be any sensation that the user can sense on the skin, and may be one or more of vibration, friction, heating, cooling, etc. Specifically, the tactile presentation module 102 may be a vibration generating module equipped with an eccentric motor or a voice coil motor (VCM), or a pressure presentation module equipped with a bag-shaped inflatable membrane and an airflow generating device that causes air to flow into the inflatable membrane, and capable of presenting pressure.

The tactile presentation module 102 may be a temperature change module that generates or absorbs heat using a Peltier element or the like, or a friction generation module that rotates or slides a member placed against the user's skin. In addition, the tactile presentation module 102 may be any module that can present some kind of tactile sensation that can be perceived by the skin. When the tactile presentation device 100 includes multiple tactile presentation modules 102, each tactile presentation module 102 may be a module of the same type, or may be a module that generates different tactile sensations.

As shown in Fig. 3, the tactile presentation module 102 is arranged on the inner surface 101a along the longitudinal direction (X direction) of the support member 101. As a result, when the support member 101 is wrapped around the user's body S as shown in Fig. 2, it is positioned around the body S.

The tactile presentation device 100 has the above-described configuration. Note that the part on which the tactile presentation device 100 is worn is not limited to the user's wrist. FIG. 5 is a schematic diagram of the tactile presentation device 100 worn on the user's finger. The tactile presentation device 100 may also be worn on any part of the user's body, such as the ankle, toes, torso, or head.

[Adjusting the position of the tactile display module]
The fixed position of the tactile presentation module 102 on the support member 101 can be adjusted. Fig. 6 is a schematic diagram showing the fixed position of the tactile presentation module 102 on the support member 101. As indicated by the arrow in the figure, the tactile presentation module 102 is configured so that its position can be adjusted at least in the longitudinal direction (X direction) of the support member 101.

Although FIG. 6 shows one tactile presentation module 102, the positions of the other tactile presentation modules 102 can also be individually adjusted in the longitudinal direction (X direction) of the support member 101. Furthermore, the tactile presentation module 102 may be configured so that its position can be adjusted not only in the longitudinal direction (X direction) of the support member, but also in the transverse direction (Y direction).

The position of the tactile presentation module 102 relative to the support member 101 can be adjusted by an engagement mechanism using a first engagement portion provided on the support member 101 and a second engagement portion provided on the tactile presentation module 102. Specifically, this can be done by any of the following engagement mechanisms.

<Engagement mechanism using hook-and-loop fastener>
Fig. 7 is a side view of a tactile presentation device 100 equipped with an engagement mechanism using a hook-and-loop fastener, and Fig. 8 is a cross-sectional view thereof. Fig. 9 is a plan view of a support member 101 equipped in the tactile presentation device 100. As shown in these figures, the support member 101 can be equipped with a hook-and-loop fastener 111 as a first engagement portion. The hook-and-loop fastener 111 is provided on the inner circumferential surface 101a along the longitudinal direction (X direction) of the support member 101. The hook-and-loop fastener 111 may be provided over the entire inner circumferential surface 101a, or may be provided in a partial region of the inner circumferential surface 101a, such as a central region in the lateral direction (Y direction).

7 and 8, the tactile presentation module 102 has a hook-and-loop fastener 112 as a second engagement portion. The tactile presentation module 102 can be fixed at any position on the inner circumferential surface 101a by joining the hook-and-loop fastener 112 to the hook-and-loop fastener 111. Although Figs. 7 and 8 show one tactile presentation module 102, the other tactile presentation modules 102 can also be fixed to the support member 101 by the hook-and-loop fastener 112 in a similar manner.

<Engagement mechanism using pins>
Fig. 10 is a side view of a tactile presentation device 100 equipped with an engagement mechanism using a pin, and Fig. 11 is a cross-sectional view thereof. Fig. 12 is a plan view of a support member 101 equipped in the tactile presentation device 100. As shown in these figures, the support member 101 can be equipped with holes 113 as the first engagement portion. A plurality of holes 113 are provided on the inner circumferential surface 101a, and are arranged at predetermined intervals along the longitudinal direction (X direction) of the support member 101.

10 and 11, the tactile presentation module 102 has a pin 114 as a second engagement portion. The tactile presentation module 102 can be fixed at any position on the inner circumferential surface 101a by inserting the pin 114 into one of the holes 113. Although Figs. 10 and 11 show one tactile presentation module 102, the other tactile presentation modules 102 can also be fixed to the support member 101 in a similar manner by insertion of the pin 114 into the hole 113.

<Rail-based engagement mechanism>
Fig. 13 is a side view of a tactile presentation device 100 equipped with an engagement mechanism using a rail, and Fig. 14 is a cross-sectional view thereof. Fig. 15 is a plan view of a support member 101 equipped in the tactile presentation device 100. As shown in these figures, the support member 101 can be equipped with a rail 115 as a first engagement portion. The rail 115 extends along the longitudinal direction (X direction) on the inner circumferential surface 101a. There may be one rail 115 as shown in Figs. 14 and 15, or two or more rails 115 extending along the longitudinal direction (X direction) may be provided.

13 and 14, the tactile presentation module 102 has a protrusion 116 as a second engagement portion. The tactile presentation module 102 can be fixed at any position on the inner circumferential surface 101a by fitting the protrusion 116 into the rail 115 and sliding against the rail 115. Although FIG. 13 shows one tactile presentation module 102, the other tactile presentation modules 102 can also be fixed to the support member 101 in a similar manner by fitting the protrusion 116 into the rail 115.

The engagement mechanism between the tactile presentation module 102 and the support member 101 is not limited to that shown here, but may be any mechanism that allows the tactile presentation module 102 to be fixed at any position in the longitudinal direction (X direction) of the support member 101.

[Effects of tactile presentation device]
The tactile presentation device 100 will be described in comparison with a comparative example. Fig. 16 is a schematic diagram of a tactile presentation device 300 according to the comparative example in a state where it is worn on the body. As shown in Fig. 16(a) and (b), the tactile presentation device 300 includes a support member 301 and a tactile presentation module 302. The tactile presentation module 302 is fixed to the support member 301.

16(a), when the tactile presentation device 300 is attached to the user's body S1, the tactile presentation module 302 is in contact with four points on the top, bottom, left, and right of the body S1. In this state, for example, if it is desired to present tactile sensation only in one direction of the body S1 (e.g., the upper side in the figure), the tactile presentation module 302 located in that direction can be driven.

However, problems arise when the tactile presentation device 300 is worn by another user. Figure 16 (b) shows the state in which the tactile presentation device 300 is worn on the body S2 of another user, where the body S2 is thinner than the body S1. In this case, the contact point of the tactile presentation module 302 with the body S2 is misaligned with the contact point of the tactile presentation module 302 with the body S1. For this reason, even if it is desired to present a tactile sensation in one direction of the body S1 (e.g., upward in the figure), there is a risk that the tactile presentation module 302 is not present in that direction.

For this reason, in the tactile presentation device 300, the contact position of the tactile presentation module 302 varies depending on the body size of the user, and if it is desired to present tactile sensations at spatially separated four points around the wrist for purposes such as giving directional instructions, the presentation position will shift, compromising the effect. It is also difficult to present tactile sensations to a part of the body (for example, the front of the fingers) for purposes such as presenting the sensation of gripping an object.

On the other hand, Figure 17 is a schematic diagram showing the state in which the tactile presentation device 100 is worn on the body. As shown in Figure 17 (a), when the tactile presentation device 100 is worn on the user's body S1, the tactile presentation module 102 is in contact with four points on the top, bottom, left and right of the body S1.

17(b), the tactile presentation device 100 is attached to a body S2 that is thinner than the body S1. As described above, the tactile presentation device 100 is capable of adjusting the position of the tactile presentation module 102 in the longitudinal direction (X direction) of the support member 101, and the tactile presentation module 102 can be fixed at any position.

This allows the tactile presentation module 102 to be positioned to contact four points on the top, bottom, left and right of body S2, just as in the case of body S1, making it possible to bring the tactile presentation module 102 into contact with the desired position regardless of the difference in size between body S1 and body S2.

As described above, in the tactile presentation device 100, the position of the tactile presentation module 102 can be adjusted in the longitudinal direction of the support member 101, making it possible to adjust for deviations in the tactile presentation position that occur due to differences in body size among users.

[About the placement of the tactile presentation module]
The tactile presentation module 102 is disposed on the inner circumferential surface 101a as described above, but the arrangement is not limited to the above.

18, the tactile presentation modules 102 may be arranged over the entire inner peripheral surface 101a. By adjusting the number of tactile presentation modules 102 fixed to the support member 101 according to the size of the body S, it is possible to set the number of tactile presentation modules 102 to a number that exactly surrounds the body S.

19, the tactile presentation module 102 may be arranged only in a portion of the inner surface 101a. If the range of the inner surface 101a where the tactile presentation module 102 is arranged is defined as the "tactile presentation range", the tactile presentation range may be, for example, the pad of the finger or the front of the wrist. Here, by adjusting the position of the tactile presentation module 102 in the longitudinal direction (X direction) of the support member 101, it is possible to set the tactile presentation range to a desired range regardless of the size of the body S.

[About cushioning materials]
The tactile presentation device 100 may further include a cushioning member. Fig. 20 is a cross-sectional view of the tactile presentation device 100 including a cushioning member 103. As shown in the figure, the tactile presentation module 102 is fixed only in a partial range on the inner circumferential surface 101a to form a tactile presentation range.

The cushioning member 103 is a flexible member that suppresses the transmission of tactile stimuli from the support member 101 to the body S. The cushioning member 103 is fixed to the support member 101 in a range of the inner surface 101a other than the tactile presentation range. The cushioning member 103 has an engagement portion (hereinafter, the fourth engagement portion) that can engage with the first engagement portion provided on the support member 101, and the position can be adjusted in the longitudinal direction (X direction) of the support member 101. The fourth engagement portion can be configured in the same way as the second engagement portion (see Figures 7 to 15) provided on the tactile presentation module 102.

The cushioning member 103 may have any structure that suppresses tactile stimulation from the support member 101, and may be made of, for example, urethane rubber or silicone rubber, or may be a bag-shaped member filled with gas or liquid.

In the tactile presentation device 100, in order for the user to recognize the tactile presentation position, it is necessary that the tactile presentation range and other ranges (hereinafter, non-presentation ranges) are spatially separated. For example, when the tactile presentation module 102 performs pressure presentation, when a part of the body S is pressed, the pressure is propagated by the support member 101 to the entire area where the tactile presentation device 100 is attached, so that the body S is also pressed by the support member 101 from the non-presentation range.

In addition, when the tactile presentation module 102 generates vibrations, the vibrations are transmitted through the support member 101, and the body S perceives the vibrations even in the presentation range. This makes it difficult for the body S to perceive the tactile presentation range and non-presentation range as spatially separate.

Here, by providing the cushioning member 103 on the support member 101 in the non-presentation range, the transmission of tactile stimulation from the support member 101 is suppressed, making it possible to separate the tactile presentation range from the non-presentation range and to mitigate the propagation of tactile sensation to areas other than the tactile presentation range. In addition, by using the same engagement mechanism as the tactile presentation module 102 to fix the cushioning member 103 to the support member 101, an engagement mechanism for the cushioning member 103 is not required on the support member 101, and the position of the cushioning member 103 in the longitudinal direction (X direction) of the support member 101 can be adjusted.

In the tactile presentation device 100, the tactile presentation module 102 may function as a cushioning member instead of the cushioning member 103. Specifically, when the tactile presentation module 102 is a pressure presentation module equipped with a bag-shaped inflatable membrane and an airflow generating device that causes air to flow into the membrane, the volume of the inflatable membrane can be kept constant to function as a cushioning member.

[About fastening support members]
As described above, the support member 101 is attached to the body S by being wrapped around the body S and fastened. To fasten the support member 101, the third engaging portion that can be engaged with the first engaging portion described above can be utilized.

21 to 23 are schematic diagrams of a tactile presentation device 100 having a third engagement portion. As shown in Fig. 21, when a hook-and-loop fastener 111 is provided on the inner circumferential surface 101a as the first engagement portion, a hook-and-loop fastener 117 can be provided on the outer circumferential surface 101b as the third engagement portion. By wrapping the support member 101 around the body S and joining the hook-and-loop fastener 117 and the hook-and-loop fastener 111, the support member 101 can be fastened to any length.

22, when a hole 113 is provided on the inner circumferential surface 101a as a first engagement portion, a pin 118 can be provided on the outer circumferential surface 101b as a third engagement portion. By wrapping the support member 101 around the body S and inserting the pin 118 into one of the holes 113, the support member 101 can be fastened to any length.

23, when a rail 115 is provided on the inner circumferential surface 101a as a first engagement portion, a protrusion 119 can be provided on the outer circumferential surface 101b of the support member 101 as a third engagement portion. By wrapping the support member 101 around the body S and fitting the protrusion 119 into the rail 115, the support member 101 can be fastened to any length.

[Providing driving signals to the tactile presentation module]
The electrical connection of the tactile presentation module 102 in the tactile presentation device 100 will be described. Fig. 24 is a schematic diagram showing an electrical connection mechanism in the tactile presentation device 100, and Fig. 25 is an enlarged view of Fig. 24. Fig. 26 is a cross-sectional view showing this electrical connection mechanism. As shown in Fig. 24, the tactile presentation device 100 includes a control circuit 104 and a first electrode 105.

The control circuit 104 generates a drive signal for the tactile presentation module 102 and supplies it to the first electrode 105. The control circuit 104 is connected to wiring 106 (see Figures 1 and 5) and can receive power via the wiring 106. The control circuit 104 can also be connected to an information processing device wirelessly or via the wiring 106 and can receive drive instructions for the tactile presentation module 102 from the information processing device, and can generate a drive signal based on this drive instruction.

The first electrode 105 is provided on the support member 101 and is electrically connected to the control circuit 104. The first electrode 105 is flexible and can be disposed on the bottom surface of a recess provided on the inner circumferential surface 101a as shown in FIG. 26. FIG. 27 is a plan view of the inner circumferential surface 101a showing the first electrode 105. As shown in the figure, the first electrode 105 extends along the longitudinal direction (X direction) of the support member 101 and can be two wires, a ground wire and a signal wire.

26, the tactile presentation module 102 has a second electrode 107. The second electrode 107 is provided so as to protrude and contact the first electrode 105. The second electrode 107 has a built-in spring mechanism, and when the tactile presentation module 102 is fixed to the support member 101, it is pressed by the support member 101, thereby coming into contact with the first electrode 105 and becoming conductive.

28 to 30 are schematic diagrams showing a specific engagement mechanism and electrical connection mechanism of the tactile presentation module 102. As shown in Fig. 28, in the tactile presentation device 100, when the support member 101 and the tactile presentation module 102 are fixed by joining the hook-and-loop fasteners 111 and 112, the first electrode 105 and the second electrode 107 come into contact with each other and become conductive.

29, when the support member 101 and the tactile presentation module 102 are fixed by inserting the pin 114 into the hole 113, the first electrode 105 and the second electrode 107 come into contact and are electrically connected. Furthermore, as shown in FIG 30, when the support member 101 and the tactile presentation module 102 are fixed by engaging the rail 115 with the protrusion 116, the first electrode 105 and the second electrode 107 come into contact and are electrically connected.

The number of first electrodes 105 is not limited to two, and a larger number of first electrodes 105 may be provided depending on the number of tactile presentation modules 102 fixed to the support member 101. By providing a first electrode 105 corresponding to each tactile presentation module 102, it is possible to drive each tactile presentation module 102 individually.

[Use of the tactile presentation device]
