The present invention relates to a presentation device, a communication system, and a sensitivity presentation method, and more particularly, to a presentation device and a communication system that can be applied to output means in an information device or a communication device.

As a tactile sensation presentation device that presents a tactile sensation to a user, for example, a device described in Japanese Patent Application Laid-Open No. 2001-117715 (Patent Document 1) can be given.
Patent Document 1 discloses a presentation device that presents a haptic sensation to a user by causing a rotator to vibrate and vibrate a sphere held in a vibrating and rotating manner according to a haptic haptic signal. (Presentation device) is described. The presenting device vibrates the moving element, and the vibration of the sphere is transmitted to the user's finger so that the user's finger touches the icon displayed on the screen by the information processing device.

There is also a presentation device that expresses a reaction force obtained from a virtual object based on the strength of vibration.

JP 2001-117715 A

However, the presentation device disclosed in Patent Document 1 has some problems.
As a problem of the presentation device disclosed in Patent Document 1, it is only possible to virtually notify the user of the presence or absence of a virtual contact object (hole or protrusion) by vibration.
Moreover, only the amount of change in the shape of the contact object can be expressed.
These causes are because the vibration of the sphere is simply used as a means for expressing contact with a virtual object. That is, the vibration to be used is controlled only as a means for presenting a physical reaction force. Therefore, when presenting a tactile sensation stimulus, the lack of expressive power given to the user is cited as a problem.
An object of the present invention is to provide a presentation device that presents a tactile force stimulus by vibration to a user and reminds the user of various sensibilities.
Moreover, this invention is providing the communication system which comprised the said presentation apparatus and can transmit the sensitivity which a user wants to transmit.

A presentation device according to the present invention includes a haptic sense presentation unit that presents a haptic stimulus to a user by vibration, and a drive unit that vibrates the haptic sense presentation unit at a predetermined frequency. The tactile sensation presentation unit is vibrated at a frequency corresponding to the sensitivity that the user wants to recall.
The communication system according to the present invention includes the above-described presentation device on the mutual user side, and the frequency for vibrating the haptic sense presentation unit on one user side is based on the sensibility designation to be transmitted from the other user side. It is characterized by controlling.
The sensitivity presentation method according to the present invention provides a vibration of a predetermined frequency associated with a sensitivity that the user wants to recall the haptic stimulus when the haptic stimulus is presented to the user by vibrating the object. The object is presented by being vibrated by a drive unit so as to be given.

ADVANTAGE OF THE INVENTION According to this invention, the presentation apparatus which presents the tactile-force stimulus by a vibration to a user and reminds the user various sensitivity can be provided.
In addition, it is possible to provide a communication system that can transmit the sensitivity that the user wants to transmit to a remote place, including the present presentation device.

Next, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a block diagram illustrating a configuration of a presentation device 1 according to an embodiment.
The presentation apparatus 1 includes a haptic sense presentation unit 10 that presents a haptic stimulus to a user by vibrating, and a drive unit 20 that vibrates the haptic sense presentation unit 10 at a predetermined frequency (presentation frequency). The
The tactile sensation presentation unit 10 only needs to be able to vibrate by simple unevenness, and is configured to maintain vibration at a given frequency (presentation frequency) using a piezoelectric element, vibrator, motor, or the like. Any shape can be used. Further, the haptic sense presentation unit 10 may vibrate the user at a frequency different from the presentation frequency, thereby adding the presentation frequency as a given vibration to the user as a result.
For example, a structure in which the vibration of the piezoelectric element is transmitted through a medium of an incompressible fluid to make the member in contact with the user uneven, or a structure in which the protrusion installed on the tip of the bimorph type piezoelectric element that performs the bending operation is made uneven Etc. can be used.
The drive unit 20 drives the tactile sensation presentation unit 10 to vibrate at a presentation frequency corresponding to the sensibility desired to be recalled by the user.
It is desirable that the drive unit 20 can select a frequency for vibrating the haptic sense presentation unit 10. By selecting the frequency, the drive unit 20 can change the vibration frequency of the haptic sense presentation unit 10 to correspond to a plurality of sensibilities that the user wants to recall.
The presentation frequency may be set based on sensitivity / frequency correspondence data obtained in advance for correspondence between the frequency and the sensitivity that the user wants to recall (gives). In addition, as the presentation frequency, a plurality of types of presentation frequencies can be incorporated into the presentation device in a changeable manner. Further, only one type of presentation frequency may be incorporated in the presentation device according to the purpose of the presentation device 1.
The presentation frequency may be received from an information processing device (not shown) connected to the presentation device 1 with an instruction indicating the sensitivity that the user wants to recall, and the haptic presentation unit 10 may be vibrated according to the instruction. Alternatively, an instruction indicating the frequency may be received and the haptic sense presentation unit 10 may be vibrated according to the instruction.
Moreover, it is also possible to make it possible to input the sensibility that the user wants to recall or the frequency to vibrate to the presentation device 1 without using an information processing device.
Moreover, in order to confirm that the haptic sense presentation unit 10 is vibrating, a detection unit that measures vibration may be provided. Moreover, you may provide the correction | amendment part which controls operation | movement of the drive part 20 based on the measurement data of a detection part, and the sensitivity to be reminded. This confirms whether or not the user is given a desired vibration by contact between the user and the haptic sense presentation unit 10 and can adjust the given vibration by feedback. The detection unit may measure the presence / absence of vibration of the haptic sense presentation unit 10 and the frequency, but may also measure vibration applied from the user's skin or the like. In this way, the vibration of the tactile sensation presentation unit 10 can be adjusted based on the vibration given to the user.
In this way, by driving the tactile sensation presentation unit 10 with a predetermined frequency and frequency waveform corresponding to the sensitivity desired to be recalled by the drive unit 20, it is possible to make the user recall various sensibilities.
It should be noted that if the tactile sensation to be presented is not associated with the sensibility given to the user, it is natural that the predetermined sensibility cannot be recalled. The presentation frequency and the like may be acquired and accumulated in advance according to the sensitivity desired to be provided, and may be mounted as necessary. Further, it may be stored in a server on the Internet or the like, and a presentation frequency or the like corresponding to the sensitivity required may be acquired.
In addition, the frequency (presentation frequency) for vibrating the selected haptic sense presentation unit 10 can be automatically changed at every timing given by the user or the information processing apparatus or with the passage of time. In this way, by using the presentation device 1, it is possible to transmit the sensibility that the user (contactee) wants to give to the user (contactee) while changing it momentarily.
Moreover, if this presentation apparatus 1 is used for communication between users via a communication means, the sensibility that each user wants to transmit and the sensibility felt can be transmitted to the other party. In this case, the communication means may use an electric wire, or may use a communication network such as a LAN or the Internet. For example, it is possible to operate the driving unit 20 of one presentation device 1 from the counterpart device via the communication means. At this time, the notification side may be provided with means for selecting the sensibility to be transmitted and means for automatically acquiring the sensibility currently felt. Moreover, you may provide the means to acquire automatically the sensitivity which wants to convey.
Further, the haptic sense presentation unit 10 may be either a ground type or a non-ground type. Further, energy may be directly applied to the user's body to vibrate. Further, the haptic sense presentation unit 10 may divide a portion where the haptic sense is presented into a plurality of places, such as a pair or a set. For example, if the glove-type tactile sensation presentation unit 10 is used, a vibrating part may be provided on the abdomen of each finger.
Further, the tactile sensation presentation unit 10 and the position positioning technique may be linked. In this way, in the virtual space constituted by the information processing device, the sensitivity received when touching or approaching a person or an object in the virtual space is linked to the position information obtained by positioning the drive unit 20. If moved, various sensibilities can be given to the edible object in the virtual space.

Next, the present invention will be described by way of examples.
FIG. 2 is a block diagram illustrating the configuration of the presentation device according to the first embodiment.
The presentation device shown in FIG. 2 includes a drive unit and a haptic sense presentation unit.
The drive unit selects and sets the sensitivity to be recalled by the user, outputs the sensitivity information a, and the correspondence between the presentation frequency and the sensitivity that is recalled by the user in response to the sensitivity information a is recorded in advance. The frequency setting unit 300 that outputs the frequency data b corresponding to the sensitivity information a with reference to the sensitivity / frequency correspondence data 200, and the drive signal c that receives the frequency data b and is a sine wave at the frequency of the frequency data b The vibration drive part 400 which outputs is included.
The tactile sensation presentation unit is in contact with the user's fingertip, receives the drive signal c, and causes the tactile force to present the tactile sensation to the user by moving the protrusion up and down in a sine wave shape at the frequency of the frequency data b. The sense presentation device 500 is in charge.
Next, the operation will be described.
In order to remind the user of a predetermined sensibility, the sensibility selection unit 100 first selects and sets the sensibility to be recalled by the user, and outputs the sensitivity information a to the frequency setting unit 300. Sensitivity selection / setting may be performed autonomously or in accordance with external input.
Next, the frequency setting unit 300 that has received the sensitivity information a refers to the sensitivity / frequency correspondence data 200 and outputs the frequency data b corresponding to the sensitivity information a to the vibration driving unit 400.
Finally, the vibration drive unit 400 receives the frequency data b and outputs a drive signal c to drive the haptic sense presentation device 500 that is in contact with the user's fingertip at a frequency of the frequency data b. As a result, the presentation device reminds the user of a predetermined sensitivity.
Here, an example of the sensitivity / frequency correspondence data 200 will be described.
FIG. 3 is a result graph in which we obtained a relationship between the sensitivity recalled by the user and the presentation frequency of the haptic sense presentation device 500 through a psychological evaluation experiment. The horizontal axis in FIG. 3 is the presentation frequency. The vertical axis in FIG. 3 represents the seven methods for the subjective assessment items of “biological-mechanical”, “soft-hard”, and “warm-cold”, respectively. Is the evaluation result.
Referring to FIG. 3, it can be read that a sensitivity of “biological, soft, warm” is recalled when the presentation frequency is around 1 Hz to 2 Hz. Further, it can be read that a sensitivity of “mechanical, hard, cold” is recalled at a presentation frequency of about 50 Hz or higher. Moreover, it can be read that neutral sensitivity that is neither of these is recalled in the vicinity of the presentation frequency of 10 Hz.
As described above, the haptic sense presentation unit having a shape capable of reliably transmitting vibration like the haptic sense presentation device 500 presents the haptic sense stimulus in a sinusoidal manner to the user in the above-described frequency band. We have found that “soft, warm” and “mechanical, hard, cold” can be recalled. In addition, this sensitivity is not greatly affected by the intensity of the stimulus as long as it is a stimulus that can be perceived by the user.
As can be seen from the above, for the drive unit adapted to the haptic sense presentation device 500, the sensitivity / frequency correspondence data 200 is preset as the correspondence shown in FIG. 4, as shown in the result graph of FIG. That's fine. As a result, when the sensitivity information a, which is the sensitivity evoked by the user, is “biological, soft, warm”, the frequency data b is set to 1.5 Hz. Similarly, when the sensitivity information a is “mechanical, hard, cold”, the frequency data b is set to 100 Hz. Similarly, when the sensitivity information a is a neutral sensitivity that is neither of these, the frequency data b is set to 10 Hz.
The present presentation device can be applied to, for example, enhancing the sense of reality and attractiveness of various virtual characters displayed on a game machine, an information device, or the like.
As the current state of such virtual characters, various things such as animals, robots, and objects that do not exist in reality are displayed and used. However, the user can perceive a virtual character only with audiovisual information.
Therefore, this embodiment is applied to display a virtual character and present a sine wave stimulus to the user with the haptic sense presentation device 500.
At this time, the frequency of the vibration presented by the haptic sense presentation device 500 is changed according to the characteristics of each virtual character. For example, in the case of an animal, a sinusoidal stimulus may be presented to the user at a frequency of about 1.5 Hz, which reminds the sense of “biological, soft, warm”. Similarly, in the case of a robot, a sine wave stimulus may be presented to the user at about 100 Hz, which recalls the sensitivity of “mechanical, hard, and cold”. Similarly, a sine wave stimulus may be presented to the user at about 10 Hz, which is reminiscent of “neutral sensibility that is neither biological nor mechanical” if the object is unknown. Thus, what is necessary is just to switch the frequency to show according to a character. Moreover, you may switch the frequency to show according to the change of a character.
Thereby, since the user will recall the sensitivity corresponding to each frequency, it is possible to enhance the sense of reality, attractiveness, etc. for each virtual character.
The correspondence between the user's recall and the presented frequency is not limited to that shown in FIG. Further, as is apparent from the evaluation result graph of FIG. 3, the frequencies that recall each sensitivity have a certain range. Therefore, the corresponding frequency may be set within the range. Further, since there are individual differences in sensitivity recall from vibration, a correction unit may be provided, for example, ± 5%, ± 10%, ± 15%, ± 20%, or ± predetermined Hz. Similarly, you may provide a correction | amendment part by the relationship between a tactile-force sense presentation part and a user. Moreover, you may adjust the frequency corresponding to the sensitivity for every site | part which gives a vibration. For example, the drive unit adds or applies a predetermined correction value for each part that receives the user's vibration, and adds or adds another correction value different from the part correction value for each sensitivity to be recalled. You may make it vibrate a force sense presentation part. In addition, a tactile sensation presentation unit and a detection unit that detects vibration applied to the user may be provided. The detection unit may detect the vibration of the tactile sense presentation unit, the vibration of the user, or both. Based on the detection result, the correction unit may add or apply a correction value based on the detection value of the vibration applied to the user to vibrate the haptic sense presentation unit. At this time, the transfer functions of the applied vibration and the vibration may be stored and used for each part or for each frequency (for each sensitivity). Further, the user may be able to adjust the vibration of the tactile sensation presentation unit. A presentation device provided with these correction units and detection units is illustrated in FIG. As described above, by correcting the vibration of the tactile sensation presentation unit from a plurality of different viewpoints, it is possible to appropriately perform correction for each user, for each part, etc., and to present the same sensitivity to everyone. It becomes possible. In addition, the sensibility to be recalled is not limited to the above, and many sensibilities can be expressed by implementing the correspondence between the desired recall sensibility and the presentation frequency or vibration waveform through psychological evaluation experiments or the like.
Further, the part of the stimulus presentation by the haptic sense presentation device 500 is not limited to the fingertip, and may be other body parts such as the palm, the back, the wrist, the whole hand, the neck, and the ear.

Next, an embodiment of a communication system will be described.
FIG. 6 is a block diagram showing a configuration of an embodiment of a communication system using a presentation device.
The communication system shown in FIG. 6 includes both presentation devices via communication means 800. Each presentation device receives an activation switch 600 for instructing the start / presentation of communication by the user, and an ON / OFF signal d from the activation switch 600. In response to the drive instruction signal 700 that outputs the drive command signal e for enabling the operation and the drive command signal e transmitted by the communication means 800, a fixed cycle drive signal f that is a sine wave of a predetermined frequency is obtained. The fixed-period drive unit 900 to be output is in contact with the user's fingertip, receives the fixed-period drive signal f, and raises and lowers the protrusions in a sine wave shape at a predetermined frequency, thereby stimulating the haptic stimulus to the user. And a haptic sense presentation device 500 to be presented. Both presentation devices notify each other of the drive command signal e via the communication partner side and the communication means 800, and transmit the sensibility to remind the other party. The drive command signal e may be a frequency to be oscillated or a sensitivity to be recalled.
In addition, in order to perform communication bidirectionally, each component described above is installed on each side of two users who perform communication. Of course, you may comprise so that sensitivity may be transmitted only to one direction.
Next, the operation will be described.
When the user performs communication, first, the operation switch 600 is turned on, and the drive command signal e is output from the drive instruction unit 700.
Next, the drive command signal e is transmitted by the communication means 800 to the fixed cycle drive unit 900 installed on the communication partner side.
Finally, in response to this drive command signal e, the fixed period drive unit 900 outputs a fixed period drive signal f, and the haptic sense presentation device 500 that is in contact with the user's fingertip is driven with a sine wave at a predetermined frequency. By doing so, haptic communication is performed to the other user.
An object of the communication system of the above-described embodiment is to provide a tactile force sense communication means that can convey the sensibility that the user wants to transmit.
First of all, it is necessary to know what kind of sensibility the user wants to transmit in haptic communication.
In addition, sensitivity / frequency correspondence data may be prepared in accordance with the cultural environment where the user grew up, and a means for enabling selection for each user may be provided. The cultural environment may be selected according to, for example, the language, the country of stay, or a combination thereof. The cultural environment may be collected on a server or the like as collective intelligence via the Internet or the like. In this way, it becomes easy to communicate sensibilities even in different cultural spheres. For example, it can be realized by providing a conversion server that changes the frequency to be presented so as to have the same sensitivity in the communication system when the sensitivity is notified from different cultural spheres. Of course, in the presentation device, data indicating the partner's cultural environment may be received, and the sensitivity received from the partner may be presented at a frequency that matches the sensitivity to be presented to the user.
FIG. 7 is a graph showing the results of our statistical survey and analysis in Japan of the sensibility that the user desires to transmit in so-called skinship communication with tactile sensation. As a result, we have already found that the sensibility that the user most desires to transmit via the communication means is the sensibility that it is “warm”. (See Non-Patent Document 1)
That is, by providing a device in which the sensitivity of “warm” is set as the fixed period, it is possible to provide a powerful haptic communication system that can communicate the sensitivity that the user wants to transmit.
In order to remind the user of the “warm” sensibility, a sine wave haptic stimulus may be presented at a frequency in the vicinity of 1 Hz to 2 Hz, which can be derived from FIGS. 3 and 4 shown in the first embodiment.
Therefore, in this communication system, the predetermined frequency of the fixed period drive signal f is set to 1.5 Hz. Then, while the user turns on the operation switch 600, a tactile force stimulus is presented to the communication partner with a sine wave of 1.5 Hz. As a result, the user on the other end of the communication recalls a “warm” sensitivity.
By performing this operation in both directions, it is possible to communicate with each other to convey the “warm” sensibility that the user wants to transmit.
Of course, the number of the operation switches 600 and the fixed period driving unit 900 may be increased so that the sensitivity of “cold” or “insensitive” can be transmitted and expressed. Moreover, it may replace with the fixed period drive part 900, and the designation | designated period drive part which can selectively designate the frequency which drives the tactile-force sensation presentation device 500 may be provided, and it may be made to express said several sensitivity. At this time, the drive unit may read the sensitivity / frequency correspondence data and determine the frequency to be vibrated. The same may be done when conveying other sensibilities.
Of course, as described above, a correction unit and a detection unit may be provided in combination.
Moreover, the drive part should just vibrate a user's body with a required presentation frequency, and may add a vibration to a user using a frequency different from a presentation frequency. The different frequency here may be any frequency as long as it results in vibration of the user's body at the presentation frequency.
As described above, the presentation device to which the present invention is applied can present the user with tactile sensation stimulation by vibration, and remind the user of various sensibilities.
In addition, since the communication system includes the presenting device, it is possible to transmit the sensitivity that the user wants to transmit to a remote place.
It should be noted that the specific configuration and frequency of the present invention are not limited to the above-described embodiments and examples, and modifications within a range not departing from the gist of the present invention are included in the present invention.
This communication system can be applied to remote communication devices through various communication means such as communication using a mobile phone or chat using a personal computer.
In addition, the presentation device according to the present invention can be used by being incorporated in a mouse, keyboard, touch panel, glasses, writing instrument, wristwatch, robot hand, or the like.
Further, the present invention can be used for a presentation device that expresses sensibility received from a virtual space or augmented reality space using a computer, an object existing in a game, or an object actually existing in a remote place. According to this, it is possible to perceive a non-living object or inorganic substance displayed on a computer as if it is alive and warm. In addition, various sensibility can be given to items in the game, electronically distributed coupons, services provided in the net space, and the like.
