Description

How to set the original signal of vibration in the human skin tactile display device and the human skin tactile display device

The present invention relates to a human skin tactile presentation device and a method for setting a vibration source signal in the human skin tactile presentation device.

In recent years, most electronic devices such as game machines and mobile terminals are equipped with vibration generators used for vibration for notification of incoming calls and receptions and vibration for tactile feedback in games of game machines and apps. There is. For example, Patent Document 1 proposes to mount a vibration device that generates vibrations in two directions on a hard resin operating device in order to give a more realistic tactile sensation in a game machine. Has been done.

Further, Patent Document 2 also proposes a tactile reproduction method in which a reaction force, which is a sensation grasped by a game, is applied to a simulation device such as a game.

However, in the techniques of Patent Documents 1 and 2, vibration and reaction force are applied to a hard device, and the surface of the device is hard. Therefore, when the device is applied to skin reproduction, the user touches the skin. There was little realization that it was, and it was far from reproducing the tactile sensation of the skin.

On the other hand, in Patent Document 3, in order to convey the tactile sensation of a product including a soft product, a tactile sensation reproduction method is a communication tool that prepares an actual product, causes the device to detect it, and transmits the detected tactile sensation by vibration or the like via the device. Has been proposed.

Japanese Patent No. 6253157 Republication of Japan 2017/006670 Japanese Patent No. 4769342

However, in the tactile reproduction according to Patent Document 3, it is a "passive tactile" in which the tactile sensation is perceived by moving the object without moving the finger, but in order to confirm the skin quality by touching and moving the actual skin with the finger. When trying to reproduce the skin quality in Patent Document 3, since the way of touching the fingers is different, a feeling of strangeness occurs in the reproduction of the skin.

In addition, there is a human skin gel that is a sample that imitates human skin as an expression of the texture of the skin, but in order to express various skin conditions, a large number of human skin gels had to be prepared. .. In addition, even if a large number of human skin gels were prepared, there were cases where the skin quality to be expressed was not exactly the same.

Therefore, in view of the above circumstances, the present invention is capable of reproducing an arbitrary skin condition with the same touching method as when actually touching the skin without preparing a large number of human skin gels. The purpose is to provide the device.

In order to solve the above problems, in one aspect of the present invention,
A human skin gel that is provided on a propagating member that propagates vibration and that the subject's finger touches,
A movement speed acquisition unit that acquires the movement speed of the finger on the human skin gel,

A vibration adjusting unit that adjusts the magnitude of the amplitude of the original signal according to the moving speed of the finger.
It is provided with a vibration output unit that converts the adjusted original signal into physical vibration and outputs it, and gives vibration to the human skin gel via the propagation member.
Provided is a human skin tactile presentation device.

According to one aspect, in the human skin tactile sensation presenting device, it is possible to reproduce an arbitrary skin condition in the same way as when actually touching the skin without preparing a large number of human skin gels.

<First Embodiment>
First, the overall configuration of the human skin tactile sensation presenting device 100 according to the first embodiment of the present invention will be described with reference to FIGS. 1 to 3.

FIG. 1 is a side perspective view of the human skin touch presentation device 100 according to the first embodiment of the present invention. As shown in FIG. 1, the human skin tactile presentation device 100 includes a human skin gel 1, a camera 2, a PC 3, an amplifier 4, and a speaker 5.

The human skin gel 1 is a skin model (artificial skin) that imitates a predetermined state of human skin, which is a target to be touched by the finger F of the subject S (see FIG. 3), and has a softness similar to that of human skin. It is an ultra-soft urethane resin to express. For human skin gel 1, for example, Bioskin (registered trademark) (manufactured by Beaulux) is used.

The human skin gel 1 is attached and fixed to the propagation plate (propagation member) 11. The propagation plate 11 is a member that supports the human skin gel 1 and propagates vibration, and is made of, for example, an acrylic plate.

The camera 2 is an example of an imaging device that acquires movement information of the finger F of the subject S (see FIG. 3) on the human skin gel 1. The camera 2 is composed of, for example, Leap Motion (registered trademark), and functions as at least a part of a moving speed acquisition unit. Further, in this configuration, the camera 2 is supported by the camera support 22 above the human skin gel 1 at a position where it does not come into contact with the subject's hand.

The PC (Personal Computer) 3 is an example of an information processing device that is connected to the camera 2 and the amplifier 4 by wire or wirelessly. Based on the position of the finger acquired by the camera 2, the movement speed of the finger is calculated and obtained, and the strength of vibration is output.

Furthermore, the PC3 also has a function of a source signal storage unit that stores the source signal of vibration corresponding to the skin quality (tactile sensation) of human skin. In the following, the original signal is a signal that is a source of vibration for generating vibration by the speakers 5A and 5B, and is a signal in the form of an audio signal that is associated with the skin type. Therefore, the PC 3 outputs to the amplifier 4 information on the strength of the original signal (audio signal) selected according to the skin type to be expressed and the signal intensity corresponding to the moving speed of the finger. That is, the PC3 is a vibration adjusting unit that adjusts the strength (amplitude value) of vibration when outputting vibration according to the original signal set according to the moving speed of the finger.

The amplifier (acoustic amplifier) 4 amplifies the original signal output from the PC 3 according to the intensity information.

The speaker 5 is connected to the amplifier 4 and is configured as a pair of left and right speakers 5A and 5B. The speakers 5A and 5B are vibration output units that convert the adjusted audio signal into physical vibration and output it, and vibrate the human skin gel 1 via the propagation plate 11. The speakers 5A and 5B are connected to the amplifier 4 by wire or wirelessly. Further, the speakers 5A and 5B are in contact with the propagation plate 11 of the device pedestal of the human skin gel 1 and are sandwiched so as to propagate the vibration to support the propagation plate 11. The structure of the device pedestal that supports the speakers 5A and 5B and the human skin gel 1 will be described below together with FIG.

FIG. 2 is a front view of the human skin touch presentation device 100 of FIG. In FIG. 2, the PC 3 and the amplifier 4 are not shown.

As shown in FIGS. 1 and 2, the camera 2 is attached to the camera support 22 via the camera fixing portion 21.

Further, as a device pedestal for supporting the human skin gel 1 and the speakers 5A and 5B, a propagation plate 11 which is an upper acrylic plate, a fixing plate 12 which is a lower acrylic plate, a base 13, and a cushioning material 14 are provided. There is. The human skin gel 1 is attached to the propagation plate 11 which is the upper acrylic plate, and the vibration is propagated.

The speakers 5A and 5B have a circular diaphragm 51 in which physical vibration is generated, a frame 52 which is a frame surrounding the diaphragm 51, and a housing 53 to which the frame 52 is mounted.

Further, slits 54 (54A, 54B) that are notched from the surfaces of the diaphragm 51 and the frame 52, which generate vibration, are formed in the center of the facing surfaces of the speakers 5A and 5B in the vertical direction. Has been done. The propagation plate 11 to which the human skin gel 1 was attached was inserted into the slits 54A and 54B, and the speakers 5A and 5B were sandwiched between the diaphragms 51 from the left and right, so that the transmission plate 11 was generated. The vibration propagates to the propagation plate 11.

Further, the lower surface of the housing 53 of the speakers 5A and 5B is fixed to the upper surface of the fixing plate 12 which is the lower acrylic plate.

In the device pedestal, the lower surface of the lower fixing plate 12 is attached to the upper surface of the base 13 via the cushioning material 14. Since the vibrations of the speakers 5A and 5B are not propagated to the base 13 due to the cushioning material 14, even if the human skin tactile presentation device 100 is installed on the desk D (see FIG. 3), the vibrations on the surface of the desk D. Is not propagated and is less likely to be scratched.

Further, since the camera support column 22 is fixed to the lower fixing plate 12 and / and the base 13, the shooting range of the camera 2 can be fixed around the human skin gel 1.

FIG. 3 is a schematic view showing the human skin touch to the subject S by the human skin touch presentation device 100 according to the first embodiment of the present invention.

As shown in FIG. 3, the subject S brings the pad of the finger F into contact with the human skin gel 1 and moves (slides) the finger F on the human skin gel 1. Then, the human skin tactile sensation presenting device 100 gives a tactile sensation when the finger is slid.

For example, the beauty advisor selects and sets the source signal of vibration so that the subject (customer) can reproduce the feel of the bare skin or the feel of the skin after application of cosmetics, beauty agents, oils, etc. Then, vibration is presented to the subject's finger.

For example, in order to reproduce the normal skin condition, the desired skin condition, and the like, the human skin tactile presentation device 100 acquires the original signal, which is the original data of the vibration corresponding to a plurality of skins, in advance in the PC3. I will remember it.

Then, as the function of the PC3 to be operated, it has a function of operating so as to select the skin condition of the bare skin to be reproduced on the human skin gel, and a function of selecting the original signal based on the selection of the skin condition. ing.

For example, the original signal stored in the memory 302 of the PC 3 (see FIG. 4) is assigned a name, a code, a property, etc. for each signal, and the display unit 308 displays the name corresponding to the signal. Then, by operating the input unit 307, the original signal used for the vibration presentation at that time is selected.

Specifically, when the subject S wants to reproduce the tactile sensation of the bare skin, the PC3 causes the display unit 308 to display a screen for selecting a plurality of types of cosmetics, and causes the subject S to reproduce the skin condition of the bare skin. The selection is made via the input unit 307, which is the skin condition selection unit. As shown in Table 1, the PC 3 stores the original signal of the vibration associated with the skin condition of the bare skin, and selects the original signal according to the cosmetics selected by the input unit 307.

Further, the human skin tactile presentation device 100 of the present invention can reproduce not only the tactile sensation of bare skin but also the tactile sensation of applying something to the skin.

When the subject S wants to reproduce the tactile sensation in the applied state of cosmetics (cosmetics) or the like, first, the reference solution R is dropped onto the human skin gel 1. Then, the PC 3 causes the display unit 308 to display a screen for selecting a plurality of types of cosmetics, and the cosmetic selection unit determines the skin condition of the subject S with a specific cosmetic to be reproduced as a tactile sensation. The selection is made via the input unit 307. As shown in Table 2, the PC3 stores the original signals corresponding to the vibrations associated with the skin condition when a plurality of types of cosmetics are applied, and selects the cosmetics selected by the input unit 307. Select the source signal accordingly.

In addition, even if the same cosmetics are applied, the tactile sensation of the skin changes depending on the condition of the bare skin, so the original signal is used to reproduce the skin condition when the prescribed cosmetics are applied in consideration of the condition of the bare skin. May be subdivided and prepared.

The method of acquiring the original vibration signal for reproducing the condition of the bare skin and the condition of the skin when the cosmetic is applied on the human skin gel will be described with reference to FIGS. 6 to 9C.

FIG. 4 is a block diagram of the human skin tactile sensation presenting device 100 according to the first embodiment of the present invention.
The PC 3 includes a USB interface 301, a memory 302, an operation system (OS) 303, a sound controller 304, an audio equipment connection unit 305, a system bus 306, an input unit 307, a display unit 308, and the like. There is. The input unit 307 is a mouse, a keyboard, a touch pad, a touch panel input surface, etc., and the display unit 308 is an LCD (liquid crystal display), an organic EL display, or the like.

The USB interface 301, the memory 302, the operation system 303, the sound controller 304, the audio equipment connection unit 305, the input unit 307, and the display unit 308 are connected via the system bus 306. Alternatively, when the PC 3 is a desktop personal computer, the input unit 307 and the display unit 308 may be provided as separate bodies so as to be connected to the main body by the USB interface 301.

The USB interface 301 receives the finger position information captured by the camera 2.

The memory 302 stores in advance the original signal, which is an audio signal that is the source of vibration according to the human skin, as the original signal storage unit.

The operation system (OS) 303 has, for example, a CPU (Central Processing Unit) 331, an FPGA (Field-Programmable Gate Array) 332, a RAM (Random Access Memory) 333, a ROM (Read Only Memory) 333, and the like. The CPU 331 and the FPGA 332 use the RAM 333 as a work area to execute various control programs stored in the ROM 334, and output control commands for controlling various operations in the PC 3.

In the OS 303, for example, the CPU 331 is a movement speed calculation unit that calculates the speed of finger movement based on the image of the finger position taken by the camera 2. Specifically, for example, a library associated with the camera 2, for example, Leap Motion (registered trademark) P5 is used to detect the movement of the finger, and the movement speed of the finger is calculated by time differentiation. Further, the FPGA 332 calls the original signal stored in the memory 302.

The sound controller 304 adjusts the volume of the called original signal (voice signal) according to the movement of the finger. For example, it is adjusted so that it does not vibrate while the finger is stationary, but vibrates after the finger starts to move, and outputs an audio signal whose amplitude increases as the movement speed increases.

The audio device connection unit 305 is a terminal for connecting to the amplifier 4, and outputs an audio signal adjusted by the sound controller 304 to the amplifier 4.

The sound controller 304 and the audio equipment connection unit 305 function as a vibration adjustment unit that outputs the adjustment value of the amplitude of the waveform of the original signal and the original signal which is the movement speed of the finger and the voice signal.

FIG. 5 is a control sequence diagram of the human skin touch presentation device 100 according to the first embodiment of the present invention.

First, as a preparation before presentation, subject S selects the skin type to be reproduced for PC3 (S101), and the original signal (FIG.) corresponding to the selected skin type to be presented at the time of tactile presentation on PC3. 6 to 9C, which will be described later), are called in the PC3 (step S102).

Then, when the subject S touches the human skin gel 1 with the finger F (S103), the camera 2 detects the position of the finger on the human skin gel 1 (S104) and outputs the finger position data to the PC3. ..

The PC3 outputs the original signal (audio signal) and the amplitude adjustment instruction of the original signal based on the finger position data. Specifically, in S105, the PC 3 detects the movement speed of the finger from the position of the finger based on the information received from the camera 2, adjusts the volume according to the movement, and adjusts the audio signal to the amplifier 4. The audio signal of the instructed volume) is output (S106).

In S107, the amplifier 4 amplifies the original signal (audio signal) with the intensity set in association with the movement of the finger, and outputs the amplified audio signal to the speakers 5A and 5B.

Speakers 5A and 5B exhibit vibration in S108. At this time, the vibration is presented only when the finger moves. The faster the movement, the larger the amplitude. Due to this vibration presentation, vibration is presented to the human skin gel 1 via the propagation plate 11 (S109), and when the subject senses the vibration with the finger F on the human skin gel 1 via the propagation plate 11 (S110). , Produces a more natural texture.

<Pre-setting of original signal>
Next, a method of acquiring the original signal in the human skin tactile sensation presenting device 100 according to the first embodiment will be described with reference to FIGS. 6 to 9C.

FIG. 6 is a flowchart illustrating a procedure for setting the original signal in the human skin tactile sensation presenting device 100 according to the first embodiment of the present invention. 7A and 7B are measurement diagrams when measuring vibration data on human skin and on human skin gel using acceleration in the setting procedure of the original signal of FIG. FIG. 8 is an example of vibration data actually measured on human skin using an acceleration sensor. 9A to 9C are graphs obtained by converting the measured vibration data into a frequency distribution via voice data. In the preset setting of the original signal, the original signal finally set will be an audio signal, and the audio signal in the middle stage will be described as audio data.

The setting procedure shown in FIG. 6 is a part of a preparatory step in which the human skin tactile sensation presenting device 100 prepares in advance before presenting the tactile sensation to the subject as shown in FIGS. 3 and 11.

FIG. 7A shows the state when the vibration data is acquired on the human skin H in step S901, and FIG. 7B shows the state when the vibration data is acquired on the human skin gel 10 in S904 and S909. The information processing device used to set the original signal may be the same as or different from the PC3 shown in FIG. However, in order to ensure consistency in frequency characteristics and the like, it is preferable to use the amplifier 4, the speakers 5A and 5B, the human skin gel 1, the propagation plate 11, and the like included in the human skin touch presenting device 100.

First, in S901, the acceleration sensor A is attached to the fingernail of the sample provider, and the vibration data when touching the human skin is acquired as an actually measured value. The state of the measurement in S901 is shown in FIG. 7A.

As shown in FIG. 7A, the acceleration sensor A installed on the fingernail collects vibration data (sample data) by touching the skin (human skin) H of the human arm while moving. In this example, a high-precision acceleration sensor (A3AX-SENSOR, AX2609B-01, manufactured by TecGihan) was used as the acceleration sensor A.

Specifically, with the accelerometer A attached to the tip of the middle finger, we traced the real "rough skin", one of the sample providers. As shown in FIG. 7A, the area to be traced is a sample of 50 mm × 20 mm where the downy hair on the outside of the left forearm grows, and the finger F is moved so as to move in one direction in 4 seconds, and the vibration data during the tracing. Was acquired.

As shown in FIG. 7A, FIG. 8 shows an example of vibration data actually measured using an acceleration sensor on the human skin H. With the acceleration sensor A, data vibrations in the three directions of X, Y, and Z shown in FIG. 7A can be obtained. In FIG. 8, the horizontal axis represents time [seconds] and the vertical axis represents acceleration [g (G)]. Here, due to the viscoelasticity of the fingertip skin, it is considered that the vibration data in the shear direction is suitable for tactile presentation this time, and the horizontal acceleration data (vibration data in the X direction) is converted into voice data in S902 below. The vibration data to be used is used.

Then, in S902, the information processing apparatus incorporates the sample data (acceleration data in the X direction (measured value of vibration data)) acquired in S901 into audio software (for example, Audacity®) and voice data (measured value). ).

In S903, the frequency distribution of the vibration data of the measured value is calculated. Specifically, the frequency characteristic graph is generated by Fourier transforming the voice data generated in S902. FIG. 9A is a frequency characteristic graph showing a frequency distribution (measured value) obtained by Fourier transforming the voice data converted from the vibration data of the measured value. In FIGS. 9A to 9C, the horizontal axis shows the frequency (Hz) and the vertical axis shows the amplification degree (dB).

In S904, the measured audio data is given to the amplifier 4, played back by the speakers 5A and 5B, and the human skin gel 1 is vibrated at the same speed as when the human skin gel 1 is touched. The vibration data when the acceleration sensor A is attached to the fingernail at the same distance and touched is acquired as a reproduced value. The state of measurement in S904 is shown in FIG. 7B.

In S905, the vibration data of the reproduced value acquired in S904 is taken into the audio software by the information processing device and converted into the voice data of the reproduced value.

In S906, the frequency distribution is calculated by performing a Fourier transform on the voice data of S905 converted from the vibration data of the reproduced value. FIG. 9B is a frequency characteristic graph showing a frequency distribution (reproduced value) obtained by Fourier transforming the voice data converted from the vibration data of the reproduced value generated in S104 in the information processing apparatus.

In S907, the equalizer (frequency adjustment filter) is designed based on the difference between the frequency distribution (actual measurement value) generated in S903 and the frequency distribution (reproduced value) generated in S906. Specifically, ideally, it is desirable that these two frequency distributions match, but different results will be obtained depending on the filter characteristics of the amplifier 4 and speakers 5A and 5B included during playback, and the characteristics of the human skin gel 1. .. In order to correct this, an equalizer in increments of 10 Hz was created in this example by the amplitude ratios of FIGS. 9A and 9B (differences in dB display). This equalizer matches the difference between "frequency distribution when in direct contact with the skin" and "frequency distribution when a signal is sent to the amplifier and vibration is presented to the skin through the speaker, propagation plate, and human skin gel". Acts as an inverse filter.

For example, when reproducing the original signal (audio waveform) of the recorded vibration, it is basically low due to the characteristics of the speakers 5A and 5B and the amplifier 4, and the attenuation caused by feeling the vibration via the human skin gel 1. A pass-through filter is applied, and it changes from the tactile sensation you want to feel. In order to correct this, a reverse filter, that is, a filter that enhances the high frequency side to some extent is applied to bring the tactile sensation on the human skin gel 1 closer to the tactile sensation of the real skin.

Then, in S908, the voice data (measured value) calculated in S902 is corrected by applying the equalizer (inverse filter) created in S907 to create voice data (correction value).

After that, for confirmation, in S909, the voice data (correction value) created in S908 is input to the amplifier 4, and the final value of the vibration data is acquired by the acceleration sensor A provided on the fingernail on the human skin gel 1. To do. The state of measurement in S909 is shown in FIG. 7B.

In S910, the final value of the vibration data is converted into voice data (final value), and in S911, the voice data (final value) is Fourier-transformed again to calculate the frequency distribution (final value). FIG. 9C is a frequency characteristic graph showing a frequency distribution (final value) obtained by Fourier transforming the voice data (final value) converted from the vibration data of the final value generated in S911 in the information processing apparatus.

In S912, the frequency distribution (actual measurement value) created in S903 and the frequency distribution (final value) created in S911 are compared and confirmed. In this example, the waveform in FIG. 9C is relatively consistent with the waveform in FIG. 9A, suggesting that the equalizer worked correctly.

In S912, the frequency distribution (actual measurement value) and the frequency distribution (final value) are compared, and if the matching rate is low, the equalizer step set in S907 is changed, or the data by the acceleration sensor A is used. It is preferable to adjust so that the measured value on the human skin H and the vibration frequency of the final value on the human skin gel 1 are substantially matched by retaking.

Then, if there is no problem in the confirmation in S912, the voice data (correction value) created in S908 in S913 is set as the original signal in the voice signal format according to the human skin before amplification, and the source of the PC3. It is stored in the memory 302 which is a signal storage unit.

By collecting samples in advance using actual human skin and setting the source signal of vibration in this way, the human skin tactile presentation device of the present invention can actually be used without preparing a large number of human skin gels. Any skin condition can be reproduced with the same touching method as when touching the skin.

The graphs of FIGS. 8 and 9A to 9C are examples of a sample of "rough skin" with one sample provider (n = 1), but by increasing the number of sample providers, The reliability of the vibration source signal can be further improved. Furthermore, by collecting people with different skin types as sample providers or by collecting samples of different ages and genders, it is possible to increase the types of skin presented by the human skin tactile presentation device of the present invention.

<Second Embodiment>
Next, the human skin tactile sensation presenting device 200 of the second embodiment will be described with reference to FIGS. 10 to 14.

FIG. 10 is a side perspective view of the human skin tactile sensation presenting device 200 according to the second embodiment of the present invention. FIG. 11 is a schematic view showing the human skin touch to the subject S by the human skin touch presenting device 200 according to the second embodiment of the present invention.

The human skin tactile presentation device 200 of the present embodiment includes a human skin gel 10, a slide volume 6, a microcontroller 7, a switch 75, and a motor driver IC 8.

As shown in FIGS. 10 and 11, the slide volume 6 is arranged on the front side close to the subject S with respect to the human skin gel 10.

The slide volume 6 is a movement speed acquisition unit that acquires the movement speed of the finger on the human skin gel 10, and adds resistance to the movement (brake) when the finger moves in the lateral direction (rail extension direction). Or, it also functions as a finger movement assisting unit that assists (accelerates) movement.

The microcontroller 7 is configured by combining one IC (Integrated Circuit) or a circuit on an electronic board, for example, calculates the movement speed of a finger, and calculates the movement speed of a finger, and uses resistance / acceleration data to obtain 1 for each time according to the movement speed. By selecting a control value, it is output to the motor driver IC 8 so as to adjust the resistance or propulsion acceleration (slide tactile sensation) of the motor 63 (see FIG. 12) of the slide volume 6.

Note that the load resistance and propulsion acceleration given to the slider 64 (ring 66) on the rail 61 may be collectively referred to as the slide tactile sensation. Then, the original data of the slide tactile sensation that generates resistance / acceleration stored in the microcontroller 7 is called a slide tactile sensation signal.

The motor driver IC 8 is a part of the finger movement control unit that controls the motor 63 (see FIG. 11) of the slide volume 6 so as to give the finger on the human skin gel 10 a human skin feel.

In the present embodiment, the human skin tactile presentation device 200 stores slide tactile signals corresponding to a plurality of skins in order to reproduce a normal skin condition, a desired skin condition, and the like, and for example, a switch 75 is pressed. It is preferable that the microcontroller 7 can output a slide tactile signal corresponding to any skin by operating it or remotely controlling it from a smartphone or the like.

That is, the microcontroller 7 has a function of selecting a slide tactile signal based on the skin type selection information set by the switch 75.

For example, the original signal stored in the memory 701 (see FIG. 13) of the microcontroller 7 is assigned a name, a code, a property, etc. for each signal, and by operating the switch 75, the slide of that time is performed. The slide tactile signal used for tactile presentation is selected.

Subject S selects a specific skin condition of the bare skin by operating the switch 75 when he / she wants to reproduce the tactile sensation of the bare skin. The microcontroller 7 stores the slide tactile signals corresponding to the slide tactile sensations associated with a plurality of types of bare skin, and selects the slide tactile sensation signals according to the bare skin selected by the switch 75.

Subject S drops the reference solution R onto the human skin gel when he / she wants to reproduce the tactile sensation of the applied state of cosmetics or the like. Then, the subject S selects a skin condition to which a specific cosmetic is applied by operating the switch 75. The microcontroller 7 stores a slide tactile signal corresponding to the slide tactile sensation associated with the skin condition when a plurality of types of cosmetics are applied, and slides according to the cosmetics selected by the switch 75. Select a tactile signal.

In addition, even if the same cosmetic is applied, the tactile sensation of the skin changes depending on the condition of the bare skin, so a slide tactile signal that takes into consideration the condition of the bare skin and reproduces the skin condition when a predetermined cosmetic is applied. May be subdivided and prepared.

An example of a slide tactile signal for reproducing the state of bare skin and the state of the skin when a cosmetic is applied on the human skin gel 10 will be described later together with FIGS. 15A to 15C.

FIG. 12 is a front view illustrating the arrangement of the slide volume 6 and the human skin gel 10 in the human skin touch presentation device 200.

As shown in FIG. 12, the slide volume 6 has a rail 61, a support frame 62 for supporting the rail 61, a motor 63, a slider 64 which is an operation terminal for the rail 61, and a variable resistor 65. A ring 66, which serves as an annular operation knob, is attached to the 64.

As shown in FIG. 12, the variable resistor 65 has terminals 651 and 652 at both ends of the rail 61 and movable terminals 653 associated with the positions of the slider 64, and corresponds to the position of the slider 64 with respect to the rail 61. The resistance value changes according to the position of the movable terminal 653.

Further, the slide volume 6 is a motor-driven slide volume that gives a slide tactile sensation by applying a load (decelerating) or accelerating (promoting movement) the movement of the slider 64 on the rail 61 by the motor 63. Is.

Subject S touches the human skin gel 10, which is a skin model, with the finger F inserted into the ring 66. When the finger pad of the fingertip is moved to the left or right along the human skin gel 10, the base of the finger F comes into contact with the ring 66, and the ring 66 also moves together. At that time, as the slider 64 moves on the rail 61, the resistance value of the variable resistor 65 attached to the slider 61 changes. The position and moving speed of the finger can be calculated by reading the change in the resistance value by the microcontroller 7 in the subsequent stage.

Since the present embodiment is premised on moving the fingertips of the subject to the left and right, it is preferable that the human skin gel 10 is provided long in the left and right direction. In this example, the human skin gel 10 is attached to the entire upper surface of the propagation plate 11 which is the upper acrylic plate.

Further, in the present embodiment, the position of the inner peripheral surface of the ring 66 of the slide volume 6 is substantially the same as that of the human skin gel 10 with which the fingertips come into contact in the vertical direction, or slightly above the position of the human skin gel 10. Arranged like this. Therefore, the lower surface of the slide volume 6 is fixed to the upper surface of the fixing plate 12 which is the lower acrylic plate.

Further, in the present embodiment, since the speaker is not provided, the upper acrylic plate 11 to which the human skin gel 10 is attached is supported by being sandwiched between the support side plates 15A and 15B, and the support side plates 15A, 15B is fixed to the fixing plate 12 which is the lower acrylic plate.

The lower surface of the fixing plate 12, which is the lower acrylic plate, is attached to the upper surface of the base 13.

In the present embodiment, the lower surface of the base 13 prevents the slide volume 6 from being displaced in the left-right direction with respect to the desk so that the support frame 62 on the rail 61 side of the slide volume 6 does not move when the ring 66 moves left and right. Non-slip 16A and 16B are provided.

FIG. 13 is a block diagram of the human skin tactile sensation presenting device 200 according to the second embodiment of the present invention.
In this configuration, the microcontroller 7 has a memory 701, a first ASIC 702, a second ASIC 703, a connection terminal 704, and the like.

The memory 701 is a slide tactile signal storage unit that stores resistance / acceleration data corresponding to friction and smoothness of human skin, that is, slide tactile signals corresponding to lateral skin reproduction data.

The first ASIC 702 reads the change in the voltage value of the motor 63 of the slide volume 6, and calculates the speed at which the finger moves in the left-right direction from the time derivative of the position indicated by the motor 63. Then, the ASIC 702 selects a control value in the slide tactile signal according to the movement speed of the finger, and adjusts the resistance or acceleration of the motor 63 which is a finger movement assisting portion, thereby rubbing the finger on the human skin gel 10. Gives a smooth and smooth feel to the human skin. The ASIC 702 functions as a part of the auxiliary operation control unit.

The second ASIC703 functions as a slide tactile signal selection unit that reads the selection information on the switch 75, selects and outputs the slide tactile signal associated with the selection information.

The connection terminal 704 is a terminal for connecting the microcontroller 7 to the slide volume 6, the switch 75, and the motor driver IC 8.

FIG. 14 is a sequence diagram of the human skin tactile sensation presenting device 200 according to the second embodiment of the present invention. The sequence in the human skin tactile sensation presenting device 200 will be described with reference to FIG.

First, as a preliminary preparation, the subject S selects the skin type to be reproduced for the switch 75 (S201), the microcontroller 7 reads the selection information on the switch 75 (S202), and the microcontroller 7 is selected. A slide tactile signal (see FIGS. 15A to 15C) corresponding to the skin type is called (S203).

In S204, when the finger F of the subject S touches the human skin gel 10 and the finger F moves, the ring 66 attached to the slider 64 of the slide volume 6 also moves (S205).

In S206, the resistance value of the variable resistor 65 of the slide volume 6 changes according to the position of the ring 66 in S205. That is, in S204 to S206, the slide volume 6 outputs information on the time change of the finger position. At this time, for example, the position of the finger is sampled every 1 kHz.

In S207, the microcontroller 7 reads the change in the resistance value of the variable resistor 65 of the slide volume 6, and in S208, the finger movement speed is calculated from the time derivative of the position.

Then, in S209, the microcontroller 7 instructs the motor driver IC8 by selecting a value that reflects the moving speed of the finger from the slide tactile signal so as to give a predetermined load resistance or acceleration.

In S210, the motor driver IC8 controls the motor 63 of the slide volume 6 according to the load resistance or acceleration instructed in S207.

Then, in S211, the motor 63 presents the adjusted regulation (load) or acceleration to the moving finger, and in S212, the subject feels friction when tracing the skin from the load or acceleration of the slide volume 6. And sense smoothness.

Here, FIGS. 15A to 15C show examples of slide tactile signals according to the skin type, which are called and set in S203 and output in S209 to S211. FIG. 15A is an example of setting a slide tactile signal corresponding to rough skin, FIG. 15B is an example of setting a slide tactile signal corresponding to smooth skin, and FIG. 15C is an example of setting a slide tactile signal of sticky skin. ..

FIG. 15A is an example of tactile sensation setting corresponding to the bare skin of rough skin, and the horizontal axis shows the speed of the finger and the vertical axis shows the load resistance. In this example, when the moving speed is smaller than a certain threshold value, the finger is judged to be "resting" and the static frictional force is presented. Specifically, the position control is performed so that the finger is returned to the original position. Then, when the speed at which the finger moves exceeds a certain threshold value, it is determined as "movement" and a constant frictional force is presented. The frictional force presented here specifically presents a constant reaction force that does not depend on the speed.

FIG. 15B is an example of tactile sensation setting corresponding to the bare skin of smooth skin, and the horizontal axis shows the speed of the finger and the vertical axis shows the propulsion acceleration. In this example, when the speed at which the finger moves exceeds a certain threshold value, a force (propulsion acceleration) that pushes the finger in the direction of the speed is applied. As a result, the finger feels as if it slides more smoothly, and the human skin gel 10, which is the object, gives a feeling as if it becomes smoother.

15A and 15B show examples of slide tactile data that reproduces bare skin, but in this configuration, it is also possible to show the state after applying cosmetics, beauty essence, oil, etc. to the skin. Is.

FIG. 15C shows an example of tactile setting that reproduces the state of sticky skin after applying a highly viscous cosmetic such as oil or ointment to the skin (for example, smooth skin). Shown. In FIG. 15C, the horizontal axis represents the speed of the finger and the vertical axis represents the load resistance. In this example, "viscosity" is exhibited by presenting a reaction force proportional to the velocity. For example, the reaction force is increased by changing the voltage applied to the motor 63, which is a general motor control method, or changing the pulse ratio of the PWM (Pulse Width Modulation) pulse applied to the motor 63.

As an example of viscous skin, in the above example, stickiness when an ointment-like coating applied to the skin is applied has been described, but even when the coating is not applied, it occurs when the body is in a bad condition. Even when expressing the skin condition in which highly viscous sticky sweat covers the skin, the slide tactile sensation can be expressed by the reaction force exhibiting "viscosity" as shown in FIG. 15C.

Here, when the microcontroller 7 gives an instruction to the motor driver IC8 in S209 of FIG. 14, for example, when the slide tactile sensation as shown in FIG. 15A is output, the load resistance is not changed regardless of the speed. The load resistance of any one of the two values is output only by comparing with the speed threshold value.

On the other hand, when the slide tactile sensation as shown in FIGS. 15B and 15C is output, the propulsion acceleration and the load resistance change according to the speed, so that the propulsion corresponds to the finger movement speed calculated by differentiating the position. Values corresponding to acceleration and load resistance are extracted and reflected in a graph in real time for output.

In the above example, as the slide tactile signal expressing one skin type, the load resistance is used in FIGS. 15A and 15C, and the propulsion acceleration is used in FIG. 15B, but one skin type is expressed. As the slide tactile sensation, a signal that gives both load resistance and propulsion acceleration may be set with the velocity threshold as a boundary.

The PC 30 outputs information on the skin quality with the type of cosmetic selected from the plurality of types of cosmetics to the microcontroller 7.

Although the PC30 stores the correlation tables as shown in Tables 1 and 2 described above, which associate the skin condition with the original signal that is the source of vibration, the correlation between the skin condition and the slide tactile signal is stored. The table is stored in the microcontroller 7.

In addition, the digital potentiometer 9 adjusts the magnitude of voice data. In the present embodiment, the digital potentiometer 9 functions as a vibration adjusting unit that adjusts the strength (amplitude width) of vibration when outputting the original signal (voice signal) according to the moving speed of the finger.

That is, in S305 to S307, the slide volume 6 outputs information on the time change of the finger position. At this time, for example, the position of the finger is sampled every 1 kHz.

In S308, the microcontroller 7 reads the change in the resistance value of the variable resistor 65, and in S307, calculates the speed of the finger from the time derivative of the position.

The finger speed information calculated in S310 is output to the digital potentiometer 9.

In S311 the digital potentiometer 9 adjusts the volume according to the original signal and the speed of the finger instructed in S302, and outputs the volume to the amplifier 4.

Then, in S312, the amplifier 4 outputs the amplified audio signal of the called original signal at the set volume.

In S313, the speakers 5A and 5B output the amplified audio signal as physical vibration. At this time, the subject S senses the vibration to the finger F by exhibiting the vibration only when the finger moves.
