First Embodiment
Hereinafter, a first embodiment of the present invention will be described based on the drawings. FIG. 1 is a diagram illustrating a configuration example of a vibration device according to the first embodiment. The vibration device 100 according to the first embodiment is for presenting vibration to a target site around the scapula and around the clavicle.

  Specifically, as shown in FIG. 1, in the vibration device 100 according to the first embodiment, the vibration imparting body 11 for giving vibration to a target site, and the vibration presenting portion in which the vibration imparting body 11 is installed 12 and a contact mechanism 13 for bringing the vibration presenting unit 12 into contact with the target site. The vibration imparting body 11 is connected to a vibration source PL that supplies a vibration signal via a code CD.

  The vibration device 100 is provided with two sets of the vibration applying body 11 and the vibration presenting unit 12. The contact mechanism 13 is for bringing the two vibration presenting units 12 into contact with the target portion. In the first embodiment, the contact mechanism 13 is for bringing the two vibration presentation units 12 into contact with the target site around the shoulder blade and around the clavicle of the user, and the two vibration presentation units 12 And an elastic suspension member which is suspended while bending between the two.

  In the example of FIG. 1, the suspension member of the contact mechanism 13 has a substantially U-shape. Here, the distance between the two vibration presenting units 12 is slightly smaller than, for example, a length (body thickness) obtained by connecting a portion around the scapula and a portion around the clavicle with a horizontal straight line on the basis of an adult having a standard body shape. It is preferable to design to a certain extent (hereinafter referred to as a steady interval). Further, the contact mechanism 13 is preferably configured to be able to expand and contract its length.

  In the steady state where external pressure is not applied to the contact mechanism 13, the interval between the two vibration presenting units 12 is stable at the steady interval. On the other hand, when external pressure is applied to the contact mechanism 13 in the direction in which the distance between the two vibration presenting parts 12 is narrowed or in the direction (arrow Y), the contact mechanism 13 moves in the direction of arrow Y Bend. At this time, the contact mechanism 13 tries to return to the original steady state by its elastic force.

  According to the above configuration, when the user applies an external force to widen the interval between the two vibration presenting units 12 and abuts the two vibration presenting units 12 around the scapula and the clavicle, the two vibration presenting units 12 receives an elastic force that causes the abutment mechanism 13 to return to the original steady state, and presses and presses around the scapula and around the clavicle from the front and back. As a result, an effect such as finger pressure from the front and back by the two vibration presenting units 12 is obtained around the shoulder blades and around the clavicle.

  Further, according to the above configuration, the user can easily wear the vibration device 100 with one hand so that the two vibration presenting portions 12 abut around the scapula and the clavicle. It is also possible to receive a hand-free massage while walking with the vibration device 100 mounted on the body.

  Here, as the configuration of the abutment mechanism 13, the configuration in which the two vibration presentation units 12 are suspended while being bent is shown, but the configuration in which the two vibration imparting bodies 11 are suspended while being bent is also possible. Good. Although the substantially U-shape is shown here as the shape of the suspension member, other shapes such as a substantially U-shape may be used. In short, it is only necessary that the two vibration presenting portions 12 sandwich the scapula and the clavicle and the contact mechanism 13 between them can bypass the shoulder.

  FIG. 2 is a diagram for explaining the installation position of the vibration imparting body 11 with respect to the vibration presenting unit 12. As shown in FIG. 2, the vibration presenting unit 12 includes a contact portion 12 a formed so as to contact the target site BD around the scapula and around the clavicle, and a non-contact portion formed so as not to contact the target site BD. The vibration imparting body 11 is installed on the non-contacting part 12 b of the vibration presenting part 12.

  As described above, the reason for providing the vibration imparting body 11 to the non-contact portion 12 b is to prevent the vibration imparting body 11 from directly applying vibration to a part of the target site BD. When the portion of the vibration presenting unit 12 on which the vibration imparting body 11 is installed is brought into direct contact with a part of the target site BD, the vibration is absorbed by the contact portion, and the entire target site BD is vibrated. It becomes difficult to spread. Therefore, as a configuration of the vibration presenting unit 12, a noncontact portion 12b not in direct contact with the target site BD is provided, and the vibration imparting body 11 is installed in the noncontact portion 12b. Thereby, the vibration imparted by the vibration imparting body 11 is made to spread over the entire target site BD via the vibration presenting unit 12.

  In addition, the vibration presentation part 12 should just have the contact part 12a which contacts object site | part BD, and the non-contact part 12b which does not contact object site BD directly, The shape is arbitrary. For example, the non-contact portion 12b may be expanded on the curved surface with respect to the contact portion 12a.

Second Embodiment
Next, a second embodiment of the present invention will be described based on the drawings. FIG. 3 is a diagram illustrating a configuration example of the vibration device according to the second embodiment. The vibration device 200 according to the second embodiment is for presenting vibration to a target site around the shoulder, around the shoulder blade or around the clavicle.

Although illustration is abbreviate | omitted, the vibration imparting body 21 is connected via the code | cord | chord CD with respect to the vibration source PL which supplies a vibration signal similarly to FIG.

  The vibration device 200 is provided with two sets of a vibration applying body 21 and a vibration presenting unit 22. The suspension part 23 is for hanging on the user's neck or head, and is constituted by an elastic suspension member that is suspended while bending between the two vibration presentation parts 22. In the example of FIG. 3, although the suspension part 23 is made into substantially U-shape, it is not limited to this shape.

  Here, in the steady state, the distance between the two vibration presenting units 22 and the degree of bending of the suspension 23 can, for example, allow the suspension 23 to be comfortably hung on the neck based on an adult having a standard body shape. It is preferable to design to the extent. Further, the distance between the two vibration presenting parts 22 and the degree of bending of the suspension part 23 is such that the suspension part 23 can be hung on the head without strain and the head can be held by the elastic force in the arrow Y direction. It is preferable to design to. Moreover, it is preferable to comprise the suspension part 23 so that the length can be expanded-contracted.

  When the two vibration presenting parts 22 come to the front of the body and the suspension part 23 is hung on the neck, the two vibration presenting parts 12 are located around the left and right clavicle. Also, when the two vibration presenting parts 22 come to the back of the body and hang the suspension 23 on the neck, the two vibration presenting parts 12 are located around the left and right shoulder blades. Moreover, when the suspension part 23 is hung on the head, the two vibration presenting parts 12 are positioned around the left and right shoulders. At this time, it is possible to adjust the position so that the two vibration presenting parts 12 properly contact around the shoulder, around the scapula, or around the clavicle by expanding and contracting the suspension 23.

  As shown in FIG. 3, the contact mechanism (not shown) in the second embodiment includes two vibration presenting portions for the target sites around the left and right shoulders, the left and right shoulder blades, and the left and right clavicles. 22, and is constituted by a rotation mechanism that enables the two vibration presenting portions 22 to be individually rotated. That is, the rotation mechanism sets the angles of the two vibration presenting units 22 by the rotation mechanism so that the two vibration presenting units 22 properly contact the target site around the left and right shoulders, around the left and right shoulder blades, or around the left and right clavicles. It can be adjusted.

  Here, in the state shown in FIG. 3A, as in the first embodiment, the two vibration presenting units 22 can be made to abut around the scapula and around the clavicle. Further, in the state shown in FIG. 3 (b), the two vibration presenting parts 22 can be made to abut around the left and right shoulder blades or around the left and right clavicles. Further, in the state shown in FIG. 3C, the two vibration presenting units 22 can be brought into contact with the left and right shoulders.

  The vibration presenting unit 22 in the second embodiment also has a contact portion and a non-contact portion as in the vibration presenting portion 12 shown in FIG. 2, and the vibration imparting body 21 is installed for the non-contact portion. The

  As described above in the first embodiment and the second embodiment, the vibration imparting bodies 11 and 21 are provided at any two locations around the shoulder, around the shoulder blade, and around the clavicle, so that the structure can be simplified. The sense of vibration can be spread throughout the body. Thereby, the user using the vibration device 100, 200 can feel comfortable that the whole body is encased in the sense of vibration.

Third Embodiment
Next, a third embodiment of the present invention will be described based on the drawings. FIG. 3 is a diagram illustrating a configuration example of a vibration device according to the third embodiment. The vibration device 300 according to the third embodiment is configured to output sound in addition to presenting vibration to a target region around the shoulder, around the scapula, or around the clavicle.

  Specifically, as shown in FIG. 4, the vibration device 300 according to the fourth embodiment includes a vibration applying body 31 for applying vibration to a target site, and a vibration presenting unit in which the vibration applying body 31 is installed. 32, an abutment mechanism 33 for causing the vibration presenting unit 32 to abut on the target site, and an earphone 34 (corresponding to a second vibration applying body) for outputting sound.

  The vibration applying body 31, the vibration presenting unit 32, and the contact mechanism 33 are configured in the same manner as the vibration applying body 11, the vibration presenting unit 12, and the contact mechanism 13 illustrated in FIG. Alternatively, the vibration applying body 31, the vibration presenting section 32, and the contact mechanism 33 are configured in the same manner as the vibration applying body 21, the vibration presenting section 22, and the suspension section 23 shown in FIG. It is good also as a structure which provides the rotation mechanism which is not illustrated as follows.

  In the third embodiment, the vibration imparting body 31 is connected to the sound reproducing apparatus AV that supplies the vibration signal and the sound signal via the first code CD1. Further, the earphone 34 is connected to the sound reproduction device AV via a first code CD1 and a second code CD2 extended therefrom.

  Thereby, a vibration signal for presenting vibration to the vibration applying body 31 is supplied from the sound reproducing device AV via the first code CD1, and a sound signal for outputting sound to the earphone 34. Is supplied from the sound reproducing device AV via the first code CD1 and the second code CD2.

  Here, the configuration in which the second code CD2 is extended from the first code CD1 and the earphone 34 is connected to the sound reproduction device AV via the first code CD1 and the second code CD2 is shown. However, it is not limited to this. For example, the first code CD1 and the second code CD2 are provided in a form that branches directly from the sound reproducing device AV, and the vibration imparting body 31 is connected to the sound reproducing device AV via the first code CD1, and the second The earphone 34 may be connected to the sound reproducing device AV via the code CD 2 of

  In the third embodiment, the vibration signal supplied to the vibration imparting body 31 is, for example, a signal generated so as to cause the user to image a predetermined sensation regarding tactile sensation. The predetermined sensation may be an audible feeling (slow, intense, rhythmical, etc.) felt when hearing a sound, or a tactile sensation (soft, hard, etc.) felt when touching an object. In this way, sound such as music can be reproduced by the audio signal supplied to the earphone 34 while giving a predetermined feeling to the user by the vibration signal supplied to the vibration applying body 31.

  Hereinafter, generation of the vibration signal supplied to the vibration imparting body 31 and the sound signal supplied to the earphone 34 will be described. The vibration signal generated here is a vibration signal that causes the user to image a predetermined sense of touch. In the present specification, such vibration signals are referred to as "tactile content". Further, the vibration signal and the audio signal are collectively referred to as “sound content”.

  FIG. 5 is a functional block diagram showing an example of the basic configuration of the haptic content generation device 500 according to the present embodiment. As shown in FIG. 5, the haptic content generation device 500 of the present embodiment includes a haptic content storage unit 50 as a storage medium. Further, the haptic content generation device 500 of the present embodiment includes, as its functional configuration, a haptic content extraction unit 51, a haptic content generation unit 52, a target information input unit 53, and a haptic parameter identification unit 54.

  The functional blocks 51 to 54 can be configured by any of hardware, DSP (Digital Signal Processor), and software. For example, when configured by software, each of the functional blocks 51 to 54 is actually configured by including a CPU, RAM, ROM, etc. of a computer, and a program stored in a recording medium such as RAM, ROM, hard disk, or semiconductor memory. Is realized by operating.

  The tactile content storage unit 50 stores tactile content having a unique tactile effect specified by n (n ≧ 2) tactile parameters, each representing one element of tactile sensation, into n tactile parameters. Are stored in association with each other. In this embodiment, an example of n = 2 is shown. Also, an example is shown in which a first haptic parameter relating to the strength of information and a second haptic parameter relating to the length of the divided section of information are used as two haptic parameters. Both the strength and the length of the divided section form an element of tactile sensation.

  That is, in the present embodiment, the haptic content storage unit 50 has a unique haptic effect specified by the first haptic parameter regarding the strength of the information and the second haptic parameter regarding the length of the divided section of the information. The haptic content is stored in association with the combination of the first haptic parameter and the second haptic parameter. The haptic parameter is a parameter that indicates the degree of opposing haptics (hereinafter referred to as "tactile pair") such as <hard-soft> and <coarse-smooth>.

  For example, it is possible to use the strength of the information as a haptic parameter for a <hard-soft> haptic pair. That is, the larger the value representing the strength, the harder it is, and the smaller the value representing the strength, the softer. In addition, the length of the divided section of information can be used as a tactile parameter relating to a tactile pair of <rough-smooth>. That is, the larger the value representing the length, the smoother, and the smaller the value representing the length, the rougher.

  FIG. 6 is a diagram schematically showing a storage example of haptic content stored in the haptic content storage unit 50. As shown in FIG. FIG. 6 shows a matrix-like tactile pair with the vertical axis representing “strength” as the first tactile parameter and the horizontal axis representing “division section length” as the second tactile parameter. Shows space. In the example of FIG. 6, <hard-soft> is used as the tactile pair represented by the first tactile parameter (strength), and the tactile represented by the second tactile parameter (length of the divided section). A pair using <coarse-smooth> is shown.

  In the example of FIG. 6, 25 matrix spaces are formed by dividing the maximum to minimum intensity levels into 5 levels and dividing the maximum to minimum length of the divided sections into 5 levels. Yes. The 25 matrix spaces are assigned index numbers 1 to 25 respectively. The haptic content storage unit 50 stores haptic content according to the combination of the strength and the length of the divided section in each of the 25 matrix spaces.

  The haptic content stored here is information that enables a person to obtain a tactile sensation. In the present embodiment, vibration information is used as tactile content. When storing vibration information as tactile content, for example, at the position of index number “1”, vibration information with the maximum strength and the minimum length of the divided section, that is, the image of the hardest and roughest can be transmitted. Vibration information is stored. For example, at the position of the index number “25”, vibration information having the minimum intensity and the maximum length of the divided section, that is, vibration information that can transmit the image that is the softest but the smoothest is stored.

  Note that what is used as two pairs of tactile qualities for specifying tactile content can be arbitrarily determined according to the use of the tactile content generated by the haptic content generation apparatus 500 of the present embodiment. . That is, although <hard-soft> and <coarse-smooth> are used here as two pairs of touch materials, it is not limited thereto. For example, <large-small>, <sharp-dull>, <heavy-light>, <rough-smooth>, etc. may be used as another example of the tactile pair.

  5 shows a configuration in which the tactile content generation device 500 includes the tactile content storage unit 50. However, the tactile content storage unit 50 is provided outside the tactile content generation device 500, and the tactile content generation device 500 is external. The haptic content may be acquired from the haptic content storage unit 50 and used.

  For example, the haptic content storage unit 50 external to the haptic content generation device 500 is configured of a removable storage medium removable from the haptic content generation device 500. Alternatively, the haptic content storage unit 50 external to the haptic content generation device 500 is configured of an external device (for example, an external storage, a server, etc.) connected to the haptic content generation device 500 via a communication network.

  The target information input unit 53 inputs target information in which values corresponding to the intensities are continuously or intermittently connected. As an example of the target information, time-series waveform information is input in the present embodiment. The waveform information input here may be an analog signal or digital data. The waveform information to be input may be any information whose amplitude changes with the passage of time, and the type is arbitrary.

  For example, audio signals, video signals, measurement signals of various measuring instruments such as seismometers, anemometers, and actinometers, waveform measurement data by an oscilloscope, stock price fluctuation data, and the like can be mentioned, but these are merely examples. When an audio signal is input, it is preferable that it be an audio signal different from the audio signal (audio signal supplied to the earphone 34) constituting the audio content. When the same audio signal as the audio signal constituting the acoustic content is input as target information and a tactile content is generated from this, the sound is also output by the tactile content given to the vibration imparting body 31, and the audio supplied to the earphone 34 It is because it appears as noise to the voice output based on the signal.

  Therefore, even if the waveform information input as the target information by the target information input unit 53 is supplied to the vibration imparting body 31 with an increased volume (with an increased amplitude), a waveform with a wavelength that is difficult for the human ear to hear. Information is preferred. Specifically, it is preferable to use waveform information that produces a vibration signal of 30 to 80 Hz, preferably 35 to 50 Hz.

  The haptic parameter identification unit 54 divides the waveform information input by the target information input unit 53 into a plurality of segments in the time axis direction, identifies the amplitude as the first haptic parameter from each divided section, and The time length of the divided section is specified as the tactile parameter. At this time, as pre-processing, the waveform information is subjected to low-pass fill processing to extract an envelope of the input waveform information, and the first tactile parameter (amplitude) and a plurality of divided sections are targeted for the envelope. The second haptic parameter (the length of time of the divided section) may be specified.

  FIG. 7 is a diagram for explaining an example of processing contents by the haptic parameter identifying unit 54. As shown in FIG. FIG. 7 shows the waveform information input by the target information input unit 53 (or envelope waveform information subjected to low-pass filter processing as preprocessing by the haptic parameter specification unit 54).

  First, the haptic parameter specifying unit 54 divides the waveform information illustrated in FIG. 7 into a plurality of pieces in the time axis direction. In FIG. 7, as one example, it is divided at each time when the amplitude of the waveform becomes minimum. That is, from the start point of the waveform to the first minimum value is the first divided section T1, and from the first minimum value to the second minimum value is the second divided section T2, the second minimum value The waveform information is divided into a plurality of parts in the time axis direction, as in the third divided section T3,...

  The way of dividing the waveform information is not limited to the example shown in FIG. For example, the waveform information may be divided into a plurality of sections at each time when the amplitude of the waveform reaches a maximum. Alternatively, in the case of waveform information having a positive value amplitude and a negative value amplitude, the waveform information may be divided into a plurality of sections every time the amplitude value becomes zero.

  The tactile parameter specifying unit 54 specifies the representative amplitudes h1, h2, h3,... As the first tactile parameters from the respective divided sections T1, T2, T3,. The length t1, t2, t3,... Of time of the divided section is specified as the quality parameter. Here, the representative amplitudes h1, h2, h3,... Are divided with the larger one of the minimum value of the start point or the minimum value of the end point in each of the divided sections T1, T2, T3,. It shows the value of the difference from the maximum value in the sections T1, T2, T3,.

  That is, since there is only one minimum value for the divided section T1, the difference between this minimum value and the maximum value becomes the representative amplitude h1. In the divided section T2, since the minimum value at the start point of the section is larger than the minimum value at the end point, the difference between the minimum value at the start point and the maximum value is the representative amplitude h2. In the divided section T3, since the minimum value of the end point is larger than the minimum value of the start point of the section, the difference between the minimum value and the maximum value of the end point becomes the representative amplitude h3.

  In addition, the identification method of the representative amplitude shown here is an example, It is not limited to this. For example, the minimum value of the minimum value of the start point or the minimum value of the end point in each divided section T1, T2, T3,... And the maximum value in the divided sections T1, T2, T3,. May be specified as the representative amplitude.

  When waveform information having positive amplitude and negative amplitude is divided at every time when the amplitude value becomes zero, positive maximum value or negative minimum value in each divided section is set as the first value. It may be specified as the representative amplitude of the tactile parameter. Here, regarding the negative minimum value, the absolute value may be specified as the representative amplitude of the first tactile parameter.

  The haptic content extraction unit 51 is a combination of the first tactile parameter (amplitude) and the second tactile parameter (length of time of divided section) specified from each divided section by the tactile parameter specification section 54. Are sequentially specified, and a plurality of tactile contents corresponding to the specified combination of the plurality of sets are sequentially extracted from the tactile content storage unit 50.

  That is, the tactile content extraction unit 51 combines the combinations {h1, t1}, {h2, t2}, {h3 of the representative amplitudes and the lengths of the divided sections identified from the divided sections T1, T2, T3,. , T3},. Then, the tactile content corresponding to each of the designated combinations is extracted in order on the tactile content matrix space shown in FIG.

  The haptic content generation unit 52 determines whether or not a plurality of haptic content extracted in order by the haptic content extraction unit 51 has a repetition of a pattern consisting of a combination of two or more different haptic content, and repeatedly To extract haptic content groups making up as tactile content. The haptic content group constituting the repetition is information capable of transmitting a meaningful message to the receiver, and in the present embodiment, this is generated as haptic content. The reason will be described below.

  First of all, when giving a certain message to a person by touch, it is important to make a difference in touch. For example, a person will not feel pressure if it keeps receiving the same pressure all the time, but if it makes a difference in pressure, it will feel pressure more strongly. And, from the series of differences, it becomes possible to express a certain kind of message. For example, in the matrix space shown in FIG. 6, when the tactile content with index number 20 and the tactile content with index number 25 are extracted in order, the strength changes slowly over a long time with a relatively weak strength. A difference arises, which makes it possible to express the message of "soft and smooth" feeling.

  Second, by repeating the tactile difference as described above twice or more, it is possible to give a person the impression that it is something special (not accidental). That is, not only the tactile content of No. 20 and the tactile content of No. 25 are extracted once in order, but also by repeating twice or more like No. 20 → No. 25 → No. 20 → No. 25. It is possible to convey the message more strongly. Here, although an example in which two haptic content is repeated is shown, one in which three or more haptic content are repeated is also a haptic content.

  Note that the haptic content generated by the haptic content generation unit 52 is stored in, for example, a storage medium included in the haptic content generation apparatus 500 or a removable storage medium that is detachable from the haptic content generation apparatus 500. Alternatively, haptic content may be transmitted to an external device (for example, an external storage, a server, etc.) connected to the haptic content generation device 500 via a communication network and stored. In the present embodiment, the haptic content thus stored is used as an element of the acoustic content.

  Below, an example of the determination algorithm of the repeating pattern by the haptic content production | generation part 52 is demonstrated. FIG. 8 is a diagram for explaining an algorithm for determining a repetitive pattern by the haptic content generation unit 52. FIG. 8A shows a permutation of index numbers of ten tactile contents extracted in order by the tactile content extracting unit 51.

  The haptic content generation unit 52 first extracts, as a pattern, an index number immediately before the appearance of the same index number as the key, using the leading index number extracted by the haptic content extraction unit 51 as a key. Here, the pattern refers to a combination of two or more different index numbers (tactile content indicated thereby).

  For example, when the same index number as key is continuous (for example, in the case of "11"), the pattern up to immediately before the appearance of the same index number as key is used as a pattern without giving the restriction of "two or more different". When extracted, only the first first index number "1" is extracted as a pattern. In the present embodiment, a pattern consisting of only one such index number is not extracted. When this is extracted as a pattern, “11” becomes tactile content in which “1” is repeated twice, but this is not suitable as tactile content because there is no difference in the sequence of tactile content. is there.

  After extracting one pattern, the tactile content generation unit 52 next extracts a new pattern as a pattern immediately before the same index number as the key appears, with the next index number of the extracted pattern as the key. The haptic content generation unit 52 performs the above-described processing until the end of the index numbers sequentially extracted by the haptic content extraction unit 51.

  If the same index number as the key is not found even after searching up to the last index number with the first index number as the key, the second index number from the beginning is reset to the key, and the key Up to just before the same index number appears as a pattern is extracted. This process is repeated while changing the key until a pattern is found. FIG. 8B shows the result of performing such pattern extraction processing.

  In the example of FIG. 8, first, the index number “1” at the top is used as a key, and up to immediately before the appearance of the index number identical to the key is extracted as a pattern. Thus, “123” is extracted as the first pattern. Next, with the next index number (fourth index number) “1” of the extracted first pattern as a key, up to immediately before the appearance of the same index number as the key is extracted as a pattern. Thereby, “123” is extracted as the second pattern.

  Next, with the next index number (the seventh index number) “1” of the extracted second pattern as a key, up to immediately before the appearance of the same index number as the key is extracted as a pattern. Thereby, “14” is extracted as the third pattern. Furthermore, the index number (9th index number) “1” next to the extracted third pattern was used as a key, and it was tried to extract as a pattern until just before the same index number as the key appeared The number is not found, and the remaining "13" is extracted as the fourth pattern.

  In the example of FIG. 8, the pattern of "123" is repeated twice. Therefore, the haptic content generation unit 52 extracts the haptic content group “123123” constituting this repetition, and generates this as haptic content.

  In the example of FIG. 8, as shown in FIG. 8C, when the second index number “2” is set as a key, it is possible to extract the repetition of the pattern “231”. Therefore, the haptic content generation unit 52 extracts a plurality of haptic content groups “123123” and “231231” constituting repetition by performing pattern extraction processing while changing the setting position of the key from the top in order, These may be generated as tactile content. Alternatively, all the index numbers may be sequentially set as the key, and the determination process of the repetitive pattern may be performed.

  In addition, although the determination example of the repeating pattern in the case where the number of haptic content extracted by the haptic content extraction part 51 is ten was demonstrated here, there may be many haptic content. Therefore, the haptic content generation unit 52 divides a plurality of tactile contents extracted in order by the tactile content extraction unit 51 into a predetermined number from the top and groups them, and repeats pattern determination processing for each group. Also good.

  By transmitting the tactile content generated as described above to the user through the vibration device 300 as one element of the acoustic content, a series of differences in repeated tactile content is given to give a meaningful tactile effect. The tactile message nature (narrative) can be clearly transmitted to the user.

  In the above embodiment, from the plurality of haptic content extracted from the haptic content storage unit 50, a tactile content group consisting of one type of repetitive pattern is extracted, and the extracted tactile content group is used as it is as tactile content. However, the present invention is not limited to this. For example, a tactile content group composed of a plurality of types of repetitive patterns may be extracted and combined to generate tactile content.

  In the above-described embodiment, an example has been described in which one index number is set to Key, and the pattern is extracted until just before the same index number as that Key appears. However, the present invention is not limited to this. For example, a combination of a plurality of index numbers may be set as Key, and the pattern up to immediately before the combination of the same index number as that Key may be extracted as a pattern.

  In the above embodiment, for example, as shown in FIG. 8B, when the repetition of the pattern “123 | 123” is detected, the tactile content group “123123” constituting the repetition is used as the tactile content. Although the example to produce | generate was demonstrated, this invention is not limited to this. For example, a combination of “123” in an arbitrary number may be generated as tactile content.

  In addition, it is possible to generate one ("231" or "312") in which the order of "123" is replaced cyclically, and to generate a combination of these as haptic content. Here, the tactile content may be generated by combining the same pattern such as “231231” or “3121212”, or the tactile content may be generated by arbitrarily combining different patterns such as “12323112”. It may be.

  Moreover, although the said embodiment demonstrated the example which handles the waveform information of the form in which the value corresponding to an intensity | strength is continuously or intermittently connected as object information input by the object information input part 53, it is originally like that. It is also possible to input information obtained by converting information which is not in the form described above into the form.

  For example, in the case of an audio signal, if it has a certain length of time, it can be said that values corresponding to the intensity are continuously or intermittently connected. On the other hand, in the case of a sound that ends in an instant, there is an amplitude, but it does not have a length that can be divided into a plurality along the time axis. However, when the instantaneous sound is frequency-analyzed and converted to a frequency-axis signal, information with different amplitudes for each frequency, that is, information corresponding to the intensity along the frequency axis, becomes information. This is information that can be input at the input unit 53. In addition, frequency spectrum information, histogram information, image information, moving image information, text information, motion information representing the motion of an object, and the like can be input from the target information input unit 53 as target information.

  In the above embodiment, as shown in FIG. 6, an example in which the length of the division section is taken on the horizontal axis has been described, but the reciprocal of the length may be taken.

  In the above-described embodiment, n = 2 and the first tactile parameter related to the information strength and the second tactile parameter related to the length of the divided section of information are specified as the two tactile parameters. Although an example has been described, n may be 3 or more. Note that when n ≧ 3, tactile content corresponding to a combination of n tactile parameters is stored as an n-dimensional hierarchical space of three or more layers instead of a two-dimensional matrix space as shown in FIG. Will do.

  In the above-described embodiment, an example has been described in which both the first tactile parameter related to the strength of information and the second tactile parameter related to the length of the divided section of information are specified. Also good.

  That is, the tactile parameter specifying unit 54 divides the target information input by the target information input unit 53 into a plurality of pieces, and from each divided section, relates to the first tactile parameter related to the strength of information and the length of the divided section. It is possible to specify n (n ≧ 2) tactile parameters using at least one of the second tactile parameters.

  For example, in the case of n = 3, it is possible to specify one or two first tactile parameter and two or one second tactile parameter. Alternatively, three different ones of the first haptic parameters may be specified, or three different ones of the second haptic parameters may be specified.

  When n touch quality parameters are specified only with the first touch quality parameter related to the strength of information, for example, n types of target information are input by the target information input unit 53. Then, the tactile parameter specifying unit 54 divides the input n types of target information into a plurality of pieces, and specifies one first tactile parameter from each divided section of the n types of target information. Thus, a plurality of combinations of the n first tactile parameters are specified.

As an example, it is assumed that the target information input unit 53 inputs the following digital values as three types of information of heart rate, acceleration (body movement), and blood flow rate as information of the touch object conversion target.
Heart rate: 79, 60, 79, 75, 74, 79, 75
Acceleration: 40, 10, 30, 40, 35, 40, 20
Blood flow rate: 80, 60, 40, 60, 80, 60, 80

In this case, the haptic parameter specifying unit 54 divides each of the three types of input target information for each input value, and specifies the first haptic parameter from each divided section of the three types of target information. Thus, the combination of the three first tactile parameters is specified as follows.
{79, 40, 80}, {60, 10, 60}, {79, 30, 40}, ...

  Also, when n tactile parameters are specified only by the second tactile parameter related to the length of the divided section of information, for example, n types of target information are input by the target information input unit 53. Then, the tactile parameter specifying unit 54 divides the input n types of target information into a plurality of pieces, and specifies the second tactile parameters one by one from each divided section of the n types of target information. Generates a plurality of combinations of n second haptic parameters.

  As an example, it is assumed that the target information input unit 53 inputs digital values similar to those described above with respect to three types of information of heartbeat, acceleration, and blood flow. In this case, for example, the haptic parameter identifying unit 54 divides three types of target information in units of until the same value is input, and the second haptic from the divided sections of the three types of target information. By specifying the parameters, a plurality of combinations of three second haptic parameters are specified.

  In the case of the above example, regarding the heart rate, the same value as the first “79” appears two times later, and then the same value appears three more times later. 3 As for the acceleration, the same value as the first "40" appears next after three, and the second same value appears after another two, so the length of the divided section is 3, 2. As for the blood flow volume, the same value as the first "80" appears next after 4 and the second same value appears after 2 more, so the length of the divided section is 4, 2. In this case, the tactile parameter specifying unit 54 specifies the combination of the second tactile parameters as {2, 3, 4}, {3, 2, 2}.

  Although an example of inputting a digital value as information on a plurality of types of haptic conversion targets has been described here, it goes without saying that an analog signal may be input. In this case, the method described in the above embodiment can be applied to the method for specifying the tactile parameter relating to the strength and the tactile parameter relating to the length of the divided section.

  In addition, here, an example has been described in which only one of the tactile parameters related to strength or the tactile parameters related to the length of the divided sections is specified from input information of a plurality of types of tactile conversion targets. You may make it identify from object information. For example, as in the above-described embodiment, one type of target information may be divided into a plurality of sections, and a plurality of tactile parameters related to strength may be specified from each divided section (for example, the maximum intensity value and For example, the minimum value is a tactile parameter. Further, when one type of target information is divided into a plurality of sections, the information may be divided into a plurality of sections according to different methods, and the length of the divided section divided by each method may be used as a tactile parameter.

  In addition, here, an example has been described in which only tactile parameters related to strength or only tactile parameters related to the length of a divided section are specified from input information of a plurality of types of tactile conversion targets, but the present invention is not limited thereto. Not. For example, both the tactile parameter related to the strength and the tactile parameter related to the length of the divided section may be combined and specified from the input information of a plurality of types of haptic conversion target.

  Next, an audio content generation device will be described. FIG. 9 is a functional block diagram showing an example of a functional configuration of the audio content generation apparatus 600 according to the present embodiment. As shown in FIG. 9, the acoustic content generation device 600 of this embodiment includes a tactile content acquisition unit 61, an audio signal acquisition unit 62, a vibration waveform processing unit 63, and an acoustic content generation unit 64 as its functional configuration. . In addition, a tactile content storage unit 601 and an audio signal storage unit 602 are connected to the acoustic content generation apparatus 600 of the present embodiment.

  Each of the functional blocks 61 to 64 can be configured by any of hardware, DSP, and software. For example, when configured by software, each of the functional blocks 61 to 64 is actually configured by including a CPU, RAM, ROM, and the like of a computer, and is stored in a recording medium such as a RAM, ROM, hard disk, or semiconductor memory. Is realized by operating.

  The haptic content storage unit 601 stores the haptic content generated by the haptic content generation apparatus 500 configured as shown in FIG. In the present embodiment, the tactile content storage unit 601 generates tactile content as vibration information by the tactile content generation device 500 when vibration information is used as tactile content stored in the tactile content storage unit 50 of FIG. Remember. The haptic content stored in the haptic content storage unit 601 is time-series waveform information composed of a haptic content group having a repetition of a pattern composed of a combination of two or more different haptic contents (vibration information).

  Note that the haptic content storage unit 601 may be a storage medium included in the haptic content generation device 500 illustrated in FIG. 5, or may be a personal computer, a smartphone, a tablet terminal, or the like outside the haptic content generation device 500. It may be an information processing device or a removable storage medium. In addition, the haptic content storage unit 601 may be an external device (for example, an external storage, a server, etc.) connected to the acoustic content generation device 600 via a communication network.

  The audio signal storage unit 602 stores waveform information of an arbitrary audio signal. For example, the audio signal storage unit 602 stores waveform information of an audio signal representing a music piece of any music. The waveform information of the audio signal stored in the audio signal storage unit 602 may be an analog signal or digital data. Note that the audio signal storage unit 602 can be configured as an information processing device such as a personal computer, a smartphone, or a tablet terminal outside the acoustic content generation device 600, or a removable storage medium. Further, the audio signal storage unit 602 may be an external device (for example, an external storage, a server, etc.) connected to the audio content generation device 600 via a communication network.

  The haptic content acquisition unit 61 acquires the haptic content stored in the haptic content storage unit 601, that is, as described above, the haptic content generated from the haptic content that is vibration information by the haptic content generation device 500 of FIG. 5. To do. The audio signal acquisition unit 62 acquires the audio signal stored in the audio signal storage unit 602.

  The vibration waveform processing unit 63 processes the waveform information of the haptic content acquired by the haptic content acquisition unit 61 based on the waveform information of the audio signal acquired by the audio signal acquisition unit 62. The total time length of waveform information of haptic content acquired by the haptic content acquisition unit 61 may not be the same as the total time length of waveform information of audio signal acquired by the audio signal acquisition unit 62. In this case, the vibration waveform processing unit 63 pre-processes the waveform information of the tactile content so that the total time length thereof is the same as the total time length of the waveform information of the audio signal, and then performs the main processing described later. .

  In addition, pre-processing may be, for example, processing of connecting waveform information of haptic content acquired by the haptic content acquisition unit 61 repeatedly and cutting it at the same time as the total time length of waveform information of the audio signal. Is possible. Alternatively, the pre-processing may be a process of extending the pitch of the waveform information of the haptic content acquired by the haptic content acquisition unit 61. However, since the message property of the tactile content may change if the pitch of the waveform information of the tactile content is changed, it is preferable to use the former method.

  The total time length of the waveform information of the haptic content acquired by the haptic content acquisition unit 61 and the total time length of the waveform information of the audio signal acquired by the audio signal acquisition unit 62 are not necessarily matched. For example, the acoustic content may be generated by combining the waveform information of tactile content only for a specific section in the entire time length of the waveform information of the audio signal. In this case, the vibration waveform processing unit 63 performs the pre-processing so as to synchronize the waveform information of the tactile content with a specific section in the entire time length of the waveform information of the audio signal, and then performs the main processing described later. .

  The acoustic content generation unit 64 generates acoustic content by a combination of the audio signal acquired by the audio signal acquisition unit 62 and the tactile content processed by the vibration waveform processing unit 63. For example, the acoustic content generation unit 64 uses the tactile content processed by the vibration waveform processing unit 63 as the first channel information (vibration signal supplied to the vibration applying body 31), and uses the audio signal acquired by the audio signal acquisition unit 62. Sound content to be second channel information (audio signal supplied to the earphone 34) is generated.

  Details of the acoustic content will be described later, and the details of the main processing performed by the vibration waveform processing unit 63 will be described below. FIG. 10 is a block diagram showing a functional configuration example of the vibration waveform processing unit 63, and shows a functional configuration example for the vibration waveform processing unit 63 to perform main processing on waveform information of haptic content. As shown in FIG. 10, the vibration waveform processing unit 63 includes a feature extraction unit 63A, a weight information generation unit 63B, and a weight processing unit 63C as its functional configuration.

  The feature extraction unit 63A extracts a plurality of feature locations that can be distinguished from other locations in the waveform information of the audio signal acquired by the audio signal acquisition unit 62. For example, in the waveform information of the audio signal acquired by the audio signal acquisition unit 62, the feature extraction unit 63A extracts a portion where the amplitude value increases by a predetermined value or more during a predetermined time as a characteristic portion.

  The weight information generation unit 63B generates weight information whose value changes with time in the time section of the adjacent feature location based on the plurality of feature locations extracted by the feature extraction unit 63A. For example, the weight information generation unit 63B determines the value over time from the time when one feature location is extracted to the time when the next feature location is extracted based on the plurality of feature locations extracted by the feature extraction unit 63A. Weight information that gradually decreases is generated.

  FIG. 11 is a diagram for explaining the processing contents of the feature extraction unit 63A and the weight information generation unit 63B. Here, FIG. 11A shows waveform information of the audio signal acquired by the audio signal acquisition unit 62. FIG. 11B shows a state in which the weight information generated by the weight information generation unit 63B is schematically overlapped with the waveform information of the haptic content acquired by the haptic content acquisition unit 61. Here, there is shown waveform information after pre-processing the waveform information of the haptic content so that the total time length is the same as the total time length of the waveform information of the audio signal.

In the waveform information of the audio signal shown in FIG. 11A, the feature extraction unit 63A includes a plurality of feature points F ₁ ,... Where the amplitude value increases by a predetermined value or more during a predetermined time (for example, 0.1 seconds). Extract as F ₂ , F ₃ ,. That is, the feature extraction unit 63A extracts places where the amplitude value of the waveform information of the audio signal increases sharply as feature places F ₁ , F ₂ , F ₃ ,.

The weight information generation unit 63B selects one feature location F _i (i = 1, 2,...) Based on the plurality of feature locations F ₁ , F ₂ , F ₃ ,... Extracted by the feature extraction unit 63A. The weight information is generated such that the value gradually decreases with time from the time when ・) is extracted until the time when the next feature location F _{i + 1} is extracted. The weight information is information in which the weight value (all positive values) takes from the minimum value to the maximum value, and is schematically shown as a sawtooth wave in FIG.

In the example of FIG. 11B, the weight value becomes maximum at the time when one feature point F _i is extracted, and the value gradually decreases with time in a linear or stepwise manner. Weight information is generated such that the weight value is again maximized at the time when _{i + 1} is extracted. Here, the weight information generation unit 63B has the maximum weight value at the time when one feature location F _i is extracted, and the weight value is set to the minimum value at the time when the next feature location F _{i + 1} is extracted. The following weight information is generated.

In addition, the production | generation process of the weight information shown here is an example, It is not limited to this. For example, FIG. 11B shows an example in which the weight value gradually decreases linearly at a constant rate, but the next feature location F _{i + 1} is extracted from the time when one feature location F _i is extracted. Until the time, weight information may be generated such that the value gradually decreases in accordance with a predetermined quadratic function or logarithmic function.

In addition, the rate at which the weight value gradually decreases (the inclination angle of the hatched portion indicated by the sawtooth wave) may be the same for all sections. In this case, if between one feature point F _i and the next feature point F _{i + 1} is a long interval, the weight value reaches a minimum value before reaching the next feature point F _{i + 1.} In this case, for example, after the weight value reaches the minimum value, the weight information generation unit 63B generates weight information that fixes the weight value to the minimum value until the next feature location F _{i + 1} .

Further, the maximum value and the minimum value of the weight values may not be fixed, and may be variable values that change according to a predetermined condition. For example, the maximum value of the weight value may be made variable according to the magnitude of the amplitude value at the characteristic portion. In this case, the weight information generation unit 63B sets weight information so that the weight value increases as the amplitude value at one feature location F _i increases, and the value gradually decreases from that to the next feature location F _{i + 1.} Generate In this way, a larger weight value is set as the amplitude value of the feature place F _i is larger among the plurality of feature places F _i where the amplitude value increases by a predetermined value or more during the predetermined time.

  The weight processing unit 63C obtains waveform information of the haptic content acquired by the haptic content acquisition unit 61 (including the haptic content that has been pre-processed by the vibration waveform processing unit 63; the same applies hereinafter) as the weight information generation unit 63B. It processes by the weight information produced | generated by. For example, the weight processing unit 63C processes the waveform information of the haptic content by multiplying the amplitude value of the waveform information of the haptic content by the weight value of the weight information.

  That is, the weight processing unit 63C is similar to the amplitude value at each time of the waveform information of the haptic content shown in FIG. 11B, at each time schematically shown as a sawtooth wave in FIG. Multiply the weight value. In FIG. 11B, the waveform information of the tactile content and the weight information are shown in an overlapping manner to clearly show the correspondence between the amplitude value of the waveform information at each time and the weight value to be multiplied by this. Because.

  In the case where the acoustic content is generated by combining the waveform information of the tactile content only with respect to the waveform information of the audio signal in the specific section, out of the total time length of the waveform information of the audio signal, the feature extraction unit 63A, the weight information generation unit The 63B and the weight processing unit 63C may execute each process only in the specific section. That is, the feature extraction unit 63A may extract the feature region of the audio signal only in the specific section. Further, the weight information generation unit 63B may generate weight information only in a specific section. Further, the weight processing unit 63C may multiply the amplitude value of the waveform information of the haptic content synchronized with the waveform information of the audio signal of the specific section only in the specific section by the weight value.

  As described above, the acoustic content generation unit 64 uses the tactile content processed by the vibration waveform processing unit 63 as described above as the first channel information, and uses the audio signal acquired by the audio signal acquisition unit 62 as the second channel. A sound content is generated by a combination of information. FIG. 12 is a diagram showing acoustic content generated by the acoustic content generation unit 64. As shown in FIG. 12A shows the waveform information (second channel information) of the audio signal acquired by the audio signal acquisition unit 62, and FIG. 12B shows the waveform of the tactile content processed by the dynamic waveform processing unit 23. Information (first channel information) is shown. The waveform information of the audio signal shown in FIG. 12A is the same as the waveform information of the audio signal shown in FIG.

  When the audio signal acquired by the audio signal acquisition unit 62 is a monaural audio signal, as described above, the waveform information of the audio signal (weight for processing the waveform information of the audio content) illustrated in FIG. The waveform information of the audio signal which is the extraction target of the characteristic portion to generate the information, and the waveform information of the audio signal shown in FIG. 12A (the waveform information of the audio signal constituting the second channel information of the acoustic content) Is the same.

  On the other hand, when the audio signal acquired by the audio signal acquisition unit 62 is a stereo audio signal, the waveform information of the audio signal shown in FIG. 11A and the waveform information of the audio signal shown in FIG. May be the same, but not necessarily the same. For example, an audio signal to be a feature extraction target may be an audio signal of the left channel, and an audio signal forming second channel information of audio content may be an audio signal of the right channel. Of course, the reverse is also possible.

  In the former case, the feature extraction unit 63A extracts a plurality of feature locations from the waveform information of the audio signal of the left channel, the weight information generation unit 63B generates weight information based on the feature locations, and the weight processing unit 63C The waveform information (first channel information) of the haptic content is generated by processing the waveform information of the haptic content using the weight information. The acoustic content generation unit 64 generates the acoustic content by combining the tactile content processed by the vibration waveform processing unit 63 as described above and the right channel audio signal acquired by the audio signal acquisition unit 62. .

  The acoustic content generated as described above is composed of a combination of tactile content constituted by repeating a pattern consisting of a combination of two or more different tactile content (vibration information) and an arbitrary audio signal. Is. Moreover, the haptic content to be combined with the audio signal is haptic content in which the amplitude value of the waveform is processed by the weight information whose weight value changes in a manner synchronized with the characteristic portion of the audio signal. For this reason, by transmitting the acoustic content to the person through the vibration device 300, the sound reproduced based on the sound signal is provided, and at the same time, the tactile message property (by the vibration of the tactile content synchronized with the feature of the sound ( Narrative) can be clearly communicated.

  In addition, the several feature location which feature extraction part 63A extracts from the waveform information of an audio | voice signal is not limited to the example shown to the said embodiment. For example, the feature extraction unit 63A may extract, as a feature location, a location where the amplitude value is a predetermined value or more in the waveform information of the audio signal acquired by the audio signal acquisition unit 62. Alternatively, the waveform information of the audio signal may be subjected to frequency analysis for each time, and a location where the included frequency component changes abruptly may be extracted as a feature location. Alternatively, the analysis similar to that shown in FIG. 7 may be performed on the waveform information of the audio signal, and a location where the value of h / t changes abruptly may be extracted as a feature location.

In the above-described embodiment, the weight information generation unit 63B generates weight information that gradually decreases from the time when one feature location F _i is extracted to the time when the next feature location F _{i + 1} is extracted. However, the present invention is not limited to this. For example, the feature extraction section 63A is to be extracted as a feature point suddenly decreases places the amplitude value during a predetermined time in the waveform information of the audio signal, weight information generation unit 63B is, in the one feature point F _i Weight information may be generated such that the value gradually increases from the extracted time to the time when the next feature part F _{i + 1} is extracted.

  The vibration device 300 according to the third embodiment configured as described above can be used not only for a user to receive a massage, but also as a “device for walking while listening to a touch”. It is.

  In the third embodiment, the first tactile parameter and the second tactile parameter identified from the target information are analyzed by analyzing the target information input by the target information input unit 53 of FIG. 5. Although an example has been described in which the combination of the first haptic parameter and the second haptic parameter is sequentially designated by inputting the haptic content extraction unit 51, the present invention is not limited to this.

  For example, a user who wants to generate desired haptic content may manually specify the first tactile parameter and the second tactile parameter. In this case, the target information input unit 53 and the tactile parameter specifying unit 54 shown in FIG. 5 are unnecessary. As an example, the tactile content extraction unit 51 displays the matrix illustrated in FIG. 6 on a computer screen, and allows the user to sequentially specify a desired position using an operation device such as a touch panel or a mouse. The combination of the tactile parameter and the second tactile parameter is specified in the order of a plurality of sets. In response to this, the tactile content extraction unit 51 sequentially extracts tactile content corresponding to the positions sequentially specified on the matrix from the tactile content storage unit 50.

  Alternatively, the tactile content extracting unit 51 may sequentially specify a combination of the first tactile parameter and the second tactile parameter in a random manner or in accordance with a predetermined rule.

  In the third embodiment, an example is described in which the acoustic content is generated with the haptic content as the first channel information and the audio signal as the second channel information, but the present invention is not limited to this. For example, in addition to the above two channel information, the audio content may be generated by including a third or more number of channel information.

  As an example, acoustic content may be generated in which the haptic content is the first channel information, the left channel audio signal is the second channel information, and the right channel audio signal is the third channel information. Moreover, you may make it produce | generate the acoustic content which uses 1st channel information for tactile content, 2nd channel information for an audio signal, and 3rd channel information for a video signal. Here, the output of the video may be performed, for example, on a display provided in the sound reproducing apparatus AV.

  Further, instead of the earphone 34, the same configuration as that of the vibration applying body 31 and the vibration presenting section 32 is provided, and this is used as the second vibration applying body and the second vibration presenting section. To provide the first haptic content, which is a first vibration signal generated to cause the user to image a predetermined sensation regarding the image, to the user, The second haptic content may be supplied, which is a second vibration signal generated to cause the second haptic signal. Here, the first haptic content and the second haptic content may be the same or different.

  Moreover, although the said 3rd Embodiment demonstrated the example using what processed the waveform information of the tactile content according to weight information as a vibration signal supplied with respect to the vibration provision body 31, this invention is not limited to this .
