Description

  The present invention relates to a communication device for human body communication that performs communication using a human body as a signal transmission path.

  Conventionally, as a communication device for human body communication, those described in Patent Documents 1 and 2 below are known. These communication devices described in Patent Documents 1 and 2 have a pair of reference electrodes and signal electrodes, and in the case of the communication device described in Patent Document 1, each electrode is disposed so as to contact the human body. Further, in the case of the communication device described in Patent Document 2, the signal electrode is arranged so that electrostatic coupling is stronger with respect to the human body than the reference electrode.

  If a communication device having such a structure is used, a potential difference is generated between the reference electrode and the signal electrode, thereby transmitting a signal to another communication device or detecting a potential difference generated between the reference electrode and the signal electrode. It was possible to receive signals from other communication devices.

  Further, regarding a specific form of such a communication device, the following Patent Document 1 also discloses a glasses-type communication device that can be worn on the human head (see Patent Document 1: FIG. 7C). . In this spectacle-type communication device, the reference electrode and the signal electrode are incorporated inside the temples on the left and right sides of the spectacles, and extend in the front-rear direction inside each temple.

  However, when a user wears the above-described glasses-type communication device, there is a difference in the amount of hair that is sandwiched between the skin and the temple in the temporal region, so that a person with a large amount of hair or a person with long hair As a result, the electrodes are more likely to be separated from the skin, which may cause a decrease in communication performance. In addition, there is a risk that communication performance may vary between a person with a large amount of hair and a person with a small amount of hair, or a person with long hair and a person with short hair.

  In addition to the amount of hair as described above, there are individual differences in the shape of the head. Therefore, when the reference electrode and the signal electrode are structured to extend in the longitudinal direction of the temple, each electrode and the temporal region may be in contact with each other over a relatively wide range or only in a relatively narrow range. In some cases, this also caused variations in communication performance.

  Furthermore, since there is a gap between the temple and the temporal region near the lens of the glasses, there is a problem that there are many portions that cannot be brought into contact with the human body even if the electrode extends over the entire length of the temple. there were.

  The present invention has been made in order to solve the above-mentioned problems, and the purpose thereof is to be able to be worn on the head, and at the time of wearing, the electrode can be placed in contact with or close to the human body more reliably than the conventional product. The object is to provide a communication device for human body communication.

Hereinafter, the configuration employed in the present invention will be described.
The communication device for human body communication according to the present invention changes the potential of the signal electrode relative to the potential of the reference electrode, so that a signal corresponding to the potential difference between the reference electrode and the signal electrode is transmitted to other devices. Transmitting and receiving a signal corresponding to the detected potential difference from the other device by detecting the potential difference generated between the reference electrode and the signal electrode when the signal is transmitted from the other device. At least one of them can be executed.

  Further, when the user wears the main body of the communication device on the head, the pair of reference electrodes and signal electrodes are at least one selected from the periphery of the nose, the periphery of the eyes, and the range from the cheek to the chin. In one range, a state in which the body is in contact with the human body or a state in which an inclusion having a predetermined dimension is sandwiched between the body and the human body is held at a position separated from the human body by a predetermined dimension.

  Therefore, if the electrode is in direct contact with the human body, unlike the conventional product that has an electrode that contacts the human side with hair, it is applied around the nose without hair, around the eyes, or from the cheek to the chin. An electrode can be brought into contact with the area.

  Alternatively, even when inclusions of a predetermined dimension are sandwiched between the electrode and the human body, in addition to the inclusions of a predetermined dimension, unlike conventional products in which even hair with individual differences is sandwiched, The electrode can be held at a position separated from the human body by a predetermined dimension in the area around the nose, around the eyes, or from the cheek to the chin. Therefore, regardless of whether the amount of hair is large, whether the hair is long, the shape of the head, etc., good communication performance can be ensured, and variations in communication performance can be suppressed.

  In the communication device of the present invention, in order to bring the electrode into contact with or close to the periphery of the nose, for example, the device body preferably has a structure as glasses. In this case, the reference electrode and the signal electrode are used by the user as glasses. It is good to incorporate in the nose pad which will contact the circumference | surroundings of a nose when mounting | wearing with a head.

  With such a communication device, since the nose pad closely contacts the periphery of the nose, the distance from the electrode to the skin is constant regardless of the hairstyle, physique, skeleton, etc., and stable communication performance is ensured. be able to.

  In addition, due to the weight of the glasses, moderate contact pressure is applied between the nose pad and the skin, and the nose pad is in close contact with the human body, enabling communication with low power and nose even when the user moves. The state in which the pad is in close contact with the human body can be maintained, and stable communication performance can be secured from this point.

  Furthermore, for the nose pad of glasses, the optimal shape has been studied for many years in consideration of adhesion and influence on the human body (discomfort / fatigue), so the electrodes included in the communication device of the present invention It is in a form suitable for incorporating. Therefore, compared with the case where the shape of the electrode is newly designed, the above-described adhesion and influence on the human body can be easily optimized, and the development cost can be reduced accordingly.

  Further, in the communication device of the present invention, in order to bring the electrode into contact with or close to the periphery of the eye, for example, it is preferable that the device body has a structure as goggles. It is good to be incorporated in a face pad that will come into contact with the periphery of the eye when worn on the head.

  With such a communication device, the face pad closely contacts the periphery of the eyes, so the distance from the electrode to the skin is constant regardless of the hairstyle, physique, skeleton, etc., and stable communication performance is ensured. be able to. Depending on the wearing state of the goggles and the hairstyle of the user, some hair may be caught between the upper part and the side part of the face pad, but it is usually difficult to think that the hair is caught across the entire face pad. In particular, it is originally used for applications that require airtightness, and in that case, it is usually mounted so as to be in direct contact with the skin, so that stable communication performance can be expected from this point.

  Moreover, since goggles are required to be airtight as described above, a soft material is used for the face pad. Therefore, with such a face pad, it will be in close contact with the skeleton, and it is difficult to form a part away from the skin, so a wider contact area can be secured, and with less power, Communication becomes possible.

  In addition, the goggles have a structure in which the face pad is pressed around the eyes by the pressure from the band applied to the back of the head, or when the goggles are subjected to water pressure or atmospheric pressure, the face pad is pressed by the pressure. Pressed around. Therefore, even if the user shows a violent movement, the adhesion of the face pad to the human body is not impaired, and thereby a stable communication state can be obtained and communication with low power is also possible.

  Further, in the communication device of the present invention, in order to bring the electrode into contact with or close to the range from the cheek to the chin, for example, the device body preferably has a structure as a full-face helmet, and in this case, the reference electrode and the signal electrode are When the user wears a full-face helmet on the head, it may be incorporated in a buffer pad that comes into contact with the range from the cheek to the chin.

  In such a communication device, the cushion pad is made of a soft material with elasticity and cushioning in order to reduce the impact on the head due to the structure of the helmet, and in the range from the cheek to the chin. Made into a close-fitting shape. For this reason, the buffer pad can be in close contact with the user's skeleton, and can be placed in close proximity to the cheek to chin with a relatively strong contact pressure. Thus, communication with low power becomes possible. In addition, the buffer pad can maintain a close contact state even during intense movement such as driving a motorcycle or the like, and a stable communication state can be obtained.

Next, embodiments of the present invention will be described with some specific examples.
[First Embodiment]
As shown in FIG. 1A and FIG. 1B, a communication device 1 for human body communication exemplified as the first embodiment of the present invention has a lens 2A as a device body that can be worn on the head of a user. , 2B and the frame 3 are provided.

  In this communication device 1, a pair of nose pads (portions shown by meshes in FIGS. 1A and 1B) attached to the frame 3 are made of a conductive material (for example, metal or conductive resin). The pair of nose pads is used as the reference electrode 5A and the signal electrode 5B. Moreover, the communication control part 7 is provided in one temple 3A among a pair of temple 3A, 3B with which the flame | frame 3 is provided.

  As shown in FIG. 1C, the communication control unit 7 includes a communication circuit 11 connected to the reference electrode 5A and the signal electrode 5B, and a microcomputer 13 (hereinafter abbreviated as a microcomputer 13) including a CPU, ROM, RAM, and the like. ). The communication circuit 11 includes a transmission circuit, a reception circuit, a switch for switching these circuits, and the like, and data transmission / reception by the communication circuit 11 is controlled by the microcomputer 13.

  The communication device 1 configured as described above can communicate with other devices via the user's body when the user wears the communication device 1. Specifically, the transmission / reception control of data by the communication control unit 7 can be executed. When the data transmission is executed, the communication control unit 7 sets the potential of the signal electrode 5B relative to the potential of the reference electrode 5A. Thus, control is performed to transmit a signal corresponding to the potential difference between the reference electrode 5A and the signal electrode 5B to another device. A signal transmitted by such control is transmitted to other devices via the user's body.

  Further, when receiving data in the communication device 1, the communication control unit 7 detects a potential difference generated between the reference electrode 5A and the signal electrode 5B when a signal is transmitted from another device. Then, control is performed to receive a signal corresponding to the detected potential difference from another device.

  According to the communication apparatus 1 configured as described above, the user can wear the head in the same manner as general glasses, and thereby, the reference electrode 5A having a structure equivalent to a nose pad and the signal The electrode 5B comes into close contact with the skin around the nose.

  Therefore, unlike glasses-type communication devices that incorporate electrodes in temples, the distance from the reference electrode 5A and the signal electrode 5B to the skin is constant regardless of the hairstyle, physique, skeleton, etc., ensuring stable communication performance. can do.

  Further, due to the dead weight of the communication device 1, an appropriate contact pressure is applied to the nose pad-like reference electrode 5A and the signal electrode 5B, and the nose pad-like reference electrode 5A and the signal electrode 5B are in close contact with the human body. Communication becomes possible. Further, even when the user moves, the nose pad-like reference electrode 5A and the signal electrode 5B can be kept in close contact with the human body, and stable communication performance can be secured from this point.

  Furthermore, as for the nose pad of glasses, the optimum shape has already been studied for many years in consideration of adhesion and influence on the human body (discomfort and fatigue). It is only necessary to adopt the same form as the nose pad. Therefore, compared with the case where the shape of the electrode is newly designed, the above-described adhesion and influence on the human body can be easily optimized, and the development cost can be reduced accordingly.

  The communication device 1 according to the first embodiment described above may be used for any purpose, and the use is not particularly limited. For example, the communication apparatus 1 may be used for other equipment installed as a fixed facility. When a user touches, when communicating with another apparatus via a user's body, it can utilize as a communication apparatus of the side which a user carries. In addition, two users each having the communication device 1 can also communicate with each other via the user's body by touching each other.

  In addition, there is no particular limitation on what data is transmitted from the communication device 1 or what data the communication device 1 receives when performing such communication. For example, the user ID for identifying can be transmitted, or data indicating that it has been authenticated can be received.

  However, since the communication device 1 is configured as a glasses-type device, it is more useful if the communication device 1 is configured so that human body communication can be used only for the glasses-type application. As an application unique to the eyeglass type, for example, data transmitted through the user's body is received, and text information and image information based on the received data are displayed on the lenses 2A and 2B.

  As a specific configuration for projecting text information and image information on the lenses 2A and 2B, the technology already filed by the applicant of the present application can be used. For example, Japanese Patent Laid-Open No. 9-46732 discloses Equivalent to the disclosed “face mount type display device”, “stereoscopic display device” disclosed in Japanese Patent Laid-Open No. 9-166762, “information display device” disclosed in Japanese Patent Laid-Open No. 2006-350934, etc. Technology can be adopted.

  By using these technologies, for example, text information and image information can be imaged in the space in front of the user using the parallax of the left eye and the right eye, so various information can be transmitted to the user. can do.

  Specifically, for example, it is possible to configure a technology that functions in exactly the same way as the technology described in each of the above-mentioned publications, and at that time, by using the glasses-type communication device 1, it is necessary in the conventional technology. Wired communication using cables and wireless communication using space can be replaced by human body communication.

  In addition to the techniques described in the above-mentioned publications, for example, when sports training is performed with the communication device 1 being worn, a portable type in which a user wears information such as instructions from a coach around the torso The information is received by the parent device, and information is transmitted from the portable parent device to the glasses-type communication device 1 via the user's body, and the information is reflected on the lenses 2A and 2B, thereby transmitting the instruction to the user. , And so on.

  Alternatively, for example, when shopping with the communication device 1 attached, product information is transmitted from the shopping cart touched by the user to the communication device 1 via the user's body, and the information is transmitted to the lens 2A, By projecting to 2B, product information can be transmitted to the user.

[Second Embodiment]
As shown in FIG. 2, the communication device 21 for human body communication exemplified as the second embodiment of the present invention includes lenses 22A and 22B, a frame 23A, and a band 23B as a device body that can be worn by the user on the head. It is a goggle type.

  In this communication device 21, the left and right side portions (portions shown by meshes in FIG. 2) of the face pad attached to the frame 23A are made of a flexible conductive material (eg, conductive sponge, conductive rubber). The face pad is used as the reference electrode 25A and the signal electrode 25B.

A communication control unit 27 is provided at the center of the frame 23A. The specific configuration of the communication control unit 27 is the same as that exemplified in the first embodiment.
According to the communication device 21 configured as described above, the user can wear the head in the same manner as general goggles, whereby the reference electrode 25A and the signal having a structure equivalent to a face pad can be obtained. The electrode 25B is in close contact with the skin around the eyes.

  Therefore, with such a communication device 21, the distance from the reference electrode 25A and the signal electrode 25B to the skin is constant regardless of the user's hairstyle, physique, skeleton, etc., and stable communication performance is ensured. Can do. Depending on the wearing state of the communication device 21 and the hairstyle of the user, there is a possibility that some hair may be caught between the upper part and the side part of the reference electrode 25A and the signal electrode 25B. Usually, however, the reference has a structure equivalent to a face pad. It is unlikely that the hair is pinched across the electrode 25A and the signal electrode 25B. In particular, this type of goggles is originally used for applications that require airtightness, and in that case, it is usually worn so as to be in direct contact with the skin, so that stable communication performance can be secured from this point. I can expect.

  In general, since goggles are required to be airtight as described above, a soft material is used for the face pad. Therefore, if the reference electrode 25A and the signal electrode 25B are made of a soft material equivalent to such a face pad, the reference electrode 25A and the signal electrode 25B are in close contact with each other along the skeleton, and a portion separated from the skin is difficult to be formed. The contact area can be ensured, and communication with low power is possible accordingly.

  Further, in the case of such a goggle type communication device 21, the reference electrode 25A and the signal electrode 25B are pressed around the eyes by the pressure from the band 23B applied to the back of the head, or the water pressure is applied to the goggle. Even when the air pressure is received, the face pad-like reference electrode 25A and the signal electrode 25B are pressed around the eyes by the pressure. Therefore, even if the user shows a violent movement, the adhesion of the reference electrode 25A and the signal electrode 25B to the human body is not impaired, and thereby a stable communication state can be obtained and communication with low power is also possible. It becomes.

  Note that the communication device 21 of the second embodiment described above can be arbitrarily used in the same application as that of the first embodiment. For example, text information is stored in a space in front of the user using the lenses 22A and 22B. And image information can be formed and various information can be transmitted to the user.

  Therefore, when configured as work goggles, information such as instructions and work manuals related to various tasks is transmitted from the various devices held in the hand to the communication device 21 via the user's body, and the information. Can be displayed.

  In addition, when configured as goggles for underwater, information such as the amount of air remaining in the cylinder is transmitted from the cylinder to the communication device 21 via the user's body, or each of the two users in the water possesses it. When exchanging information between users using the communication device 21, various visualized information can be transmitted to the users.

  Furthermore, when configured as riding goggles to be worn when riding a motorcycle or the like, map information and traffic information are transmitted from the navigation system mounted on the motorcycle body to the communication device 21 through the user's body, Visualized map information and traffic information can be transmitted to users.

[Third Embodiment]

  In this communication device 31, the face pads (portions shown by meshes in FIG. 3B) attached to the frames 33A and 33B are made of a flexible conductive material (for example, a conductive sponge or conductive rubber). The face pad is used as the reference electrode 35A and the signal electrode 35B.

A communication control unit 37 is provided at the left end of the frame 33B. The specific configuration of the communication control unit 37 is the same as that exemplified in the first embodiment.
According to the communication device 31 configured as described above, the user can wear the head in the same manner as general goggles, and thereby the reference electrode 35A having a structure equivalent to a face pad and the signal The electrode 35B comes into close contact with the skin around the eyes.

  Therefore, with such a communication device 31, the distance from the reference electrode 35A and the signal electrode 35B to the skin is constant regardless of the user's hairstyle, physique, skeleton, etc., and stable communication performance is ensured. Can do.

  In general, since goggles are required to be airtight as described above, a soft material is used for the face pad. Therefore, the reference electrode 35A and the signal electrode 35B made of a soft material equivalent to the face pad are in close contact with each other along the skeleton, and a portion separated from the skin is difficult to be formed. The contact area can be ensured, and communication with low power is possible accordingly.

  Further, in the case of such a goggle-type communication device 31, the reference electrode 35A and the signal electrode 35B are pressed around the eyes by the pressure from the band 33C applied to the back of the head, or the water pressure is applied to the goggles. Even when the air pressure is received, the face pad-shaped reference electrode 35A and the signal electrode 35B are pressed around the eyes by the pressure. Therefore, even if the user shows a violent movement, the adhesion of the reference electrode 35A and the signal electrode 35B to the human body is not impaired, so that a stable communication state is obtained and communication with low power is possible. It becomes.

In addition, the communication apparatus 31 of 2nd Embodiment demonstrated above can also be utilized arbitrarily in the use similar to 2nd Embodiment.

  In this communication device 41, a cheek pad provided to protect a range from the cheek to the chin among the buffer pads disposed on the inner side of the shell 43A (portion indicated by a mesh in FIG. 4B). Is made of a conductive material having a buffering property (for example, conductive urethane foam), and the cheek pad is used as the reference electrode 45A and the signal electrode 45B.

  Further, a communication control unit 47 is provided on the rear head side (back side) of the shell 43A. The specific configuration of the communication control unit 47 is the same as that exemplified in the first embodiment.

  According to the communication device 41 configured as described above, the user can put on the head in the same manner as a general full-face helmet, and thus, a structure equivalent to a buffer pad (cheek pad) can be obtained. The reference electrode 45 </ b> A and the signal electrode 45 </ b> B possessed are in close contact with the skin in the range from the cheek to the chin.

  Therefore, in such a communication device 41, the reference electrode 45A and the signal electrode 45B are in close contact with each other along the skeleton of the user, and contact the range from the cheek to the chin with a relatively strong contact pressure. Thus, stable communication performance can be obtained, and communication with low power becomes possible. In addition, the buffer pad can maintain a close contact state even during intense movement such as driving a motorcycle or the like, and a stable communication state can be obtained.

  Note that the communication device 41 of the fourth embodiment described above can be arbitrarily used in the same application as that of the first embodiment. For example, text information or an image is displayed in a space in front of the user using the shield 43B. Information can be imaged and various information can be transmitted to the user.

  As a technique for displaying information on the shield of the helmet, for example, a technique equivalent to the “vehicle navigation device” disclosed in Japanese Patent Application Laid-Open No. 2008-014783 can be employed. If such technology is used, map information and traffic information are transmitted from the navigation system mounted on the motorcycle body to the communication device 41 via the user's body, and the visualized map information and traffic information are transmitted to the user. Can be communicated to.

  For example, in the above embodiment, examples of materials constituting each electrode include metals, conductive resins, conductive sponges, conductive sponges, and conductive urethane foams. However, other conductive materials may be used. For example, a non-conductive base material surface coated with a conductive paint may be used as the electrode.

  Further, in the above-described embodiment, as in the technique described in Patent Document 1, only the reference electrode and the signal electrode are each configured to be in direct contact with the human body, but the technique described in Patent Document 2 is described. Thus, a configuration in which the electrode itself does not directly contact the human body may be employed.

  More specifically, for example, in each of the above-described embodiments, each electrode is covered with a coating having a predetermined thickness (corresponding to an inclusion having a predetermined dimension in the present invention), and the predetermined thickness is sandwiched between the coatings. The electrode may be held at a position separated from the human body by (a predetermined dimension). In this case, the electrode close to the human body with the film interposed therebetween may be used as the signal electrode, and the reference electrode may be disposed on the opposite side of the human body with the signal electrode interposed therebetween. Thus, the performance of the communication device can be improved.

  Further, in the above-described embodiment, the case where each communication device receives information transmitted through the user's body and displays the information on the lens or the shield has been described in detail. You may employ | adopt the structure which transmits information to another apparatus via this.

You may comprise so that the switching control of the information displayed on the shield 43B etc. may be performed using a voice control function.

  In addition, in each of the above embodiments, various specific forms have been exemplified as the form of the communication device. However, these specific forms are merely examples, and the communication device of the present invention can be mounted on the head. Thus, if the electrode can be placed in contact with or close to the human body more reliably than the conventional product at the time of wearing, it has a different form from the above-mentioned embodiments, and uses different from the above-mentioned embodiments It may be used in.

  For example, in the first embodiment, the eyeglass-type communication device 1 is illustrated. However, such eyeglass-type communication device 1 may be configured as strong light or dust even if it is configured as eyesight correction glasses. It may be configured as protective glasses for protecting the eyes from the eye.
