A plurality of communication devices 2,... Are installed at home, for example, and can communicate with the glasses-type communication terminal 1 via a wireless communication line (for example, a wireless PAN (Personal Area Network) such as Bluetooth (registered trademark)). It has become.

First, the glasses-type communication terminal 1 will be described with reference to FIGS.
FIG. 2 is a perspective view showing a state in which the glasses-type communication terminal 1 is mounted on the head of the user M. FIG. 3 is a block diagram illustrating a schematic configuration of the glasses-type communication terminal 1.

  As shown in FIG. 2, the glasses-type communication terminal 1 is a so-called wearable computer system worn by a user M, and particularly a head-mounted computer system (head-mounted display). More specifically, the glasses-type communication terminal 1 is configured to be worn on the head like glasses.

As shown in FIG. 3, the glasses-type communication terminal 1 includes a central control unit 101, a memory 102, a storage unit 103, an imaging unit 104, a display unit 105, a positioning processing unit 106, and a device specifying unit 107. A communication control unit 108, an operation input unit 109, and the like.
The central control unit 101, the memory 102, the storage unit 103, the imaging unit 104, the display unit 105, the positioning processing unit 106, the device specifying unit 107, and the communication control unit 108 are connected via a bus line 110.

  The central control unit 101 controls each unit of the glasses-type communication terminal 1. Specifically, although not shown, the central control unit 101 includes a CPU (Central Processing Unit), a RAM (Random Access Memory), and a ROM (Read Only Memory), and various processing programs for the glasses-type communication terminal 1. Various control operations are performed in accordance with (not shown).

  The memory 102 is configured by, for example, a DRAM (Dynamic Random Access Memory) or the like, and temporarily stores data processed by each unit of the glasses-type communication terminal 1 in addition to the central control unit 101.

  The memory | storage part 103 is comprised from SSD (Solid State Drive) etc., for example, and memorize | stores various information. Specifically, the storage unit 103 stores communication device data 103a.

The communication device data 103a is data related to the communication device 2 connected so as to be capable of information communication. Specifically, for example, the communication device data 103a includes, for example, names of a plurality of communication devices 2 (for example, communication devices A1 to A3) that are connected so as to be capable of information communication, and information on each communication device 2. The identification information is associated with the position information of each communication device 2.
The position information is information including coordinates (for example, latitude, longitude, altitude, etc.) of the position where each communication device 2 is disposed.
As described above, the storage unit 103 constitutes storage means in which specific information including position information of at least one communication device 2 capable of information communication is stored.

The communication device data 103a may be stored in association with an index (for example, an icon or the like; not shown) that is displayed on the display unit 105 and can identify the communication device 2, for example.
Further, the data configuration of the communication device data 103a and the communication device 2 capable of information communication are merely examples and are not limited thereto, and can be arbitrarily changed as appropriate. For example, information related to communication devices (not shown) arranged in places other than home (for example, workplaces, commercial facilities, event venues, vehicles, etc.) may be stored.

  The imaging unit (imaging unit) 104 images a range corresponding to the field of view A (see FIG. 1 and the like) of the user M wearing the glasses-type communication terminal 1 main body. Specifically, for example, the imaging unit 104 includes a lens unit, an electronic imaging unit, and an imaging control unit (not shown).

The lens unit includes a plurality of lenses (not shown) such as a zoom lens and a focus lens.
The electronic imaging unit includes, for example, an image sensor (not shown) such as a CCD (Charge Coupled Device) or a CMOS (Complementary Metal-oxide Semiconductor), and an optical image passing through various lenses of the lens unit is converted into a two-dimensional image signal. Convert to

  The imaging control unit includes, for example, a timing generator, a driver, and the like (not shown). Then, the imaging control unit scans and drives the electronic imaging unit with a timing generator and a driver, converts an optical image formed by the lens unit at predetermined intervals into a two-dimensional image signal with the electronic imaging unit, and A frame image is read from the imaging area of the electronic imaging unit for each screen and is output to the memory 102. Each frame image is sequentially processed by an image processing unit (not shown) and converted into a digital luminance signal Y and color difference signals Cb, Cr (YUV data).

In addition, the imaging unit 104 includes a line-of-sight direction estimation unit 104a.
The line-of-sight direction estimation unit (estimating unit) 104a estimates the direction of the line of sight E of the user M. That is, the gaze direction estimation unit 104 a estimates the frame image captured by the imaging unit 104 as a range corresponding to the field of view A of the user M. Then, the line-of-sight direction estimation unit 104a estimates the direction toward the predetermined position within the estimated range as the direction of the line of sight E of the user M. Specifically, the line-of-sight direction estimation unit 104a uses the reference position (for example, the center) in the frame image that is a range corresponding to the field of view A captured by the imaging unit 104 and the eyeglass-type communication terminal 1 main body as a head. A straight line passing through the position of the pupil of the user M assumed from the posture attached to the part is specified. Then, the line-of-sight direction estimation unit 104a estimates the direction of the identified straight line as the direction of the line of sight E of the user M.

  Note that the above-described method for estimating the direction of the line of sight E of the user M is an example, and is not limited thereto, and can be arbitrarily changed as appropriate. For example, by detecting the gravity axis direction and the inclination of each axis with respect to the gravity axis direction using a three-axis acceleration sensor (not shown), the inclination of the glasses-type communication terminal 1 main body is specified, and the specified glasses type The direction of the line of sight E of the user M may be estimated in consideration of the inclination of the communication terminal 1 main body, or the front direction of the eyeglass-type communication terminal 1 may be simply set as the direction of the line of sight E of the user M.

The display unit 105 superimposes the light of the image and the light of the external image corresponding to the field of view A, and transmits and displays them in the display area.
Specifically, the display unit 105 includes an optical element disposed in front of the lens of the spectacle body 1a. The optical element is a holographic optical element, and light of an external image in front of the user M passes through the optical element and reaches the pupil of the user M, and an image (not shown) generated by a display control unit (not shown). For example, light of related information) is guided (diffracted and reflected) to the pupil of the user M by the optical element. Therefore, the light of the external world image and the light of the video are superimposed, and the external world image and the video are synthesized and reflected on the pupil of the user M.

The display unit 105 receives the video signal generated by the display control unit, and generates (displays) a video based on the video signal. For example, the display unit 105 includes a display controller, a display element (for example, a spatial light modulation element such as a liquid crystal display element or a digital micromirror device), and a light source device (not shown). The display controller controls the light source device and the display element based on the video signal, the light source device irradiates the display element with primary color light (for example, red light, blue light, and green light), and the display element is driven by the display controller. Thus, the light applied to the display element is modulated and controlled for each pixel. As a result, an image is generated by the display element. Note that if the display element of the display unit 105 is a time-emitting display element, the light source device is not provided in the display unit 105.
The video generated by the display unit (in particular, the display element) 105 is projected onto the pupil of the user M by the optical element and the projection lens.

The positioning processing unit 106 measures the current position of the glasses-type communication terminal 1 main body using, for example, a GNSS (Global Navigation Satellite System) such as GPS (Global Positioning System).
That is, the positioning processing unit 106, for example, signals transmitted from a plurality of positioning satellites S launched in low earth orbit (for example, positioning codes such as C / A (Coarse and Acquisitions) code and P (Precise) code), Almanac information (schematic trajectory information) and ephemeris information (detailed trajectory information) are received by the receiving antenna 106a at a predetermined timing.

The positioning unit 106b of the positioning processing unit 106 measures, for example, the three-dimensional current position (latitude, longitude, altitude) of the glasses-type communication terminal 1 main body in the three-dimensional positioning mode based on the signal received by the receiving antenna 106a. Perform the positioning process. Specifically, the positioning unit 106b calculates a position of each positioning satellite S by performing a predetermined calculation based on a navigation message (for example, ephemeris information) included in a signal received by the receiving antenna 106a. For example, in the case of the three-dimensional positioning mode, the positioning unit 106b calculates pseudorange information corresponding to each of the four or more positioning satellites S, and then performs a predetermined calculation based on the position of each positioning satellite S. Thus, the three-dimensional coordinates (x, y, z) of the current position where the glasses-type communication terminal 1 main body exists, the error of the clock of the glasses-type communication terminal 1 main body, and the like are calculated. Thus, the positioning part 106b detects the present position where the spectacles type communication terminal 1 main body exists as a detection means.
Further, the positioning processing unit 106 may output the position information of the current position of the glasses-type communication terminal 1 main body generated by the positioning unit 106 b to the memory 102.

The device specifying unit 107 specifies a communication target capable of information communication with the glasses-type communication terminal 1.
That is, the device specifying unit 107 can communicate based on the direction of the line of sight E of the user M estimated by the line-of-sight direction estimation unit 104a and the current position of the glasses-type communication terminal 1 main body detected by the positioning processing unit 106. A communication target is specified from the detected communication devices 2. Specifically, the device specifying unit 107 determines the spectacles based on the direction of the line of sight E of the user M estimated by the line-of-sight direction estimation unit 104 a and the current position of the glasses-type communication terminal 1 main body detected by the positioning processing unit 106. The field of view A (corresponding to the fan-shaped range in FIG. 1) of the user M relative to the current position of the main body of the type communication terminal 1 is specified. Further, the device specifying unit 107 is based on the current position of the glasses-type communication terminal 1 main body detected by the positioning processing unit 106 and the position information of each communication device 2 stored in the communication device data 103 a of the storage unit 103. Then, the relative position and the relative direction of each communication device 2 with respect to the glasses-type communication terminal 1 are calculated. Then, the device specifying unit 107 is regarded as having entered the field of view A of the user M from at least one communication device 2 detected as communicable based on the calculated relative position and relative direction of each communication device 2. Communication device 2 (for example, communication device A2) is identified as a communication target.
Note that the communication device 2 detected as communicable here is not limited to the communication device 2 stored in the storage unit 103 but may be detected even if the communication device 2 is not stored in the storage unit 103. May be.

  Note that the above-described method for specifying a communication target is an example, and is not limited thereto, and can be arbitrarily changed as appropriate. For example, the device specifying unit 107 extracts the communication device 2 by performing image processing such as predetermined feature extraction processing (for example, edge extraction processing) on the image data of each frame image captured by the imaging unit 3. You may specify. In addition, the device specifying unit 107 considers the time zone based on the current time measured by the time measuring unit (not shown), and, for example, in the early morning, the user M wants to check the news. A process may be performed in which televisions, audio devices, and PCs are specified targets, and devices that do not transmit news are excluded from the specified targets.

The communication control unit 108 performs communication control of information with an external device such as the communication device 2 connected via a predetermined wireless communication line (for example, a wireless PAN (Personal Area Network) such as Bluetooth).
Specifically, the communication control unit 108 includes, for example, a control module for performing wireless communication with the communication device 2 via the communication antenna 108a. For example, the communication control unit 108 performs communication setting processing called pairing in advance, thereby exchanging device information and authentication key data with a communication partner using a wireless signal. As a result, even if the communication setting process is not performed every time thereafter, for example, if the glasses-type communication terminal 1 and the communication partner are separated from each other within a range where the radio wave does not reach, the communication connection is released, while the communication connection is canceled. Communication connection is automatically established. For example, the communication control unit (communication control unit) 108 uses the communication device 2 (for example, the communication device A2) identified as the communication target by the device specifying unit 107 as being considered to have entered the field of view A of the user M as a communication partner. A communication setting process is performed, and the communication device 2 is connected so that information communication is possible.

  Here, the Bluetooth communication standards include “1.x”, “2.x”, “2.x + EDR”, “3.x”, which are different in communication speed, applicable profile type (not shown), and the like. , “3.x + EDR”, “3.x + HS”, “4.x”, and the like. Although a detailed description of these versions is omitted, the communication control unit 108, for example, is “2.x + EDR”, which is one of the versions called “Bluetooth Classic” having backward compatibility, and other versions. It supports both functions of “4.x”, which is a version called “Bluetooth Low Energy (BLE)” that is not compatible. Then, the communication control unit 108 performs communication with the communication device 2 based on the “2.x + EDR” standard (“Bluetooth Classic”) in consideration of the communication speed, power saving performance, and the like.

  The communication control unit 108 is composed of, for example, a wireless LAN module and operates in a peer-to-peer (ad hoc mode) that directly establishes a wireless communication line with the communication device 2 without going through an external access point. You may do it.

The operation input unit 109 is for inputting various instructions to the glasses-type communication terminal 1 main body.
Specifically, the operation input unit 109 includes various buttons (such as a power button for turning on / off the power of the glasses-type communication terminal 1 main body, and up / down / left / right cursor buttons and a determination button for selecting instructions such as modes and functions). All of them are not shown).
When various buttons are operated by the user, the operation input unit 109 outputs an operation instruction corresponding to the operated button to the central control unit 101. The central control unit 101 causes each unit to execute a predetermined operation in accordance with an operation instruction output from the operation input unit 109 and input.

Next, the communication device 2 will be described.
The communication device 2 may be any device that can communicate information with the glasses-type communication terminal 1 via a wireless communication line (for example, a wireless PAN such as Bluetooth). That is, the communication device 2 includes a control module (not shown) for performing Bluetooth communication in substantially the same manner as the communication control unit 108 provided in the above-described glasses-type communication terminal 1.

  Moreover, as the communication apparatus 2 (for example, communication apparatus A1-A3 etc.) arrange | positioned at home, a television, an audio apparatus, PC, a weight scale, a body fat rate meter, a heart rate monitor, a blood pressure meter, an automatic washing type, for example A toilet (none of which is not shown) can be mentioned, but it is an example, and the present invention is not limited thereto, and can be arbitrarily changed as appropriate.

<Communication control processing>
Next, communication control processing by the communication control system 100 will be described with reference to FIG.
FIG. 4 is a flowchart illustrating an example of an operation related to the communication control process.

As shown in FIG. 4, first, in the eyeglass-type communication terminal 1, the line-of-sight direction estimation unit 104a estimates the frame image captured by the imaging unit 104 as a range corresponding to the field of view A of the user M, and estimates A direction toward a predetermined position (for example, the center) within the range is estimated as the direction of the line of sight E of the user M (step S1).
Subsequently, the positioning unit 106b of the positioning processing unit 106 determines the three-dimensional current position of the glasses-type communication terminal 1 main body based on the signal received by the receiving antenna 106a, and generates position information (step S2). .

  The order of the direction of the line of sight E of the user M in step S1 and the positioning of the current position of the main body of the glasses-type communication terminal 1 in step S2 are examples and are not limited to this. There may be.

  Next, the device identification unit 107 identifies the field of view A of the user M based on the current position of the glasses-type communication terminal 1 main body based on the direction of the line of sight E of the user M and the current position of the glasses-type communication terminal 1 main body. (Step S3). Subsequently, the device specifying unit 107 reads out and acquires the communication device data 103a from the storage unit 103, and acquires the position information of each communication device 2 (for example, communication devices A1 to A3) and the current state of the glasses-type communication terminal 1 main body. Based on the position information of the position, the relative position and relative direction of each communication device 2 with respect to the eyeglass-type communication terminal 1 are calculated (step S4).

The device specifying unit 107 then selects the user from the communication devices 2 (for example, communication devices A1 to A3) detected as currently communicable based on the calculated relative position and relative direction of each communication device 2. It is determined whether or not the communication device 2 exists in the M field of view A (step S5). For example, when the field of view A of the user M is in a range indicated by a two-dot chain line in FIG. 1, no communication device 2 exists in the field of view A of the user M. On the other hand, when the user M rotates his / her head in the right direction and the field of view A of the user M is in a range as indicated by the one-dot chain line in FIG. 1, the communication device A2 exists in the field of view A of the user M.
If it is determined in step S5 that the communication device 2 does not exist in the field of view A of the user M (step S5; NO), the CPU of the central control unit 101 returns the process to step S1, and the subsequent processes. Execute. That is, in step S1, the line-of-sight direction estimation unit 104a estimates the direction of the line of sight E of the user M, and in step S2, the positioning unit 106b measures the current position of the glasses-type communication terminal 1 main body. In step S3, the device specifying unit 107 specifies the field of view A of the user M with reference to the current position of the main body of the glasses-type communication terminal 1, and in step S4, each communication device for the glasses-type communication terminal 1 is specified. 2 relative position and relative direction are calculated.
Each of the above processes is repeatedly executed until it is determined in step S5 that the communication device 2 exists in the field of view A of the user M (step S5; YES).

On the other hand, if it is determined in step S5 that the communication device 2 is present in the field of view A of the user M (step S5; YES), the device identification unit 107 determines that the communication device 2 exists in the field of view A of the user M (for example, , Communication device A2 or the like) as a candidate for communication, the identification information of the communication device 2 is output to the display unit 105, and the display unit 105 displays an index (for example, an icon) corresponding to the input identification information of the communication device 2 Etc.) is acquired from the communication device data 103a and displayed (step S6).
Next, the CPU of the central control unit 1 determines whether or not an instruction to communicate with the communication device 2 corresponding to the index displayed on the display unit 105 as a candidate for communication is input (step S7). . Here, the input of the instruction to be communicated may be performed based on a predetermined operation of the operation input unit 109 by the user M, or the line of sight of the user M overlaps the index using a GUI (graphical user interface) or the like. This may be performed by detecting the fact, or may be performed using voice input or the like.

If it is determined in step S7 that the instruction to communicate with the communication device 2 corresponding to the index is not input (step S7; NO), the CPU of the central control unit 101 returns the process to step S1, Each subsequent process is executed.
On the other hand, when it is determined in step S7 that an instruction to communicate with the communication device 2 corresponding to the index is input (step S7; YES), the communication control unit 108 receives an instruction to communicate. Communication setting processing (for example, pairing or the like) is performed with the communication device 2 (for example, the communication device A2) as a communication partner, and wireless communication is established with the communication device 2 so that information communication is possible (step S8).

  Note that the wireless communication between the glasses-type communication terminal 1 and the communication device 2 (for example, the communication device A2) is, for example, within a range where the glasses-type communication terminal 1 and the communication device 2 do not reach radio waves, or new communication. It is canceled by wirelessly connecting to the device 2 (for example, the communication device A1 or the like) so that information communication is possible.

  As described above, according to the communication control system 100 of the present embodiment, the glasses-type communication terminal 1 includes the direction of the line of sight E of the user M, the current position of the glasses-type communication terminal 1 main body, and the communication device data in the storage unit 103. Based on the specific information of at least one communication device 2 stored in 103a, when it is considered that one communication device 2 has entered the field of view A of the user M, information communication with the one communication device 2 is possible. Since the connection is made, the direction of the line of sight E of the user M is estimated, and the communication device 2 (for example, the communication device A2 etc.) capable of information communication only by detecting the current position of the glasses-type communication terminal 1 main body is specified and connected. can do. That is, the communication device 2 can be identified and connected so as to be able to communicate information only by directing the line of sight E of the user M to the communication device 2 desired by the user who wants to communicate information with the glasses-type communication terminal 1. Therefore, there is no possibility of erroneous operation depending on the accuracy of the line-of-sight detection as in the prior art, and information communication between the glasses-type communication terminal 1 and the communication device 2 can be easily performed.

  Further, since the range corresponding to the field of view A of the user M is estimated and the direction toward the predetermined position in the range is estimated as the direction of the line of sight E of the user M, the direction of the line of sight E of the user M is appropriately estimated. be able to. Specifically, for example, by using the glasses-type communication terminal 1 configured to be worn on the head of the user M, the range corresponding to the field of view A of the user M is captured, so that an image of the captured range is obtained. Based on this, the direction of the line of sight E of the user M can be estimated accurately and easily.

The present invention is not limited to the above-described embodiment, and various improvements and design changes may be made without departing from the spirit of the present invention.
For example, in the above-described embodiment, at least one communication device 2 connected so as to be capable of information communication is stored as communication device data 103a in association with the position information. For example, the communication device data 103a is stored in an external device (for example, an external server or the like; not shown), and the glasses-type communication terminal 1 communicates with the external device to identify a communication target. Such a configuration may be adopted.

  If it is determined in step S7 of the communication control process in FIG. 4 that an instruction to communicate with the communication device 2 corresponding to the index is input, the communication control unit 108 receives the instruction to communicate. The communication setting process is performed using the input communication device 2 as a communication partner, and wireless connection is established with the communication device 2 so as to perform information communication. However, the communication device 2 is an example, and the communication corresponding to the index is not limited thereto. A wireless connection may be automatically established with the device 2 so that information communication is possible.

Further, the configuration of the communication control system 100 and the configuration of the eyeglass-type communication terminal (communication control device) 1 included in the communication control system 100 are merely examples, and are not limited thereto.
That is, instead of the glasses-type communication terminal 1, for example, a smartphone, a mobile phone, a PHS (Personal Handy-phone System), a PDA (Personal Data Assistants), or the like may be applied. Moreover, in the said embodiment, although the spectacles type | mold communication terminal 1 which can be mounted | worn on the user's M head was illustrated, the structure which can be mounted | worn to the other site | part (for example, a shoulder, a chest, etc.) of the user M, for example. It may be.

  Moreover, in the said embodiment, although what was arrange | positioned at home was illustrated as the communication apparatus 2, it is an example and it is not restricted to this, It can change arbitrarily arbitrarily. That is, for example, it may be a communication device (not shown) disposed in the workplace such as a PC, a tablet terminal, a keyboard, a mouse, a printer (all not shown), or “i-Beacon (registered trademark)”. Beacon transmitters such as tags, communication equipment (not shown) installed in event venues such as stores (commercial facilities) where this transmitter is installed, public facilities, equipment, seats, products (all not shown) There may be. Moreover, the communication apparatus (illustration omitted) mounted in vehicles, such as a motor vehicle, a train, and an airplane, may be sufficient.

In addition, in the above-described embodiment, the functions as the estimation unit, the detection unit, and the communication control unit are controlled by the central control unit 101 of the glasses-type communication terminal 1, and the line-of-sight direction estimation unit 104a and the positioning unit 106b. However, the configuration is realized by driving the communication control unit 108. However, the configuration is not limited to this, and may be realized by executing a predetermined program or the like by the central control unit 101.
That is, a program including an estimation processing routine, a detection processing routine, and a communication control processing routine is stored in a program memory (not shown). Then, the CPU of the central control unit 101 may function as a means for estimating the direction of the line of sight E of the user M by an estimation processing routine. Further, the CPU of the central control unit 101 may function as a means for detecting the current position by a detection processing routine. Further, the communication control processing routine allows the CPU of the central control unit 101 to change one communication device based on the estimated direction of the line of sight E, the detected current position, and the stored specific information of at least one communication device 2. When 2 is considered to have entered the field of view A of the user M, it may function as a means for connecting to one communication device 2 so as to be able to communicate information.
