  The process of the vibration waveform comparison unit 47_1 will be described with reference to FIG. FIG. 5 is a diagram for explaining the processing of the vibration waveform comparison unit 47_1 in the first embodiment. In the same figure, a vibration waveform 53 extracted by the first electronic device 10_1 and a vibration waveform 53_2 extracted by the second electronic device 10_2 are shown, and the vibration waveform information thereof is the vibration waveform comparison unit 47_1.

  Specifically, for example, when the vibration comparison result Rv is 1 and the sound comparison result Rs is 1, that is, the determination unit 48 can consider that the vibration waveform for one second from the vibration start time t_1 is the same, and When the waveforms can be regarded as the same, it is considered that the second electronic device 10_2, which is another electronic device, has come into contact, and it is determined that the second electronic device 10_2, which is another electronic device, is a communication partner.

Then, the determination unit 48 outputs information indicating the determination result to the transmission control unit 42_2.

  FIG. 7 is a sequence diagram showing a processing flow of the information exchange system 1 in the first embodiment. Here, it is assumed that a wireless ad hoc network has already been established between the first electronic device 10_1 and the second electronic device 10_2. First, the first electronic device 10_1 accepts designation of image data to be transmitted (T101). Next, the first electronic device 10_1 is moved by the user to come into contact with the second electronic device 10_2. At that time, the first electronic device 10_1 detects vibration and sound when in contact with the second electronic device 10_2 (T102). Similarly, the second electronic device 10_2 detects vibration and sound when in contact with the first electronic device 10_1 (T102_2).

  Next, the first electronic device 10_1 detects a vibration start time t_1 that is the first time when a vibration exceeding the threshold Th1 is detected (T103). Next, the first electronic device 10_1 requests the second electronic device 10_2 for information indicating a vibration waveform for one second from the vibration start time t_1 and information indicating a sound waveform (T104).

Next, the first electronic device 10_1 extracts information indicating a vibration waveform for one second from the vibration start time t_1 (T105). Similarly, the second electronic device 10_1 extracts information indicating a vibration waveform for 1 second from the vibration start time t_1 (T105_2).
Next, the first electronic device 10_1 extracts information indicating a sound waveform for one second from the vibration start time t_1 (T106). Similarly, the second electronic device 10_2 extracts information indicating a sound waveform for 1 second from the vibration start time t_1 (T106_2).

Next, in response to a request from the first electronic device 10_1, the second electronic device 10_2 sends information indicating the vibration waveform for one second from the vibration start time t_1 and information indicating the sound waveform to the first electronic device 10_1. 10_1 is transmitted (T107).
Next, the first electronic device 10_1 compares the vibration waveform extracted by the device itself with the vibration waveform extracted by the second electronic device 10_2 (T108).

  Next, the first electronic device 10_1 compares the sound waveform extracted by itself with the sound waveform extracted by the second electronic device 10_1 (T109). Next, the first electronic device 10_1 determines whether the vibration waveform can be regarded as the same and the sound waveform can be regarded as the same (T110). When the vibration waveform can be regarded as the same and the sound waveform can be regarded as the same (T110 YES), the first electronic device 10_1 specifies the transmission destination of the image data to the second electronic device 10_2, and the image data is the second. To the electronic device 10_2 (T111). Above, the process of this sequence is complete | finished.

<Effect of the first embodiment>
As described above, when the first electronic device 10_1 of the present embodiment is in contact with the second electronic device 10_2, the vibration waveform at the time of contact and the sound waveform at the time of contact detected by the detection unit 20 of the own device are described. By comparing the waveform of the vibration at the time of contact and the waveform of the sound at the time of contact detected by the second electronic device 10b_2, respectively, the waveform of the vibration at the time of contact and the waveform of the sound at the time of contact can be regarded as the same. In this case, the second electronic device 10_2 is designated as the data transmission destination.

  According to this, the electronic device on the transmission side according to the present embodiment can specify the data transmission destination without having to set the data transmission destination in advance, so that it is possible to reduce the effort and time required for data transmission. it can. In addition, since the receiving-side electronic device according to the present embodiment does not need to be switched to the reception standby state in advance like infrared communication, it is possible to reduce time and effort for data reception.

  Further, the first electronic device 10_1 of the present embodiment detects a vibration waveform that can be regarded as the same as the vibration waveform detected by the own device, and generates a sound waveform that can be regarded as the same as the sound waveform detected by the own device. Since only the detected electronic device is determined to be a data transmission target, it is possible to prevent selection of a wrong data transmission destination. The effect will be described below with a specific example.

  For example, it is assumed that a wireless ad hoc network has already been established between the first electronic device 10_1, the second electronic device 10_2, and another third electronic device. When the first electronic device 10_1 senses vibrations of its own device, the first electronic device 10_1 is different from all the electronic devices connected to the network via the wireless ad hoc network, that is, different from the second electronic device 10_2. The third electronic device is requested for information indicating the vibration waveform for one second from the vibration time t_1 and information indicating the sound waveform.

In that case, when the first electronic device 10_1 and the second electronic device 10_2 come into contact with each other, if the third electronic device accidentally comes into contact with the table, the vibration waveform detected by the first electronic device 10_1 or When the sound waveform is compared with the vibration waveform or the sound waveform detected by the third electronic device, there may be a case where either one of the vibration waveform or the sound waveform coincides by chance.
However, since the probability that both the vibration waveform and the sound waveform match is lower than the probability that any one matches, the first electronic device 10_1 selects the wrong data transmission destination. Can be prevented.

  The first electronic device 10_1 of the present embodiment specifies the data transmission destination by comparing the vibration waveform at the time of contact detected by each electronic device with the sound waveform at the time of contact. This is not the only one. The first electronic device 10_1 specifies the data transmission destination by comparing only one of the waveforms of the vibration at the time of contact and the waveform of the sound at the time of contact detected by each electronic device. Also good.

  In addition, the first electronic device 10_1 of the present embodiment has a vibration start time t_1 at the time of contact detected by each electronic device and a vibration duration time T1 that is a time during which the vibration exceeds a predetermined threshold Th1. The destination of data may be specified by comparison. In that case, the second electronic device 10_2 may transmit information indicating the vibration start time t_1 and information indicating the vibration duration time T1 to the first electronic device 10_1. As a result, the information indicating the vibration start time t_1 and the information indicating the vibration continuation time T1 can be smaller in capacity than the information indicating the vibration waveform and the information indicating the extracted sound waveform. Since the amount of packets to be transmitted can be reduced, the time required for communication can be shortened. Further, the first electronic device 10_1 only has to compare information indicating the vibration start time t_1 and information indicating the vibration duration time T1, so that the amount of calculation is reduced as compared with the vibration waveform or the sound waveform. Can do. This is particularly effective when the number of candidate electronic devices to be communicated increases as in a modification of the first embodiment described later.

  In addition, the first electronic device 10_1 of the present embodiment has a sound start time t_2 that is a time when a sound detected by each electronic device first exceeds a predetermined threshold Th2, and a sound exceeds a predetermined threshold Th2. The data transmission destination may be specified by comparing the sound duration time T2, which is a certain time, respectively.

  Furthermore, the first electronic device 10_1 of the present embodiment combines the above to compare the vibration start time t_1, the vibration duration T1, the sound start time t_2, and the sound duration T2, respectively. May be specified. As a result, the first electronic device 10_1 determines that the second electronic device 10_2 is a data transmission destination when all four parameters of vibration and sound can be regarded as the same. The transmission target can be specified more accurately than the determination based on the above.

<Modification of First Embodiment>
In this embodiment, there is one electronic device that transmits data and one electronic device that receives data. However, the present invention is not limited to this, and one electronic device that transmits data receives one data. One or more electronic devices may be used.

  FIG. 8 is a configuration diagram of an information exchange system 1b in a modification of the first embodiment. The information exchange system 1b includes N i-th electronic devices 10_i (i) composed of a first electronic device 10_1, a second electronic device 10_2, a third electronic device 10_3,. Is an integer from 1 to N).

  Here, an example in which predetermined data (for example, image data) is transmitted from the first electronic device 10_1 to all other electronic devices will be described. Note that the electronic device that transmits the predetermined data is not limited to the first electronic device 10_1, and may be one of the electronic devices included in the information exchange system 1b.

  When the first electronic device 10_1, which is one of the electronic devices included in the information exchange system 1b, detects a vibration that exceeds a predetermined threshold, the first electronic device 10_1 It is determined whether or not the electronic device is a data transmission target. Then, the first electronic device 10_1 transmits the predetermined data to the electronic device determined as the data transmission target.

  When the first electronic device 10_1 transmits data, the device is moved by the user as shown in FIG. 8, and the device is the destination electronic device as shown in FIG. Or an electronic device as a transmission destination with another electronic device interposed therebetween.

  Here, as an example in which the transmission-side electronic device is in contact with the transmission-destination electronic device with another electronic device interposed therebetween, in FIG. 8, the third electronic device 10_3 is changed to the first electronic device 10_1. It is shown that the second electronic device 10_2 is sandwiched between the first electronic device 10_1 and the third electronic device 10_3 without being in direct contact.

In this manner, the receiving-side electronic device is not only in direct contact with the first-side electronic device 10_1 that is the transmitting-side electronic device, but the other electronic device is sandwiched between the electronic devices on the transmitting side. The vibration of the first electronic device 10_1 may be in a relationship in which the vibrations of the second to Nth electronic devices on the receiving side are transmitted to each other.
If the material and the outer shape of the housing of each i-th electronic device 10_i are configured to be the same, the vibration detection unit included in each electronic device when touched can detect the vibrations that can be regarded as the same. Waveform can be detected.
In addition, since each i-th electronic device 10_i is in a close position, the sound detectors included in each i-th electronic device 10_i can detect sound waveforms that can be regarded as the same when they come into contact.

When the first electronic device 10b1, which is one of the electronic devices included in the information exchange system 1b, detects a vibration that exceeds a predetermined threshold, the first electronic device 10_1
The vibration waveform and sound waveform detected by the device itself are sequentially compared with the vibration waveform and sound waveform detected by the other N−1 electronic devices (10_2 to 10b_N).

In addition, since the receiving-side electronic device according to the present embodiment does not need to be switched to the reception standby state in advance like infrared communication, it is possible to reduce time and effort for data reception.

Consider a case where it is assumed that a wireless ad hoc network has already been established among N electronic devices from the first electronic device 10_1 to the Nth electronic device 10_N. In that case, when the first electronic device 10_1 touches only the i-th electronic device 10_i that the user wants to transmit data by the user, the first electronic device 10_1 contacts the i-th electronic device Data can be transmitted only to 10_i.
Thereby, the user who uses the first electronic device 10_1 can transmit data to a specific electronic device without being known by the user who uses the other i-th electronic device 10_i.

<Second Embodiment>
Next, the second embodiment will be described. FIG. 9 is a configuration diagram of the information exchange system 2 in the second embodiment. The information exchange system 1b includes a first electronic device 10b_1 and a second electronic device 10b_2. In the figure, in the xyz coordinate system, when the first electronic device 10b_1 and the second electronic device 10b_2 collide, a collision target position 71 that is a target of the collision is shown.

  The collision target position 71 is located at the intersection of the collision target straight line L_1 and the collision target straight line L_2. Further, the side surface SD1 of the housing closest to the collision target position P_1 of the first electronic device 10b_1 and the side surface SD2 of the housing closest to the collision target position P_2 of the second electronic device 10b_2 are shown. .

  First, an outline of the information exchange system 2 in the second embodiment will be described. In the first embodiment described above, when the first electronic device 10_1 and the second electronic device 10_2 are brought into contact with each other, the first electronic device 10_1 vibrates at the time of contact detected by each electronic device. The destination of the data was specified by comparing the waveform of and the waveform of the sound at the time of contact.

  In the second embodiment, the side surface SD1 of the first electronic device 10b_1 is directed toward the collision target position 71 and the side surface SD2 of the second electronic device 10b_2 is directed toward the collision target. In that case, when the first electronic device 10b_1 and the second electronic device 10b_2 are brought into contact with each other, the first electronic device 10b_1 and the second electronic device 10b_2 are in the direction of a certain collision target position 71. The first electronic device 10b_1 identifies the second electronic device 10b_2 as a data transmission destination.

Next, the first electronic device 10b_1 in the second embodiment will be described. Note that the second electronic device 10b_2 has the same configuration as the first electronic device 10b_1, and thus the description thereof is omitted. FIG. 10 is a block configuration diagram of the electronic device 10b_1 according to the second embodiment. Elements common to those in FIG. 1 are denoted by the same reference numerals, and detailed description thereof is omitted.
The configuration of the electronic device 10b_1 in FIG. 10 is different from the configuration of the electronic device 10_1 in FIG. 1 in that the detection unit 20 is changed to the detection unit 20b and the control unit 40 is changed to the control unit 40b.

Compared to the detection unit 20, the detection unit 20 b includes an azimuth detection unit 23 and a position detection unit 24.
The azimuth detector 23 is, for example, an azimuth sensor that detects the azimuth from the geomagnetism using a Hall element. The azimuth detection unit 23 detects the azimuth that the device is facing, and outputs information on the detected azimuth to a collision position extraction unit 94 described later of the control unit 40b.

  Specifically, for example, the azimuth detecting unit 23 is a side surface of the housing and is closest to the collision target position in a predetermined coordinate system (for example, a coordinate system having latitude, longitude, and gravity directions as axes). The normal direction of the side surface SD1 is detected as an azimuth, and information indicating the detected azimuth is output to the control unit 40b.

  The position detection unit 24 detects the position of the own device and outputs information indicating the detected position of the own device to a position extraction unit 93 described later of the control unit 40b. The position detection unit 24 is, for example, a gyro sensor.

  Compared with the control unit 40, the control unit 40b includes a position extraction unit 93 and a collision position extraction unit 94, the comparison unit 47 is changed to a comparison unit 47b, the determination unit 48 is changed to a determination unit 48b, The vibration waveform extraction unit 45 and the sound waveform extraction unit 46 are removed.

  The position extraction unit 93 extracts the position of the own device at the vibration start time t_1 from the information indicating the position of the own device input by the position detection unit 24, and indicates the position of the own device at the extracted vibration start time t_1. Is output to the collision target straight line calculation unit 94.

The collision target straight line calculation unit 94 extracts the orientation of the terminal detected by the orientation detection unit 23 at the vibration start time t_1 extracted by the contact determination unit 31.
The collision target straight line calculation unit 94 is based on the information indicating the orientation of the extracted vibration start time t_1 and the information indicating the position of the own device at the vibration start time t_1 input from the position extraction unit 93. The collision target straight line where the collision target position that becomes the target with which the electronic device collides exists is calculated.

  Specifically, the collision target straight line calculation unit 94 calculates a straight line in the direction of the direction of the vibration start time t_1 as the collision target straight line from the position of the vibration start time t_1. And the collision target straight line calculation part 94 outputs the information which shows the collision target straight line L_1 to the straight line intersection determination part 95 mentioned later of the comparison part 47b.

  The comparison unit 47b includes a straight line intersection determination unit 95. The straight line intersection determination unit 95 receives information indicating the collision target straight line L2 calculated by the second electronic device 10b_2 via the communication unit 32. The straight line intersection determination unit 95 determines whether or not the calculated collision target straight line L_1 and the collision target straight line L_2 calculated by the second electronic device 10b_2 which is another electronic device intersect in a predetermined position range.

  Specifically, for example, when the two collision target straight lines intersect in a predetermined position range, the straight line intersection determination unit 95 sets the intersection determination result Rd to 1 and the two collision target straight lines do not intersect in the predetermined position range. The intersection determination result Rd is set to 0. And the information Rd which shows the intersection determination result is output to the determination part 48b.

If the determination unit 48b determines that the straight intersection determination unit 95 of the comparison unit 47 intersects, the determination unit 48b determines whether or not the second electronic device 10b_2 whose own device is another electronic device is a communication partner.
Specifically, for example, when the intersection determination result Rd is 1, that is, when two collision target straight lines intersect in a predetermined position range, the determination unit 48b is a second electronic device whose own device is another electronic device. 10b_2 and the communication partner. Thereby, the determination part 48b can specify the data transmission object to 2nd electronic device 10b_2 which is another electronic device.

  On the other hand, when the intersection determination result Rd is 0, that is, when the two collision target straight lines do not intersect within the predetermined position range, the determination unit 48b contacts the second electronic device 10b_2 that is another electronic device. Judge that there was no. Then, the determination unit 48b outputs information indicating the determination result to the transmission control unit 42_2.

  FIG. 11 is a sequence diagram showing the flow of processing of the information exchange system 2 in the second embodiment. Here, it is assumed that a wireless ad hoc network has already been established between the first electronic device 10b_1 and the second electronic device 10b_2.

Similarly, the second electronic device 10_2 detects a vibration at the time of contact with the first electronic device 10_1 (T202_2).

  Next, the first electronic device 10b_1 detects a vibration start time t_1 that is the first time at which a vibration exceeding the threshold Th1 is detected (T203). Next, the first electronic device 10b_1 requests information indicating the collision target straight line from the second electronic device 10b_2 (T204).

  Next, the first electronic device 10b_1 calculates information indicating the collision target straight line (T205). Similarly, the second electronic device 10b_1 calculates information indicating the collision target straight line (T205_2).

Next, in response to a request from the first electronic device 10b_1, the second electronic device 10b_2 transmits information indicating the collision target straight line to the first electronic device 10b_1 (T206).
Next, the first electronic device 10b_1 determines whether or not the collision target straight line calculated by itself and the collision target straight line calculated by the second electronic device 10b_2 intersect within a predetermined position range (T207). .

  When the collision target straight lines intersect with each other in a predetermined position range (T207 YES), the first electronic device 10b_1 specifies the transmission destination of the image data as the second electronic device 10b_2, and the image data is transmitted to the second electronic device 10b_2. (T208). Above, the process of this sequence is complete | finished.
