  FIG. 1 is a diagram showing a configuration of a wireless communication system according to the present embodiment. The wireless communication system includes a plurality of communication terminals 1 each being a communication device and a server 2 being an information processing device. Each of the plurality of communication terminals 1 and the server 2 perform wireless communication with each other via the base station 3. First, an outline of the radio communication system according to the present embodiment will be described. In the following description, among the plurality of communication terminals 1, one communication terminal 1 that transmits data may be referred to as a transmission source terminal 4, and a communication terminal 1 other than the transmission source terminal 4 may be referred to as another communication terminal 5.

  Each of the plurality of communication terminals 1 acquires position information for specifying the position of the own terminal, and transmits the position information to the server 2. The server 2 generates a map that specifies the positional relationship between the communication terminals 1 based on the position information transmitted from each of the plurality of communication terminals 1.

  The user performs an operation of rubbing at a predetermined speed or more toward the data transmission destination among the plurality of communication terminals 1 excluding the one communication terminal 1 on the touch panel surface of the one communication terminal 1. . Hereinafter, an operation of rubbing at a predetermined speed or more on the surface of the touch panel may be referred to as “flick”. The communication terminal 1 generates transmission destination direction information and distance information based on a flick from the user, and transmits the information to the server 2. The transmission destination direction information here is information for specifying the direction from the one communication terminal 1 to which the flick is performed toward the data transmission destination in the above-described map. The distance information is information that specifies the distance from the communication terminal 1 on the data transmission side to the data transmission destination in the above-described map. Hereinafter, the distance from the communication terminal 1 on the data transmission side to the communication terminal 1 on the data reception side in the map may be referred to as “transmission destination distance”.

Determine whether or not. The server 2 transmits information corresponding to the determination result to the communication terminal 1 that has transmitted the transmission destination direction information and the distance information.

  Next, each configuration of the radio communication system according to the present embodiment will be described. FIG. 2 is a block diagram showing the configuration of the communication terminal 1. As shown in FIG. 2, the communication terminal 1 includes a GPS (Global Positioning System) receiver 11, an electronic compass 12, a touch panel 13, a detection information processing unit 14, a storage device 15, a communication processing unit 16, And a control unit 17.

  The GPS receiver 11 serving as a position acquisition unit determines whether the GPS satellite and the terminal are based on the difference between the time when the signal is transmitted from the GPS satellite and the time when the signal is received by the GPS receiver 11. Measure distance. The GPS receiver 11 acquires position information that specifies the position of the terminal in terms of latitude and longitude by measuring distances between a plurality of GPS satellites having different positions. Then, the GPS receiver 11 outputs the acquired position information to the control unit 17.

  The electronic compass 12 includes two magnetic sensors that detect weak geomagnetism and a three-axis acceleration sensor. Each of the two magnetic sensors included in the electronic compass 12 detects the magnitude of geomagnetism on the detection axis as a vector. The detection axes of the two magnetic sensors are arranged orthogonal to each other. The electronic compass 12 can detect the direction of geomagnetism by combining the vectors detected by the two magnetic sensors. Thereby, the electronic compass 12 detects which is the north direction.

  The triaxial acceleration sensor included in the electronic compass 12 detects the direction of the terminal axis predetermined for the communication terminal 1. In the present embodiment, the outer shape of the communication terminal 1 is a substantially rectangular parallelepiped extending in one direction, and the terminal axis is defined along the longitudinal direction of the communication terminal 1. For example, when the vector representing the direction of the terminal axis when the z-axis direction is the vertical direction is (X, Y, Z) in the xyz coordinate space, the triaxial acceleration sensor is vector (X, Y, 0). ) Is detected as the own terminal direction. That is, the three-axis acceleration sensor of the electronic compass 12 detects the horizontal component of the vector representing the direction of the terminal axis as the direction of the own terminal. The electronic compass 12 acquires azimuth information specifying the azimuth of the own terminal direction based on the north direction detected by the two magnetic sensors and the own terminal direction detected by the three-axis acceleration sensor. The electronic compass 12 outputs the own terminal direction to the angle acquisition unit 31 and outputs the direction information of the own terminal direction to the control unit 17.

  The touch panel 13 as an operation unit includes a display unit 21 and a detection unit 22. The display unit 21 displays an image by being controlled by the control unit 17 via the detection information processing unit 14. Icons for identifying each of the plurality of data files may be displayed on the display unit 21. Hereinafter, the surface of the display unit 21 and the surface of the touch panel 13 are used in the same meaning without being distinguished from each other.

  The detection unit 22 detects various operations from the user on the surface of the display unit 21. The user presses the surface of the display unit 21 in order to select an icon displayed on the display unit 21. The detection unit 22 detects the press. In addition, the user of one communication terminal 1 specifies the data transmission destination on the surface of the display unit 21 in order to specify the direction of the data transmission destination among the plurality of communication terminals 1 excluding the one communication terminal 1. Flick toward. The detection unit 22 detects the flick direction and the speed of the flick. In addition, the user drags an icon displayed on the display unit 21 on the surface of the display unit 21 in order to move the icon in the display unit 21. Dragging here refers to an operation of rubbing the surface of the display unit 21 at a speed slower than the speed of rubbing with a flick.

  The detection information processing unit 14 processes information according to the operation detected by the touch panel 13. The detection information processing unit 14 determines whether the flick speed detected by the detection unit 22 is equal to or higher than a predetermined speed. When the detection information processing unit 14 determines that the speed detected by the detection unit 22 is slower than the predetermined speed, the detection information processing unit 14 determines that a drag is performed on the display unit 21. On the other hand, when the detected information processing unit 14 determines that the speed detected by the detecting unit 22 is equal to or higher than the predetermined speed, the detected information processing unit 14 determines that the display unit 21 has flicked.

  The detection information processing unit 14 includes an angle acquisition unit 31 and a distance acquisition unit 32. The angle acquisition unit 31 receives the terminal direction detected by the electronic compass 12 and the flick direction detected by the detection unit 22. The angle acquisition unit 31 acquires angle information for specifying an angle formed by the flick direction detected by the detection unit 22 with respect to the own terminal direction detected by the electronic compass 12. The angle acquisition unit 31 outputs the acquired angle information to the control unit 17.

  As described above, the azimuth information acquired by the electronic compass 12 specifies the azimuth in the own terminal direction. On the other hand, the angle information acquired by the angle acquisition unit 31 specifies an angle formed by the flick direction with respect to the own terminal direction. Therefore, the direction of the flick direction, that is, the direction of the data transmission destination in the latitude and longitude is specified from the direction information and the angle information. The server 2 to be described later generates a map that specifies the positional relationship of the plurality of communication terminals 1 using latitude and longitude as coordinates. Therefore, the transmission destination direction information composed of the azimuth information and the angle information specifies the direction of the data transmission destination in the map generated by the server 2. In this way, the transmission destination direction information generation unit 18 including the electronic compass 12 that acquires the azimuth information and the angle acquisition unit 31 that acquires the angle information displays the transmission direction information that specifies the direction of the data transmission destination in the map. Generate.

  The distance acquisition unit 32, which is a distance information generation unit, has a table in which the flicking speed and the distance information are associated one to one. In this table, as the flick speed increases, the flick speed is associated with the distance information so that the transmission destination distance specified by the distance information increases. The distance acquisition unit 32 determines a transmission destination distance corresponding to the flick speed detected by the detection unit 22 from the conversion table, and generates and acquires distance information for specifying the determined transmission destination distance. The distance acquisition unit 32 outputs the acquired distance information to the control unit 17.

  The storage device 15 stores various information. The storage device 15 stores unique information that identifies the terminal itself, and preferably stores the telephone number of the other communication terminal 1 and the user's information (for example, the user's name).

  The communication processing units 16 of the plurality of communication terminals 1 and the server 2 transmit and receive signals to and from each other via the base station 3. The communication processing unit 16 corresponds to a communication device compliant with, for example, CDMA, WCDMA, WiMAX, or WiFi (registered trademark). The communication processing unit 16 includes a transmission unit 41 and a reception unit 42. Here, the transmission unit 41 will be described, and the reception unit 42 will be described later. The transmission unit 41 modulates the carrier wave based on the information output from the control unit 17. A signal transmitted from the transmission unit 41 of one communication terminal 1 is transmitted to the server 2 or the one communication terminal 1 to another communication terminal 1 via the base station 3. Thereby, the transmission unit 41 of one communication terminal 1 transmits information to the server 2 or a plurality of communication terminals 1 excluding the one communication terminal 1. The transmission unit 41 of the communication terminal 1 transmits unique information, position information, orientation information, angle information, and distance information to the server 2. The transmission unit 41 of one communication terminal 1 transmits data to any one of the plurality of communication terminals 1 excluding the one communication terminal 1.

  The control unit 17 controls the GPS receiver 11, the electronic compass 12, the detection information processing unit 14, the storage device 15, and the communication processing unit 16. Further, the control unit 17 controls the touch panel 13 via the detection information processing unit 14.

  FIG. 3 is a block diagram showing the configuration of the server 2. As illustrated in FIG. 3, the server 2 includes a communication unit 51, a map generation unit 52, and a determination unit 53. The communication unit 51 of the server 2 performs wireless communication with the plurality of communication terminals 1. Based on the position information transmitted from each of the plurality of communication terminals 1, the map generation unit 52 generates a map that specifies the positional relationship between the plurality of communication terminals 1 in the latitude / longitude coordinate system.

  The determination unit 53 maps the direction of the data transmission destination based on the transmission destination direction information including the azimuth information and the angle information transmitted from the one communication terminal 1 and the map generated by the map generation unit 52. Specified in Further, the determination unit 53 specifies the distance information from the one communication terminal 1 in the map based on the distance information transmitted from the one communication terminal 1 and the map generated by the map generation unit 52. A transmission destination separated by a transmission destination distance is specified. In the present embodiment, the transmission destination specified by the distance information is, for example, a range of several meters before and after a point away from the one communication terminal 1 by the transmission destination distance specified by the distance information. The determination unit 53 is located in the direction of the transmission destination specified by the transmission destination direction information among the plurality of communication terminals 1 excluding the one communication terminal 1 on the data transmission side in the map, and is specified by the distance information. It is determined whether or not there is a communication terminal 1 located at a transmission destination separated from the one communication terminal 1 by a transmission destination distance.

  When the determination unit 53 determines that there is a communication terminal 1 located in a transmission destination that is located in the direction of the transmission destination specified by the transmission destination direction information and separated by the transmission destination distance specified by the distance information. The communication unit 51 of the server 2 wirelessly transmits unique information specifying the communication terminal 1 to the one communication terminal 1 that has transmitted the transmission destination direction information. In the determination unit 53, it is determined that there is no communication terminal 1 located in a transmission destination that is located in the direction of the transmission destination specified by the transmission destination direction information and that is separated by the transmission destination distance specified by the distance information. Then, the communication unit 51 of the server 2 wirelessly transmits to the one communication terminal 1 that transmitted the transmission destination direction information that there is no transmission destination terminal.

  The receiving unit 42 included in the communication terminal 1 illustrated in FIG. 2 demodulates the signal received from the server 2 and acquires information included in the signal. Similarly, the receiving unit 42 included in one communication terminal 1 demodulates a signal received from another communication terminal 1 and acquires information included in the signal. Thereby, the receiving unit 42 of one communication terminal 1 receives the information from the server 2 and the information from the other communication terminal 1. When the control unit 17 of the communication terminal 1 determines that the above-described specific information has been received by the reception unit 42, the control unit 17 transmits the data only to the communication terminal 1 specified by the specific information. 41 is controlled. Here, the data transmitted to the communication terminal 1 is a data file specified by an icon selected by the user pressing the display unit 21.

Each of the transmission source terminal 4 and the plurality of other communication terminals 5 a to 5 c transmits the position information and the unique information to the server 2 via the base station 3. In addition, the transmission source terminal 4 and the three other communication terminals 5 a to 5 c communicate with each other via the base station 3.

  Thereafter, the server 2 receives the position information and unique information transmitted from each of the transmission source terminal 4 and the plurality of other communication terminals 5 in the communication unit 51, and manages the received position information and unique information (FIG. 6). "Step S41"). Next, the map generation unit 52 of the server 2 generates a map based on the position information transmitted from each of the transmission source terminal 4 and the plurality of other communication terminals 5 (“step S42” in FIG. 6).

After step S3, the detection information processing unit 14 determines whether or not a flick on the surface of the display unit 21 has been detected by the detection unit 22 (“step S4” in FIG. 4). In step S4, when the detection information processing unit 14 determines that no flick has been made on the surface of the display unit 21, the process returns to step S1 to perform the process. On the other hand, when the detection information processing unit 14 determines in step S4 that the flick has been made on the surface of the display unit 21, the electronic compass 12 acquires orientation information, the angle acquisition unit 31 acquires angle information, and a distance. The acquisition unit 32 acquires distance information. Then, the control unit 17 causes the server 2 to transmit the azimuth information, the angle information, and the distance information (“Step S5” in FIG. 4).

First, the electronic compass 12 of the transmission source terminal 4 detects the own terminal direction B of the transmission source terminal 4 as shown in FIG. Then, the electronic compass 12 acquires azimuth information specifying the azimuth of the own terminal direction B based on the angle formed by the north direction A and the own terminal direction B. The electronic compass 12 outputs the detected own terminal direction B to the angle acquisition unit 31, and outputs direction information of the own terminal direction B to the control unit 17.

  The user performs flicking toward the data transmission destination direction on the surface of the touch panel 13 of the transmission source terminal 4 as an operation for designating the data transmission destination direction among the plurality of other communication terminals 5. Touch panel 13 receives the operation.

  FIG. 11 is a diagram illustrating a flick performed by the user when the user intends to transmit data to the other communication terminal 5c. As shown in the figure, when the user intends to transmit data to the other communication terminal 5c, a flick is performed in the direction C of the other communication terminal 5c. Thereby, the touch panel 13 receives the flick direction C. The angle acquisition unit 31 acquires angle information for specifying an angle formed by the flick direction C received by the touch panel 13 with respect to the own terminal direction B detected by the electronic compass 12. Then, the angle acquisition unit 31 outputs angle information to the control unit 17.

  The distance acquisition unit 32 acquires distance information for specifying the transmission destination distance according to the flick speed received by the touch panel. Then, the distance acquisition unit 32 outputs the distance information to the control unit 17. Then, the control unit 17 transmits the azimuth information acquired by the electronic compass 12, the angle information acquired by the angle acquisition unit 31, and the distance information acquired by the distance acquisition unit 32 to the server 2. 41 is transmitted.

  FIG. 12 is a diagram showing a display screen displayed on the display unit 21 of the touch panel 13 in step S2. As illustrated in FIG. 12, a plurality of icons 61 a to 61 i that respectively specify a plurality of data files are displayed on the display screen of the display unit 21. Here, as shown in FIG. 12A, when the icon 61c is flicked in the arrow direction D, there is almost no distance between the edge of the display screen and the icon 61c. It becomes difficult to perform a flick.

  Therefore, when the detection unit 22 detects a press on the icon 61c displayed on the end side of the display screen of the display unit 21 in step S2, as shown in FIG. Only the icon 61c in the center of the display screen may be displayed on the display unit 21. The same applies to the case where any one of the icons 61a, 61b, 61d, 61f to 61i is pressed. Thereby, even if the icon 61 is displayed on the end side of the display screen of the display unit 21, it can be easily flicked.

First, as illustrated in FIG. 13, the determination unit 53 identifies the own terminal direction B of the transmission source terminal 4 in the map based on the direction information. And as shown in FIG. 14, the determination part 53 specifies the flick direction C on the basis of the specified own terminal direction B. As shown in FIG. Thus, the flick direction C, which is the direction of the transmission destination on the map, is specified by the transmission destination direction information including the azimuth information and the angle information. Then, as illustrated in FIG. 15, the determination unit 53 specifies the transmission destination E that is separated from the transmission source terminal 4 by the transmission destination distance d based on the distance information in the direction along the specified flick direction C.

  Then, whether or not the determination unit 53 is located in the flick direction C specified by the transmission destination direction information and the other communication terminal 5 is located at the transmission destination E separated by the transmission destination distance specified by the distance information. Determine whether or not. In the example of FIG. 15, there is another communication terminal 5c located in the transmission destination E that is located in the flick direction C specified by the transmission destination direction information and that is separated by the transmission destination distance specified by the distance information. The determination unit 53 determines that the other communication terminal 5 exists.

  In the determination unit 53, it is determined that there is no other communication terminal 5 that is located in the transmission destination direction specified by the transmission destination direction information and that is located at the transmission destination that is separated by the transmission destination distance specified by the distance information. In such a case, the communication unit 51 of the server 2 wirelessly transmits to the transmission source terminal 4 that there is no transmission destination terminal (“step S45” in FIG. 6). Thereafter, the server 2 ends the current process. On the other hand, the determination unit 53 determines that there is another communication terminal 5 that is located in the transmission destination direction specified by the transmission destination direction information and that is located at a transmission destination that is separated by the transmission destination distance specified by the distance information. If it is, the communication unit 51 of the server 2 wirelessly transmits the unique information specifying the other communication terminal 5 to the transmission source terminal 4 (“step S46” in FIG. 6).

And if it determines with the other communication terminal 5 located in the transmission destination located in the direction of the above-mentioned transmission destination, the specific information which identifies the said other communication terminal 5 will be the above-mentioned one communication apparatus. Sent to. As a result, even if there are two or more other communication terminals 5 in the direction specified by the transmission destination direction information, data can be transmitted only to one other communication terminal 5.

  Further, according to the wireless communication system as described above, when a user performs a flick on the surface of the touch panel 13 of the transmission source terminal 4 toward the data transmission destination of the plurality of other communication terminals 5, the transmission is performed. The destination direction information generation unit 18 generates destination direction information based on the flick. Thereby, the user can select the other communication terminal 5 as a data transmission destination by a sensory operation called flick.

  Further, according to the wireless system as described above, when the server 2 determines that there is no other communication terminal 5 located in the direction of the transmission destination specified by the transmission destination direction information, there is no transmission destination terminal. The fact is wirelessly transmitted to the transmission source terminal 4. Then, the transmission source terminal 4 displays on the display unit 21 that there is no transmission destination terminal. Thereby, it is possible to prompt the user of the transmission source terminal 4 to perform the flick again.
