(Configuration of smart pad 1)
FIG. 4 is a block diagram showing a schematic configuration of the smart pad 1. In the figure, the smart pad 1 has a control unit 10, a storage unit 11, an input unit 12, an audio output unit 13, a display unit 14, a power supply unit 15, a power supply control unit 16, a WLAN communication unit 17 and a BT communication unit 18. is doing. The remaining units 10, 11, 12, 13, 14, 16, 17 and 18 except for the power supply unit 15 are connected by an internal bus 20.

  The control unit 10 controls each unit of the smart pad 1 and operates according to a control program stored in the storage unit 11. The storage unit 11 stores various data handled by the smart pad 1 in addition to storing a control program for operating the control unit 10. The input unit 12 is a touch panel, is arranged immediately above the display surface of the display unit 14, and outputs coordinates corresponding to a position touched by a user's finger as coordinate information. The coordinate information output from the input unit 12 is taken into the control unit 10. In addition, as a touch panel system, there are a resistive film system, a surface acoustic wave system, an electromagnetic induction system, a capacitive system, and the like. The smart pad 1 mainly employs a capacitive system. The capacitance method is a method of detecting a position by detecting a change in capacitance between a finger and a conductive film.

  The audio output unit 13 outputs audio and has a speaker (not shown). The audio output unit 13 generates an audio signal from the audio file and outputs it from the speaker when reproducing an audio file such as audio or music. The display unit 14 includes a liquid crystal display panel or an organic EL display panel, and displays information according to a display instruction from the control unit 10. The power supply unit 15 is a battery (including a rechargeable battery) and supplies power to each unit of the apparatus.

(Operation of smart pad 1)
FIG. 5 is a flowchart for explaining the operation of the smart pad 1. In the figure, the control unit 10 of the smart pad 1 first determines whether a pairing operation (initial registration) has been performed (step S1). When the user of the smart pad 1 tries to pair, the smart pad 1 and the smartphone are operated by simultaneously operating pairing operation buttons (both not shown) provided on each of the smart pad 1 and the smartphone 3. In each of 3, an inter-device cooperation start trigger is activated, and pairing processing is executed. During the inter-device cooperative operation, the WLAN communication unit 17 is used for data communication, and the BT communication unit 18 is used for control.

  When it is determined that the pairing operation has been performed (that is, when “YES” is determined in Step S1), the control unit 10 searches for the opposite device using the WLAN communication unit 17 (Step S2). Here, the opposite device is the smartphone 3, and the search is performed. The WLAN communication unit 17 of the smart pad 1 starts in the STA (Station) mode, transmits a search packet (Probe Request), and searches the network. The WLAN communication unit 38 of the smartphone 3 (see FIG. 6 described later) responds to the probe request of the smart pad 1 with a Probe Response packet, so that the WLAN communication unit 17 of the smart pad 1 responds to the WLAN communication unit 38 of the smartphone 3. Find the network that configures. This operation is defined by IEEE 802.11 and is a known technique.

  After searching for the opposite device, the control unit 10 registers connection information using the WLAN communication unit 17 and the BT communication unit 18 (step S3). In registration of connection information, (1) Bluetooth (registered trademark) BD (Bluetooth (registered trademark) Device) Address and security setting of the smartphone 3 are registered. (2) Register the SSID (Service Set Identifier) and security settings of the smartphone 3. The SSID is an identifier of a network that the WLAN communication unit 38 of the smartphone 3 starts and builds in the AP mode. By performing the processing from step S1 to step S3 (registration of connection information), the pairing of the smart pad 1 and the smartphone 3 is completed.

  After registering the connection information, the control unit 10 displays a counter device registered pict (or “paired pict”, see FIG. 2) 52a (step S4). After displaying the counter device registered pict 52a, a link with the counter device is established (step S5). In establishing the link, a connection request packet is transmitted to the smartphone 3, and a response indicating that the connection is possible is returned from the smartphone 3 in response to the connection request. As a result, a link with the opposite device is established. When the link is established, the control unit 10 displays the inter-device cooperative operation enabled state pict 52b (see FIG. 2) (step S7). On the other hand, when determining in step S1 that the pairing operation has not been performed, the control unit 10 searches for registered target devices (step S6), and then proceeds to the process of step S5.

  After performing the process of step S7, the control unit 10 determines whether the Bluetooth device connection state is disconnected from the connection (step S8). That is, it is determined whether or not the connection with the opposite device is disconnected. In this determination, if it is determined that the connection is disconnected (“YES” in the determination in step S8), the display of the inter-device cooperative operation enabled state pict 52b is stopped (step S9). Next, the counter device registered pict 52a is displayed (step S10). After performing the process of displaying the counter device registered pict 52a, the process returns to step S1.

  If it is determined in step S8 that the Bluetooth device connection state is not disconnected ("NO" in step S8), it is determined whether or not the WLAN device connection state connection is disconnected (step S11). In this determination, if it is a disconnection (in the case of “YES” in the determination in step S11), the display of the inter-device cooperative operation enabled state pict 52b is continued (step S12), and the process proceeds to step S13. On the other hand, if it is determined in step S11 that the connection state between the devices in the WLAN is not disconnected (NO in step S11), the process proceeds to step S13 without performing step S12. . If the process of step S12 is performed and the process proceeds to step S13 or the process proceeds to step S13 without performing the process of step S12, the inter-device cooperative operation is enabled (step S13), and the process returns to step S8.

  As described above, in the smart pad 1, after pairing with the smartphone 3 is completed and connection information is registered, the counter device registered pict 52a is displayed and a link with the smartphone 3 is established. The cooperative operation possible state pictograph 52b is displayed. Thereafter, if the connection state between the Bluetooth devices is disconnected, the display of the inter-device cooperative operation enabled state pict 52b is stopped, and the counter device registered pict 52a is displayed. On the other hand, if the inter-device connection state of the WLAN is disconnected, the inter-device cooperative operation enabled state picture 52b is continuously displayed.

The storage unit 31 stores various data handled by the smartphone 3 in addition to storing a control program for operating the control unit 30. The input unit 32 is a touch panel, is arranged immediately above the display surface of the display unit 34, and outputs coordinates corresponding to the position touched by the user's finger as coordinate information. The coordinate information output from the input unit 32 is taken into the control unit 30. As a touch panel system, there are a resistive film system, a surface acoustic wave system, an electromagnetic induction system, an electrostatic capacity system, and the like, and the smartphone 3 mainly employs an electrostatic capacity system. The capacitance method is a method of detecting a position by detecting a change in capacitance between a finger and a conductive film.

(Operation of smartphone 3)
FIG. 7 is a flowchart for explaining the operation of the smartphone 3. In the figure, the processing in the smartphone 3 is substantially the same as the processing in the smart pad 1 described above, and only different processing will be described. The processes in steps S2 and S3 of the smart pad 1 shown in FIG. 5 are steps S20 and S21 in the smartphone 3. In the smart pad 1, the opposite device is searched using the WLAN communication unit 17 in step S2. However, in the smartphone 3, the opposite device is searched using the BT communication unit 39 in step S20. Here, the opposing device is the smart pad 1, and the search is performed. The BT communication unit 39 of the smartphone 3 is activated in the master mode, transmits an inquiry packet, and searches for a counter device. When the BT communication unit 18 of the smart pad 1 returns an inquiry packet response to the inquiry packet from the smartphone 3, the BT communication unit 39 of the smartphone 3 can find the presence of the smart pad 1. This operation is defined by Bluetooth (registered trademark) and is a known technique.
The smart pad 1 may be activated in the master mode to search for the smartphone 3.

  In the smart pad 1, the connection information is registered using the WLAN communication unit 17 and the BT communication unit 18 in step S3. However, in the smartphone 3, the connection information is registered using the BT communication unit 39 in step S21. I do. In the registration of the connection information, the Bluetooth (registered trademark) BD (Bluetooth (registered trademark) Device) Address and the security setting of the smart pad 1 are registered. As described above, the processing is different from that of the smart pad 1.

  As described above, in the smartphone 3, after pairing with the smart pad 1 is completed and connection information is registered, the counter device registered pict 52a is displayed and a link with the smart pad 1 is established. An inter-cooperation possible state pict 52b is displayed. Thereafter, if the connection state between the Bluetooth devices is disconnected, the display of the inter-device cooperative operation enabled state pict 52b is stopped, and the counter device registered pict 52a is displayed. On the other hand, if the inter-device connection state of the WLAN is disconnected, the pictogram 52b display of the inter-device cooperative operation enabled state is continued.

  Thus, according to the smart pad 1 of this Embodiment, a pairing process is performed by the smart phone 3, WLAN, and Bluetooth, and a link establishment process is performed after completion of pairing. And after link establishment, the pictogram 52b which shows a cooperative operation possible state between the smart phones 3 is displayed on the display part 14. FIG. After that, when the connection with the smartphone 3 via Bluetooth is disconnected and the connection via WLAN is maintained, the display of the pictograph 52b is stopped, and the connection with the smartphone 3 via Bluetooth is maintained and the connection via WLAN is disconnected. If this happens, display of the pict 52b is continued. Accordingly, the cooperative operation possible state with the smartphone 3 is displayed as a pictograph on the display unit 14, so that the way of displaying the link state by wireless communication with the smartphone 3 becomes clear, and the user of the smart pad 1 If only one pictograph is seen, it can be very easily determined whether the cooperative operation with the smartphone 3 is valid or invalid.
