Description

The present invention relates to wearable terminals and wearable terminal systems.

A wearable terminal, such as an electronic watch, has been proposed that can transmit and receive information to and from a terminal device owned by a user via wireless communication. Electronic timepieces have a timepiece display that allows users to recognize the current time. The clock display section is driven by power supplied from a battery mounted on the electronic clock.

The amount of charge in the battery is monitored by the control unit of the electronic timepiece, and when the amount of charge falls below the notification threshold value, charging warning information prompting the user to charge the electronic timepiece is notified. The notification of charging warning information may be performed by the electronic timepiece itself, but may also be performed by a terminal device (see Patent Document 1). When the charging warning information is notified by the terminal device, the charging warning information is displayed on the display unit when the charge amount received from the electronic timepiece is equal to or less than the notification threshold value.

WO2017/159761

By the way, the terminal device receives the amount of charge from the electronic timepiece each time it is connected to the electronic timepiece for communication. Therefore, when charging warning information is notified when the charge amount received from the electronic timepiece is equal to or less than the notification threshold value, the charging warning information is notified each time the communication connection is established. The user can recognize the need to charge the electronic timepiece by being notified of the charge warning information when the charge amount received from the electronic timepiece becomes equal to or less than the notification threshold value for the first time. Therefore, it may be troublesome for the user to notify the charge warning information by the terminal device each time the terminal device is connected for communication.

The terminal-side counting unit 35a counts the grace period X. FIG. Here, the grace period X is a period sufficient for the user after the charge amount CA becomes equal to or less than the notification threshold CAT during a non-grace period that is not within the grace period X. The grace period X in the present embodiment is set so that the possibility that the user can actually charge the electronic timepiece 2 when the charge warning information image P is viewed by the user at the end of the grace period X is set to be high. For example, the end of grace period X is set to be the second Saturday morning (9:00) from the start of grace period X. The terminal-side counting unit 35a starts counting the grace period X when the terminal-side control unit 35 determines that the charge amount CA is equal to or less than the notification threshold value CAT during the non-grace period. Note that the grace period X may be changed by the user operating the terminal device 3, for example, by operating the touch panel while the application is running. Further, the grace period X may be automatically changed according to the charge amount CA at the time when the charge amount CA becomes equal to or less than the notification threshold value CAT during the non-grace period.

For example, character string information based on the charging warning information image P may be output as a voice, or other warning sound may be output.

Next, notification of charging warning information by the wearable terminal system 1 according to the embodiment will be described. First, communication establishment processing between the electronic timepiece 2 and the terminal device 3 and charging information transmission processing in the electronic timepiece 2 will be described. FIG. 4 is a flowchart of charging information transmission processing in the wearable terminal. FIG. 5 is a flowchart of charge warning information notification processing in the terminal device.

First, the user makes a reconnection request to the terminal device 3, as shown in FIG. The user requests reconnection with the terminal device 3 by, for example, operating the operation unit 27 of the electronic timepiece 2 .

Next, the timepiece-side control section 23 of the electronic timepiece 2 determines whether or not a reconnection request with the terminal device 3 has been made (step ST201).

Next, when the watch-side control section 23 determines that a request for reconnection with the terminal device 3 has been issued (step ST201: Yes), it establishes communication with the terminal device 3 (step ST202). If the watch-side control section 23 determines that a reconnection request with the terminal device 3 has not been made (step ST201: No), step ST201 is repeated until a reconnection request with the terminal device 3 is made. .

Next, the watch-side control section 23 transmits the charge amount CA (step ST203). Here, when communication with the terminal device 3 is established, the watch-side control section 23 transmits the charging amount-related information stored in the watch-side storage section 28 to the terminal device 3 through the watch-side communication section 22 . The watch-side control unit 23 transmits charge amount related information to the terminal device 3 each time a communication connection with the terminal device 3 is established. When receiving the charge amount related information, the terminal device 3 stores the information in the terminal side storage unit 37 each time it receives the information, transmits the information to the external server 200 , and also stores the information in the external server 200 . The reason why the external server 200 also stores the charge amount related information is for backup when the terminal side storage unit 37 of the terminal device 3 loses the charge amount related information for some reason.

Next, charge warning information processing in the terminal device 3 will be described with reference to FIG. First, terminal-side control section 35 determines whether or not the grace period flag is ON (step ST301). Here, the terminal-side control unit 35 determines whether or not the grace period X is in effect.

Next, when the terminal-side control section 35 determines that the grace period flag is OFF (step ST301: No), the terminal-side control section 35 waits until the charge amount CA is acquired, that is, repeats step ST301.

After acquiring the charge amount CA (step ST302), the terminal-side control section 35 determines whether the charge amount CA is equal to or less than the notification threshold CAT (step ST303). Here, the terminal-side control unit 35 determines whether or not the charge amount CA has become equal to or less than the notification threshold value CAT during the non-grace period. If the terminal-side control section 35 determines that the charge amount CA is not equal to or less than the notification threshold value CAT (step ST303: No), the terminal-side control section 35 waits until the charge amount CA is obtained again, that is, repeats step ST302.

Next, when the terminal-side control section 35 determines that the charge amount CA is equal to or less than the notification threshold value CAT (step ST303: Yes), it causes the terminal-side notification section to notify charging warning information (step ST304). . Here, when the terminal-side control section 35 determines that the charge amount CA of the electronic timepiece 2 has become equal to or less than the notification threshold value CAT for the first time, the terminal-side control section 35 displays the charge warning information image P on the touch panel section 32 . Here, the terminal-side control unit 35 notifies the charging warning information again when the charging amount CA of the electronic timepiece 2 requires charging the electronic timepiece 2 during the non-grace period. As a result, the user can recognize the necessity of charging the electronic timepiece 2 without checking the position of the function hand 26f with respect to the charge amount display portion of the electronic timepiece 2, that is, the charge amount mark 26i.

Next, after turning on the grace period flag (step ST305), the terminal-side control section 35 causes the terminal-side counting section 35a to start counting (step ST306).

When the terminal-side control section 35 determines that the grace period flag is ON (step ST301: Yes), it determines whether or not the grace period X has ended (step ST307).

Next, when the terminal-side control section 35 determines that the grace period X has ended (step ST307: Yes), it determines whether or not there is a charge amount CA, that is, whether or not the charge amount CA was acquired during the grace period X. to decide. (Step ST308).

Further, when terminal-side control section 35 determines that grace period X has not ended (step ST307: No), terminal-side control section 35 acquires charge amount CA (step ST310). Here, the control-side terminal 35 repeatedly acquires the charge amount CA from the start to the end of the grace period X, and stores the charge amount CA in the terminal-side storage unit 37 after acquiring the charge amount CA.

Next, terminal-side control section 35 does not report charge warning information (step ST311). Here, the control-side terminal 35 does not display the charge warning information image P on the touch panel section 32 even if the charge amount CA acquired during the grace period X is equal to or less than the notification threshold value CAT.

In addition, when the terminal-side control unit 35 determines that there is a charge amount CA, that is, determines that the charge amount CA has been acquired during the grace period X (step ST308: Yes), the last acquired charge amount during the grace period X It is determined whether or not the immediately preceding charge amount CAR, which is CA, is equal to or less than the notification threshold value CAT. (Step ST309). Here, after the grace period X ends, the control-side terminal 35 determines whether or not the immediately preceding charge amount CAR, which is the charge amount CA immediately before the grace period X ends, is equal to or less than the notification threshold value CAT.

Next, when the terminal-side control section 35 determines that the immediately preceding charge amount CAR is equal to or less than the notification threshold value CAT (step ST309: Yes), it causes the terminal-side notification section to notify charging warning information. (Step ST304). Here, when the charge amount CA of the electronic timepiece 2 indicates that the electronic timepiece 2 needs to be charged at the end of the grace period X, the terminal-side control unit 35 notifies the charging warning information again. As a result, the user can recognize the necessity of charging the electronic timepiece 2 after a while without checking the position of the function hand 26f with respect to the charge amount display portion of the electronic timepiece 2, that is, the charge amount mark 26i. can.

Next, after causing the terminal-side notification unit to notify the charging warning information (step ST304), the terminal-side control unit 35 turns on the grace period flag again (step ST305), and sends the terminal-side counting unit 35a again. start counting. (Step ST306).

Further, when the terminal-side control section 35 determines that there is no charge amount CA during the grace period X, that is, the charge amount CA is not obtained during the grace period X (step ST308: No), the terminal-side control section 35 notifies charge warning information. First (step ST311), the process proceeds to step ST301 to determine whether or not the grace period flag, which is the start of the charging warning information processing in the terminal device 3, is ON. Here, since the charge amount CA during the grace period is unknown, charge warning information is not provided. As a result, compared to the case where the charge warning information is notified even if the charge amount CA of the electronic timepiece 2 at the end of the grace period X is unknown, the user does not recognize that the charge warning information is false. User annoyance can be suppressed.

Further, when the terminal-side control unit 35 determines that the immediately preceding charge amount CAR is not equal to or less than the notification threshold value CAT (step ST309: No), it does not notify charge warning information (step ST311), and the charge warning in the terminal device 3 The process proceeds to step ST301 for determining whether or not the grace period flag, which is the start of information processing, is ON. Here, the terminal-side control unit 35 does not notify the charge warning information when the charging amount CA of the electronic timepiece 2 does not require charging the electronic timepiece 2 at the end of the grace period.

As described above, the wearable terminal system 1 according to the present embodiment displays the charge warning information image P on the display surface 32a when the charge amount CA becomes equal to or less than the notification threshold CAT during the non-grace period. However, even if the charge amount CA becomes equal to or less than the notification threshold value CAT during the grace period X, the charging warning information image P is not displayed on the display surface 32a. In other words, charging warning information is not notified. Therefore, after the charge amount CA of the electronic timepiece 2 shifts from a high state to a low state and the user is made aware that the electronic timepiece 2 needs to be charged, the electronic timepiece 2 is charged during the grace period X. Even if the amount CA is low, the user is once notified that the electronic timepiece 2 needs to be charged, so that the user is notified that the electronic timepiece 2 needs to be charged again. Therefore, it is possible to suppress the user's annoyance regarding the notification of the charging warning information. The electronic timepiece 2 also has a function hand 26f and a charge level mark 26i as a charge indicator. Therefore, during the grace period X, the user can visually recognize the charge amount CA when viewing the electronic timepiece 2, so there is an opportunity for the user to recognize the charge amount CA of the electronic timepiece 2 during the grace period X. . As a result, during the grace period X, the need to charge the electronic timepiece 2 is not notified while the user recognizes the charge amount CA of the electronic timepiece 2 by visually recognizing the charging display unit. , it is possible to further suppress the user's annoyance regarding the notification of the charging warning information.

In the wearable terminal system 1 according to the present embodiment, the case where communication connection is possible between one electronic timepiece 2 and the terminal device 3 as a wearable terminal has been described, but the present invention is not limited to this, and a plurality of wearable terminals can be connected. and the terminal device 3 may be capable of communication connection. FIG. 6 is an overall configuration diagram of a wearable terminal system in a modified example.

The wearable terminal system 1 in the modified example includes a plurality of wearable terminals, here two electronic watches 2 and 2', and a terminal device 3, as shown in FIG. The wearable terminal system 1 transmits the charge amounts CA and CA' from the electronic watches 2 and 2' respectively to the terminal device 3, the terminal device 3 receives the charge amounts CA and CA', and the terminal device 3 receives the charge amounts CA and Based on CA', charge warning information is reported. Since the basic configuration and basic operation of the electronic timepiece 2' are the same as those of the electronic timepiece 2, the description thereof will be omitted.

When the terminal device 3 receives the charge amount-related information including the charge amount CA' from the electronic timepiece 2', the terminal device 3 stores the information in the terminal-side storage unit 37, transmits the information to the external server 200, and stores the information in the external server 200 as well.

Next, charging warning information processing in the terminal device 3 will be described. FIG. 7 is a flowchart of charging warning information notification processing in the terminal device. Of the charge warning information processing by the terminal device 3 in FIG. 5, the same portion as the charge warning information processing by the terminal device 3 in FIG. 5 is omitted or simplified.

Further, when terminal-side control section 35 determines that grace period X has not ended (step ST307: No), terminal-side control section 35 acquires charge amount CA (step ST310), and determines whether or not charge amount CA' has been acquired. is determined (step ST312). Here, the control-side control unit 35 determines whether or not the charging amount related information is transmitted from another electronic timepiece 2' different from the electronic timepiece 2 during the grace period X and the charging amount CA' is acquired as the terminal device 3. to judge.

Next, when the terminal-side control unit 35 determines that the charge amount CA' has been acquired (step ST312: Yes), it determines whether the charge amount CA' is equal to or less than the notification threshold value CAT ( step ST313). Here, the control-side control unit 35 determines whether or not the charge amount CA' of the electronic timepiece 2' different from the electronic timepiece 2 during the grace period X has become equal to or less than the notification threshold value CAT. When the terminal-side control unit 35 determines that the charge amount CA′ has not been obtained (step ST312: No), it does not notify the charge warning information (step ST311), and the charge warning information processing in the terminal device 3 The process proceeds to step ST301 to determine whether or not the grace period flag, which is the start, is ON.

Next, when the terminal-side control section 35 determines that the charge amount CA' is equal to or less than the notification threshold value CAT (step ST313: Yes), it causes the terminal-side notification section to notify charging warning information (step ST314). ). Here, when the terminal-side control section 35 determines that the charge amount CA' of the electronic timepiece 2' different from the electronic timepiece 2 has become equal to or less than the notification threshold value CAT for the first time during the grace period X, the touch panel section 32 A charging warning information image P is displayed. Here, the terminal-side control unit 35 notifies charge warning information when the charging amount CA' of another electronic timepiece 2' during the grace period of the electronic timepiece 2 requires charging of the electronic timepiece 2'. . As a result, even during the grace period X of the electronic timepiece 2, if there is a need to charge the other electronic timepiece 2', normally during the grace period X, the terminal-side notification unit will charge the electronic timepiece 2'. The user can recognize the necessity of charging the electronic timepiece 2', which is different from the electronic timepiece 2, by intentionally notifying the charge warning information by the terminal-side notification unit even though the warning information is not notified. When the terminal-side control unit 35 determines that the charge amount CA' exceeds the notification threshold value CAT (step ST313: No), it does not notify the charge warning information (step ST311), The process proceeds to step ST301 for determining whether or not the grace period flag, which is the start of information processing, is ON.

In the wearable terminal system 1 according to the modification, the charge amount CAM acquired during the grace period X may include the charge amount CA' included in the charge amount related information corresponding to the electronic timepiece 2'. In this case, the terminal-side control unit 35 causes the terminal-side notification unit to notify charging warning information when the immediately preceding charge amount CAMR corresponding to the electronic timepiece 2' is equal to or less than the notification threshold value CAT.

In addition, in the present embodiment and the modified example, whether or not to notify the charge warning information is determined using the charge amount related information stored in the terminal-side storage unit 37 of the terminal device 3, but the present invention is not limited to this. isn't it. For example, the terminal-side control unit 35 of the terminal device 3 receives the charge amount-related information stored in the external device 200 and determines whether or not to notify the charge warning information, that is, controls the charge warning. good.
