  FIG. 1 is an overall configuration diagram and a functional block diagram of a wristband 1 according to an embodiment of the present invention. As shown in the figure, this system includes a wristband 1 and a communication terminal 3 connected via a wireless LAN 2.

  The wristband 1 determines that the wristband wearer has intentionally performed the designated operation by detecting the designated operation subsequent to the detection of the notice operation. The wristband 1 instructs the communication terminal 3 to execute a process corresponding to the designated operation (hereinafter referred to as a specific process execution command) (for example, a mail application activation instruction).

  In the present embodiment, the wristband 1 transmits a specific process execution command to the communication terminal 3 when detecting the designated operation, but the present application is not limited to this. For example, when a designated operation is detected, the wristband 1 may execute a predetermined process corresponding to the designated operation detected in its own wristband, or only store it in a memory in the wristband.

  The communication terminal 3 has a communication function with the wristband 1, and when a specific process execution command is received from the wristband 1, executes a process corresponding to the command (for example, displays on the screen of the own communication terminal 3) Such). Further, the communication terminal 3 is a smartphone, and is equipped with a function (application or program) that activates the mail or telephone application installed in the communication terminal 3, and activates the function according to an instruction from the wristband. May be.

  The wristband 1 includes an acceleration sensor 101, an angular velocity sensor 102, a measurement value recording unit 103, a state detection unit 104, a notice action storage unit 105, a designated action storage unit 106, an action timing storage unit 107, a specific The processing execution unit 108 and the notification signal output unit 109 are configured.

  The acceleration sensor 101 measures the acceleration generated in accordance with the change in the moving speed of the wristband 1 and passes the acceleration measurement value to the measurement value recording unit 103 at a predetermined interval.

  The angular velocity sensor 102 measures the angular velocity generated with the change in the movement angle of the wristband 1 and passes the measured value of the angular velocity to the measured value recording unit 103 at a predetermined interval.

  The measurement value storage unit 103 stores the acceleration and angular velocity measurement values from the acceleration sensor 101 and the angular velocity sensor 102 together with the time passed. Furthermore, the measurement value recording unit 103 monitors changes in the stored measurement values of acceleration and angular velocity, and when changes in the measurement values of acceleration and angular velocity are detected, from the time when the detection is started until the time when the change is no longer detected. The measurement value is passed to the state detection unit 104 as an operation value.

  FIG. 2 is a diagram schematically showing a recording list 1030 recorded by the measurement value recording unit 103. As shown in the figure, the recording list 1030 includes a time field 1031 that records the measured time, an acceleration field 1032 that records acceleration, and an angular velocity field 1033 that records angular velocity, and records 1034 are recorded. The time field 1031 records the time in hours, minutes, seconds, and milliseconds. The acceleration field 1032 represents the X axis, Y axis, and Z axis detected by the acceleration sensor 101 as numerical values. The angular velocity field 1033 represents the angle per time detected by the angular velocity sensor 102 as a numerical value.

To do. The recording list recorded by the measured value recording unit 103 is overwritten at a fixed time. Returning to the description of FIG.

  The state detection unit 104 refers to the advance action storage unit 105 to determine whether the operation value is a advance action. If it is determined that the action is a notice operation, the state detection unit 104 waits for a new operation value to be passed from the measurement value recording unit 103. When a new motion value is passed from the measurement value recording unit 103, the state detection unit 104 refers to the designated motion storage unit 106 and determines whether or not the new motion value is a designated motion. If it is determined that the operation is the designated operation, the state detection unit 104 calculates the inter-operation timing from the time included in the new operation value and the time of the operation value passed in advance. If the inter-operation timing is within a predetermined range, the state detection unit 104 recognizes that a series of operations from the advance notice operation to the designated operation has been executed, and performs processing for specifying the information on the detected designated operation. The execution unit 108 is notified.

  The advance notice storage unit 105 is a storage unit that stores the advance action list 1050. In response to a request from the state detection unit 104, the notification operation storage unit 105 passes the acceleration values and the angular velocity motion values stored in the notification operation list 1050 to the state detection unit 104.

  FIG. 3 is a diagram schematically showing the notice action list 1050 stored in the notice action storage unit 105. As shown in the figure, the advance action list 1050 includes a advance action field 1051 for storing the advance action, an acceleration field 1052 for storing the acceleration of the advance action, and an angular velocity field 1053 for storing the angular speed of the advance action. A record 1054 is stored. The acceleration field 1052 represents the X-axis, the Y-axis, and the Z-axis indicating the advance notice operation by the acceleration sensor 101 as numerical values. The angular velocity field 1053 represents the angle per time when the angular velocity sensor 102 has detected the advance notice operation as a numerical value.

  The advance action list 1050 stored in the advance action storage unit 105 includes, for example, the acceleration stored in the acceleration field 1052 when the information stored in the advance action field 1051 is an action of moving the hand to the face position. The operation of moving the hand to the position of the face is stored in the plurality of records 1054 for the angular velocities stored in the angular velocity field 1053. In addition, the notice action list 1050 stores not only one action but also a plurality of notice actions. Returning to the description of FIG.

  The designated operation storage unit 106 is a storage unit that stores a designated operation list 1060. In response to a request from the state detection unit 104, the designated motion storage unit 106 passes the stored values of acceleration and angular velocity of the designated motion stored in the designated motion list 1060 to the state detection unit 104.

  FIG. 4 is a diagram schematically showing the designated action list 1060 stored in the designated action storage unit 106. As shown in the figure, the designated action list 1060 includes a designated action field 1061 for storing the designated action, an acceleration field 1062 for storing the acceleration of the designated action, and an angular velocity field 1063 for storing the angular speed of the designated action. A record 1064 is stored. The acceleration field 1062 represents numerical values on the X-axis, Y-axis, and Z-axis indicating the designated operation by the acceleration sensor 101. The angular velocity field 1063 represents the angle per time indicated by the angular velocity sensor 102 as a numerical value.

  The designated action list 1060 stored in the designated action storage unit 106 is stored in the acceleration field 1062 and the acceleration stored in the acceleration field 1062 and in the angular velocity field 1063, for example, in the case where the hand of the specified action field 1061 is shaken to the left and right. In the plurality of records 1064, the motion of shaking the hand from side to side is stored. The designated action list 1060 stores not only one action but also a plurality of notice actions.

  The operation timing storage unit 107 stores the time from detection of the advance notification operation to detection of the designated operation (hereinafter referred to as inter-operation timing), and notifies the inter-operation timing in response to a request from the state detection unit 104. .

  The notice operation, the designation operation, and the inter-operation timing will be described with reference to FIG. FIG. 5 is a diagram schematically showing a timing chart from detection of the advance notice operation to detection of the designated action. As shown in the figure, the notice operation timing chart 1071 shows a notice operation detection start timing 1072 and a notice operation detection end timing 1073. The designated operation timing chart 1074 shows a designated operation detection start timing 1075 and a designated operation detection end timing 1076. Furthermore, an inter-operation timing 1077 from a timing 1072 at which the start of the advance operation shown in the advance operation timing chart 1071 is detected to a timing 1075 at which the start of the designated operation shown in the designated operation timing chart 1074 is detected is shown.

  Specifically, when the operation value is passed from the measurement value recording unit 103, the state detection unit 104 stores the acceleration stored value and the angular velocity field 1053 in the acceleration field 1052 of the advance action list 1050 stored in the advance action storage unit 105. With reference to the stored value of the angular velocity stored in the step 1, it is determined whether or not the operation value is a warning operation. If it is determined that the action is a notice operation, the state detection unit 104 waits for a new operation value to be passed from the measurement value recording unit 103. When the measured values of the new motion acceleration and angular velocity are passed from the measured value recording unit 103, the state detecting unit 104 stores the acceleration stored value in the acceleration field 1062 of the designated motion list 1060 stored in the designated motion storage unit 106. Referring to the stored angular velocity value stored in the angular velocity field 1063, it is determined whether or not the new motion value is a designated motion. If it is determined that the operation is a designated operation, the state detection unit 104 calculates the inter-operation timing from the time included in the new operation value and the time included in the operation value passed in advance. Then, the state detection unit 104 determines whether or not the calculated inter-operation timing time is within the inter-operation timing time range stored in the operation timing storage unit 107. If it is within the range, the state detection unit 104 determines that the designated operation has been detected, and notifies the specific process execution unit 108 of information on the detected designated operation.

  When the specific process execution unit 108 is notified of the information on the designated operation detected from the state detection unit 104, the specific process execution unit 108 passes a specific process execution command corresponding to the information on the designated operation to the notification signal output unit 109.

  FIG. 6 is a diagram schematically showing the specific process execution list 1080 stored in the specific process execution unit 108. As shown in the figure, the specific process execution list 1080 includes a designated operation field 1081 and a specific process command field 1082, and stores a record 1083. When the information on the designated operation detected from the state detection unit 104 is passed, the specific process execution unit 108 refers to the designated operation field 1081 stored in the specific process execution list 1080 and corresponds to the specific process command field 1082 corresponding thereto. The specific process execution command is passed to the notification signal output unit 109. Here, the specific process execution command to be described is, for example, a command provided in the communication terminal 3 such as a mail application or an Internet search application.

  The notification signal output unit 109 outputs the specific process execution command passed from the specific process execution unit 108 to the communication terminal 3 connected to the wireless LAN 2.

  Next, a specific operation of the state detection unit 104 of the wristband 1 will be described with reference to FIG.

  FIG. 7 is a flowchart for explaining the processing operation of the wristband 1. This flow is started when the wristband 1 wearer moves his / her arm.

  When the wristband 1 detects the acceleration and angular velocity associated with the movement of the arm moved by the wearer (S11), the wristband 1 temporarily records the measured values of the acceleration and angular velocity together with the current time (S12). Next, the wristband 1 refers to the measurement value list 1030 in which the measurement values of acceleration and angular velocity are temporarily recorded and the warning action list 1050, and detects the warning action (S13). If no warning operation is detected (No in S14), wristband 1 returns to step 11.

  If the notification operation is detected (Yes in S14), the wristband 1 detects the designated operation with reference to the measurement value list 1030 in which the next measurement value is temporarily recorded and the designated operation list 1060 (S15). If the designated operation is not detected (No in S16), the wristband 1 returns to Step 11.

  If the designated operation is detected (Yes in S16), the wristband 1 calculates the inter-operation timing, compares the calculated inter-operation timing with the pre-stored inter-operation timing, and the calculated inter-operation timing is in the range. (S17). If the inter-operation timing is not within the range (No in S18), the wristband 1 returns to Step 11 and continues the processing. If the inter-operation timing is within the range (Yes in S18), the wristband 1 instructs the communication terminal 3 connected to the wireless LAN 2 to execute the specific process (S19). The instruction to execute the specific process is, for example, activation of a mail installed in the communication terminal 3 or activation of an information search function on the Internet.

  The embodiment of the present invention has been described above.

  In this embodiment, wristband 1 measures the acceleration and angular velocity of wristband, measures the change amount or change pattern of acceleration and / or angular velocity, and detects the designated operation following the detection of the reserved operation. Is detected, the communication terminal 3 connected via the wireless LAN 2 is notified of the execution of the specific action.

  Therefore, according to the present embodiment, the wristband 1 uses the predetermined motion shown in the present embodiment, for example, the motion of waving a hand that means negative to the left and right as a conscious designating operation. For example, it is possible to reduce false detection of unconscious movement by detecting an unconscious notice movement that moves the hand to the face position.

  The connection between the wristband 1 and the communication terminal 3 may be a wired LAN or a connection using short-range wireless.
