The sensor unit 31 having such a configuration delivers information detected by the proximity sensor 31a, the acceleration sensor 31c, the heart rate sensor 31d, and the angle sensor 31e to the information acquisition unit 32.

  The information acquisition unit 32 is triggered by the fact that the proximity sensor 21b of the portable terminal device 2 and the proximity sensor 31a of the external device 3 detect the proximity of the portable terminal device 2 and the external device 3. The information is continuously received from the two sensor units 21 and is continuously acquired from the sensor unit 31. Reception and acquisition of information by the information acquisition unit 32 is continuously performed at a predetermined cycle (for example, a 1-second cycle, a 10-second cycle, etc.). The information acquisition unit 32 stores the received and acquired information as sensor information in the sensor information storage unit 35.

  FIG. 4A shows an example of a data structure related to sensor information acquired from the sensor unit 31 and stored in the sensor information storage unit 35, and FIG. An example of the data structure regarding the sensor information stored in the information storage part 35 is shown. As shown in FIG. 4A, the sensor information acquired and accumulated from the sensor unit 31 includes an “external device ID” for identifying the external device 3 and a “detection” indicating the detection time of the acquired sensor information. The “time”, “angle information” detected by the angle sensor 31e, “heart rate information” detected by the heart rate sensor 31d, and “acceleration” detected by the acceleration sensor 31c are stored in association with each other. . “Angle information” and “acceleration” included in the sensor information are continuously acquired every second and stored in association with the corresponding detection time. “Heart rate information” included in the sensor information is: It is continuously acquired every 10 seconds and stored in association with the corresponding detection time. As shown in FIG. 4B, the sensor information received and accumulated from the sensor unit 21 indicates the “terminal device ID” for identifying the portable terminal device 2 and the detection time of the acquired sensor information. “Detection time”, “angle information” detected by the angle sensor 21e, “heart rate information” detected by the heart rate sensor 21d, “approach” indicating the presence or absence of approach detected by the proximity sensor 21b, and illuminance The “illuminance” detected by the sensor 21a and the “acceleration” detected by the acceleration sensor 21c are stored in association with each other. “Angle information”, “approach”, “illuminance”, and “acceleration” included in the sensor information are continuously received every second and stored in association with the corresponding detection time. The included “heart rate information” is continuously received every 10 seconds and stored in association with the corresponding detection time.

  Returning to FIG. 1, the information reference unit 33 refers to the sensor information whose detection time belongs to the predetermined period from the sensor information storage unit 35, and delivers the referred sensor information to the determination unit 34. In other words, the information reference unit 33 refers to sensor information about the external device 3 including the detection time close to the current time for a predetermined record (for example, 10 records including sensor information for 10 seconds) and passes it to the determination unit 34, The sensor information related to the portable terminal device 2 including the detection time close to the time is referred to a predetermined code and delivered to the determination unit 34.

  The determination unit 34 determines whether the sensor information satisfies a predetermined unlock condition based on the sensor information regarding the external device 3 and the portable terminal device 2 delivered from the information reference unit 33. Here, the determination unit 34 determines the unlock condition for a plurality of records having consecutive sensor information of the latest detection time, and determines whether or not the unlock condition is satisfied by the plurality of records. For example, for sensor information other than heart rate information accumulated for each record, it is determined whether the unlocking condition is satisfied continuously for 3 records, and for heart rate information accumulated at intervals of 10 records, It is determined whether any of the 10 records satisfies the unlock condition. As a result, when it is determined that the unlock condition is satisfied, the determination unit 34 transmits an unlock signal to the portable terminal device 2 via the short-range communication module 306 (see FIG. 3). To do.

  Here, the determination unit 34 determines the unlocking condition as follows. First, the determination unit 34 calculates an angle difference between the portable terminal device 2 and the external device 3 based on the angle information of the portable terminal device 2 and the angle information of the external device 3, and the angle difference is within a specified range ( For example, it is determined whether or not the angle is within a predetermined value γ degrees (angle difference condition). Further, the determination unit 34 further determines whether or not the portable terminal device 2 is approaching the external device 3 based on the approach information of the portable terminal device 2 (approach condition). Further, the determination unit 34 determines whether both accelerations are within a specified range (for example, less than a predetermined value δ) based on the acceleration information of the portable terminal device 2 and the acceleration information of the external device 3 (acceleration condition). ) Is also determined. In addition, the determination unit 34 also determines whether or not the illuminance is within a specified range (for example, a predetermined value α or more) based on the illuminance information of the portable terminal device 2 (illuminance condition). Further, the determination unit 34 calculates an error (heart rate difference) that is a difference between both heart rate information based on the heart rate information of the portable terminal device 2 and the heart rate information of the external device 3. It is further determined whether or not the error is within a specified range (for example, a predetermined value ω or less) (heart rate condition). Note that the determination unit 34 determines whether all the latest three records of the sensor information satisfy the condition regarding the angle difference condition, the approach condition, the acceleration condition, and the illuminance condition other than the heart rate condition, and the heart rate condition With respect to, it is determined whether any of the latest 10 records satisfies the condition. And the determination part 34 determines with satisfy | filling unlock conditions, when all the conditions are satisfy | filled.

  For example, in the example of the sensor information shown in FIG. 4, when it is determined that two consecutive records having the detection times “hh: mm: 01” and “hh: mm: 02” are targeted, the acceleration related to the external device 3 Since “A2” does not satisfy the acceleration condition (less than the predetermined value δ), it is determined that the unlock condition is not satisfied. In addition, when it is determined that three consecutive records with detection times “hh: mm: 03” to “hh: mm: 05” are targeted, angle information “β” regarding the external device 3 and angle regarding the portable terminal device 2 Since the information “α” does not satisfy the angle difference condition (within a predetermined value γ degrees), it is determined that the unlock condition is not satisfied. Also, the detection times “hh: mm: 06”, “hh: mm: When it is determined that two consecutive records of “07” are targeted, the acceleration “A3” related to the portable terminal device 2 does not satisfy the acceleration condition (less than the predetermined value δ), and therefore it is determined that the unlock condition is not satisfied. In addition, when it is determined that three consecutive records having the detection times “hh: mm: 08” to “hh: mm: 10” are targeted, the approach information regarding the portable terminal device 2 is “none”. It is determined that the unlocking condition is not satisfied because it does not satisfy the cage approach condition. If it is determined that three consecutive records from “hh: mm: 11” to “hh: mm: 13” are targeted, it is determined that the unlock condition is satisfied because all the conditions are satisfied. The

  Hereinafter, the procedure of the screen unlocking operation in the portable terminal device 2 and the external device 3 will be described, and the screen unlocking method according to the present embodiment will be described in detail. FIG. 5 is a flowchart showing an operation procedure for releasing the screen lock of the portable terminal device 2, and FIG. 6 is a flowchart showing an operation procedure for releasing the screen lock of the external device 3. Here, in the operations shown in FIGS. 5 and 6, the short-range wireless communication connection is established between the portable terminal device 2 and the external device, and the input / output control unit 23 of the portable terminal device 2 displays the screen. Start with the lock set. FIG. 7 is a diagram illustrating an example of a usage pattern of the information processing apparatus 1 at the time of a screen lock release operation by the user.

  First, referring to FIG. 5, a lock screen indicating a screen lock state is displayed on touch panel display 24 by input / output control unit 23 when a user performs a predetermined operation such as touching touch panel display 24. (Step S101). Then, the sensor unit 21 repeatedly determines whether or not the approach between the portable terminal device 2 and the external device 3 is detected (step S102). As a result, the portable terminal device 2 searches for the external device 3 that controls the unlocking process. If an approach is detected as a result of the determination (step S102; YES), the sensor unit 21 requests return information from the external device 3, and a process for receiving the return information is executed (step S103). . Next, it is determined by the sensor part 21 whether return information was received (step S104). If the return information is not received as a result of the determination (step S104: NO), the input / output control unit 23 notifies the user that the external device 3 has not been detected (FIG. 8). Is output on the touch panel display 24.

  On the other hand, if the return information is received as a result of the determination in step S104 (step S104; YES), the sensor unit 21 includes the illuminance sensor 21a, the proximity sensor 21b, the acceleration sensor 21c, the heart rate sensor 21d, and the angle sensor. Sensor information is detected using 21e (step S106). Then, the sensor unit 21 continuously transmits the detected sensor information to the external device 3 (step S107).

  Thereafter, the unlock control unit 22 determines whether an unlock signal is received from the external device 3 (step S108). If a lock release signal is received as a result of the determination (step S108; YES), the lock release control unit 22 and the input / output control unit 23 execute a screen lock release process (step S109). On the other hand, when the lock release signal has not been received (step S108; NO), the process returns to step S102, and the search for the external device 3 is repeated again.

  Moving to FIG. 6, in the external device 3, the sensor unit 31 repeatedly determines whether or not an approach signal for requesting return information is received from the portable terminal device 2 (step S <b> 201). As a result of the determination, if an approach signal is received (step S201; YES), the sensor unit 31 determines whether or not the portable terminal device 2 and the external device 3 are approaching using the proximity sensor 31a. (Step S202). As a result of the determination, if it is determined that there is no approach (step S202; NO), the process returns to step S201, and the determination of the reception of the approach signal is repeated again. On the other hand, when it is determined that there is an approach (step S202; YES), return information is transmitted from the sensor unit 31 toward the portable terminal device 2 (step S203).

  Next, sensor information is continuously detected by the sensor unit 31 using the acceleration sensor 31c, the heart rate sensor 31d, and the angle sensor 31e (step S204). And the information acquisition part 32 acquires sensor information from the sensor part 31, and accumulate | stores the acquired sensor information in the sensor information storage part 35 (step S205). Furthermore, the sensor information of the portable terminal device 2 is acquired by the information acquisition unit 32, and the acquired sensor information is stored in the sensor information storage unit 35 (step S206).

  Thereafter, the information reference unit 33 refers to the sensor information regarding the portable terminal device 2 and the external device 3 whose detection time belongs to the predetermined period from the sensor information storage unit 35, and the referred sensor information is delivered to the determination unit 34 ( Step S207). Next, the determination unit 34 determines whether the unlock condition is satisfied based on the sensor information delivered from the information reference unit 33 (step S208). As a result of the determination, when it is determined that the unlocking condition is not satisfied (step S208; NO), the determination unit 34 sends a message notifying that the screen unlocking process has failed, to the portable terminal device 2. Is sent to step S207 (step S209). In response to this, an output screen (see FIG. 9) including a predetermined error message is displayed on the touch panel display 24 of the portable terminal device 2. On the other hand, when it is determined that the unlock condition is satisfied (step S208; YES), the determination unit 34 transmits an unlock signal to the portable terminal device 2 (step S210).

  According to the information processing device 1 and the screen unlocking method using the information processing device 1 described above, the angle difference between the angle of the portable terminal device 2 and the angle of the external device 3 is calculated, and the angle difference is calculated as follows. Depending on whether or not it is within the specified range, the screen lock release in the portable terminal device 2 is executed. As a result, the screen lock is released according to the angle relationship between the portable terminal device 2 and the external device 3, and a smooth releasing operation is possible even if the portable terminal device 2 is enlarged. Furthermore, for example, by holding the portable terminal device 2 with one hand and attaching the external device 3 to the other hand, a smooth release operation can be performed even when the vehicle is being boarded. As a result, the screen unlocking operation can be smoothly performed regardless of the size of the apparatus and the operation environment of the user.

  In addition, since the screen lock is released according to the determination result of the relationship between the distance between the portable terminal device 2 and the external device 3, it is possible to prevent the screen lock release unintended by the user from being executed. Furthermore, since screen unlocking is executed according to the acceleration of the portable terminal device 2 and the acceleration of the external device 3, it is possible to further prevent the screen unlocking unintended by the user.

  In addition, since the screen lock is released when the ambient illuminance is within the specified range, for example, when the portable terminal device 2 or the external device 3 is stored in a bag or the like and is not used, unnecessary screen lock is performed. Execution of release can be prevented. Further, the screen unlock is executed according to the difference between the heart rate detected by the portable terminal device 2 and the heart rate detected by the external device 3, so that the same user can receive the portable terminal device 2 and the external device. Release operation is performed when 3 is close. As a result, it is possible to prevent malfunction of screen unlocking.

  In addition, this invention is not limited to embodiment mentioned above. For example, any combination of the angle difference condition, the approach condition, the acceleration condition, the illuminance condition, and the heart rate condition may be selected as the unlocking condition determined by the determining unit 34. However, in order to smoothly perform the unlocking operation of the screen lock, it is preferable that the unlock condition includes the minimum angle difference condition.

  In addition, both or one of the sensor information storage unit and the unlock condition determination unit may be included in the portable terminal device.
