The control unit 110 provided in the portable terminal according to an embodiment of the present invention described above is particularly configured to perform an accessory loss warning method of an embodiment of the present invention. To this end, the control unit 110 provided in the present invention, as illustrated in FIG. 4, is provided with an accessory combination state checking unit 410, an accessory loss prediction unit 412, and a loss warning providing unit 413. do.
With the stylus pen 168 mounted on the portable terminal 100, the stylus pen 168 is in physical contact with the pen detachable recognition switch 169, and the stylus pen 168 is connected to the portable terminal 100. When it is withdrawn and detached from), physical contact with the pen detachment recognition switch 169 is released. In addition, the pen detachable recognition switch 169 may include a protrusion protruding into a space into which the stylus pen 168 is inserted, for physical contact with the stylus pen 168. The stylus pen 168 may be provided to be elastically formed into a space into which it is inserted. Through this configuration, in the state in which the stylus pen 168 is drawn out and detached, the protrusion is positioned as a space into which the stylus pen 168 is inserted, and the pen detachment recognition switch 169 is located at the position of the protrusion. Correspondingly, a signal indicating the detachment of the stylus pen 168 is generated and provided to the accessory coupling state check unit 410.
The accessory combination state checking unit 410 is connected to the pen detachment detecting switch 169 and receives a signal indicating the detachment or the mounting of the stylus pen 168, thereby preventing the loss of the accessory according to an embodiment of the present invention. Control start and end of operation. That is, when receiving a signal instructing the mounting of the stylus pen 168, and does not separately start the operation of issuing an accessory loss warning alarm, and maintains the standby state. On the other hand, the accessory combination state check unit 410 in response to receiving a signal indicating the removal of the stylus pen 168, initiating the operation of the accessory loss warning method, the accessory loss prediction unit 412 of the Instruct the operation.

Accordingly, the accessory combination state check unit 410 also, not a signal provided from the pen detachable recognition switch 169, the signal received from the magnetic sensor, a signal indicating whether or not to receive the antenna signal, the detachable attachment of the expansion connector In response to receiving an indication signal, a signal indicating a detachment of an earphone, a signal indicating whether to connect with a device supporting near field communication, and the like, the operation of the accessory loss prediction unit 412 may be instructed.
Meanwhile, the accessory loss prediction unit 412 estimates the distance between the stylus pen 168 and the portable terminal 100 to estimate the loss of the stylus pen 168.
The distance estimation between the stylus pen 168 and the portable terminal 100 is preferably confirmed using a motion sensor such as an acceleration sensor. In detail, the accessory loss prediction unit 412 activates a motion sensor included in the sensor module 170 and receives data on displacements of x, y, and z axes input from the motion sensor. The accessory loss prediction unit 412 tracks the user's movement displacement by using data on displacements of the x, y, and z axes. For example, the movement displacement of the user is tracked by checking how many steps the user has moved by reflecting a pattern of data on displacements of the x, y, and z axes as the user walks. This user's movement displacement tracking can be implemented using algorithms used in conventional pedometers (applications).
In addition, the accessory loss prediction unit 412 predicts that the stylus pen 168 may be lost when a predetermined threshold value is reached using the tracked displacement value of the tracked user, and thus a signal corresponding thereto. That is, the loss warning providing unit 413 transmits a signal indicating loss prediction.
As the loss warning providing unit 413 receives a signal indicating loss prediction from the accessory loss predicting unit 412, there is a possibility that the stylus pen 168 may be lost using a means that can be recognized by the user. Generate a warning alarm. The warning alarm is a warning sound generated by reproducing a predetermined sound source through the speaker 163, the vibration of the portable terminal 100 by the operation of the vibration motor 164 provided in the portable terminal 100, and the display controller 194 And a message pop-up with a predetermined content through the display 193. The warning alarm issuing method may be provided in various ways in consideration of a stylus pen lost alarm setting of a user or a profile set in a portable terminal.
In addition, the loss warning providing unit 413 may repeatedly issue the warning alarm for each predetermined moving distance unit. To this end, the loss warning providing unit 413 may issue the warning alarm, and then request the accessory loss prediction unit 412 to repeat the loss prediction operation. In addition, as an alternative thereto, the loss warning providing unit 413 does not request the accessory loss prediction unit 412 to repeat the loss prediction operation, and uses the counter provided therein to warn the warning alarm every predetermined time unit. Can be issued repeatedly.
The loss warning providing unit 413 may receive an alarm end from the user, end the operation of the loss warning providing unit 413, and request the accessory end prediction unit 412 to end the operation. For example, at least one of an input of a button 161 provided in the portable terminal 100, a keypad 166 provided in the portable terminal 100, or an input of a touch screen 191 is inputted. Issuance operation can be terminated. [0069] Although the configuration of the accessory warning providing device according to the preferred embodiment of the present invention has been illustrated, the present invention is not limited thereto. The above-mentioned accessory loss warning device can be variously changed and applied within the scope of realizing what the present invention intends to solve.
The accessory missing warning providing apparatus of the present invention may further include a terminal state checking unit 411 provided in the second CPU, and the accessory missing predicting unit 412 provides information provided by the terminal state checking unit 411. The reflection of the stylus pen 168 may be further reflected.
In detail, the terminal state checking unit 411 is connected to the accessory interface 197 and detects a signal generated from the accessory interface 197. The accessory interface 197 detects and uses a signal generated by the stylus pen 168, so when the accessory interface 197 detects a signal generated by the stylus pen 168, there is a relatively small possibility of loss. Therefore, it is necessary to initialize the warning alarm generation operation for loss. Accordingly, the terminal state checking unit 411 confirms the signal acquisition of the accessory interface 197 and generates an interrupt signal for initializing the warning alarm generation operation.
Also, similarly, the terminal state checking unit 411 reflects an operation state of the first CPU 111 that controls the main operation of the portable terminal 100, that is, an activation or deactivation state for initialization of the warning alarm generation operation. It will generate an interrupt signal. That is, the terminal state checking unit 411 generates an interrupt signal for initializing the warning alarm generation operation as the operation state of the first CPU 111 provided in the portable terminal 100 is switched to the active state.

6 is a flowchart illustrating an operation procedure of a lost accessory warning method according to an embodiment of the present invention.
First, the means for detecting the detachment of the accessory mounted on the portable terminal detects the detachment of the accessory mounted on the portable terminal, issues a signal instructing the detachment of the accessory, the accessory combination status check unit 410 ). Accordingly, the accessory combination state checking unit 410 receives a signal indicating the detachment of the accessory, and initiates the operation of the accessory loss warning method according to the present invention (S601). That is, the accessory coupling state check unit 410 instructs the operation of the accessory loss prediction unit 412.
On the other hand, when the user is to move the portable terminal 100 with the accessory is withdrawn from the portable terminal 100, that is, when the user carrying the portable terminal 100 is moved, the accessory Since the distance between the portable terminal 100 is far away, there is a fear that the accessory can be lost. Accordingly, the accessory loss prediction unit 412 estimates the distance between the accessory and the portable terminal 100 to proceed with the loss prediction operation of the accessory (S602).
The distance estimation between the accessory and the portable terminal 100 may be confirmed using a motion sensor such as an acceleration sensor. Specifically, the accessory loss prediction unit 412 is included in the sensor module 170. After receiving the data on the displacement of the x, y, z axis input from the motion sensor, using the data on the displacement of the x, y, z axis, it is possible to track the movement displacement of the user. For example, the movement displacement of the user is tracked by checking how many steps the user has moved by reflecting a pattern of data on displacements of the x, y, and z axes as the user walks.
And, the accessory loss prediction unit 412 predicts that the accessory can be lost when the tracked movement displacement tracking value of the tracked user reaches a predetermined threshold value, the loss warning providing unit indicating a signal To 413.
Meanwhile, as an alternative to estimating the distance between the accessory and the portable terminal 100 using the motion sensor by the accessory loss prediction unit 412, a module for confirming location information (eg, a GPS module 155). ), It is also possible to estimate the distance between the accessory and the portable terminal 100 using the WLAN module 131). In this case, the accessory loss prediction unit 412 requests and receives the location information to a module (for example, the GPS module 155, the wireless LAN module 131) to check the location information every predetermined time unit, After the accessory is detached, the first position information and the currently confirmed position information are used to confirm the displacement between the position of the accessory is detached and the current portable terminal 100. And, the accessory loss prediction unit 412 predicts that the accessory can be lost when the displacement value reaches a predetermined threshold value, the loss warning providing unit for a signal indicating the generation of a warning alarm for this Send to 413.
In addition, the accessory loss prediction unit 412 may predict the loss of the accessory by checking the time from when the accessory is detached, without performing an operation of estimating a distance. That is, even after a predetermined time has elapsed after the accessory is detached, when the accessory interface 197 or the first CPU 111 that controls the main operations of the portable terminal 100 does not proceed, In other words, the user is likely to move while carrying the bag, pocket, hand, etc. without using the portable terminal 100. Accordingly, the accessory loss prediction unit 412 does not perform the operation of estimating the distance, and if the time from the time when the accessory is detached exceeds a predetermined time, the accessory may be lost. In anticipation, the signal corresponding thereto may be transmitted to the loss warning provider 413.
Next, in step S603, as the loss warning providing unit 413 receives a signal indicating the prediction of the loss from the accessory loss prediction unit 412, means that can be recognized by the user (for example, the speaker 163, The vibration motor 164, the display controller 194, the display 193, etc. are activated to generate a warning alarm indicating that the accessory may be lost.
In addition, the loss warning providing unit 413 may be configured to repeatedly issue the warning alarm for every predetermined distance (S604). To this end, the loss warning providing unit 413 issues the warning alarm, requests the accessory loss prediction unit 412 to repeatedly perform the loss prediction operation, or uses a counter provided therein to provide a predetermined value. The warning alarm can be repeatedly issued every time unit. The repeated issuance of the warning alarm is terminated by receiving an alarm termination input from a user through input of a button 161, a keypad 166 provided in the portable terminal 100, or a touch screen 191. can do.
On the other hand, even if the accessory is detached from the portable terminal 100, if the user is used for the operation of the portable terminal, it is not necessary to proceed with the loss prediction operation of the accessory. Therefore, when the accessory is detached from the portable terminal 100 and is used for the operation of the portable terminal 100, an interrupt signal is issued to initialize the operation of the accessory loss warning method (S611). Such issuance of the interrupt signal may be issued at any of steps S602, S603, and S604, and is operated to initialize the operation of the accessory missing warning method without proceeding any further operation regardless of which step occurred. do.
For example, when the accessory interface 197 obtains a signal generated from the accessory, the accessory interface 197 acquires a signal from the accessory, and transmits information indicating this to the terminal status checker 411. to provide. When the terminal state checking unit 411 receives information indicating signal acquisition from the accessory, it is necessary to initialize a warning alarm operation for loss. 412). Then, the accessory loss prediction unit 412 initializes the process of performing the accessory loss prediction. For example, the accessory loss prediction unit 412 of the motion sensor (or the GPS module 155, or the wireless LAN module 131, etc.) to initiate the tracking process of the user's movement displacement. Initializes the operation, and re-initiates the operation of the motion sensor (or the GPS module 155, or the wireless LAN module 131, which operates to obtain location information).
Similarly, the first CPU 111 provided in the portable terminal 100 may provide information indicating an operation state (activation state) as the operation state of the portable terminal 100 is switched to the activation state. To provide. When the terminal state checking unit 411 receives information indicating an operation state (activation state) from the first CPU 111, the terminal state checking unit 411 needs to initialize a warning alarm operation for loss, and thus issues the first CPU activation interrupt. The accessory may be operated to be provided to the loss prediction unit 412 or the loss warning provider 413.
Figure 7 is a flow chart showing the operation sequence of the lost accessories warning method according to a preferred embodiment of the present invention.

The pen detachable recognition switch 169 provides a signal instructing the mounting of the stylus pen 168 while the stylus pen 168 maintains contact with the stylus pen 168, and the stylus pen 168 is drawn out and detached. As the projection moves to the space where the stylus pen 168 is inserted, the pen detachment recognition switch 169 issues a signal instructing the detachment of the stylus pen 168 and the accessory combination state checking unit 410. To provide. Accordingly, the accessory combination state check unit 410, in response to receiving a signal indicating the detachment of the stylus pen 168, initiates the operation of the accessory warning method (S701). That is, the accessory coupling state check unit 410 instructs the operation of the accessory loss prediction unit 412.
On the other hand, if the user is to move the portable terminal 100 with the stylus pen 168 withdrawn from the portable terminal 100, that is, when the user carrying the portable terminal 100 is moved, Since the distance between the stylus pen 168 and the portable terminal 100 increases, there is a concern that the stylus pen 168 may be lost. Accordingly, the accessory loss prediction unit 412 first activates the motion sensor included in the sensor module 170 to estimate the distance between the stylus pen 168 and the portable terminal 100. Receives data on displacements of the x, y, and z axes input from the motion sensor (S702).
Next, the accessory loss prediction unit 412 tracks the user's movement displacement by using data on displacements of the x, y, and z axes, thereby determining the distance between the stylus pen 168 and the portable terminal 100. It is estimated (S703). For example, the movement displacement of the user is tracked by checking how many steps the user has moved by reflecting a pattern of data on displacements of the x, y, and z axes as the user walks. This user's movement displacement tracking can be implemented using algorithms used in conventional pedometers (applications).
The accessory loss prediction unit 412 predicts that the stylus pen 168 may be lost when the predetermined threshold Th1 is reached using the tracked movement displacement tracking value of the user (S704-Yes). In operation S705, a signal indicating the loss prediction of the accessory is transmitted to the loss warning providing unit 413.
On the other hand, the loss warning providing unit 413 receives a signal indicating the loss of the accessory from the accessory loss prediction unit 412, by using a means that can be recognized by the user of the stylus pen 168 Generate a warning alarm indicating that there is a possibility of loss (S706). The warning alarm is a warning sound generated by reproducing a predetermined sound source through the speaker 163, the vibration of the portable terminal 100 by the operation of the vibration motor 164 provided in the portable terminal 100, and the display controller 194 And a message pop-up with a predetermined content through the display 193. The warning alarm issuing method may be provided in various ways in consideration of a stylus pen lost alarm setting of a user or a profile set in a portable terminal.
In addition, the loss warning providing unit 413 may repeatedly issue the warning alarm for each predetermined moving distance unit. To this end, the loss warning provider 413 may issue the warning alarm, and then request to repeatedly repeat the operation of issuing a signal indicating the warning alarm occurrence to the accessory loss prediction unit 412 (S707). -no).
In addition, through at least one of an input of a button 161 provided in the portable terminal 100, an input of a keypad 166 provided in the portable terminal 100, or a touch screen 191, the termination of the warning alarm is terminated. (S707-Yes), the operation can be terminated. End of the operation, the loss warning providing unit 413 provided in the first CPU 111 requests the accessory loss prediction unit 412 to terminate the accessory loss prediction operation (S708), the accessory loss prediction unit 412 ) May end the accessory loss prediction operation.
On the other hand, even if the accessory is detached from the portable terminal 100, if the user is used for the operation of the portable terminal, it is not necessary to proceed with the loss prediction operation of the accessory. Accordingly, when the accessory is detached from the portable terminal 100 and is used for the operation of the portable terminal 100, an interrupt signal is issued to proceed with the initialization of the accessory loss warning method (711). This issuance of the interrupt signal may be issued at any of steps S702 to S708, and operates to proceed with the initialization of the accessory missing warning method regardless of which step occurred.
For example, when the accessory interface 197 obtains a signal generated from the accessory, the accessory interface 197 acquires a signal from the accessory, and transmits information indicating this to the terminal status checker 411. to provide. When the terminal state checking unit 411 receives information indicating signal acquisition from the accessory, the terminal state checking unit 411 does not need to generate a warning alarm for loss. B, provided to the loss warning provider 413. Then, the accessory loss prediction unit 412 initializes the process of performing the accessory loss prediction. For example, the accessory loss prediction unit 412 of the motion sensor (or the GPS module 155, or the wireless LAN module 131, etc.) to initiate the tracking process of the user's movement displacement. The process proceeds to step S702 again for initializing and restarting the operation.
Similarly, the first CPU 111 provided in the portable terminal 100 may provide information indicating an operation state (activation state) as the operation state of the portable terminal 100 is switched to the activation state. To provide. When the terminal state checking unit 411 receives the information indicating the operation state (activation state) from the first CPU 111, the terminal state checking unit 411 does not need to generate a warning alarm for loss. The article loss prediction unit 412 or the loss warning providing unit 413 can be provided.
