1 is a flowchart illustrating an error handling method of a mobile terminal according to an embodiment of the present invention.

Referring to FIG. 1, an embodiment of an error processing method of a mobile terminal according to the present invention is a mobile terminal having an acceleration sensor, the method comprising: receiving at least one input from a user through an input unit of the mobile terminal; Comparing the measured value of the sensor with a threshold value that is a criterion for invalidating the input; and invalidating the input if the measured value of the acceleration sensor is greater than the threshold value have.

First, the mobile terminal is an information terminal that can be carried by a user and is used in various fields. For example, a portable telephone, a wireless telephone, a personal digital assistant (PDA), a palm personal computer (PC), a handheld personal computer (HHP)

In addition, the acceleration sensor is a device for measuring dynamic forces such as acceleration, vibration, and impact of an object. Acceleration sensors are used for various purposes as an indispensable device for a vehicle, a train, a ship, an airplane, a vehicle, a factory automation system, and a robot control system. In particular, acceleration sensors incorporated in communication devices are becoming smaller and more diverse. Preferably, it may be built in the mobile terminal, but may be provided separately from the mobile terminal.

Next, the step (S110) of receiving at least one input from the user through the input unit of the mobile terminal is a step of receiving a user's input through an input device such as a touch screen constituting the input unit of the mobile terminal.

The input unit may be a touch screen. However, the present invention is not limited to the touch screen, and may include various input devices such as a touch pad, a keypad, and a wireless input device.

At least one input received through the input unit in receiving at least one input from the user through the input unit of the mobile terminal is at least one input received through an input unit including a touch screen, a touch pad, and a keypad .

For example, at least one input received through the input unit may be a touch input using a touch screen as an input device. The touch input may be a touch input by touching one point, a touch input including touching one point, or a touch input may be a touch input that draws a specific trajectory after pressing one point. In addition, the touch input may be a multi-touch input that is input simultaneously or within a predetermined time interval.

Also, at least one input received through the input unit may be a touch input using a touch pad as an input device. As in the case of the above-described touch screen, the touch input through the touch pad may be a touch input by touching one point, a touch input including a pressing operation, or a touch input drawing a locus. In addition, the touch input may be a multi-touch input as well as a touch screen.

Also, at least one input received through the input unit may be a key input using a keypad as an input device. The user may press a number or a special character constituting the keypad to input a desired result. Also, the key input may be a multi-key input that is input simultaneously or within a predetermined time interval.

The at least one input may include all inputs that are input using a touch screen, a touch pad, and a keypad. That is, the touch input of the touch screen and the touch input of the touch pad may be combined, and the touch input of the touch screen and the key input of the keypad may be combined and input. May be combined and input.

For example, in the case of a mobile terminal having a touch screen and a keypad, there may be a touch input for touching one point on the touch screen and a key input for pressing the number '1' using the keypad. In the case of a mobile terminal having both a touch screen, a touch pad, and a keypad, a touch input that touches and touches one point on the touch screen, a touch that draws a trace from one point on the touch pad to another point There may be keystrokes that use the input and keypad to press the special character '#'.

In the step of receiving at least one input from the user through the input unit of the mobile terminal, the at least one input may be within a predetermined time interval based on a time at which the measured value of the acceleration sensor is confirmed. That is, since the probability that the at least one input and the time for confirming the measured value of the acceleration sensor are the same is very small, the at least one input may be a predetermined time interval based on the time of confirming the measured value of the acceleration sensor Is treated as at least one valid input.

For example, if the time at which the measured value of the acceleration sensor is confirmed is 12:00 am, and the predetermined time interval is 1 second, all inputs occurring within an interval of 1 second based on 12:00 am are input to the at least one input As shown in FIG.

The predetermined time interval may be a predetermined time interval including a time for confirming the measured value of the acceleration sensor. That is, in order for the measured value of the acceleration sensor and the at least one input to be related to each other, the input should occur within a time interval affected by the motion of the mobile terminal, which is a cause of the measured value of the acceleration sensor, Since the influence of the motion may be earlier or later than the time of the measured value, the predetermined time interval may have a special meaning only when the time interval includes the time to confirm the measured value of the acceleration sensor.

For example, when the measured value of the acceleration sensor corresponds to '5' and the threshold value to be used for invalidating the input is '4', the time for confirming the measured value of the acceleration sensor is 12 : 00, the predetermined time interval may correspond to a time interval including a time interval of 12:00, that is, a time interval from 0.5 seconds earlier than 12:00 minute to 0.5 seconds later than 12:00, As described above, the at least one input affected by the movement of the mobile terminal according to the measurement value can be treated as an error only when the 12:00 am angle is included.

The predetermined time interval may be specified by the user. That is, the predetermined time interval may be set to be wider or narrower considering the characteristics and exercise ability of each user.

For example, in the case of a user having excellent athletic performance, since the user can quickly cope with the motion of the mobile terminal, the influence of the motion of the mobile terminal will be relatively small. In this case, therefore, the predetermined time interval may be set to be as narrow as 0.5 seconds. On the contrary, in case of a user having low exercise ability, since the mobile terminal will be affected by the movement of the mobile terminal, the predetermined time interval can be set to 1.5 seconds.

In the step of receiving at least one input from the user through the input unit of the mobile terminal, the at least one input may be at least two inputs simultaneously. That is, from the viewpoint of the capability of the processor of the mobile terminal, two or more inputs can be inputted at the same time, and the input is called a multi input, and at least one input, which can be processed by the mobile terminal, Can be included.

For example, in a mobile terminal having a touch screen, a multi-touch input can be simultaneously performed using two fingers or a stylus pen as a touch input. Also, in a mobile terminal having a keypad and a general screen, two or more key inputs may be simultaneously input, that is, a number '3' and a special character '*'. In the case of the multi-input as described above, the mobile terminal can process all the multi-inputs into the at least one input.

Next, comparing the measured value of the acceleration sensor with a threshold value serving as a criterion for invalidating the input (S120) means checking the measured value of the acceleration sensor and comparing the measured value with the threshold value .

The process of checking the measured value of the acceleration sensor may be a process of reading a memory area in which the measurement value of the acceleration sensor can be confirmed by the control unit of the mobile terminal. Also, the process may be performed by providing an interrupt from the acceleration sensor to the control unit.

For example, when the measured value is measured by the acceleration sensor, an interrupt corresponding to the measured value is generated, and the controller reads the memory area in which the measured value is stored in the acceleration sensor in response to the interrupt signal to check the measured value .

The threshold to be used for invalidating the input may be designated by the user. That is, the threshold value may be designated by the user so as to reflect the difference of receiving or receiving the influence of the movement of the wireless terminal depending on the habit or the behavior of the user using the wireless terminal.

For example, in the case of a user who normally holds the mobile terminal firmly and uses the mobile terminal, the influence of motion of the mobile terminal is relatively less, so that the probability of occurrence of an input error is reduced even if the measured value of the acceleration sensor is large A user who loosely grasps the mobile terminal normally and operates the mobile terminal is likely to be influenced by the movement of the mobile terminal so that the probability of an input error may increase. Therefore, the user who holds the mobile terminal firmly must operate to set a threshold value that is a criterion for invalidating the input to be large, and in the opposite case, there is a need to set a small threshold value. .

Another embodiment of the error handling method of a mobile terminal according to the present invention may further include the step of designating a threshold value as a criterion for invalidating the input.

As described above, since it is necessary to set a threshold value as a criterion for invalidating the input, the step of setting the threshold value may be additionally configured to implement the error handling method of the mobile terminal.

Next, if the measured value of the acceleration sensor is greater than the threshold value, the step of invalidating the input (S140) may be such that the measured value of the acceleration sensor is greater than the threshold value when the movement of the wireless terminal is large , The input in this case is a step of invalidating the input because the probability of the error is high.

For example, if the wireless terminal has a large movement and the measured value of the acceleration sensor corresponding thereto is '7', if the threshold value is designated as '4', the user is within a predetermined time interval The input will likely be an error. In this case, the input by the user within the predetermined time interval will be treated as an error.

Referring to FIG. 1 again, another embodiment of a method of processing an error of a mobile terminal according to the present invention includes: selecting whether to invalidate the input if the measured value of the acceleration sensor is greater than the threshold value S130).

If the measured value of the acceleration sensor is larger than the threshold value, the step of selecting whether or not the input is invalid may be performed (S130). In this case, even if the movement of the wireless terminal is large, the input within a predetermined time interval may not be an error Therefore, the input at this time is an additional step configured to be able to process normally.

For example, if the wireless terminal has a large movement and the measured value of the acceleration sensor corresponding thereto is '6', if the threshold value is set to '4', the user is within a predetermined time interval The input will likely be an error. However, when the input by the user is not an error, it is necessary to normally process the input. In this case, the input by the user may not be processed as an error.

An input unit 210 for receiving at least one input from the user may be a touch screen 211, a touch pad 212, a keypad 213, and a wireless input device for receiving input from a user.

Receiving at least one input through the input unit 210 means receiving at least one input through an input device including the touch screen 211, the touch pad 212 and the keypad 213 as described above, And may include multiple inputs.

In addition, as described above, the at least one input may be within a predetermined time interval based on a time at which the measured value of the acceleration sensor is confirmed, and may be a predetermined time interval including a time for confirming the measured value of the acceleration sensor Lt; / RTI > In addition, the predetermined time interval may be designated by the user.

Next, the acceleration sensor 220 for measuring the acceleration value of the mobile terminal refers to a device capable of measuring the movement of the wireless terminal, in particular, the acceleration change, and notifying the user of the change.

As described above, the measurement value of the acceleration sensor 220 can be checked by the control unit 230, and can be compared with the measurement value and a threshold value used as a criterion for invalidating the input.

Next, when the measured value is greater than the threshold value, the controller 230 invalidates the user input within the predetermined time interval. Here, the input may be invalidated if the measured value is larger than or equal to the threshold value.
