Description

Method of correcting touch input error using sensor of mobile communication terminal and mobile communication terminal performing the same {Method of Correcting Touch Input Error by using Sensor for Mobile Equipment and Mobile Equipment performing the same}

The present invention relates to a mobile communication terminal having a touch input error correction method and a touch input error correction method, and more particularly, to a touch input error correction method using a sensor and a mobile communication terminal performing the same.

Modern information devices provide various functions and services to meet the needs of users, while a keypad having a fixed matrix arrangement is still mainly used as a user input device. For example, even when a display screen of color and high resolution is adopted as an information device, and the appearance and slimness and miniaturization are in progress, the user input device has not changed much from the conventional keypad type input device.

As an alternative to the user interface using such a keypad, many of the recently produced information devices employ a touch type user interface such as a touch pad or a touch screen. This is the result of reducing the cost of the touch interface device and the problem of low reliability and life of the conventional touch interface device.

A touch pad is a flat plate equipped with a pressure sensor. When a touch is made using a finger or a pen, the touch pad senses pressure to move an indicator on the screen, and the computer recognizes the position information.

The touch screen includes a position sensor that outputs the coordinates of the touch point when a point on the display screen is touched with a finger or the like. For example, a device in which the display screen serves as a touch pad may be defined as a touch screen.

Such touch-type input devices include a pressure resistive film method, a contact capacitance method, a surface acoustic wave (SAW) method, an infrared light sensing method, and a piezoelectric method. Among them, the pressure-sensitive resistive method which is high in transmittance, fast in response and excellent in resistance is less affected by the operating environment.

The touch screen can provide a user with an interactive and immediate correspondence between the contents displayed on the screen and the contents input through the screen, and can provide various types of inputs in various ways to provide high user satisfaction and convenience in use. have. That is, as a concept of integrating an output device and an input device constituting a user interface as compared to a standard user input device such as a keypad having a fixed arrangement, various types of inputs and outputs can be simultaneously performed. In particular, while changing from a conventional low-resolution text-based interface consisting of numbers and letters to a high-resolution graphic-based interface, it is possible to realize input through graphic-based objects, and to replace the keypad, the keypad installation area is omitted. As a result, it is possible to display a large screen relatively in an information device having the same volume.

However, despite the development of touch pad and touch screen related technologies, there is a technical limitation depending on the natural environment in the method of accurately determining the touch input. That is, the general parts may have different characteristics according to the operating environment, and in the case of the touch pad and the touch screen, the characteristics according to the operating environment of the components constituting the touch pad and the touch screen will be reflected as they are.

Therefore, the method of determining the touch input in the conventional touch pad and the touch screen is necessarily accompanied by an error value due to the operating environment, that is, temperature, humidity and pressure.

An object of the present invention is to provide a touch input error correction method using a sensor for detecting an external environmental factor.

1 is a flowchart illustrating a touch input error correction method using a sensor according to an embodiment of the present invention.

Referring to FIG. 1, in the touch input error correcting method using a sensor according to an exemplary embodiment of the present disclosure, a step of receiving a touch input for detecting a position coordinate in a mobile communication terminal (S110), correction according to external environmental factors It may be configured to include the step (S120) of correcting the position coordinates using the value and outputting the corrected position coordinates (S130).

First, a sensor refers to a device for detecting external environmental factors. Since the external environmental factor may include at least one of temperature, humidity, and pressure, the sensor may be at least one of a thermometer for sensing temperature, a hygrometer for sensing humidity, and a pressure gauge for sensing pressure.

For example, the sensor as a device for detecting external environmental factors may be composed of a thermometer and a hygrometer, or may be composed of a thermometer, a hygrometer and a pressure gauge, and the sensor may be configured by the thermometer alone.

Next, the step of receiving a touch input (S110) may be to receive a touch input using at least one of a touch pad and a touch screen. Any one of the touch pad and the touch screen is provided with a touch input using a user's finger or a stylus pen, and the touch input may be represented by a position coordinate or a position coordinate. That is, not only the position coordinate but also the value representing the trajectory and / or the pressure value representing the degree to which the touch screen is pressed may be expressed.

For example, when a touch input is expressed by using position coordinates, the touch input on the user's touch pad or touch screen may be represented by position coordinates having a coordinate value, and thus (1.0, 2.2) or (2.1, 3.2). ) May be expressed in such a manner as

Next, the step of correcting the position coordinates using the correction value according to the external environmental factors (S120) refers to correcting the user's touch input position coordinates by reflecting the position coordinate correction value according to the external environmental factors. In other words, the corrected position coordinate is calculated by merging correction values according to external environmental factors based on the position coordinate according to the user's touch input.

For example, when the position coordinate according to the user's touch input is (1.0, 2.2), if the position coordinate correction value due to an external environmental factor corresponds to (+ 0.1, + 0.0), it is corrected by merging the two data. If we get the position coordinates, it will be (1.1, 2.2).

Here, the position coordinate correction value according to the external environmental factors may be managed in the form of a database reflecting the change of the external environmental factors. When the external environmental factor is temperature, the position coordinate correction value according to temperature may be managed in the form of a database. When the external environmental factor is temperature and humidity, the position coordinate correction value according to the change of temperature and humidity is data. It may be managed in the form of a base, and it will be appreciated that the position coordinate correction value can be managed in the form of a database including external environmental factors.

Next, the step (S130) of outputting the corrected position coordinates includes receiving a touch input for detecting the position coordinates (S110) and correcting the position coordinates using a correction value according to external environmental factors ( It may be a step of providing a position coordinate value corrected through the step S120 to the processor of the mobile communication terminal.

The processor of the mobile communication terminal is a block for controlling voice calls, video calls, and various functions of the mobile communication terminal. When a corrected position coordinate is input, the processor of the mobile communication terminal is connected using a touch input through a touch pad or a touch screen. Corrected position coordinates can be used when controlling the operation.

For example, even when the position coordinate according to the user's touch input is (1.0, 2.2), the position coordinate correction value is (+ 0.1, + 0.0), and thus the corrected position coordinate is (1.1, 2.2). In addition, the device outputs the corrected position coordinates (1.1, 2.2), and the device receiving the corrected position coordinates, such as a processor, will control the connected operation using the corrected position coordinates (1.1, 2.2).

2 is an exemplary diagram for describing a database used in a touch input error correction method using a sensor according to an embodiment of the present invention.

Referring to FIG. 2, it can be seen that the position coordinate correction value of the touch input according to the change in temperature, which is one of external environmental factors, can be managed in the form of a database. As the temperature changes by 5 ℃ by the measured value of the thermometer sensor, it shows the database which expresses the position coordinate correction value in mm unit, and the database which manages the position coordinate correction value is used for several measurement. It may be a database set in advance.

For example, when the temperature is 20 ° C to 25 ° C, the position coordinate correction value does not need to be corrected to (0.0, 0.0), but when the temperature is 30 ° C to 35 ° C, (-0.1mm,- 0.1 mm). In addition, when the temperature is 10 ℃ to 15 ℃ will have a coordinate correction value of (+ 0.1mm, + 0.1mm).

3 is a flowchart illustrating a touch input error correction method using a sensor according to another exemplary embodiment of the present invention.

3, the touch input error correction method using a sensor according to another embodiment of the present invention further comprises the step (S300) of detecting an external environmental factor to provide a correction value according to the external environmental factors. Can be.

In order to provide a correction value according to the external environmental factors, the detecting of the external environmental factors (S300) may be performed by detecting an external environmental factor separately from the step S310 of receiving a touch input for detecting the position coordinates. It may be to determine in advance which position coordinate correction value to use in the database of.

The detecting of the external environmental factor (S300) may be sensing using at least one of a polling method and an interrupt method. This may be to determine the position coordinate correction value to be reflected by periodically reflecting the external environmental factors detected by the sensor at regular time intervals, and to generate the interrupt when the change of the external environmental factors by the sensor is detected to correct the position coordinates. It may be determined by reflecting on the value. In addition, it may be to determine the position coordinate correction value by applying both methods.

For example, a thermometer sensor is periodically detected every 10 seconds to determine if there is a change in temperature, and if the change in temperature is enough to change the position coordinate correction value in the database, change the position coordinate correction value. You can do it. Alternatively, it may be determined whether the detected temperature is enough to change the position coordinate correction value of the database, and the position coordinate correction value may be changed according to the determination result.

To calculate the position coordinate correction value by reflecting the sensor unit 420 for providing a detected value and the detected value of the sensor unit, and calculating the detected position coordinate and the calculated position coordinate correction value of the touch input unit. It may be configured to include a correction unit 430 for outputting the corrected position coordinates.

First, the touch input unit 410 for receiving the touch input and detecting the position coordinate may be provided with the touch input using at least one of the touch pad and the touch screen. The touch input unit 410 may generate and output a position coordinate before correction according to the touch input.

Next, the sensor unit 420 for detecting an external environmental factor and providing a detection value may detect the external environmental factor using at least one of a polling method and an interrupt method. Since the sensor unit 420 may include at least one of a thermometer, a hygrometer, and a pressure gauge, the sensor unit 420 periodically detects a change in at least one of temperature, humidity, and pressure according to a polling method, or uses an external time using a time required according to an interrupt method. Changes in environmental factors can be detected.

Next, a correction unit for calculating the position coordinate correction value by reflecting the detected value of the sensor unit and outputting the corrected position coordinate by using the detected position coordinate and the calculated position coordinate correction value of the touch input unit ( 430 may include a storage unit 431 for storing the position coordinate correction value according to the detected external environmental factors in the form of a database.

Here, the storage unit 431 may store and manage the position coordinate correction value according to the change of the external environmental factors in the form of a database, and the correction unit 430 may store the corrected position coordinate reflecting the position coordinate correction value. It may output to the processor of the mobile communication terminal. Therefore, the processor of the mobile communication terminal may perform the operation of being connected using the corrected position coordinates.
