Description

TECHNICAL FIELD [0001] The present invention relates to a method and a system for controlling a smart terminal operation using a 3D touch,

The disclosed technique relates to a method and system for controlling the operation of a smart terminal using a 3D touch.

In general, a terminal such as a smart phone is equipped with a screen for sensing a touch of a user, and detects at which point on the screen the touch is performed using the x-axis and the y-axis on the screen.

Furthermore, it is possible to detect not only a point to be touched but also a certain point to another point. Recently, the user interface is formed in a manner different from the conventional one by sensing the strength of a touch rather than a simple touch.

In one embodiment, referring to Apple's 3D touch, a new user interface is being constructed by applying a technology that differentiates the intensity of a touch using a pressure sensor, as well as simply tapping or dragging a finger, to an Apple iPhone or an iPhone.

Meanwhile, in recent years, it is possible to detect not only the pressure applied to the touch but also the position where the pressure is applied on the screen, so that it is expected that a more various user friendly interface will be developed.

Korean Patent Laid-Open No. 10-2015-0122014 (titled "Temporary operating method and terminal for operation target according to touch pressure and touch area") is known as a conventional technology for using 3D touch.

1 is a flowchart illustrating a smart terminal operation control method using a 3D touch according to an embodiment of the disclosed technology. Referring to FIG. 1, a smart terminal operation control method using a 3D touch includes the following steps.

In step 110, the smart terminal senses the pressure. The smart terminal includes a display unit, and a predetermined screen is mounted on the display unit. The user of the smart terminal can touch one point on the screen using a finger or smart pen or the like, and can apply pressure by pressing the touch point. Accordingly, the smart terminal can sense the pressure applied to the screen.

In one embodiment, the smart terminal may operate only the pressure sensing sensor except for other functions or modules so as to be able to wait for the user's pressure in a locked state.

On the other hand, the display unit not only senses the pressure but also senses that a pattern corresponding to a user's touch is input. In order to sense the pressure and the pattern, the display unit includes a pressure sensing sensor and a touch sensing panel.

In an exemplary embodiment, the display unit senses a pressure applied to the screen using the pressure sensing sensor, and senses a pattern input by the user using the touch sensing panel.

Meanwhile, the pressure sensing sensor operates when the smart terminal is in the locked state, and the touch sensing panel operates when the smart terminal is in the first mode.

In one embodiment, when the smart terminal is in the locked state, the pressure sensing sensor is activated, and when the smart terminal is switched to the first mode, the touch sensing panel may be activated. Therefore, battery consumption of the smart terminal can be minimized.

In consideration of the fact that the power consumption of the pressure sensor is normally considerably small, the pressure sensor always operates without discriminating between the locked state and the first mode, disables only the touch sensing panel, And may be activated in the first mode.

In step 120, the smart terminal is switched to the first mode when it detects a pressure applied to the screen. The smart terminal includes a controller, and the controller switches the smart terminal to the first mode according to the pressure.

Here, the controller may provide feedback to the user of the smart terminal upon switching to the first mode. In one embodiment, the smart terminal may be vibrated according to the pressure to recognize that the user of the smart terminal is entering the first mode.

Meanwhile, in step 120, the smart terminal keeps the screen in an off state. And recognizes a pattern input by the user in the inactive state of the screen.

In one embodiment, the controller recognizes that the pressure is transmitted through the screen as a signal for switching to the first mode. At this time, the controller can keep the screen as it is and can wait for a pattern to be inputted by the user.

Generally, a user interface of a smart phone activates a screen using a battery so that a user can visually confirm a tapped point or a pattern to be input. However, in the disclosed technology, the control unit keeps the screen of the smart terminal in a disabled state However, it internally senses the pressure or pattern of the user and controls the sensors or modules so that the operation can be performed accordingly.

Referring to FIG. 4, it can be seen that a pressure and a pattern are inputted in a state in which the screen is inactive according to an embodiment of the disclosed technology. In sensing the pressure through the screen, the disclosed technique uses a pressure sensing sensor included in the display portion as described above. The pressure sensor senses the pressure of the user at a point on the screen of the smart terminal.

When the smart terminal is switched to the first mode according to the pressure, the controller uses a touch sensing panel included in the display panel to recognize a pattern input by the user.

Here, the pressure sensing sensor is activated while the smart terminal is in the locked state, and senses the pressure, but the touch sensing panel is in an inactive state. When the smart terminal is changed in the first mode according to the pressure, the pressure sensing sensor is inactivated and the touch sensing panel is activated.

In order to distinguish whether the user mistakenly applied the pressure to the screen or the user interface, the controller controls at least one of the intensity of the pressure, the number of times the pressure is input, and the position at which the pressure is input And stores the reference value in advance. Then, the smart terminal is switched to the first mode by comparing the reference value and the pressure.

In one embodiment, when the controller determines that the pressure is transmitted to the screen of the smart terminal, the controller compares the pressure and the pressure intensity of the stored reference value. When the intensity of the pressure inputted to the screen exceeds the pressure intensity of the reference value, The smart terminal can be switched to the first mode.

Meanwhile, when the smart terminal is switched to the first mode, the controller receives a pattern through a screen. The control unit can recognize that the user draws a dot on the screen of the smart terminal, draws a line, and draws a graphic. That is, the pattern has a shape including at least one of a point, a line and a surface. For example, it is possible to use a plurality of points as a pattern, or a number or a pattern as a pattern.

Also, the controller may receive a long touch as the pattern. That is, in the first mode, it is sensed that the touch is maintained at a certain point over a predetermined time, and it can be recognized as a specific pattern. In one embodiment, if the user is in an urgent or confusing situation such that he or she can not input the missing 119 or 112, it is possible to use the pattern to operate a specific application by simply touching the screen for a long time.

In addition, the control unit can receive at least one pressure in the pattern. In one embodiment, it is possible to use the pattern as pressure again after switching to the first mode according to the pressure. It is possible to use a user interface according to the technique which is started by applying pressure only to the screen in a situation where it is difficult to input a predetermined pattern as in the case of the chapter input.

Meanwhile, when the smart terminal is switched to the first mode, the controller operates the touch sensing panel of the display unit to receive a pattern input by the user through the screen of the smart terminal. If the first mode is entered and the pattern is not received within the time limit, the smart terminal may be returned to the locked state.

In step 130, when the pattern is input through the screen, the controller controls the operation of the smart terminal so that the application stored in the smart terminal is executed according to the pattern. In one embodiment, the smart terminal includes a memory for storing at least one application, and the controller can execute a specific application mapped to a pattern input from at least one application stored in the memory.

3, the controller includes a mode switching module for switching the smart terminal to the locked state or the first mode, a mode switching signal for switching the smart terminal to the first mode according to the pressure, A signal processing module for generating an operation control signal by comparing the pattern with a previously stored pattern, and a control module for controlling the screen and executing the application according to the operation control signal.

In one embodiment, when a pressure is detected on the screen of the smart terminal, the mode switching module switches the smart terminal to the first mode according to the mode switching signal generated by the signal processing module, When the signal processing module generates the operation control signal in comparison with the pre-stored pattern, the control module can execute the application stored in the memory.

Meanwhile, the control unit provides a user interface so that a user can customize a pattern by himself / herself. It is possible to create and store at least one pattern through the user interface, and set the applications mapped to the at least one pattern.

In one embodiment, the user interface receives a pattern including at least one of point, line, face, and chapter input, and sets the input pattern to be mapped to a specific application.

Meanwhile, according to an embodiment of the disclosed technology, it is desirable to recognize a pattern while keeping the screen of the smart terminal inactive, but it is necessary to activate the screen to adjust the direction, angle, or other matters of the screen , It is possible to recognize the pattern or differentiate the execution of the application by varying the number of times of pressure.

In one embodiment, the controller may deactivate the screen of the smart terminal once the pressure is sensed once, and may activate the screen when the pressure is sensed twice. If the user is using a phone call or recording or voice recognition application, it is not necessary to activate the screen, so it is necessary to enter the pressure only once to keep the screen of the smartphone inactive and check the camera or other screen When using the application, the pressure can be input twice.

Therefore, basically, it is possible to notify the operation of the smart terminal to the other person through the inactivation of the screen or to minimize the battery consumption, and it is possible to activate the screen and use it more precisely, if necessary.

Meanwhile, various embodiments according to the technique disclosed with reference to FIG. 5 will be described below. Referring to FIG. 5, when the controller receives the pattern corresponding to the emergency phone number, the controller can transmit a call to an organization corresponding to the corresponding number using the calling application of the smart terminal.

In an actual emergency situation, it is troublesome to unlock the terminal, execute a call application and enter a call by inputting 119 or 112, and it is not easy to release the lock if the terminal is not the terminal itself. The emergency call can be performed quickly. In addition, there is also the advantage of being able to report to the paramedics or the police station in secret because other people can not see that they are using the device on the surface.

In addition, although not shown in the drawing, when the controller receives the pattern corresponding to the speed dial, the controller sends a call to the contact mapped on the speed dial among the contacts stored in the smart terminal using the calling application of the smart terminal It is possible.

In an embodiment, when a phone call is made to a person who has stored a contact, such as a family member, a lover or a friend, a call application is usually executed to input a shortcut key of a corresponding person to perform a call. There is an advantage that a telephone conversation can be performed easily.

Meanwhile, in another embodiment, the control unit may execute a recording application or a voice recognition application of the smart terminal when receiving a pattern corresponding to recording or voice recognition. In addition, the controller may execute the camera application of the smart terminal upon receiving the pattern corresponding to the image photographing.

In the former case, since it is related to audio control applications, it is possible to easily execute the application by inputting the pressure only once. In the latter case, it is necessary to view the screen in order to shoot the object. Therefore, there is an advantage of controlling the user interface according to the type and situation of the application.

In one embodiment, if the user is in an urgent or confusing situation such that he or she can not input the missing 119 or 112, it is possible to use the pattern to operate a specific application by simply touching the screen for a long time.

Also, the controller 220 can receive at least one pressure in the pattern. In one embodiment, it is possible to use the pattern as pressure again after switching to the first mode according to the pressure.

In one embodiment, when the smart terminal is switched to the first mode, the control unit 220 operates the touch sensing panel 210c of the display unit 210 to display a pattern input by the user on the screen 210a ). ≪ / RTI > If the pattern is not received within the time limit after switching to the first mode, the smart terminal may be returned to the locked state.
