Description

Apparatus and method for input selection of a mobile terminal {APPARATUS AND METHOD FOR SELECTING A INPUT IN TERMINAL EQUIPMENT HAVING A MULTI TOUCH INPUT DEVICE}

The present invention relates to an input device and a method of a portable terminal, and more particularly, to an apparatus and a method for selecting an input in a portable terminal having a multi-touch input device.

In general, the current terminal device includes a touch panel and performs operation control and data input of the device through the touch panel. In this case, the touch panel mainly uses a capacitive method and a resistive film method for detecting a user's finger touch. In this case, when inputting data using a device using the touch panel, a keypad (keypad of Korean, English, numbers, etc.) for inputting data is displayed, and when the character area on the keypad is touched, the terminal is touched. A method of recognizing and determining input data is used.

However, when using the touch panel, it was not possible to accurately input characters and pictures. Therefore, devices using a pen for precisely inputting a handwriting input or a picture input such as a line have been developed. For example, Electro Magnetic Resonance (EMR) technology adds an EMR sensor pad below the LCD to detect pen input through resonance between the sensor pad and the pen. In the following description, an input unit for detecting a finger touch is called a touch panel, and an input unit for detecting a pen touch is called a pen input detection unit.

As described above, when a pen input and a finger input are mixed and used in a mobile terminal having a touch panel and a pen input sensing unit, an unwanted operation may be performed when two inputs are generated at the same time. For example, even if a mobile terminal wants to generate touch input using a pen, the user receives both finger touch and pen input, which causes unwanted input by finger or palm or wrist touch when writing or drawing with a pen. There is a problem that arises. That is, there is no way to completely prevent unwanted input in a mobile terminal capable of generating multiple inputs such as a pen and a finger. Therefore, there is a need for a method of selecting an input using a pen and a priority of input using a finger in a portable terminal device that processes multi-touch inputs.

The present invention proposes an apparatus and method for preventing a user from inputting an unwanted input by knowing an input method desired by a user in advance in a portable terminal having a multi-input device.

To this end, the present invention proposes an apparatus and method for operating in a pen mode when the pen is detached from the portable terminal by checking whether the pen is mounted in the portable terminal.

In addition, the present invention provides an input device corresponding to the input (pen or finger) to perform the unlocking at the time when the portable terminal transitions to the operation mode (for example, when unlocking the pattern, unlocking through the password input) An apparatus and method for activating are proposed.

In addition, the present invention proposes a device and method for switching to a pen mode when a pen input is detected for a set time in a mobile terminal having a multi-input device.

A portable terminal device according to an embodiment of the present invention, the portable terminal device according to an embodiment of the present invention, the input unit including a touch panel for sensing a finger input and a pen input sensing unit for sensing a pen input, and by the pen input Set a pen mode when the terminal lock release, characterized in that the control unit for processing the operation of the mobile terminal by the pen input detected in the pen mode, and a display unit for displaying the terminal lock release screen.

In addition, the input selection method of the portable terminal device according to an embodiment of the present invention, the process of displaying the terminal lock release screen, the input unit consisting of a touch panel for sensing a finger input and a pen input sensing unit for detecting a pen input, And a process of setting a pen mode upon detecting the terminal lock release by the pen input, and processing an operation of the mobile terminal by a pen input in the pen mode.

 In the mobile terminal with multi-input function, pen input and finger input can be selected efficiently. This prevents malfunction due to other input such as a finger in pen mode in which a pen is used for drawing or taking notes. The advantage is that the user can activate only the desired input.

Hereinafter, with reference to the accompanying drawings a detailed description of preferred embodiments of the present invention will be described in detail. It should be noted that the same components in the figures represent the same numerals wherever possible.

The present invention proposes an apparatus and method for automatically setting or releasing a touch input mode by analyzing inputs inputted from terminal devices having two or more different touch input functions. In this case, the touch input may be a pen input or another input (a hand or finger touch input, in the following description, a finger touch input). The finger input may be a first input and the pen input may be a second input. In addition, the touch includes a state in which the touch is in contact with the touch panel and a state in which the touch is not in contact with the touch panel (spaced at a predetermined interval) and can be detected by touch.

An embodiment of the present invention proposes an apparatus and method for selectively activating a pen or finger touch input in a mobile terminal having touch panels capable of sensing a pen input and a finger input.

First, in the embodiment of the present invention, the pen use mode may be set by distinguishing whether the pen is mounted in the mobile terminal. In this case, the pen is set to a pen mode that accepts only a pen touch input when the pen is detached from the portable terminal and set to a finger use mode when the pen is mounted.

Secondly, when the terminal lock mode is released, the input mode is set according to the type of input that generates the terminal lock release input. That is, if the terminal unlock input is a pen input, it is set to a pen mode, and a finger input is set to a finger mode. Here, the terminal lock mode of the portable terminal may be set in various forms by the type of the terminal and / or the user. For example, the terminal lock mode may be released by unlocking the pattern lock or entering a password. Can be.

In general, when switching from the active mode to the standby mode, the mobile terminal turns off the display operation by controlling the display unit. Then, when the user wants to operate the mobile terminal in the display off state, first activate a display unit by pressing a specific button (for example, home buttoon). At this time, when the initial display unit is turned on, the terminal is in the terminal lock mode. If the terminal lock mode is to be released, the terminal lock mode must be canceled by a setting method (touch interaction, pattern unlock, password input or push unlock). do. In the embodiment of the present invention, when the user releases the terminal lock mode by using the pen when the terminal lock mode is released, the portable terminal detects this and subsequent input activates only the pen input. That is, when the terminal lock mode is released by the pen input, the portable terminal ignores inputs other than the pen input. In addition, when the terminal lock is released by a finger touch in the terminal lock mode, the portable terminal activates a finger input. At this time, when activating the finger input, the mobile terminal can ignore the pen touch input (ie, finger touch only mode), or can activate both finger input and pen input (finger and pen input combined mode).

In the pen mode, when the user mounts the pen on the portable terminal or presses a specific button (for example, when a short press of the power button), the portable terminal detects this and switches from the pen mode to the finger use mode. For example, if you want to use another input method such as finger input again in pen mode, the user can use the power button to perform standby mode or screen off, and then turn on the screen again. This can be done by unlocking the pattern terminal as an input method.

In addition, when the user wants to switch from the finger mode to the pen mode, the mobile terminal may automatically switch to the pen mode when the pen detects the set time. For example, it may be a case where a pen input is sensed for a predetermined time in the finger mode (here, when a pen contact or hovering is detected through the pen input sensing unit) or a pen is detected for a predetermined time through a camera.

In the following description, the terms finger input, finger touch, and finger touch input will be used in the same sense, and the terms pen input, pen touch, and pen touch input will also be used in the same sense. In addition, in the embodiment of the present invention, the terminal lock may be in a state in which the terminal device does not operate for a predetermined time and is switched to the standby state, and when the terminal device is to be operated in the terminal lock state, a lock state set in the terminal lock screen Should be released. The terminal lock screen may be displayed when a button (for example, a home button, a power button) is pressed, and the terminal lock screen may be displayed as a standby screen, a pattern lock screen, a slide lock unlock screen, or a password input screen. The user may release the terminal lock through the touch interaction or the number input of the set type. In the following description, the term terminal lock will be used interchangeably with the term lock.

Hereinafter, the present invention will be described with reference to the accompanying drawings.

1 is a diagram illustrating a configuration of a terminal device according to an embodiment of the present invention. Here, the terminal device may be various digital devices such as a mobile phone, an MP3 terminal, a tablet, a computer, etc., including a smart phone as a mobile terminal.

Referring to FIG. 1, the communication unit 120 performs a wireless communication function with a base station or another device. The communication unit 120 may include a transmitter for frequency up converter and power amplification of a transmission signal, a receiver for low noise amplification and a frequency down converter of a received signal, and the like. In addition, the communication unit 120 may include a modulator and a demodulator. Here, the modulator modulates the transmission signal and transmits it to the transmitter, and the demodulator demodulates the signal received through the receiver. In this case, the modulation and demodulation unit may be LTE, WCDMA, GSM, etc., may also be WIFI, WIBRO, etc., may be NFC, Bluetooth, and the like. In the embodiment of the present invention, it is assumed that the communication unit 120 includes LTE, WIFI, and bluetooh communication units.

The controller 100 controls the overall operation of the mobile terminal, and sets the pen mode or the finger use mode by analyzing the input according to an embodiment of the present invention. The controller 100 may set the pen mode or the finger use mode according to whether the pen is mounted. In addition, the controller 100 may set a pen mode or a finger use mode according to the type of input input when the terminal lock mode is released.

The memory 110 may include a program memory for storing an operating program of the terminal and a program according to an exemplary embodiment of the present invention, and a data memory for storing tables for operating the terminal and data generated during program execution.

The display unit 130 displays information of an application running under the control of the controller 100. The display unit 130 may be an LCD or an OLED. The touch panel 140 may be implemented in a capacitance capacitance method or a resistive film method, and outputs location information of a user's touch (hereinafter, referred to as a finger touch) to the controller 100. The second terminal panel 150 may include an EMR sensor pad, and detects a pen input and outputs it to the controller 100. The display unit 130, the touch panel 140, and the ERM panel 150 may be integrally formed.

The sensor 160 detects a signal related to whether the pen is mounted on the portable terminal and outputs the signal to the controller 100. The camera 170 captures an image and outputs it to the control unit 100. In an embodiment of the present invention, the camera 170 may capture and transmit the pen image to the control unit 100.

In the mobile terminal having the above configuration, the control unit 100 displays information on the display unit 130. When a touch is generated at a specific position of the display unit 130, if the finger touches, the touch panel 140 outputs touch information to the control unit 100. The pen input detection unit 150 outputs pen touch information to the control unit 100. In this case, the display unit 130, the touch panel 140, and the pen input sensing unit 150 may be integrated. In an exemplary embodiment of the present invention, the touch panel 140 is mounted on the upper portion of the display unit 130, and the pen input sensing unit 150 is disposed below the display unit 130. Can be mounted. That is, the display unit 130 may be integrated with the touch panel 140 and the pen input sensing unit 150 in a stacked form. In addition, the pen input detection unit 150 may be an ERM sensor pad. In addition, in the embodiment of the present invention, if the pen is an electronic pen, a touch panel for sensing a finger touch (which may be a capacitive touch panel) 140 and a pen input sensing unit for sensing a pen input (here It is assumed that it is configured as an ERM touch panel, but when two inputs use the same touch method (for example, when the pen is a capacitive type instead of an electronic pen), one touch Panels can be used. In this case, the control unit 100 may distinguish the pen input and the finger input by the size of the touch area when the input is detected through the touch panel.

2 is a flowchart illustrating a procedure of activating a specific input in a mobile terminal having a multi-input function according to an embodiment of the present invention.

Referring to FIG. 2, the controller 100 reads the output of the sensor 160 in step 211 to analyze whether the pen is mounted. Here, the sensor 100 generates a first detection signal when the pen is inserted (mounted) into the portable terminal, and generates a second detection signal when the pen is detached (that is, the pen is removed from the portable terminal). Therefore, if it is detected that the pen is released, the control unit 100 detects this in step 213 and sets the pen mode in step 215. When setting to the pen mode, the controller 100 deactivates the touch panel 140 and activates only an input detected through the pen input detector 150. Therefore, input generated by a hand (or finger) or the like during pen input is ignored, and only the pen input can be processed. Here, the pen mode refers to a mode that can display a function or a screen that can be performed according to a pen input. For example, when the pen mode is set, the controller 100 displays an application screen on the display 130 that can perform a function set according to a pen input. For example, in the terminal device of the Samsung Galaxy Note series, the pen mode can be used to perform various applications such as memo (S memo), planner (S planner), dialy, and e-mail.

However, if it is detected in step 213 that the pen is mounted, the controller 100 sets the finger usage mode in step 217. In the case of setting the finger using mode, the controller 100 activates the input of the touch panel 140, and thus processes the input (finger or hand input, etc.) detected through the touch panel 140 normally. In this case, when the finger use mode is set, the controller 100 may activate the input of the pen input detection unit 150 and may also deactivate the input. That is, in the finger use mode, the controller 100 may perform a finger-only mode for ignoring pen input and may also perform a finger / pen combined mode for normally processing pen input.

3 is a flowchart illustrating a procedure of activating a specific input in a mobile terminal having a multi-input function according to another embodiment of the present invention.

Referring to FIG. 3, the controller 100 performs a standby mode when the portable terminal is not operated and turns off the display of the display unit 130 in the standby mode. When the user wants to drive the mobile terminal while the display unit 130 is turned off, the user must press a specific button and release the terminal lock mode in a set manner when the screen for unlocking the terminal is displayed on the display unit 130. The specific button may be a home button. When the home button is pressed while the display unit 130 is off, the control unit 100 detects this and displays a screen for releasing the terminal lock mode in step 311. In this case, the terminal locking mode may be set in various forms. 4A to 4D are diagrams illustrating an example of a terminal lock release screen when a user input is waited to release the terminal lock mode. 4A illustrates a screen when a terminal lock mode is not set by a user, FIG. 4B illustrates a screen when a pattern lock is set, and FIG. 4D illustrates a screen in the case of releasing a lock by inputting a password.

When a terminal unlock input is generated while one of the screens of FIGS. 4A to 4D is displayed, the controller 100 detects this in step 313 and checks whether the terminal unlock input is a pen input in step 315. That is, while the terminal unlocking screen shown in FIGS. 4A to 4D is displayed, the user may generate an input for unlocking the terminal by using a pen or a finger. In this case, when the terminal unlocking input is generated by the pen input as shown in FIGS. 5A, 5C, 5E, or 5G, the control unit 100 detects the terminal unlocking by the pen input in step 315 and the pen mode in step 317. Set it. However, when the terminal unlock input is generated by the finger input as shown in FIGS. 5B, 5D, 5F, or 5H, the controller 100 detects the terminal unlock by the finger input in step 315 and uses the finger in step 319. Set the mode. 5A to 5H are diagrams illustrating an example of generation of an input for releasing a terminal lock mode in a mobile terminal.

As described above, in the embodiment of the present invention, the mobile terminal analyzes an input generated to release the terminal lock mode, and when the terminal lock mode is released by the pen input, the controller 100 deactivates the touch panel 140 and detects the pen input. Set pen mode to activate only 150. Therefore, when the pen mode is set, the controller 100 controls the operation of the mobile terminal by a pen input detected through the pen input detecting unit 150 and ignores other inputs detected through the touch panel 140. However, when the terminal lock mode is released by a finger input, the controller 100 activates the touch panel 140. In this case, in the finger use mode, the control unit 100 may activate or deactivate the pen input detection unit 150. When the finger use mode is set, the controller 100 controls the operation of the mobile terminal by a finger input sensed through the touch panel 150.

As described above, it is possible to switch to the finger use mode while operating by the pen mode input. 6 is a flowchart illustrating a procedure for switching from a pen mode to a finger touch mode in a mobile terminal according to an embodiment of the present invention.

Referring to FIG. 6, in step 611, the controller 100 processes a pen input while performing a pen mode. In this case, the control unit 100 displays the pen input detected through the pen input detecting unit 150 on the display unit 130, and controls the operation of the mobile terminal by the pen input. When the pen is mounted in the portable terminal in the above state, the sensor 160 detects this and outputs a pen mounting detection signal to the controller 100. Then, the control unit 100 detects this in step 613 and switches to the finger use mode in step 615. That is, when it is detected that the pen is mounted on the portable terminal, the controller 100 activates the touch panel 140 and operates the portable terminal according to an input detected by the touch panel 140 (in this case, a finger touch). To control.

In addition, when detecting the pressing of a specific button in the pen mode (for example, if a short press of the power button is detected, the controller 617 detects this, and in step 619 the terminal unlock screen on the display 130) In this case, the terminal lock release screen may be one of the terminal lock release screens as shown in Figs. 4A to 4D, while the terminal lock release screen is displayed as shown in Figs. 5B, 5D, and 5F. Alternatively, when the terminal unlocking input is generated by the finger input as shown in Fig. 5h, the control unit 100 detects the terminal unlocking by the finger input in step 621, and sets the finger use mode in step 623. Using the finger as described above When the mode is set, the controller 100 controls the operation of the mobile terminal by the user's finger input detected through the touch panel 140.

As described above, in the state of performing and controlling the operation of the mobile terminal by the input of the finger mode, the controller 100 may switch to the pen only mode. 7 is a flowchart illustrating a procedure for switching from a finger mode to a pen mode in a mobile terminal according to an embodiment of the present invention.

Referring to FIG. 7, in step 711, the controller 100 performs a finger mode for performing and controlling an operation of the portable terminal by a finger input detected through the touch panel 140. When the pen departure detection signal is received through the sensor 160 while performing the finger mode as described above, the control unit 100 detects this in step 713 and switches to the pen mode in step 715. When switching to the pen mode, the control unit 100 performs and controls the operation of the mobile terminal by a pen input detected through the pen input detecting unit 150 as described above.

8 is a flowchart illustrating another procedure of switching from a finger mode to a pen mode in a mobile terminal according to an embodiment of the present invention.

Referring to FIG. 8, in step 711, the controller 100 processes and controls an operation of the mobile terminal by a finger input sensed through the touch panel 140. In this case, in the finger mode, the control unit 100 may activate the pen input detection unit 150 or may not activate it. That is, the controller 100 may detect and process only an input received through the touch panel 140 in a finger mode, and may detect and process both inputs of the touch panel 140 and the pen input detector 150. In this case, when both the touch panel 140 and the pen input detecting unit 150 operate in the finger mode, the pen input detecting unit 150 may detect whether the pen is touched. The touch may include both a state in which a pen is in contact with the pen input detection unit 150 and a state in which the pen is not in contact but may have a pen (hovering state). In this case, when a pen input is detected from the pen input detection unit 150 in the finger mode, the pen input time is detected in step 713 and the pen touch time is counted. In step 717, the pen input time is detected and the input mode of the portable terminal is detected. Switch from pen mode to pen mode. That is, the controller 100 switches to the pen mode when the pen input is detected for more than the time set by the pen input detector 150 in the finger mode, and then processes and controls the operation of the mobile terminal by the pen input.

In addition, when the camera 170 is turned on in the finger mode, the controller 100 may control the input operation of the portable terminal to the pen mode when a pen is detected through the camera 170. That is, when the pen is detected through the camera 170 in the state of executing and controlling the operation of the mobile terminal in the finger mode in step 711, the pen detects it in step 713 and counts the pen detection time from the output of the camera 170. If the time elapses, the controller detects this in step 717 and switches the input mode of the portable terminal from the finger mode to the pen mode. That is, the controller 100 switches to the pen mode when the pen is detected for more than the time set by the camera 170 in the finger mode, and then processes and controls the operation of the mobile terminal by the pen input.

As described above, when the pen is sensed in the finger mode for processing and controlling the operation of the mobile terminal by the finger input sensed through the touch panel 140, the pen input mode may be switched. In this case, the pen detection may be performed through the pen input detection unit 150 and / or the camera 170. When the pen is detected for a predetermined time, the control unit 100 may switch from the finger mode to the pen mode to control and process the operation of the mobile terminal. Can be. In addition, as described above, the terminal lock screen is displayed through a specific button (for example, a short press of a power button) while executing a function through the mobile terminal, and the terminal unlock screen is input through a pen on the terminal lock screen (corresponding to When a touch interaction or a password set in the terminal lock mode is generated, the controller 100 may switch from the finger mode to the pen mode.

As described above, the terminal apparatus includes a touch device that accepts pen input and a touch device that receives additional input such as a finger touch. In this case, the touch device may be composed of two or more independent touch devices (for example, a capacitive touch panel for sensing a finger touch and an ERM touch panel for sensing an electronic pen touch, etc.) and one touch. It can be configured as a device. In this case, when configuring a single touch device, the pen may be made of a material capable of generating the same touch input as a finger.

The terminal device having the configuration as described above operates in a pen-only mode when performing a corresponding operation with a pen input in an operation of making a device available, such as screen unlock, password unlock, and pattern lock release when the pen input is used exclusively. If you use the device for other types of input, such as finger touch, and make the device available for screen unlock, password unlock, pattern unlock, etc. Etc., it works with the input method you want.

In addition, when the pen is fixed on the device screen for a certain time before the pen is held in the device at the time of unlocking or in the finger use mode, the pen can be operated only in pen input mode. And if the pen is checked by the camera built into the device, the pen can be operated only by pen input.

Embodiments of the present invention disclosed in the specification and drawings are only specific examples to easily explain the technical contents of the present invention and aid the understanding of the present invention, and are not intended to limit the scope of the present invention. It will be apparent to those skilled in the art that other modifications based on the technical idea of the present invention can be carried out in addition to the embodiments disclosed herein.
