≪ Embodiment 1 >

3A is a block diagram illustrating a configuration of a terminal apparatus according to an embodiment of the present invention.

3A, the terminal device 100 includes a body 110, a cover 120, a first sensor 130, a mount 140, a second sensor 150, and a controller 160 do.

The body 110 may be implemented in a form including an input / output unit. The input / output unit may be provided on the front surface of the body unit 110 to receive an input and display an output image corresponding to the input. For example, the input / output unit may include a touch screen. In this case, the input to the touch screen may be realized by touching or proximity of the object. Specifically, the touch screen may include a display panel and a touch panel.

The display panel may be a panel such as a liquid crystal display (LCD), an organic light emitting diode (OLED), or the like, and displays various images according to various operation states, application execution and services implemented in the terminal device 100.

The touch panel may be implemented by a first touch panel of an EMR (Electro Magnetic Resonance) method, but may further include a second touch panel of a capacitive type in some cases.

Here, the first touch panel of the EMR system is a touch panel which is stacked on the lower surface of the display panel and detects the contact of the EMR pen. Specifically, the first touch panel includes an electromagnetic induction coil sensor (not shown) having a grid structure in which a plurality of loop coils are arranged in a predetermined first direction and a second direction intersecting the first direction, And an electronic signal processing unit (not shown) for sequentially providing an AC signal having a predetermined frequency to each of the loop coils. Accordingly, when an input device (not shown) is built in the vicinity of the loop coil of the first touch panel so as to generate a current based on the electromagnetic induction, the magnetic field transmitted from the loop coil is inputted to the resonance circuit It is possible to generate a current based on mutual electromagnetic induction. Based on this current, an induction magnetic field is generated from the coil constituting the resonance circuit in the input device, and the first touch panel detects the induction magnetic field in the loop coil in the signal reception state, The touch position is detected. Meanwhile, the input device may be detachably attached to the body 110, but may be provided separately from the body 110 as the case may be. In the present embodiment, it is assumed that the input device is detachably attached to the body 110. [

On the other hand, in the second touch panel, a thin metal conductive material such as ITO (Indium Tin Oxide) is coated on both sides of the glass, as in an ITO panel, so that electric current can flow on the glass surface, And may be implemented as a panel coated with a dielectric. Specifically, when an object is brought into contact with the display panel, a predetermined amount of charge moves to the contact position by the static electricity at a position contacting the second touch panel, and the second touch panel displays a change amount of the current And detects the touched position. The second touch panel can sense any touch capable of generating static electricity, thereby detecting touch by a user's hand or detecting contact through an input device such as a stylus pen.

Meanwhile, in the above-described embodiment, the second touch panel is implemented as the capacitive touch panel. However, the second touch panel is not limited to the capacitive touch panel, and may be implemented by various methods such as a resistive method or an ultrasonic method. In addition, although the first touch panel has been described with an EMR type touch panel as an example, the present invention is not limited thereto as long as the input device and the first touch panel are interlocked with each other and are responsive to contact or proximity of the input device.

The cover 120 may be formed to cover the entire surface of the body 110 (FIG. 1A).

The first sensor unit 130 detects whether the cover unit 120 is open or closed. That is, it detects whether the cover 120 is in contact with the body 110 or not. Specifically, the first sensor unit 130 may be mounted on the body 110 to detect whether the cover unit 120 is open or closed, based on signals relating to a contact area, a contact position, and the like. For example, the first sensor unit 130 can detect that the cover unit 120 is closed when the contact area is larger than a predetermined size, or when contact is detected at a predetermined contact position.

For example, when a conductive material having a capacitance is disposed on at least one predetermined region of the cover 120, the first sensor unit 130 may contact the cover member 120 when the cover unit 120 is closed, Signal.

However, the present invention is not limited to the above-described embodiment, and the present invention is not limited to this, as long as it is capable of detecting whether the cover 120 is open or closed.

The mounting portion 140 may be a space in which the input device is mounted, and the mounting portion 140 may be provided with the second sensor portion 150. The second sensor unit 150 is a sensor for detecting the detachment of the input device. That is, the second sensor unit 150 detects a state where the input device is inserted into the mounting unit 140 and fixed, or detects the state where the input device is detached from the mounting unit 140. [ Here, the second sensor unit 150 may be implemented by a button method or a switch method.

FIG. 4 is a view for explaining a case where a mounting part is implemented as a button according to an embodiment of the present invention.

4, when the second sensor unit 150 is implemented as a button, the second sensor unit 150 may be provided at the inner end of the mounting unit 140. [ In this case, when the input device 10 is inserted into the mounting part 140, the second sensor part 150 is pressed by the end of the input device 10, whereby the second sensor part 150 is pressed by the input device 10 May be mounted on the mounting portion 140.

On the other hand, the control unit 160 controls the overall operation of the terminal device 100.

Particularly, the controller 160 controls the operation of the input unit 10 when the cover unit 120 covers the body 110, that is, when the cover unit 120 is closed, When it is detected, the first touch panel, which detects the input of the input device 10, can be controlled to be activated. That is, the control unit 160 can control the activation state of the first touch panel based on the detection signals of the first sensor unit 130 and the second sensor unit 150 in a state in which the first touch panel is inactivated .

The control unit 160 activates the first touch panel when the input unit 10 is detached from the mounting unit 140 while the cover unit 120 is closed, It is in a standby mode state in which the contact signal can be received.

Accordingly, when the cover 120 is closed and a paper such as a notepad is placed on the cover 120 and the handwriting is performed, the user can recognize the handwriting trajectory and make a note, The memo inputted through the touch panel can be recognized, so that the memo function can be performed even when the cover unit 120 covers the screen. In this case, however, the input device 10 needs to be realized not only by the EMR function but also by an actual handwriting device.

On the other hand, when the input device 10 is inserted into the mounting portion 140 and mounted, the first touch panel is inactivated and can enter the sleep mode. Accordingly, the cover 120 can not sense the input signal when the body 110 is closed.

When the controller 160 detects that the input device 10 is disconnected from the mount 140 while the cover 120 is in contact with the body 110, It is possible to control the pre-set application to be driven at the same time. Here, the predetermined application may be a memo application.

Accordingly, even when the cover 120 covers the screen, the memo performed using the actual paper notepad can be executed and stored through the memo application.

The sensor unit 230 senses whether the cover unit 220 is in contact with the body 210. For example, the sensor unit 230 may include a Hall sensor. The hall sensor uses an element whose internal resistance is changed by a magnetic field, and the output is changed in response to a device such as a magnet provided in the cover portion 220. The sensor unit 230 can sense whether the cover unit 220 is opened or closed based on the output change.

The control unit 240 may control the display unit 220 to display a predetermined image in a region corresponding to the transparent window among the display panel regions in a closed state.

The control unit 240 performs a first function for the input of the region corresponding to the transparent window in the closed state of the cover unit 220 and a second function for the input of the remaining region except for the region corresponding to the transparent window, Can be performed.

Specifically, the control unit 240 performs a memo function for the input of the area corresponding to the transparent window, and performs a menu function related to the memo function corresponding to the input gesture with respect to the input of the remaining area excluding the area corresponding to the transparent window Can be performed.

Here, the menu function related to the memo function may be at least one of a memo page navigation function, a memo delete function, a memo save function, and a zoom in / out function.

3C is a block diagram illustrating a configuration of a terminal device according to an embodiment of the present invention.

3C, the terminal device 300 includes a body 310, a cover 320, a sensor 330, and a controller 340. The body part 110, the cover part 120, the first sensor part 130, and the second sensor part 130 shown in FIG. 3A, which are the description of the body part 310, the cover part 320, the sensor part 330, Will not be described in detail.

The body part 310 includes an input / output part.

The cover part 320 may be attached to or detached from the body part 310 and may be implemented in a form in which a sub screen (for example, E-paper) is mounted on the entire surface (FIG. 2C). Specifically, the E-paper may be mounted on the entire area of the screen of the body 310.

The sensor unit 330 senses the contact state of the cover unit 320 with respect to the body unit 310.

The controller 340 controls the body part 310 through the cover part 320 based on the contact state of at least one predetermined first area of the body part 310 and at least one predetermined second area of the cover part 320 310). ≪ / RTI > Here, the contact state of at least one predetermined first region of the body 310 and at least one predetermined second region of the cover 320 may be in a position corresponding state of each region. That is, when a note is made in a state that the cover part 320 is closed, an input error when the coordinate position of the cover part 320 and the body part 310 are changed can be corrected.

At least one predetermined first region of the body 310 includes at least one of the four corners of the body 310 and at least one predetermined second region of the cover 320 includes And four corner regions of the cover portion 320. [0052] As shown in FIG. However, the present invention is not limited thereto as long as it can calculate the correspondence between the body part 310 and the cover part 320.

At least one predetermined first region of the body 310 and at least one second region of the cover 320 may comprise a conductive material. In this case, the control unit 340 determines the contact position of at least one predetermined first region of the body 310 and at least one second region of the cover 320 based on the capacitance change of the conductive material It can be judged.

Meanwhile, in order to increase the memo utilization for each of the three types of cover, it is necessary to recognize whether the cover is opened or closed, whether or not the pen is detached, whether or not the note is made, and the like. Specifically, the cover type, whether or not the cover is opened or closed, how to recognize whether the memo is started or completed, the operation when the cover is opened after the memo is created, a plurality of memo writing and management control methods, operation scenarios and methods And a brief description of these parts will be given below.

<Whether opening / closing according to the type of cover and memo input situation>

The terminal can recognize whether the cover is opened or closed according to the type of the cover through the operation of the various sensors and the memo input state corresponding thereto.

In the case of the flip cover covering the front surface according to the first embodiment of the present invention, when the terminal is in a dormant state, the proximity sensor always detects proximity, and when the pen is detected during proximity detection, The situation can be recognized.

Further, in the case of a cover including a transparent window in one area, it is possible to detect a close operation of a hole sensor or a proximity sensor, detect the closing of the hall sensor or pen disconnection during proximity detection, If there is, it can be recognized that the memo input situation. In this case, the cover type can be recognized through the hall sensor. That is, in the case of the cover including the transparent window, since the hall sensor is mounted, the cover type can be recognized based on whether the hall sensor is operated or not.

Further, in the case of the smart cover equipped with the sub-screen, when the hall sensor closing operation or the proximity sensor proximity is detected and the hall sensor is closed or the pen separation is detected during proximity detection, It can be recognized. In this case, the cover type can be recognized through the cover interface. That is, in the case of a smart cover equipped with a sub screen, since the sub screen and the main screen can be interfaced through a separate smart interface, the cover type can be recognized based on whether the corresponding smart interface is operated or not.

As described above, in order to recognize whether the cover is open or closed, a pen separation sensor, a proximity sensor, and a hall sensor may be utilized. That is, when the pen is taken out and input, the state of the proximity sensor and / or the hall sensor can be checked and the open / close state of the cover can be grasped. Thus, it is possible to check the open / closed state of the cover, to know the correct type of cover through whether the hall sensor is operated or the smart interface is mounted.

For example, if you check the proximity sensor periodically, you can check if the cover is installed. It can be judged that the cover is always open, but it is generally possible for the user to close the cover and make a living. Therefore, it is possible to determine whether the cover is mounted by checking the proximity sensor periodically.

If the pen is detached while the cover is closed, proximity detection of the pen can indirectly determine whether or not the pen is used. It is possible to detect a case where the pen comes close to the screen to exclude the case where the pen is not used or the pen is lost. When the proximity sensor detects the proximity of the pen, it can be seen that the cover is closed.

Next, determine whether the smart cover interface (a predetermined interface connecting the cover with the sub screen and the terminal main body) is connected. Whether the smart cover is attached or not can be determined through connection of the smart cover interface.

If it is judged that the smart cover is not mounted, it is determined whether or not the Hall sensor is present. If there is no Hall sensor, it can be recognized as a flip cover covering the front because it does not support transparent window (for example, S-View) operation. In this case, the flip cover that covers the front surface also operates as a copier other than the regular S-view cover.

On the other hand, if the smart sensor interface is not connected, it can be judged that the S-View cover is installed.

<How to know whether the memo started or completed>

The terminal can perform necessary applications through the division of the start and completion of the memo creation or upload the memo to the server.

The start of the memo operation can be recognized by hovering detection when the cover is closed, regardless of the type of cover, and when the pen comes close to the screen after the pen is detached. In this case, the terminal device can execute a memo application and enter a standby state for entering a memo.

Further, in the case of the flip cover covering the front surface, it is possible to recognize completion of the memo operation when the pen is coupled to the terminal device or when the cover is opened, in such a manner that the completion of the memo work for each cover type is recognized.

Further, in the case of a cover including a transparent window in one area, completion of the memo operation can be recognized when the pen is coupled to the terminal device or the cover is opened, or when there is a gesture input outside the transparent window area.

Further, in the case of the smart cover having the sub screen, the completion of the memo work can be recognized when the pen is coupled to the terminal device, the cover is opened, or when the menu is selected using the pen.

In other words, the completion of the memo is recognized when the pen is no longer used, or when the cover is opened, and the memo created in this situation is stored in the memory and backed up to the server. In addition, periodic storage in real time during memo writing can be basically supported.

<Operation of the terminal when the cover is opened after the completion of the memo>

When the cover is opened after all the memos have been written, the operation method of each cover type may be changed.

Specifically, in the case of a cover including a front cover or a cover including a transparent window in one area, if the number of newly created memos is displayed on the memo application icon, or when the pen is detached from the mounting unit in a state that the cover is opened, (Thumbnail) can be displayed.

In the case of the smart cover having the sub screen, the icon is continuously displayed on the upper side of the note while the cover is closed, and when the cover is opened, the note disappears from the E-Paper when the cover is opened. In addition, the number of newly created memos may be displayed on the memo application icon. In addition, when the pen is detached from the mounting portion in the state that the cover is opened, thumbnails can be displayed from the recently created memo to the memo recently created.

<Adding and managing notes>

To add multiple notes, you need to add a note. You can simply add the notes and combine them again.

However, if you continue adding without pen combination, the method of adding notes may vary depending on the cover type.

For example, in the case of a flip cover that covers the front, a new memo page can be created by combining and disassembling the pen. Alternatively, a new memo page can be created via the pen gesture input. In this case, haptic feedback can be provided when a new memo page is generated. Alternatively, it is possible to create a new memo page by opening and closing the cover. In this case, the pen may be in a separated state.

In the case of a cover including a transparent window in one area, a new memo page can be generated through finger touch. Alternatively, a new memo page may be created through a pen input gesture (e.g., &lt; - &gt;) for next page selection in the transparent window outer area.

In the case of a smart cover with a secondary screen, you can create a new memo page by clicking the menu with the pen.

<Information protection function of memo contents>

How you protect your memo from being leaked by others can vary by cover type.

In the case of a flip cover that covers the front, the screen is not visible, so there is no need to perform any special operations to protect the information. In the case of a cover including a transparent window in one area, the screen disappears immediately when the flip cover is turned on again. Do.

However, in the case of a smart cover equipped with a sub-screen, the contents posted on the E-Paper remain as they are for several months without switching to another E-paper screen, so that information can be protected only by switching or deleting the screen. In this case, the easiest and most intuitive operation will allow the post to disappear when the pen is removed for information protection. In this case, a new page may be set to expand. Alternatively, there may be a method of protecting information by switching to a page editing screen when the pen is detached and by allowing the user to delete the contents directly. In this case, a menu such as page deletion can be provided on the edit screen.

Hereinafter, a method of inputting a memo through the cover portions of various forms described above with reference to the drawings will be described in detail.

6 is a diagram for explaining a memo input method according to the first embodiment of the present invention.

6, when the cover 110 covers the entire surface, the cover 110 covers the entire screen of the terminal device 100, so that the interaction through the screen and / You will not be able to receive feedback.

In this case, the most important point is that the memo content itself should be shown to the user when the memo is made using the pen. In order to support this, a simple sticky note 610 that can be affixed to the cover 110 and an EMR pen 10 'combined with ink or a pencil can be used. As a result, using EMR binding pen, which has already been commercialized, EMR digital input becomes possible while writing directly on paper. Therefore, there is an effect that the paper need not be scanned separately.

In this case, if the EMR pen 10 'is disconnected from the terminal device 100 while the cover part 110 is closed, the terminal device 100 determines that the intention is to make a note in the closed state of the cover part 110 , And the touch pad can be activated to enter a standby state for receiving a memo input. In addition, the memo application can be automatically operated to enable the memo function to be performed through the memo application.

In addition, the terminal device 100 may provide predetermined feedback on the pen input. For example, you can provide sound feedback that is written squarely on paper. In addition, the terminal device 100 can provide predetermined feedback when the memo input ends. For example, the user can be informed that a note has been stored via feedback of at least one of haptic and sound. In addition, even when a note is newly generated, it is possible to provide predetermined feedback.

FIGS. 7A and 7B and FIGS. 8A to 8D are views for explaining the operation of the terminal device according to the second embodiment of the present invention.

When the cover 220 includes a transparent window 221 as shown in FIG. 7A, the image can be confirmed through the transparent window 221, so that when the user writes in the transparent window 221, You can take notes while watching the contents. In this case, it is possible to distinguish the pen input from the finger touch, so that the control by the menu linkage or the gesture can be performed.

Specifically, as shown in FIG. 7B, a memo function is performed for pen input, and an additional menu function (a navigation function, a storage function, a delete function, a zoom in / out function, etc.) . For example, you can move to the next page by dragging with your finger while typing with a pen on the notepad.

It is also possible to perform an additional menu function related to the memo function through pen input in an area not including the transparent window 221 as shown in FIGS. 8A to 8D.

Specifically, a deletion gesture (e.g., X), a page navigation gesture (e.g., →, ←), a note storage gesture (e.g., For example, Z), a zoom in / out gesture (for example, Z), and the like.

In addition, although not shown in the drawing, when the pen 10 is pulled out in a state in which the cover part 220 is closed and a certain time has elapsed after the notepad has been formed, the main display is turned off due to power saving. (220) is opened, the contents of the memo can be displayed on the screen.

9A to 9C are diagrams for explaining the operation of the terminal device according to the third embodiment of the present invention.

As shown in FIG. 9A, when the E-paper 910 is mounted on the front surface of the cover part 320, the entire surface can be used as a note paper. In this case, since the area for inputting the EMR pen is wide enough, various menu driving and gesture utilization are possible. Also, if the E-Paper is on the front of the cover, it will have a big advantage of Always On.

Specifically, even when power is not supplied, E-Paper keeps the image intact, so that information can be always displayed. In addition, it can be used as a display for viewing e-books and various information notifications.

However, from the point of view of pen input, in case of smart cover with E-paper, if EMR pen solution of smart phone body is utilized, one problem should be solved. Specifically, the coordinate position of the E-Paper on the front face of the pen input sensor of the smart phone body and the front face of the cover is correct, so that the same screen output for the pen input can be made. Even if the front face of the cover is slightly twisted, accurate display output to the pen input can not be made and pen tip error may occur. Therefore, a device and a method for correcting the deformation of the cover should be provided (see FIG. 9B).

For this, an electrostatic touch sensor of the terminal device 300 can be utilized as shown in FIG. 9C. Concretely, at least one conductive substance 921 to 924 capable of touch sensing is attached to the inner surface of the cover portion 320, that is, the inner surface of the cover which comes into contact with the main screen when the cover is closed. In this case, when the cover part 320 is closed, the electrostatic touch sensor can recognize the coordinates of the inside surface of the cover, and the coordinates can be compared with the reference coordinates to measure the extent to which the cover part 320 is distorted .

In this case, after measuring the degree of misalignment in the reference coordinates, the position of the output image of the E-Paper corresponding to the pen input is restored to the opposite direction by a wrong degree (for example, the pen input coordinate is rotated and rotated) It is possible to make the output at the pen end position at the time of input correctly.

In the case of Smart Cover with E-paper, if the sensitivity of the sensor is increased, it is possible to touch input while covering the cover in addition to the purpose of coordinate correction. Since the touch action is detected through the change of the capacitance detected by the touch sensor, the touch sensor can be used to control the degree of menu selection.

FIG. 10 shows a screen when a cover is opened and a cover is opened after a note is closed according to an embodiment of the present invention.

The created memo disappears from the display according to the user's need or the display is turned off. An update, that is, the number of the newly created memo is displayed on the memo application icon 20. As shown in the figure, a number "3" is written in the update mark 21. You can tell the number of newly created memos through the number display on these icons.
