Hereinafter, a method of inputting information in a mobile terminal and a mobile terminal according to an embodiment of the present invention will be described in detail with reference to the drawings.

In the present specification, the same or similar reference numerals are given to different embodiments in the same or similar configurations. In addition, it should be considered that the components of the drawings attached hereto can be enlarged or reduced for convenience of explanation.

As used herein, the singular forms "a", "an" and "the" include plural referents unless the context clearly dictates otherwise. Furthermore, terms including ordinals such as first, second, etc. used in this specification may be used to describe various components, but since the terms are used only for the purpose of distinguishing one component from another, The elements are not limited by these terms.

Referring to FIG. 2, an embodiment of the present invention may include an electronic pen 110 and a portable terminal 120. At this time, the electronic pen 110 may be detachably incorporated into the portable terminal 120 as a remote input means for the convenience of the user.

The electronic pen 110 includes an input sensing unit 111 and an ultrasonic transmission unit 112.

The input sensing unit 111 senses a user input. For example, the input sensing unit 111 may be a piezoelectric element. The piezoelectric element senses a user's input by recognizing the pressure when a user tries to input a character or a picture by applying a pressure on an object of the electronic pen 110 on an arbitrary object. However, the present invention is not limited thereto. The input sensing unit 111 may be of a switch type, and may be configured to sense the movement of the electronic pen 110 as a user input when the user turns on the switch And various other configurations are available.

When the user input is detected, the ultrasound transmitting unit 112 transmits the ultrasound signal to the portable terminal 120. The distance between the electronic pen 110 and the portable terminal 120 can be obtained by multiplying the time from when the ultrasonic signal is transmitted until the time when the portable terminal 120 receives the ultrasonic signal to the speed of the ultrasonic signal And the ultrasonic signal is used as a means for calculating the position of the electronic pen 110 disposed outside the portable terminal 120.

The portable terminal 120 includes an ultrasound receiver 121, a position information detector 122, a storage unit 123, a controller 124, and an output unit 125.

The ultrasonic receiving unit 121 receives ultrasonic signals transmitted from the ultrasonic transmitting unit 112 of the electronic pen 110. [ The ultrasonic receiving unit 121 may be formed of a plurality of sensors to calculate the position of the electronic pen 110. For example, at least three ultrasonic sensors may be disposed in at least three of the four corner regions of the portable terminal 120. The ultrasonic sensor may be a microphone formed in a conventional terminal.

The position information detection unit 122 may detect the position information of the electronic pen 110 by analyzing the ultrasonic waves received by the ultrasonic receiving unit 121. For example, when three ultrasonic sensors are provided, the distance between each ultrasonic sensor and the electronic pen 110 can be detected. Based on the three detected distances, the distance between the electronic pen 110 and the electronic pen 110 Three-dimensional coordinates can be obtained.

The storage unit 123 stores location information of a user input. For example, the storage unit 123 may serve as a buffer for temporarily storing user input before the user input is output to the output unit 125, and the stored information may be used by the control unit 124 have. In addition, the storage unit 123 stores information on locations of specific areas within the non-display area of the portable terminal 120 and information on events corresponding to the specific areas. For example, when the user performs touch input to the speaker 125b area of the portable terminal 120, information on the position of the speaker 125b area and an event to be output to the portable terminal 120 after touch input Is stored in the storage unit (123).

The controller 124 determines which function is to be performed for the sensed user input and analyzes the sensed user input. The control unit 124 may include a determination unit 124a, a search unit 124b, a text analysis unit 124c, and a drawing analysis unit 124d.

The determination unit 124a determines whether the position of the electronic pen 110 provided by the position information detection unit 122 is the display area of the portable terminal 120, Referring to FIG. 3, the display area 130a is an area for displaying an image on the front surface of the portable terminal 120. Here, the image includes a static image and a dynamic image (video) Concept. In the display area 130a, pixels of a display panel for displaying an image are provided. The non-display area 130b refers to an area of the front surface of the portable terminal 120 excluding the display area 130a. 3, the outer region 130c indicates all the regions except for the mobile terminal 120 although only a partial region is displayed in the outer region 130c. At this time, since the outer region 130c must be an area capable of receiving ultrasonic waves by the ultrasonic receiving unit 121, it is defined within a predetermined range distance from the portable terminal 120. [

If it is determined that the position of the electronic pen 110 is the non-display area 130b, the search unit 124b searches the storage unit 123 to see if an event corresponding to the position of the electronic pen 110 is stored. When a corresponding event is stored, the control unit 124 issues an instruction to the output unit 125 to execute the event.

If it is determined that the position of the electronic pen 110 is the display area 130a or the external area 130c, the determination unit 124a determines whether the form of the user input through the electronic pen 110 is a text form or a drawing form . If the user input is in text form, the text analysis unit 124c analyzes what the user input is. If the user input is a drawing type, the text analyzing unit 124c analyzes what drawing the user input is. Thereafter, the control unit 124 issues an instruction to the output unit 125 to display the analyzed text or drawing.

The output unit 125 outputs an event corresponding to the user input to the user for display. The output unit 125 may include a display unit 125a, a speaker 125b, an illumination setting unit 125c, and a camera 125d. The display unit 125a is a configuration for displaying an application to be executed or a text or a drawing inputted by the user. The display unit 125a includes a display panel, and may include a touch panel when detecting a part of a person's body. The speaker 125b reproduces sound according to the user input. The illumination setting unit 125c is configured to set the brightness of the display unit 125a, and can set different brightness depending on the time or the surrounding environment by the automatic lighting setting function. The camera 125d is a configuration that enables moving pictures or photographing. The output unit 125 outputs an output according to the type of the user input. For example, when a user input that touches the display area 130a of the portable terminal 120 is detected, the display unit 125a displays text or a drawing corresponding to the user input.

Hereinafter, an information input method of the portable terminal 120 according to an embodiment of the present invention will be described in detail with reference to FIG.

First, the display unit 125a of the portable terminal 120 (see FIG. 2) is turned on (S100). For example, when a user presses a button for turning on a screen of the portable terminal 120 in a black state in which no contents are displayed in the display area 130a (see FIG. 3) of the portable terminal 120, Is turned on and an initial image is displayed in the display area 130a. However, step S100 may be omitted. That is, step S100 may be omitted so that input through the electronic pen 110 (see FIG. 2) is detected even when the display area 130a of the portable terminal 120 is not activated.

In the next step, the portable terminal 120 senses a user input through the electronic pen 110 and receives an ultrasonic signal of the electronic pen 110 according to the user input (S101). For example, when the user presses the specific area with the electronic pen 110, the input sensing part 111 (see FIG. 2) of the electronic pen 110 such as a piezoelectric element senses a user input. Thereafter, the ultrasonic transmission unit 112 (see Fig. 2) transmits ultrasonic signals to the portable terminal 120. Fig.

2) receives the ultrasonic signal, and the position information detector 122 (see FIG. 2) detects the position of the user input (S102). The process of detecting the position information will be described in detail with reference to FIG.

5, the ultrasound receiving unit 121 of the portable terminal 120 may include three ultrasound sensors 121a, 121b, and 121c. The ultrasonic sensors 121a, 121b and 121c may be disposed in frontal areas adjacent to the vertexes of the non-display area 130b (see FIG. 3) of the portable terminal 120, respectively. At this time, the position of the stylus of the electronic pen 110, that is, the position of the user input, may be composed of three-dimensional information such as P (x, y, z). Thus, obtaining P (x, y, z) yields the position of the user input. The distance between the ultrasonic sensors 121a, 121b, and 121c and the tip of the electronic pen 110 can be determined according to the velocity of the ultrasonic signal and the arrival time of the ultrasonic signal, as described above. At this time, P (x, y, z) can be obtained by substituting the distance between the ultrasonic sensors 121a, 121b, 121c and the tip of the electronic pen 110 into a predetermined formula derived by the Pythagorean theorem.

Next, the control unit 124 (see FIG. 2) determines whether the detected position of the user input is the display area 130a, the non-display area 130b, or the outside area 130c (see FIG. 3) (S103). For example, considering the position coordinate lookup table stored in the storage unit 123 (see FIG. 2) by the determination unit 124a (see FIG. 2) of the control unit 124, Area.

If it is determined that the detected position of the user input is located within the display area 130a or the outer area 130c, the user input is analyzed according to whether the user input is text or drawing (S104). More specifically, the determination unit 124a determines whether the input content is a text or a drawing. If the text is a text, the text analysis unit 124c (see FIG. 2) (See Fig. 2).

Then, the analyzed text or drawing is outputted to the display unit 125a (see Fig. 2) (S105). For example, characters input by the user in a touch manner to the display area 130a of the portable terminal 120 or characters input through the electronic pen 110 in the external area 130c of the portable terminal 120 are displayed on the display 125a, Lt; / RTI >

On the other hand, if it is determined that the detected position of the user input is located in the non-display area 130b, it is determined whether an event corresponding to the position of the user input is searched (S106). The search unit 124b of the control unit 124 searches the storage unit 123 to see if an event corresponding to the position of the user input is stored. The storage unit 123 stores location information on a specific area and information on a specific event. The location information of a specific area in the non-display area 130b and the information of a specific event are stored in a matching manner. Therefore, if the location of the user input is not stored in the storage unit 123, or if there is no matching event information for a specific area, the event search is not performed.

At this time, when a specific event is searched, the control unit 124 instructs the output unit 125 (see FIG. 2) to output the event. At this time, depending on what kind of event and what kind of execution is performed, the output component may be changed.

Embodiments of a specific area in the non-display area 130b and an event matching the specific area will be described in detail with reference to FIGS. 6A to 6F.

The first embodiment executes an event that provides information requesting selection of an interface type for touch input to an input in a central area 131 at the upper or lower end of the non-display area 130b. At this time, a predetermined logo may be engraved on the central area of the upper or lower end of the non-display area 130b.

6A, when a user touches a logo engraved in the central area 131 at the lower end of the non-display area 130b through the electronic pen 110, A notification may be displayed asking which type of touch input interface to execute. The notification may be provided in various forms including a form of a pop-up window. The type of the touch input interface may include an automatic text execution interface that automatically executes a function related to text input to a user input text or a touch input window to be input by a user, A multitasking interface that is shown on the display 130a. The automatic text execution interface is an interface for, for example, allowing a user to immediately call a specific person when a text " call " is input, or to cause a telephone application to be executed. For example, the multitasking interface is activated such that a memo window capable of touch input is displayed on a part of the display area 130a so that the user can freely input data into the memo window. At this time, In the displayed disabled area, a screen before the multitasking interface is executed may be displayed.

The second embodiment executes an event that captures the content displayed in the display area 130a for the input in the camera area 132 or commands the execution of the camera application. This will be described below with reference to FIG. 6B.

At this time, as the user touches the camera area 132, an event to be executed may vary depending on what contents are displayed in the display area 130a. If a lock screen is displayed in the display area 130a for the first time, for example, when the power of the output unit 125 is turned on, the mobile terminal 120 displays the lock screen, Run the application. The executed camera application may provide a menu such as a camera photographing, a gallery providing, a photo editing, and the like, or may provide a photographing mode using a rear camera directly.

On the other hand, if the initial image is not displayed in the display area 130a when there is a user input, that is, not a lock screen that is first displayed when the output unit 125 is turned on, Captures an image displayed in the display area 130a at the moment when a user input is detected and stores the captured image in the storage unit 123. [ Saved photos can be viewed through the gallery.

In addition, when the camera area 132 is touched twice using the electronic pen 110 continuously within a predetermined time, the photographing mode through the front camera can be executed. For example, when the user double-clicks the camera area 132 with the electronic pen, the executed camera application immediately becomes the front camera shooting mode.

The third embodiment executes an event for executing the automatic lighting setting function of the display area 130a with respect to the input in the illuminance sensor area 133. [

The illuminance sensor is a sensor that detects the illuminance around the portable terminal 120 to adjust the brightness of the display area 130a of the portable terminal 120. [ The automatic light setting function is a function that allows the user to set different lights according to the environment in which the portable terminal 120 is used. For example, as shown in FIG. 6C, when the illuminance sensor area 133 of the portable terminal 120 is touched through the electronic pen 110, the automatic light setting function is executed. Accordingly, the brightness of the display area 130a of the portable terminal 120 may vary depending on an environment in which the user does not touch the display area 130a for a predetermined period of time.

The fourth embodiment performs an event that causes the speaker to be turned on for input to the speaker area 134 so that the sound is reproduced.

6D, when the user touches the speaker area 134 via the electronic pen 110, the speaker turned off is turned on and the sound is reproduced .

Additionally, if the speaker area 134 is touched twice continuously with the electronic pen 110 within a predetermined time for the speaker in the off state, an event for executing the music playback application can be executed.

In addition, when the speaker area 134 is touched with the electronic pen 110 when a telephone ring or a telephone receiving screen is displayed, an event for executing the speaker phone mode may be executed.

In the fifth embodiment, the volume of the speaker is raised or lowered for an input for dragging the electronic pen 110 in the upward direction or the downward direction in the left or right area 135a, 135b of the non-display area 130b Execute the event. At this time, the degree to which the volume is changed according to the length of the electronic pen 110 is varied.

For example, when the user drags the electronic pen 110 from the lower side to the upper side (① direction) in the left area 135a of the non-display area 130b, the volume of the speaker may be increased . Similarly, when the user drags the electronic pen 110 from the upper side to the lower side (in the direction (2)) in the left area 135a of the non-display area 130b, the volume of the speaker can be lowered. Also, the size of the volume may be changed depending on how much the electronic pen 110 is dragged upward or downward (in the direction ① or ②). Here, the setting of whether to increase or decrease the volume of the speaker in either direction (1) or (2) may be set differently from the above example.

As described above, the events corresponding to the plurality of areas can be set variously for a plurality of areas of the non-display area 130b. In particular, since an embodiment of the present invention utilizes not only the touch recognition method but also the ultrasonic recognition method, user input can be recognized even in the non-display area 130b instead of the display area 130a. In addition, since a function or an application desired by the user is immediately executed through a single touch input process, it is possible to simplify the function execution process of the portable terminal 120, thereby improving the convenience of the user.

If it is determined in step S103 that the position of the user input does not correspond to any one of the display area 130a, the non-display area 130b, and the external area 130c, the portable terminal 120 displays a feedback alarm (S108).

When the position of the user input does not correspond to any area, the portable terminal 120 can not recognize or display any input. Accordingly, no output is displayed on the portable terminal 120. However, if the user does not recognize that there is an error in the position of the user input, the user may wait for output without knowing the English language or fear that the portable terminal 120 malfunctions. Therefore, a feedback alarm is provided to prevent this.

Feedback alarms can be output in a variety of ways. For example, the feedback alarm may be a pop-up window for requesting re-entry on the display area 130a of the portable terminal 120, or may be a light-emitting device such as an LED (Light Emitting Diode) , Or a form in which a specific sound is reproduced through a speaker, or the like.

The user recognizes the feedback alarm and performs re-input. In the method of inputting the mobile terminal information according to an embodiment of the present invention, information input can be performed again from step S101.

Meanwhile, in the information input method of the portable terminal 120 according to the embodiment of the present invention, after the event is executed according to the user input in the non-display area 130b, the user touches the electronic pen 110 again at the same position The event to be executed may be terminated.

For example, when the camera shooting mode is being performed by touching the camera area, the camera shooting mode may be terminated by touching the camera area with the electronic pen 110 again. When the speaker is turned on by touching the speaker area, the speaker may be turned off by touching the speaker area with the electronic pen 110 again.

Meanwhile, in the information input method of the portable terminal 120 according to the embodiment of the present invention, a specific area in the non-display area 130b and an event corresponding to the specific area can be set by the user. The information input method as in the embodiment of the present invention is advantageous in that a specific function or application can be operated by a single touch. However, the predetermined functions or applications may be ones that are not mainly used by the user. In addition, since the position of the user input can be detected by an ultrasonic signal in any area within the non-display area 130b, the user can set a desired area. Accordingly, the mobile terminal 120 optimized for the user can be implemented by allowing the user to set a specific area and an event in the non-display area 130b.

The step of storing and setting the one area in the non-display area 130b and the one area in accordance with the user input will be described in detail with reference to FIG.

First, the portable terminal 120 includes an interface or an application capable of executing these steps. After this interface or application is executed (S201), the designation for one area of the non-display area 130b is input by the user to the electronic pen 110 (S202). The location information of the set area is stored in the storage unit 123 (S203).

Then, a user input for event setting to be executed corresponding to the set area is input (S204). At this time, the interface or application may provide a message for requesting the user to set an event through the display unit 125a, and a user may select a specific application or function according to the message, and an event desired by the user is designated. Information on the set event is stored in the storage unit 123 (S205). The stored event and the location information of the stored area are matched with each other (S206).

Through such a process, the user can set desired areas and events. Then, when an area set by the user is touched with the electronic pen 110 in the future, an event matching with the set area is executed.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments.
