Representative sensors among various sensors that may be included in the sensing unit 140 will be described in more detail.

First, the proximity sensor 141 refers to a sensor that detects the presence or absence of an object approaching a predetermined detection surface or an object existing in the vicinity using the force of an electromagnetic field or infrared rays without mechanical contact. In the proximity sensor 141, the proximity sensor 141 may be disposed in an inner area of the mobile terminal surrounded by the touch screen described above or near the touch screen.

When the touch screen is a capacitive type, the proximity sensor 141 may be configured to detect the proximity of the object by a change in the electric field according to the proximity of the conductive object. In this case, the touch screen (or touch sensor) itself may be classified as a proximity sensor.

On the other hand, for convenience of explanation, the action of allowing an object to be located on the touch screen without being in contact with the object to be recognized as being positioned on the touch screen is named "proximity touch", and the touch The act of actually touching an object on the screen is called "contact touch". A position at which an object is touched in proximity on the touch screen means a position at which the object is vertically corresponding to the touch screen when the object is touched in proximity. The proximity sensor 141 may detect a proximity touch and a proximity touch pattern (eg, a proximity touch distance, a proximity touch direction, a proximity touch speed, a proximity touch time, a proximity touch position, a proximity touch movement state, etc.). have. Meanwhile, as above, the controller 180 processes data (or information) corresponding to the proximity touch operation and the proximity touch pattern sensed through the proximity sensor 141, and further, provides visual information corresponding to the processed data.

The touch sensor may be configured to detect a position, an area, and a pressure at the time of a touch on the touch sensor by a touch object applying a touch on the touch screen. Here, the touch object is an object that applies a touch to the touch sensor, and may be, for example, a finger, a touch pen, a stylus pen, or a pointer.

In this way, when there is a touch input to the touch sensor, the signal(s) corresponding thereto is transmitted to the touch controller. The touch controller processes the signal(s) and then transmits the corresponding data to the controller 180. Accordingly, the controller 180 can know which area of the display unit 151 has been touched. Here, the touch controller may be a separate component from the controller 180 or may be the controller 180 itself.

Meanwhile, the controller 180 may perform different controls or perform the same control according to the type of the touch object by touching the touch screen (or a touch key provided in addition to the touch screen). Whether to perform different controls or the same control according to the type of the touch object may be determined according to an operating state of the mobile terminal 100 or an application program being executed.

The ultrasonic sensor may recognize location information of a sensing target by using ultrasonic waves. Meanwhile, the controller 180 may calculate the location of the wave generator through information sensed from the optical sensor and a plurality of ultrasonic sensors. The location of the wave generator may be calculated by using a property that the light is much faster than that of the ultrasonic wave, that is, the time that the light reaches the optical sensor is much faster than the time that the ultrasonic wave reaches the ultrasonic sensor. More specifically, the position of the wave generator may be calculated using a time difference between a time when the ultrasonic wave arrives using light as a reference signal.

Meanwhile, the camera 121 is a type of camera sensor, viewed as the configuration of the input unit 120, and the camera sensor includes at least one of a camera 121, a photo sensor, and a laser sensor.

The photosensor may be stacked on the display device, and the photosensor is configured to scan the motion of a sensing object close to the touch screen. More specifically, the photo sensor scans the contents placed on the photo sensor by mounting a photo diode and a transistor (TR) in a row/column and using an electrical signal that changes according to the amount of light applied to the photo diode. That is, the photosensor may calculate the coordinates of the sensing object according to the amount of light change, and through this, the location information of the sensing object may be obtained.

5 to 34 are explanatory diagrams illustrating a control process of a smart watch type mobile terminal according to an embodiment of the present invention.

4 to 34, when the screen of the circular touch screen 151 is turned on, the controller 180 applies two or more touch keys included in an input method editor (IME) to the circular screen borders, respectively. Arranged and displayed [S110], and when a first touch input for at least one touch key is received [S120], an operation associated with at least one character assigned to the at least one key is controlled [S130].

At this time, the touch keys are assigned two or more characters, such as at least one national language, alphabet, number, and special character, respectively, and as shown in FIG. 5, like 12 hours of a clock, the touch keys are They are arranged and displayed at positions corresponding to each 12 hours within the border of the shape of the screen.

At this time, since all characters belonging to a specific character mode (native language mode, English mode, number mode, and special character mode) cannot be placed at positions of 12 areas corresponding to each 12 hours within the screen border, as shown in FIG. 5. As described above, 12 touch keys are placed at positions in each of the 12 areas, but each touch key has 12 representative characters and a sequence number adjacent to each of the 12 representative characters, or two or more related characters can be assigned, respectively. have.

As an example, (a) of FIG. 5 shows an IME in the Hangul mode, in which Hangul touch keys are arranged at 12 locations corresponding to each 12 hours within the screen border, and each Hangul touch key is statistically frequent. Consonants and vowels used are assigned as representative letters, and the remaining keys are assigned together with at least one representative letter.

At this time, the text mode conversion touch key 210 is included in the IME, and the controller 180 is shown in FIGS. 5B and 5C whenever the text mode conversion touch key 210 is selected. As described above, the IME in the Korean mode is converted to an IME in the numeric mode and the IME in the English mode and displayed.

Next, as shown in FIG. 6, when a specific content is displayed in the circular screen and the IME is displayed within the screen border, the controller 180 displays the screen with the screen minimally covered. By doing so, it is possible to allow the user to input a desired character through the IME while the screen is at least covered, and when the result of the screen changes according to the input character, the character can be input while viewing the screen.

In this case, the controller 180 may display the IME by translucent processing on the border of the screen so that the IME covers the screen to the minimum. In addition, the IME is usually hidden on the screen and then displayed on the screen. The IME can also be displayed when the border is touched.

As shown in (a) of FIG. 6, a list including specific items is displayed on the screen, and when a specific touch key in the IME displayed on the screen border is selected, the control unit 180 selects the items in the list. Items including characters assigned to the selected touch key may be changed and displayed.

Next, as shown in (b) of FIG. 6, a web page providing a specific search box is displayed in the screen, and the controller 180 when a specific touch key in the IME displayed on the screen border is selected. , A character assigned to the selected touch key may be input as a search word in the search window, and a web page in which a search result according to the search word is reflected may be displayed.

Next, as shown in (c) of FIG. 6, a phonebook is displayed in the screen, and when a specific touch key in the IME displayed on the screen border is selected, the selected You can search for and display contacts including letters assigned to touch keys.

Next, FIG. 7 shows an example of a text input method using the IME.

That is, as shown in (a) of FIG. 7, when the first touch key 220 is touched in the IME of a specific character input mode and then released at the position of the first touch key 220 , A representative character ("Q") 221 assigned to the first touch key 220 is automatically written in the character input window.

At this time, the controller 180 is a representative character ("Q") 221 assigned to the first touch key 220 within the first touch key 220 until the first touch key 220 is touched and released. You can also display only.

Meanwhile, when the first touch key 220 is touched and then dragged and released from the position of the second touch key, the controller 180 may automatically write a representative character assigned to the second touch key.

Next, as shown in (b) of FIG. 7, when the first touch key 220 is touched and then dragged in the first direction (left direction) and then released, the first touch key 220 A character (“R”) 222, which is assigned to 220 together with a representative character (“Q”) and displayed in the first direction based on the representative character (“Q”), is automatically written in the character input window.

At this time, the controller 180 controls the letter ("R") within the first touch key 220 and within the first touch key 220 until the first touch key 220 is touched and dragged in the first direction and then released. ") It is also possible to display only 222.

Next, as shown in (c) of FIG. 7, after the first touch key 220 is touched, the controller 180 is dragged in a second direction opposite to the first direction (right direction), and then released. Then, the character is assigned to the first touch key 220 together with the representative character ("Q"), and the character ("P") 223 displayed in the second direction based on the representative character ("Q") is input. Automatically fill in the window.

At this time, the controller 180 controls the letter ("P") in the first touch key 220 and in the first touch key 220 until the first touch key 220 is touched and dragged in the second direction and then released. ") It is also possible to display only 223.

Next, as illustrated in FIG. 8, when a preset touch key in the IME is touched in a preset manner, the controller 180 may provide a setting menu of the IME to the user.

For example, as shown in (a) of FIG. 8, when the character mode conversion touch key 210 of the touch keys in the IME is long-touched, as shown in (b) of FIG. , The IME setting menu 320 is displayed.

As an example, the setting menu 320 indicates that it includes a first menu for setting the type of language of the IME, a second menu for changing the template of the IME, and a third menu for setting whether or not to use recommended words. have.

In addition, the setting menu 320 may further include a fourth menu for adjusting the width of the IME at the border of the screen.

That is, as shown in (a) of FIG. 9, when the fourth menu is selected, the controller 180 activates the width adjustment mode of the IME, and the user selects the boundary line 200A of the IME in the width adjustment mode. ) Can be dragged to adjust the width.

That is, the controller 180 increases the width of the IME as the border line 200A is dragged toward the center of the circular screen, and increases the width of the IME as the border line 200A is dragged outside the circular screen. It is to narrow it down.

In this case, the controller 180 increases the font size of the characters allocated to the touch keys in proportion to the extent to which the width of the IME is widened, and increases the font size of the characters allocated to the touch keys in proportion to the extent to which the width of the IME is narrowed. You can reduce the font size.

When the width adjustment of the IME is completed, as shown in (b) of FIG. 9, when a preset type of touch gesture is input on the screen, the controller 180 deactivates the width adjustment mode of the IME. For example, the touch gesture may be a double touch in which a specific point on the screen is continuously touched twice.

Next, as shown in FIG. 10, while the IME and the specific text sentence are displayed on the screen, the controller 180 gradually automatically automatically selects the characters in the text sentence according to the touch wheel operation of the IME. You can choose.

That is, conventionally, in order to edit a desired part within a text sentence (copy, cut, share, etc.), the desired part must be designated by dragging it, but on a small screen such as a smart watch, the desired part is touched and It is not easy to specify by dragging.

Accordingly, in the present invention, the IME displayed on the circular screen border can be used together with a touch wheel to designate a desired portion within the text character.

For example, as shown in (a) of FIG. 10, when a specific point of a text sentence displayed in the screen is long-touched, the controller 180 activates the touch wheel operation mode of the IME, and (b) of FIG. As shown in ), when a clockwise or counterclockwise drag touch is input on the IME, characters in the text sentence may be gradually and automatically designated according to the drag distance of the drag touch.

As an example, the long-touched part of the text sentence becomes a starting point to be designated by the user, and the controller 180 gradually automatically designates one character at a time as the drag touch gradually progresses from the starting point.

Next, FIG. 11 shows a touch key recognition process and a touch key error correction process using a polar coordinate system.

That is, referring to FIG. 11, a touch coordinate based on a center point is converted into a polar coordinate system using equations of y = rsinθ and x = rcosθ, and a touch key touched by a user is recognized according to r and θ.

For example, when recognizing a touch key to which N letters are assigned in the IME, r is greater than an inner radius of an area in which the N letter assigned touch key is located, and θ is greater than 15° and less than 45°.

In addition, in the case of a circular watch-like appearance such as the smart watch of the present invention, the upper exterior portion is not easily touched due to the bezel.

The reason is that when the user touches the touch key of the lower part, it is possible to touch with the finger raised, but when the touch key of the upper part of the center or above is touched, the surface of the finger is touched, making accurate touch difficult.

In conclusion, since the probability of occurrence of a touch error on the upper part of the screen is high, in the present invention, the touch coordinates are converted to polar coordinates based on the center point of the screen, and the touch to the specific touch key touched in the IME according to θ. It greatly corrects the r value of. That is, the correction area is enlarged toward the upper area of the screen.
