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 of an object approaching a predetermined detection surface or an object existing in the vicinity of the detection surface without mechanical contact using an electromagnetic force or infrared rays. The proximity sensor 141 may be disposed in the inner area of the mobile terminal or in proximity to the touch screen, which is covered by the touch screen. The proximity sensor 141 has a longer life than the contact type sensor and its utilization is also high.

Examples of the proximity sensor 141 include a transmission type photoelectric sensor, a direct reflection type photoelectric sensor, a mirror reflection type photoelectric sensor, a high frequency oscillation type proximity sensor, a capacitive proximity sensor, a magnetic proximity sensor, and an infrared proximity sensor. In the case where the touch screen is electrostatic, the proximity sensor 141 can be configured to detect the proximity of the object with a change of the electric field along the proximity of the object having conductivity. 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 act of recognizing that the object is located on the touch screen in proximity with no object touching the touch screen is referred to as "proximity touch & The act of actually touching an object on the screen is called a "contact touch. &Quot; The position at which the object is closely touched on the touch screen means a position where the object corresponds to the touch screen vertically when the object is touched. The proximity sensor 141 can detect a proximity touch and a proximity touch pattern (e.g., a proximity touch distance, a proximity touch direction, a proximity touch speed, a proximity touch time, a proximity touch position, have. Meanwhile, the control unit 180 processes data (or information) corresponding to the proximity touch operation and the proximity touch pattern sensed through the proximity sensor 141 as described above, and further provides visual information corresponding to the processed data It can be output on the touch screen. Furthermore, the control unit 180 can control the mobile terminal 100 such that different operations or data (or information) are processed according to whether the touch to the same point on the touch screen is a proximity touch or a touch touch .

The touch sensor senses a touch (or touch input) applied to the touch screen (or the display unit 151) by using at least one of various touch methods such as a resistance film type, a capacitive type, an infrared type, an ultrasonic type, do.

The touch sensor may be configured to detect a position, an area, a pressure at the time of touch, etc. of a touch object to be touched on the touch screen on the touch sensor. Here, the touch object may be a finger, a touch pen, a stylus pen, a pointer, or the like as an object to which a touch is applied to the touch sensor.

Thus, when there is a touch input to the touch sensor, the corresponding signal (s) is sent to the touch controller. The touch controller processes the signal (s) and transmits the corresponding data to the controller 180. Thus, the control unit 180 can know which area of the display unit 151 is touched or the like. Here, the touch controller may be a separate component from the control unit 180, and may be the control unit 180 itself.

On the other hand, the control unit 180 may perform different controls or perform the same control according to the type of the touch object, which touches the touch screen (or a touch key provided on the touch screen). Whether to perform different controls or to perform the same control according to the type of the touch object may be determined according to the current state of the mobile terminal 100 or an application program being executed.

Touch can be sensed.

The ultrasonic sensor can recognize the position information of the object to be sensed by using ultrasonic waves. On the other hand, the controller 180 can calculate the position of the wave generating source through the information sensed by the optical sensor and the plurality of ultrasonic sensors. The position of the wave source can be calculated using the fact that the light is much faster than the ultrasonic wave, that is, the time when the light reaches the optical sensor is much faster than the time the ultrasonic wave reaches the ultrasonic sensor. More specifically, the position of the wave generating source can be calculated using the time difference with the time when the ultrasonic wave reaches the reference signal.

The camera 121 includes at least one of a camera 121, a photosensor, and a laser sensor. The camera 121 is a kind of camera sensor.

The photosensor can be laminated to the display element, which is adapted to scan the movement of the object to be detected proximate to the touch screen. More specifically, the photosensor mounts photo diodes and TRs (Transistors) in a row / column and scans the contents loaded on the photosensor using an electrical signal that varies according to the amount of light applied to the photo diode. That is, the photo sensor performs coordinate calculation of the object to be sensed according to the amount of change of light, and position information of the object to be sensed can be obtained through the calculation.

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

8 (a), when the text mode conversion touch key 210 among the touch keys in the IME is long-touched, as shown in (b) of FIG. 8, , And displays the setting menu 320 of the IME.

For example, the setting menu 320 includes a first menu for setting the language type of the IME, a second menu for changing the template of the IME, and a third menu for setting whether or not to use the recommended word have.

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

9A, when the fourth menu is selected, the controller 180 activates the width adjustment mode of the IME, and the user selects the width of the IME boundary 200A ) Can be dragged to adjust the width.

That is, the control unit 180 increases the width of the IME as the boundary line 200A is dragged toward the center of the circular screen, and increases the width of the IME as the boundary line 200A is dragged out of the circular screen To narrow it.

At this time, the controller 180 increases the font size of the characters allocated to the touch keys in proportion to the width of the IME, and determines the size of the characters assigned to the touch keys in proportion to the narrowing of the width of the IME You can reduce the font size.

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

10, when the IME and the specific text are displayed on the screen, the controller 180 gradually and automatically processes the characters in the text corresponding to the touch wheel operation of the IME, You can choose.

In other words, conventionally, in order to edit (copy, cut, share, etc.) a desired portion within a text sentence, a desired portion must be dragged and designated in the text sentence. In a small screen such as a smart watch, It is not easy to specify by dragging.

Accordingly, in the present invention, a desired portion can be designated in the text character by using the IME displayed on the circular screen frame as a touch wheel.

10 (a), the controller 180 activates the touch wheel operation mode of the IME when a specific point of a text sent within the screen is long-touched, , When a clockwise or counterclockwise dragging touch is input on the IME, the characters in the text sentence can be gradually designated in accordance with the drag distance of the dragging touch.

For example, in the text sentence, the long-touched portion becomes a start point to be designated by the user, and the control unit 180 gradually specifies one character gradually from the start point as the drag touch progresses gradually.

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, the touch coordinates are converted into a polar coordinate system using the equations of y = r sin θ and x = r cos θ based on the center point, and the touch keys touched by the user are recognized according to r and θ.

For example, when recognizing a touch key to which an N character is assigned in the IME, r is larger than an inner radius of an area where the N key is allocated, and? Is larger than 15 degrees and smaller than 45 degrees.

In addition, in the case of an outer appearance such as a circular watch like the smart watch of the present invention, the touch of the upper outer part is not good due to the bezel.

The reason is that when the user touches the touch key of the lower part, the user can raise the finger by touching the touch key, but when touching the touch key of the upper part above the center, the face of the finger is touched and the accurate touch becomes difficult.

As a result, since the probability of occurrence of a touch error at the upper portion of the screen is large, in the present invention, the touch coordinates are converted into a polar coordinate system based on the center point of the screen, And the r value of the R value. That is, the correction area is made larger toward the upper area of the screen.
