DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings and embodiments. However, the drawings and the embodiments are only illustrative of the contents and scope of the technical idea of the present invention, and the technical scope of the present invention is not limited or changed. It will be apparent to those skilled in the art that various changes and modifications can be made within the scope of the technical idea of the present invention based on these examples.

A configuration of a portable terminal to which the present invention is applied and a keyboard adjustment method using the same will be described with reference to FIG.

In the present invention, the portable terminal includes a touch screen 11 and includes a sensor unit 12, a finger information generating unit 13, and a keyboard size adjusting unit 14. The sensor unit, the finger information generating unit, and the keyboard size adjusting unit are named by distinguishing functions of sensors and operation processes of the touch screen. Since the smart phone and the smart device which are typical portable terminals include the touch screen 11 and can operate, a personalized keyboard can be provided by applying the keyboard adjustment method of the present invention by a simple program without any additional device .

The touch screen 11 receives touch information from a user and sends the touch information to the sensor unit 12.

The sensor unit 12 senses the user's touch and sends it to the finger information generating unit 13. [

The finger information generating unit 13 generates various information about the user's finger.

The keyboard size adjustment unit 14 adjusts the size of the keyboard based on the finger information.

Figure 2 illustrates a customized input element shown on the screen for collecting finger size data of a user. When the keyboard is first implemented, the customized input element 110 is displayed on the screen to collect the user's finger data. Customizable input elements can use the QWERTY keyboard used in typical smartphones and smart devices, and other keyboard types can be used. When the user's touch 200 is input to the customized input element, the sensor unit 12 recognizes the finger contact area of the user. The portable terminal 100 including the touch screen may provide a customized input element 110 for each user through the above process.

<Finger Information Generation Method>

Hereinafter, a method of generating information on a finger in the finger information generating unit will be described in detail with reference to FIG.

The user inputs a finger size by touching the finger to the touch screen 11, receives the input coordinates from the sensor unit 12, and calculates the horizontal length and the vertical length of the finger size input to calculate the distance between the input coordinates .

The finger information generating unit 13 compares the finger contact area of the user with the average size reference on the basis of the preset finger average size, and generates finger size data.

<Keyboard Adjustment Method of Portable Terminal>

A keyboard adjusting method of a portable terminal according to the present invention will be described with reference to FIG.

3 is a diagram showing an embodiment of a keyboard change according to the present invention. After the user's touch 200, the sensor unit 12 recognizes the finger contact area of the user and detects the distance between the maximum horizontal length and the vertical maximum length between the input coordinates according to the contact area (210). At this time, the finger information generating unit 13 compares the preset finger average size with the detected finger contact area of the user, and generates finger information of the user. Based on the generated finger information, the keyboard size adjusting unit 14 adjusts the size and the interval of the keyboard to be optimized to the user's finger size (220). In some cases, a certain number of typos may occur particularly when a particular character is input. In order to reduce the inconvenience, it is more desirable to adjust the size and spacing of the key of the specific character as well as adjust the entire keyboard spacing according to the size of the finger in a lump.

Alternatively, the user may be provided with a screen for controlling the interval of the keyboard, and each of the keys may be touched at least once, and then the horizontal and vertical contact areas of the finger may be calculated according to the positions of the keys, More preferable. In this case, a key having a small contact area of a finger is relatively small, a space is narrowed, a key having a large contact area of a finger and a high possibility of a typo is relatively large, have. For more accurate measurements, you can touch each key several times and use the average value. If the error of each touch on the same key is large even when repeatedly touching, the number of touches can be increased individually.

FIG. 4 is a diagram illustrating an example of a screen in which a size and an interval of a keyboard are adjusted through a slide. 4, when the user inputs a size and an interval of the user's keyboard in the manual adjustment mode 310, the user can use the slide button 300 to select the key of the keyboard And the interval between the keys can be reset. In this case, the user can adjust the size of the keyboard using the slide button. For example, when the user slides to the right, the interval of the keyboard becomes narrower, the size of the keyboard becomes larger, Becomes smaller.

4 (a) is a keyboard in which the size and spacing of keys are reduced, and when the upper slide button 300 is moved to the right, a state in which the size and spacing of the keys of the keyboard are maximized is shown as (b ). Here, it is assumed that the state where there is no space between the keys as shown in FIG. 4 (b) is that the size of the key of the keyboard is maximized.

<Method for Adjusting Keyboard Transparency of Portable Terminal>

In the present invention, the transparency of the keyboard can also be adjusted. 5 is a diagram illustrating a screen in which keyboard transparency is adjusted through a slide. The user can set the transparency of the keyboard using the slide button 400 in order to efficiently use the limited space screen with the keyboard through the manual mode 310 of the keyboard. For example, when the user slides to the right, the transparency of the keyboard increases and the screen utilization also increases (FIG. 5 (b)), the transparency of the keyboard decreases when sliding to the left, and the keyboard is displayed clearly (FIG.

&Lt; Method of Adjusting Keyboard One-Hand Mode of Portable Terminal >

The keyboard adjustment method of the present invention can be applied to the one-handed mode as well as the two-handed mode.

In the present invention, when the portable terminal is used with one hand, it is possible to provide a one-handed mode keyboard that is easy to use. 6 is a diagram illustrating a screen in the case where the user selects the keyboard size one-hand adjustment mode in the manual adjustment mode. The user sets one of the left-handed mode 500-1 displayed at the lower left of the screen and the right-handed mode 500-2 displayed at the lower right of the screen through the keyboard manual control mode 310, The one-hand adjustment mode 500 is a mode in which the top of the keyboard is displayed in a round shape within a range of a thumb of a user who has made contact with the terminal. The keyboard size one-hand adjustment mode 500 reduces the key size to a predetermined ratio to enter the one-hand adjustment mode keyboard.

The size and spacing of each key can be adjusted in the same way as in the two-handed mode, so a detailed description thereof will be omitted.

&Lt; Finger standard and average size of the portable terminal >

In the present invention, in order to change the key of the keypad and its interval to fit the contact area of the user's finger, the user's fingertip contact area is input through the sensor unit, and the reference inherent in the terminal is changed. For example, the criteria embedded in the terminal is based on the finger average size, which can be specified as 0.4 cm / 0.5 cm in width. However, it is a matter of course that the above numerical values can be appropriately set to arbitrary ones.
