In the setting mode, as shown in FIG. 7, when the specific key buttons 220 and 230 are dragged to the left or the right direction, as shown in FIG. 8. Likewise, the virtual keyboard 210 is moved to the left side or the right side of the display unit 151. Similarly, when the specific key buttons 220 and 230 are dragged upward or downward, the virtual keyboard 210 is moved upward or downward of the display unit 151.

As shown in FIG. 9, when the specific key buttons 220 and 230 are dragged in the rotating direction, the angle of the virtual key button 210 may be changed or various results may be obtained by rotating the specific key button.

10 and 11, in the setting mode, the selected key button 250 may be operated to increase or decrease the size of only the selected key button 250. For example, when the selected key button 250 is dragged in one direction, the size increases, and when the selected key button 250 is dragged in the other direction, the size decreases.

When a user manipulates a virtual key button, a key button that frequently generates a typo exists. The key button frequently generates a typo using a backspace key button. If it is identified, it is possible to reduce the typo by increasing the size of the key button, which frequently generates typos.

12 and 13, when a typo is frequently detected due to interference of two key buttons among key buttons frequently occurring on a typo, the interval between the two key buttons is widened.

That is, as shown in FIG. 12, when the two selected key buttons 260 and 270 are simultaneously drawn outward in the setting mode, the distance between the two selected key buttons 260 and 270 may be widened as shown in FIG. 13. To help.

In addition, if the key button is used a lot, the material may be set to be worn, crushed, or stained with the hand, and a material effect such as wood or metal may be used to induce a user's interest.

Although embodiments according to the present invention have been described above, these are merely exemplary, and it will be understood by those skilled in the art that various modifications and equivalent embodiments of the present invention are possible therefrom. Therefore, the true technical protection scope of the present invention will be defined by the following claims.

200: body 151: display unit
210: virtual key button 220, 230: specific key button
240: remaining area
