In addition, the terms "... unit", "... unit", "module", "block", etc. described in the specification mean a unit for processing at least one function or operation, which means hardware, software, or hardware. And software.

Now, a keyboard system and an operation method thereof according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

First, a keyboard system according to an exemplary embodiment of the present invention will be described with reference to FIG. 1.

1 is a block diagram illustrating in detail a keyboard system according to an exemplary embodiment of the present invention.

As shown in FIG. 1, a keyboard system 400 according to an exemplary embodiment of the present disclosure includes an input unit 100, a control unit 200, and a display unit 300.

The input unit 100 includes a first input module 110 having a touch pad function and a second input module 120 having a touch button function.

The first input module 110 performs a touch pad function, and provides the controller 200 with movement information received according to a movement of a user's finger on the touch pad. The motion information includes a time sequence of contact point position information of the user on the touch pad.

Here, the input area of the first input module 110 is divided into a plurality of virtual zones 112 in a lattice manner, each of which can be taken by the selection area 312 on the virtual keyboard 310. Matches the position. For example, if the virtual keyboard 310 has a plurality of 6 * 10 grid cells and the selection area 312 is 2 * 2 size, the first input module 110 is a 3 * 5 size area. Has 112. At this time, the selection area 312 moves in correspondence with the contact point position of the user's finger received from the first input module 110, and inputs using the second input module 120 among the cells 311 of the virtual keyboard. Indicates the current selection range. In addition, the selection area is provided to the user as a separate display process so that the user can distinguish it from the rest of the virtual keyboard.

The second input module 120 is a touch button combined with a touch pad function and a button, and includes a first input region 122, a second input region 124, and a third input region 126.

For example, when the selection area of the virtual keyboard 310 includes 2 * 2 grid cells 311, the first input area 122 will include 2 * 2 grid areas.

 Here, when the user presses the touch button while the user's finger is in contact with the grid area of (R, C) (column R, column C) of the first input area 122, the key of the (R, C) cell of the selected area is pressed. Is entered.

The second input zone 124 is a zone for changing the keyboard. When the user presses a touch button in this zone, the controller 200 processes the keyboard change of the virtual keyboard.

The third input zone 126 is a zone for changing the mouse mode, and when the user presses a touch button in this zone, the controller 200 processes the change of the mouse mode.

The input unit 100 separates the pointing function and the button function into the first input module (or first input unit) 110 and the second input module (or second input unit) 120, thereby making a very small size (eg, For example, even if the system is implemented with a touch pad and a touch button having a height of 1 cm and a width of 1.5 cm, there is a big advantage that the user can stably input keys.

In addition, by introducing a moving selection area in the virtual keyboard to reduce the over-density of the grid cells on the touch pad, there is an advantage that can improve the stability for the user pointing.

In addition, the actual input in the virtual keyboard system of the present invention is made through a touch button of a larger size than the grid cell of the touch pad, so that the negative accuracy and the surrounding cell area of the button press that can occur when pressing the touch pad directly There is an advantage that can avoid interference with the noise, such as noise.

In particular, by changing the size of the selection area 312 on the virtual keyboard 310 to efficiently increase or decrease the number of zones 112 included in the first input module 110, so that the user can correct the key input. Allows pointing, and effectively increases or decreases the number of button cells in the first input area 122 included by the second input module 120 by changing the number of grid cells included in the selection area on the virtual keyboard. By doing so, it is possible to simultaneously input a plurality of keys and minimize interference with peripheral keys.

The controller 200 includes a control module 210 and a memory 220, controls the virtual keyboard based on user input information (motion information and press information) received from the input unit 100, and outputs the control. Provide information to the upper level (omitted).

The memory 220 is controlled by the control module 210 and stores a plurality of pre-stored virtual keyboard keyboard contents as a library for searching.

The control module 210 controls and manages the memory 220, the input unit 100, and the display unit 300, and specifically, the virtual keyboard 310 based on the user's movement information received from the first input module 110. ) Moves the selection area 312 on () or changes the keyboards 310-1, 310-2, 310-3, and 310-n of the virtual keyboard 310.

In addition, the control module 210 receives the user's press information from the first input area 122 of the second input module 120 to input the first input in the current selection area 312 of the virtual keyboard 310. Provides a letter or symbol of the grid cell 311 that matches the user contact point of the area 122 to the upper level, and provides a keyboard change mode based on the second press information from the second input area 124. do.

When the second press information for changing the keyboard is generated, the control module 210 reverses the current keyboard mode changing state. When the switched state is active and subsequent user movement occurs in the first input module, a keyboard change is performed from the keyboard library of the memory 220 based on that, and the user movement occurs in the first input region of the second input module. Based on this, a keyboard change is performed from the recent keyboard list of the memory 220.

In addition, the control module 210 sets (activates or deactivates) the mouse function based on the user's press information received from the third input area 126.

Here, when the mouse mode is activated, the control module 210 performs a mouse pointing function based on the first movement information of the user received from the first input module 110, and the first input of the second input module 120. The first press information of the user received from the zone 122 is used as the mouse click information.

The display unit 300 displays the virtual keyboard 310 in some screen areas, and the keyboards 310-1, 310-2, 310-3, 310-n selected by the user based on the control of the controller 200 are displayed.
