Description

TECHNICAL FIELD [0001] The present invention relates to a keyboard input system and method for a small smart device, and a computer readable recording medium storing a program for executing the same.

The present invention relates to a keyboard input system and method for a device having a touch screen, and more particularly, to a keyboard input system and method for efficiently inputting keyboard input on a device having a touch screen of a limited size such as a wearable device such as a smart clock, And more particularly, to a keyboard input system and method for performing a keyboard operation.

Generally, thanks to the development of IT technology, various input methods of Hangul are developed and they are implemented in various forms. The first button-type input method would input Hangul in a way that it displayed one or more consonants and vowels on the keyboard and changed into different consonants and vowels through the use of a single click or double click.

In this way, the input method is changed by the development of the touch panel. Nowadays, the method of inputting characters is seeking a new alternative aiming at high quality convenience.

In recent years, researches and interest in wearable devices have become more and more popular as Samsung Electronics and other international IT companies such as Apple and Google have launched smart watches.

As such, in recent years, research on smart clocks has been actively carried out, and complicated functions such as character and phone identification, which were possible in existing smart phones, are gradually becoming feasible. However, the smart clock provides a very small size input device compared to the conventional touch screen provided by the existing smartphone, so that when the conventional QWERTY keyboard is applied as it is, it is very inefficient because proper input is not performed.

Therefore, it is required to study efficient keyboard input with high accuracy and fast input by providing a low error rate, high intuitiveness and typing speed on a touch screen of limited size.

1 is a block diagram illustrating a configuration of a keyboard input system for a small smart device according to an embodiment of the present invention.

As shown in FIG. 1, the keyboard input system of the present invention includes a key setting unit 100, a touch signal input unit 200, and a character determination unit 300.

At this time, the key setting unit 100 sets up four key regions, configures a character set for each input key, and then outputs each character to an appropriate position of the key region based on the sweep trajectory of the user do. The reason for constructing a character set for each key is to connect one or more characters to one key because the number of characters to input is larger than the number of keys to be used for input.

That is, as shown in FIG. 2A, the key setting unit 100 divides the key area into four zones, and displays one input main character in each zone. In addition, at least two sub characters consisting of one set of three different characters are defined and displayed around the main character of each divided area. At this time, the character size of the sub character is displayed smaller than the character size of the main character.

After one of the regions where the main character is displayed is selected and then swiped in the direction of the sub character displayed together with the selected main character, as shown in FIG. 2B or FIG. 2C, The main character is deleted in each of the key areas, and the position is displayed such that the sub characters that can be input are positioned one by one. At this time, one sub-character is displayed in one of the four regions of the key region and one of the sub-characters is displayed in the other region, and the "previous" symbol for returning to the previous position is displayed.

On the other hand, the characters (main character, sub character) positioned in the key area divided into the four zones are selected by the double click or the release of the touch.

The touch signal input unit 200 detects a touch state and a moving trace after touching based on a signal input by a user using a finger or an electronic pen on a touch screen or the like and transmits the touch signal to the key setting unit 100 and the character determination unit 300 ), And so on.

The character determination unit 300 further includes a touch start key detection unit 310 that detects a touch start position based on a touch state and movement trajectory transmitted through the touch signal input unit 200, A touch trajectory analysis unit 320 for analyzing a movement trajectory through a moving direction and a distance in a touched state based on the detected position detected by the touch start key detection unit 310; And an input character determination unit 330 for determining a character to be finally input in accordance with the direction of movement in the moved locus, the direction of the point, and the like.

The operation of the keyboard input system for the small smart device according to the present invention will now be described in detail with reference to the accompanying drawings. 1 to 3 denote the same members performing the same function.

4 is a flowchart illustrating a keyboard input method for a small smart device according to an embodiment of the present invention.

4, first, the touch screen of the smart device is divided into four key areas with the same size through the key setting part 200, coordinate values are set for each divided key area, and different character sets (S100).

At this time, the character set is displayed by placing one main character that can be input in each divided key region in the center and arranging at least two sub characters composed of one set of three different characters around the main character Display. At this time, the character size of the sub character is displayed smaller than the character size of the main character. The coordinate values for each key region are divided into four key regions having the same size, so that when the size of the screen is n, the upper left corner (hereinafter referred to as " (Hereinafter referred to as " zone 2 ") is defined as (0, 0), the coordinates of the lower left (0, n / 2), and the coordinates on the lower right (n / 2, n / 2) / 2).

If the user detects coordinates of a touched area based on a signal input by a user using a finger or an electronic pen on a touch screen or the like through the touch signal input unit 200 and transmits the coordinates to the character determination unit 300, The controller 300 detects the first key region that is touched based on the coordinates of the touched region transmitted from the touch signal input unit 200 through the touch start key detection unit 310 at step S200.

5, the touch start key detection unit 310 of the character determination unit 300 receives the x and y coordinates of the touched area through the touch signal input unit 200 (S210) And detects a touched key region based on coordinate values set for each key region divided through the key setting unit 200. [ That is, when the transmitted coordinates are 0 <x <n / 2 and 0 <y <n / 2 (S220), zone 1 is detected (S230). If the coordinate is n / 2 < x < n and 0 < y < n / 2 (S240), zone 2 is detected (S250). If the coordinates are 0 <x <n / 2 and n / 2 <y <n (S260), Zone 3 is detected (S270) .

Then, the character determination unit 300 determines the direction of movement of the touched area based on the coordinates of the touched area transmitted from the touch signal input unit 200 through the touch trajectory analysis unit 320 The moving trajectory is analyzed through a distance or the like (S300).

6, the touch trajectory analysis unit 320 of the character determination unit 300 continuously receives the x and y coordinates of the region 1 (S310) In the case where the coordinate transferred from the zone 1 is n / 2 < x < n (S320), the movement trajectory in the right direction of the zone 1 is selected (S330). If the transmitted coordinate is n / 2 < y < n (S340), the movement trajectory in the downward direction of the zone 1 is selected (S350). On the other hand, if an additional movement trajectory is not selected after Zone 1 is selected, the character A set in Zone 1 is directly selected (S700).

When the movement trajectory is analyzed through the character determination unit 300 and the movement trajectory is selected (S400), the key setting unit 100 checks whether the sub character exists at the moved position according to the analyzed movement trajectory (S500 ).

As a result of the check (S500), when the sub-character is confirmed, the key setting unit 100 sets three different characters of the verified sub-character as a key area divided into four zones as shown in FIG. 2B or 2C, The main characters are deleted from the main characters, and the positions are displayed one by one in such a form that sub characters can be input (S600). At this time, one sub-character is displayed in one of the four regions of the key region and one of the sub-characters is displayed in the other region, and the "previous" symbol for returning to the previous position is displayed.

Then, while repeating the moving trajectory analyzing process (S300), the character determining unit 300 finally inputs the moving character trajectory to the analyzed moving trajectory through the input character deciding unit 330 according to the moving direction or the direction of the starting point Character is determined (S700).

As one example, the case where the touch screen coordinates move in the right direction of the region 1 will be described in more detail with reference to FIG. 7. As shown in FIG. 2B, The character trajectory analyzing unit 320 of the input character determining unit 330 analyzes the analyzed moving trajectory to display the touch character in the key region. (Step S611).

At this time, if the last coordinates to be input are 0 <x <n / 2 and 0 <y <n / 2 (S612), a 'return' value is finally selected as a character to be input (S613). If the last coordinate input is n / 2 <x <n and 0 <y <n / 2 (S614), the value of 'B' is finally selected as the character to be input (S615). If the input final coordinate is 0 <x <n / 2 and n / 2 <y <n (S616), the value of 'C' is finally selected as the character to be input (S617). If the last coordinate input is other than 'D', the character to be finally input is selected (S618). FIG. 9 is a diagram showing a touch screen screen when 'D' is selected through this method.

As another example, the case where the touch screen coordinates move in the right direction of the zone 1 will be described in more detail with reference to FIG. 8. As shown in FIG. 2C, After the sub character (E, F, G) is positioned and displayed in the divided key area, the analysis of the analyzed movement trajectory through the touch trajectory analysis unit 320 of the input character determination unit 330 determines The x and y coordinates are input (S621).

At this time, if the last coordinates to be input are 0 <x <n / 2 and 0 <y <n / 2 (S622), the 'return' value is finally selected as the character to be input (S623). If the last coordinate input is n / 2 < x < n and 0 < y < n / 2 (S624), the 'G' value is finally selected as the input character (S625). If the last coordinate input is 0 <x <n / 2 and n / 2 <y <n (S626), the value of 'F' is finally selected as the character to be input (S627). If the input coordinate is other than the last coordinate, 'E' is selected as the character to be finally input (S628).

Meanwhile, the embodiment of the present invention can be made into a program that can be executed in a computer. That is, the various steps involved in the method according to the present invention may be stored in a computer readable recording medium. The medium may be a magnetic storage medium such as a ROM, a floppy disk, a hard disk, etc., an optical reading medium such as CD-ROM or DVD, a digital storage medium such as a USB memory, XD), etc.) and carrier waves (e.g., transmission over the Internet).

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. It will be apparent to those skilled in the art that various modifications may be made without departing from the scope of the present invention.
