Description

Method for providing an on-screen keyboard and computing device performing the same

The present invention relates to a method for providing an on-screen keyboard and a computing device performing the same.

Various digital mobile devices such as smartphones, tablets, phablets and the like are used. Here, the phablet generally refers to a smartphone having a large screen of 5 inches or more, and is a compound word of a phone and a tablet. Such digital mobile devices have a touch-sensitive display and provide an on-screen keyboard as an interface for user input. The user can enter data using the on-screen keyboard. As the mobile phone market is being reorganized by smartphones, the popularity of smartphones with large screens has been increasing since 2010. The development of display technologies such as liquid crystal displays (LCDs) and organic light emitting diodes (OLEDs) is also contributing to the enlargement of screens of digital mobile devices.

Recently, notebooks with touch-sensitive displays have been released. In some of these notebooks, a physical keyboard for user input is not provided in combination with the main body and is sold separately. In other words, laptop keyboards are sold as peripherals. These notebooks provide an on-screen keyboard as an interface for user input. The notebook user may input data by touching an object such as his finger or a stylus pen on the touch-sensitive display without using a keyboard. In general, laptops are manufactured with large screens that are 14 inches or 15 inches in size.

On the other hand, in the case of a typical smartphone, the user types using only the thumb (while supporting the smartphone with the remaining fingers) while holding the smartphone with one hand or both hands. The only difference is that the smartphone is held vertically or horizontally, and most users type using only their thumb while holding the smartphone. However, in the case of a tablet, a tablet, a notebook, etc. having a relatively large screen size, it is difficult to lift it with one hand due to its weight. In addition, even if the user lifts these devices with both hands, it is very inconvenient to type using only the thumb because the screen is large (and therefore, the size of one key on the on-screen keyboard and the spacing between the keys). . Due to this inconvenience, for those devices with relatively large screen sizes, the user prefers to type the device down on a table or floor.

However, these devices provide an on-screen keyboard in the form of a qwerty keyboard, which is mostly used as a standard. According to the fingering of the QWERTY keyboard, the use of both hands is essential, so it is very difficult for the user to type with only one hand. Alternatively, these devices convert only the physical keyboard that was previously available in the feature book (before smartphone launch) into an on-screen keyboard. Since such keyboards are not optimized for touch-sensitive displays, key input is slow and inconvenient.

"On-screen keyboard" means a keyboard that is provided virtually (non-physically) on the screen. In the present specification, an "on-screen keyboard" may be simply referred to as a "keyboard", and both may be used interchangeably.

The on-screen keyboard is provided by a computing device that includes a touch-sensitive surface and a display device. In some embodiments, the touch sensitive surface may be disposed on the surface of the computing device along the housing of the computing device. The touch sensitive surface comprises one or more touch sensors. The touch sensor detects contact or proximity of an object such as a user's finger or a stylus pen. In some embodiments, the touch sensitive surface may include a cover or film to protect the touch sensor. In some embodiments, the touch sensor may be provided as a capacitive sensor. The touch sensing surface defines a predetermined coordinate system, and specifies a sensing position (a predetermined coordinate or a range of coordinates on the coordinate system) of the object according to the sensing result of the touch sensor. In some embodiments, a single touch-sensitive display may be provided in which the touch sensitive surface and the display device are combined.

A "character" includes all characters that can be input by typing a keyboard, such as a character language such as Korean, alphabet, and Chinese characters, numbers, symbols, and figures.

(S120), determining a predetermined key input intended by the user based on the detection result (S130), and performing a process corresponding to the determined predetermined key input (S140).

In operation S120, the touch by the user may be input by a predetermined type of gesture as described below. The computing device may specify a location at which a touch by the user is input.

In operation S130, the key input intended by the user is not determined only by the position where the touch by the user is input, but is determined by further considering the type of the touch as described below.

In operation S140, the computing device may perform, for example, a character input, a predetermined function of a keyboard, a change in a setting or a state, etc. in response to the determined predetermined key input, but is not limited thereto.

Referring to FIG. 2, a keyboard is provided on a touch sensitive display of computing device 300. In general, the keyboard may be located below the touch-sensitive display. However, the present invention is not limited thereto, and the user may change the position of the keyboard up, down, left, or right as described below.

Referring to FIG. 3, the keyboard 200 is divided into a plurality of areas corresponding to each finger of one hand of a user. In detail, the keyboard 200 includes a first area, a second area, a third area, and a fourth area.

The first area is an area that is generally disposed on the left side of the keyboard 200, the second area is an area that is disposed adjacent to the right side of the first area, and the third area is adjacent to the right side of the second area and the keyboard 200 as a whole. ) Is an area disposed on the right side. The first area corresponds to the first finger of the user, the second area corresponds to the second finger and the third finger of the user, and the third area corresponds to the fourth finger of the user. For example, when the user uses his right hand, the first area corresponds to the user's index finger, the second area corresponds to the user's middle finger and ring finger, and the third area corresponds to the user's possession. When the user uses his left hand, the first area corresponds to the possession of the user, the second area corresponds to the user's ringing and middle finger, and the third area corresponds to the user's index finger. Here, the fact that a predetermined area corresponds to a predetermined finger of the user means that a fingering method using a corresponding finger for touch input to the corresponding area is recommended.

The fourth area is an area which is disposed outside of the keyboard 200 as a whole. For example, as shown in FIG. 3, the fourth region may be disposed adjacent to the right side of the third region, or may be disposed adjacent to the left side of the first region. In addition, the fourth region may be disposed above or below the first region, the second region, or the third region. Meanwhile, the fourth area may be touch input by an arbitrary finger desired by the user. As will be described later, the fourth area is because keys for setting or changing the state of the keyboard 200 are arranged, not for inputting a character or executing a predetermined function of the keyboard 200. That is, not for typing itself.

Although not clearly illustrated, the guide may be displayed at a position corresponding to the thumb when the user uses the right hand or at a position corresponding to the thumb when the user uses the left hand. For example, a guide may be displayed below the first area or below the third area, but is not limited thereto.

Referring to FIG. 4, each of the first area, the second area, and the third area of FIG. 3 includes two or more first keys 210 disposed above and one second key 220 disposed below. .

For example, four first keys 210 may be provided as shown in FIG. 4, but are not limited thereto. The first key 210 has a first size and is a key for inputting a character.

The second key 220 has a second size larger than the first size and is a key for executing a predetermined function of the keyboard 200. For example, as shown in FIG. 4, and as shown in FIGS. 6A to 6H described later, the second key 220 includes a tab (TAB) and a space (SPACE). Space), ENTER (new line or complete input), delitte (delete), shift (SHIFT; single case or vowel conversion), English case conversion (A / a), Korean vowel The keys may be used to execute a function such as a keyboard change, a numeric keypad change 123, an arrow keypad change, and the like, but are not limited thereto.

In some embodiments, a plurality of first keys 210 may be provided vertically side by side. Further, in some embodiments, a plurality of first keys 210 may be provided side by side horizontally. Further, in some embodiments, as shown in FIG. 4, a plurality of first keys 210 may be provided side by side vertically and horizontally. Also, in some embodiments, the first key 210 may be greater than or equal in size to the second key 220. In some embodiments, a plurality of second keys 220 may also be provided.

Meanwhile, two or more characters are assigned to one or more first keys 210 of the plurality of first keys 210 of the first area, the second area, and the third area of FIG. 3. For example, as shown in FIG. 4, three letters “y”, “b”, and “n” may be assigned to one first key 210.

In addition, two or more functions are assigned to one or more second keys 220 of the plurality of second keys 220 of the first area, the second area, and the third area of FIG. 3. For example, as illustrated in FIG. 4, three functions of “TAB”, “SPACE”, and “ENTER” may be assigned to one second key 220.

More than one letter or function is assigned to a key because it uses a touch-sensitive display. This is because the touch-sensitive display can input various touch gestures in addition to taps as described below, and thus, a plurality of different key inputs can be processed according to the type of touch on one key. In addition, the space occupancy of the keyboard can also be improved.

Referring to FIG. 5, the fourth region of FIG. 3 includes one or more third keys 230.

For example, three third keys 230 may be provided as shown in FIG. 5, but are not limited thereto. The third key 230 is a key for setting or changing the state of the keyboard 200. Since the third key 230 is not for inputting a character or executing a predetermined function of the keyboard 200, the third key 230 has a size smaller than that of the first key 210 or the second key 220.

For example, as illustrated in FIG. 5, the third key 230 may include a plurality of

keys

231, 232, and 233 for executing a language selection function, a keyboard hiding function, and a keyboard moving function. It is not limited. When the language selection function is executed, the keyboard on which a key board of a predetermined language is arranged is converted from a keyboard on which a key board of a predetermined language is arranged. When the keyboard hiding function is executed, the keyboard is hidden without displaying at least part of it. For example, the remaining areas of the keyboard except for the third key 232 may not be displayed. Or, the entire area of the keyboard may not be displayed. Also, the character input function by the keyboard is not executed. The keyboard movement function will be described later with reference to FIG. 8. In some embodiments, third key 230 may further include keys for executing other functions not illustrated.

6A-6D, a layout by operation mode of an exemplary English keyboard is shown.

6A illustrates a first mode in which a plurality of characters of a first group are assigned to a plurality of first keys 210, and FIG. 6B illustrates a plurality of characters of a second group assigned to a plurality of first keys 210. FIG. 6C illustrates a third mode in which a plurality of characters of a third group are assigned to the plurality of first keys 210. For example, the first mode may be a lowercase mode, the second mode may be an uppercase mode, and the third mode may be a numeric input mode, but is not limited thereto. The first mode is provided in a default mode. In each mode of operation, different groups of key boards are provided.

6d shows a fourth mode. For example, the fourth mode may be an arrow mode. In the arrow mode, the plurality of first keys 210 are assigned one or more functions of (i) a cursor movement function, (ii) a function for selecting a character, and (iii) a function for editing a character. For example, a cursor movement function is provided using a plurality of arrow keys for up, down, left and right movements, as shown in FIG. 6D. The selection of characters can be made for a character string in the entire range of the document being edited or viewed or in the range in which the cursor is moved. The entire range of documents can be selected by pressing the "Select All" key. When the "Select" key is entered, the cursor is movable, and the arrow keys are used to move the cursor and to select a character string in the range in which the cursor is moved. On the other hand, when the "Select" key is input again, the selection of the character is canceled. "Copy", "Cut" and "Paste" are the same as the shortcut keys (using the "CTRL" key) of the conventional keyboard.

In addition, a tap (TAB), a space (SPACE), and an enter function are allocated to the second key 220 of the first area, and a delete function is assigned to the second key 220 of the second area. The second key 220 of the third area is assigned an English upper / lowercase key board conversion (A / a), numeric key board conversion 123, and arrow key board conversion (ARROW) functions. The user may execute the English letter case switch through the input of the second key 220 in the third area so that the keyboard 200 operates in the first mode or the second mode. In addition, the user may execute the numeric keypad conversion function through the input of the second key 220 in the third area to allow the keyboard 200 to operate in the third mode. In addition, the user may execute the arrow key plate conversion function of the third area to allow the keyboard 200 to operate in the fourth mode. On the other hand, when the shift key is input, the keyboard 200 operates in the second mode once. That is, the keyboard 200 returns to the first mode when the user's input once is completed. If the user wants to input the uppercase English letter twice or more, the user must enter the "A / a" key to execute the English upper / lowercase keyboard conversion function.

Meanwhile, despite the change of the operation mode of the English keyboard, the function assigned to the second key 220 or the third key 230 does not change.

6E-6H, a layout by operation mode of an exemplary Korean keyboard is shown.

FIG. 6E illustrates a first mode in which a plurality of characters of a first group are assigned to a plurality of first keys 210, and FIG. 6F illustrates a plurality of characters of a second group assigned to a plurality of first keys 210. FIG. 6G illustrates a third mode in which a plurality of characters of a third group are assigned to the plurality of first keys 210. For example, the first mode may be a basic vowel (or single vowel) mode, the second mode may be an extended vowel (or vowel) mode, and the third mode may be a numeric input mode, but is not limited thereto. The first mode is provided in a default mode. In each mode of operation, different groups of key boards are provided. On the other hand, it is also possible to input the double vowel by inputting the single vowel two times in succession without executing the second mode.

6h shows a fourth mode. For example, the fourth mode may be an arrow mode. In the arrow mode, the plurality of first keys 210 are assigned one or more functions of (i) a cursor movement function, (ii) a function for selecting a character, and (iii) a function for editing a character. For example, the cursor movement function is provided using a plurality of arrow keys for up, down, left and right movement, as shown in FIG. 6H. The "Select All", "Select", "Copy", "Cut", and "Paste" keys are the "Select All", "Select", "Copy", "Cut", and "Paste" of FIG. 6D, respectively. Performs the same function.

In addition, a tap (TAB), a space (SPACE), and an enter function are allocated to the second key 220 of the first area, and a delete function is assigned to the second key 220 of the second area. The second key 220 in the third area is assigned a vowel key board conversion, a numeric key board conversion 123, and an arrow key board conversion (ARROW) function. The user may execute the vowel keyboard conversion function through the input of the second key 220 in the third area so that the keyboard 200 may operate in the first mode or the second mode. In addition, the user may execute the numeric keypad conversion function through the input of the second key 220 in the third area to allow the keyboard 200 to operate in the third mode. In addition, the user may execute the arrow key plate conversion function of the third area to allow the keyboard 200 to operate in the fourth mode. On the other hand, when the shift key is input, the keyboard 200 operates in the second mode once. That is, the keyboard 200 returns to the first mode when the user's input once is completed. If the user wants to enter the double vowel more than once, he must enter the "Convert vowel" key to execute the double vowel keyboard conversion function.

On the other hand, despite the change of the operation mode of the Korean keyboard, the function assigned to the second key 220 or the third key 230 does not change.

Some keys remain the same at least some of the assigned plurality of characters despite changes in the keyboard.

Some keys are assigned a combination of character language and symbols. Here, the symbol can be input by swiping (in consideration of the fact that the number of times of input is relatively small compared with the character language), as will be described later.

Meanwhile, since the layout of the English keyboard described with reference to FIGS. 6A through 6D and the layout of the Korean keyboard described with reference to FIGS. 6E through 6H are merely exemplary, the arrangement of keys may be variously modified according to embodiments. Can be.

Referring to FIG. 7, for example, a user input gesture may be a tap, a swipe up, a swipe down, a swipe right, a swipe left, or a swipe left. It may include, but is not limited to, one or more types of touch gestures.

The touch on the first key 210 to which two or more letters are assigned and the second key 220 to which two or more functions are assigned are determined by different key inputs according to the type of the touch.

Keys that are assigned a single letter or function can be entered as tabs. In addition, a key to which two or more characters or functions are assigned may be input by swiping. For example, in the case of the first key to which "y", "b", and "n" of FIG. 4 are assigned, "b" located at the center is a tap and "y" located at the upper side is a swipe up. Can be input by swiping down. For example, in the case of the second key assigned to "A / a", "SHIFT", "123", and "ARROW" in FIG. 6A, the arrow keyboard conversion of "ARROW" located on the left side is inputted by a swipe left. can do. Also, although not explicitly shown, swipe lights can also be used to execute the input or function of certain characters in a similar manner.

On the other hand, when no character or function is assigned to the left or right side of the key, the user can register a specific character, character string, file, or the like in advance, and input using swipe light or swipe left.
