Description

[0001] The present invention relates to a compact keyboard for wearable applications,

The present invention relates to a compact keyboard capable of quick input, and more particularly, to a compact keyboard having a plurality of main keys, each of which has a sub key corresponding to each of the plurality of main keys, The present invention relates to a small-sized keyboard for a wearable.

Mobile electronic devices such as cell phones, smart phones, tablet PCs, wearable computers, smart watches, Internet of Thing (IOT), and so on have been developed according to the development of information and communication technology. These electronic devices require input of numbers or characters. Cellular phones usually have a keypad with a physical entity, but since the number of installed keys is limited and multiple key codes are assigned to one key, the key input can not be performed quickly, which is inconvenient.

In order to solve such inconvenience, the present inventor has filed a patent application disclosed in Korean Patent Laid-Open Publication No. 1999-0078618 (titled "key code generation device for fast key input") I got a patent registration. The present invention is characterized in that different keys are assigned and displayed between a plurality of keys and a key code assigned to a combination of both key signals is generated when a portion between two adjacent keys or both keys are pressed together, And to enable quick keystrokes. These keyboards have the same arrangement as the QWERTY type keyboard layout, which comes from the perception that standard keyboard layouts are convenient for users.

Meanwhile, recently developed smart phones and tablet PCs have adopted a virtual keyboard implemented on a touch screen, so that only one key code can be assigned to one key, and as a result, It was. However, even if these virtual keyboards are displayed separately in the display window by the mode of the number mode, the alphabet mode, and the Hangul mode, many keys must be displayed on a single screen in case of using a small screen, which causes frequent misreading at the time of key input. In the case of a tablet PC having a large screen size, since the virtual keyboard can be displayed sufficiently large, it is possible to significantly reduce the misrecognition on the key input, but the mobility becomes relatively inconvenient.

In addition, recently, a TV implemented with a bi-directional function is commercialized. Such a TV requires a convenient input device for inputting a user's request. Although a user's request can be input by a commonly used TV remote controller, the input by the TV remote controller is inconvenient because it is subject to considerable restrictions. Therefore, in recent years, a TV product that can be used by connecting a keyboard to a TV by wire or wireless, in particular, by Bluetooth communication, has been commercialized. The keyboard used here is a standard keyboard of a conventional QWERTY arrangement or a miniaturized keyboard which is a little more simplified than that. Standard keyboards have significant mobility restrictions, and even a somewhat streamlined compact keyboard does not have enough mobility.

More recently, smart watches, wearable computers, and Internet (IOT, IOE), which operate in conjunction with smartphones and tablet PCs or operate independently, are rapidly emerging as new items in information and communication technology. Such a smart watch or the like is expected to inconvenience because a smaller keyboard or keypad must be applied.

FIGS. 6 to 11 are views illustrating the arrangement of keys for Korean and English modes in a compact keyboard according to embodiments of the present invention.

Hereinafter, the present invention will be described in detail with reference to the drawings.

1, the miniature keyboard of the present invention includes a plurality of keys 10, a key signal generating unit 20, a control unit 30, and a memory unit 40. As shown in FIG. The miniature keyboard of the present invention may further include a light emitting portion 50 and may further include a communication portion 60 in the case of having keys of a physical entity.

In the small keyboard of the present invention, the term " small size " means a size smaller than that of a standard keyboard and good mobility. In particular, it means a keyboard having a maximum side length of not more than 10 cm. The miniature keyboard of the present invention can be especially applied to a smart watch. The compact keyboard of the present invention must be implemented in a smaller size in order to be applied to a smart watch.

Here, smart watch refers to an embedded system wristwatch equipped with a function that is more advanced than a general watch, and means to operate as a wearable computer. In general, SmartWatch has a mobile media player function such as FM radio function, audio and video file playback function, and it can be heard through a Bluetooth headset, and it can be connected with smartphone and tablet PC Control functions, and independently execute smartphone functions and wearable computer functions.

In the small keyboard of the present invention, the keys 10 allow a user to input a key, and may have a physical entity, or may be a virtual keyboard implemented on a touch screen by software. The small keyboard of the present invention is preferably a virtual keyboard.

The key signal generator 20 generates a key signal in response to a key input, and preferably generates a key signal corresponding to the key pressed when the user depresses or depresses the keys 10. [ The controller 30 receives the key signal generated by the key signal generator 20 and generates a key code.

A conventional keyboard generates a key signal and a key code corresponding to the pressed key, and immediately transmits the key code to the computer body. The compact keyboard of the present invention may be such that a key code is generated when keys 10 are pressed in the same manner as a conventional keyboard.

Meanwhile, in the small keyboard of the present invention, the key code may be generated by the control unit 30 when the user depresses the key 10 and then releases it. At this time, in the small keyboard according to the present invention, it is preferable that the key signal generator 20 generates a key signal corresponding to the pressed key when the user presses and releases the keys 10, The controller 20 may generate both the key press signal and the key signal and transmit the key signal to the controller 30. The controller 30 may generate the corresponding key code only when the key signal is present. Therefore, it can be understood that the above two configurations are equivalent to the small keyboard of the present invention.

The memory unit 40 stores a combination key code corresponding to a combination of two neighboring keys in the input keys. Such a combination key code is, for example, a key code for a combination of a main key and an auxiliary key dependent thereon in the Korean and English modes. Also, as will be described below, when the small keyboard of the present invention generates a combination key code by a combination of two adjacent main keys, such a combination key code is stored in the memory unit 40. [

The control unit 30 refers to the memory unit 40 when sequentially pressing the two adjacent keys or when the keys are pressed and released simultaneously or within a predetermined time within a predetermined time, A combination key code is determined. When one main key or independent key is pressed or depressed, the main key code or the independent key code corresponding to the key is determined. Here, the independent key and the independent key code are function keys provided separately from the main key and the auxiliary key, and are different from the main key in that they do not form a combination key code in combination with the auxiliary key. In the present specification, this independent key is called an independent key function key when it is a function key.

The light emitting unit 50 may be installed when the small keyboard of the present invention has keys of a physical entity. The light emitting unit 50 is installed as a direct-current LED light emitting lamp below each key, and emits light or releases light according to the control of the control unit. Although the light emitting unit 50 is not necessarily installed, it can be used more conveniently if it is installed.

The communication unit 60 may be a wired or wireless communication unit. When the wired communication unit is a wired communication unit, it is preferably a USB port. In the case of a wireless communication unit, the communication unit 60 is preferably a Bluetooth communication unit. It may be preferable to have both the wire communication unit and the wireless communication unit. If the small keyboard of the present invention is a virtual keyboard implemented in a smart watch, the communication unit may be unnecessary in some cases.

In the small keyboard of the present invention, the keys 10 can be configured for each mode. FIG. 2 and FIG. 3 show the arrangement of the keys for the Hangul mode, and FIGS. 4 and 5 show the layout of the keys for the English mode Respectively.

First, with reference to FIG. 2 and FIG. 3, the arrangement of the keys 10 for the Hangul mode in the compact keyboard of the present invention will be described. FIG. 2 shows a miniature keyboard of the present invention, for example, applied to a round smart watch, and FIG. 3 shows a miniature keyboard of the present invention applied to a square-shaped smart watch.

The small keyboard of the present invention is basically capable of inputting both Korean consonants and vowels with seven main keys 12 and auxiliary keys 14 dependent thereon. Therefore, it can be implemented in a very small size.

Specifically, the seven main keys 12 may be arranged in two rows. Four are arranged in the first column, and three are arranged in the second column. In the main key of the first column, for example, Korean vowels of 'a', 'l', 'ㅡ' and 'ㅓ' are arranged. In the main key of the second column, 'k', ' Consonants are placed. This arrangement considers the frequency of use of Korean consonants and vowels. In some cases, other arrangements are possible.

For example, 'ㅐ', 'ㅑ', 'ㅙ' and 'ㅘ' are arranged in the auxiliary key 14 which is subordinate to the main key 'a'. Here, 'ㅙ' and 'ㅘ' do not correspond to the basic vocabulary of Hangul, so they are not arranged on a regular keyboard. The compact keyboard of the present invention can implement Korean consonants and vowels by a maximum of 35 keys (= 7 x 5) according to the configuration having seven main keys. This is because the number of Korean consonants and vowels many. Therefore, the small keyboard of the present invention can display the Korean alphabet sound not displayed on the general keyboard, and can perform quick input by a single operation.

On the other hand, for example, 'ㄲ' is input by inputting 'A' twice successively without displaying 'ㄲ', 'ㄸ', 'ㅃ', 'ㅆ' and 'ㅉ' on the keyboard of the present invention So that it is possible to arrange more Korean vowels in the small keyboard of the present invention. The small keyboard of the present invention illustrated in the figure is to perform input by this method.

Next, for example, 'ㅚ', 'ㅟ', 'ㅢ' and 'ㅞ' are arranged in the auxiliary key 14, which is subordinate to the main key '1' For example, 'ㅗ', 'ㅜ', 'ㅛ', and 'ㅠ' are placed, and auxiliary keys that depend on the main key '에는' include 'ㅔ', 'ㅕ', 'ㅝ' &Quot;

For example, 'A', 'c', 'd' and 'ㅁ' are allocated to the auxiliary key which is dependent on the main key 'ㄴ' For example, 'ㅋ', 'ㅒ', 'ㅌ', and 'ゃ' are placed in the auxiliary key that is dependent on the main key 'ㅎ'.

The shape of the main key 12 in the compact keyboard of the present invention is not particularly limited as long as it can be conveniently performed by pressing the main key independently and simultaneously pressing the main key and the auxiliary key 14 at the same time. In addition, the arrangement position of the auxiliary key disposed adjacent to the periphery of the main key in the small keyboard of the present invention is not particularly limited as long as it is convenient to simultaneously press the main key and the auxiliary key. Typically, it may be disposed at the top, bottom, left, and right sides of the main key, or at the positions of the top, top, bottom, and top of the main key. And may be arranged in any combination of such positions. FIGS. 2 and 3 show examples in which the auxiliary keys are disposed at the positions of the upper, upper, lower, and upper sides of the main key.

In the small keyboard of the present invention, it is convenient to use that the auxiliary keys are arranged smaller than the main keys. It is preferable that the auxiliary key is disposed adjacent to the main key so that the belonging to the main key group is arranged visually intuitively. Therefore, it is preferable that the main key has a shape in which a part is removed from a key shape of a polygonal or circular shape such as a quadrangle, a pentagon, or a hexagon, and an auxiliary key in a shape such as a quadrangle or a circle is disposed in the removed portion of the main key Do. According to such a structure, the user can intuitively recognize the main key and the auxiliary key in one group, thereby facilitating the input.

The main key 12 generates a corresponding key code when it is depressed by itself or when depressed and released. Korean characters and a vowel corresponding to the key code of the main key 12 are displayed on the main key 12. [ The keycode generated by the pressing of the main key 12 is preferably displayed on the display window 18 so that the user can confirm the contents inputted by the user. This is the same for the generated combination key code.

In the present invention, the auxiliary key 14 is arranged to be subordinate to the main key 12 means that the auxiliary key 14 is disposed adjacent to the periphery of the main key 12, It means that it can not generate any key code by pressing only the key and contributes to key code generation when it is pressed at the same time with the main key 12. [

Therefore, when one main key 12 and one auxiliary key 14 dependent on the main key 12 are pressed at the same time in the compact keyboard of the present invention, a combination key code corresponding to the combination of the main key 12 and the auxiliary key 14 Is generated. The combination key code is stored in the memory unit 40 and the control unit 30 stores the combination stored in the memory unit 40 when one main key 12 and one auxiliary key 14 dependent thereon are pressed at the same time. And determines a combination key code to be input by referring to the key code. On the other hand, if only one main key 12 is pressed, the control unit 30 determines the main key code corresponding thereto as a key code to be input.

In the small keyboard of the present invention, when there is an input other than the above-mentioned input type, the input is determined to be an invalid input, and the control unit does not perform any input processing. For example, when one main key 12 and two auxiliary keys 14 are simultaneously pressed, two main keys 12 and one auxiliary key 14 are simultaneously pressed, .

On the respective auxiliary keys 14, a Korean consonant and a vowel corresponding to a combination key code of the main key 12 and a corresponding auxiliary key 14 dependent thereon are displayed for the convenience of the user.

The small keyboard of the present invention further includes three function keys 16, that is, an independent key function key 16, separate from the main key 12 and the auxiliary key 14 in which Hangul consonants and vowels are arranged in the Hangul mode desirable. As shown in FIGS. 2 and 3, the independent key function key 16 is preferably a space key, an enter key, and a backspace key in the Hangul mode.

Next, with reference to FIG. 4 and FIG. 5, the arrangement of the keys 10 for the English mode in the small keyboard of the present invention will be described. FIG. 4 shows a small keyboard of the present invention applied to a smart watch of a round shape, for example. FIG. 5 shows a small keyboard of the present invention applied to a square-shaped smart watch.

The small keyboard of the present invention is basically capable of inputting all of the English alphabets with seven main keys 12 and subordinate keys 14 dependent thereon. Therefore, it can be implemented in a very small size.

Specifically, the seven main keys 12 may be arranged in two rows. Four are arranged in the first column, and three are arranged in the second column. For example, the English alphabet of 'A', 'E', 'I' and 'N' is arranged in the main key of the first column and the English alphabet of 'Q' and 'U' Key " The key assignment of the main key is arranged based on the use frequency of the alphabet, but it is possible to arbitrarily change it.

For example, 'B', 'C' and 'D' are arranged in the auxiliary key 14 which is subordinate to the main key 'A'. For example, 'F', 'G' and 'H' are allocated to the auxiliary key 14 that is subordinate to the main key 'E' 'K' and 'L' are arranged, for example, 'M', 'O' and 'P' are arranged in auxiliary keys which are subordinate to the main key 'N'.

For example, 'R', 'S', and 'T' are allocated to auxiliary keys that are dependent on the main key 'Q', and auxiliary keys that are subordinate to the main key 'U' ',' X 'and' Y 'are arranged. For example,' Z ','. (Period) 'and' backspace 'are allocated to the auxiliary key which is subordinate to the main key' enter '.

In the present invention, a function key refers to a key for performing a function other than the input of symbols such as Korean consonant and vowel, English alphabet, and punctuation. The function key includes a Caps Lock key, a space key, a shift key, A backspace key, an enter key, a Korean / English mode conversion key for converting from Hangul mode to English mode, an English mode to Hangul mode, and a numeric mode conversion key for converting from Hangul mode or English mode to numerical mode. Although the space key may be regarded as a space character input, in the present invention, the space key is classified as a function key in that a space input function is given rather than a character input.

These function keys may be assigned to the independent key function keys 16 arranged as independent keys in the small keyboard of the present invention or may be assigned to the main key function keys 13 arranged as the main keys, And may be assigned to the auxiliary key function key 15. 4, the CapsLock key (indicated by Caps), the space key and the shift key are assigned to the independent key function key 16, the enter key is assigned to the main key function key 13, and the backspace key Is assigned to the auxiliary key function key 15. This assignment is somewhat arbitrary, but it is based on the habits of users and may be more convenient to use than other forms of assignment. 7 to 11 show different assignment examples of the function keys.

In the English mode, the auxiliary key is composed of three auxiliary keys in one main key, except for auxiliary keys that are subordinate to the main key 'U'. Exceptionally, there are four auxiliary keys that depend on the main key 'U'. This configuration is intended to implement all the alphabets and implement the necessary function keys.

In the English mode, the shape and size of the main key 12 and the shape, size, and arrangement of the auxiliary key 14 are the same as those described above for the Hangul mode.

The main key 12 generates a corresponding key code when it is depressed by itself or when depressed and released. An English alphabet and a function key indication corresponding to the key code of the main key 12 are displayed on the main key 12. English alphabets and function keys corresponding to the combination key code of the main key 12 and the corresponding auxiliary key 14 dependent thereon are displayed on each auxiliary key 14 for the convenience of the user.

The small keyboard of the present invention may further include three function keys 16 in addition to the main key 12 and the auxiliary key 14 in which the English alphabet and the function key are arranged in the English mode. These function keys are Caps Lock key, Space key, Shift key, Backspace key, Enter key, Korean / English mode conversion key for converting from Korean mode to English mode, or English mode to Hangul mode, 4 and 5, in the English mode, a Caps Lock key (shown as Caps in the drawing), a space key, and a shift key Key.

In addition to the above, the Korean language mode is also applied to the English language mode.

FIGS. 6 to 11 illustrate the arrangement of the keys for the Hangul mode and the English mode in the small keyboard according to the embodiments of the present invention.

First, referring to FIG. 6, the key arrangement is not different from the key arrangement of FIGS. 2 to 3 except that a combination mode conversion key 19 'is added.

The combination in the combination mode conversion key 19 'generates a new key code by a combination of two neighboring main keys when the two main keys adjacent to each other are simultaneously pressed or released from the main keys 12 Quot; virtual combination key ". The mode conversion key in the combination mode conversion key 19 'is a one-to-one mode conversion key for converting from Hangul mode to English mode, or from English mode to Hangul mode, and a numeric mode conversion It means something like a key. In FIG. 6, reference numeral 123 (19 ') denotes a numeric mode conversion key for converting from Hangul mode or English mode to numeric mode. Mode is a mode for converting from Hangul mode to English mode, Quot;

Therefore, the combination mode change key 19 'is a virtually existing key, not an actual key, and is implemented when two neighboring main keys 12 are pressed at the same time. 6, when the main key 'o' and the main key 'o' are pressed at the same time, the main mode 'o' and the main key ' .

The above description also applies to Figs. 7 to 11. Fig. 8 and 10, the mode key is not assigned to the combination mode conversion key 19 'but is assigned to the independent mode conversion key 19. Independent in the independent mode conversion key 19 means that the mode conversion key is not assigned to the virtual combination key but is assigned to an actual independent key. 8 and 10, the mode key 19 or 19 'is assigned to the independent key function key 16 or 16'.

10, the small keyboard of the present invention is assigned not only to the main key 12 and the auxiliary key 14 but also to the main key combination key 17 in the English mode. Herein, the main key combination key 17 refers to a virtual combination key generated by a new key code by a combination of two adjacent main keys when the user presses or simultaneously depresses the two adjacent main keys. There is a difference in that the main key combination key 17 is not different from the combination mode conversion key 19 'in that it is assigned to a combination of two neighboring main keys, but it is assigned an English alphabet. Thus, the main key combination key 17 is arranged between all the main keys, that is, one among the seven main keys.

In particular, in the small keyboard exemplified in Fig. 10, four main keys 12 are arranged in the first column, three are arranged in the second column, and function keys , That is, independent key function keys 16 'and 19 are disposed, and when the independent key function keys 16' and 19 disposed in the second column and the main key 12 adjacent thereto are pressed simultaneously, A virtual combination key for generating a new key code is arranged by a combination of two adjacent independent key function keys 16 'or 19 and a main key 12. [ Specifically, a shift key is assigned to the left independent key function key 16 ', and a mode key is assigned to the independent key function key 19 to the right. The English alphabet 'T' is assigned to the left independent key function key, that is, the combination of the shift key 16 'and the main key' R ', and the right independent key function key, Is assigned a numeric mode conversion key 19 'as a combination mode conversion key.

In the above description, the compact keyboard of the present invention is described for Korean and English input. However, the present invention can be applied to other languages such as German, French, etc. corresponding to English alphabet instead of English alphabet. In addition, if the number of phonemes representing the language of the country corresponds to a suitable number, the small keyboard of the present invention can express the language of such a country.
