Specific features and advantages of the present invention will become more apparent from the following detailed description based on the accompanying drawings. It is to be noted that the detailed description of known functions and constructions related to the present invention is omitted when it is determined that the gist of the present invention may be unnecessarily blurred.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described in detail with reference to the accompanying drawings.

1, the present invention is a one-hand keyboard based on a smartphone, which includes a vowel input unit 100, a consonant input unit 200, a mode setting unit 300, and an area setting unit 400 do.

The vowel input unit 100 can perform a function of inputting a vowel by combining a drag input of the screen and a touch input.

The consonant input unit 200 can rearrange the button position according to the touch priority of the screen and the number of touch frequencies. The consonant input unit 200 includes a priority setting module 210, a consonant frequency setting module 220, and a consonant button placement module 230.

The priority setting module 210 may set the priority of one-hand touch on the screen for each button position.

The consonant frequency setting module 220 can set the number of consonant button use frequencies on the screen for each consonant button.

The consonant button placement module 230 may arrange the consonant buttons of the frequency numbers on the position of consonant buttons in priority order on the screen.

The consonant button of the consonant input unit according to the present embodiment may include a consonant button, a backspace, a space, and a copy button. The Copy button allows you to repeatedly paste the last character you typed.

The mode setting unit 300 is a configuration in which a user interface can be set in a left-hand or right-hand mode by touching or dragging a screen. The buttons of the consonant input area of the left hand or right hand mode of the mode setting unit 300 and the vowel input area may be symmetrically arranged.

The area setting unit 400 can set a vowel region or consonant region as a drag input of the screen. The area setting unit 400 may adjust the size of the input area by dragging the input area in a diagonal direction.

The present invention proposes a new one-hand keyboard which can input characters with one hand on the screen while using a smartphone.

When using the keyboard, you can set up a range of areas where you can enter vowels and consonants in a range that allows you to reach your thumb on the screen of your smartphone with one hand so that you can have a lower miss rate and higher input speed than a conventional keyboard. have.

2 is an exemplary view illustrating an input position of a one-handed keyboard based on a smartphone according to an embodiment of the present invention. As shown in FIG. 2, it is possible to adjust the size of the keyboard by receiving a position where the user can easily reach the thumb.

FIG. 3 is a diagram illustrating an arrangement of a consonant and a vowel input of a one-handed keyboard based on a smartphone according to an embodiment of the present invention. As shown in FIG. 3, consonants and vowels can be arranged.

The consonant input can receive consonants by dividing the part where the keyboard is located into 10 spaces. If you touch 'a' twice, 'ㅋ' is entered.

The one-handed keyboard according to the present embodiment sets different inputs of the consonant and vowel (-, -, l) on the 'Cheonjiyin' keyboard. Consonants are entered as buttons in the lower right part, and vowels can be input via drag and drop motion in the remaining part of the screen.

For example, to input 'ㅘ', you need to input vowel in order of (·) → (ㅡ) → (ㅣ) → (·). Therefore, the vowel 'ㅘ' is combined by touching (·), dragging in the horizontal direction, touching (·), dragging in the vertical direction, and touch (·) motion. Combine vowels with touch (·) motion between 'ㅗ' and 'a'.

When using the keyboard in the on-screen configuration, the input speed and the miss rate may vary depending on the screen size of the smartphone and the size of the user's hand. If the size of the button for inputting the consonants is arbitrarily set, the kind of the smartphone and the result for each user will be different. Therefore, we set the consonant button to be half the size of the screen as the default value and allow the user to adjust the size of the button. However, the size of the button can be set to 1/2 of the screen size and at least 1/4 size.

FIG. 4 is a diagram illustrating a configuration of a screen of a one-handed keyboard based on a smartphone according to an embodiment of the present invention.

As shown in Fig. 4, the keyboard can be placed on the screen of the smartphone with area 1, area 2, area 3, area 4. When you touch the input window (area 3), the buttons (area 1) for inputting consonants are shown on the screen.

These consonant buttons can be semitransparent to see hidden conversations.

Also, when the entered conversation contents are out of the range of the screen, it is possible to move through the scroll (area 4).

Also, in order to implement the actual keyboard input method, the user tried to use the function of the custom keyboard provided by the Android. However, the custom keyboard currently does not support the Korean character, so that the consonant input, the vowel Input, and character combinations.

5 is a diagram showing a VEGA keyboard and an overt keypad.

Keyboard layouts may use existing keyboard combinations (QWERTY, VENTA, VEGA, and NARGAL) to lower the entry barriers that the initial user has on the new keyboard. First, the difference between the VEGA and the skypeople in FIG. 5 is only two combinations of (ㅁ ㅅ) and (ㅇ heh). In order to select a combination of VEGA and Chungjin keyboard, we measured the frequency of consonants with the conversation contents of the group of 8 people from November, 2014 to April, 2015 according to the messenger environment.

FIG. 6 is a diagram illustrating frequencies of consonant sounds of a messenger conversation entered during a predetermined period. In FIG. 6, the frequencies of the conversation contents of the instant messenger conversation for 6 months are as follows.

When comparing the combinations of (ㅇ ㅅ), (ㅇ he /), (ㅇ he), and (ㅇ k), the difference in the frequency of each other is not large in the way that ㅁ is pressed and the ㅅ is pressed. . However, when the combinations are different (ㅇ heh) and (ㅇ ㅁ), there is a difference in the frequency between them, which makes it easier to prioritize the combinations.

Also, the input speed should be fast. To speed up the input speed, consonant placement should take into account the frequency of the pruning, and make sure that a lot of pushing combinations are easily accessible to the user.

7 is a diagram showing frequency of consonants per button. As shown in FIG. 7, it can be seen that the frequencies and the percentages of the combinations are used as the frequency of ((a), (b), (b, It is possible to arrange them in a place where the percentage is higher and can reach more easily.

FIG. 8 is a diagram showing the result of summarizing the order of the keyboard buttons that are easy to reach by hand through questionnaires. As shown in FIG. 8, it is possible to express from the button # 1 in the easy-to-press position to the button # 7 in the uncomfortable position.

FIG. 9 is a diagram illustrating the arrangement of consonants in a one-hand keyboard according to an embodiment of the present invention. The distribution of FIG. 6 shows that the frequency of 'ㅋ' is high, because it repeatedly uses 'ㅋ' or 'ㅠ' in conversation with friends. Accordingly, as shown in FIG. 9, a button having the meaning of 'copy' is inserted in the lower right side, and the 'copy' button can store the previously input one character.

If you do not have this button, you will have to press 20 times from A → B → SPACE → ... → A → ㅋ while using the Copy button, → ... Press '9' to 'Copy' to enter.

FIG. 9 is a view showing the frequency of the one hand keyboard arranged in a crystal. When used in a determined layout, the input speed can be improved by performing keyboard operation without moving a lot of hands, and there is an effect of reducing the typos. In FIG. 9, the button displayed in bold is a button having a higher frequency of use, and the frequency of the button is lower as the button color becomes lighter.

10 is a diagram illustrating a left-hand or right-hand mode setting of a one-handed keyboard according to an embodiment of the present invention. As shown in FIG. 10, the arrangement of the consonants can be arranged according to the frequencies previously observed along the left and right hands.

After implementing the one-handed keyboard, the usability of the one-handed keyboard according to the present embodiment was verified through the Hangeul input speed comparison test using the currently available four kinds of keyboards (QWERTY, VENUE, VEGA, and NARGAL) . All participants were tested with the smartphone they were using. If the smartphone used for testing provided a one-handed mode, it was used and otherwise not used.

The Korean input speed and the typos were compared using a smartphone based one-hand keyboard and four kinds of keyboards according to an embodiment of the present invention. Fifteen test participants (age 23.47 ± 1.53 years) were divided into five groups and tested by keyboards different from the participants' usual keyboards. One day a testing participant performed a five-day keyboard with the keyboard assigned to him. All participants entered the antiquities 1 ~ 4 before the experiment and learned the keyboard input method and experimented.

The purpose of developing a hand keyboard according to the present invention is to solve the inconvenience of operating the keyboard with one hand, so that the testing is performed using the conversation of the messenger application in order to set the condition similar to the assumed situation Respectively. The conversation contents used in the actual messenger application were extracted and the test participants experimented with 500 different syllables for 5 days. The testing method was performed by dividing the articles that the participants had to input on the day into the units transmitted on the messenger. We measured the average input speed and typo daily by synthesizing each input.

The input speed is the number of strokes divided by the sum of the time taken from the first keyboard press to the completion of the sentence for each sentence, and the typos were recorded as the cumulative number of times the backspace key was pressed while the test participant hit the given sentence. The measured values are shown in the table as mean and standard deviation of input speed and typo.

The test results are shown in the following table.

[table]

The above table shows the mean and standard deviation of the number of input strokes and backspace presses. The speed is the number of strokes per second, BS is the rotation, μ is the average, and σ is the standard deviation.

11 is a graph showing an average speed and an average error of each keyboard. As shown in FIG. 11, according to the test result, the keyboard at the input speed on the 5th day shows the second fastest speed and the second fewest number of typed times. The overall input speed and the number of typo tends to improve generally. However, testing was done on a daily basis, so it was very difficult to enter every day, and most keyboards had very good results on day 2 and bad results on day 3.

Analysis of the input speed showed that the input speed was improved as the experiment progressed. In particular, the highest rate of growth was observed when the number of people moved from day 1 to day 2. In addition, we showed fast input speed on the second day because it is helpful to improve the speed by using the copy button because there are many repeated words.

Analysis of the number of typo shows that the number of typo tends to improve as the experiment progresses. However, when the number of ota is very large on the first day, it is analyzed by the table that only the user C has a very high error rate, and the result of the first day average error rate is very high. As a result of interviewing with user C after testing, it was found that he missed to enter the test due to his intention to show the fast input speed result on the first day, and he had a high error rate. On the second day after the test, The results of this study are as follows.

According to the results of the first-day testing of the keyboard testing participants, despite the unfamiliar input method in which consonants and vowels are input separately, the input speed is slower than the other keyboards, It is analyzed that the entry barriers are relatively low for the initial users. In addition, the user B who used the usual Tianjin keyboard among the users of the thrashing test showed a higher adaptability than the other participants. Considering that the basic input method of the thrust is similar to the Tianjin keyboard, the users who are familiar with Tianjin keyboard, And it is expected to show high adaptability to

As a result of interviewing the test participants (A, B, C) about usability after the experiment, it was very satisfied that the hand size of the small participant was able to control the button size of the keyboard. There was no inconvenience for the user, and I gave the opinion that the movements of the hands were small because the positions of the vowels could be different for each position of the buttons on the wide screen of the smartphone which performed the experiment.

FIG. 12 is a diagram illustrating a vowel input portion of a one-handed keyboard based on a smartphone according to an embodiment of the present invention. In FIG. 12, the vowel is input in the red portion. When inputting the 'ㅣ', the user can drag the region from the upper part to the lower portion in the red region or drag the region from the lower portion to the upper portion. When you input 'ㅡ', you can drag left → right or left → right drag in the red area. When you type '·', you can touch the vowel portion of the red area. 12, the vowel input position can be changed within the vowel area, which is a red area of Fig. 12. Since the user can drag and touch at any position within the vowel area, the movement of the hand can be reduced and quick input can be performed. The blue area in FIG. 12 is a range in which scrolling can be applied when the input text is out of the screen.

FIG. 13 is a diagram illustrating a setting screen of a one-handed keyboard based on a smartphone according to an embodiment of the present invention. As shown in FIG. 13, the size of the consonant button can be set by dragging the screen. You can also use the radio buttons to select either the left-hand or right-hand mode.

FIG. 14 is a diagram illustrating a method of reducing a consonant input region by dragging a one-handed keyboard based on a smartphone according to an embodiment of the present invention. In FIG. 14, dragging as in the red arrow can reduce the size of the consonant input area, and if it is desired to increase the size, drag the reverse direction of the red arrow.

15 is a diagram illustrating a method of changing a one-handed keyboard based on a smartphone to a left-handed or right-handed mode according to an embodiment of the present invention. Press the radio button in the mode setting to switch to the left or right hand mode.

As described above, the buttons in the consonant input area are arranged according to the frequency of each consonant, so that the consonant buttons in the consonant input area can be disposed symmetrically with respect to the consonant buttons in the left-hand mode and the right-hand mode.

A one-hand keyboard based on a smartphone according to an embodiment of the present invention can input a consonant input and a vowel input separately with one hand on a screen, and in the case of a consonant input, And it is possible to realize a fast input speed and a low misrecognition by arranging in consideration of a position which is easy to input with one hand.
