Description

Braille input method suitable for touch panel

The invention relates to a braille input method, in particular to a braille input method designed by using touch panel technology, multi-touch technology and blind dot-word technology.

With the rapid development of touch panel technology, such as resistive, capacitive, infrared, ultrasonic and electromagnetic, various touch panel technologies have been developed, and single-touch to multi-touch technology The evolution, like Apple Co.'s multi-touch US patent 7,479,949, has been widely used in personal digital assistants (PDAs), mobile phones, tablets, information appliances and other equipment. In contrast, traditional button input devices have also been quickly replaced by these touch panels. Such technological development has brought a lot of convenience to our lives. When we enjoy the convenience of technology, it is caused by visually impaired people. Another obstacle and digital gap, if based on these technologies, further design the operation interface and method for the visually impaired, can help them shorten the digital gap, and enjoy the convenience brought by technology with the discerning person.

Braille is a touch-reading and input system designed for the blind. It gives different meanings to different meanings instead of ordinary words in the discerning society. The Braille is the Frenchman Braille (1809-1852). It was officially designed and completed in 1387. It was officially adopted by the countries in 1845. Each square has six dots of cells, which are two points of cells and three points of cells. For the convenience of identification, each point cell is numbered, and the three points on the left are the first point, the second point, and the third point, and the three points on the right are the fourth point and the fifth point. The sixth point, taking China as an example, the Braille is based on the Brill's Braille system, with different Braille symbols representing different words, including 21 initials, 16 finals, 22 combined rhymes and five tonal symbols. For example, different braille symbols are used to represent 26 English letters.

In the past, visually impaired people use the touch physical button position to input the above six-point words. For example, the visually impaired can be positioned by touching the F key of the personal computer keyboard and the J key bump, but with the rapid development of the technology, the keyboard Gradually after being replaced by the touch panel, the visually impaired person can't input by touching the physical button position as before, thus the problem that the touch word cannot be input on the touch panel, causing digital drop and inconvenience.

On some touch phones and tablets, there is a voice prompt that slides on the virtual keyboard of the touch screen with a single point, while sliding, and when sliding to the letter or symbol to be input, use the finger to double. The Click panel confirms the way the input is made, but this method is not easy for the visually impaired, and it takes a lot of time to move to find the desired symbol.

It can be seen that there are still many shortcomings in the above-mentioned methods of use, which is not a good design, but needs to be improved.

In view of the shortcomings derived from the above-mentioned conventional methods, the inventor of the present invention has improved and innovated, and after years of painstaking research, he finally succeeded in research and development of a braille input method suitable for touch panels.

The object of the present invention is to provide a braille input method suitable for a touch panel, in particular to a touch panel technology, a multi-touch technology and a blind dot-word technology, and a set of touch panel is designed. The input method suitable for the visual habits of the visually impaired can enable the visually impaired to input the braille quickly and accurately, shorten the digital gap, and enjoy the convenience brought by the technology as the average person.

The method for inputting a braille function for a touch panel that achieves the above-mentioned object is a combination of a sequence and a position of a plurality of fingers simultaneously touching the touch panel to represent different character numbers, and according to the size of the touch panel The design uses different methods. When the size of the touch panel is sufficient, the touch panel is touched by six fingers at the same time, as the reference and the beginning of a braille input, according to the word to be input, the corresponding finger is left at the same time. Touch the touch panel and release other unwanted fingers. After comparing with the reference, judge the finger number of the touch panel, and use this as the input character number. Finally, release all the fingers as a dot. End of input; when the touch panel is not large enough, you can change to use one finger at a time, touch the touch panel twice to complete a braille input, or use two fingers at a time, three touches at a time. Touch the touch panel to complete a braille input method. When two points are not needed, after the two fingers are released, a single finger is drawn on the touch panel to indicate a specific symbol. The finger is pushed in the same way; when the size of the touch panel is very large, the touch panel is touched by a specific finger as a reference reference position, and the reference finger is simultaneously touched with other corresponding fingers according to the point character number to be input. The touch panel is used as the beginning of a braille input, and then the difference in distance between the other fingers is calculated from the reference position, thereby determining which fingers touch the panel at the same time, and using this as the input character number, and finally placing Open all fingers as the end of a Braille input; if you need to cancel an input error, you can cancel the input by drawing a specific symbol on the touch panel with a single finger.

The above-mentioned braille input method for a touch panel is combined with a computer readable recording medium. The recording medium stores a program for performing the above method, and the computer readable recording medium includes: a personal digital assistant. Electronic devices such as mobile phones, tablet computers, and information appliances.

When inputting a braille using the method of the above invention, in order to speed up the input speed of a common word, it is possible to input only the first complete dot code of each character in the text phrase to be input, plus a digital dot code, and then one Start numbering, sequence out the last dot code, all the words that match the first complete dot code combination of each word entered, and use the last received dot code as the selected phrase number to complete the input method. To speed up the input of common words. You can also use the first complete dot code for each text to list all the first complete dot code combination phrases for each word that match the input. The user selects the correct phrase in the list and completes the input.

After inputting the character number, you can use the conversion table to convert the entered character number into a text symbol, and use the display and voice prompts to allow the visually impaired to confirm the correctness and correction of the input content at any time. The visually impaired person quickly and accurately enters the text on the touch panel.

FIG. 1 is a flow chart of the first method of the present invention. First, the first step is to simultaneously touch the touch panel with six fingers as the reference and the start S100 of a braille input, and the corresponding position is determined according to the relative positions of the six fingers. The point number is followed; then the second step leaves the corresponding finger according to the point word to be input, and releases the other finger S101; the third step compares with the reference to determine the finger number of the touch panel, and For the input point number S102; in the above two steps, you can also use three fingers at a time, touch the touch panel twice to complete a braille input, and use two fingers at a time, three touches at a time. Touch the touch panel to complete a braille input. The step is to touch the panel with two fingers at the same time as the beginning of each two-point input, and all the two fingers are released as the end of each two-point input. And before the two fingers are all released, the finger touching the panel is the input word. When the two points are not needed, after the two fingers are released, the specific symbol is drawn on the touch panel with a single finger. Said that when When the point is too long, the original input step can be maintained, three fingers and so on; the fourth step is to release all the fingers as a point input end S103, in this step, if the input error is found to be canceled, You can cancel the input by simply drawing a specific symbol on the touch panel.

2 is a second method flow of the present invention. First, the first step is used as a reference reference position S200 with a specific finger; then the second step simultaneously touches the reference finger with the corresponding finger according to the point character number to be input. The control panel is used as the start of a braille input S201; the third step calculates the distance difference between the finger of each touch panel and the reference finger to determine which fingers are pressed, wherein the distance difference between each finger position can be directly specified The experience value can also be analyzed through a pre-training step to record the average distance difference between the fingers of the user when pressed, as a basis for subsequent detection to determine which fingers are simultaneously pressed according to S202; the last step is to release all the fingers as one The end of the braille input S203, in this step, if the input error is found to be canceled, the specific symbol can be drawn on the touch panel to cancel the input.

In the implementation of the method of the present invention, only the difference between the input word type and the corresponding word symbol conversion table is different, and the switching between different language characters can be performed by using a finger on the touch panel. The manner of the specific symbol is switched; in order to further understand the technical content of the present invention, two preferred embodiments are used together with the description. In the embodiment, the character numbers represented by the fingers are as shown in FIG. 3, and the left index finger is used. The middle finger and the ring finger represent the braille "1, 2, 3". The right index finger, the middle finger and the ring finger represent the braille "4, 5, 6". You can also use the one-hand index finger, the middle finger and the ring finger to represent the braille "1. 2,3" and Braille "4,5,6" are entered in two steps, or one-handed index finger, middle finger represents the word "1,2", "3,4", "5,6" in three inputs. ,described as follows:

The first embodiment: the user wants to input the word "H", the steps are as follows:

In the following steps, the steps (1) to (3) in the embodiment may be changed to use two fingers at a time, and the touch panel is touched three times to complete the input, and the first time the character is “1, 2", the second time you enter the word "3,4", the third time you enter the word "5,6", for example: step (1) first touch two fingers, the right index finger and the middle finger simultaneously Control panel, step (2) remove the index finger and middle finger from the touch panel, indicating that you want to enter the braille word "1, 2", and return to step (1) to touch the touch panel with two fingers at the same time. The fingers are released, and a straight line is drawn from left to right with a single finger on the touch panel, indicating that the word "3, 4" is not to be typed, and then returning to step (1), the two fingers of the right index finger and the middle finger are simultaneously touched. Touch panel, step (2) release the right middle finger, leaving the right index finger to indicate the word "5", step (3) to release two fingers, complete the three-point input of a complete word.

The second embodiment: the user wants to input the word "prince", the steps are as follows:

(1) Use the left and right thumb as the reference reference point.

(2) With the left thumb and the thumb, index finger, middle finger and ring finger of the right hand, touch the touch panel at the same time, calculate the distance difference between the finger touching the panel and the thumb of the hand, and detect that the right index finger, middle finger and ring finger are pressed simultaneously. .

(3) Release all your fingers.

(4) In the display and voice prompt, the user currently receives the input point character number "4, 5, 6", and converts it into a phonetic symbol "透过" through the figure 5 (a)-(d) Mandarin dot character number conversion table. If the user finds that the input is wrong, the right-hand index finger is used to draw a straight line from right to left on the touch panel to cancel the input and return to step (1), otherwise continue to the next step.

(5) After touching the touch panel with the left thumb, middle finger and right thumb, the distance between the finger of each touch panel and the reference finger is calculated, and the left middle finger is pressed.

(6) Release all your fingers.

(7) The user is prompted by the display and voice to receive the input point character number "2" and converted into the corresponding text "two sounds". When the tone symbol is received, the previously input symbols are combined, and the phonetic transcription is converted. The symbol "ㄨㄤˊ" converts the phonetic into a national character, and prompts the user to select the input as the king of the dynasty. If the user finds that the input is wrong, the right index finger is on the touch panel by the right. Draw a straight line to the left to cancel the input and return to step (1), otherwise continue to the next step.

(8) After touching the touch panel with the left thumb, index finger, middle finger and right thumb and middle finger at the same time, after calculating the distance difference between the finger of each touch panel and the reference finger, the left index finger, the middle finger and the right middle finger are detected. under.

(9) Release all your fingers.

(10) The user and the voice prompting the user to receive the input point character number "1, 2, 5" and convert it into the phonetic symbol "ㄗ". If the user finds that the input is wrong, the right index finger is used on the touch panel. Draw a straight line from right to left to cancel the input and return to step (1), otherwise continue to the next step.

(11) After touching the touch panel with the thumb of the left hand, the index finger and the thumb of the right hand, after calculating the distance difference between the finger of each touch panel and the reference finger, the left index finger is detected to be pressed.

(12) Release all your fingers.

(13) The user is prompted by the display and voice to receive the input point character number "1", and the corresponding text "soft" is converted. When the tone symbol is received, the previously input symbols are combined and the phonetic symbol is converted. ㄗ‧”, then convert the phonetic into a national character, and prompt the user to select the child as the “child”.

When calculating the distance difference between each finger position, the method of directly specifying the experience value may be used, or the pre-training step may be used to analyze and record the average distance difference when the user presses each finger, for example, the user is required to use the most natural way. The left and right hand thumb, index finger, middle finger and ring finger can be touched on the panel several times at the same time to obtain the average distance difference, which is used as a basis for subsequent detection to determine which fingers are pressed at the same time.

When using the above two steps to input a dot, when you are very familiar with the phrase you want to input, you can enter only the first complete dot code of each text in the text phrase, and a numeric dot code, and then one Start numbering, sequence out the last dot code, all the words that match the first complete dot code combination of each word entered, and use the last received dot code as the selected phrase number to accelerate the common words. Input, for example: to enter the word "prince", the first word "king", its first complete braille is "4,5,6", the second word "child", its first The complete braille is "1, 2, 5", and the digit Braille "2" stands for number 1. The phrase that matches the first two complete lexicons contains "1. Prince" and "2. 妄 自". Since the input is very familiar with the sequence number of 1, the effect of quickly inputting common words can be achieved when the above steps of the quick input method are used. You can also use the first complete dot code for each text to list all the first complete dot code combination phrases for each word that match the input. The user selects the correct phrase in the list and completes the input.
