Description

Technical Field

[0001] This invention relates to the field of device input recognition technology, and in particular to input recognition methods, payment processing methods, and electronic devices suitable for the blind. Background Technology

[0002] Secure payment is especially important for electronic devices. For vulnerable groups like the blind, the security and convenience of using electronic devices are difficult to guarantee. Blind people are prone to having their payment passwords leaked or being entered incorrectly when using electronic devices, causing inconvenience. Summary of the Invention

[0003] The technical problem to be solved by this invention is to provide an input recognition method, a payment processing method, and an electronic device suitable for blind people, to ensure the input security of blind people, and at the same time reduce the probability of blind people making incorrect inputs.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: An input recognition method suitable for blind people, characterized in that it is applied to a target electronic device, the method comprising: A touch screen input page is created on the touch screen of the target electronic device. The touch screen input page includes a function key area, a character key area with a preset number of pages, and a page turning trigger control. The area of ​​the character key area on a single page accounts for more than one-third of the touch screen of the target electronic device, and the character key areas with the preset number of pages are different. In response to a touch of the page-turning trigger control, the character key area is switched within the character key area of ​​the preset page number; During the payment phase of the target electronic device, in response to touch screen operation in the character key area, a corresponding key is generated for payment verification.

[0005] To solve the above-mentioned technical problems, another technical solution adopted by the present invention is as follows: A payment processing method suitable for blind people includes the following steps: Obtain payment requests from blind individuals; Based on the aforementioned payment request from the blind person, the touchscreen input page is invoked on the target electronic device. In response to a touch of the page-turning trigger control, the character key area is switched within the character key area of ​​the preset page number; In response to a touch operation on the character key area, the system parses and obtains the string corresponding to the touch operation, and initiates payment based on the string.

[0006] To solve the above-mentioned technical problems, another technical solution adopted by the present invention is as follows: An electronic device includes a memory, a processor, and a computer program stored in the memory and capable of running on the processor, wherein the processor executes the computer program to implement the steps of the above-described input feedback method for the blind.

[0007] The beneficial effects of this invention are as follows: This application provides an input recognition method, payment processing method, and electronic device suitable for blind people. By creating a touchscreen input page on the touchscreen of the target electronic device, the touchscreen input page includes a function key area, a page-turning trigger control, and a character key area exceeding one-third of the entire touchscreen. The character key area has a preset number of pages, with each page displaying different password characters. This reduces the pressure of arranging password characters in each character key area, allowing each character key area to provide a larger key area for the corresponding password characters, thereby improving the blind person's ability to click on each character key. Accuracy: By responding to the touch of the page-turning trigger control, users can switch between character key areas within a preset number of pages. The page-turning operation allows users to find the desired password characters. During the payment phase of the target electronic device, the touchscreen operation of the character key area is responded to, and the corresponding key is generated for payment verification. This application also makes it difficult for others to fully access all the input content of a blind person through the page-turning operation, ensuring the input security of blind people. Simultaneously, it reduces the probability of incorrect input and improves input efficiency. Therefore, this application, targeting special groups such as the blind, can simultaneously achieve both security and convenience when using electronic devices. Attached Figure Description

Detailed Implementation

[0009] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0010] In the following description, specific details such as particular system architectures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of this application. However, those skilled in the art will understand that this application may also be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods have been omitted so as not to obscure the description of this application with unnecessary detail.

[0011] It should be understood that, when used in this application specification and the appended claims, the term "comprising" indicates the presence of the described features, integrals, steps, operations, elements and / or components, but does not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components and / or a collection thereof.

[0012] References to "one embodiment" or "some embodiments" as described in this specification mean that one or more embodiments of this application include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. The terms "comprising," "including," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.

[0013] In related technologies, electronic devices such as mobile phones, computers, and tablets, limited by the number of characters displayed and screen size, have relatively limited key areas on their keyboards, especially English keyboards. When blind people operate touchscreens, they are prone to accidentally touching other keys around the desired key, resulting in decreased input accuracy and efficiency. Furthermore, the entire input process is inevitably visible to others, who, even if unable to see the screen, can easily guess what the blind person is typing based on finger movements and the typical key layout, thus posing a safety hazard.

[0014] Especially in POS device scenarios, when blind people use POS devices to enter PINs for payments, relying on tactile positioning, even if they are familiar with the standard number layout of "1-2-3 / 4-5-6 / 7-8-9 / 0", they are very prone to accidentally pressing adjacent keys due to finger touch deviations (e.g., intending to press "1" but touching "2" or "4", or intending to press "0" but touching "8"). Furthermore, in POS device scenarios, a single accidental touch can lead to an incorrect PIN. If three consecutive accidental touches occur, most banks will trigger a temporary account lock mechanism, directly interrupting the payment process. This may even require the blind person to bring their identification to the bank to unlock the card, increasing additional time and effort costs. Some POS devices lack user-friendly designs for "PIN modification / deletion" (such as a "backspace" key without clear tactile markings). Once accidentally touched, blind people cannot quickly correct their input and can only choose "cancel input" to start over, further prolonging the operation time and exacerbating their anxiety in public settings. While fingers can be covered by the grip of a mobile phone when inputting data on ordinary electronic devices, POS devices are usually placed on a counter surface, and the blind person's hands must be fully exposed to the outside world. Others can not only guess the password by combining the "area where the finger is pressed" (e.g., pressing the upper left corner corresponds to "1", and the middle corresponds to "5") with a fixed number layout, but also further narrow down the guessing range by the "number of presses" (e.g., a 6-digit password corresponds to 6 presses), or even directly judge the number by observing the finger's landing point.

[0015] To address the aforementioned problems, this application provides an input recognition method, a payment processing method, and an electronic device suitable for blind people. The following is a detailed description of one such input recognition method for blind people.

[0016] The input recognition method for blind people in this application can be used in various scenarios where manual input is required on electronic devices, such as mobile phone input, tablet input, library service terminal input, etc. The electronic devices used in this application may include mobile phones, e-readers, POS devices, etc., with POS devices and other payment-related devices being particularly suitable. The method in this application can be used for input by blind people, improving convenience and security.

[0017] The following details the input recognition method for the blind according to the present invention, with reference to the appendix. Figure 1 and Figure 3 The method includes steps 102-106, as follows: In step 102, a touch input page 300 is created on the touch screen of the target electronic device. The touch input page 300 includes a function key area 306, a character key area 304 with a preset number of pages, and a page turning trigger control. The area of ​​the character key area 304 on a single page accounts for more than one-third of the touch screen of the target electronic device, and the character key areas 304 with the preset number of pages are different.

[0018] Combination Figure 3 In one embodiment of this application, taking a POS device with a 5.5-inch touchscreen as an example, its screen size is approximately 12.1cm × 6.8cm, and its total area is approximately 82.28cm². 2 The touchscreen input page 300 design includes: placing the function key area 306 at the bottom of the screen, occupying approximately 15% (12.34cm) of the screen area. 2 It includes three core function keys, each measuring 2cm x 1.5cm to facilitate navigation for the visually impaired: the "Delete" key on the left, the "Assistive Key" in the middle, and the "Confirm" key on the right. The character key area 304 is located in the central core area of ​​the screen, occupying approximately 40% of the screen area (32.91cm). 2 The key size is 4cm x 4cm. Taking numbers as an example, four pages of different characters are preset. The character key area 304 on page 1 only displays "1, 3, 5" alternately; the character key area 304 on page 2 only displays "2, 4, 6"; the character key area 304 on page 3 only displays "7, 8, 9"; and page 4 only displays "0, X, #". In this way, others cannot obtain the complete password by "continuously observing the finger's landing point"—even if they see the key position on one page, they cannot associate it with the characters on other pages, effectively cracking the "guessing the password through finger movements" method, greatly improving security. At the same time, the larger size of each character key in the character key area 304 reduces the probability of accidental touches by blind people.

[0019] In step 104, in response to the touch of the page-turning trigger control, the character key area 304 is switched in the character key area 304 of the preset page number.

[0020] Continue with Figure 3 For example, in one embodiment of this application, when a blind person needs to switch from page 1 ("1, 3, 5") to page 2 ("2, 4, 6") when entering a password at the POS terminal, they only need to touch the page-turning trigger control with the "↓" Braille mark on the right edge (triggered by a single-point press), and the device will immediately switch the character key area 304 to page 2. The form of the page-turning trigger control includes, but is not limited to, sliders, rotary buttons, etc., and is not limited here. For example, this application can set page turning to sliding or rotating a knob in a specific area. In this way, blind people can operate accurately without sight, which not only improves the accuracy of operation, but also prevents others from prying into the complete password by turning pages.

[0021] In step 106, during the payment phase of the target electronic device, in response to the touch screen operation of the character key area 304, the corresponding key is identified and generated for payment verification.

[0022] During the payment phase of the target electronic device, for touch screen operations on different character key areas 304, the target electronic device can provide corresponding preset prompts, including but not limited to sound signals, vibration signals, or a combination of both, so that blind people can know the content they are currently inputting and thus verify that their input method is correct. The preset prompts will be explained in detail below.

[0023] Therefore, this application creates a touchscreen input page on the touchscreen of the target electronic device. The touchscreen input page 300 includes a function key area 306, a page-turning trigger control, and a character key area 304 with an area exceeding one-third of the entire touchscreen. The character key area 304 has a preset number of pages, each displaying different password characters. This reduces the pressure of arranging password characters in each character key area 304, allowing each character key area 304 to provide a larger key area for the corresponding password characters, thereby improving the accuracy of clicks on each character key by blind users. Furthermore, by responding to page-turning triggers… Touching the control allows users to switch between character key areas 304 on preset pages. Users can navigate through these pages to find the desired password characters. During the payment phase of the electronic device, the touchscreen operation on the character key area 304 triggers the generation of a corresponding key for payment verification. This application also makes it difficult for others to fully access all the input from a blind person, ensuring input security and reducing the probability of mis-input, thus improving input efficiency. Therefore, this application addresses the needs of blind individuals by simultaneously achieving both security and convenience when using electronic devices.

[0024] In one embodiment of this application, at least one preset touch mode is provided for each character key area 304 of a page in a preset number of pages, and all preset touch modes are used to switch to the character key area 304 of other pages in the preset number of pages in a one-to-one correspondence.

[0025] Using the aforementioned four pages of number keys as an example, when the character key area 304 displayed on the POS terminal is page 1 ("1, 3, 5"), a blind person can use the preset touch method for the "1" key to jump to page 2 ("2, 4, 6"), the preset touch method for the "2" key to jump to page 3 ("7, 8, 9"), and the preset touch method for the "3" key to jump to page 4 ("0, X, #"); similarly, for "2, 4, 6..." The three buttons on page 2 also have preset touch control methods for previous pages. In this way, compared to traditional page-turning controls where the operation is easily observed by others, the jump operation in this solution is completely synchronized with the "touch character keys," making it impossible for others to distinguish whether the blind person is inputting or turning pages. For example, if a blind person touches and holds the "1" key to jump, from another person's perspective, it only appears as "the finger is on the '1' key for 2 seconds," making it impossible to determine whether it's "hesitation before input" or "jumping operation," thus avoiding voice leakage in public. Furthermore, each page's character key area 304 has a preset touch control method for jumping to any other page's character key area 304, reducing the time spent by blind people switching pages and improving input efficiency.

[0026] In one embodiment of this application, the page-turning trigger control may be multiple, and the multiple page-turning trigger controls can correspondingly trigger the corresponding character key area 304. For example, there are three corresponding page-turning trigger controls, which can respectively turn the page from the character key area 304 of 135 to 246, 789 and 0, X, #. This application may also set 0 in the middle of the function key area 306, and this application does not impose any restrictions on this.

[0027] In one embodiment of this application, combined with Figure 4 It can be seen that, compared to Figure 3 The design is based on a portrait-oriented page layout, but a landscape-oriented page layout is also provided. In landscape mode, each character key in the character key area 304 has a wider area, allowing blind users more freedom of finger placement and more accurate input on the touchscreen. Furthermore, to accommodate manual operation habits, the page-turning trigger control can be designed as a right-to-left and / or left-to-right swiping operation, improving ease of use.

[0028] In one embodiment of this application, the preset touch mode is defined as either the number of times a character key is pressed within a preset time period reaches a preset number of times, or the duration of continuous pressing of a character key reaches a preset duration. The preset touch mode includes at least the following: The character keys are pressed a preset number of times within a preset time. The preset time is preferably 1 second to suit the operation speed of blind users and avoid missing the trigger opportunity due to reaction delay. The preset number of presses can be a double press (2 presses) or a triple press (3 presses), with an interval of ≤0.3 seconds between each press to ensure differentiation from "continuous input". For example, if you press the "1" key twice to input "1", the interval must be ≥0.5 seconds. Furthermore, a feedback mechanism can be introduced: when the preset number of presses is reached, the key triggers a "corresponding number of short vibrations" (e.g., a double press triggers 2 short vibrations, a triple press triggers 3 short vibrations), and the POS device's built-in buzzer emits a corresponding number of "beeps". There is no voice feedback to avoid leakage in public settings. In this way, whether it is "double-clicking within 1 second" or "long-pressing for 1.5 seconds", from the perspective of others, it is no different from "hesitation before normal input" or "temporary finger pause" - for example, if a blind person presses and holds the "1" key for 1.5 seconds to jump, others cannot judge whether it is "wanting to input '1' but not releasing" or "jumping"; if the "3" key is double-clicked to jump, others will mistakenly think that it is "accidentally pressing '3' twice", and it is impossible to associate the "jumping" behavior through the action, which poses a risk of privacy leakage.

[0029] In one embodiment of this application, the character key area 304 of each preset page number is different, including: dividing all password characters into at least two character groups according to preset classification rules; setting a one-to-one correspondence between the character groups and the character key area 304 of a single page; and dividing a touch screen area for each password character in the corresponding character group within the character key area 304. For example, commonly used characters for POS device payment passwords include "0-9 digits + X (commonly used for ID card passwords) + #, * (special verification characters)," totaling 13 characters. Based on the operating habits of blind people and the high-frequency need for password input, the character groups can be divided as follows: Character group A (odd numbers): 1, 3, 5, 7, 9 (5 characters). Character group B (even digits): 2, 4, 6, 8, 0 (5 characters).

[0030] Character group D (special characters): X, #, * (3 characters).

[0031] In this way, the number of characters in each group is controlled to 3-5, and the number of keys in the 304-key area of ​​a single page is moderate. For example, there are only 3 special characters on the 3rd page, avoiding the crowding problem of 10 keys on a traditional single page.

[0032] In one embodiment of this application, each character group contains at least three password characters. Preset prompting methods are set for the touchscreen areas corresponding to all password characters within the same character group. There are at least two different preset prompting methods among all touchscreen areas, and at least two touchscreen areas have the same preset prompting method. The different prompting methods within the same character group, such as "low-frequency vibration vs. high-frequency vibration" for character group A, allow blind people to quickly distinguish keys through a dual difference in "tactile + auditory" sensations. For example, when touching the "1" key (low-frequency vibration) and the "5" key (high-frequency vibration), even if the finger position is off, the difference in vibration frequency can promptly detect accidental touches. Furthermore, the voice segments in the preset prompting methods only contain categorization information such as "common" and "low-frequency," without specific numbers (e.g., instead of saying "1," only saying "common 1"). There is also no correlation between the beep tone and the vibration frequency; even if people around hear the beep or see the hand vibration, they cannot deduce the specific character.

[0033] In one embodiment of this application, a corresponding page prompting method is set for the character key area 304 of each page; after switching the character key area 304, the corresponding page prompting method is triggered according to the character key area 304 currently displayed on the touch screen of the target electronic device. For example, taking the input of the password "1 (page 1) → 2 (page 2) → 7 (page 3) → 0 (page 4)" by a blind person, the POS device defaults to displaying "1, 3, 5" on page 1. After powering on, the page prompting method for page 1 is triggered first (1 long vibration + 1 low beep). The blind person confirms that they are currently on page 1 through this prompt, and then touches the "1" key to complete the input; Switching to page 2: The blind person triggers the page jump by long-pressing the "1" key (pre-set touch method mentioned above). After the device completes the switch, the prompting method for page 2 is immediately triggered - the blind person feels "2 short vibrations" and hears "2 medium-tone short beeps", indicating that they have switched to page 4. Page 2: Then touch the "2" key to input; Switch to Page 3: The blind person jumps by double-clicking the "4" key on Page 2 (preset touch mode). After the page switch, the prompt on Page 3 is immediately triggered - "3 short vibrations + 3 high-pitched beeps". The blind person can quickly recognize "page 3" through high-frequency vibration and high-pitched beeps and can locate the "7" key input without having to fumble for the key layout; Switch to Page 4: The blind person jumps by long-pressing the "8" key on Page 3. After the page switch, the special prompt on Page 4 (mixed vibration + mixed beeps) is triggered. The blind person confirms that they are in the special character page by "vibrating on both sides at the same time", and then touches the "0" key to complete the last character input.

[0034] In one embodiment of this application, the page-turning trigger control is set in the character key area 304 or the function key area 306. For example... Figure 3 As shown, the target electronic device also has a display area 302 near the top of the touch screen. The display area 302 uses encrypted graphics to display the number of characters entered by the blind person.

[0035] In one embodiment of this application, a key layout instruction is obtained, and key layout feedback is initiated based on the instruction. This feedback is used to provide visually impaired users with information about the key layout of the currently displayed character key area 304 on the touchscreen input page 300. The initial interface of the POS device during the payment phase is the aforementioned page 1. At this time, a key layout instruction is provided, and the content of the character key area 304 and function key area 306 of the current touchscreen input page 300 is provided to the visually impaired user via voice broadcast or earphone transmission. This helps the visually impaired user quickly understand the content of the current page and improves input efficiency.

[0036] Please refer to Figure 2 Another embodiment of this application provides a payment processing method suitable for blind people, applied to a target electronic device, the method including steps 202-208: In step 202, the blind person's payment request is obtained.

[0037] For example, a voice receiving component can be used to interpret the voice commands of blind people, or a button can be provided to monitor the case status in real time to obtain payment requests from blind people.

[0038] In step 204, the aforementioned touchscreen input page 300 is invoked on the target electronic device based on the blind person's payment request.

[0039] The code generated by the touch screen input page 300 can be burned into the main control module of the target electronic device, or it can be obtained by the target electronic device from the remote service terminal based on the blind person's payment request, and can be updated and maintained online.

[0040] In step 206, in response to the touch of the page-turning trigger control, the character key area 304 is switched in the character key area 304 of the preset page number.

[0041] For example, when a blind person needs to switch from page 1 ("1, 3, 5") to page 2 ("2, 4, 6") when entering a password at a POS terminal, they only need to touch the page-turning trigger control with the "↓" Braille symbol on the right edge (triggered by a single-point press). The device will immediately switch the character key area 304 to page 2. The page-turning trigger control can take the form of a slider, a rotary button, etc., and is not limited here. In this way, blind people can operate accurately without sight, which not only improves the accuracy of operation, but also prevents others from seeing the complete password by turning pages.

[0042] In step 208, in response to a touch operation on the character key area 304, the POS device parses and obtains the string corresponding to the touch operation, and initiates payment based on the string. For example, in a shopping scenario, the POS device has completed scanning the product code, and the screen displays "Please enter payment password (6 digits), consumption amount 68 yuan". The default display is the first page of the character key area 304 ("1, 3, 5", odd number group). The blind person enters the 6-digit password step by step through the cycle of "touch operation (input / page turning) → page prompt confirmation → continue touch operation". The POS device parses the characters corresponding to each touch operation in real time to form a string. The string is immediately encrypted after parsing, and the payment information (password, amount) is not visually displayed or leaked. The payment security level meets the national financial device security standards.

[0043] Please refer to Figure 5 Another embodiment of this application provides an electronic device 500, including a memory 502, a processor 504, and a computer program stored in the memory 502 and running on the processor 504. When the processor 502 executes the computer program, it implements the various steps of the above-described input recognition method for the blind. The electronic device 500 can specifically be a mobile phone, tablet, computer, or other common device. A touchscreen input page is created on its touchscreen. This touchscreen input page includes a function key area, a page-turning trigger control, and a character key area whose area exceeds at least one-third of the entire touchscreen. The character key area has a preset number of pages, and each page displays different password characters. This reduces the pressure of arranging password characters in each character key area, allowing each character key area to provide a larger key area for the corresponding password characters, thereby improving the accuracy of the blind person's clicks on each character key. The IDE (Input Method Interface) also makes it difficult for others to completely obtain all the input content of the blind person through page-turning operations, ensuring the input security of the blind person.

[0044] Please refer to Figure 6 Another embodiment of this application provides an electronic device 700, including a memory 702, a processor 704, and a computer program stored in the memory 702 and running on the processor 704. When the processor 702 executes the computer program, it implements the various steps of the payment processing method for the blind described above. The electronic device 700 is generally a POS device in scenarios such as supermarkets, hotels, subways, and medical institutions. When a blind person performs a payment operation, a touch screen input page from the above-mentioned input recognition method for the blind is displayed on the touch screen, thereby improving the accuracy of the blind person's click on each character key. At the same time, the blind person can find the password character they want to enter by flipping through pages. During the payment stage of the target electronic device, in response to the touch screen operation in the character key area, the corresponding key is recognized and generated for payment verification.

[0045] In summary, this invention provides an input recognition method, a payment processing method, and an electronic device suitable for the blind. It creates a touchscreen input page on the target electronic device's touchscreen. This touchscreen input page includes a function key area, a page-turning trigger control, and a character key area exceeding one-third of the entire touchscreen. The character key area has a preset number of pages, with each page displaying different password characters. This reduces the pressure of arranging password characters in each character key area, allowing each character key area to provide a larger area for the corresponding password characters, thereby improving the accuracy of the blind person's clicks on each character key. By responding to the touch of the page-turning trigger control, the user can switch between the preset number of character key areas, using page-turning operations to find the desired password characters. This is achieved during the payment phase of the target electronic device. Responding to touchscreen operations on the character key area, it recognizes and generates corresponding keys for payment verification. The page-turning operation is less observable to others compared to traditional page-turning controls. Specifically, the jump operation is completely synchronized with the "touch of character keys," making it impossible for others to distinguish whether the blind person is inputting or turning pages. For example, if a blind person touches and holds the "1" key to jump, from another person's perspective, it only appears as "the finger is on the '1' key for 2 seconds," making it impossible to determine whether it's "hesitation before input" or "jumping operation." This avoids voice leakage in public settings, making it difficult for others to fully obtain the blind person's input, ensuring input security. Simultaneously, based on the currently displayed character key area on the target electronic device's touchscreen, it triggers corresponding page prompts to assist the blind person in confirming page content. Combined with the large key design on a single page, it reduces the probability of mis-inputting by the blind person and improves input efficiency.

[0046] The above are merely embodiments of the present invention and do not limit the patent scope of the present invention. Any equivalent modifications made based on the content of the present invention's specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of the present invention.
