The present invention provides a braille input method applied to a terminal, which includes, in a first embodiment thereof, referring to fig. 2:
step S10, if the awakening operation of the current touch screen is detected, voice guidance is output to guide a user to enter a Braille input mode;
if the terminal detects the awakening operation of the current touch screen, the terminal can output voice guidance to guide the user to enter the Braille input mode based on the form of the earphone device, and can also output voice guidance to guide the user to enter the Braille input mode in an external mode, wherein the output feedback mode of the touch screen is not specifically limited. The terminal may be a security device, and may also be other types of mobile terminals or fixed terminals, where the device type of the terminal is not specifically limited herein. The wake-up operation may be, but is not limited to, pressing a power-on key or a volume key of the terminal. In this embodiment, if the current terminal is used by the blind, the blind needs to wake up the touch screen of the current terminal before entering the braille input mode, and when the wake-up operation is successful, the blind is guided to enter the braille input mode by voice based on the earphone device. For example, based on the headphone device, a "please input a circle into braille input mode" is reported to the blind person in voice.
And step S20, entering a Braille input mode if the matching of the starting input operation and the operation parameters indicated in the voice guidance is detected.
And if the terminal detects that the starting input operation is matched with the operation parameters indicated in the voice guidance, entering a Braille input mode, and if the terminal detects that the starting input operation is not matched with the operation parameters indicated in the voice guidance, not entering the Braille input mode. The starting input operation refers to the operation of inputting a corresponding starting braille input mode on the touch screen by the blind person. For example, the operation indicated in the voice guidance is "please input a circle", and if it is detected that a circle is drawn corresponding to the user's start input operation, the braille input mode is entered.
According to the Braille input method provided by the embodiment of the invention, if the awakening operation of the current touch screen is detected, voice guidance is output to guide a user to enter a Braille input mode based on the earphone equipment; and if the detected starting input operation is not matched with the operation parameters indicated in the voice guidance, the Braille input mode is not entered. Therefore, the blind person can perform corresponding starting input operation through voice guidance, so that the blind person can conveniently enter a Braille input mode, and the user experience is improved.
Based on the first embodiment, a second embodiment of the method of the present invention is provided, in this embodiment, the step S10 may specifically include the following steps:
and S11, storing the preset operation symbol in a preset storage position, and prompting a user to input the preset operation symbol on the touch screen by voice.
The terminal stores the preset operation symbol in a preset storage position and prompts a user to input the preset operation symbol on the touch screen through voice. In this embodiment, when the wake-up operation on the current touch screen is detected, the preset operation symbol is called from the preset storage location, and the user is prompted by voice to input the preset operation symbol on the touch screen.
Based on the first embodiment, a third embodiment of the method of the present invention is provided, in this embodiment, the step S20 includes:
step S21, when detecting that a user triggers a motion gesture based on the starting input operation of voice guide input, acquiring a motion track triggered by the motion gesture on a touch screen;
and S22, entering a Braille input mode if the motion track is matched with a preset motion operation track associated with the voice guidance.
The method comprises the steps that when a terminal detects that a user triggers a motion gesture based on starting input operation of voice guidance input, a motion track triggered by the motion gesture on a touch screen is obtained, if the motion track is matched with a preset motion operation track associated with voice guidance, a Braille input mode is entered, and if the motion track is not matched with the preset motion operation track associated with the voice guidance, the Braille input mode is not entered. Wherein the motion trajectory may be a swing trajectory of the terminal. For example, the user enters the braille input mode by shaking both terminals and matching the preset movement operation trajectory associated with the voice guidance.
Based on the first embodiment, a fourth embodiment of the method of the present invention is provided, in this embodiment, the step S20 further includes:
step S23, when detecting that the user triggers the sliding track based on the starting input operation of the voice guide input, acquiring the symbol operation triggered by the sliding track on the touch screen;
and step S24, entering a Braille input mode if the symbol operation is matched with a preset operation symbol associated with the voice guidance.
When detecting that a user triggers a sliding track based on the starting input operation of voice guide input, the terminal acquires the symbol operation triggered by the sliding track on the touch screen; and entering a Braille input mode if the symbol operation is matched with a preset operation symbol associated with the voice guidance. The symbol operation means an operation that a user can input a character, a pattern, or a character on the touch panel, and the preset operation symbol may be set to "o". For example, when the symbol operation input by the user is one "∘", and the symbol operation input by the user matches the preset operation symbol, the braille input mode is entered.
In the embodiment, when detecting that a user triggers a sliding track based on the starting input operation of voice guidance input, the terminal acquires the symbol operation triggered by the sliding track on the touch screen; if the symbol operation is matched with the preset operation symbol associated with the voice guidance, entering a Braille input mode, and if the symbol operation is not matched with the preset operation symbol associated with the voice guidance, not entering the Braille input mode, and prompting input errors to re-input. Therefore, the Braille input mode is entered through the matching of the symbol operation and the preset operation symbol associated with the voice guidance, the false triggering is avoided, and the recognition rate is improved.
Based on the first embodiment, a fifth embodiment of the method of the present invention is provided, in this embodiment, step S24 may specifically include the following steps:
step S241, calculating the similarity between the symbol operation and a preset operation symbol;
in step S242, if the similarity between the symbol operation and the preset operation symbol is greater than or equal to the preset value, the symbol operation is matched with the preset operation symbol, and the braille input mode is entered.
And the terminal calculates the similarity between the symbol operation and the preset operation symbol, enters a Braille input mode if the symbol operation is matched with the preset operation symbol, and does not match with the preset operation symbol and does not enter the Braille input mode if the symbol operation is not matched with the preset operation symbol. For example, when the user inputs ". Smallcircle", there may be a point of irregularity, and the similarity between the calculation symbol operation and the preset operation symbol is greater than or equal to 80%, the braille input mode is entered.
A sixth embodiment of the method of the present invention is proposed based on the first embodiment, and in this embodiment, after step S242, the method includes:
step A, outputting vibration feedback if a first touch operation corresponding to a current touch screen is detected, and judging whether a second touch operation is detected within a preset time;
in this embodiment, understandably, when the touch screen input mode of the current device is the braille input mode, the touch area of the current touch screen is increased, the blind inputs a password by clicking or pressing the touch screen of the current device, when the blind performs the click or pressing touch operation on the current touch screen, based on the touch chip under the current touch screen, the touch chip senses the touch operation and simultaneously generates a corresponding touch signal to be transmitted to the device, the device receives the touch signal of the touch operation on the current touch screen, that is, the device detects the first touch operation corresponding to the current touch screen and outputs vibration feedback, and understandably, because the operating user of the current device is the blind, in the braille input mode, if the current touch operation is the click touch operation, the device detects the click operation corresponding to the current touch screen each time, and feeds back the click input effectiveness in a vibration manner to prompt the blind device to receive the click input operation.
And then, judging whether a second touch operation is detected within preset time, wherein the preset time can be flexibly set, such as 1 second, understandably, the braille dot matrix array is composed of one or more braille points, when a plurality of touch points corresponding to a plurality of touch operations corresponding to the current touch screen are detected, in order to facilitate the identification of the braille dot matrix array corresponding to the plurality of touch points, optionally, distinguishing whether the touch operation corresponding to one braille dot matrix array is finished based on the operation time interval of two adjacent touch operations, optionally, before the user inputs, outputting a voice prompt message of' please control to input the input time interval of two adjacent braille points in one braille dot matrix array for less than 1 second, inputting the next braille dot matrix array after 1 second of the one braille dot matrix is input, such as 1 second, then obtaining the touch point coordinate and the touch time of the first touch operation corresponding to the current touch screen, and judging whether the second touch operation is detected within 1 second.
B, if a second touch operation is not detected within preset time, acquiring a first Braille dot matrix array corresponding to the first touch operation;
in this embodiment, it can be understood that if the second touch operation is not detected within the preset time, the touch point corresponding to the first touch operation is the last touch point of the current first braille dot matrix array, and the corresponding first braille dot matrix array is generated based on the touch point corresponding to the first touch operation and the touch point within the preset time interval of the touch operation of the two adjacent touch points obtained after the adjacent previous braille dot matrix array is obtained. Or acquiring touch time of a touch point before the touch point corresponding to the first touch operation, and if it is detected that the touch time interval between two adjacent touch points before the touch point corresponding to the first touch operation exceeds the preset time, generating a first dot matrix braille array corresponding to the first touch operation based on a touch point after the touch point exceeds the preset time in the two adjacent touch points exceeding the preset time, a touch point corresponding to the first touch operation, and a touch point between a touch point after the touch point exceeds the preset time in the two adjacent touch points exceeding the preset time and the touch point corresponding to the first touch operation, wherein understandably, the touch point before the touch point exceeds the preset time in the two adjacent touch points exceeding the preset time is the last touch point in the adjacent last dot matrix array.
Optionally, if the touch screen is a capacitive touch screen, sensing units including driving electrodes and sensing electrodes are distributed on the capacitive touch screen, and mutual capacitance is formed between the driving electrodes and the sensing electrodes, so that the capacitive touch screen can be used for more accurately positioning the position of a touch point corresponding to touch operation. For example, if the driving electrodes are arranged in the transverse direction and the sensing electrodes are arranged in the longitudinal direction, the driving electrodes and the sensing electrodes are designed into a gradual-changing pattern, so that mutual capacitance between the two electrodes changes in a gradient manner along a preset transverse direction, and thus when a touch operation is detected, the change amount of the mutual capacitance also changes along the transverse direction and corresponds to the positions in the transverse direction one by one, and therefore, as long as the change amount is detected when the touch operation exists, the coordinates of a touch point can be determined.
And C, acquiring the Braille codes matched with the first Braille dot matrix array, and outputting voice feedback messages corresponding to the Braille codes.
In this embodiment, it can be understood that, after the first braille dot matrix array is obtained, the touch point set corresponding to the first braille dot matrix array is identified, specifically, a touch point coordinate set corresponding to the first braille dot matrix array is obtained, then, a numerical value set of a sum of horizontal and vertical coordinates corresponding to the touch point coordinate set is calculated, then, a target touch point corresponding to a minimum numerical value in the numerical value set of the sum of horizontal and vertical coordinates is determined, the target touch point is set as a coordinate origin, a position relationship between each touch point in the touch point coordinate set and the coordinate origin is determined, a braille dot matrix map matched with the first braille dot matrix array is determined according to the position relationship, finally, a braille code corresponding to the braille dot matrix map is obtained, then, a voice feedback message corresponding to the braille code can be output based on an earphone device in communication connection with the current device, specifically, for example, if the braille dot matrix map corresponding to the braille dot matrix map is obtained as "2", then, a voice broadcast "currently input password input by an earphone loudspeaker".
In this embodiment, through detecting the first touch operation that current touch-control screen corresponds, then output vibrations feedback to judge whether detect the second touch operation in the time of predetermineeing, if do not detect the second touch operation in the time of predetermineeing, then acquire the first braille dot matrix array that first touch operation corresponds, acquire the braille code that first braille dot matrix array matches after that, output with the pronunciation feedback message that the braille code corresponds, realized that the blind person can normally use the high touch-sensitive screen password keyboard of security, and through the pronunciation feedback message that the earphone output corresponds, the input security is better, and then has improved user's experience.
Further, after the step of determining whether the second touch operation is detected within the preset time, the method includes:
step A1, if the second touch operation is detected within the preset time, taking the second touch operation as the first touch operation, continuing to execute output vibration feedback, and judging whether the second touch operation is detected within the preset time.
And if a second touch operation is detected within a preset time, taking the second touch operation as the first touch operation, continuing to execute output vibration feedback, and judging whether the second touch operation is detected within the preset time.
In this step, it can be understood that, if the second touch operation is detected within the preset time, that is, the current first braille dot matrix array of the user has not been input completely, a touch point corresponding to the second touch operation is obtained, the second touch operation is taken as the first touch operation, the step of outputting vibration feedback is continuously executed, and whether the second touch operation is detected within the preset time is determined, wherein the specific subsequent steps are the same as the step S200 described above, and are not described herein again. And then, obtaining a first braille dot matrix array corresponding to the first touch operation until the next second touch operation is not detected within the preset time, wherein the step of obtaining the first braille dot matrix array corresponding to the first touch operation is the same as the step of obtaining the first braille dot matrix array, which is not repeated herein.
