The braille input method comprises the following steps:
step S100, if a first touch operation corresponding to the current touch screen is detected, outputting vibration feedback, and judging whether a second touch operation is detected within a first preset time;
in this embodiment, it may be understood that, if the object of use of the current device is a blind person, the touch screen input mode of the current device is a braille input mode, optionally, when the touch screen input mode of the current device is a braille input mode, a touch area of the current touch screen is increased, the blind person inputs a password in an international braille lattice manner by clicking or pressing the touch screen of the current device, where the touch screen may be a resistive touch screen, a capacitive touch screen, a vector pressure touch screen, or the like, specifically without limitation, when the blind person performs clicking or pressing touch operation on the current touch screen, based on a touch chip under the current touch screen, the touch chip senses the touch operation and generates a corresponding touch signal at the same time, the touch signal is transmitted to the device, the device receives the touch signal of the touch operation on the current touch screen, that is detected by the device to be the first touch operation corresponding to the current touch screen, and vibration feedback is output.
And then judging whether a second touch operation is detected within a first preset time, wherein the first preset time can be flexibly set, for example, 1 second, and understandably, the braille lattice array is formed by one or more braille points, when a corresponding plurality of touch points of a plurality of touch operations corresponding to a current touch screen are detected, in order to conveniently identify the braille lattice array corresponding to the plurality of touch points, optionally, distinguishing whether the touch operation corresponding to one braille lattice array is finished or not based on the operation time interval of two adjacent touch operations, optionally, outputting a voice prompt message of' please control input of two adjacent braille points in one braille lattice array is less than 1 second before user input, inputting the next braille lattice array after 1 second of inputting one braille lattice array, for example, 1 second, then acquiring the coordinates of the touch points 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.
Step S200, if the second touch operation is not detected within the first preset time, a first Braille lattice array corresponding to the first touch operation is obtained;
In this embodiment, it can be understood that if the second touch operation is not detected within the first preset time, the touch point corresponding to the first touch operation is the last touch point input to the current first braille lattice array, and the corresponding first braille lattice array is generated based on the touch point corresponding to the first touch operation and the touch point of the time interval of the touch operation of the two adjacent touch points acquired after the adjacent previous braille lattice array is acquired within the first preset time. Or acquiring the touch time of the touch point before the touch point corresponding to the first touch operation, and if the touch time interval between two adjacent touch points before the touch point corresponding to the first touch operation is detected to exceed the first preset time, generating a first braille lattice array corresponding to the first touch operation based on the touch point after the preset time in the two adjacent touch points exceeding the first preset time, the touch point corresponding to the first touch operation and the touch point between the touch point after the preset time in the two adjacent touch points exceeding the first preset time and the touch point corresponding to the first touch operation, wherein understandably, the touch point before the preset time in the two adjacent touch points exceeding the first preset time is the last touch point in the adjacent braille lattice array.
Optionally, if the touch screen is a capacitive touch screen, sensing units including a driving electrode and a sensing electrode are distributed on the capacitive touch screen, mutual capacitance is formed between the driving electrode and the sensing electrode, and the mutual capacitance can be used for more accurately positioning a touch point position corresponding to a touch operation. For example, if the transverse direction is a driving electrode and the longitudinal direction is an induction electrode, the driving electrode and the design are in a gradual change pattern, so that mutual capacitance between the two electrodes is changed in a gradient manner along a preset transverse direction, and when touch operation is detected, the change amount of the mutual capacitance is also changed along the transverse direction and corresponds to the position of 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.
Further, step S100 is followed by step S110
And if the second touch operation is detected within the first preset time, taking the second touch operation as the first touch operation, continuously executing output vibration feedback, and judging whether the second touch operation is detected within the first preset time.
In this step, it can be understood that if the second touch operation is detected within the first preset time, that is, the current first braille lattice array of the user is not yet input, the touch point corresponding to the second touch operation is obtained, the second touch operation is used as the first touch operation, the output vibration feedback is continuously performed, and whether the second touch operation is detected within the first preset time is determined, wherein the specific subsequent step is the same as the step S200 described above, and is not described herein. Then, until the next second touch operation is not detected within the first preset time, a first braille lattice array corresponding to the first touch operation is obtained, wherein the step of obtaining the first braille lattice array corresponding to the first touch operation is the same as the step of obtaining the first braille lattice array, and is not described herein.
Step S300, the braille codes matched with the first braille lattice array are obtained, and based on the earphone equipment, a first voice feedback message corresponding to the braille codes is output.
In this embodiment, it may be understood that after the first braille lattice array is acquired, a touch point set corresponding to the first braille lattice array is identified, specifically, a touch point coordinate set corresponding to the first braille lattice array is acquired, then a numerical value set of sum of abscissas and ordinates corresponding to the touch point coordinate set is calculated, then a target touch point corresponding to a minimum numerical value in the sum of abscissas and ordinates is determined, the target touch point is set as a coordinate origin, a positional relationship between each touch point in the touch point coordinate set and the coordinate origin is determined, a braille bitmap matched with the first braille lattice array is determined according to the positional relationship, finally, a braille code corresponding to the braille bitmap is acquired, then a voice feedback message corresponding to the braille code is output based on an earphone device in communication connection with the current device, specifically, for example, if the braille code corresponding to the braille bitmap is acquired as "2", the password currently input through the earphone loudspeaker is 2".
In this embodiment, if the first touch operation corresponding to the current touch screen is detected, vibration feedback is output, whether the second touch operation is detected in a first preset time is judged, if the second touch operation is not detected in the first preset time, a first braille lattice array corresponding to the first touch operation is obtained, then a braille code matched with the first braille lattice array is obtained, and based on earphone equipment, a voice feedback message corresponding to the braille code is output, so that the touch screen password keyboard with high safety can be normally used by the blind person, and the corresponding voice feedback message is output through the earphone, so that confidentiality is better when braille is input, and further user experience is improved.

step S112, determining a braille lattice diagram matched with the first braille lattice array based on the touch point coordinate set;
and step S113, acquiring the braille codes matched with the braille bitmap.
In this embodiment, a coordinate set of touch points corresponding to a first braille lattice array is obtained, where it can be understood that, if no other touch operation is detected in a time period before the first touch operation and after the previous braille lattice array is obtained, the braille lattice array corresponding to the first touch operation includes a touch point, if a plurality of touch operations with a time interval not exceeding a first preset time are detected in a time period before the first touch operation and after the previous braille lattice array is obtained, the braille lattice array corresponding to the first touch operation includes a plurality of touch points, then, based on a coordinate set of the touch points, a braille lattice map matched with the first braille lattice array is determined, optionally, after the first braille lattice array is obtained, an optimization process is performed on the touch points of the first braille lattice array, if the detected first braille lattice array may include a plurality of touch operations with a time interval not exceeding a first preset time, a preset pressure is obtained on the current braille lattice array, and if the touch values of the first braille lattice array are not matched with each other touch points, and if the touch values of the first braille lattice array are not matched with each other touch point are obtained, the touch point is determined. And then, after the optimized touch point is obtained, obtaining an international braille bitmap matched with the optimized first braille lattice array, and finally, obtaining a braille code corresponding to the braille bitmap.
Specifically, step S112 includes,
step S114, calculating the numerical value of the sum of the horizontal coordinates and the vertical coordinates corresponding to each touch point coordinate in the touch point coordinate set;
step S115, determining a target touch point corresponding to the minimum value in the sum of the horizontal coordinates and the vertical coordinates corresponding to the touch point coordinate set;
step S116, setting the target touch point as a coordinate origin, and determining the position relationship between each touch point in the touch point coordinate set and the coordinate origin;
step S117, determining a Braille lattice diagram matched with the first Braille lattice array according to the position relation.
In the step, after the optimized touch points corresponding to the first braille lattice array are obtained, the sum of the horizontal coordinates and the vertical coordinates corresponding to each touch point of the first braille lattice array is calculated, the target touch point with the smallest numerical value in the sum of the horizontal coordinates and the vertical coordinates corresponding to the touch point coordinate set is determined, then the target touch point is regarded as the coordinate origin, the coordinate position of each touch point is redetermined, the position relation between each touch point in the first braille lattice array and the coordinate origin is determined, and then the braille lattice map matched with the first braille lattice array is confirmed based on the position relation between each braille point in the braille lattice map.
According to the embodiment, the coordinate set of the touch points corresponding to the first Braille array is obtained, wherein the first Braille array comprises one touch point or a plurality of touch points, then the Braille array map matched with the first Braille array is determined based on the coordinate set of the touch points, and finally the Braille codes matched with the Braille array map are obtained, so that the accuracy of identifying the Braille array during Braille input is improved, the touch screen password keyboard with high normal use safety for the blind is realized, and the user experience is further improved.
