Description
Technical Field
The present invention relates to the technical field of a password input device, and more particularly, to a password input method, which is executed by a processor of a password input device, so that a visually impaired person can perform a password input operation with high security on the password input device.
Background
Along with the progress of technology, various touch-control electronic devices are proposed to improve the convenience of life. Undoubtedly, in the case of the wide application of these touch-control electronic devices, the conventional electronic devices (such as the password input device) with physical keys are gradually eliminated and replaced by the corresponding touch-control electronic devices. It is noted that the password input device of the physical key is generally provided with braille characters (Braille character) on each key, so that the visually impaired can find the corresponding key and press by touching the braille characters. However, the touch screen of the touch electronic device is not provided with the braille character, so it is very difficult for the visually impaired to complete the password input on the touch screen.
In view of this, a touch-control electronic device suitable for visually impaired people has been proposed. In the process of inputting the password by the visually impaired person, the touch-control electronic device can send out a key prompt voice when the visually impaired person clicks the touch-control screen by the fingers of the visually impaired person, so that the visually impaired person can conveniently understand what key is clicked at present. It is easy to understand that in the process of inputting the password by the visually impaired person, the other person can know each word input by the visually impaired person only by listening to the key prompt voice sent by the touch-control electronic device, so that the whole group of passwords is known. In other words, the conventional touch-control electronic device suitable for visually impaired people has a disadvantage of low safety.
From the foregoing, it is apparent that there is still a need for improvement in touch-control electronic devices suitable for visually impaired people. In view of the above, the present invention was developed by the inventor to develop a password input method.

Detailed Description
In order to more clearly describe a password input method according to the present invention, a preferred embodiment of the present invention will be described in detail below with reference to the drawings.
Referring to fig. 1, a perspective view of a touch electronic device 1 applying a password input method of the present invention is shown. As shown in fig. 1, the touch electronic device 1 has a touch screen 11 and a microprocessor 12. In a possible embodiment, the touch-sensitive electronic device 1 may be a POS machine (Point-of-sale system), a smart phone, a tablet computer, an All-in-one computer, a notebook computer, an access control device, or an electronic door lock. According to the present invention, the microprocessor 12 performs the password input method of the present invention during a password input operation performed by a visually impaired person through the touch screen 11, so that the visually impaired person can successfully input a set of passwords into the touch-sensitive electronic device by performing multiple swipe operations, multiple slide operations and multiple key-in operations on the touch screen 11, and high security is maintained during the password input process.
Referring to fig. 2A and 2B, a flowchart of a password input method according to the present invention is shown. Referring to fig. 3A to 3E, a top view of the touch electronic device 1 is shown. As shown in fig. 1, 2A and 3A, the password input method of the present invention first executes step S1: after a finger 2 generates a touch position 21 on a touch screen 11 of the touch electronic device 1, it is confirmed that a virtual number key 5 is selected, and then the touch electronic device 1 is controlled to send out a prompt signal. In one embodiment, the prompt signal may be an audio signal. Of course, in other possible embodiments, the alert signal may be a vibration signal, an acoustic vibration composite signal, or a vibration-acoustic composite signal.
It should be noted that, as shown in fig. 3A (a), before executing the step S1, the microprocessor 12 firstly plans a first area 1R1 and a second area 1R2 within the first area 1R1 on the touch screen 11, and then controls the touch electronic device 1 to send a prompt signal to prompt a visually impaired person to start touching the touch screen 11 with his finger 2. In this way, as shown in fig. 3 (b), when executing the step S1, the microprocessor 12 will simultaneously confirm whether the strike position is within the second area range 1R2, and if yes, proceed to the step S2. If not, the touch electronic device 1 is controlled to send a prompt signal, and then the step S1 is repeatedly executed. In other words, if the striking position 21 generated by the finger 2 of the visually impaired person on the touch screen 11 does not fall within the second area range 1R2, the following visually impaired person is affected to perform a sliding operation on the touch screen 11 with the finger 2 to select another virtual number key different from the virtual number key 5. For this reason, when the touch position 21 is not within the second area 1R2, the microprocessor 12 controls the touch electronic device 1 to send a prompting signal (e.g. a sound signal) to prompt the visually impaired to adjust the touch position 21 to be within the second area 1R 2.
In an embodiment, when the touch position 21 falls within the first area 1R1 and is adjacent to a right boundary of the second area 1R2, the touch electronic device 1 prompts the visually impaired person to adjust the touch position 21 to the left by voice so as to fall within the second area 1R 2. Moreover, when the touch position 21 falls within the first area 1R1 and is adjacent to a lower boundary of the second area 1R2, the touch electronic device 1 prompts the visually impaired person to adjust the touch position 21 upwards by voice so as to fall within the second area 1R 2. On the other hand, when the touch position 21 falls within the first area 1R1 and is adjacent to a left boundary of the second area 1R2, the touch electronic device 1 prompts the visually impaired person to adjust the touch position 21 to the right by voice so as to fall within the second area 1R 2. Furthermore, when the touch position 21 falls within the first area 1R1 and is adjacent to an upper boundary of the second area 1R2, the touch electronic device 1 prompts the visually impaired person to adjust the touch position 21 downward by voice so as to fall within the second area 1R 2.
It should be noted that a conventional physical keyboard generally includes four rows of keys, the first row including a physical number key 1, a physical number key 2, and a physical number key 3, the second row including a physical number key 4, a physical number key 5, and a physical number key 6, the third row including a physical number key 7, a physical number key 8, and a physical number key 9, and the fourth row including a first physical function key (e.g., a cancel key), a physical number key 0, and a second physical function key (e.g., a confirm key). Moreover, another conventional physical keyboard generally includes four rows of keys, a first row including a physical number key 7, a physical number key 8 and a physical number key 9, a second row including a physical number key 4, a physical number key 5 and a physical number key 6, a third row including a physical number key 1, a physical number key 2 and a physical number key 3, and a fourth row including a first physical function key (e.g., a cancel key), a physical number key 0 and a second physical function key (e.g., a confirm key).
As shown in fig. 2A and 3B, the method flow then executes step S2: confirm whether the finger 2 is then performing a sliding operation on the touch screen 11. More specifically, after the touch position 21 is generated on the touch screen 11, the touch electronic device 1 uses a prompt signal (e.g., an audio signal) to remind the visually impaired person to perform a digital selection operation. For example, as shown in fig. 3B (a), when the visually impaired person slides upward on the touch screen 11 with his finger 2, the microprocessor 12 recognizes the sliding operation as "slide upward", and selects a virtual number key 2 or a virtual number key 8. At this time, as shown in the graph (B) in fig. 3B, as long as the finger 21 then performs a typing operation on the touch screen 11, the input of the number 2 or the number 8 can be completed. In one embodiment, the typing operation is to continuously touch the touch screen 11 twice. Of course, in other possible embodiments, the typing operation may be three consecutive strokes of the touch screen 11.
In other words, after determining the striking position 21 (i.e., completing the step S1), if the visually impaired person slides with his finger 2 on the touch screen 11 to the right as shown in the graph (a) of fig. 3C, the microprocessor 12 recognizes the sliding operation as "sliding to the right", and selects a virtual number key 6. At this time, as shown in the graph (b) in fig. 3C, as long as the finger 2 is then continuously clicking the touch screen 11 twice (i.e., performing the key-in operation), the input of the number 6 can be completed.
It can be inferred that after determining the striking position 21, as shown in the graph (a) in fig. 3D, if the visually impaired person slides down on the touch screen 11 with his finger 2, the microprocessor 12 recognizes the sliding operation as "sliding down", and selects a virtual number key 8 or a virtual number key 2. At this time, as shown in the graph (b) among the graphs shown in fig. 3D, as long as the finger 2 is then continuously clicking the touch screen 11 twice (i.e., performing the key-in operation), the input of the number 8 or the number 2 may be completed.
It can be further deduced that, after determining the striking position 21, as shown in the graph (a) of fig. 3E, if the visually impaired person slides with his finger 2 on the touch screen 11 to the left, the microprocessor 12 recognizes the sliding operation as "sliding to the left", so as to select a virtual number key 4. At this time, as shown in the graph (b) in fig. 3E, as long as the finger 2 is then continuously clicking the touch screen 11 twice (i.e., performing the key-in operation), the input of the number 4 can be completed.
As shown in fig. 2A, in the case where the determination result of this step S2 is Yes, the method flow proceeds to step S3: the touch electronic device 1 is controlled to send a prompt signal (e.g. sound signal), and then the above step S2 is repeatedly performed. After referring to fig. 3A to 3E, it should be understood that when the visually impaired person wants to input a number to the touch electronic device 1 by touching the touch screen 11, he or she must first generate a touch position 21 on the touch screen 11 falling within the second area range 1R2 by using the finger 2 (i.e. step S1), and then directly double-click the touch screen 11 to complete the input of the number 5. Alternatively, after the striking position 21 is generated, it is then slid upward, rightward, downward, or leftward on the touch screen 11, so that the virtual number key 1, 2, 3, 4, 5, 6, 7, 8, 9, or 0 is selected. After using the sliding operation to select another virtual number key that is different from the virtual number key 5, the visually impaired person may then double click directly on the touch screen 11 to effect input of the number represented by the virtual number key selected (i.e., 1, 2, 3, 4, 5, 6, 7, 8, 9, or 0).
Referring to fig. 3A to 3E, after the touch position 21 is generated, if the visually impaired person slides his finger 2 downward on the touch screen 11, the touch electronic device 1 will issue a voice prompt. Continuing, if the finger 2 slides down on the touch screen 11 again, the touch electronic device 1 will send out a voice prompt (voice prompt) again. At this point, a virtual number key 0 has been selected. In other words, if the number to be input by the visually impaired person is not 5 but 0, after the completion of step S1, the steps S2 and S3 must be repeated twice to select a virtual number key 0 through the sliding operation. Thus, as long as the finger 21 is then continuously clicking the touch screen 11 twice (i.e., performing the typing operation), the input of the number 0 can be completed.
After step S1 is completed to generate the touch position 21, if the visually impaired person then slides his finger 2 upwards on the touch screen 11, the touch-sensitive electronic device 1 will issue a voice prompt. Continuing, if the finger 2 slides on the touch screen 11 to the right, the touch electronic device 1 will send out a voice prompt again. At this time, a virtual number key 3 or a virtual number key 9 has been selected, so that the input of the number 3 or the number 9 can be completed as long as the finger 21 is then continuously clicking the touch screen 11 twice (i.e., performing the key-in operation).
More specifically, after the striking position 21 is generated, if the visually impaired person then slides his finger 2 upwards on the touch screen 11, the touch-sensitive electronic device 1 will issue a voice prompt. Continuing, if the finger 2 slides on the touch screen 11 to the left, the touch electronic device 1 will send out a voice prompt again. At this time, a virtual number key 1 or a virtual number key 7 has been selected, so that the input of the number 1 or the number 7 can be completed as long as the finger 2 is then continuously clicking the touch screen 11 twice (i.e., performing the typing operation).
As shown in fig. 3A to 3E, after the striking position 21 is generated, if the visually impaired person slides his finger 2 downward on the touch screen 11, the touch-sensitive electronic device 1 will send a voice prompt. Continuing, if the finger 2 slides on the touch screen 11 to the right, the touch electronic device 1 will send out a voice prompt again. At this time, a virtual number key 9 or a virtual number key 3 has been selected, so that the input of the number 9 or the number 3 can be completed as long as the finger 21 is then continuously clicking the touch screen 11 twice (i.e., performing the key-in operation).
More specifically, after the striking position 21 is generated, if the visually impaired person slides his finger 2 downward on the touch screen 11, the touch-sensitive electronic device 1 sends a voice prompt. Continuing, if the finger 2 slides on the touch screen 11 to the left, the touch electronic device 1 will send out a voice prompt again. At this time, a virtual number key 7 or a virtual number key 1 has been selected, so that the input of the number 7 or the number 1 can be completed as long as the finger 21 is then continuously clicking the touch screen 11 twice (i.e., performing the typing operation).
It should be noted that, in an embodiment, in the case where the first sliding operation is a downward sliding operation, the second sliding operation is a downward sliding operation, and the third sliding operation is a rightward sliding operation, a virtual confirm key, a virtual cancel key, or other specific function key is selected. In other words, the virtual confirm key or the virtual cancel key is preset to the right of the virtual number key 0. Thus, in another embodiment, a virtual cancel key or a virtual confirm key is selected in the case where the first sliding operation is a downward sliding, the second sliding operation is a downward sliding, and the third sliding operation is a leftward sliding. In other words, the virtual cancel key or the virtual confirm key is preset to the left of the virtual number key 0.
As can be seen from the above description, if the number to be input by the visually impaired person is not 5, the steps S2 and S3 are performed at least once. For example, in the case that the number to be input is 2, 4, 6, 8, steps S2 and S3 are performed once. In addition, in the case that the number to be input is 0, 1, 3, 7, 9, step S2 and step S3 are performed twice. On the other hand, in the case where a confirm command, a cancel command or other specific function command is to be input, steps S2 and S3 are performed three times.
As shown in fig. 2A, in the case where the determination result of this step S2 is "No (No)", it means that the visually impaired person has completed selection of one virtual number key by the sliding operation. At this time, the method flow then executes step S4: it is confirmed whether the finger 2 then performs a typing operation on the touch screen 11 (i.e., double-clicking the touch screen 11) to perform input of a number represented by the virtual number key selected. If the determination result in step S4 is "No (No)", the method flow then proceeds to step S5: after the finger 2 does not touch the touch screen 11 for a period of time, the touch electronic device 1 is controlled to send a prompt signal, and then the above step S1 is repeatedly performed. Conversely, in the case where the determination result of this step S4 is Yes, the method flow proceeds to step S6: the number input by completing the sliding operation and the typing operation is recorded, and the touch electronic device 1 is controlled to send out a prompt signal. Finally, the method flow then executes step S7: the foregoing steps S1 to S6 are repeatedly performed until a confirmation command or a cancel command is input via completion of the sliding operation and the key-in operation.
Fig. 4A to 4E show top views of the touch electronic device 1. For example, to input the password 5691 into the touch-sensitive electronic device 1 by the sliding operation and the typing operation, the visually impaired person first generates a touch position on the touch screen 11 with his finger 2 (as shown in the graph (a) of fig. 4A), and after receiving a voice prompt sent by the touch-sensitive electronic device 1, then double-clicks the touch screen 11 (as shown in the graph (b) of fig. 4A), so that the microprocessor 12 records the number 5 input by completing the sliding operation and the typing operation.
Continuously, after the touch electronic device 1 sends out a voice prompt, the visually impaired person again uses his finger 2 to generate a touch position on the touch screen 11 (as shown in the graph (a) in fig. 4B), and after receiving a voice prompt sent out by the touch electronic device 1, he/she slides his/her finger 2 on the touch screen 11 once to the right (as shown in the graph (B) in fig. 4B). Then, after the touch-sensitive electronic device 1 sends a voice prompt, the visually impaired person double-clicks the touch screen 11 with his finger 2 (as shown in the diagram (c) of fig. 4B), so that the microprocessor 12 records the number 6 entered by completing the sliding operation and the typing operation.
After the touch electronic device 1 sends a voice prompt, the visually impaired person again uses his finger 2 to generate a touch position on the touch screen 11 (as shown in fig. 4C, a diagram (a)), and after receiving a voice prompt sent by the touch electronic device 1, he slides his finger 2 on the touch screen 11 once (as shown in fig. 4C, a diagram (b)). Then, after the touch-sensitive electronic device 1 sends a voice prompt, the visually impaired person slides down on the touch screen 11 with his finger 2 once again (as shown in fig. 4C (b)). Then, after the touch-sensitive electronic device 1 sends a voice prompt, the touch screen 11 is double-clicked (as shown in the graph (C) in fig. 4C), so that the microprocessor 12 records the number 9 inputted by completing the sliding operation and the typing operation.
Continuously, after the touch electronic device 1 sends out a voice prompt, the visually impaired person again generates a touch position on the touch screen 11 with his finger 2 (as shown in the graph (a) of fig. 4D), and after receiving a voice prompt sent out by the touch electronic device 1, slides upwards on the touch screen 11 with his finger 2 once (as shown in the graph (b) of fig. 4D). Then, after the touch-sensitive electronic device 1 sends a voice prompt, the visually impaired person slides the finger 2 on the touch screen 11 once more (as shown in fig. 4D, b). Next, after the touch-sensitive electronic device 1 sends a voice prompt, the touch screen 11 is double-clicked (as shown in the graph (c) in fig. 4D), so that the microprocessor 12 records the number 1 inputted by completing the sliding operation and the typing operation.
After the four digits 5, 6, 9, 1 are input by the sliding operation and the typing operation, the touch-control electronic device 1 sends out a voice prompt, then the visually impaired person again uses his finger 2 to generate a touch position on the touch screen 11 (as shown in the graph (a) in fig. 4E), and after receiving a voice prompt sent out by the touch-control electronic device 1, slides with his finger 2 on the touch screen 11 once to the right and twice to the bottom (as shown in the graph (b) in fig. 4E). After each finger sliding is completed, the touch electronic device 1 sends out a voice prompt. Then, the visually impaired person double-clicks the touch screen 11 with his finger 2 (as shown in fig. 4E, c), so that the microprocessor 12 receives a confirmation command sent by the visually impaired person through the sliding operation and the typing operation, successfully inputs the password 5691 into the touch-sensitive electronic device 1, and high security is maintained during the password input process.
It should be noted that, in the process of inputting a password into the touch-sensitive electronic device 1, the method of the present invention only requires that the touch position 21 generated by each finger 2 touch (tap) on the touch screen 11 must fall within the second area range 1R2, and does not require that the four touch positions 21 of four touches be the same position. In addition, during a group of passwords is input into the touch electronic device 1, the visually impaired person can cancel the digits input previously after the finger 2 performs a back key typing operation on the touch screen 11. In one embodiment, the back key entry operation is three consecutive strokes of the touch screen 11. Of course, in other possible embodiments, the back key entry operation may be a continuous double-click of the touch screen 11. On the other hand, it should be understood that the first prompt signal, the second prompt signal, the third prompt signal, the fourth prompt signal, the fifth prompt signal, and the sixth prompt signal shown in fig. 2A refer to that the touch-sensitive electronic device 1 must issue a prompt signal after an operation of the finger 2 on the touch screen 11, so as to inform the visually impaired person to complete that a number has been selected, a selected number has been input, an input number has been eliminated, a password input operation has been completed, a password input operation has been canceled, etc. Thus, in one embodiment, the first alert signal, the second alert signal, the third alert signal, the fourth alert signal, the fifth alert signal, and the sixth alert signal are all any one selected from the group consisting of an audio signal, a vibration signal, an audio vibration composite signal, and a vibration-audio composite signal.
Thus, the foregoing has fully and clearly described a password input method of the present invention. It should be emphasized, however, that the foregoing disclosure is illustrative of the preferred embodiments, and that certain changes and modifications may be made therein without departing from the scope of the invention as defined by the appended claims.
