Referring to FIG. 1 and FIG. 2 at the same time, the following exemplarily describes in detail how the electronic device 1 of the present embodiment implements the one-dot mode operation method.

First, in step S1, the processing unit 15 determines whether the touch control unit 12 is subjected to a Braille mode activation operation indicating a plurality of touchable positions at the same time. More specifically, in this embodiment, preferably, once the processing unit 15 determines that the five touchable positions on the touch unit 12 are simultaneously subjected to a long-press touch operation, the processing unit 15 will It is determined that the touch control unit 12 is subjected to the Braille mode activation operation. In other words, according to this embodiment, the user only needs to use five fingers to simultaneously perform a long-pressing touch operation on any five touch points on the touch unit 12 , and then the processing unit 15 can be activated. It is determined that the touch control unit 12 is subjected to the Braille mode activation operation. However, in other embodiments, the Braille mode activation operation can also be implemented as other touch operations, such as clicking, double-clicking, dragging, or indicating different numbers of touchable positions, etc. This embodiment is limited.

If the judgment result of the processing unit 15 in step S1 is YES, the process proceeds to step S2 and step S6 at the same time; on the other hand, if the judgment result of the processing unit 15 in step S1 is NO, the processing unit 15 again Step S1 is performed.

In step S2 following step S1, when the processing unit 15 determines that the touch unit 12 is subjected to the Braille mode activation operation, the processing unit 15 outputs a setting prompt voice through the speaker unit 14, thereby The user is guided to perform the next operation on the touch unit 12 . In this embodiment, the setting prompt voice can be implemented as, for example, "Please use the index finger, middle finger and ring finger of the right hand to double-tap on the screen at the same time to set the input position", but it is not limited thereto. Next, the flow proceeds to step S3.

Referring to FIG. 3 , in step S3 , the processing unit 15 determines whether the touch unit 12 has received an input position setting operation indicating a plurality of operated positions 2 . More specifically, in this embodiment, preferably, once the processing unit 15 determines that the three operated positions 2 on the touch unit 12 are simultaneously subjected to a double-click touch operation, the processing unit 15 determines that The touch unit 12 is subjected to the input position setting operation, but not limited thereto. In other words, according to the present embodiment, the user only needs to use three fingers to simultaneously double-click any three touch points on the touch unit 12 to make the processing unit 15 determine It comes out that the touch unit 12 is subjected to the input position setting operation. However, in other embodiments, the processing unit 15 may also determine that the touch unit 12 is subject to the input position setting operation when determining that the manipulated positions 2 are touched one by one, instead of the present embodiment. limited.

If the judgment result of the processing unit 15 in step S3 is YES, the process proceeds to step S4, on the other hand, if the judgment result of the processing unit 15 in step S3 is NO, the processing unit 15 executes step S3 again.

In step S4 following step S3, once the processing unit 15 determines that the touch-control unit 12 is subjected to the input position setting operation, the processing unit 15 sets the touch-control unit 12 according to the three operated positions 2 respectively. on the three Braille input keys 3 (shown in Figure 3). Specifically, the three Braille input keys 3 are respectively three virtual keys set by the processing unit 15 on the touch control unit 12, and can be used by the user through the three virtual keys according to the Braille input rule Braille is input by pressing the keys, and the positions of the three Braille input keys 3 on the touch-control unit 12 respectively correspond to the three operated positions 2 in step S3 , for example. In addition, the three Braille input keys 3 are sequential to each other, and, in this embodiment, the order among the three Braille input keys 3 may be, for example, the processing unit 15 is operated according to the three Position 2 is set on the touch unit 12 in the order from left to right, but is not limited thereto.

After the processing unit 15 sets the three Braille input keys 3, the flow proceeds to step S5.

In step S5, the processing unit 15 determines whether the operation on the Braille input keys 3 indicates one of the Braille characters defined by the Braille input rule, and when the processing unit 15 according to the Braille input rule to determine that the operation received by the Braille input keys 3 indicates one of the target Braille characters of the Braille characters, the processing unit 15 generates the target Braille character, and convert the target Braille character into message data such as phonetic symbols, English letters or Arabic numerals corresponding to the target Braille character. In this way, the electronic device 1 can be used by visually impaired users to input various information through the Braille input keys 3 in a touch-sensitive manner.

In this embodiment, since the electronic device 1 is implemented as an ATM, the Braille input by the user through the Braille input keys 3 may represent, for example, a financial account password, a transfer account number, a transfer amount, and a deposit amount. , withdrawal amount, or any other information you need to enter when using the various service functions of the ATM. On the other hand, in the embodiment in which the electronic device 1 is implemented as a kiosk device or other self-service device, the Braille input by the user through the Braille input keys 3 may also represent, for example, name, telephone, address, The order product information, the purchase quantity, or any other information to be input into the kiosk device or the self-service device are not limited to this embodiment.

It is worth noting that, since each Braille character is composed of six dots, and the number of the Braille input keys 3 in this embodiment is three, therefore, the processing unit 15 is specially described below in step S5 The manner in which the target Braille character is generated is described in detail in .

Referring to FIG. 4 in conjunction with FIG. 1 and FIG. 2 , for the convenience of description, the three Braille input keys 3 are used as a first Braille input key 3A, a second Braille input key 3A shown in FIG. 4 , and a second Braille input key 3 respectively. An input key 3B and a third glyph input key 3C, and the first glyph input key 3A, the second glyph input key 3B and the third glyph input key 3C are collectively used as the 1-dot input of this embodiment unit 30. On the other hand, FIG. 4 also shows a Braille character 10 for illustration purposes, and, for convenience of description, a first dot p1, a second dot p2 and a second dot p2 on the left half of the Braille character 10 A third dot p3 is collectively used as a first part 101 of the Braille character 10, and a fourth dot p4, a fifth dot p5 and a sixth dot on the right half of the Braille character 10 p6 is collectively used as a second part 102 of the Braille character 10 .

In step S5 of this embodiment, the processing unit 15 determines whether the two operations received by the Braille input unit 30 indicate the Braille according to the two operations before and after the Braille input unit 30 . Enter one of the Braille characters defined by the rule (ie, whether the target Braille character is indicated).

Referring to FIG. 4 and FIG. 5 together with FIG. 1 , in more detail, taking the Braille character 10 as an example, step S5 of this embodiment includes the following sub-steps shown in FIG. 5 .

First, in sub-step S51, when the processing unit 15 determines that the Braille input unit 30 is operated for the first time, the processing unit 15 generates the Braille according to the first operation received by the Braille input unit 30 First part 101 of character 10. More specifically, in sub-step S51, the first Braille input key 3A corresponds to the first point p1, for example, the second Braille input key 3B corresponds to the second point p2, and the first Braille input key 3B corresponds to the second point p2. The three-dot character input key 3C corresponds to the third dot p3, for example. Therefore, if the user wants to express the first point p1 and the second point p2 as “raised” (shown in black in FIG. 4 ), and make the third point p3 express as “not raised” ” (indicated in white in Figure 4), then you only need to use two fingers to simultaneously perform a single-click touch operation on the first Braille input key 3A and the second Braille input key 3B at the same time. The processing unit 15 is made to generate the first part 101 as shown in FIG. 4 .

After the processing unit 15 generates the first part 101, the sub-step S52 is performed.

In sub-step S52 , the processing unit 15 outputs an input prompt voice through the speaker unit 14 to prompt the user to continue inputting the second part 102 of the Braille character 10 through the Braille input unit 30 . In this embodiment, the input prompt voice can be implemented as "please continue to input the second half of Braille", for example. And, preferably, the processing unit 15 can, for example, output the input prompt voice only when it is determined that the accumulated time that the Braille input unit 30 has not been subjected to the second operation reaches a predetermined length of time (for example, 3 seconds). However, if the processing unit 15 determines that the Braille input unit 30 is operated for the second time before the predetermined time period is reached, the input prompt voice is not output. In addition, in other embodiments, the sub-step S52 may also be omitted, which is not limited to this embodiment. Next, sub-step S53 is performed.

In sub-step S53, when the processing unit 15 determines that the Braille input unit 30 is subjected to the second operation, the processing unit 15 generates the Braille character according to the second operation received by the Braille input unit 30 Second part 102 of 10. Different from sub-step S51, in sub-step S53, the first braille input key 3A corresponds to the fourth point p4, for example, the second braille input key 3B corresponds to the fifth point p5, for example, The third dot input key 3C corresponds to the sixth dot p6, for example. Therefore, if the user wants to express the fourth point p4 as "raised" and the fifth point p5 and the sixth point p6 as "not raised", he only needs to use one finger to express A single-click touch operation on the first Braille input key 3A can cause the processing unit 15 to generate the second part 102 as shown in FIG. 4 .

After the processing unit 15 generates the second part 102, the sub-step S54 is performed.

In sub-step S54, the processing unit 15 combines the first part 101 and the second part 102, and judges whether the combination result of the first part 101 and the second part 102 is the same as that defined by the Braille input rule. One of the Braille characters matches, and if the judgment result is yes, the processing unit 15 determines that the operation received by the Braille input keys 3 indicates the target Braille character, and if the judgment result is No , the processing unit 15 determines that the operations on the Braille input keys 3 do not indicate any target Braille characters. In this case, the processing unit 15 can output voice through the speaker unit 14 to Prompt the user for input errors.

In step S6 following step S1, the processing unit 15 controls the photographing unit 13 to perform photographing, so as to obtain an image data from the photographing unit 13, and the image data is, for example, the photographing unit 13 in this embodiment. Dynamic video produced by real-time recording. Moreover, when the processing unit 15 determines that there are two or more human bodies in the shooting range of the photographing unit 13 according to the image data, a warning voice is output through the speaker unit 14 to remind the user whether to pay attention to whether Someone is watching the operation of the touch unit 12 . It should be added that the processing unit 15 may, for example, use a human body recognition model trained by machine learning and pre-stored in the storage unit 11 to recognize the image data, but not limited to this, and , in other embodiments, the braille mode operation method may not include step S6, but is not limited to this embodiment.

The above is the Braille mode operation method implemented by the electronic device 1 of the present embodiment.

As described above, in this embodiment, once the processing unit 15 determines in step S3 that the touch unit 12 is subjected to the input position setting operation, it will in step S4 according to the input position setting operation to indicate the The three operated positions 2 are respectively set to the three Braille input keys 3 . It is worth noting that most ATMs, kiosk equipment or self-service equipment are designed to be floor-standing, and cannot be held by users like portable electronic devices. Therefore, how to make visually impaired The relative position between the user's hand and the touch unit 12 can be easily maintained by the user, which becomes an important consideration in the design of the electronic device 1 of this embodiment. One of the effects of the present embodiment is that: since the number of the Braille input keys 3 is three, the electronic device 1 allows the user to input Braille with only one hand. In the implementation mode that requires simultaneous operation with both hands, this embodiment helps visually impaired users to maintain the relative position between their hands and the touch unit 12 more easily, so that the user can use the touch When the control unit 12 inputs Braille (ie, the aforementioned step S5 ), it can more easily and correctly click on the positions of the Braille input keys 3 , which is beneficial to the success rate of the operation.

In addition, in step S3 of this embodiment, the user needs to double-click any three points on the touch unit 12 "simultaneously" with three fingers, so that the processing unit 15 can determine the touch unit 12 is subjected to the input position setting operation. Therefore, the present embodiment is beneficial to allow the user to double-click the touch unit 12 by placing three fingers into a more comfortable and comfortable hand posture, so as to complete the setting operation of the input position of the touch unit 12 . As a result, since the positions of the three Braille input keys 3 are consistent with the three operated positions 2, the user can continue to maintain his comfortable and comfortable hand posture to input Braille in step S5, while the It is beneficial to the user's comfort and convenience of operation.

In addition, on the other hand of step S3 of this embodiment, the processing unit 15 only determines that the touch unit 12 is subjected to the input position setting operation when it determines that the three operated positions 2 are simultaneously “double-clicked”. Therefore, the present embodiment helps to avoid the user's erroneous touch on the touch unit 12 being determined as the input position setting operation, which is beneficial to the smoothness of the user's operation.

It is added that, in another embodiment, the processing unit 15 may determine the touch unit only when it determines that the six operated positions on the touch unit 12 are simultaneously touched in step S3. 12 is subjected to the input position setting operation, and, in step S4 of another embodiment, the processing unit 15 sets six Braille input keys on the touch unit 12 according to the six operated positions. In this way, in the step S5 of the other embodiment, the user can use three fingers of each hand (that is, a total of six fingers) to input Braille at the same time. An aspect of using both hands to enter Braille can also be implemented.

To sum up, by implementing the braille mode operation method, the processing unit 15 can respectively set the braille inputs on the touch unit 12 according to the operated positions 2 indicated by the input position setting operation key 3, and according to the Braille input rule, it is judged whether the operation of the Braille input keys 3 indicates the target Braille character, so that the electronic device 1 can be used by visually impaired users to touch Braille characters are input, thereby overcoming the inconvenience of the prior art, so the object of the present invention can indeed be achieved.

However, the above are only examples of the present invention, and should not limit the scope of the present invention. Any simple equivalent changes and modifications made according to the scope of the application for patent of the present invention and the content of the patent specification are still within the scope of the present invention. within the scope of the invention patent.
