Executing step S101 chooses operation to be monitored in safety keyboard region.
Optionally, when determine safety keyboard read aloud that switch is in the open state or the terminal system to be currently running vision auxiliary
After assistant engineer's tool, this method can also include:
The safety keyboard tutorial message prestored is exported, the safety keyboard tutorial message is used to indicate user and carries out safety-key
Disk chooses operation.
Specifically, user may have several situations when opening safety keyboard, it is normal users that a kind of situation, which is user, is not made
The data of non-security keyboard area are read out with any reading screen software, in this case, user may not know safety
Keyboard reads aloud the effect of switch and how should operate and use safety keyboard after opening the switch；Another situation is that user
To there is the user of certain dysopia, terminal system is currently running vision auxiliary tool before opening safety keyboard, in this feelings
Under condition, read in the operation and payment application of screen software for the operation of safety keyboard may it is identical may also be different, user may
The operation read in screen software can be continued to use, but may be invalid or same operation refers in the safety keyboard region of payment application
Enable what is executed to be different operation.In this way, user is not because know that safety keyboard reads aloud effect or the safety keyboard behaviour of switch
The application method of work and maloperation, therefore can first prestore safety keyboard operation guidance information are detecting that safety keyboard reads aloud
It when switch is turned on, is exported to user, chooses operation to prompt user to carry out safety keyboard.
Wherein, safety keyboard operation guidance information is the use for choosing operation for safety keyboard region in payment application
Guidance, the safety keyboard operation guidance information can be text, video data or voice data etc..Specifically, if safety-key
Disk operation guidance information is text, then when detecting that safety keyboard is read aloud switch and is turned on, is shown with written form in correlation
In interface, if at this moment user does not open reading screen software, oneself it can read, if at this moment user opens reading screen software,
The word content for then reading the screen available safety keyboard operation guidance information of software is then converted into voice output, prompts view
Feel how impedient people carries out safety keyboard choosing operation.If safety keyboard operation guidance information is voice data or video
Data obtain the voice data or video prestored then when detecting that safety keyboard is read aloud switch and is turned on from database
It is exported after data.
It is further alternative, instruction is switched on when terminal receives to read aloud for safety keyboard, safety keyboard is bright
It reads switch and is labeled as open state.Wherein, open command can be the operation such as click, sliding, shaking, not limit specifically here
It is fixed.When terminal detect read aloud for safety keyboard switch on instruction when, then safety keyboard is read aloud into switch labeled as opening
State is opened, so as to determine whether safety keyboard reads aloud switch in the open state according to the label.
Step S102 obtains the content of text of the target key, calls the text-to-speech engine in terminal system will
The content of text of the target key is converted to voice data.
After target key has been determined, the payment application of terminal obtains the content of text of the target key, passes through calling
Text-to-speech engine in terminal system, i.e. TTS (Text To Speech, text-to-speech technology) is by the text of target key
This Content Transformation is at voice data.For example, as shown in figure 5, if the target key currently chosen is " Del ", i.e. delete key, then eventually
Holding content of text corresponding to available key " Del " is " deletion ", and content of text " deletion " is converted into voice by TTS
Data.
Step S103 plays the voice data.
Voice data after playing the content of text conversion of target key, such as the target key that user chooses is " Del "
When, then it can hear that the voice played out is " deletion ".
Further, before playing the voice data after the content of text conversion of target key, can first detect terminal is
Perhaps connection earphone directly plays the voice data by earphone if having detected earphone access or connection for no access,
If earphone access or connection is not detected, user is prompted to access earphone, and after detecting earphone access or connection
The broadcasting for carrying out voice data, to protect privacy of user.
Optionally, this method can also include:
When detecting the confirmation instruction of user's input, the corresponding word of the target key is exported in password viewing area
Symbol.
Confirmation instruction is to confirm the operational order for exporting selected target key as password, specifically be can be a little
It any of operations such as hits, double-click, sliding, shaking, being not especially limited here.When terminal detects that the confirmation of user's input refers to
When enabling, the corresponding character of target key in currently selected can be exported in password viewing area.For example, as shown in fig. 6, when using
Family chooses key 7 as after target key, has input and confirms instruction, then when terminal detects confirmation instruction, so that it may close
Code exports " 7 " this character in viewing area.
It obtains and plays the confirmation and instruct corresponding voice prompting message.
Further, confirmation can be preset and instruct corresponding voice prompting message, such as voice prompting message can be with
Setting are as follows: " confirmation output currently chooses number ", then terminal is available and play the voice and mention when getting confirmation instruction
Show message, has been exported using the corresponding number of target key for prompting user currently to choose as password.
The embodiment of the present invention is by the way that when detecting that safety keyboard is opened, monitoring user chooses for safety keyboard region
Operational order, determine described in choose operational order to choose the safety keyboard region in target key, then obtain described in
The content of text of target key calls the text-to-speech engine in terminal system to convert the content of text of the target key

Fig. 2 is the flow diagram of the reading screen method of another safety keyboard in the embodiment of the present invention, which comprises
Step S201 obtains the inductive operation of user's input, obtains the sense when detecting that safety keyboard is opened
The characteristic that should be operated.
Inductive operation is the operation that user does not carry out directly at the terminal, which can be connected by terminal or with terminal
Other sensing apparatus obtain, such as can by user action that sensor or other sensing apparatus are got, sound and/
Or the operation such as brain wave signal.Specifically, in the present embodiment, the inductive operation of above-mentioned user's input may include by having connected
The motor performance of wearable device input, the motor performance, defeated by infrared sensor that is inputted by the camera that has connected
The motor performance that enters is grasped by the sound control operation of microphone input, by the eeg signal that brain wave sensor inputs
At least one of the motor performance made and/or inputted by sonar unit.
After the inductive operation for getting user's input, need to carry out feature extraction to the inductive operation got, that is,
Obtain the characteristic of the inductive operation.In the present embodiment, different inductive operation, corresponding characteristic are different.
For example, the characteristic of acquisition can be but not limited to the inductive operation motion profile, fortune when inductive operation is motor performance
Dynamic duration, taps frequency, and/or movement range etc. at path length；For example, inductive operation be eeg signal operate when,
The characteristic of acquisition can be the E.E.G type, frequency, current potential of eeg signal etc. characteristic.That is, can be with
It is configured according to the demand of the concrete type of inductive operation and user, sets the induction behaviour for needing to extract in this step
The characteristic of work.
Step S202 is searched and the matched target signature data of the characteristic in preset property data base.
The characteristics of inductive operation, determines that the characteristic of same inductive operation is also different, therefore operates with choosing
Instructing corresponding target signature data is also not a fixed numerical value, but one or several range intervals or multiple spies
Levy numerical value.For example, including movement this parameter of duration in characteristic, then in general target signature data can be set as one
Time interval, such as 5s~10s.
After terminal gets the characteristic of inductive operation, need to search and this feature number in preset property data base
According to matched target signature data, that is to say, that can by motion profile, movement duration, path length, tap frequency, and/or
The characteristics such as movement range target signature parameter corresponding with this characteristic compares, and determines the feature ginseng got
Number whether be it is matched with target signature parameter, matching here can refer to that characteristic belongs to the range of target signature parameter
Section, can also refer to that characteristic is identical as one in target signature parameter or be consistent etc..
Step S203, acquisition is corresponding with the target signature data to choose operational order.
In the specific implementation, each group of target signature data, which have corresponded to one, specifically chooses operational order, for example, can be with
Corresponding to choose operational order be to switch to choosing by setting " movement duration 5s~10s " or/and " motion profile length 0.5m~2m "
In currently selected middle key right key, then when target signature data are " movement duration 5s~10s " or/and " motion profile
When length 0.5m~2m ", then it can determine that choosing operational order is to switch to the right key for choosing currently selected middle key.
Step S204 obtains the key being currently selected in the safety keyboard region.
It is currently chosen in safety keyboard region specifically, terminal after receiving and choosing operational order, can be obtained first
In key.
It should be noted that current selected key can be preset here, it is also possible to last terminal root
According to choosing the key chosen after operational order.For example, if terminal be get for the first time user input choose operation to refer to
Enable, have no the operation to selected key before, then it is currently selected in key can be preset, such as can be Fig. 5
In key 1；If terminal before according to choosing operational order to be operated, it is currently selected in key be
The selected key determined after last action.
Step S205 chooses operational order to determine key switching direction according to described.
Specifically, key switching direction is switching direction of the terminal in the selected key of switching, that is to say, that key
Switching direction determines that selected key is which of the up and down direction switching into safety keyboard region.For example,
As shown in figure 5, if key in currently selected is 5, key switching direction is to determine that terminal from 5 to 4 switches, or from 5 to 6
Switching, or from 5 to 2 switchings etc..
In the present embodiment, according to choosing operational order to be assured that key switching direction, such as operational order is chosen
Choose the right key of currently selected middle key that can then determine that key switching direction is to switch to the right to switch to.
Step S206 switches according to the key currently chosen in the safety keyboard region and the key
Direction determines the target key being selected after switching.
Specifically, can according to the key and key switching direction, terminal that are currently selected in safety keyboard region
The key being selected is switched to target key by current selected key.For example, as shown in fig. 6, in currently selected
Key be key 7, if key switching direction is determined as to the right, terminal can determine to the right switching after selected target
Key is 8.
Step S207 obtains the content of text of the target key, calls the text-to-speech engine in terminal system will
The content of text of the target key is converted to voice data.
Specific method can refer to step S102.
Step S208 plays the voice data.
Specific method can refer to step S103.
The embodiment of the present invention is by the way that when detecting that safety keyboard is opened, monitoring user chooses for safety keyboard region
Operational order, determine described in choose operational order to choose the safety keyboard region in target key, then obtain described in
The content of text of target key calls the text-to-speech engine in terminal system to convert the content of text of the target key
For voice data, the voice data is finally played, that is to say, that the payment in terminal device, which is applied, is detecting safety keyboard
When unlatching, what can be inputted with self monitor user chooses operational order for safety keyboard region, and operation will be chosen to refer to
It enables the target key chosen that content of text is switched to voice by TTS to play back, terminal device can be improved and applied in payment
In operation ease, in particular for there are the crowd of certain function obstacle, the raising of operation ease is particularly evident.
