In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be described in detail below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only It is a part of the embodiments of the present invention, but not all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art should fall within the protection scope of the present invention.

The information image display scheme provided by the present invention can use a physical button or a touch virtual button on a user device to implement a custom operation. For a user device with a touch screen, a virtual operation in an operating system interface or a specific application interface, or a specific touch gesture can be used to implement a custom operation. Of course, in order to display the information image, the user equipment may also have basic display functions. The specific user equipment may be a composite device such as a mobile phone, a tablet computer, a smart watch, or an electronic business card, an electronic label, etc. The single function device is not limited in the present invention. In the present invention, the information image may be a functional interface in an application, for example, a webpage, or a human-computer interaction interface, such as a payment interface. For example, for a payment application, the information image may be It is a payment interface such as a two-dimensional code, a one-dimensional barcode, or a variable barcode, and the application scenarios may be payment, access control, business card exchange, etc., which do not affect the implementation of the solution of the present invention.

FIG. 1 is a flowchart of an information image display method provided by the present invention. The execution subject of the method may be a user device such as a mobile phone. Specifically, the method may include the following steps: S101. Detect a user's input behavior. S102. After detecting the predefined user operation input, call the information image display function interface in the application where the information image is located to display the information image on the screen of the user device.

In the solution of the present invention, a predefined user operation can be used as a shortcut triggering method for a specific function interface in a specific application, such as a "payment code" function page in an electronic wallet application, a "my business card" function page in an electronic business card application, and the like . Specifically, the user input behavior can be detected when the mobile phone is powered on, and if a predefined user operation input can be detected. Enter, you can directly jump to the specific function page in the specific application above to display related information images, thereby simplifying the operation of displaying information images.

In the solution of the present invention, when the device detects a user-defined operation, it can directly call a specific function interface in a specific application instead of directly calling the application. In this way, the user can reduce the steps of opening the specific function interface and improve operation efficiency.

In the solution of the present invention, when a specific function interface displays an information image, it can obtain a static information image generated in advance, or it can generate an information image in real time. For example, in a quick display scene of a payment barcode interface in a payment application, the When the payment barcode interface is displayed, the information image of the payment barcode can be a static graphic or a graphic that can be generated in real time and can be dynamically changed. In actual use, the specific application can be launched in advance and run in the background of the system in order to achieve rapid call when information graphics are required to be displayed; if the reduction in the use of random access memory resources is considered, it can also be omitted. Pre-launch method. In this case, the device can start the specific application after detecting the predefined operation information.

In actual use, after detecting the predefined operation information, you can first find whether the corresponding application is already running in the system background. If it is, then switch directly to the application and jump to the specific function interface for displaying the information image; if If it is not found that the application is running in the background, the application is started (either in the background or in the foreground), and it jumps to a specific function interface for displaying an information image.

The following is an application scenario of using a mobile phone barcode (including one-dimensional barcode, two-dimensional barcode, etc.) for quick payment. Specifically, in the payment application The quick call out of the payment barcode interface is taken as an example to describe the solution of the present invention in detail.

Mobile phone users can pre-set an operation mode as a trigger password when payment bar code is displayed. This operation can use physical keys on the mobile phone (such as power button, volume up button, volume down button, etc., iOS mobile phone home button, keyboard type Any key of the mobile phone) or touch virtual keys (such as the Home key, Back key, Menu key, etc. of the Android mobile phone), you can also use the virtual keys in the touch screen mobile phone operating system interface or specific application interface, or specific touch Gesture implementation. Here are some examples of user-defined operations: Click a button: On some phones or operating systems, one or more buttons without preset functions will be provided. The user can define the functions of the button, such as screenshots. , Mute, launch specific apps, and more. This type of button can be directly used to implement the custom user operation of the solution of the present invention; long press a certain button: including the physical button that comes with the mobile phone, a touch virtual button, or a virtual button in the mobile phone interface, of which "long press" The standard is based on the configuration parameters of the operating system, which is not limited in the present invention.

Press two or more key combinations at the same time: it can be a combination of the same type of keys, such as pressing the power key and volume down key (both physical keys) at the same time; it can also be a combination of different types of keys, such as at the same time Press the power button (physical button) and the back button (touch virtual button).

Press two or more keys sequentially in a certain order: it can be a combination of keys of the same type, such as a password sequence, or a combination of keys of different types. In addition, you can limit the input Completed within the given time.

Specific touch gestures: By arranging and combining several dimensions such as click / long press / slide, single finger / multi-finger, specific screen position, etc., you can get multiple touch gestures, such as connecting to tap the screen twice, from the bottom of the screen Swipe to the top of the screen, long-press anywhere on the screen with three fingers, etc. These gestures can be used as custom user operations. In addition, you can also use specific sliding trajectories as custom user operations, such as drawing a "Z" shape on the screen, a "V" shape on the screen, and so on. Touch gestures can be implemented based on a touch screen, or can be implemented based on an independent touch device such as a touchpad.

There are many other implementations of the custom user operation, which are not exemplified in the present invention, as long as the custom user operation does not conflict with other operations in actual application. After the user enters a custom operation, the mobile phone side records and saves the key information. Of course, in some scenarios, some of the default operations of the device system can also be used as the user's predefined operations. The method for setting the user's predefined operations in the present invention, for example, is the system default or is set by the user, for example, it is set by the user in the system There are still user settings in a specific application in the system, which are not particularly limited.

In one embodiment, in order to ensure that the user can quickly trigger the bar code display by using a predefined operation at any time, a function of detecting a user's input behavior may be set to be continuously enabled. So that the user can enter the pre-defined operation information in any case to quickly display the payment barcode on the mobile phone screen.

In one embodiment, the user's input behavior can also be detected when the device is in a non-use state; the non-use state here can be Including: one or more of the locked state, hibernation state, standby state and other states.

It should be noted that among the above non-use states, the locked state represents a user's restriction on the device's operation rights, and the sleep and standby states are more descriptions of the device's software or hardware module working states. There is no clear division in definition. In some cases, the above several non-use states can exist on the same device at the same time, for example, some devices will automatically lock after a period of standby or hibernation, or automatically lock certain software and hardware modules after a period of lock Switch to standby or hibernation. In short, the common feature of the above states is that if the device is currently in these states, it will be more cumbersome for the user to use a conventional barcode display operation. By applying the above solution, the user can directly display the barcode without the operation steps such as waking up the device and unlocking the device in such cases, and can also avoid the power consumption caused by the input detection function being turned on for a long time.

In an embodiment of the present invention, according to the operation sequence of “wake up, then unlock” of a general smart device, the timing of detecting the user's input behavior can also be set to “after the user device is woken up from the sleep state, And not unlocked ". In other words, the input behavior detection function may not be turned on most of the time when the mobile phone is not used (for example, when it is placed in a pocket or a purse). When the phone is awakened in other ways (such as the power key, volume key, etc.), the input detection function is activated, and the following situations can occur:

1) The user inputs a predefined user operation and invokes a payment barcode interface in a payment application for quick payment.

2) The user unlocks the phone normally (by password, gesture, etc.). After the unlock is successful, the phone enters the use state, and the input behavior detection function is turned off.

3) The user did not enter any information, which may be caused by misoperation. After a period of time, the mobile phone resumes hibernation and the input behavior detection function is turned off.

It can be seen that the application of the above solution can further shorten the opening time of the input behavior detection function under the premise of adapting to the basic operating habits of the user, thereby reducing the power consumption of the device.

In an embodiment of the present invention, if no other user operation on the device is detected within a period of time after the information image is displayed, the information image may be stopped from being displayed. In order to prevent information images from being photographed, stolen, etc., the security of information use is improved. The threshold for controlling the stop of displaying the information image can be set according to actual needs, such as 30 seconds, 60 seconds, and so on. The specific implementation of stopping the display of the information image may be exiting a specific information image display function interface, exiting a specific application, returning to the system standby interface, or restoring the device to a locked state, a hibernation state, etc. The present invention does not address this. Limitation.

FIG. 2 is a schematic diagram of a specific implementation scenario in which the solution of the present invention is applied to a merchant's payment. When the mobile phone is in a dormant and locked non-use state, the user draws a “Z” -shaped pattern on the mobile phone screen with a gesture. The user-defined operation gestures are used for matching authentication. After the authentication is passed, the barcode (including one-dimensional barcode and two-dimensional barcode) image in the payment application is triggered to be displayed on the mobile phone screen. If the user does not perform other operations on the mobile phone for more than 60 seconds, the barcode image displayed on the mobile phone screen disappears, and the mobile phone can be restored to a non-use state.

In order to improve the security of the information image, other security verification mechanisms can be further added. For example, after detecting a predefined user operation input and before displaying an information image, the user may be required to enter one or more types of authentication information. The authentication information may be in the form of a text password, fingerprint, gesture, etc. If the authentication information entered by the user is correct, The information image is displayed, and if the user enters the authentication information incorrectly, the information image is not displayed.

FIG. 3 is a schematic diagram of a specific implementation scenario where the solution of the present invention is applied to a merchant's payment. When the mobile phone is in a black screen, lock screen, or standby state, the user enters a “bottom-up” sliding gesture on the mobile phone screen, and the mobile phone side responds to the gesture Match and authenticate with the pre-stored custom operation gestures. After the authentication is passed, the payment application is invoked. The current payment method is displayed on the screen (the user can modify it according to requirements), and the user is prompted to enter the payment password. Enter the fingerprint information. The mobile phone uses local or sent to the network to authenticate the payment password and fingerprint information. After the authentication is passed, the payment barcode is displayed on the mobile phone screen. It can be understood that before displaying the payment barcode, the user may be required to enter only one type of authentication information, or use other authentication information, which is not limited in the present invention.

In an embodiment of the present invention, the device may also be unlocked by using a predefined user operation. In order to distinguish between the function of "unlocking by using a predefined user operation" and the function of "displaying an information image quickly by using a predefined user operation", The invention provides the following solution: a user can pre-register a predefined user operation (hereinafter referred to as a "display operation") for displaying an information image and a method for unlocking a user device, respectively. Predefined user actions (hereinafter referred to as "unlock actions"). And the association between the "display operation" and "calling the information image display interface processing in a specific application" and the association between the "unlock operation" and "unlocking user device processing" are respectively established. Furthermore, in the locked state of the user device, after the input behavior detection function detects the user's currently input operation, different processing is performed according to the matching between the currently detected operation and the pre-stored predefined user operation. See FIG. 4: S201, When the user device is locked, the user's input behavior is detected; if no user operation is detected, no processing is performed, and if a user operation is detected: if the currently detected user operation matches the "display operation" , Execute S202 to call the information image display function interface in the information image application, and display the information image on the screen of the user device.

If the currently detected user operation matches the "unlock operation", step S203 is performed to perform unlock processing on the user equipment.

The mobile payment barcode application scenario is still used as an example. Assume that the mobile phone is unlocked using a graphic method. According to the usage habits, the user can enter the gesture drawing graphic "N" as the "unlock operation" and the gesture drawing graphic "Z" as the "display operation" . In actual use, when the user takes out the mobile phone and performs a wake-up operation, the mobile phone screen displays an unlock prompt. At this time, if the user needs to display the payment barcode quickly, draw a graphic "Z" on the screen, and call the payment barcode in the payment application after the match is successful Interface and display to the user on the phone screen; if the user needs to use other functions of the phone, on the screen Draw a graphic "N", and the phone will be unlocked by default after successful matching.

In one embodiment, assuming that the mobile phone is unlocked with a digital password, according to the usage habits, the user may enter the password "1111" as the "unlock operation" and the password "2222" as the "display operation". In actual use, the user takes out the mobile phone, and after the wake-up operation is performed, the mobile phone screen displays an unlock prompt. At this time, if the user needs to display the payment barcode quickly, enter the password "2222" and call the payment barcode display interface in the payment application after the match is successful Display; if the user needs to use other functions of the phone, enter the password "1111", and the phone will be unlocked by default after successful matching.

It can be seen that, by using the foregoing manner, the two operations of “quick display” and “unlock” can be effectively distinguished without affecting the normal usage habits of the user.
