Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.

Example one

Fig. 1A is a flowchart of a method for displaying virtual keys according to an embodiment of the present invention, where this embodiment is applicable to dynamically adjusting display positions of function keys in an interface of an embedded system, and the method may be executed by a display apparatus for virtual keys in an embodiment of the present invention, where the display apparatus may be implemented by software and/or hardware, and may be integrated in an embedded system, and typically may be integrated in a Micro Controller Unit (MCU) of the embedded system, where the method specifically includes the following steps:

s110, when a function key triggering instruction is detected in the target interface, determining a triggered target function key, and updating the triggering frequency of the target function key.

The embedded system usually includes a plurality of interfaces, and some interfaces may not include any function button, for example, interface a is only used to display monitoring information of certain status parameters, and does not include any virtual button that can be triggered, so if the currently presented interface does not include any function button or only includes one function button, there is no need to monitor the triggering frequency of the function button of the interface.

The function key is a virtual key including at least one sub-function interface, that is, after the function key is triggered, the function interface of the next level matched with the function key is displayed, for example, as shown in fig. 1B, the main interface includes six keys of "function 1", "function 2", "function 3", "function 4", "function 5" and "function 6", after the "function 5" key is triggered, the interface B is displayed, the sub-function keys of "function 5" key, function 5.1 "," function 5.2 "and" function 5.3 "are displayed in the interface B, obviously, the interface B is the sub-function interface of" function 5 "key, and is the sub-function interface of the first level, if the" function 5.1 "key is triggered in the interface B, the interface C is displayed, the sub-function keys of" function 5.1.1.2 "and" function 5.1.3 "are displayed in the interface C, obviously, the interface C is also a sub-function interface of the function 5 key and is a sub-function interface of a second level; in particular, the interface C is also a sub-function interface of the "function 5.1" key, and is a sub-function interface of the first level; as shown in fig. 1C, after the "function 3" key is triggered, an interface D is displayed, and although the interface D does not include any virtual key, various monitored system state information, that is, "temperature information," "load information," and "storage information," is displayed, so that the interface D is a sub-function interface of the "function 3" key and is a sub-function interface of a first level, and the "function 3" key only includes the sub-function interface of the first level.

Particularly, for the universal keys such as "return", "jump home" and "refresh" in the interface, because the universal keys are often displayed in each interface and the display positions are relatively fixed, if the display positions of the universal keys are adjusted, the display positions of the universal keys in different interfaces are different, which is not in line with the use habit of the user, the universal keys can be used as the functional keys in the embodiment of the present invention, that is, the trigger frequency of the universal keys is not monitored; the type of the universal key can be preset according to the requirement.

After determining the triggered target function key, the number of triggers of the target function key is increased by 1, and the trigger frequency is determined according to the number of triggers within a past period of time (e.g., one day, one week, or one month).

S120, determining the arrangement sequence of the function keys in the target interface according to the trigger frequency of the function keys in the target interface.

The higher the trigger frequency, the more frequently the user uses the function key, so when sorting the function keys according to the trigger frequency, the higher the trigger frequency, the earlier the sorting.

Optionally, in this embodiment of the present invention, the determining, according to the trigger frequency of each function key in the target interface, an arrangement order of each function key in the target interface includes: and determining the arrangement sequence of each function key in the target interface according to the trigger frequency of each function key in the target interface and the weight coefficient of each function key. The weight coefficient is a weight value preset for each function key in the interface, the larger the value is, the higher the default display priority of the function key in the embedded system is, the higher the importance is, and at the same time, the weight coefficient is also the basis for setting the initial display position for each function key, for example, in fig. 1B, the weight coefficients of "function 1", "function 2", "function 3", "function 4", "function 5" and "function 6" are sequentially reduced, and the default display positions in the main interface are also sequentially arranged in the same order, so that the trigger frequency of each function key and the corresponding weight coefficient are summed or multiplied, and then the function keys are arranged according to the summation or multiplication result, and the use frequency of each function key by the user and the importance degree of each function key are comprehensively considered, and acquiring a more reasonable function key arrangement sequence.

Optionally, in this embodiment of the present invention, the determining, according to the trigger frequency of each function key in the target interface, an arrangement order of each function key in the target interface includes: determining the arrangement sequence of each function key in the target interface through a sequencing model according to the triggering frequency, the weight coefficient and the triggering times of each function key in the target interface; wherein the ranking model is constructed based on a neural network. If the use time of the user is short or the triggering times of all the function keys are less, the use habits of the user cannot be truly reflected by fewer sampling samples at the time, so that the triggering frequency, the weight coefficient and the triggering times of all the function keys in the currently displayed target interface are used as input data through the pre-trained sorting model, all the function keys are sorted based on the input data, and the output data is the sorting result of all the function keys in the current target display interface.

Taking the example that the sorting model uses the linear excitation function, the more the triggering times of the function keys are, the higher the correction value of the triggering frequency is, for example, the using frequency of the function key a is 5 times/day, and when the actual triggered times are 100 times, the obtained excitation value is obviously larger than that when the actual triggered times are 10 times, and further, the larger the correction value of the obtained triggering frequency is, the larger the probability value is when sorting is performed, and the more the sorting position is likely to be forward, so that the sorting model constructed based on the neural network performs sorting operation on each function key in the target display interface, and the accuracy of the sorting result of each function key is further improved; in particular, in order to reduce the resource occupation of the MCU in the embedded system, a single-layer or a small number of layers of neural networks may be used to construct the order model, so that the order model with a simplified structure occupies a small amount of MCU resources.

Optionally, in this embodiment of the present invention, after determining the triggered target function key, the method further includes: and if the fact that the sub-function key of the target function key is triggered is detected in the sub-function interface of the preset level under the target function key, updating the trigger frequency of the target function key. There may be one or more levels of sub-function interfaces under a function key, for example, the "function 5" key in fig. 1B includes two levels of sub-function interfaces, and the "function 3" key in fig. 1C includes one level of sub-function interfaces; the sub-function interfaces of the preset hierarchy are sub-function interfaces of one or more hierarchies specified under the function keys, for example, only the sub-function interface of the first hierarchy under each function key is taken as the sub-function interface of the preset hierarchy, taking fig. 1B as an example, according to the setting that the preset hierarchy is the first hierarchy, if the function 5.1 key is detected to be triggered in the interface B, the function 5.1 key is considered to have an association relationship with the function 5 key, and is also considered to be triggered by the function 5 key, so that when the function 5.1 key is triggered, the triggering frequency of the function 5 key is also updated; similarly, according to the setting that the preset hierarchy is the first hierarchy, if the function 5.1.1 key is triggered in the interface C, the function 5.1.1 key and the function 5 key are not considered to have an association relationship and are not considered to be triggered by the function 5 key, so that when the function 5.1.1 key is triggered, the trigger frequency of the function 5 key is not updated; by setting the sub-function interface with the preset level, the use frequency of the sub-functions of the user under each function key can be obtained, and the actual use condition of the user on each system function can be reflected more accurately.

In particular, the sub-function interfaces of the preset hierarchy are related to the interface attribute of the target interface; wherein the interface attribute comprises an interface type and/or an interface hierarchy. Different interfaces may correspond to different preset levels, for example, the interface type may include a main interface and a non-main interface, and for the main interface, since the main interface has the highest importance and the level of the included sub-function interface is the most, the sub-function interfaces of the preset level corresponding to each function key in the main interface may be set to a larger value, for example, the sub-function interfaces of the first level, the second level, and the third level corresponding to each function key in the main interface are used as the sub-function interfaces of the preset level, and for the non-main interface, the sub-function interfaces of the preset level corresponding to each function key in the non-main interface may be set to a smaller value, for example, only the sub-function interfaces of the first level corresponding to each function key in the non-main interface are used as the sub-function interfaces of the preset level; the interface level is a position level of the interface in the system, for example, in fig. 1B, the main interface is located at the first level of the system, the interface B is located at the second level of the system, the interface C is located at the third level of the system, the position levels of the interfaces in the system are different, the sub-function interfaces of the preset level corresponding to each function key in the interface may also be different, and the higher the interface level is, the more the number of the sub-function interfaces of the preset level is. By setting the sub-function interfaces of the preset levels, the detection of different numbers of sub-function interfaces is realized for different interfaces, the multi-level detection of the important interfaces is ensured, the detection of fewer levels is also carried out for non-important interfaces, and the detection resources of the embedded system are reasonably utilized.

S130, adjusting the display position of each function key in the target interface according to the arrangement sequence of each function key.

According to the arrangement sequence of the function keys, the function keys are sequentially placed at the designated display positions in the display interface, and by taking the target interface as the main interface and taking the target function key as the "function 5" key as an example, the display positions before and after the adjustment of the function keys are respectively displayed in fig. 1D.

Optionally, in an embodiment of the present invention, before adjusting a display position of each function key in the target interface according to an arrangement sequence of each function key, the method includes: judging whether the trigger data of the target function key accords with an adjustment rule or not; wherein the trigger data comprises a trigger frequency and/or a trigger number; if the trigger data of the target function key is determined not to accord with the adjustment rule, keeping the display position of each function key in the target interface unchanged; adjusting the display position of each function key in the target interface according to the arrangement sequence of each function key, including: and if the trigger data of the target function keys are determined to accord with the adjustment rule, adjusting the display positions of the function keys in the target interface according to the arrangement sequence of the function keys.

If the triggering frequency of the target function key is greater than or equal to the preset frequency threshold and/or the triggering times of the target function key are greater than or equal to the preset time threshold, the triggering data of the target function key is shown to accord with the adjustment rule, and at the moment, the display position of each function key in the target interface is adjusted; if the triggering frequency of the target function key is smaller than the preset frequency threshold and/or the triggering times of the target function key are smaller than the preset time threshold, the triggering data of the target function key is not in accordance with the adjustment rule, and at the moment, the display position of each function key in the target interface is kept unchanged; by setting the adjustment rule, the sequencing result does not influence the actual display position of each function key in the target interface when the use time of the user is short or the triggering times of each function key are small, and the misjudgment of the use habits of the user based on the triggering result obtained by a small number of sampling samples is avoided.

According to the technical scheme provided by the embodiment of the invention, the triggering frequency of the target function key is updated according to the triggering instruction of the function key in the target interface, the arrangement sequence of the function keys in the target interface is determined according to the triggering frequency of the function keys in the target interface, and the display position of the function keys in the target interface is adjusted according to the arrangement sequence of the function keys, so that the display position of the function keys in the interface is adjusted according to the operation habit of a user, the convenience of user operation is improved, and the user experience is improved.

Example two

Fig. 2 is a flowchart of a method for displaying virtual keys according to a second embodiment of the present invention, which is embodied on the basis of the foregoing technical solution, and in this embodiment, when a display instruction of the target interface is obtained again, an arrangement order of each function key in the target interface is determined according to a trigger frequency of each function key in the target interface, where the method specifically includes:

s210, when a function key triggering instruction is detected in the target interface, determining a triggered target function key, and updating the triggering frequency of the target function key.

S220, if the fact that the sub-function key of the target function key is triggered is detected in the sub-function interface of the preset level under the target function key, updating the trigger frequency of the target function key.

And S230, when the display instruction of the target interface is obtained again, determining the arrangement sequence of the function keys in the target interface according to the trigger frequency of the function keys in the target interface.

Aiming at the sorting operation executed by the function keys, the purpose is to adjust the display position of each function key in the target interface so that the adjusted interface conforms to the use habit of a user when the interface is displayed to the user, therefore, the sorting operation executed by the function keys can be carried out when a display instruction of the interface is acquired next time; this is because the user may continue to use other sub-functions under the target function key after triggering the target function key, and further frequently update the trigger frequency of the target function key, and in the update process of the trigger frequency, the target interface is not substantially displayed to the user, and if the trigger frequency of the target function key is updated each time, the sorting of the function keys is performed, which may cause a waste of computing resources.

S240, adjusting the display position of each function key in the target display interface according to the arrangement sequence of each function key.

According to the technical scheme provided by the embodiment of the invention, the triggering frequency of the target function key is updated according to the function key triggering instruction in the target interface, when the display instruction of the target interface is obtained again, the arrangement sequence of the function keys in the target interface is determined according to the triggering frequency of the function keys in the target interface, and the display position of the function keys in the target interface is adjusted according to the arrangement sequence of the function keys, so that the display position of the function keys in the interface is adjusted according to the operation habit of a user, the convenience of the user operation is improved, and meanwhile, the computing resources of an embedded system are saved.
