Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a block diagram of a structure of a focus movement system according to an embodiment of the present invention, where fig. 1 shows a selectable application scenario of the focus movement system according to the embodiment of the present invention, and specifically includes: the remote control device comprises a remote controller 1 and an intelligent television 2, wherein the current user interface of the intelligent television 2 comprises a plurality of program sections, and each program section can be called as a focus object.
The present invention provides a focus moving system, which determines a focus moving command sent by a user through a remote controller according to the touch operation of the user, determines a next target focus object to obtain a focus, that is, a program section other than the program section one (focus object 21) in fig. 1, according to the focus moving command and a preset focus moving rule, and further moves the focus to the target focus object.
Based on this idea, referring to fig. 2, a flowchart of a focus moving method provided in an embodiment of the present invention is shown in conjunction with fig. 1 and fig. 2, where the flowchart may include:
in step S100, a focus movement command is acquired.
In practical applications, for a terminal device without a mouse or a touch screen, a focus moving command is often to control a focus to gradually move in four directions, namely up, down, left, and right, and move the focus to a destination corresponding to specific command content to select a corresponding focus object.
Therefore, the manner in which the user sends the focus movement command at least includes: and sending a focus moving command through a remote controller or triggering the focus moving command through a physical key arranged on the terminal equipment body. Of course, other ways of sending the focus movement command are possible, and are not limited to the above-mentioned two command generation ways.
Correspondingly, there are also multiple ways to obtain the focus movement command, and the method can obtain a wireless signal sent by a remote controller, or acquire a key value of a physical key pressed by a user on a terminal device, and further determine the content of the focus movement command according to the content of the key value, or obtain the focus movement command sent by the user through a smart phone, and the like.
Step S110, determining at least one candidate focus object adjacent to the current focus object according to the focus movement command.
After the focus moving command is obtained, the content of the focus moving command needs to be analyzed, and then at least one candidate focus object adjacent to the current focus object can be determined according to the content of the focus moving command.
Optionally, to simplify the analysis process of the focus movement command, a specific focus movement command may be assigned, for example, the upward movement command is assigned to-1, the downward movement command is assigned to 1, the leftward movement command is assigned to-2, and the rightward movement command is assigned to 2. Of course, the key values corresponding to the control keys may be directly used for identification, or the control keys may be numbered, which control key is triggered is determined according to the number, and the command content corresponding to the control key is further analyzed.
After analyzing the obtained focus movement command, the movement direction of the focus may be determined according to the content of the focus movement command, for example, if a value obtained by obtaining and analyzing a certain focus movement command is 2, the movement direction of the focus may be determined to be the right.
According to the moving direction of the focus, at least one focus object adjacent to the current focus object in the focus moving direction needs to be further determined as a candidate focus object. It should be noted that the focus object mentioned in the present application may be a component, a view, or another unit in the user interface that can obtain the focus.
As is well known in the art, any type of focus object has a boundary with a certain width during the setting process, and thus, at least one candidate focus object adjacent to the current focus object in the focus moving direction may be determined using the boundary of the focus object. Optionally, since any one of the focus objects has a plurality of focus boundaries, a boundary that coincides with the focus movement direction among the boundaries of the current focus object in each direction is determined as a target boundary, and then a focus object whose boundary intersects with the target boundary is determined as a candidate focus object. It is conceivable that, since the boundary of the focus object has a certain length, there is at least one focus object intersecting with the target boundary of the current focus object, i.e., at least one candidate focus object.
Step S120, determining a target focus object from the candidate focus objects according to a preset focus movement rule.
The preset focus moving rule defines the priority of the focus in the moving sequence, and when a plurality of candidate focus objects exist, the target focus object needs to be further determined according to the preset focus moving rule.
Optionally, if the focus movement rule is first up and then down, and first left and then right, that is, for a certain focus movement command, the position information of each candidate focus is obtained, and the candidate focus object at the leftmost side and at the topmost side should be determined as the target focus object.
It should be noted that the preset focus movement rule may be designed according to practical situations, and is not limited to the content provided above, and any focus movement rule that can be used to determine the target focus object among multiple candidate focus objects is optional, and also falls within the scope of the present invention.
Step S130, moving the focus to the target focus object.
After the target focus object is determined, the focus can be moved to the target focus object, and the movement of the focus is completed.
According to the focus moving method provided by the invention, the movement of the focus is realized according to the focus moving command and the preset focus moving rule, at least one candidate focus object is obtained by calculation after the focus moving command is obtained every time, and the target focus object of the focus moving is further determined according to the preset focus moving rule, and the determination of the focus moving position does not depend on the arrangement of the focus objects in the user interface, so that a developer can change and upgrade the user interface according to the need without recalculating the target focus objects corresponding to the current focus object in the upper, lower, left and right directions, the limitation factor of the user interface on upgrading and changing is reduced, and the working efficiency is improved.
Alternatively, in practical applications, the movement of focus may occur between focus objects at different levels, such as between components and views, in some cases. Therefore, the present application also provides a preferred embodiment, which realizes the focus movement when the objects of the focus movement are in different levels.
Specifically, if the focus object intersecting with the target boundary is a previous view of the current focus object, a boundary object needs to be generated, and the command content of the current focus movement command and the parameter information of the current focus object are recorded in the boundary object.
Optionally, the definition of the boundary object may be:
BorderObj: { type: -1| -2|1|2, position: { left, top, width, height }, isInside }, and as can be seen from the definition content, the boundary object contains the command content (type: -1| -2|1|2) and the basic parameters (position: { left, top, width, height }) of the current focus object, and IsInside is used for identifying whether the boundary object is generated inside the view or not or is transmitted outside.
Based on the information contained in the boundary object, at least one candidate focus object may be determined or a candidate region may be partitioned, and the focus objects in the region may be used as candidate focus objects. Further, the target focus object is determined according to a preset focus movement rule, for example, the focus object at the leftmost position and the uppermost position in the candidate region is determined as the target focus object.
After the target focus object is determined, the focus may be jumped to the target focus object.
Optionally, in order to further increase the determination speed of the target focus object and shorten the execution time of the focus moving command, the present application provides a preferred embodiment, and referring to fig. 3, a flowchart of another focus moving method provided in the embodiment of the present application includes:
in step S200, a focus movement command is acquired.
Optionally, an optional implementation of step S200 may be as shown in step S100 in fig. 2, and is not described here again.
In step S210, the focus movement command is analyzed to obtain the focus movement direction.
After the focus moving command is obtained, the content of the focus moving command needs to be analyzed first, and then the focus moving direction can be obtained according to the content of the focus moving command.
The focus movement command at least includes four types of up movement, down movement, left movement and right movement, and the focus movement command is analyzed according to a preset analysis mode of the focus movement command, such as assignment of different focus movement commands or identification of key values of physical keys sending the focus movement command, and the focus movement direction is obtained according to the content of the focus movement command.
In step S220, it is determined whether an adjacent focus object of the current focus object in the focus moving direction is stored, if yes, step S250 is executed, and if not, step S230 is executed.
Each time the focus moves, two focus objects are involved, one is the current focus object, the other is the target focus object, for the user interface which has started to be used, the adjacent focus objects in the upper, lower, left and right directions in any one focus object in the user interface are often fixed, that is, the corresponding relationship is fixed, therefore, after the same focus moving command is sent for the same current focus object, the focus is inevitably moved to the same adjacent focus object, that is, the target focus object. It should be noted that the storage operation occurs after all the execution steps shown in the embodiment shown in fig. 1, and in the using process of the user, the focus movement relationship between the focus objects is continuously recorded, and the storage record is continuously perfected until all the adjacent focus objects of all the focus objects in any focus movement direction are completely stored.
Optionally, the specific storage operation includes: a first adjacent focus object stored above and adjacent to the current focus object, a second adjacent focus object stored below and adjacent to the current focus object, a third adjacent focus object stored to the left of and adjacent to the current focus object, and a fourth adjacent focus object stored to the right of and adjacent to the current focus object.
Optionally, the structure for implementing the storage content may be as follows:
MapItem:{-1：nextPos,2:nextPos,1:nextPos,2:nextPos}；
ActionMap:{pos1:MapItem1,pos2:MapItem2,...}。
it should be noted that, in the initial stage of application after the user interface is upgraded or modified, especially in the first application, the storage function provided by this embodiment is certainly not applied, and as the storage information becomes richer and richer, this function can be generally applied, and the execution efficiency of the user instruction is effectively improved.
In step S230, at least one candidate focus object adjacent to the current focus object is determined according to the focus movement command.
Optionally, an optional implementation of step S230 may be as shown in step S110 in fig. 2, and is not described here again.
In step S240, a target focus object is determined from the candidate focus objects according to a preset focus movement rule.
Optionally, an optional implementation of step S240 may be as shown in step S120 in fig. 2, and is not described here again.
It should be noted that, referring to fig. 3, after the step S240 is completed, the step S260 should be executed instead.
In step S250, it is determined that the adjacent focus object of the current focus object in the focus moving direction is the target focus object.
If the adjacent focus object of the current focus object in the focus moving direction is stored, the target focus object of which the focus moves in the focus moving direction can be directly determined according to the history information.
In step S260, the focus is moved to the target focus object.
After the target focus object is determined, the focus can be moved to the target focus object, and the movement of the focus is completed.
Optionally, referring to fig. 4, a flowchart of another focus moving method provided in an embodiment of the present invention includes:
in step S300, a focus movement command is acquired.
Optionally, an optional implementation of step S300 may be as shown in step S100 in fig. 2, and is not described here again.
Step S310, determining whether the moving relationship includes the current focus object, if yes, performing step S340, and if no, performing step S320.
The movement relationship of the focus between the focus objects includes a focus movement direction corresponding to the focus object and a target focus object, and the movement relationship described in the embodiment of the present application mainly records a path along which the focus moves to the target focus object after moving in a certain direction on the current focus object.
Optionally, the movement relationships of the focus among the preset number of focus objects may be stored by a stack, for example, the latest three movement relationships stored in the stack may be defined, and the movement relationships stored in the stack are continuously refreshed according to a rule of reading data from the stack. The storage moving relationship based on the stack structure can adopt the following structure:
PathItem: { type: -1| -2|1|2, toPos, fromPos }, where fromPos refers to the current focus object and toPos refers to the next focus object.
It should be noted that the storage of the movement relationship also occurs after each time the focus movement command is executed, and is applied to the next execution of the focus movement command, so that, for the focus movement command acquired for the first time, it is certain that the movement relationship cannot be applied, the target focus object is quickly determined, and the focus movement command is executed. If the storage of the movement relationship is in the form of a stack, only a preset number of recently executed focus movement commands can be stored in the stack based on the storage characteristics of the stack, and focus movement commands before the preset number are refreshed and are not stored and memorized.
In step S320, at least one candidate focus object adjacent to the current focus object is determined according to the focus movement command.
Optionally, an optional implementation of step S320 may be as shown in step S110 in fig. 2, and is not described here again.
In step S330, a target focus object is determined from the candidate focus objects according to a preset focus movement rule.
Optionally, an optional implementation of step S330 may be as shown in step S120 in fig. 2, and is not described here again.
It should be noted that, referring to fig. 4, after the step S330 is completed, the step S370 should be executed instead.
In step S340, a target moving direction opposite to the current moving direction is determined.
After the focus moving command is obtained, the current moving direction is determined according to the content of the focus moving command, and the target moving direction opposite to the current moving direction is further searched and obtained from the moving relation.
Step S350, determining whether a target movement relationship in which the current focus object is the target focus object and the movement direction is the target movement direction exists in the stored movement relationships, if yes, performing step S360, and if not, performing step S320.
The step is mainly used for determining whether a target movement relationship exists, the focus movement direction recorded in the target movement relationship is the target movement direction determined in the previous step, and the recorded target focus object is the current focus object. If the stored movement relationship includes the target movement relationship, step S360 is executed, and if the target movement relationship does not exist, step S320 is executed again.
The essence of this step is to determine whether there is a historical focus movement command as opposed to the current focus movement command.
Step S360, determining that the initial focus object in the target movement relationship is the target focus object corresponding to the current focus movement command.
If the target movement relationship exists, the starting focus object recorded in the target movement relationship is the target focus object corresponding to the current focus movement command.
In step S370, the focus is moved to the target focus object.
After the target focus object is determined, the focus can be moved to the target focus object, and the movement of the focus is completed.
The embodiment shown in fig. 4 mainly solves the problem that when a user sends a certain focus moving command, sends an opposite focus moving command and wants to return to a previous focus object, a target focus object can be quickly determined, the execution of the focus moving command is completed, the target focus object does not need to be selected again, calculation errors are avoided, and meanwhile, the command execution efficiency is improved.
It is conceivable that the embodiments shown in fig. 3 and fig. 4 respectively provide a preferred embodiment, and on the premise that the judgment condition is satisfied, some steps in the embodiment shown in fig. 2 are not necessary to be performed to speed up the execution process of the focus movement command, and similarly, the modified contents shown in fig. 3 and fig. 4 may be combined together, and it is also possible to respectively judge whether the corresponding preferred step can be adopted for one focus movement command.
