This application claims priority and benefits to Chinese Application No. 202110703359.5, filed on Jun. 24, 2021, the entire content of which is incorporated herein by reference.
The disclosure relates to a field of computer technologies, and particularly to a method and an apparatus for controlling an interface focus on an interface, an electronic device and a storage medium.
At present, a focus state scene is emerging as the in-vehicle scene has been rapidly developed. The in-vehicle scene refers to a scene inside the vehicle that is monitored or estimated by an in-vehicle system. The in-vehicle system includes sensors that measure, capture, and/or receive data relating to the attributes of the vehicle, and a set of onboard information and entertainment devices for realizing the information communication between users and the vehicle and between the vehicle and the outside world. The focus state scene refers to a scene describing a focus state of an interface focus on an onboard screen of the in-vehicle system. The interface focus refers to an element on the onboard screen, and the focus state refers to highlighting the element, such that the element can be interacted with.
According to one aspect of the disclosure, a method for controlling an interface focus on an interface is provided. The method includes acquiring a key operation instruction from a terminal device, in which the key operation instruction includes a key identifier and a corresponding key manner; processing a current display interface based on the key identifier and the key manner; and projecting the processed display interface on a display screen of an in-vehicle system.
According to another aspect of the disclosure, an electronic device is provided. The electronic device includes: at least one processor; and a memory communicatively connected to the at least one processor. The memory stores instructions executable by the at least one processor. When the instructions are performed by the at least one processor, the at least one processor is caused to perform a method for controlling an interface focus on an interface in the disclosure.
According to another aspect of the disclosure, a non-transitory computer readable storage medium stored with computer instructions is provided. The computer instructions are configured to cause the computer to perform the method for controlling an interface focus on an interface according to the embodiment of the disclosure.
It is understandable that, the content described in the part is not intended to identify key or important features of disclosure, nor intended to limit the scope of the disclosure. Other features of the disclosure will be easy to understand through the following specification.
The drawings are intended to understand the solution, and do not constitute a limitation to the disclosure.
The embodiments of the disclosure are described as below with reference to the accompanying drawings, which include various details to facilitate understanding, and should be considered as examples. Therefore, those skilled in the art should realize that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the disclosure. Similarly, for clarity and conciseness, descriptions of well-known functions and structures are omitted in the following descriptions.
In the related art, most of in-vehicle systems control the focus state through hard keys such as a knob or a touchpad. When the physical hardware (e.g., the knob or the touchpad) is broken or an onboard screen of the in-vehicle system that is controlled by touches does not work properly, the user cannot use the focus state. Therefore, how to efficiently and rapidly use a focus state function is a problem to be used. The in-vehicle scene refers to a scene inside the vehicle that is monitored or estimated by an in-vehicle system. The in-vehicle system includes sensors that measure, capture, and/or receive data relating to the attributes of the vehicle, and a set of onboard information and entertainment devices for realizing the information communication between users and the vehicle and between the vehicle and the outside world. The focus state scene refers to a scene describing a focus state of an interface focus on an onboard screen of the in-vehicle system. The interface focus refers to an element on the onboard screen, and the focus state refers to highlighting the element, such that the element can be interacted with.
A method and an apparatus for controlling an interface focus on an interface, an electronic device and a storage medium according to the embodiments of the disclosure will be described below with reference to attached drawings.
As illustrated in
At block 101, a key operation instruction is acquired from a terminal device. The key operation instruction includes a key identifier and a corresponding key manner.
In some embodiments, the “terminal device” mentioned in the disclosure may be, but not limited to, a smart phone, a tablet computer, a smart portable device, etc.
It is understandable that, the key identifier included in the key operation instruction refers to an identifier of an operated key. For example, the operated key may be a volume increasing key, a volume reducing key, or a power supply key. The corresponding key manner included in the key operation instruction refers to a manner of operating the operated key. For example, the key manner may include, but not limited to, a single click, a double click, a long press, etc.
At block 102, a current display interface is processed based on the key identifier and the key manner.
In some embodiments, the obtained key identifier and the key manner can be used to simulate an event message corresponding to a hardware key related to an interface focus of the in-vehicle system. Correspondingly, the focus state on the current display interface may be controlled based on the event message to acquire a processed display interface.
At block 103, the processed display interface is projected on a display screen of the in-vehicle system.
With the method for controlling an interface focus on the display interface according to the disclosure, the processed display interface is obtained by processing the current display interface based on the key identifier and the corresponding key manner from a terminal device, and the processed display interface is projected on the display screen of the in-vehicle system. Therefore, the processing of the current display interface is realized through the key operation instruction from the terminal device, the processed display interface is synchronized to the display screen of the in-vehicle system, and the focus state function is achieved by the hardware keys of the terminal device, which improves the user experience and facilitates use.
As illustrated in
At block 201, a key operation instruction is acquired from a terminal device. The key operation instruction includes a key identifier and a corresponding key manner. The descriptions of block 101 are also applicable to the block 201.
At block 202, a focus control instruction on the focus object is determined based on the key identifier and the key manner.
At block 203, the focus object is controlled based on the focus control instruction.
In some embodiments, it is possible that there are a plurality of focus objects on the current display interface. In this case, in order to accurately control the plurality of focus objects, when the focus control instruction is a displaying instruction of displaying focus objects in the focus state manner, a displaying sequence of displaying the focus objects in the focus state manner is determined based on the displaying instruction, and the plurality of focus objects are displayed sequentially in the focus state manner based on the displaying sequence. Thus, the key operation instruction from the terminal device may be used to control the displaying sequence of displaying the plurality of focus object in the focus state manner, to accurately control the plurality of focus objects on the current display interface.
In some examples, the focus object is a focus region, and in this case, displaying the focus object in the focus state manner can be displaying a focus frame enclosing the focus region. As an example, in response to receiving a long press operation on the power supply key of the terminal device, it can be determined that the focus control instruction corresponding to the power supply key and the long press operation is displaying the focus regions in the focus state manner one by one along a designated direction, such that the displaying sequence of displaying the plurality of focus regions in the focus state manner can be determined based on the designated direction and the focus region that is displayed in the focus state. The focus frame is displayed on the focus regions sequentially based on the displaying sequence.
As another example, in response to receiving a long press operation on the volume increasing key of the terminal device, it can be determined that the focus control instruction corresponding to the volume increasing key and the long press operation is displaying a plurality of focus controls within a focus region in the focus state manner in turn along a designated direction (such as downward or rightward). Based on the designated direction (such as downward or rightward) and the focus region that is displayed in the focus state manner currently, the plurality of focus objects can be displayed in the focus state manner sequentially in a such way that a focus control within the focus region is quickly selected and the focus frame moves on the focus controls along the designated direction (such as downward or rightward).
As still another example, in response to receiving a long press operation on the volume reducing key of the terminal device, it can be determined that the focus control instruction corresponding to the volume reducing key and the long press operation is displaying a plurality of focus controls within a focus region in the focus state manner in turn along a designated direction (such as leftward or upward). Based on the designated direction (such as leftward and upward) and the focus region that is displayed in the focus state manner currently, the plurality of focus objects can be displayed in the focus state manner sequentially in a such way that a focus control within the focus region is quickly selected and the focus frame moves on the focus controls along the designated direction (such as leftward or upward).
In some examples, the way of displaying the focus object in the focus state manner may be for example highlighting the focus object, displaying a focus frame enclosing the focus object, proportionally magnifying the focus object or the like. The way of displaying the focus object in the focus state manner is not limited in the disclosure. In actual applications, the way of displaying a focus object in the focus state manner can be determined based on the actual requirements.
In some examples, the focus object is a focus region. When the focus control instruction is a confirmation instruction on a focus region, a specified focus control within the focus region may be determined based on the confirmation instruction and displayed in the focus state manner. Therefore, the key operation instruction from the terminal device can be used to conveniently control to display the specified focus control within the focus region on the current display interface in the focus state manner, which avoids a situation that the focus regions on the current display interface cannot be controlled when the hardware keys of the in-vehicle system cannot work improperly.
As an example, displaying the focus object in the focus state manner is displaying the focus object through the focus frame, i.e., displaying a focus frame enclosing the focus object to achieve the displaying of the focus object in the focus state manner. In response to receiving a double click operation on the power supply key of the terminal device, it can be determined that the key operation instruction includes the key identifier of the power supply key and the double click manner. In a case that the focus control instruction corresponding to the key identifier of the power supply key and the double click manner is the confirmation instruction on the focus region, the simulation that the focus control within the focus frame of the current focus region is clicked on is achieved.
As another example, in response to receiving a double click operation on the volume increasing key of the terminal device, it can be determined that the key operation instruction includes a key identifier of the volume increasing key and the double click manner. In a case that the focus control instruction corresponding to the key identifier of the volume increasing key and the double click manner is the confirmation instruction on a focus region, the simulation that the focus control within the focus frame of the current focus region is clicked on is achieved.
As still another example, in response to receiving a double click operation on the volume reducing key of the terminal device, it may be determined that the key operation instruction includes the key identifier of the volume reducing key and the double click manner. In a case that the focus control instruction corresponding to the key identifier of the volume reducing key and the double click manner is the confirmation instruction on a focus region, the simulation that a focus control within the focus frame of the current focus region is clicked on is achieved.
It is to be noted that, at least one focus control may be arranged in each focus region, such that in response to receiving the confirmation instruction on a focus region, a corresponding focus control within the focus region is displayed in the focus state manner. The corresponding focus control may be any one of the at least one focus control within the focus region.
In some examples, the focus object is a focus control within a focus region. When it is determined that the focus control instruction is a clicking instruction on a focus control based on the key operation instruction, a corresponding operation can be performed on the focus control based on the clicking instruction. Therefore, the key operation instruction from the terminal device can be used to control the focus control on the current display interface. That is, the control of the focus control on the current display interface through the key operation of the terminal device is achieved.
The focus control is a control within a focus region, which may be in any forms. For example, the focus control is a button, a textbox, or the like.
In some example, the focus control instruction may be a focus state switching instruction. In this case, a first focus object that is in the focus state currently is acquired, a second focus state is determined based on the focus state switching instruction and the first focus object, and the focus object displayed in the focus state manner is switched from the first focus object to the second focus object. That is, after the second focus object is determined, the second focus object instead of the first focus object is displayed in the focus state manner. Thus, the key operation instruction from the terminal device can be used to control the switching between the focus objects on the current display interface. That is, the control of switching the focus objects on the current display interface through the key operation of the terminal device is achieved.
In some examples, the focus object is a focus region and in this case, displaying the focus object in the focus state manner is displaying a focus frame enclosing the focus region. In response to receiving a single click operation on the power supply key of the terminal device, it can be determined that the focus control instruction is the focus state switching operation based on the power supply key. A switching operation direction can be determined based on the single click operation, a second focus region can be determined based on the first focus region that is displayed in the focus state manner currently and the focus state switching direction, and the focus frame switches from the first focus region to the second focus region. That is, the focus frame enclosing the second focus region is displayed and the focus frame enclosing the first focus region is not displayed.
As another example, in the case that the focus frame enclosing a first focus control within a focus region is displayed, in response to monitoring a single click operation on the volume increasing key of the terminal device, it may be determined that the focus control instruction is the focus state switching instruction based on the volume increasing key. The switching direction (such as downward or rightward) can be determined based on the single click operation. The second focus control can be determined based on the first focus control that is displayed currently in the focus state manner and the switching direction. The focus frame is switched from the first focus control to the second focus control. It is understandable that the second focus control is located on the right or below the first focus control.
As another example, in the case that a focus frame enclosing a first focus control within a focus region is displayed, in response to monitoring a single click operation on the volume reducing key of the terminal device, it can be determined that the focus control instruction is the focus state switching instruction based on the volume reducing key. The switching operation (such as upward or leftward) can be determined based on the single click operation. A second focus control can be determined based on the first focus control that is currently displayed in the focus state manner and the switching direction. The focus frame is switched from the first focus control to the second focus control. It is understandable that the second focus control is located on the left or above the first focus control.
At block 204, the processed display interface is projected on a display screen of the in-vehicle system.
With the method for controlling an interface focus on a display interface according to embodiments of the disclosure, the focus control instruction on a focus object on a current display interface is determined based on the key identifier and the corresponding key manner from the terminal device, such that the focus object is controlled and the processed display interface is projected on the display screen of the in-vehicle system. Therefore, the key operation instruction from the terminal device can be used to process the current display interface and the processed display interface can be synchronized to the display screen of the in-vehicle system. In this way, the focus state function of the in-vehicle system can be achieved efficiently and agilely through the hardware keys of the phone. In addition, the in-vehicle system that does not support the focus state or the in-vehicle system whose hardware keys related to the focus state can achieve the focus state function through the hardware keys of the terminal device, which facilitates use.
On the basis of the above embodiments, in a process of displaying the focus object on the current display interface in the focus state manner based on the key identifier and the key manner, a displaying duration corresponding to the focus object can be determined based on the key identifier and the key manner, such that a duration of displaying the focus object in the focus state can be controlled based on the displaying duration corresponding to the focus object. Therefore, the control of the duration of displaying the focus object in the focus state manner is achieved based on the key operation on the terminal device.
In some embodiments, the display interface may be divided into five focus regions based on a layout and an interaction definition, including a top region, a bottom region, a left region, a right region, and a center region.
Each focus region illustrated in
In some embodiments, in order to solve a problem that the in-vehicle system controls the displaying of the focus object in the focus state manner through the hardware components (such as a knob or a touchpad), which causes a high dependency on hardware components and self-support by the hardware component of the in-vehicle system, in the disclosure, the simulation of functions achieved by the hardware keys of the in-vehicle system can be implemented through the hardware keys (such as the volume increasing key, the volume reducing key, and the power supply key) of the terminal device, as illustrated in
In some embodiments, after the key operation instruction from the terminal device is acquired, the key operation instruction may be sent to the in-vehicle system. The in-vehicle system may simulate operation information of a corresponding hardware key based on the key operation instruction, generate a corresponding control instruction based on the operation information of the hardware key of the in-vehicle system, and send the control instruction to the terminal device. The terminal device performs focus state control on the current display interface based on the control instruction sent by the in-vehicle system, and synchronize the processed display interface to the in-vehicle system such that the processed display interface is synchronously displayed on the display screen.
In some embodiments, the display interface is processed based on the key identifier and the corresponding key manner included in the key operation instruction. The processing of the display interface is described as follows. In an implementation, in response to detecting that the volume increasing key is single clicked, a focus control within a focus region is displayed in the focus state manner by displaying a focus frame enclosing the focus control. Every time the single click on the volume increasing key is detected, the focus frame moves to a next focus control slowly rightwards or downwards, and the focus frame can move circularly through of all focus controls within the focus frame. In response to detecting that the volume increasing key is long pressed, a focus control is quickly selected and the focus frame moves quickly on the focus controls rightwards or downwards. In response to detecting that the volume increasing key is double clicked, clicking on a corresponding focus control within the focus frame is simulated.
In another implementation, in response to detecting that the volume reducing key is single clicked, a focus control within a focus region is display in the focus state manner by displaying a focus frame enclosing the focus control. Every time the single click on the volume reducing key is detected, the focus frame moves to a next focus control slowly leftwards or upwards, and the focus frame can move circularly through of all focus controls within the focus frame. In response to detecting that the volume reducing key is long pressed, a focus control is quickly selected and the focus frame moves quickly on the focus controls leftwards or upwards. In response to detecting that the volume reducing key is double clicked, clicking on a corresponding focus control within the focus frame is simulated.
In still another implementation, in response to detecting that the power supply key is single clicked, a focus region is displayed in the focus state manner by displaying a focus frame enclosing the focus region. Every time the single click on the power supply key is detected, the focus frame moves to a next focus region included in the current display interface slowly rightwards or downwards, and the focus frame can move circularly through of all focus regions included in the current display interface. In response to detecting that the power supply key is long pressed, a focus region on the current display interface is quickly selected. In response to detecting that the power supply key is double clicked, a currently selected focus region is accessed and the focus frame moves to a focus control within the currently selected focus region.
