Description

Data processing method and electronic equipment

Technical Field

The embodiment of the application relates to the technical field of electronic equipment, in particular to a data processing method and electronic equipment.

Background

The user can control the intelligent wrist-watch to switch and display different dials, acquires different experiences.

In some scenarios, two or more hands with the same center of rotation may be included in the dial of the smart watch for information display. For example, a dial may include an hour hand, a minute hand, and a second hand for displaying time information. The hour hand, minute hand and second hand can rotate with the same rotation center.

The intelligent watch can check the rotation centers of the hour hand, the minute hand and the second hand in the process of rendering the dial interface according to the data file of the dial, and determine whether the rotation centers of the hands are coincident.

In some dial data files, the coordinate parameters of the rotation center of each pointer can be calibrated by taking the coordinate parameters as a reference. In this way, in order for the smart watch to determine whether the rotation centers of the hands overlap, it is necessary to transform the rotation center coordinates of the hands into a uniform watch-based coordinate system based on the data file.

Since the data file does not strictly correspond to the size of the smart watch in which the dial is actually used, the coordinates of the centers of rotation of the hour hand, minute hand, and second hand in the watch-referenced coordinate system often differ.

In this way, the smart watch discards one or more pointers, only renders part of the pointers, and obtains the corresponding dial interface. And thus loss of one or more pointers occurs on the displayed dial interface.

Disclosure of Invention

The application provides a data processing method and electronic equipment, which can enable the rotation center coordinates of each pointer under a watch coordinate system to be consistent by updating the rotation area parameters of each pointer, thereby ensuring that each pointer can be completely rendered and avoiding the problem of pointer loss after dial plate application.

In order to achieve the technical purpose, the application adopts the following technical scheme:

in a first aspect, a data processing method is provided, the method being applied to a first electronic device, the method comprising: the first electronic device obtains a first data file, wherein the first data file corresponds to a first display interface, and the first display interface comprises a plurality of display objects. The first electronic device determines, according to the first data file, that a first pointer and a second pointer are included in the plurality of display objects, wherein the rotation centers of the first pointer and the second pointer are the same. The first electronic device configures a first rotation region parameter of the first pointer in the first data file. The first electronic device configures a second rotation region parameter of the second pointer in the first data file. The first rotation region parameter is used to identify a rotation region of the first pointer on the first display interface. The second rotation region parameter is used for identifying a rotation region of the second pointer on the first display interface. The first pointer and the second pointer, which are determined according to the first rotation area parameter and the second rotation area parameter, have the same coordinates in the same coordinate system. And the first electronic equipment renders and displays the first display interface according to the configured first data file.

Based on the scheme, the first electronic device can update the rotation area parameters of the first pointer and the second pointer so that the coordinates of different pointers rotating along the same rotation center are the same under the same coordinate system (such as the coordinate system corresponding to the first electronic device). Therefore, the pointers can be prevented from being discarded in the rendering process of the first display interface, and the complete display of all the pointers is ensured.

Optionally, the first data file includes a background image of the first display interface, a picture resource of the first display interface, and a configuration file of the first display interface. Wherein, the background graphic and the picture resource can be used for rendering the first display interface. The configuration file may identify the size and location of the individual display objects.

Optionally, the picture resource of the first display interface includes a first image and a second image, where the first image corresponds to the first pointer and the second image corresponds to the second pointer. The first image may be an image corresponding to a circumscribed rectangle of the first pointer. The second image may be an image corresponding to a circumscribed rectangle of the second pointer.

Optionally, the configuration file of the first display interface includes: a first coordinate and a second coordinate. The first coordinate is a coordinate of a rotation center of the first pointer under a first coordinate system, and the first coordinate system corresponds to the first image. The second coordinate is a coordinate of a rotation center of the second pointer in a second coordinate system corresponding to the second image. It is understood that the first and second coordinates may be established based on the image coordinate systems of the first and second pointers, respectively. In this way, the rotation center of each pointer can be calibrated even if the size of the first electronic device actually using the interface is not known.

Optionally, the first coordinate system corresponds to the first image, including: the two coordinate axes of the first coordinate system are perpendicular to each other, and the two coordinate axes of the first coordinate system are respectively overlapped with a first straight line and a second straight line, wherein the first straight line and the second straight line are the straight lines where two adjacent edges of the first image are located. The second coordinate system corresponds to the second image, and includes: the two coordinate axes of the second coordinate system are perpendicular to each other, and the two coordinate axes of the second coordinate system are respectively overlapped with a third straight line and a fourth straight line, wherein the third straight line and the fourth straight line are the straight lines where two adjacent edges of the second image are located.

Optionally, the configuration file of the first display interface further includes: the first pointer has a third rotation region parameter in a third coordinate system. A fourth rotation region parameter of the second pointer in the third coordinate system. The third coordinate system corresponds to the first electronic device. It may be appreciated that the configuration file may include scan areas corresponding to the first pointer and the second pointer, respectively. And because the configuration file and the first electronic device have no absolute corresponding relation, the rotation centers of the third rotation region and the fourth rotation region corresponding to the first electronic device may be combined in a complementary way, so that the problem of pointer loss in the subsequent rendering process is generated.

Optionally, the first electronic device includes a display screen, and the third coordinate system corresponds to the first electronic device, including: the two coordinate axes of the third coordinate system are mutually perpendicular, and the two coordinate axes of the third coordinate system are respectively tangent to the display screen.

Optionally, before the first electronic device configures the first rotation area parameter of the first pointer in the first data file, the method further includes: the first electronic device determines the first rotation region parameter according to the first coordinate and the resolution of the first electronic device. The first electronic device configures a first rotation area parameter of the first pointer in the first data file, including: the first electronic device replaces the third rotation region parameter with the first rotation region parameter.

Optionally, before the first electronic device configures the second rotation area parameter of the second pointer in the first data file, the method further includes: the first electronic device determines the second rotation region parameter according to the second coordinate and the resolution of the first electronic device. The first electronic device configures a second rotation area parameter of the second pointer in the first data file, including: the first electronic device uses the second rotation region parameter to replace the fourth rotation region parameter.

Thus, the rotation area parameters of the respective pointers are accurately determined in combination with the actual parameters (such as resolution) of the first electronic device. By replacing the original parameters in the configuration file with the new rotation area parameters, the rotation centers of the pointers determined according to the new rotation area parameters in the first electronic device can be mutually overlapped, so that complete display of the pointers is ensured.

Optionally, the configuration file of the first display interface includes: the first pointer is a first type identifier of the first pointer, and the first pointer is a first distinguishing identifier of the first pointer. And a first type identifier of the second pointer, a second distinguishing identifier of the first pointer. Wherein the first type identifier is used to indicate that the corresponding object is a pointer. The first distinguishing identifier and the second distinguishing identifier are different.

Detailed Description

The terms "first" and "second" are used below for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature. In the description of the present embodiment, unless otherwise specified, the meaning of "plurality" is two or more.

Currently, a user may use multiple electronic devices simultaneously in order to obtain different intelligent service experiences through different electronic devices.

By way of example, the plurality of electronic devices may include a cell phone, a smart watch, and the like.

Reference is made to fig. 1. In some embodiments, the mobile phone may establish a communication connection with a smart watch (hereinafter simply referred to as a watch) for data transmission. For example, the communication connection may be a Bluetooth connection based on the Bluetooth (r) protocol.

Based on the Bluetooth connection, the mobile phone can acquire information such as movement data of a user from the watch. The mobile phone can also control the watch to carry out configuration of various parameters through the Bluetooth connection.

For example, the mobile phone may control the watch to perform configuration of various parameters (such as a dial) through an Application (APP) installed in the mobile phone under the operation of the user.

As an example, taking the case of a mobile phone controlling a watch through "sports health" APP to replace a different dial.

Referring to fig. 2, an interface diagram of a mobile phone under the control of a user to configure the dial of a wristwatch is shown.

As shown in fig. 2, an icon 202 of "sports health" APP may be displayed on an interface 201 of the handset. The user may input an indication to the icon 202 for instructing the electronic device to run the "sports health" APP.

Illustratively, the user may input operation 203 to icon 202. For example, the operation 203 may be a click or touch operation on the icon 202.

In response to operation 203, the mobile phone may start running the "sports health" APP and switch to display the interface 204 corresponding to the "sports health" APP. As shown in fig. 2, in interface 204, a smart device may be included that has established a bluetooth connection with a handset. In this example, control 205 in interface 204 corresponds to watch 1. Then, through this control 205, the user can know that the current wristwatch 1 has established a bluetooth connection with the mobile phone, and can configure the wristwatch 1 through the mobile phone.

As shown in fig. 2, dial market controls 206 may also be included in interface 204. A plurality of different dials may be included in the dial market for user selection. It is understood that the data files of each dial in the dial market may be stored in a corresponding cloud server of the "dial market". When the mobile phone downloads the data files of one or more dials, the data files of the corresponding dials can also be stored in the mobile phone.

The mobile phone can obtain the data file of the dial plate wanted by the user from the cloud server or locally under the instruction of the user, and instruct the watch to switch and display the dial plate.

In different implementations, the user may instruct the mobile phone to configure the dial of the watch through a combination of operations.

In some implementations, the example is that the handset currently has a bluetooth connection established only with the watch 1. The mobile phone can then perform an alternate configuration of the dial of the watch 1, under the direction of the user as included in fig. 2.

As shown in fig. 2, the user may enter an operation 207 into a corresponding region of the dial market control 206, instructing the handset to enter a dial selection interface. For example, the operation 207 may include a click operation on the control 206 of the disk market. In response to this operation 207, the handset may switch the display interface 208. A plurality of display sub-areas corresponding to the dial plates may be included in the interface 208. For example, the interface 208 may include a display sub-area 209 corresponding to the dial 2, a display sub-area corresponding to the dial 1, and the like. The user may enter an operation 210 on the display sub-area corresponding to the dial that he wants to replace, indicating that the handset enters the detail interface of the dial. For example, the user may enter operation 210 into the display sub-area 209 corresponding to dial 2, instructing the handset to enter the detail interface corresponding to dial 2. In response to this operation 210, the handset may switch the display interface 211. The interface 211 may be a detail interface corresponding to the dial 2. The interface 211 may include a preview image 212 of the dial 2, and information such as a dial profile corresponding to the dial 2. In this interface 211, a button 213 may also be included. The user can input an operation 214 to the button 213 in case it is determined that the dial 2 is intended to be used on the wristwatch 1. Taking operation 214 as an example of a click operation on button 213. In response to the click of the button 213, the mobile phone can acquire the data file of the dial 2. For example, the mobile phone can search locally for the data file of dial 2 that has been downloaded. For another example, the mobile phone may obtain the data file of the dial 2 from the cloud server corresponding to the dial market. The mobile phone can then transmit the data file of the dial 2 to the watch 1 via a bluetooth connection, so that the watch 1 displays the dial 2 instead.

In other implementations, the user may also control the mobile phone to switch and display the dial of the watch 1 through a configuration interface corresponding to the "watch 1".

For example, refer to fig. 3 in conjunction with fig. 2. On the interface 204, the user may enter an operation 301 into the control 204 corresponding to watch 1, indicating that the handset enters the configuration interface of watch 1. In response to operation 301, the handset may switch the display interface 302. In the interface 302, information about the wristwatch 1 may be included. For example, the dial preview being used by the wristwatch 1 (as shown in fig. 3, the watch 1 is using the dial 1). As another example, the current power of the wristwatch 1.

In the interface 302, a control 303 corresponding to the dial market may also be included. The user may enter operation 304 into this control 303 when he wants to switch the dial on the watch 1. Taking operation 304 as an example, a clicking operation on the corresponding region of control 303. In response to the clicking operation of the pair of controls 303, the mobile phone can switch display of a plurality of dial previews that can be applied to the wristwatch 1. For example, the handset may switch to display the interface 305 as shown in fig. 3. One or more dial preview controls that can be applied to the watch 1 may be included in this interface 305. For example, controls 306 corresponding to dial 2 may be included in the interface 305. The user may enter operation 307 on control 306 in the event that he wishes to use the dial 2 on a watch. In response to operation 307, the handset may switch the detail interface 308 corresponding to the display dial 2. In some implementations, this interface 308 may correspond to the interface 211 shown in fig. 2. Buttons 309 may be included in the interface 308. When the user determines that the display on the wristwatch 1 is to be switched using the dial 2, an operation 310 may be entered on the button 309. In response to operation 310, the handset may obtain the data file for dial 2. The mobile phone can then transmit the data file of the dial 2 to the watch 1 via a bluetooth connection, so that the watch 1 displays the dial 2 instead.

Thus, by the mechanism shown in fig. 2 or 3, the mobile phone can perform configuration of dial switching display of the wristwatch under control of the user.

As an example, fig. 4 provides an example of a scheme flow for controlling the wristwatch to switch the display dial 2 by the mobile phone. Taking a data file of the mobile phone, which is not stored with the dial 2, as an example. The flow may be triggered by the handset receiving operation 214 as shown in fig. 2 or operation 310 as shown in fig. 3.

As shown in fig. 4, the scheme may include:

s401, the mobile phone downloads the data file of the dial 2.

Illustratively, the handset may determine that the data file for dial 2 is not stored locally after receiving the user input at operation 214 or operation 310. In conjunction with the descriptions of fig. 2 and 3, in this example, the mobile phone may obtain the data file of the dial 2 from the cloud server of the dial market.

S402, the mobile phone sends the data file of the dial 2 to the watch.

For example, the mobile phone may send the data file of dial 2 to the watch via a bluetooth connection.

S403, the watch determines the initial positions of the pointers in the dial 2 according to the received data file.

The initial position of the pointer may be the position on the watch display screen when the pointer points to 12 o' clock.

In connection with the example of fig. 2 or 3, the current time displayed by the dial 2 through the "hour hand", "minute hand" and "second hand" is taken as an example.

The wristwatch can determine, after receiving the data file of the dial 2, that at least one pointer is included in the dial 2. The wristwatch can then determine the initial positions of the three hands in the dial 2, respectively, from the data file of the dial 2.

S404, the watch draws and displays the dial 2 corresponding to the current time according to the initial positions of the pointers in the dial 2 and the current time.

It can be understood that after determining the initial positions of the three pointers on the display screen of the watch, the watch can determine the rotation angles of the pointers corresponding to the current time by taking the initial positions as the initial positions according to the current time.

For example, the current time is 12:00:00. the watch can then determine the rotation angle of the hour hand, minute hand, and second hand to be 0 degrees.

For another example, the current time is 3:30:00. then the watch may determine that the rotation angle of the hour hand may be 105 degrees, the rotation angle of the minute hand may be 180 degrees, and the rotation angle of the second hand may be 0 degrees.

The watch can draw the display image data corresponding to the current time according to the rotation angle and the initial position by combining the background image of the dial 2 (such as the background image of the dial 2 shown in fig. 2 or 3). Based on the display image data, the wristwatch can switch the dial 2.

As an example of the scheme shown in fig. 4, the wristwatch may determine, after receiving the data file of the dial 2, what is currently to be displayed according to the received data file. The content of the display may include: the time display by three hands (such as an hour hand, a minute hand, and a second hand) corresponds to the dial 2 and the current time.

In the application, the process of determining the content to be displayed currently by the watch according to the received data file can be realized by analyzing the data file. In this analysis process, the wristwatch needs to determine the coordinates of the rotation center of each pointer in the corresponding coordinate system of the wristwatch display (e.g., the wristwatch coordinate system). The coordinates of the rotation center of the respective pointers may be separately calculated.

In the current implementation, the rotation center of each pointer calculated by the watch according to the data corresponding to each pointer in the received data file may not be identical in the coordinates of the watch coordinate system. In this way, the watch automatically discards one or more pointers when it draws the current display. In this way, after the dial is switched, the hands are lost on the display screen of the wristwatch.

For example, as shown in fig. 5, before the dial is displayed in a switched manner, as shown in 501, the wristwatch may be displayed with dial 1. The dial 1 may display the current time in the form of numerals. After passing through the configuration flow shown in fig. 2 to 4, the wristwatch can switch the display dial 2. The dial 2 can display time by 3 hands. Ideally, the display effect after switching the display may be a time display by 3 pointers as shown at 502 in fig. 5. Whereas when there is a difference in the coordinates of the center of rotation between two or more hands among the hour hand, the minute hand and the second hand, the wristwatch will actually display 503 as shown in fig. 5. I.e., one or more pointers are lost at the interface. In this example, as in fig. 5, only the hour hand is displayed on the display screen of the wristwatch, and the minute hand and the second hand are lost.

This causes a problem of incomplete display when time display is performed based on the pointer.

It will be appreciated that in the above example, the time display is taken as an example in which 3 hands are included in the dial 2 to be switched for display. In other scenarios, a dial to be switched may include 2 or more hands for time display. For similar reasons, there may also be a problem of pointer loss due to the difference in coordinates of the rotation centers of the respective pointers in the watch coordinate system. In other situations, when other data (such as the number of historical steps and the number of current steps) are displayed on the dial through two or more pointers, if the two or more pointers are rotated according to the same rotation center, the coordinates of the rotation centers of the different pointers under the same coordinate system, which are obtained by calculation according to the data corresponding to the different pointers, are different, and then the situation that the pointers are lost may also occur.

In order to solve the above problems, the embodiment of the present application provides a technical solution, which can ensure that the coordinates of the rotation centers of the obtained pointers are respectively calculated to be consistent when a plurality of pointers are displayed in a rotation manner based on the same rotation center. Thereby avoiding the situation of pointer loss caused by different rotation centers.

The following will describe the scheme provided by the embodiment of the present application in detail with reference to the accompanying drawings.

The scheme provided by the embodiment of the application can be applied to the electronic equipment of the user. For example, in some embodiments, the electronic device may include a smart watch, smart bracelet, or the like in a wearable device. In other embodiments, the electronic device may also include portable electronic devices such as augmented reality (augmented reality, AR) devices, virtual Reality (VR) devices, artificial intelligence (artificial intelligence, AI) devices, vehicle devices, smart home devices, and the like.

In a specific implementation process, the electronic device can display information through the pointer under the control of control equipment (such as a mobile phone of a user). For example, the time is displayed by the hour hand, minute hand, and second hand as described above.

In different embodiments, the electronic device may have different compositions.

As an example, referring to fig. 6, a schematic software composition diagram of an electronic device according to an embodiment of the present application is provided.

As shown in fig. 6, in this example, the software composition of the electronic device may have a multi-layered structure. The layers communicate with each other through a software interface. One or more functional modules may be included in the different layers. Functional modules in the multiple layers may be used in conjunction to implement one or more functions of the electronic device.

It is understood that an operating system may be running in the electronic device. For example, the operating system may be based on Is suitable for use in portable electronic devices or wearable electronic devices. As another example, the operating system may be a micro-operating system customized for a wearable electronic device or a portable electronic device.

An operating system running in the electronic device can provide the processing power of the kernel. For example, the operating system may provide storage, tasks, transmission of data in a bus (e.g., interprocess communication (Inter Process Communication, IPC)), task interruption, and the like.

The configuration and operation of the software in the various layers as shown in fig. 6 may be implemented based on the operating environment provided by the operating system running in the electronic device.

As shown in fig. 6, in this example, the electronic device may include an application layer, a framework layer, algorithms and internal libraries, a hardware abstraction layer, and a hardware driver layer.

Wherein the application layer may include a series of application packages. Take an electronic device as an example of a wristwatch. As an example, the application layer of the watch may include an application package for performing watch management, such as device management, OTA upgrade, dial management, and the like. The application layer may also include a map application, a music application, a navigation application, and the like, as well as a variety of third party developer-provided functionality applications. The application layer may also include communication-type applications such as information, contacts, calls, etc. The application layer can also comprise applications supporting interconnection and interworking functions with other devices, such as mobile phone positioning, voice assistants, personal transaction centers and the like. The application layer may also include sports health, wallet applications, manufacturing, and other functional applications.

It is understood that the configuration in the application layer as shown in fig. 6 is only an example. In other implementations, the application layer in the electronic device may include more or fewer applications. So as to support various functions of the electronic device through different application programs.

In the example as in fig. 6, the dial management application can determine specific parameters of the respective elements in the dial to be switched for display from the data file of the dial from the control device by interacting with the control device.

For example, dial 2 in the foregoing example is taken as an example of a dial displayed in a switching manner. The specific parameters of each element in the dial 2 can comprise the initial positions corresponding to the hour hand, the minute hand and the second hand respectively; the rotation center of the hour hand, the minute hand, and the second hand, respectively. Based on the scheme provided by the application, the coordinates of the rotation centers corresponding to the hour hand, the minute hand and the second hand, which are determined by the dial management application, are the same. Thereby avoiding the problem of losing the pointer in the display process caused by different rotation centers of different pointers.

As shown in fig. 6, below the application layer may be a framework layer. The frame layer may also be referred to as a frame layer.

The framework layer provides an application programming interface (application programming interface, API) and programming framework for application programs of the application layer. The application framework layer includes a number of predefined functions.

In this example, the framework layer may provide meta-capability Cross-platform execution environment (ACE) User Interface (UI) frameworks, system base service capabilities, underlying software service capabilities, sports health service capabilities, hardware service capabilities, and the like. Each framework and capability may correspond to an entity or logic module in the framework layer.

The ACE UI framework may include an ACE application development framework. The ACE application development framework can provide various application development logics so as to facilitate software development and design of development designers in the ACE application development framework. The ACE UI framework may also include UI tools (UI kit). The UI tool may provide image rendering processing capabilities. In some embodiments, the UI tool may be used to execute image rendering instructions indicated by an application in the application layer.

For example, after the dial management analyzes the received data file of the dial, the electronic device may be instructed to render the dial image through the UI kit according to the specific parameters of each element in the dial and the image data of each element obtained by the analysis process.

In other embodiments, a touchGFX framework may also be included in the ACE UI framework. the touchGFX framework, which is a graphical user interface (Graphical User Interface, GUI) framework, can execute image rendering instructions issued by applications, either independently or in conjunction with UI tools.

The system basic service capabilities may include communication services and audio services. The communication services may include, among other things, messaging services, conversation services, interworking services, contact services, and the like. The audio services may include music playing services, audio management services, voice broadcasting services, music control services, and the like.

The underlying software service capabilities may include basic services, manufacturing, and device management, among others. The base service may provide log services, file systems, NV management, exception logging, dual-machine communication, memory management, etc. Manufacturing may include manufacturing-related functions. Such as production services, aging services, etc. Device management may include device control, display management, bluetooth management, and the like.

Sports health service capabilities may include sports services and health services. Among other things, athletic services may include exercise services, daily activity services, data store synchronization services, training state assessment services, and the like. Health services may include heart rate services, sleep services, respiratory services, cardiac health services, and the like.

The hardware service capabilities may include various business support capabilities. For example, hardware service capabilities may include location services, bluetooth/bluetooth low energy (Bluetooth low energy, BLE) services, near field communication (Near Field Communication, NFC) services, and the like.

Algorithms and internal libraries may be included under the framework layer. The algorithm and the internal library can comprise a plurality of functional functions and interfaces, and the framework layer is used for realizing corresponding functions by calling the plurality of functional functions and interfaces.

By way of example, the algorithm and internal library may comprise an algorithm library, a base library. The algorithm library may include, among other things, living body detection related algorithm functions, gesture related algorithm functions, and the like. The base library may include bar code correlation algorithm functions, a base C library, and the like.

In this example, the algorithms and internal libraries may also include a communication protocol stack. Protocol data for supporting the communication capabilities of the device may be included in the communication protocol stack. For example, the communication protocol stack may include a bluetooth protocol stack, a BLE protocol stack, and the like.

The hardware abstraction layer, i.e. Hardware Abstract Layer, or simply HAL layer. An abstraction module of one or more entity components may be included in the HAL layer. The application program can realize the calling and the data acquisition of the corresponding entity component by issuing instructions to the abstract module in the entity component.

For example, in this example, a hardware abstraction layer may include a software abstraction module of a board level support package (Board Support Package, BSP), NFC, a liquid crystal display (Liquid Crystal Display, LCD), bluetooth, flash, touch Panel (TP), and other entity components. The hardware abstraction layer can also comprise a hardware abstraction module corresponding to a sensor component arranged in the electronic equipment. For example, acceleration sensor, gyroscope sensor, and other corresponding hardware abstraction modules.

In the example of fig. 6, a hardware driver layer may also be included in the electronic device. The hardware Driver layer may also be referred to as a Driver layer. Drives for one or more hardware components may be included in the hardware driver layer. When an application program needs to call a hardware component arranged in the electronic equipment, an instruction can be issued to a driving module arranged in a corresponding hardware driving layer, so that the driving module can convert the software instruction into an instruction which can be directly transmitted to the hardware component, and control and data transmission of the hardware component are realized.

By way of example, the hardware driver layer may include a BSP driver, an LCD driver, a TP driver, a flash driver, an NFC driver, a bluetooth driver, a sensor driver, and the like.

It should be noted that, the application layer may communicate with the framework layer by calling the framework API. The framework layer may also call a corresponding API implementation when functions that require the calling of algorithms and internal libraries communicate with the kernel layer or hardware abstraction layer. For example, APIs that call the kernel layer may include a CMSIS API, HAI APIs may be used when calling the HAL, and the like.

In connection with the example of fig. 6, taking the electronic device as a watch and the control device as a mobile phone as an example, the switching display scene of the dial plate is illustrated.

For example, the dial management application may invoke a bluetooth/BLE module in the framework layer to establish a bluetooth connection with the control device. After the bluetooth connection is established, the dial-up management application may interact with applications in the control device (such as the sports health application shown in fig. 1) and transmit data through the bluetooth connection.

Taking the dial management in a wristwatch as an example, data or information is transmitted to the sports health application in the cell phone. The dial management application may issue an instruction to the bluetooth/BLE module in the framing layer, which may carry the data or information to be transmitted. The bluetooth/BLE module may call a communication protocol stack, and perform processing such as encapsulation on data or information to be transmitted to obtain a corresponding data packet. The encapsulated packets may be transmitted to a bluetooth module in the HAL layer for downstream transmission of the packets between devices. The Bluetooth module can send the data packet outwards through the antenna corresponding to the Bluetooth transmission link by calling the Bluetooth driver in the hardware driver layer. In this way, the handset can receive the data packet via the data transmission path of the bluetooth connection already established with the watch. The data packet can be transmitted to the sports health application of the mobile phone for analysis processing. The sports health application is thereby enabled to determine, from the parsed data packets, the data or information to be transmitted by the dial management in the watch.

It will be appreciated that dial management in a wristwatch may receive data or information transmitted from a sports health application in a cell phone, as opposed to the procedure described above. For example, the data transmitted by the handset to the dial management may include a data file for the dial in the previous example.

The description and examples of fig. 6 do not limit the electronic device according to the present application. In other embodiments, the electronic device may also have more or less hardware or software components. The embodiment of the application is not limited to the specific composition of the electronic equipment.

The scheme provided by the embodiment of the application can be applied to the electronic equipment shown in fig. 6.

In the following description, the electronic device is taken as a watch, and the control device is taken as a mobile phone to describe the scheme provided by the embodiment of the application.

The scheme provided by the embodiment of the application can support the watch to process the received data file of the dial. The processing may include determining, from the data file, coordinates of a center of rotation of each pointer based on a corresponding coordinate system of the watch display. The coordinates of the centers of rotation of the different pointers may be the same.

The procedure of acquiring a data file of a dial of a wristwatch will be briefly described with reference to fig. 7 and 8. It will be appreciated that this implementation of the scheme of fig. 7 and 8 may correspond to S402 as shown in fig. 4.

In this example, before the watch and the mobile phone transmit the data file of the dial, the data negotiation may be performed according to the scheme shown in fig. 7, so that the watch and the mobile phone unify definition and verification information of the data file of the dial (such as the data file of the dial 2) to be transmitted subsequently.

As shown in fig. 7, the scheme may include:

s701, the mobile phone sends a transmission request A to the watch.

For example, in connection with the description of fig. 2 and 3, the sports health application of the mobile phone may trigger generation of the transmission request a upon receiving the operation 214 or operation 310 of the user.

In some implementations, the transmission request a may include information of a dial ID, version number, etc. of the dial 2.

S702, the watch determines that the dial 2 indicated by the transmission request a is not stored locally.

For example, a dial management application of a wristwatch may receive a transmission request a. The dial management application may query the watch local (e.g. flash memory of the watch) whether the data files of the same dial are stored according to the dial ID, version number, file size, etc. indicated by the transmission request a.

The dial management application of the wristwatch may execute the subsequent S703 in case that it is determined that the data file corresponding to the transmission request a is not stored in the flash memory, so as to acquire the data file of the dial 2 through the mobile phone.

It will be appreciated that in other implementations, the flash memory of the watch may already have stored therein the data file of the dial 2. The dial management application of the wristwatch can then jump to the subsequent display switching step. The specific implementation will be described later. And will not be described in detail herein.

S703, the watch sends a transmission response A to the mobile phone.

In this example, the transmission response a may be used to instruct the handset to transmit the data file of dial 2.

The dial management application of the wristwatch may perform this S703 in the case where it is determined that the data file of the dial 2 is not stored in the flash memory of the wristwatch according to the transmission request a.

S704, the mobile phone transmits file transmission information B to the watch.

By way of example, the file transfer information B may include information of a file size, a file type, a dial ID, a version number, and the like of a dial (e.g., dial 2) to be transferred.

S705, the watch profile transmits the unique identifier f_id.

S706, the watch sends the unique file transmission identifier f_ID to the mobile phone.

In this example, the dial management application of the wristwatch can, after receiving the transmission information B, configure the dial 2 with a unique identifier that is applied in the subsequent data file transmission process. For example, the file transfer unique identifier of the dial 2 may be configured as f_id.

It will be appreciated that in a bluetooth connection between a wristwatch and a handset, there may be transmission of data or information for multiple services. The dial management application of the wristwatch can distinguish between different data or information by configuring different file transmission unique identifiers, and thus the corresponding file transmission unique identifiers (such as f_id) are carried in the related transmission process for the same data or information (such as the data file of the dial 2), so that the motion health application of the mobile phone and the dial management application of the wristwatch can clearly and definitely determine that the currently received data is the data file corresponding to the dial 2.

S707, the mobile phone sends verification information to the watch.

This verification information may be used, for example, for verification of the received file information of dial 2 by the dial management application of the subsequent wristwatch.

In some embodiments, the mobile phone may transmit the verification information while carrying the file transmission unique identifier (e.g., f_id) corresponding to the dial 2. So that the watch makes sure that the verification information can be used for verifying the data file of dial 2.

S708, the watch receives and stores the check information corresponding to the f_ID.

For example, the dial management application of the wristwatch may store the verification information in the flash memory of the wristwatch after receiving the verification information. In some embodiments, the dial management application of the wristwatch may configure a corresponding storage space for the data file of the dial 2 in the flash memory after transmitting the displacement identifier for the data file configuration file of the dial 2 in S705, so as to store the data file corresponding to the dial 2.

Then in this S708, the dial management application of the wristwatch may store the received verification information in the corresponding storage space of the data file of this dial 2, so as to facilitate the subsequent accurate call.

Thus, by implementing the scheme shown in fig. 7, the watch and the mobile phone can determine the unique file transmission identifier and the verification information of the data file of the dial 2, and complete the data negotiation before the data file transmission.

In some embodiments, the sports health application of the mobile phone and the dial management application of the wristwatch may perform file transmission of the data file of the dial 2 according to the scheme shown in fig. 8 after the data negotiation flow shown in fig. 7.

For example, as shown in fig. 8, the data transmission process may include:

s801, the mobile phone sends a file transmission rule C and f_ID to the watch.

It will be appreciated that during data transfer between devices, the transferred data may include frame header, valid data segment, etc. Under different file transmission rules, the positions of the frame header and the valid data segment in the data segment can be different.

In this example, the sports health application of the cell phone may send a file transfer rule C to the watch that a file (e.g., a data file of dial 2) is to be transferred. So that the dial management application of the wristwatch can receive the data file of the dial 2 according to the file transmission rule C.

In connection with the foregoing description of S706, during the data transmission process between the mobile phone and the watch related to the data file of the dial 2, the corresponding unique file transmission identifier (such as f_id) may be carried, so that the data receiver can know that the current information or the data is the data or the information related to the data file of the dial 2.

S802, the watch determines to transmit the file corresponding to the f_ID by using the file transmission rule C.

The f_id corresponding file may be a data file of the dial 2.

For example, after determining that the data file of the dial 2 can be transmitted using the file transmission rule C, the dial management application of the wristwatch may feed back a corresponding response message to the mobile phone, so that the mobile phone starts to transmit the data file of the dial 2 to the wristwatch according to the file transmission rule C.

It should be noted that, in different implementations, the data file of the dial 2 may be sent at one time or may be sent in segments.

Taking the mobile phone to send the data file of the dial 2 in a segmented mode as an example.

After S802 is executed, the dial management application of the wristwatch may also send a message to the mobile phone, for indicating information such as a size, a data length, etc. of each data segment during the data file transmission process of the dial 2. For example, the message may be transmitted in combination with a response message corresponding to the watch acknowledging the transmission of the data file of dial 2 using file transmission rule C.

In response to the message, the handset may send the data file of dial 2 to the watch based on the negotiated data segment size and data length.

S803, the handset sends the data file D of dial 2, and f_id, to the watch.

S804, the watch receives and stores the data file D of the dial 2 at the position corresponding to the f_ID.

In this way, the dial management application of the wristwatch can acquire the data file corresponding to the f_id through one or more data transfers. If the f_id corresponds to the data file of the dial 2, the watch may sequentially store the data carrying the f_id identifier in the storage space of the flash memory configured for the f_id in the received data.

In this example, after completing receiving the data file corresponding to the f_id (e.g., data file D), the wristwatch may verify the data file D, thereby determining the integrity of the received file.

In some embodiments, the verification process may be performed based on the verification information acquired in S708 as shown in fig. 7.

S805, the watch checks the data file D according to the checking information.

S806, the watch sends a file transmission completion instruction and f_ID to the mobile phone.

Thus, by executing the above-described S801 to S806, the wristwatch can store the complete data file D of the dial 2 in the storage space configured for f_id in the flash memory. The flow then proceeds as follows S807.

The explanation in S702 is combined. In some embodiments, the data file D of the dial 2 may already be stored in the flash memory of the watch. Then, the dial management application of the watch can feed back corresponding information to the mobile phone so that the mobile phone knows that the data file of the dial 2 is not required to be transmitted any more. In this scenario, after receiving the information transmitted by the wristwatch indicating that the wristwatch stores the data file D, the mobile phone performs the following S807 so that the wristwatch performs the switching display of the dial 2.

S807, the mobile phone transmits a dial application instruction, and f_id, to the wristwatch.

In this example, the handset may trigger generation of the dial application indication upon receiving a file transfer completion indication from the watch. The dial application indication may be used to trigger a process by which the watch replaces the current dial for display according to the received data file of the dial.

S808, the watch draws and switches the display dial 2 according to the data file D stored in the position corresponding to the f_id.

For example, in the case where the dial management application of the wristwatch may receive an indication of the dial application, the data file D may be obtained from a storage space corresponding to a file transmission unique identifier (e.g., f_id) corresponding to the indication.

In some embodiments, the dial management application of the wristwatch may obtain the data file D in response to the dial application instruction from the mobile phone, and parse the data file D. It will be appreciated that the data file D may be a data file corresponding to the dial 2.

In connection with the description of fig. 6, in the present application, the parsing process of the data file D may be performed by a dial management application installed in an application program of the wristwatch. In some embodiments, the dial management application may perform both parsing of the data file and the switching operation in the background. In this way, the user can realize the automatic switching from the dial 1 to the dial 2 without any operation on the wristwatch.

In the embodiment of the application, the dial management application can acquire the specific parameters of each element corresponding to the dial 2 through analysis processing of the data file D.

For example, as shown in fig. 9, the dial management application may obtain a background image corresponding to the dial 2, a picture resource of the dial 2, a configuration file of the dial 2, and the like through analysis processing of the data file D.

As an example, fig. 10 provides a specific example of a background image, picture resources, and configuration file of the dial 2.

As shown in fig. 10, the background image of dial 2 is shown as 1001. The background image of the dial 2 may include a background at the time of displaying the dial 2. For example, in this example, the context of dial 2 may include the textual identifications at 12 o 'clock, 3 o' clock, 6 o 'clock, and 9 o' clock, as well as the scale identifications for each whole point. It will be appreciated that the background image of the dial 2 may be unchanged in the dial 2 based display at different times. For example, background images as shown in 1001 are used.

1002 in fig. 10 provides an example of a picture resource for dial 2.

In this example, the dial 2 may display the current time in the form of a pointer. For example, the hands may include an hour hand, a minute hand, and a second hand. The length of the hour hand is smaller than that of the minute hand. The display effect of the second hand may be different from that of the minute hand and the hour hand. For example, the hands of the minute hand and the hour hand may be the same or similar in width, differing only in length. And the width of the second hand may be smaller than the minute hand or the hour hand, and the length of the second hand may be different from the hour hand or the minute hand.

By analyzing the data file D, the dial management application can acquire images corresponding to the hour hand, minute hand, and second hand in the dial 2. For example, the image of the hour hand, the image of the minute hand, and the image of the second hand may be 3 png format images, respectively.

Taking the image of the hour hand as an example. The image of the hour hand may include elements of the hour hand, the end of rotation of the hour hand, etc. The rotation end can comprise a rotation center 1 corresponding to the hour hand, and the hour hand can rotate along the rotation center 1 according to the included angle between the current time and 12 o' clock at different moments so as to stay at the position corresponding to the current moment for display.

The image size of the hour hand may be the smallest image including the element corresponding to the hour hand. For example, as shown at 1002, the image of the hour hand may be a rectangle, which may be a circumscribed rectangle of the element of the hour hand, the rotational end of the hour hand, or the like. In some embodiments, the long side of the image of the hour hand may be parallel to the long side of the hour hand.

Similar to the hour hand, the dial management application may also acquire an image of the second hand as well as an image of the minute hand. In the following examples, the rotation center of the minute hand is taken as the rotation center 2, and the rotation center of the second hand is taken as the rotation center 3.

The dial management application can also acquire the configuration files corresponding to the hour hand, the minute hand and the second hand through the analysis processing of the data file D.

As shown in 1003 of fig. 10, for any one pointer, its corresponding profile may include an identifier, a rotation area parameter under the watch coordinate system, and the coordinates of the rotation center of that pointer under its own image coordinate system.

Illustratively, an hour hand is taken as an example. The configuration file corresponding to the hour hand may include an identifier of the hour hand, a rotation area parameter of the hour hand in a watch coordinate system, and coordinates of the rotation center of the hour hand in an image coordinate system (such as an hour hand image coordinate system) of the hour hand.

Similarly, take a minute hand as an example. The configuration file corresponding to the minute hand may include an identifier of the minute hand, a rotation area parameter of the minute hand under the watch coordinate system, and a coordinate of a rotation center of the minute hand under an image coordinate system (such as a minute hand image coordinate system) of the minute hand.

Taking a seconds hand as an example. The configuration file corresponding to the seconds hand may include an identifier of the seconds hand, a rotation area parameter of the seconds hand in the watch coordinate system, and a coordinate of a rotation center of the seconds hand in an image coordinate system that is itself (such as the seconds hand image coordinate system).

Specific parameters of each profile are described below.

Referring to fig. 11, the identifier of the element in the dial may include a type identifier and a distinguishing identifier. In some embodiments, the type identifier may be identified by draw_type. The discrimination identifier may be identified by value_type.

Wherein the type identifier may be used to indicate the type of the element in the current dial. In different implementations, the types of elements may include: literal, numeric, pointer, etc. In the foregoing example, the current time is displayed by a number in the dial 1, and then the type of the corresponding element may be a number. In this example, the current time is displayed by a pointer in the dial 2, and then the types of elements of the hour hand, minute hand, and second hand may be the pointer.

For example, the draw_type of the hour hand, minute hand, and second hand may be configured as "hand_res" for indicating that the types of the elements of the hour hand, minute hand, and second hand corresponding to the dial 2 are "hands".

The distinguishing identifier may be used to uniquely correspond to an element in the indicator current dial. For example, hands and seconds hands as different display elements may have different distinguishing identifiers.

For example, the value_type of the hour hand may be configured to 150, the value_type of the minute hand may be configured to 153, the value_type of the second hand may be configured to 154, and the like.

In this example, the configuration file of the pointer may also include the rotation area parameters of the pointer in the watch coordinate system.

First, a watch coordinate system is exemplified.

Taking a display screen of a watch as an example. Referring to fig. 12, the x-y plane corresponding to the watch coordinate system may coincide with the plane in which the watch display screen is located. The two axial directions corresponding to the watch coordinate system can be tangential to the watch display screen respectively.

For example, in the example of fig. 12, the plane on which the display screen of the wristwatch is located coincides with the paper surface, and the watchbands on both sides of the display screen of the wristwatch are located directly above and directly below the display screen, respectively. The x-axis of the watch coordinate system may then correspond to the upper tangent of the display screen, perpendicular to the direction of extension of the wristband, the positive x-axis being directed towards the watch display screen. Correspondingly, the y-axis of the watch coordinate system may correspond to a lateral tangent of the display screen, parallel to the direction of extension of the wristband, the y-axis pointing in the positive direction towards the watch display screen.

That is, in this example, the origin of the watch coordinate system may be located at the upper left of the display screen, and both axial directions of the watch coordinate system may circumscribe the display screen, respectively.

It should be noted that the unit length of each axis in the watch coordinate system may be related to the resolution of the watch display screen.

For example, the resolution of the watch display is 454 x 454 and the diameter is Dw. Then, in the watch coordinate system, the unit length in the x-axis and the y-axis can be Dw/454.

For ease of illustration, in the examples of the present application, 1 is normalized to the unit length in the x-axis direction and 1 is normalized to the unit length in the y-axis direction. Then, when the resolution of the watch display is 454×454, the diameter Dw of the watch display may be 454.

It should be noted that the construction of the watch coordinate system shown in fig. 12 is only one example. In other embodiments, the particular positional relationship of the watch coordinate system to the watch display may also differ from fig. 12. After the watch coordinate system is constructed, the relative position relation with the watch display screen can be fixed and does not change any more.

Under the watch coordinate system, the rotation region parameters corresponding to the hands can be identified.

It will be appreciated that each pointer may correspond to a rotation region at different times.

Taking the same pointer length at different times as an example. Then, during a 360 degree rotation on the dial, one pointer may correspond to one rotation area. The rotation region may include a circle having a radius of a length from a rotation center to an end of the pointer.

In the application, the rotation area of the pointer can be specifically an area corresponding to a circular circumscribed rectangle swept by the pointer in 360 degrees. In some embodiments, the circumscribed rectangle may be a square with equal sides.

By way of example, the rotation region parameters of the pointer may include: the rotation area corresponds to the coordinates of one vertex of the rectangle in the watch coordinate system. For example, the vertex may be the vertex closest to the origin of the watch coordinate system. In connection with the example of fig. 12, the vertex may be the vertex of the rotation region corresponding to the upper left corner of the rectangle.

The rotation region parameters may also include: the rotation region corresponds to the x-axis width and the y-axis width of the rectangle. It will be appreciated that when the rotation region corresponds to a square, then the x-axis width and the y-axis width are the same.

Taking the hour hand as an example.

Referring to fig. 13, the rotation region parameters corresponding to the hour hand may include: the rotation region of the hour hand corresponds to the vertex coordinates (x 1, y 1) of the upper left corner of the rectangle, the rotation region of the hour hand corresponds to the x-axis width a1 of the rectangle, and the rotation region of the hour hand corresponds to the y-axis width b1 of the rectangle. In some implementations, a1 may be equal to b1.

Similarly, the rotation region parameters of the minute hand may include: the rotation region of the minute hand corresponds to the vertex coordinates (x 2, y 2) of the upper left corner of the rectangle, the rotation region of the minute hand corresponds to the x-axis width a2 of the rectangle, and the rotation region of the minute hand corresponds to the y-axis width b2 of the rectangle. In some implementations, a2 may be equal to b2.

The rotation region parameters of the second hand may include: the rotation area of the second hand corresponds to the vertex coordinates (x 3, y 3) of the upper left corner of the rectangle, the rotation area of the second hand corresponds to the x-axis width a3 of the rectangle, and the rotation area of the second hand corresponds to the y-axis width b3 of the rectangle. In some implementations, a3 may be equal to b3.

The dial management application can acquire the rotation area parameters corresponding to the hour hand, minute hand and second hand through analysis processing of the data file D.

In some embodiments, the rotation region parameter may be identified by an array identified as rotate_rect.

For example, by the analysis processing of the data file D, the dial management application can acquire the rotation area parameter of the hour hand as rotation_rect= "x1, y1, a1, b1". As a specific example, the rotation region reference of the hour hand may be specifically: rotate_rect= "88,88,279,279".

Similarly, by the parsing process of the data file D, the dial management application can acquire the rotation area parameter of the minute hand as rotation_rect= "x2, y2, a2, b2". As a specific example, the rotation area reference of the minute hand may be specifically: rotate_rect= "24,24,405,405".

By the analysis processing of the data file D, the dial management application can acquire the rotation area parameter of the second hand as rotation_rect= "x3, y3, a3, b3". As a specific example, the rotation area reference of the second hand may be specifically: rotate_rect= "4,4,446,446".

As shown in fig. 10, the dial management application may also acquire the coordinates of the rotation center of each pointer in the respective corresponding image coordinate system through the analysis processing of the data file D.

The image coordinates are first exemplified below.

The description of 1002 in fig. 10 is incorporated. Each pointer may correspond to a rectangular image. In this example, the image coordinate system may be established from the corresponding rectangular image. For example, the origin of the image coordinate system may be set at the upper left corner of the rectangular image to which the pointer corresponds. The two axial directions of the image coordinate system are along the long side and the short side of the rectangular image respectively.

As an example, an image coordinate system will be described with reference to fig. 14 by way of example.

As shown in FIG. 14, the image coordinate system of the hour hand may be the u1-v1 coordinate system. The origin of the u1-v1 coordinate system may correspond to the upper left corner of the rectangular image of the hour hand, the axis direction of u1 may be along the short side of the rectangular image of the hour hand, and the axis direction of v1 may be along the long side of the rectangular image of the hour hand.

In the u1-v1 coordinate system, the coordinates of the rotation center 1 of the hour hand may be (xr 1, yr 1).

It should be noted that the calibration of the unit length in the watch coordinate system is similar to that described above. In the present application, the unit length of each axis direction in the image coordinate system may also correspond to the resolution of the watch display screen. In some embodiments, the unit length of each axial direction in the image coordinate system may be the same as the unit length of the axial direction in the corresponding direction in the watch coordinate system.

Thus, by analyzing the data file D, the dial management application can acquire the coordinates of the rotation center of the hour hand in the image coordinate system of the hour hand as (xr 1, yr 1).

Similar to the hour hand, in the present application, the image coordinate system of the minute hand may be the u2-v2 coordinate system. The origin of the u2-v2 coordinate system may correspond to the upper left corner of the rectangular image of the minute hand, the axis direction of u2 may be along the short side of the rectangular image of the minute hand, and the axis direction of v2 may be along the long side of the rectangular image of the minute hand. In the u2-v2 coordinate system, the coordinates of the rotation center 2 of the minute hand may be (xr 2, yr 2). Thus, by analyzing the data file D, the dial management application can acquire the coordinates of the rotation center of the minute hand in the image coordinate system of the minute hand as (xr 2, yr 2).

The image coordinate system of the hour hand may be a u3-v3 coordinate system. The origin of the u3-v3 coordinate system may correspond to the upper left corner of the rectangular image of the second hand, the axis direction of u3 may be along the short side of the rectangular image of the second hand, and the axis direction of v3 may be along the long side of the rectangular image of the second hand. In the u3-v3 coordinate system, the coordinates of the rotation center 3 of the second hand may be (xr 3, yr 3). By this, by analyzing the data file D, the dial management application can acquire the coordinates (xr 3, yr 3) of the rotation center of the second hand in the image coordinate system of the second hand.

In some embodiments, the coordinates of the center of rotation of the pointer under the respective corresponding image coordinate system may be identified as rotate_point_hand.

Then, the coordinates of the rotation center of the hour hand under the image coordinate system of the hour hand can be identified as: rotate_point_hand= (xr 1, yr 1). As a specific example, xr1 may be 17 and yr1 may be 139. I.e., the corresponding rotate_point_hand= (17, 139).

Similarly, the coordinates of the center of rotation of the minute hand under the image coordinate system of the minute hand can be identified as: rotate_point_hand= (xr 2, yr 2). As a specific example, xr2 may be 16 and yr2 may be 203. That is, the corresponding rotation_point_hand= (16,203) is sorted.

The coordinates of the rotation center of the second hand in the image coordinate system of the second hand can be identified as: rotate_point_hand= (xr 3, yr 3). As a specific example, xr3 may be 19 and yr3 may be 223. That is, the rotation_point_hand= (19,223) corresponding to the second hand.

Thus, through the above description about fig. 12 to 14, the dial management application can obtain the rotation area parameters in the watch coordinate system corresponding to each pointer and the coordinates of the rotation center in the corresponding image coordinate system from the data file D corresponding to the dial 2.

For example, the respective parameters corresponding to the hour hand may include:

Draw_type＝"hand_res"，value_type＝"150"，rotate_point_hand＝(xr1，yr1)，rotate_rect＝"x1,y1,a1,b1"。

the various parameters corresponding to the minute hand can comprise:

Draw_type＝"hand_res"，value_type＝"153"，rotate_point_hand＝(xr2，yr2)，rotate_rect＝"x2,y2,a2,b2"。

the respective parameters corresponding to the hour hand can include:

Draw_type＝"hand_res"，value_type＝"154"，rotate_point_hand＝(xr3，yr3)，rotate_rect＝"x3,y3,a3,b3"。

thus, from the above description of fig. 11-14, those skilled in the art should be able to understand in detail the parsing process of the data file D for disk application management.

In the embodiment of the present application, the dial management application may also calculate and acquire the coordinates of the rotation center of each pointer in the watch coordinate system according to each parameter as shown in 1003 in fig. 10.

By this processing, the dial management application can unify the rotation centers of the hour hand, minute hand, and second hand to the same coordinate system.

For example, referring to fig. 15, the dial management application may obtain the coordinates of the center of rotation of the hour hand in the watch coordinate system based on the rotation area parameters of the hour hand in the watch coordinate system and the coordinates of the center of rotation of the hour hand in the hour hand image coordinate system.

Similarly, the dial management application may obtain the coordinates of the rotation center of the minute hand in the watch coordinate system based on the rotation area parameter of the minute hand in the watch coordinate system and the coordinates of the rotation center of the minute hand in the minute hand image coordinate system.

The dial management application may acquire the coordinates of the rotation center of the second hand in the watch coordinate system from the rotation area parameter of the second hand in the watch coordinate system and the coordinates of the rotation center of the second hand in the second hand image coordinate system.

As one possible implementation, the dial management application may calculate the coordinates of the rotation center of the acquisition pointer in the watch coordinate system according to the following formula (1) and formula (2), respectively.

Formula (1):

Xw＝rotate_rect.x+(rotate_rect.a)/2-rotate_point_hand.xr+rotate_point_hand.xr；

formula (2):

Yw＝rotate_rect.y+(rotate_rect.b)/2-rotate_point_hand.yr+rotate_point_hand.yr。

where (Xw, yw) is the coordinates of the center of rotation of the pointer in the watch coordinate system. The rotation_rect. X is the x coordinate of the upper left corner of the rectangle corresponding to the rotation region of the pointer in the watch coordinate system.

The rotation_rect.y is the y coordinate of the upper left corner of the rectangle corresponding to the rotation region of the pointer in the watch coordinate system.

The rotation_rect.a is the x-axis width of the rotation region of the pointer corresponding to the rectangle in the watch coordinate system. The rotation_rect.b is the y-axis width of the rotation region of the pointer corresponding to the rectangle in the watch coordinate system.

The rotation_point_hand. The rotation_point_hand.

Taking the hour hand as an example, the coordinates of the rotation center of the hour hand in the watch coordinate system can be denoted as (Xw 1, yw 1).

In combination with the specific example of the foregoing examples, for the hour hand, rotation_rect= "88,88,279,279", rotation_point_hand= "17, 139".

Then xw1=88+279/2-17+17=227 according to formula (1).

Yw1=88+279/2-139+139=227 according to formula (2).

That is, in this example, the coordinates of the rotation center 1 of the hour hand in the watch coordinate system are: (227).

It should be noted that, in the embodiment of the present application, "/" corresponds to a calculation operation of dividing by and rounding. For example, in the example of the calculation of the hour hand above, 279 divided by 2 equals 139.5. Then the result of 279/2 may be 139 the result of removing the decimal point by the corresponding divide-by-round calculation operation. Thus, xw1=88+139=227. Other similar items will not be described in detail.

Similarly, the coordinates of the rotation centers of the minute hand and the second hand in the watch coordinate system in the above example can be calculated and acquired.

For example, for minute hand, rotate_rect= "24,24,405,405", rotate_point_hand= "16,203". Then, according to the formula (1) and the formula (2), the coordinates of the rotation center 2 of the minute hand in the watch coordinate system may be (226 ).

For the second hand, rotation_rect= "4,4,446,446", rotation_point_hand= "19,223". Then, according to the formula (1) and the formula (2), the coordinates of the rotation center 3 of the determined second hand in the watch coordinate system may be (227 ).

In this way, the dial management application can acquire the background image of dial 2, the picture resources of dial 2, and the configuration file of dial 2 as shown in fig. 10.

In this configuration file of the dial 2, an identifier of each pointer, as shown at 1003 in fig. 10, a rotation area parameter of each pointer in the watch coordinate system, and coordinates of the rotation center of each pointer in the hour hand image coordinate system may be included.

In some embodiments, the configuration file of the dial 2 may further include the coordinates of the rotation center of each pointer in the watch coordinate system obtained by calculation as in the formula (1) and the formula (2).

The module in the frame layer of the watch can render the dial 2 according to the data acquired by the dial management application, thereby acquiring a corresponding dial rendering result. Thus, after the dial 2 is rendered, the display screen of the watch can display according to the dial rendering result. Thereby realizing the switching display from dial 1 to dial 2.

For example, refer to fig. 16. The dial management may send the display element information acquired by the parsing process to the UI tool in the framework layer or the touchGFX framework.

The display element information may include a background image of the dial 2, a picture resource of the dial 2, and a configuration file of the dial 2, among others.

It should be noted that, in some implementations, the dial management application may send the data of the display element information directly to the frame layer for rendering. In other implementations, the data of the display element information may also be stored in a corresponding area of the flash memory of the watch. For example, the data of the display element information may be stored in a storage area configured corresponding to the f_id. In this way, the dial management application can transmit the storage address corresponding to the display element information to the frame layer to realize data transmission.

The UI tool or touchGFX framework in the framework layer can conduct rendering processing according to the display element information, so that a dial rendering result is obtained. The dial rendering result can correspond to all data displayed based on the dial 2 at the current time.

As shown in fig. 16, the UI tool or touchGFX framework may store the dial rendering results in a dial display buffer in flash memory. The dial display buffer may be a storage space for storing display data. In this way, the display screen of the watch can read the dial rendering result corresponding to the dial 2 from the dial display buffer to display, thereby realizing the switching display from the dial 1 to the dial 2.

In the above process, the UI tool or touchGFX frame in the frame layer may perform verification on the coordinates of the rotation center of each pointer carried in the configuration file of the dial 2 in the watch coordinate system according to a preset policy during the rendering process of each pointer.

For two or more pointers that should have the same center of rotation, the UI tool or touchGFX framework may perform normal rendering of the respective pointers if it is determined that the coordinates of the centers of rotation of the pointers in the watch coordinate system are all the same.

Correspondingly, the UI tool or touchGFX framework may discard one or more pointers in case it is determined that the coordinates of the rotation centers of the pointers in the watch coordinate system are not identical, thereby avoiding erroneous rendering results.

Wherein the UI tool or touchGFX framework can determine that two or more pointers should have the same center of rotation from the identifiers of the respective pointers carried in the configuration file of dial 2.

For example, the UI tool or touchGFX framework may determine that the object is a pointer based on the type identifier of each pointer.

For example, the UI tool or touchGFX framework may determine that the corresponding object is a pointer in the case where draw_type is hand_res.

For these pointers, the UI tool or touchGFX framework may determine two or more pointers that should have the same center of rotation from the corresponding distinguishing identifier.

In some embodiments, the UI tool or touchGFX framework may be preconfigured with a first correspondence. The first correspondence may include at least one entry therein. Each of the at least one entry may include at least two distinguishing identifiers. The at least two distinguishing identifiers located in the same entry may correspond to two or more objects having the same center of rotation.

In various embodiments, the implementation of pre-configuring the first correspondence may include: the watch is stored in advance. Alternatively, the watch is obtained from a cell phone. For example, when the wristwatch receives the data file D from the mobile phone, the wristwatch acquires the first correspondence relationship from the mobile phone.

As an example, table 1 below provides an example of a first correspondence.

TABLE 1

ID	Distinguishing identifier
		#1	150,153，154
#2	114,163
		……	……

As shown in table 1, three objects with distinguishing identifiers 150,153 and 154 may have the same center of rotation. The two objects with distinguishing identifiers 114 and 163 may have the same center of rotation. And so on.

In this way, the UI tool or touchGFX framework can determine two or more objects that should have the same center of rotation according to the first correspondence.

For example, the UI tool or touchGFX framework may prestore pointers with value_type 150,153 and 154 and may have the same rotation center. Then, by looking up the distinguishing identifier of each pointer, the UI tool or touchgo fx framework can recognize that the corresponding pointers of the hour, minute and second hands should have the same center of rotation.

In combination with the foregoing description about the formula (1) and the formula (2), the rotation center coordinates obtained by calculation using the rotation area parameters of the respective hands carried in the configuration file of the dial 2 in the watch coordinate system are not exactly the same.

For example, the coordinate of the rotation center 1 of the hour hand in the watch coordinate system may be (227), the coordinate of the rotation center 2 of the minute hand in the watch coordinate system may be (226 ), and the coordinate of the rotation center 3 of the second hand in the watch coordinate system may be (227 ).

Thus, as illustrated in fig. 16, the UI tool or touchGFX framework may discard one or more pointers in case it is determined that the coordinates of the rotation centers of the hour hand, minute hand, and second hand in the watch coordinate system are not exactly the same, thereby avoiding erroneous rendering results. This results in a display result shown as 503 in fig. 5.

It can be understood that the dial designer cannot know the accurate calibration of the watch coordinate system, so the rotation area parameters of the pointer in the file data D corresponding to the dial 2 acquired by the mobile phone from the cloud server under the watch coordinate system may not be accurate. This results in inaccurate results of calculating the rotation center of the acquired pointer in the watch coordinate system based on the rotation area parameters of the acquired pointer in the watch coordinate system in the file data D. Resulting in inconsistent coordinates of the centers of rotation of the hour hand, minute hand, and second hand, which should be the same.

In the embodiment of the present application, as shown in fig. 17, when the dial management application calculates the coordinates of the rotation center of each pointer in the watch coordinate system, the rotation area parameters corresponding to each pointer may be updated in combination with the resolution of the current dial. The rotation center under the watch coordinate system obtained by calculation according to the updated rotation area parameters can be more accurate, and the coincidence of the rotation centers of each hour hand, each minute hand and each second hand is ensured. And further, the rotation center coordinates of the pointers indicated by the data sent to the UI tool or the touchGFX frame for rendering by the dial management application are overlapped, so that any pointer is not discarded when the UI tool or the touchGFX frame renders the dial 2, and the effect shown as 502 in fig. 5 is obtained.

Illustratively, in this example, after acquiring the configuration file as shown in 1003 of fig. 10, the dial management application may update the corresponding rotation area parameter for each pointer according to the following formulas (3) to (6).

Equation (3): rotate_rect.a' =rotate_point_hand.

Equation (4): rotate_rect.b '=rotate_rect.a';

equation (5): rotate_rect.x '= (resolution of watch-rotate_rect.b')/2;

equation (6): rotate_rect.y '=rotate_rect.x'.

The rotation_rect.a' is the x-axis width of the rectangle corresponding to the updated rotation region of the pointer. The rotation_rect.b' is the y-axis width of the rectangle corresponding to the updated rotation region of the pointer. (x ', y') is the vertex coordinates of the upper left corner of the corresponding rectangle of the rotation region of the pointer after updating. rotation_point_hand.y is the v-coordinate of the center of rotation of the pointer in the image coordinate system.

In the present application, dial management is applied after updating the rotation area parameters of the hands of each hand in the watch coordinate system according to the above formulas (3) to (6), the coordinates of the rotation center of each hand in the watch coordinate system can be calculated from the updated parameters and the coordinates of the rotation center of the hand in the hand image coordinate system.

Illustratively, continuing with the specific implementation provided in the previous example, the updating of the rotation area parameters of the respective hands in the watch coordinate system in this example, and the corresponding calculation of the coordinates of the rotation center of the respective hands in the watch coordinate system, are illustrated. The resolution of the watch display screen is 454 x 454.

For example, for the hour hand, the acquired rotation_rect= "88,88,279,279", rotation_point_hand= (17, 139) is parsed from the data file D. That is, for the hour hand, rotate_point_hand. Yr is 139.

Then, according to the formulas (3) to (6), the updated rotation_rect= "88,88,278,278" of the hour hand. Based on this, the above-described formula (1) and formula (2) are combined, and the calculated coordinate of the rotation center of the hour hand in the watch coordinate system is (227) based on the updated rotation_rect of the hour hand.

As another example, for minute hand, the acquired rotation_rect= "24,24,405,405", rotation_point_hand= (16,203) is parsed from the data file D. That is, for the minute hand, rotate_point_hand. Yr is 203.

Then, according to the formulas (3) to (6), the updated rotation_rect= "24,24,406,406" of the minute hand. Based on this, in combination with the above-described formula (1) and formula (2), the calculated coordinate of the rotation center of the minute hand in the watch coordinate system is (227) based on the updated rotation_rect of the minute hand.

As another example, for the second hand, the acquired rotation_rect= "4,4,446,446", rotation_point_hand= (19,223) is parsed from the data file D. That is, for the second hand, the rotation_point_hand. Yr is 223.

Then, according to the formulas (3) to (6), the updated rotation_rect= "4,4,446,446" of the second hand. Based on this, the above-described formula (1) and formula (2) are combined, and the coordinate of the rotation center of the second hand calculated from the updated rotation_rect of the second hand in the watch coordinate system is (227).

It can be seen that after updating the rotation area in the watch coordinate system of each hand according to the parameters of the image coordinate system, the coordinates of the rotation centers of the acquired hour hand, minute hand and second hand in the watch coordinate system are (227), that is, the three are overlapped. Thus, the watch dial management application, after sending the respective display element information to the frame layer, the UI tool or touchGFX frame in the frame layer can check to determine that the centers of rotation of the hour hand, minute hand, and second hand coincide. And then, carrying out complete rendering on the three pointers, and storing dial rendering results comprising the complete rendering results in a dial display buffer. Thus, the display screen can obtain the correct effect as shown in 502 of fig. 5 when displaying the dial rendering result stored in the table display buffer.

In order to enable those skilled in the art to more clearly understand the implementation of the scheme provided by the embodiment of the present application, the following describes in detail the processing flow of the watch after receiving the data file D of the dial 2 in conjunction with the flowchart provided in fig. 18.

By way of example, the scheme provided in fig. 18 may be used to support a wristwatch to implement S808 as shown in fig. 8.

As shown in fig. 18, the scheme may include:

s1801, analyzing the dial management data file 2, and obtaining a background image, a picture resource, and a configuration file of the dial 2.

The data file 2 may be, for example, a data file corresponding to the dial 2 acquired by the wristwatch.

As an example, in connection with fig. 2-3, and fig. 7-8, the data file 2 may in this example be a wristwatch implemented based on the scheme shown in fig. 7 and 8, obtained from a control device (e.g. a mobile phone) of the user.

As shown in fig. 18, in some embodiments, the execution of S1801 may be triggered after receiving the dial application indication. The dial application indication may carry a file transmission unique identifier (f_id) corresponding to the dial 2, so that the watch determines that the processing of the S1801 needs to be triggered for the data file 2 corresponding to the dial 2.

In this example, specific implementations of the background image, the picture resource, and the configuration file of the dial 2 may be referred to as the description of fig. 10 to 14. For example, the background image may include background data that is common at any time corresponding to the dial 2. The picture resources may include images of the hour hand, minute hand, and second hand in the dial 2, respectively. The configuration file may include an identifier corresponding to each pointer, a rotation area parameter under the watch coordinate system, and coordinates of the rotation center of each pointer under the respective corresponding image coordinate system.

S1802, dial management determines that the dial 2 includes a first pointer and a second pointer having the same rotation center according to the configuration file.

For example, the dial management may determine from the configuration file that at least two pointers having the same rotation center are included in the dial 2. For example, the at least two pointers having the same center of rotation include a first pointer and a second pointer.

It will be appreciated that the first and second hands may be any two of an hour hand, a minute hand, and a second hand, corresponding to the foregoing examples. The following implementation of the first pointer and the second pointer can be applied to other pointers having the same rotation center as the first pointer and the second pointer. For example, the at least two pointers further include a third pointer having the same center of rotation as the first pointer and the second pointer. Then, the processing mechanism of the third pointer may refer to the processing mechanism for the first pointer or the second pointer in the following. The details are not described in detail.

It should be noted that, in this example, dial management may determine that at least two pointers are included in dial 2 according to the aforementioned implementation of the verification process of UI tool or touchGFX framework, and that the first pointer and the second pointer exist in the at least two pointers to have the same rotation center.

As an example, dial management may determine that dial 2 includes at least two pointers based on a type identifier in a configuration file.

For example, dial management may determine that there are at least two objects of draw_type as hand_res among all the objects of the data file 2. Then at least two objects for which the draw_type is hand_res may correspond to pointers. In this example, the at least two objects of the draw_type being hand_res may include a first pointer and a second pointer.

The dial management may also determine, from the distinguishing identifier in the configuration file, at least two pointers having the same rotation center among the at least two pointers included in the dial 2.

For example, dial management may determine two or more pointers having the same rotation center from a first correspondence stored in advance. The description of the first correspondence may refer to the foregoing examples in table 1, and will not be repeated here.

In this example, the dial management may determine that the first pointer and the second pointer have the same rotation center according to the first correspondence relationship.

S1803, dial management updates the rotation area parameters corresponding to the first pointer and the second pointer.

For example, the dial management may update the rotation area parameter of the first pointer in the watch coordinate system according to the coordinates of the rotation center of the first pointer in the pointer image coordinate system and the resolution of the watch.

Similarly, dial management may update the rotation area parameter of the second pointer in the watch coordinate system based on the coordinates of the rotation center of the second pointer in the pointer image coordinate system and the resolution of the watch.

For specific implementation, reference may be made to fig. 17 and the descriptions of the foregoing formulas (1) to (6), which are not repeated here.

In this way, the dial management can update the updated rotation area parameters of the first pointer and the second pointer into the corresponding configuration files.

S1804, dial management determines coordinates of rotation centers of the first pointer and the second pointer in the watch coordinate system according to the updated rotation region parameters of the first pointer and the second pointer.

In connection with the description of fig. 17, the coordinates of the respective rotation centers determined according to the updated rotation region parameters of the first pointer and the second pointer may be the same.

S1805, dial management sends display element information to the image rendering module.

The display element information may include, for example, a background image of dial 2, a picture resource, and a profile.

In the configuration file, an identifier of the first pointer may be included, the center of rotation of the first pointer being at a coordinate of the image coordinate system of the first pointer. The configuration file may also include the updated rotation area parameters of the first pointer in the watch coordinate system.

In some embodiments, the configuration file may further include coordinates of the center of rotation of the first pointer in a watch coordinate system.

The relevant parameters of the second pointer may also be included in the configuration file.

For example, in the configuration file, an identifier of the second pointer may be included, the center of rotation of the second pointer being at a coordinate of the second pointer in the image coordinate system. The configuration file may also include the updated rotation area parameters of the second hand in the watch coordinate system.

In some embodiments, the configuration file may further include coordinates of the center of rotation of the second pointer in the watch coordinate system.

It will be appreciated that in case more pointers are included in dial 2, the configuration file may also include configuration parameters of other pointers.

S1806, the image rendering module determines that the first pointer and the second pointer have the same rotation center according to the configuration file in the display element information.

The image rendering module may be, for example, a module in a wristwatch having image rendering processing capabilities. For example, the image rendering module may correspond to the UI tool or touchGFX framework in the foregoing examples.

S1807, the image rendering module determines that the rotation center coordinates of the first pointer and the second pointer are the same according to the coordinates of the rotation centers of the first pointer and the second pointer in the display element information under the watch coordinate system.

In this example, the execution of S1806 to S1807 may refer to fig. 17, and the corresponding execution implementation of dial management shown in S1802 described above, and will not be described herein.

S1808, the image rendering module renders the dial 2 according to the display element information, and a corresponding dial rendering result is obtained.

It will be appreciated from the foregoing that the centre of rotation of the updated first and second hands has the same coordinates in the watch coordinate system. Accordingly, in this S1808, the image rendering module may perform complete rendering of the first pointer and the second pointer without discarding any pointer.

S1809, the image rendering module sends dial rendering results to the memory. The dial rendering result may be a rendering result corresponding to dial 2.

S1810, the memory stores the dial rendering result.

S1811, the display screen acquires the dial rendering result from the memory.

S1812, the display screen displays the dial 2 according to the dial rendering result.

Thus, by this example of the scheme shown in fig. 18, the wristwatch can realize the identification of the hands in the dial and the parameter update, thereby ensuring that the centers of rotation of the hour hand, minute hand and second hand have the same coordinates in the watch coordinate system. And the watch can completely render each pointer, so that the problem of pointer loss in display according to the dial rendering result is avoided.

In the above examples, each pointer is used for time display. It will be appreciated that in other scenarios, the first and second pointers may also be pointers with the same center of rotation on the dial for other information presentation. The scheme provided by the embodiment of the application can also be applied to the scene so as to obtain the complete pointer display effect.

Furthermore, in other embodiments, the steps and associated names in the above examples may also be different.

For example, an electronic device such as a wristwatch to which a dial is applied may be referred to as a first electronic device, and an electronic device such as a mobile phone as a control device may be referred to as a second electronic device. The interface corresponding to the dial 2 to be displayed in a switching manner may be referred to as a first display interface. The data file D corresponding to the dial 2 may be referred to as a first data file. The hands having the same rotation center in the dial 2 may include a first hand, a second hand, and the like. For example, the first hand may correspond to an hour hand, the second hand may correspond to a minute hand, a second hand, or the like. Before updating, the rotation area parameter corresponding to the first pointer transmitted to the watch by the mobile phone may be a third rotation area parameter. The rotation area parameter of the first pointer determined by the wristwatch according to the resolution and the rotation center of the first pointer in the image coordinate system may be referred to as a first rotation area parameter. Similarly, before updating, the rotation area parameter corresponding to the second pointer transmitted to the watch by the mobile phone may be a fourth rotation area parameter. The rotation area parameter of the second pointer determined by the wristwatch according to the resolution and the rotation center of the second pointer in the image coordinate system may be referred to as a second rotation area parameter.

Further, the picture resources of the first pointer may include a first image and the picture resources of the second pointer may include a second image.

The image coordinate system of the first image is a first coordinate system, and the coordinates of the rotation center of the first pointer in the first coordinate system are first coordinates.

The image coordinate system of the second image is a second coordinate system, and the coordinates of the rotation center of the second pointer in the second coordinate system are second coordinates. The watch coordinate system established according to the watch display screen may be a third coordinate system.

Further, the type identifiers of the first pointer and the second pointer may each be a first type identifier. For example, the first type identifier may be hand_res. The distinguishing identifier of the first pointer may be a first distinguishing identifier and the distinguishing identifier of the second pointer may be a second distinguishing identifier.
