Detailed Description
The core of the invention is to provide a watch control method, a display terminal and a watch, which not only can realize screen projection of the watch, but also can realize reverse control of the watch, and improve user experience.
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 2a and fig. 2b, wherein fig. 1 is a process flow chart of a watch control method according to the present invention, fig. 2a is a schematic diagram of a display screen of a watch according to the present invention being displayed on a display terminal, and fig. 2b is a schematic diagram of a display screen of another watch according to the present invention being displayed on a display terminal.
The method is applied to the display terminal and comprises the following steps:
s11: establishing communication connection with the watch through a terminal communication module;
s12: determining a mapping relation between a display coordinate system of the display terminal and a watch display coordinate system of the watch on the display terminal;
s13: determining a picture to be displayed based on a display picture sent by the watch, and displaying the picture to be displayed on a display screen of the display terminal according to the mapping relation;
s14: and determining the coordinates of the user operation action in the watch display coordinate system based on the mapping relation, and sending the determined coordinates to the watch so that the watch responds correspondingly based on the coordinates.
In order to implement data interaction with the watch, the display terminal first establishes a communication connection with the watch through a terminal communication module, where the terminal communication module may be a WiFi hotspot, a bluetooth, and the like, and the application is not particularly limited herein. Specifically, in practical applications, the display terminal may establish a communication connection with the watch through the terminal communication module after receiving a user instruction.
In addition, considering that the size of the display screen of the watch is usually larger than that of the display screen of the display terminal, and the display terminal and the watch both have their own display coordinate systems, in order to display the display screen of the watch on the display screen of the display terminal and subsequently control the watch through the display terminal, it is further necessary to map the watch display coordinate system of the watch onto the display screen of the display terminal, and determine the mapping relationship between the display coordinate system of the display terminal and the watch display coordinate system of the watch on the display terminal. It should be noted that, the display coordinate system of the watch on the display terminal and the display coordinate system of the watch on the display screen of the watch are a coordinate system, that is, when the watch receives the coordinates of the display coordinate system of the watch on the display terminal sent by the display terminal, the coordinates are directly obtained by the display coordinate system of the watch on the display screen of the watch, and the corresponding response can be directly performed based on the coordinates.
After the communication connection with the watch is established, the watch can directly send a display picture to the display terminal, or send a screen projection control request instruction to the display terminal first, and send the display picture to the display terminal after the display terminal agrees. After receiving the display picture sent by the watch, the display terminal determines a picture to be displayed based on the display picture, and then displays the picture to be displayed on a display screen of the display terminal according to the mapping relation. The user can see the display of the watch on the display terminal. If a user wants to operate the watch, for example, select an icon in the watch, the user can select operation from a picture of the watch displayed on the display terminal, the display terminal can acquire coordinates in a display coordinate system of the display terminal where the user operates, then the coordinates of the user operation in the watch display coordinate system are determined based on the mapping relation, namely, the coordinates are converted to the watch in the same proportion, and the determined coordinates are sent to the watch, so that the watch can respond correspondingly based on the coordinates.
Therefore, by the watch control mode, not only can the screen projection of the watch be realized, but also the reverse control of the watch can be realized, and the user experience is improved.
On the basis of the above-described embodiment:
as a preferred embodiment, establishing a communication connection with a watch through a terminal communication module includes:
and the control terminal communication module generates a WiFi hotspot and establishes communication connection with the watch through the WiFi hotspot.
Referring to fig. 3, fig. 3 is a schematic diagram illustrating a connection between a display terminal and a watch according to the present invention.
In this embodiment, in order to establish a communication connection with the watch, the terminal communication module may be controlled to generate a WiFi hotspot, the watch opens the wireless local area network, the WiFi hotspot is seen in the network, and then the WiFi hotspot is clicked to establish a communication connection with the display terminal, or a password may be input after the WiFi hotspot is clicked, and when the password is correct, a communication connection is established with the display terminal. In addition, if the communication connection is established between the display terminal and the watch before, the display terminal can automatically establish the communication connection with the watch after the display terminal generates the WiFi hotspot.
In this embodiment, the display terminal and the watch establish communication connection through the WiFi hotspot, and the display terminal is suitable for big data transmission, and has a fast transmission speed and a large transmission data volume.
Of course, the display terminal and the watch may be connected in other manners, such as bluetooth, etc., and the application is not limited thereto.
As a preferred embodiment, determining a mapping relationship between a display coordinate system of a display terminal and a watch display coordinate system of a watch on the display terminal includes:
determining the coordinate of the coordinate origin of the watch display coordinate system in the display coordinate system of the display terminal based on the preset position of the coordinate origin of the watch display coordinate system on the display screen of the display terminal and the display coordinate system of the display terminal;
taking a preset proportion as a scaling proportion of a watch display coordinate system in a display coordinate system of a display terminal, wherein the preset proportion is a proportion of the watch display coordinate system and an original watch display coordinate system in the watch, and the preset proportion is 1: 1;
and determining the mapping relation between the display coordinate system of the display terminal and the display coordinate system of the watch based on the coordinates and the scaling.
After the display terminal is in communication connection with the watch, if a display frame of the watch is to be displayed on the display terminal, a mapping relationship between a display coordinate system of the display terminal and a watch display coordinate system of the watch on the display terminal needs to be established. Specifically, determining the position of the watch coordinate system in the display coordinate system of the display terminal requires knowing two points, one being the coordinates of the origin of coordinates of the watch coordinate system in the display coordinate system of the display terminal and the other being the scale of the watch coordinate system.
Firstly, the coordinates of the coordinate origin of the watch display coordinate system in the display coordinate system of the display terminal can be determined based on the preset position of the coordinate origin of the watch display coordinate system on the display screen of the display terminal and the display coordinate system of the display terminal. Secondly, the preset proportion can be used as the scaling of the display coordinate system of the watch in the display coordinate system of the display terminal, wherein the preset proportion is the proportion of the display coordinate system of the watch and the display coordinate system of the original watch in the watch, and the preset proportion is preferably 1:1, namely the original proportion display of the display picture of the watch is realized. The preset position and the preset ratio may be preset and stored in the display terminal, or may be sent by the watch terminal, and the application is not particularly limited herein. And then determining the mapping relation between the display coordinate system of the display terminal and the display coordinate system of the watch based on the coordinates and the scaling.
Therefore, the display frame of the watch is displayed on the display screen of the display terminal and the watch is subsequently controlled by the display terminal by establishing the mapping relation between the display coordinate system of the display terminal and the watch display coordinate system of the watch on the display terminal. And after determining the coordinates of the user operation actions in the watch display coordinate system based on the mapping relation, the watch can directly respond correspondingly based on the coordinates.
As a preferred embodiment, after determining the mapping relationship between the display coordinate system of the display terminal and the watch display coordinate system of the watch on the display terminal, the method further includes:
receiving an adjusting instruction of a watch display coordinate system sent by a user;
adjusting a watch display coordinate system based on the adjustment instruction;
the adjusting instruction comprises the adjustment of a coordinate origin of a watch display coordinate system and/or the adjustment of a scaling;
and updating the mapping relation between the display coordinate system of the display terminal and the display coordinate system of the watch based on the adjustment of the coordinate origin and/or the adjustment of the scaling.
In particular, considering that the display screen of the watch is relatively small, the watch display coordinate system can be adjusted for the convenience of the user, wherein the adjustment comprises the adjustment of the coordinate origin of the watch display coordinate system and/or the adjustment of the scaling. When only the origin of coordinates of the watch display coordinate system is adjusted, the position of the display screen of the whole watch is shifted. When only the scaling is adjusted, the other is scaled corresponding to a certain point on the display screen.
Referring to fig. 4a, fig. 4b and fig. 4c, fig. 4a is a position diagram of a display coordinate system of a display terminal and a display coordinate system of a watch provided by the present invention, fig. 4b is a position diagram of a display coordinate system of another display terminal and a display coordinate system of a watch provided by the present invention, and fig. 4c is a position diagram of a display coordinate system of another display terminal and a display coordinate system of a watch provided by the present invention, wherein the display coordinate system of the display terminal is x-o-y, the origin of coordinates is o, the abscissa is x, and the ordinate is y; the watch display coordinate system is x1-o1-y1, the coordinate origin is o1, the abscissa is x1, and the ordinate is y1, and the watch can directly carry out corresponding operations based on the coordinates (x1, y1) in the watch display coordinate system.
In fig. 4a, the origin o of the display terminal coordinate system coincides with the origin o1 of the watch display coordinate system, and at this time, the mapping relationship between the display terminal coordinate system and the watch display coordinate system of the watch on the display terminal is: x1 ═ x, y1 ═ y.
In fig. 4 a-4 b, based on fig. 4a, the coordinate origin of the display coordinate system of the watch is adjusted, and the coordinate origin moves to the right by 2 and moves to the down by 2, respectively, so that the mapping relationship between the display coordinate system of the updated display terminal and the display coordinate system of the watch is as follows: x1 ═ x-2, y1 ═ y-2.
In fig. 4 b- > fig. 4c, on the basis of fig. 4c, the scale of the table display coordinate system is adjusted to 2: 1, the mapping relationship between the updated display coordinate system of the display terminal and the display coordinate system of the watch is as follows: x1 is x/2-2, and y1 is y/2-2.
Therefore, after the display coordinate system of the watch is adjusted, the mapping relation can be correspondingly updated, and after the coordinates of the user operation actions in the display coordinate system of the watch are determined based on the new mapping relation, the watch can directly and correspondingly respond based on the coordinates.
Through the mode, the user can adjust the position and/or size of the display picture of the watch on the display screen of the display terminal according to the self requirement, the user operation is facilitated, and the user experience is further improved.
As a preferred embodiment, receiving an instruction for adjusting a display coordinate system of a watch sent by a user, includes:
acquiring gesture actions of a user on a display screen of a display terminal;
and determining an adjusting instruction of a display coordinate system of the corresponding watch based on the gesture action.
Specifically, when the coordinate system of the watch is adjusted, the adjustment can be realized through gesture actions of a user on the display screen of the display terminal, for example, two fingers simultaneously select the display picture of the watch on the display screen and move in opposite directions or opposite directions, so as to zoom the display picture of the watch, for example, one finger selects and drags the display picture of the watch, so as to move the position of the display picture of the watch.
Therefore, the position and/or size of the display picture of the watch on the display screen can be adjusted in the mode, and the user experience is further improved.
As a preferred embodiment, determining a picture to be displayed based on a display sent by a watch includes:
receiving a difference part picture which is sent by a watch and is determined after a current frame display picture acquired by the watch is compared with a previous frame display picture;
and replacing the difference part picture with the corresponding position of the previous frame of display picture to obtain the picture to be displayed.
In the prior art, when a display screen of a watch is uploaded to a display terminal, generally, a screen is captured first, and then the whole screen is sent to the display terminal, or a video stream is uploaded to the display terminal. By adopting the two modes, the data volume transmitted each time is larger, so that the delay feeling and the hysteresis feeling are increased, and the whole process is not smooth.
In order to improve the fluency of data transmission, in the application, the watch firstly obtains a current frame display picture, then compares the current frame display picture with a previous frame display picture, determines a difference part picture, and sends the difference part picture to the display terminal, and after receiving the difference part picture, the display terminal directly replaces the difference part picture with the corresponding position of the previous frame display picture to obtain a picture to be displayed.
It should be noted that the watch may, but is not limited to, capture the display image by means of screen capture.
Therefore, through the mode, the watch can compare the image data collected last time with the image data collected last time, only transmits the difference part of the two times of data to the display terminal, and other parts are not transmitted, so that the transmission rate is improved, and the overall fluency of screen projection is improved.
