Detailed Description

Exemplary embodiments of the present disclosure are described below in conjunction with the accompanying drawings, which include various details of the embodiments of the present disclosure to facilitate understanding, and should be considered as merely exemplary. Accordingly, one of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present disclosure. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.

Fig. 1 shows a scenario diagram of an embodiment of the present disclosure, as shown in fig. 1, in-vehicle host 12 in vehicle 11 and user's terminal device (e.g., mobile terminal) 13 are communicatively connected through a wireless network or a wired network. The terminal device 13 may transmit the display contents of video, pictures, etc. to the in-vehicle host 13 and display them in the in-vehicle screen 14.

In these application scenarios, the user may perform a triggering (e.g., sliding) operation on the on-vehicle screen, and the on-vehicle host performs reverse control (for short, reverse control) on the terminal device according to the triggering operation. Specifically, the vehicle-mounted host sends the reverse control data to the terminal equipment according to the triggering operation, so that the terminal equipment responds according to the reverse control data. The response includes determining display content that matches the feedback data. The display content may be displayed in an in-vehicle screen and/or a screen of the terminal device.

In one example, in order to implement the triggering operation performed by the user on the vehicle-mounted screen, so as to control the response of the terminal device, one countercontrol manner is that the vehicle-mounted host directly sends the coordinate data (x, y) of the identified triggering operation (such as sliding operation) to the terminal device, and after receiving the coordinate data, the terminal device adds a local time parameter to the coordinate data, and encapsulates the coordinate data into an event. The time parameter here is generated by the terminal device from the reception timings of the plurality of coordinate data of the trigger operation received. The terminal device determines the distance and direction of the sliding based on the locally encapsulated event and responds accordingly, for example by switching the display content based on the determined sliding distance and direction.

Taking one sliding operation as an example, the on-board host machine can divide the sliding operation into three events as a whole: a press (Action Down) event, a slide (Action Move) event, and a lift (Action Up) event.

The first event of the touch operation is an action_Down event, the vehicle-mounted host takes the coordinate of the touch operation detected for the first time as the coordinate of the action_Down event, and the action_Down event comprising the coordinate is sent to the terminal equipment. After receiving the action_down event, the terminal device takes the time point of receiving the event locally as the time (Down time) of the local pressing operation, and supplements an EventTime (the EventTime is the same value as the Down time at the moment), and packages the EventTime together into a MotionEvent.

When a user continuously slides the vehicle-mounted screen, the vehicle-mounted host continuously detects a plurality of coordinates in the sliding operation process, and generates action_move events corresponding to the coordinates respectively. And then transmitting a plurality of action_move events including the coordinates to the terminal device. For each action_move event, the terminal device may copy the Down time from the action_down event, then take the time of locally receiving the action_move event as the EventTime, and package the coordinates corresponding to the action_move event and the Down time and the EventTime into a MotionEvent.

The EventTime is not the EventTime of the actual sliding operation of the on-vehicle screen, but reaches the terminal device after a series of transmissions, and the terminal device uses the time point at the moment when the action_move event is received as the EventTime. For the terminal device, the sliding distance is processed according to the EventTime of a plurality of action_move events, if the transmission time of an action_move event is too long, the EventTime corresponding to the action_move event determined by the terminal device is distorted, so that the sliding distance is distorted, the whole touch response is not smooth, and even the phenomenon of picture jumping occurs. In addition, for a quick sliding operation performed on the on-vehicle screen, since the action_move event transmission time is long, the terminal device determines EventTime according to the time when the action_move event is received. The terminal equipment misjudges the quick interaction as slow sliding according to the Down time and EventTime in the MotionEvent, so that error response occurs to the quick sliding operation.

When the user finishes the sliding operation on the vehicle-mounted screen, the vehicle-mounted host detects coordinates (for example, coordinates when the finger lifts) at the end of the sliding operation of the user, and generates an action_up event. And the vehicle-mounted host sends the action_Up event to the terminal equipment. The terminal device copies the DownTime from the action_down event, and then takes the time of locally receiving the action_up event as EventTime. And packaging the coordinates, the Down Time and the EventTime into a MotionEvent event. Because the EventTime is the time for locally receiving the action_up event, if the data transmission time is longer, the acting time of the sliding operation determined by the terminal device according to the DownTime and the EventTime may be different from the actual acting time of the sliding operation, so that an error occurs in the response of the sliding operation of the terminal device, and the picture displayed by the vehicle-mounted screen is abnormal.

As can be seen, in the countercontrol method in the above example, the response of the terminal device to the countercontrol operation initiated from the vehicle-mounted screen has the problems of large error, unsmooth whole touch response, and even frame jumping.

The disclosure provides a reverse control method, a device and electronic equipment for vehicle-mounted display, which are applied to the fields of vehicle-mounted display, display control and the like in computer technology, so as to achieve the aim of improving the problems of larger error, unsmooth whole touch control response and even frame jumping of terminal equipment in response to reverse control operation.

Referring to fig. 2, fig. 2 is a schematic diagram of a first embodiment of the present disclosure. The reverse control method for vehicle-mounted display, provided by the embodiment, is applied to a vehicle-mounted host, the vehicle-mounted host is in communication connection with terminal equipment, and a vehicle-mounted screen of the vehicle-mounted host displays display content transmitted by the terminal equipment. As shown in fig. 2, the method includes:

s201, in response to receiving a touch operation executed on the vehicle-mounted screen, executing at least one touch position acquisition operation.

The in-vehicle screen here may be a touch screen.

The touch operation may be a click operation or a slide operation. The clicking operation may be a single-click operation, a double-click operation, or a multi-click operation.

The sliding operation herein may be a single-finger sliding operation, a two-finger sliding operation, a multi-finger sliding operation, or the like.

The execution body of the embodiment may be an in-vehicle host.

The user can execute touch operation on the vehicle-mounted screen, and the vehicle-mounted screen can sense the position of the touch operation according to the touch operation.

Various operating systems can be operated on the vehicle-mounted host, the vehicle-mounted host can interact with the vehicle-mounted screen by utilizing the operating systems, and the position of touch operation is obtained from the vehicle-mounted screen.

In some application scenarios, the vehicle-mounted host may determine the location acquisition frequency according to the duration and/or the touch speed of the touch operation of the user on the vehicle-mounted screen.

For example, for a click touch operation, the in-vehicle host may obtain the location of one or a small number of touch operations from the in-vehicle screen.

For the sliding operation, the vehicle-mounted host computer can determine the frequency of acquiring the position according to the sliding time length and the sliding speed, and then acquire the multiple touch positions according to the frequency.

For each touch operation, the touch operation may include three stages of operations, a pressing operation, a sliding operation, and a lifting operation. For the click operation, the sliding distance corresponding to the sliding operation can be considered to be zero.

After detecting that the pressing operation occurs, the execution body may acquire a position corresponding to the touch operation from the vehicle-mounted screen at least once until the lifting operation is detected.

S202, generating at least one piece of reverse control data comprising first time information and position information according to position information acquired by at least one touch position acquisition operation; the position information of the reverse control data comprises a position acquired by a primary touch position acquisition operation corresponding to the reverse control data; the first time information is used for determining duration of the touch operation in the touch position acquisition operation.

The above-mentioned position information may include coordinate information such as coordinates of a touch operation at the time of execution of the touch position acquisition operation on the on-vehicle screen. Illustratively, the coordinates herein may be coordinates in a plane coordinate system established with the upper left corner of the in-vehicle screen as the origin.

Each touch position acquisition operation in step S201 may correspond to one piece of time information. The time information corresponding to each touch position acquisition operation is used for determining the duration of the touch operation at the execution time of the touch position acquisition operation.

Illustratively, the time information may include duration information determined by a time corresponding to a pressing operation in the present touch operation and an execution time of the present touch position acquisition operation. The time length information can be regarded as the time length information of the current touch position acquisition operation.

For example, the time of the pressing operation is time ase:Sub>A, the execution time of the secondary touch position acquisition operation is time B, and the duration information may be B-ase:Sub>A.

The first time information of the countercontrol data may include a duration of the touch position obtaining operation corresponding to the countercontrol data.

In some embodiments, the first time information includes a first time and a second time, the first time is a time when the pressing operation in the touch operation is detected, and the second time is an execution time of the touch position acquisition operation.

In these embodiments, the time information of each touch location acquisition operation may include a first time and a second time. The first time corresponding to each touch position obtaining operation may be the time when the pressing operation is detected, and the second time may be the execution time of the touch position obtaining operation.

In these embodiments, the first time information including the first time and the second time is sent to the terminal device, and the duration of the touch operation corresponding to the countercontrol data on the vehicle-mounted screen is calculated by the terminal device through the first time and the second time, so that the calculation amount of the vehicle-mounted host can be reduced, and the resource occupation of the vehicle-mounted host can be reduced.

In some application scenarios, in order to reduce the amount of data sent to the terminal device, so as to reduce the occupation of the vehicle-mounted host resources, instead of generating corresponding inverse control data for each touch position acquisition operation, inverse control data is generated for a plurality of touch position acquisition operations at intervals.

In these application scenarios, each of the above-mentioned countercontrol data may be generated based on the position information acquired by the touch position acquisition operation closest to the time of generating the countercontrol data. Correspondingly, the first time information in the countercontrol data may be time information corresponding to the last touch position acquisition operation.

In some embodiments, for a feedback data, the displacement determined by the position information in the feedback data is positively correlated with the duration indicated by the first time information in the feedback data; the displacement is determined by a position in the position information and an initial position, and the initial position is a position corresponding to a pressing operation in the touch operation.

In these embodiments, the touch operation may be a sliding operation. The pressing operation here may be a pressing operation in a sliding operation. The initial position may be a position obtained from the in-vehicle screen by performing the touch position obtaining operation when a pressing operation in the touch operation is received.

For each of the reverse control data, the position in the reverse control data may be differenced from the initial position, and the displacement (sliding distance) corresponding to the reverse control data may be determined.

During the sliding operation, the sliding distance will increase with increasing duration of the sliding operation.

In these embodiments, the touch operation is determined to be the sliding operation when the displacement determined by the position information and the duration determined by the first time information are determined to be in positive correlation by the position information and the first time information in each of the reverse control data.

S203, sequentially sending at least one piece of reverse control data to the terminal equipment, so that the terminal equipment performs the following response operation on each piece of reverse control data: determining second time information of the local terminal according to the duration time and the initial time determined by the first time information in the reverse control data; and determining response information according to the second time information and the position information in the reverse control data, wherein the initial moment is the moment when the terminal equipment receives the reverse control data corresponding to the pressing operation in the touch operation.

The vehicle-mounted host can sequentially send the at least one reverse control data to the terminal equipment according to a wired or wireless communication connection mode.

In practice, the inverse control data sequence may be generated according to the generation time of each inverse control data. And transmitting the reverse control data in the reverse control data sequence sequentially from first to last according to the generation time.

The terminal device may perform the above-described response operation on each of the reverse control data when receiving the reverse control data.

The terminal device controlling the on-vehicle screen to display the target display content may include the terminal device transmitting the target display content to the on-vehicle screen, and displaying the target display content by the on-vehicle screen.

In this embodiment, at least one touch position acquisition operation is performed in response to receiving a touch operation performed on the vehicle-mounted screen; generating at least one piece of reverse control data comprising first time information and position information according to the position information acquired by at least one touch position acquisition operation; the position information of the reverse control data comprises a position acquired by a primary touch position acquisition operation corresponding to the reverse control data; the first time information is used for determining the duration of the touch operation during the touch position acquisition operation; at least one piece of reverse control data is sequentially sent to the terminal equipment, so that the terminal equipment can execute the following response operation on each piece of reverse control data: determining second time information of the local terminal according to the duration time and the initial time determined by the first time information in the reverse control data; and determining response information according to the second time information and the position information in the reverse control data, wherein the initial moment is the moment when the terminal equipment receives the reverse control data corresponding to the pressing operation in the touch operation. Because the first time information is used for determining the duration of the touch operation when each piece of reverse control data is generated, the second time information determined by the first time information filters the data transmission time from the vehicle-mounted host to the terminal equipment; even if the data transmission takes a long time, the terminal device can obtain the time information of the real touch screen behavior. Therefore, the touch response determined by the terminal equipment according to the second time information and the position information is not abnormal. In addition, the overall response determined by the second time information and the position information corresponding to each of the counter control data is smooth. The problems of errors, unsmooth overall response and frame jumping of the response of the terminal equipment to the reverse control data caused by the interference of the time used for data transmission are solved. The user experience may be improved.

In some embodiments, the step 202 includes the steps of:

firstly, at least one first reverse control event is generated according to at least one touch position acquisition operation.

Next, for each first override event, one override data corresponding to the first override event is generated.

In these embodiments, the first override event herein may include a press down event, a slide event, and a lift up event.

The vehicle-mounted host can package the position information and the time information corresponding to at least one touch position acquisition operation into a first reverse control event. For example, a press event (action_down event) is generated based on the acquired press operation position information and time information. For the touch position acquisition operation in the sliding operation process, a first countercontrol event can be generated every preset number of touch position acquisition operations. For a first override event, at least one sub-event may be included in the first override event. The at least one sub-event may be present in a sub-event list. Each sub-event may correspond to a touch location acquisition operation from a previous first counter-control event to the first counter-control event. Because the touch position obtaining operations are sequentially executed according to time, the sub events can be sequentially arranged in the sub event list according to the sequence of the execution time of the corresponding touch position obtaining operations.

For the sliding operation, the execution body may execute the touch position acquisition operation a plurality of times during the sliding process. In the sliding process, the executing body can acquire operation at preset times of touch position intervals, and encapsulates a sliding event (action_move event). Each sliding event may include a plurality of sub-events arranged in time sequence. Each sub-event corresponds to a touch position acquisition operation between the sliding event and the previous sliding event. Thus, each sub-event may include the position information acquired by the touch position acquisition operation corresponding to the sub-event and the time information corresponding to the touch position acquisition operation.

For the lift operation, the execution body may generate a lift event (action_up event) based on the acquired lift operation position information and time information.

And each operation is packaged into an event, so that event processing is facilitated by using an event response mechanism of the vehicle-mounted host operating system.

In some application scenarios, for each first countercontrol event, countercontrol data corresponding to the first countercontrol event is generated according to a sub-event in the first countercontrol event.

In these application scenarios, the sub-event may be any one of at least one sub-event corresponding to the first countercontrol event. Illustratively, the sub-event may be a latest sub-event corresponding to a time in the plurality of sub-events corresponding to the first countercontrol event.

In these application scenarios, for a first override event comprising a plurality of sub-events, override data for the first override event is generated from one of the sub-events. The data volume sent to the terminal equipment can be reduced, and the occupation of the resources of the vehicle-mounted host computer is reduced.

In some embodiments, the step 202 includes the steps of:

firstly, generating at least one first reverse control event according to at least one touch position acquisition operation; each first opposite control event comprises at least one sub event, and one sub event corresponds to a touch position acquisition operation between the last first opposite control event and the first opposite control event.

And secondly, generating the inverse control data corresponding to at least one sub-event for at least one sub-event of each first inverse control event respectively.

The vehicle-mounted system can package the position information and the time information corresponding to at least one touch position acquisition operation into a first reverse control event. For the touch position acquisition operation in the sliding operation process, a first countercontrol event can be generated every preset number of touch position acquisition operations. For a first override event, at least one sub-event may be included in the first override event. The at least one sub-event may be sequentially arranged in the sub-event list according to the sequence of the execution time of the corresponding touch position acquisition operation.

For each first countercontrol event, generating countercontrol data corresponding to at least one sub-event in the first countercontrol event respectively.

Specifically, for each sub-event, inverse control data corresponding to the sub-event may be generated. Each sub-event may correspond to one of the override data. In this way, the first control event may correspond to a plurality of inverse control data.

And sequentially sending the plurality of reverse control data corresponding to the first reverse control event to the terminal equipment. So that the terminal device responds according to the countercontrol data.

In the application scenes, the reverse control data corresponding to each sub-event in the first reverse control event are generated and sent to the terminal equipment, so that the terminal equipment can generate finer response information according to the reverse control data, and further the problem of frame jumping caused by event deletion in response of the terminal equipment to touch operation can be solved.

Referring to fig. 3, fig. 3 is a schematic diagram of a second embodiment of the disclosure. The back control method for vehicle-mounted display provided by the embodiment is applied to terminal equipment, the terminal equipment is in communication connection with a vehicle-mounted host, and a vehicle-mounted screen of the vehicle-mounted host displays display content transmitted by the terminal equipment. As shown in fig. 3, the method includes:

S301, receiving current reverse control data sent by a vehicle-mounted host, wherein the reverse control data is generated by the vehicle-mounted host in response to receiving touch position acquisition operation executed by touch operation on a vehicle-mounted screen, the current reverse control data comprises first time information and position information, and the position information comprises a position acquired by one touch position acquisition operation corresponding to the current reverse control data; the first time information is used for determining duration of the touch operation in the touch position acquisition operation.

The terminal device here may be various terminal devices such as a mobile terminal, a laptop, a personal digital assistant, etc.

The vehicle-mounted screen can detect touch operation of a user in real time. And determining a touch position according to the touch operation of the user.

The system application on the vehicle-mounted host computer can monitor whether touch operation occurs on the vehicle-mounted screen in real time. A touch operation (e.g., a pressing operation is monitored) occurs on the in-vehicle screen, and the touch position may be acquired from the in-vehicle screen a plurality of times during the duration of the touch operation. For the in-vehicle host, each time the touch position is acquired from the in-vehicle screen may be regarded as one touch position acquisition operation.

The vehicle-mounted host computer can generate at least one piece of reverse control data comprising first time information and position information according to the position information acquired by at least one touch position acquisition operation; the position information of the reverse control data comprises a position acquired by a primary touch position acquisition operation corresponding to the reverse control data; the first time information is used for determining duration of the touch operation in the touch position acquisition operation.

Specifically, the specific implementation of generating the feedback data by the vehicle-mounted host machine may refer to the relevant portion of the embodiment shown in fig. 2, which is not described herein.

The in-vehicle host computer can send each reverse control data to the terminal device.

S302, determining second time information corresponding to the current reverse control data according to the duration time determined by the first time information and an initial time, wherein the initial time is the time when the reverse control data corresponding to the pressing operation in the touch operation is received.

The reverse control data corresponding to the pressing operation refers to reverse control data corresponding to the pressing operation in the continuous touch operation, which is received by the terminal device in the continuous touch operation process.

The terminal device may store the initial time as a corresponding pressing operation timestamp of the home terminal (i.e., home terminal DownTime). For the reverse control data received each time, the duration of the touch operation corresponding to the reverse control data can be determined according to the first time information in the reverse control data, and the second time information of the home terminal can be determined according to the home terminal down time and the duration. The second time information is used for determining the touch operation action time of the local terminal corresponding to the reverse control data.

In some embodiments, the step S302 includes the following steps:

firstly, determining duration of touch operation when touch position acquisition operation corresponding to current countercontrol data is executed from first time information.

Second, the sum of the initial time and the duration is taken as a third time.

And finally, generating second time information corresponding to the current inverse control data comprising the initial time and the third time.
