However, due to network fluctuation or congestion, the mouse movement signal sent to the server by the user is not the mouse movement signal acquired by the client, as shown in fig. 2, the time sequence of the mouse movement signal 1 received by the server does not arrive according to the time sequence acquired by the client due to network fluctuation 2, and at this time, the user can obviously feel the jitter of mouse operation, and the user experience is reduced.
In order to solve the technical problem, the invention provides a mouse jitter control method, which is characterized in that the current mouse coordinate of a received mouse movement signal is subjected to jitter compensation at a server side to obtain a smooth mouse movement track, thereby reducing the influence of network fluctuation or blockage on mouse jitter and improving user experience.

In this step, the client sends a mouse movement signal to the server, and the client may be an electronic device such as a computer, a smart phone, a tablet computer, and a smart wearable device. The server receives a mouse movement signal sent by the client, and needs to judge whether the received mouse movement signal is a jittering mouse movement signal, that is, a mouse movement signal sent when the mouse movement signal is a mouse jitter.
Step S302, according to the shaking mouse moving signal, determining the acceleration and the speed of the shaking mouse moving signal.
In the step, the server only needs to determine the acceleration and the speed of the mouse movement signal when the mouse shakes, so that the current mouse coordinate of the mouse movement signal can be corrected according to the movement trend of the mouse, and shake compensation can be timely performed when the mouse shakes.
Step S303, judging whether the next mouse moving signal is received within the preset time length of the received jittered mouse moving signal.
In this step, the server receives a mouse movement signal sent by the client when the mouse movement signal is a mouse movement signal sent by the client when the mouse is jittered, and determines whether a next mouse movement signal is received within a preset time period after the time when the jittered mouse movement signal is received, so as to correct the current mouse coordinate of the jittered mouse movement signal according to the receiving condition of the next mouse movement signal, wherein the preset time period can be flexibly set as required, and is not specifically limited herein.
And step S304, if the next mouse moving signal is not received, determining the current mouse coordinate after being used as the shake mouse moving signal correction according to the acceleration and the speed of the shake mouse moving signal.
In the step, the server does not receive the next mouse moving signal within the preset time length of receiving the jittering mouse moving signal, that is, the data transmission is unstable due to reasons of packet loss, network delay, network fluctuation, blocking and the like, the server does not receive the next mouse moving signal in time, the server determines the acceleration and the speed of the jittering mouse moving signal, that is, determines the mouse moving trend of the current mouse moving signal, and corrects the current mouse coordinate of the jittering mouse moving signal according to the mouse moving trend so as to realize the jittering compensation of the current mouse coordinate.
In one example, the current mouse movement coordinate is predicted according to the acceleration and the speed of the shake mouse movement signal, and the predicted current mouse movement coordinate is determined as the current mouse coordinate after the shake mouse movement signal is corrected.
And S305, rendering the game picture according to the current mouse coordinate and sending the rendered picture to the client.
In the step, the server corrects the current mouse coordinate of the mouse movement signal to finish the smooth processing of mouse shake, renders a game picture according to the current mouse coordinate, sends the rendered picture to the client, optimizes the picture feedback of the mouse movement signal by the server, effectively reduces the difference between the mouse movement feedback of the user and the cloud game picture, and improves the user experience.
In the embodiment of the invention, the server receives a mouse movement signal sent by the client and determines that the received mouse movement signal is a jittering mouse movement signal, the mouse movement signal sent by the client is transmitted to the server within a certain time due to the blockage of network connection, the server cannot receive the next mouse movement signal, the server predicts the current mouse coordinate of the jittering mouse movement signal according to the acceleration and the speed of the jittering mouse movement signal, the predicted current mouse coordinate is used as the current mouse coordinate after the jittering mouse movement signal is corrected, a game picture is rendered according to the corrected current mouse coordinate and the rendered picture is sent to the client, and the difference between the mouse movement feedback of the user and the cloud game picture is reduced. The embodiment of the invention only corrects the current mouse moving coordinate in time when the mouse shakes, effectively improves the mouse shaking sense of the client caused by network problems and improves the game experience.
According to an exemplary embodiment, as shown in fig. 4, the method in the embodiment of the present invention is applied to a server. The method in the embodiment of the invention comprises the following steps:
and S401, receiving a mouse moving signal.
In this step, the server receives a mouse movement signal sent by the client, where the current mouse movement signal may be a mouse movement signal sent when the client mouse shakes.
Step S402, judging whether a mouse moving signal is received at a preset sampling point or not; if not, executing step S403; if yes, go to step S408.
In the step, when the server is connected to a mouse moving signal sent by the client, whether the moment of receiving the mouse moving signal is the moment of a preset sampling point is judged to determine whether the mouse moving signal is the mouse moving signal sent when the mouse shakes, when the mouse moving signal is not the mouse moving signal sent when the mouse shakes, a game picture can be directly rendered according to the mouse moving signal, and when the mouse moving signal is judged to be the mouse moving signal sent when the mouse shakes, shake compensation needs to be carried out on the mouse moving signal, so that the shake sense of mouse control felt by a user is reduced, and the user experience is improved.
The preset sampling point can be set according to the constant acquisition frequency when the client acquires the mouse movement signal, for example, the preset sampling point is the same as the constant acquisition frequency of the client, the service judges whether the mouse movement signal is received at the preset sampling point, that is, the server judges whether the received mouse movement signal arrives according to the time sequence of acquiring the mouse movement signal by the client, if the mouse movement signal arrives according to the time sequence of acquiring the mouse movement signal by the client, the mouse of the user generates a shaking sense, and if the mouse movement signal does not arrive according to the time sequence of acquiring the mouse movement signal by the client, the mouse of the user is shaken.
Step S403, determining the mouse movement signal as a jittered mouse movement signal.
In the step, the server judges that the moment of receiving the mouse moving signal is inconsistent with the moment of the preset sampling point, and determines that the mouse moving signal is a jittered mouse moving signal, namely the mouse is jittered.
And S404, determining the acceleration and the speed of the shaking mouse moving signal according to the shaking mouse moving signal.
Step S405, judging whether a next mouse moving signal is received within a preset time length since the jittered mouse moving signal is received; if not, go to step S406; if yes, go to step S407.
And step S406, determining the current mouse coordinate corrected as the shaking mouse moving signal according to the acceleration and the speed of the shaking mouse moving signal.
Step S405 is the same as step S303, and step S406 is the same as step S304, which are described in step S303 and step S304, and are not repeated herein.
And step S407, determining the current mouse coordinate corrected as the shaking mouse movement signal according to the acceleration and the speed of the shaking mouse movement signal and the position information of the next mouse movement signal.
In the step, the server may receive a next mouse moving signal in advance from within a preset time period during which the jittered mouse moving signal is received, the server determines the acceleration and the speed of the jittered mouse moving signal and the position information of the next mouse moving signal, that is, determines the mouse moving trend of the current mouse moving signal, and corrects the current mouse coordinate of the jittered mouse moving signal in time according to the mouse moving trend and the position information of the next mouse moving signal, so that the mouse moving coordinate is smoothly processed at the server, and the continuity of the mouse moving signal of the server is optimized.
In one example, the current mouse movement coordinate of the shake mouse movement signal is interpolated according to the acceleration and the speed of the shake mouse movement signal and the position information of the next mouse movement signal, and the current mouse movement coordinate obtained by the interpolation is used as the current mouse coordinate after the shake mouse movement signal is corrected. In this embodiment, the server receives a mouse movement signal sent by the client and determines that the received mouse movement signal is a jittered mouse movement signal, and when the mouse movement signal sent by the client is transmitted to the server within a certain time, the server receives a next mouse movement signal, and according to the acceleration and the speed of the jittered mouse movement signal and the position information of the next mouse movement signal, the server performs interpolation operation on the current mouse coordinate of the jittered mouse movement signal to obtain a corrected current mouse coordinate, renders a game picture according to the corrected current mouse coordinate, and sends the rendered picture to the client, so as to reduce the difference between the mouse movement feedback of the user and the cloud game picture, and improve the game experience of the user.
And step S408, rendering the game picture according to the current mouse coordinate and sending the rendered picture to the client.
Step S408 is the same as step S305, and is described in step S305, which is not described herein again.
And step S409, storing the current mouse coordinates to a historical track queue.
In the step, the server corrects the mouse moving signal sent when the mouse shakes, then caches and utilizes the corrected mouse moving signal, provides compensation reference information for the compensation and correction of the shaking mouse moving signal generated when the mouse shakes again, and provides more accurate data for mouse track prediction through the historical track of the mouse.
In the embodiment of the invention, when the server is connected to the mouse moving signal sent by the client and judges that the mouse moving signal sent by the client is a jittering mouse moving signal, whether the next mouse moving signal is received or not within a certain time length from the moment of receiving the jittering mouse moving signal is further judged, so that a corresponding correction mode is provided for the current mouse coordinate of the jittering mouse moving signal according to the receiving condition of the next mouse moving signal, the jittering compensation is carried out on the current mouse coordinate of the received mouse moving signal, the influence of network fluctuation or blockage on the mouse jittering is reduced, and the user experience is improved.
