[0002] In daily life and work, the use of the mouse is widespread. The mouse replaces the cumbersome keyboard commands, making computer operation much simpler. However, the mouse's movement speed often affects users' performance requirements. Currently, we mainly adjust the mouse speed by going to Start > Control Panel > Printers and Other Hardware Devices > Mouse, and then clicking "Apply." This process often requires several attempts to find a suitable speed. Different computer applications require different mouse speeds, and adjusting the speed in the control panel every time is time-consuming and involves too many trial and error attempts.

[0017] The embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0018] In the following description, specific details such as particular system architectures, interfaces, and technologies are presented for illustrative purposes rather than for limiting purposes, in order to provide a thorough understanding of this application.

[0019] In this document, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " generally indicates that the preceding and following related objects have an "or" relationship. Furthermore, "many" in this document means two or more. Moreover, the term "at least one" in this document means any combination of at least two of any one or more of a plurality of objects. For example, including at least one of A, B, and C can mean including any one or more elements selected from the set consisting of A, B, and C.

[0020] Please see Figure 1 , Figure 1 This is a flowchart illustrating an embodiment of the mouse movement speed adjustment method of this application. Figure 1 As shown in the embodiments of this disclosure, the mouse movement speed adjustment method may include the following steps:

[0021] Step S11: Obtain the first speed and the second speed of the mouse within a preset time period. The first speed is determined by the distance traveled by the mouse within the preset time period, and the second speed is determined by the displacement of the mouse within the preset time period.

[0022] For example, the first speed may be the average speed determined by the distance within a preset time period, and the second speed may be the average speed determined by the displacement within a preset time period.

[0023] Step S12: Determine the mouse motion type based on the relationship between the first speed and the second speed.

[0024] Generally, if the mouse moves in a single linear direction within a preset time period, the magnitudes of its first and second velocities should be equal. If the mouse moves back and forth within the preset time period, the distance traveled during that time period is greater than the corresponding displacement; in this case, the first velocity is greater than the second velocity. Alternatively, if the mouse moves in a curved path within the preset time period, the distance traveled during that time period is greater than the corresponding displacement; in this case, the first velocity is greater than the second velocity. Therefore, the relationship between the first and second velocities can be used to determine whether the mouse is moving in a single linear direction or engaging in other types of motion.

[0025] Step S13: Select the target speed corresponding to the motion type from the first speed and the second speed, and adjust the mouse movement speed.

[0026] Specifically, adjusting the mouse movement speed as described in this embodiment can be achieved by adjusting the mouse's dpi.

[0027] For example, a target speed can be preset for each type of movement. The correspondence between the target speed and the mouse movement speed can be predefined. After the target speed is determined, the mouse movement speed can be adjusted based on the correspondence between the target speed and the mouse movement speed.

[0028] The above solution determines the mouse's movement type by acquiring the first speed determined by distance and the second speed determined by displacement within a preset time period. Then, it selects the corresponding target speed based on the mouse's movement type to adjust the mouse's movement speed. This eliminates the need to enter the console to adjust the mouse speed, thus improving the efficiency of mouse speed adjustment.

[0029] In some disclosed embodiments, step S11 above may include the following steps:

[0030] The mouse's movement trajectory within a preset time period is obtained. Then, based on the movement trajectory, the mouse's distance traveled and displacement within the preset time period are determined. Finally, the quotient between the path length and the preset time period is used as the first velocity, and the quotient between the displacement and the preset time period is used as the second velocity.

[0031] Here, "motion trajectory" refers to the movement path of the mouse on the display screen. One way to determine the mouse's distance over a preset time period based on the motion trajectory is to divide the trajectory into numerous sub-segments, determine the length of each sub-segment, and add the lengths of all sub-segments together to obtain the corresponding distance. "Displacement" refers to the line connecting the starting and ending points of the motion trajectory.

[0032] In some disclosed embodiments, the motion type includes a first motion type and a second motion type. Step S12 above may include the following steps:

[0033] Obtain the target speed difference between the first speed and the second speed. In response to the target speed difference being less than or equal to a preset speed difference, determine the mouse movement type as the first movement type. Where the target speed difference between the first speed and the second speed is less than or equal to the preset speed difference, it can be considered that the mouse is performing unidirectional linear motion within a preset time period.

[0034] In response to a target speed difference exceeding a preset speed difference, the mouse movement type is determined to be the second movement type. Optionally, the second movement type includes a first sub-movement type and a second sub-movement type. Please also refer to... Figure 2 , Figure 2 This is a schematic flowchart illustrating the process of determining a first sub-motion type in one embodiment of the mouse movement speed adjustment method of this application. Figure 2 As shown, the way to determine the mouse's motion type as the second motion type in response to a target speed difference greater than a preset speed difference can be:

[0035] Step S21: In response to the target speed difference being greater than the preset speed difference, the preset time period is divided into a preset number of sub-time periods, and the displacement direction of the mouse in each sub-time period is determined.

[0036] The preset time period is divided into a preset number of sub-time periods. Each sub-time period corresponds to a sub-motion trajectory. The direction of the line connecting the start and end positions of each sub-motion trajectory is used as the displacement direction of the mouse within each sub-time period.

[0037] Optionally, the number of preset time periods can be customized by the user.

[0038] Step S22: Taking one of the displacement directions as the positive direction, classify each displacement direction based on the angle between each displacement direction and the positive direction to obtain several displacement directions belonging to positive displacement and several displacement directions belonging to negative displacement.

[0039] For example, displacement directions with an angle less than or equal to a preset angle relative to the positive direction are considered positive displacements, while displacement directions with an angle greater than the preset angle are considered negative displacements. The preset angle can be 90 degrees or the average of the angles between each displacement direction and the positive direction. Positive displacement directions may or may not include those selected as positive directions.

[0040] Step S23: In response to the fact that the distribution between the displacement directions belonging to positive displacement and the distribution between the displacement directions belonging to negative displacement satisfy the preset conditions, determine the mouse motion type as the first sub-motion type.

[0041] For example, determining whether the distribution between displacement directions belonging to positive displacement and the distribution between displacement directions belonging to negative displacement satisfy a preset condition can be done as follows:

[0042] Based on the displacement directions belonging to positive displacement, determine the positive average displacement direction. And based on the displacement directions belonging to negative displacement, determine the negative average displacement direction. For example, divide a preset time period t into 2n segments, designate a certain displacement direction as the positive direction, and let the positive displacements be &0, &1, ..., &n, and the negative displacements be -$0, -$1, ..., -$n. Calculate the positive average displacement direction &plus = (&0 + &1 + ... + &n) / n, and calculate the negative average displacement direction &minus = (-$0 - $1 - ... -$n) / n.

[0043] Based on the positive average displacement direction and all displacement directions belonging to positive displacement, the first standard deviation of the positive displacement is determined. Similarly, based on the negative average displacement direction and all displacement directions belonging to negative displacement, the second standard deviation of the negative displacement is determined. The methods for determining the first standard deviation of the positive displacement and all displacement directions belonging to positive displacement, and the methods for determining the second standard deviation of the negative displacement and all displacement directions belonging to negative displacement, are similar to those used in general statistics for calculating standard deviations, and will not be elaborated upon here.

[0044] In response to the fact that both the first and second standard deviations are less than a preset variance, it is determined that the distribution among the displacement directions belonging to positive displacement and the distribution among the displacement directions belonging to negative displacement satisfy a preset condition. For example, when both the first and second standard deviations are less than the preset variance, the mouse is likely to perform a reciprocating motion within a preset time period. That is, the first sub-motion type provided in this embodiment is a reciprocating motion type.

[0045] In some disclosed embodiments, in response to the fact that the distribution between displacement directions belonging to positive displacement and the distribution between displacement directions belonging to negative displacement do not meet a preset condition, the mouse movement type is determined to be a second sub-motion type. For example, in response to the fact that the first standard deviation and the second standard deviation are not both less than a preset variance, it is determined that the distribution between displacement directions belonging to positive displacement and the distribution between displacement directions belonging to negative displacement do not meet the preset condition.

[0046] In some disclosed embodiments, step S13 above may include the following steps:

[0047] In response to a motion type of either a first motion type or a first sub-motion type, a target speed is determined to be a first speed. And, in response to a motion type of either a second sub-motion type, a target speed is determined to be a second speed. Then, the product of the target speed and a preset conversion rate is used as the new mouse movement speed. For example, if the preset conversion rate is k, and the target speed is the first speed, the new mouse movement speed is the first speed * k; if the target speed is the second speed, the new mouse movement speed is the second speed * k. In some application scenarios, a preset time period is set for adjusting the mouse movement speed during movement, meaning the mouse movement speed is adjusted once every preset time period. An error range can also be set, which can be used to constrain the adjustable range of the new movement speed.

[0048] In some disclosed embodiments, the mouse movement speed adjustment method may further include the following steps:

[0049] In response to the second speed being a preset value, the step of multiplying the target speed by the preset conversion rate as the new mouse movement speed is not performed; instead, the preset movement speed is used as the new mouse movement speed. For example, the preset value can be 0, or other preset values ​​close to 0. If the mouse movement speed is the preset value, it may affect the user's normal mouse movement operation; therefore, a minimum allowed movement speed can be preset as the preset movement speed. When the second speed is 0, the preset movement speed is directly used as the new mouse movement speed.

[0050] To better understand the mouse movement speed adjustment method provided in this disclosure, please refer to... Figure 3 , Figure 3 This is another flowchart illustrating an embodiment of the mouse movement speed adjustment method of this application. Figure 3 As shown, the mouse movement speed adjustment method provided in this embodiment may include the following steps:

[0051] Step S31: Obtain the first and second speeds of the mouse within a preset time period.

[0053] Step S32: Obtain the target speed difference between the first speed and the second speed.

[0054] Step S33: In response to the target speed difference being less than or equal to the preset speed difference, determine the mouse movement type as the first movement type.

[0055] Step S34: Determine the target speed as the first speed, and adjust the mouse movement speed based on the first speed.

[0056] Step S35: In response to the target speed difference being greater than the preset speed difference, the preset time period is divided into a preset number of sub-time periods, and the displacement direction of the mouse in each sub-time period is determined.

[0057] Step S36: Taking one of the displacement directions as the positive direction, classify each displacement direction based on the angle between each displacement direction and the positive direction to obtain several displacement directions belonging to positive displacement and several displacement directions belonging to negative displacement.

[0058] Step S37: Determine the positive average displacement direction based on each displacement direction belonging to positive displacement; and determine the negative average displacement direction based on each displacement direction belonging to negative displacement.

[0060] Step S38: Determine the first standard deviation of the positive displacement based on the positive average displacement direction and each displacement direction belonging to the positive displacement; and determine the second standard deviation of the negative displacement based on the negative average displacement direction and each displacement direction belonging to the negative displacement.

[0061] The specific implementation of step S38 can be found above, and will not be repeated here.

[0062] Step S39: In response to the fact that both the first standard deviation and the second standard deviation are less than the preset variance, determine that the distribution between each displacement direction belonging to positive displacement and the distribution between each displacement direction belonging to negative displacement satisfy the preset condition.

[0063] Step S40: Determine the mouse motion type as the first sub-motion type.

[0064] After executing step S40, step S34 can be executed to adjust the mouse movement speed.

[0065] Step S41: In response to the fact that the first standard deviation and the second standard deviation are not both less than the preset variance, it is determined that the distribution between the displacement directions belonging to positive displacement and the distribution between the displacement directions belonging to negative displacement do not meet the preset conditions.

[0066] Step S42: Determine the mouse motion type as the second sub-motion type.

[0067] Step S43: Determine the target speed as the second speed, and adjust the mouse movement speed based on the second speed.

[0068] The above solution determines the mouse's movement type by acquiring the first speed determined by distance and the second speed determined by displacement within a preset time period. Then, it selects the corresponding target speed based on the mouse's movement type to adjust the mouse's movement speed. This eliminates the need to enter the console to adjust the mouse speed, thus improving the efficiency of mouse speed adjustment.
