[0048] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.
[0049] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.
[0050] The main solution of the embodiment of the present application is: obtaining reference position information data of the trackball; determining the position accumulation data during the movement of the trackball based on the reference position information data and the trackball movement data; when the position accumulation data is greater than a preset movement threshold, controlling the cursor movement based on the position accumulation data; when the trackball stops moving, if the step of controlling the cursor movement based on the position accumulation data is not triggered during the movement of the trackball, determining whether the position accumulation data reaches a preset low-speed threshold; if the preset low-speed threshold is reached, returning to the step of controlling the cursor movement based on the position accumulation data.
[0051] In the prior art, the method of controlling cursor movement by a trackball uses the same control sensitivity in different scenes, which results in the cursor moving distance and moving speed failing to meet user expectations when the scenes are switched.
[0052] The present application provides a solution, which is to obtain position accumulation data by accumulating the position data of the trackball during its movement; when the position accumulation data is greater than a preset movement threshold, the cursor movement is controlled based on the position accumulation data; if the cursor movement based on the position accumulation data has not been triggered in the process from the start of the movement to the stop of the movement of the trackball, it is determined whether the position accumulation data reaches a preset low-speed threshold; when the preset low-speed threshold is reached, the cursor movement is returned to the step of controlling the cursor movement based on the position accumulation data to achieve the control of the cursor. By setting different thresholds for fast movement and slow movement, the adaptability of the cursor movement control to the scene is improved.
[0053] It should be noted that the execution subject of this embodiment can be a computing service device with data processing, network communication and program running functions, such as a data processing terminal of AR glasses, a server, etc., or an electronic device, a virtual device, etc. that can realize the above functions. The following takes a cursor movement control device (hereinafter referred to as a control device) as an example to illustrate this embodiment and the following embodiments.
[0054] Based on this, the embodiment of the present application provides a cursor movement control method, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the cursor movement control method of the present application.
[0055] In this embodiment, the cursor movement control method includes:
[0056] Step S20, determining the position accumulation data during the movement of the trackball based on the reference position information data and the trackball movement data;
[0057] In some implementations of the present application, the reference position information of the trackball may represent the initial position information or reference position information of the trackball during the user's current command input process. It is understood that the reference position information of the trackball may be the position information represented by the trackball before the user manipulates the trackball to move.
[0058] In some implementations of the embodiments of the present application, the above-mentioned reference position information data can be the initial position information data of the trackball before the user slides the trackball, or the initial position information data of the trackball before it starts moving, and the embodiments of the present application are not limited to this.
[0059] In an implementation manner of the embodiment of the present application, before step S20, the following may be included: step S10, acquiring reference position information data of the trackball.
[0060] It is understandable that the above-mentioned position accumulation data is also the trackball motion data accumulated during the trackball motion process. Exemplarily, the trackball continuously rolls in a certain direction, and the trackball motion data generated by the rolling can be recorded. In some embodiments, the trackball motion data can be used as data for controlling the change of the cursor position.
[0061] In an implementation of the embodiment of the present application, the entire process from when the user starts sliding the trackball to when the user stops sliding the trackball can be divided into several trackball movement processes.
[0062] It should be noted that, in order to realize the movement control of the cursor, a mapping between the trackball movement data and the cursor movement data is provided in the embodiment of the present application. For the movement process of the trackball, when the position of the trackball reaches a preset movement threshold during the movement process, the corresponding direction and distance of the cursor movement can be controlled based on the mapping relationship between the preset movement threshold and the cursor movement data. That is, in step S30, when the position accumulation data is greater than the preset movement threshold, the cursor movement control is performed based on the position accumulation data.
[0063] It can be understood that the embodiments of the present application do not limit the specific value of the preset movement threshold and the specific correspondence between the trackball motion data and the cursor movement data, and can be modified according to the sensitivity requirements in actual applications.
[0064] In one implementation of the embodiment of the present application, when the control device has performed cursor movement control based on the position accumulation data, the position accumulation data can be initialized to enter the next trackball movement process. Specifically, the method also includes:
[0065] If the step of controlling the cursor movement based on the position accumulation data is triggered, the position accumulation data is initialized;
[0066] When the position accumulation data initialization is completed, the current trackball movement process ends.
[0067] In an implementation of the embodiment of the present application, there may be a situation that the position accumulation data does not exceed the preset movement threshold value during the entire process from the user starting to slide the trackball to the user stopping sliding the trackball. In this case, there is only one trackball movement process, that is, the entire process from the user starting to slide the trackball to the user stopping sliding the trackball.
[0068] Based on the above situation, in the embodiment of the present application, the method further includes:
[0069] Step S40, when the trackball stops moving, if the step of controlling the cursor movement based on the position accumulation data is not triggered during the movement of the trackball, it is determined whether the position accumulation data reaches a preset low-speed threshold.
[0070] Step S50: if the preset low speed threshold is reached, the process returns to the step of controlling the cursor movement based on the position accumulation data.
[0071] It should be noted that in different application interfaces of AR glasses or computers, the corresponding interface resolution, button quantity, button size, etc. are different, so the cursor sensitivity requirements in different application interfaces are also different. For different application interfaces, the corresponding preset movement thresholds can be the same or different, and the embodiments of the present application are not limited to this.
[0072] For example, when AR glasses are used, one application scenario is data input through a virtual keyboard, and another application scenario is the selection of an application mode.
[0073] In one implementation of the embodiment of the present application, for different application interfaces, the corresponding trackball sensitivity may be different, that is, the preset movement thresholds corresponding to different application interfaces are different. At the same time, a preset low-speed threshold may be set for each application interface. The preset low-speed threshold may be the preset movement threshold corresponding to the previous application interface after the application interface is switched, or may be a set dynamic value, such as one tenth of the preset movement threshold of the current application interface after the application interface is switched, or a fixed value, which is not limited by the embodiment of the present application.
[0074] It is understandable that, for application interfaces that require fine control, such as data input through a virtual keyboard, the number of interactive buttons included is relatively large, the button size is relatively small, and the button layout is relatively dense; while for application interfaces that do not require fine control, such as application mode selection, the number of interactive buttons included is relatively small, the button size is relatively large, and the button layout is relatively sparse. The control sensitivity of the trackball in the application interface that requires fine control needs to be lower than that of the application interface that does not require fine control. However, when switching from an application interface that requires fine control to an application interface that does not require fine control, due to the user's operating habits, the user may still control the cursor in the same way as the previous application interface (that is, the application interface that requires fine control). In this way, the accumulated position data generated by the user sliding the trackball may not reach the preset movement threshold of the current application interface (that is, the application interface that does not require fine control). In this case, the cursor cannot move with the user's control, resulting in the cursor moving distance and moving speed not being able to meet the user's expectations when the scene is switched, which reduces the user's experience and even causes the user to misunderstand that the device is damaged.
[0075] The embodiment of the present application obtains the reference position information data of the trackball; determines the position accumulation data during the movement of the trackball based on the reference position information data and the trackball movement data; when the position accumulation data is greater than the preset movement threshold, controls the movement of the cursor based on the position accumulation data; when the trackball stops moving, if the step of controlling the movement of the cursor based on the position accumulation data is not triggered during the movement of the trackball, determines whether the position accumulation data reaches the preset low-speed threshold; if the preset low-speed threshold is reached, returns to the step of controlling the movement of the cursor based on the position accumulation data. By setting the preset low-speed threshold, when the position accumulation data of the trackball does not reach the preset movement threshold, determines whether the preset low-speed threshold is reached; if the preset low-speed threshold is reached, controls the movement of the cursor based on the position accumulation data, thereby realizing fast movement and slow movement of the trackball control.
[0076] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the above-mentioned embodiment 1 can be referred to the above introduction, and will not be repeated in the following. Figure 2 In an embodiment of the present application, the step of determining the position accumulation data during the movement of the trackball based on the reference position information data and the trackball movement data includes:
[0077] Step S22, obtaining current relevant position data of the trackball within the current position accumulation period;
[0078] Step S23, determining the current trackball motion data within the current position accumulation period based on the current relevant position data and the relevant position data of the previous period;
[0079] Step S24, iteratively updating the initial position accumulation data according to the current trackball motion data to obtain updated position accumulation data.
[0080] In practical applications, the trackball can send position information data to the control device at intervals of a preset time period. In some embodiments of the present application, the step S21 is also included, determining the position accumulation period of the trackball during the movement process based on the data reporting period of the trackball. The time length of the above data reporting period is the above interval preset time period.
[0081] It is understandable that, in the overall process from the user starting to slide the trackball to the user stopping sliding the trackball, there may be several continuous data reporting cycles, during which the trackball will report the current relevant position data to the control device. Similarly, the control device has a position accumulation cycle of the same length corresponding to the data reporting cycle of the trackball. In each position accumulation cycle, the control device can determine the current trackball motion data in the current compensation accumulation cycle based on the received current relevant position data and the relevant position data of the previous cycle.
[0082] It should be noted that, during the entire process of the trackball movement, the control device is provided with a position accumulation data, and the position accumulation data can record the movement stroke of the trackball when the user slides the trackball. Before the trackball moves, the control device can initialize the position accumulation data. During the entire process of the trackball movement, the control device can accumulate the trackball displacement generated in a position accumulation cycle to update the position accumulation data, and use the iteratively updated position accumulation data as the initial position accumulation data of the next position accumulation cycle, thereby accumulating the trackball displacement in each position accumulation cycle during the entire process of the trackball movement.
[0083] In an implementation of the embodiment of the present application, the step of iteratively updating the initial position accumulated data according to the current trackball motion data to obtain the updated position accumulated data includes:
[0084] Determine the current trackball motion direction of the current position accumulation period based on the current trackball motion data;
[0085] Determine the historical trackball movement direction of the trackball based on the historical trackball displacement corresponding to the initial position accumulation data;
[0086] If the current trackball movement direction is consistent with the historical trackball movement direction, the current trackball movement data and the historical trackball displacement are accumulated to obtain updated position accumulation data;
[0087] If the current trackball movement direction is inconsistent with the historical trackball movement direction, the current trackball movement data is used as updated position accumulation data.
[0088] It should be noted that there may be some misoperations during the process of the user controlling the trackball movement. For example, during the current position accumulation period, the current trackball movement data determined by the control device is -10mm, while the position accumulation data recorded by the control device at this time is 10mm. In this case, directly accumulating the trackball displacements of the two position accumulation periods will result in the final cursor movement not meeting the user's expectations.
[0089] In the embodiment of the present application, the motion direction of the trackball in the current position accumulation period can be determined based on the current trackball motion data; and the motion direction of the trackball in the historical position accumulation period can be determined based on the historical trackball displacement corresponding to the initial position accumulation data. By comparing the current trackball motion direction with the historical trackball motion direction, when the directions are consistent, the current trackball motion data and the historical trackball displacement can be accumulated to obtain updated position accumulation data; when the directions are inconsistent, the historical trackball displacement can be considered as the displacement caused by misoperation, and the current trackball motion data can be directly used as the updated position accumulation data.
[0090] The embodiment of the present application determines the position accumulation period of the trackball during the movement process based on the data reporting period of the trackball; obtains the current relevant position data of the trackball in the current position accumulation period; determines the current trackball movement data in the current position accumulation period based on the current relevant position data and the relevant position data of the previous period; determines the current trackball movement direction of the current position accumulation period based on the current trackball movement data; determines the historical trackball movement direction of the trackball based on the historical trackball displacement corresponding to the initial position accumulation data; if the current trackball movement direction is consistent with the historical trackball movement direction, the current trackball movement data and the historical trackball displacement are accumulated to obtain the updated position accumulation data; if the current trackball movement direction is inconsistent with the historical trackball movement direction, the current trackball movement data is used as the updated position accumulation data. Since the movement direction of the trackball in the current position accumulation period and the historical position accumulation period is compared, the erroneous operation in the cursor control is filtered, and the accuracy of the cursor control is improved.
[0091] Based on the first embodiment and / or the second embodiment of the present application, in the third embodiment of the present application, the same or similar contents as those of the above-mentioned first embodiment and / or the second embodiment can refer to the above introduction, and will not be repeated later. Figure 3 The step of obtaining the current relevant position data of the trackball within the current position accumulation period includes:
[0092] Step S100, obtaining initial relevant position data of the trackball in the current position accumulation period;
[0093] Step S200, filtering the initial relevant position data to obtain current relevant position data.
[0094] It is understandable that during the movement of the trackball, due to reasons such as sensor accuracy and environmental interference, certain noise may exist in the acquired initial relevant position data, thereby causing deviation in the position data and affecting the accuracy of cursor control.
[0095] It should be noted that, in order to avoid interference of noise data on cursor control, the embodiment of the present application can filter the data when the initial relevant position data is acquired to obtain the current relevant position data.
[0096] In an implementation of the embodiment of the present application, after the step of iteratively updating the position accumulated data according to the current trackball motion data to obtain the updated position accumulated data, the method further includes:
[0097] When the position accumulation data is not greater than the preset movement threshold, the method returns to the step of obtaining the current relevant position data of the trackball in the current position accumulation period in the next position accumulation period.
[0098] It is understandable that when the position accumulation data is not greater than the preset movement threshold, the position information data received in the next position accumulation period can be waited for accumulation until the position accumulation data is greater than the preset movement threshold or the trackball no longer reports position information data.
[0099] The low-speed judgment logic of the embodiment of the present application solves the problem that the user operates the trackball, but the stroke of the operation trackball is short and does not reach the preset movement threshold of the moving cursor, resulting in the cursor not moving, and the user feels that the operation is not effective. The present application observes similar events in actual applications and knows that when the user does not get feedback in one operation (i.e., the first position accumulation period), the user usually performs a second operation (i.e., the second position accumulation period). Therefore, when the trackball stroke is too short and no feedback is obtained, the current trackball rolling direction and rolling stroke relative to the trackball before this operation (i.e., the current trackball movement direction and current trackball movement data) are recorded. In the second operation, it is first determined whether the rolling direction is consistent with the first operation; when the trackball rolling direction of the second operation is consistent with the trackball rolling direction of the first operation, the rolling stroke of the second operation is accumulated on the basis of the rolling stroke of the first operation, and the cursor movement is triggered when the rolling stroke reaches the preset movement threshold. At the same time, the position of the trackball when the cursor moves is used as the reference position of the next cursor movement (i.e., the reference position information data), and the accumulated rolling stroke is initialized to perform the next operation judgment. When the trackball rolling directions of the first operation and the second operation are inconsistent, the data of the first operation is not referenced. The position information of the trackball before the second operation is used as the reference position information data, and the displacement in the operation is used as the position accumulation data to determine whether the trackball operation reaches the cursor movement threshold.
[0100] The embodiment of the present application obtains the initial relevant position data of the trackball within the current position accumulation period and performs filtering on the initial relevant position data to obtain the current relevant position data. Since the position data is filtered, the accuracy of cursor control is improved.
[0101] This application also provides a cursor movement control device, please refer to Figure 4 , the cursor movement control device comprises:
[0102] A data acquisition module 10 is used to acquire reference position information data of the trackball;
[0103] A data accumulation module 20, for determining position accumulation data during the movement of the trackball based on the reference position information data and the trackball movement data;
[0104] A cursor control module 30, configured to control cursor movement based on the position accumulation data when the position accumulation data is greater than a preset movement threshold;
[0105] The speed determination module 40 is used to determine whether the position accumulation data reaches a preset low speed threshold when the trackball stops moving and if the step of controlling the cursor movement based on the position accumulation data is not triggered during the movement of the trackball;
[0106] The cursor control module 30 is further configured to return to the step of controlling the cursor movement based on the position accumulation data if a preset low speed threshold is reached.
