Abstract
Description
Technical Field
[0001] This disclosure relates to the field of electronic equipment technology, and in particular to a pointer movement method, apparatus, electronic equipment, medium, and program product. Background Technology
[0002] Pointers are one of the most frequent and fundamental tasks in graphical user interfaces (GUIs). Users can easily control the movement of a pointer on an electronic device screen using input devices such as mice, touchpads, and graphics tablets. The pointer's trajectory on the screen can be the same as the trajectory detected by the input device. The pointer's speed on the screen can be determined by the speed detected by the input device and the control display gain. The control display gain can vary with the speed detected by the input device. The greater the speed detected by the input device, the greater the control display gain, allowing the pointer to travel a greater distance on the screen for the same physical displacement during high-speed movement, thus improving the efficiency of long-distance pointing tasks.
[0003] However, most electronic devices with input devices use scaling based on the Android open-source project, which can improve pointing efficiency to some extent. However, since the pointer movement algorithm is easily affected by hardware characteristics, it is impossible to maintain consistent pointer behavior when users interact on different devices, which reduces the user's swiping responsiveness experience.

[0030] Figure 7 This is a block diagram illustrating an electronic device according to an exemplary embodiment. Detailed Implementation
[0031] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.
[0032] It should be noted that all actions involving the acquisition of signals, information, or data in this disclosure are carried out in compliance with the relevant data protection laws and policies of the country where the location is situated, and with authorization from the owner of the relevant device.
[0033] In related technologies, the movement speed detected by the input device typically refers to the number of pixels moved per unit time. That is, the unit of the movement speed detected by the input device is a virtual unit. Scaling calculations are performed on the movement speed detected by the input device to obtain the movement speed representing the number of pixels the pointer moves on the screen per unit time. However, since the size of each pixel may differ between different input devices or screens, under the same scaling settings, different mapping curves for controlling display gain will appear for different input devices or screens. This leads to inconsistent user experience and reduces the responsiveness of the user's scrolling.
[0034] In view of this, the present disclosure provides a pointer movement method, apparatus, electronic device, medium, and program product. By converting a first movement speed corresponding to a user operation detected by an input device, a second movement speed is obtained to characterize the physical distance moved by the user operation per unit time. Then, a third movement speed characterizing the physical distance the pointer moves on the screen per unit time can be obtained based on a second mobile device and a control display gain function. This ensures that the movement speeds input and output to the control display gain function are both the physical distance moved per unit time, rather than the number of pixels moved per unit time. This avoids the problem of different control display gain mapping curves for different input devices or screens, thus effectively enhancing the compatibility of pointer movement across devices and improving the user's swiping responsiveness.
[0035] Figure 1 This is a schematic diagram illustrating a pointer movement method according to an exemplary embodiment. Figure 1 As shown, a pointer is displayed on screen A. In this disclosure, the pointer may also be referred to as a cursor, pointer, etc. The pointer can have various forms, such as a white arrow, a double arrow, a hand shape, a regularly flashing "I" shape, etc. Figure 1 In the example shown, the pointer is represented by a white arrow. Figure 1 In the diagram, region B represents the touchpad. When a user's finger slides on the touchpad, the pointer's movement on the screen follows the same trajectory as the finger's movement in physical space. For example, if the user's finger moves in a straight line on the touchpad, the pointer simultaneously moves in a straight line on the screen.
[0036] Figure 2 This is a flowchart illustrating a pointer movement method according to an exemplary embodiment. Figure 2 As shown, the pointer movement method may include the following steps.
[0037] In step S21, a second movement speed is determined based on the first movement speed corresponding to the user operation detected by the input device.
[0038] The first movement speed represents the number of pixels moved by the user's operation per unit time, and the second movement speed represents the physical distance moved by the user's operation per unit time.
[0039] The input device can be an input device capable of detecting movement information. The movement information corresponding to the user operation detected by the input device can include the movement trajectory detected by the input device and the movement speed detected by the input device. The movement trajectory detected by the input device can be the movement trajectory generated by the user's operation controlling the input device to move in physical space. In some embodiments, the movement trajectory detected by the input device can also be the movement trajectory generated by the user's finger, pressure-sensitive pen, etc., moving on the input device. The movement speed detected by the input device can be the movement speed of the input device controlled by the user's operation to move in physical space. In some embodiments, the movement speed detected by the input device can also be the movement speed of the user's finger, pressure-sensitive pen, etc., moving on the input device.
[0040] Furthermore, the movement trajectory and speed detected by the input device can also be the movement trajectory and speed of an air gesture. The input device can be a mouse, touchpad, graphics tablet, etc. This application does not limit the specific type of input device.
[0041] The electronic device executing this pointer movement method can determine a second movement speed based on a first movement speed corresponding to the user operation detected by the input device. That is, the first movement speed, which represents the number of pixels moved by the user operation per unit time, is converted into a second movement speed, which represents the physical distance moved by the user operation per unit time. In other words, the first movement speed in units of px / s is converted into a second movement speed in units of mm / s.
[0042] In step S22, a third moving speed is determined based on the second moving speed and the control display gain function. The third moving speed represents the physical distance the pointer moves on the screen per unit time.
[0043] In other words, the input and output of the display gain function are both the speed of movement representing the physical distance moved per unit time, rather than the speed of movement representing the number of pixels moved per unit time. Thus, for different devices, the input and output of the display gain function represent the speed of movement representing the physical distance moved per unit time. Since the physical distance is not affected by hardware characteristics, the curve of controlling the display gain is the same for different input devices or screens, provided that the first movement speed detected by the input device remains unchanged, ensuring a consistent user experience across different electronic devices.
[0044] In step S23, a fourth moving speed is determined based on the third moving speed. The fourth moving speed represents the number of pixels the pointer moves on the screen per unit time.
[0045] In step 24, the pointer is moved across the screen at a fourth moving speed.
[0046] Considering that the position of the pointer on the screen is usually determined by pixels, after obtaining the third moving speed in step S22, which represents the physical distance the pointer moves on the screen per unit time, the third moving speed needs to be converted into a fourth moving speed, which represents the number of pixels the pointer moves on the screen per unit time, and the pointer is moved on the screen at the fourth moving speed.
[0047] By adopting the above technical solution, a second movement speed is obtained by converting the first movement speed detected by the input device to represent the physical distance moved by the user operation per unit time. Then, a third movement speed representing the physical distance the pointer moves on the screen per unit time can be obtained based on the second mobile device and the control display gain function. This ensures that the input and output of the control display gain function are both movement speeds representing the physical distance moved per unit time, rather than movement speeds representing the number of pixels moved per unit time. This effectively enhances the compatibility of pointer movement across devices and improves the user's responsiveness when sliding.
[0048] Figure 3 This is a hardware framework diagram illustrating pointer movement according to an exemplary embodiment. (e.g.) Figure 3As shown, the input device and its co-processing MCU (Microcontroller Unit) collect data and send it to the host SOC (System on Chip) of the electronic device. For example, the input device IC (Integrated Circuit) sends touch-related data corresponding to user operations to the input device MCU via an I2C (Inter-Integrated Circuit) controller. The input device MCU then communicates with the host MCU via a half-duplex UART (Universal Asynchronous Receiver / Transmitter) protocol, sending the touch-related data to the host MCU. Alternatively, the touch-related data may be sent to the data processing unit within the host MCU. This touch-related data may include not only contact positions but also keyboard key values, hall status, power supply chip data, LED status, etc. The data processing unit primarily prioritizes the various data points within the touch-related data to determine which data will be prioritized during subsequent packet assembly. For example, the data processing unit can set the contact position to have the highest priority, meaning that contact positions are prioritized for packet assembly. After data processing, the packet assembly module assembles the processed data into packets according to the input device protocol. Then, the host SOC reads the data packets through the I2C controller to obtain the touch point position. Finally, the host SOC calculates the pointer target position using a pointer acceleration strategy deployed on it, and performs drawing, rendering, and compositing. Finally, the image is sent to the screen module for display via the DSI (Display Serial Interface) controller. The pointer acceleration strategy refers to the strategy for implementing the pointer movement method provided in this disclosure.
[0049] In addition, such as Figure 3 As shown, the hardware framework may also include an input device in-situ Hall sensor. This sensor detects whether the input device is accurately connected to the host and feeds the detection result back to the data processing unit via the input device hot-swap status management module. The data processing unit can then determine whether the input device is accurately connected to the host based on the detection result, and only process the contact-related data if the connection is confirmed.
[0050] To facilitate a better understanding of this disclosure by those skilled in the art, a complete embodiment of the pointer movement method is described below.
[0051] In this disclosure, a first moving speed can be converted into a second moving speed based on relevant parameters of the input device. In one embodiment, Figure 2Step S21, which determines the second movement speed based on the first movement speed corresponding to the user operation detected by the input device, may include: acquiring relevant parameters of the input device; and determining the second movement speed based on the first movement speed and the relevant parameters of the input device.
[0052] When the input device is a touchpad or a digitizer, the relevant parameters of the input device may include the physical size and resolution of the input device, and / or the pixel density of the input device.
[0053] In one embodiment of this example, the relevant parameters of the input device may include the pixel density of the input device. Accordingly, the specific implementation of determining the second moving speed based on the first moving speed and the relevant parameters of the input device is as follows: the ratio of the first moving speed to the pixel density of the input device is determined as the second moving speed.
[0054] The pixel density of the input device can be obtained from the physical size and resolution of the input device, for example, through the formula... Determine the pixel density of the input device, where, Characterizing the length of the input device, Characterizing the width of the input device, Characterizing the x-axis resolution of the input device, The y-axis resolution of the input device is characterized. Alternatively, the pixel density of the input device can be obtained through other means, which are not specifically limited in this disclosure.
[0055] In another embodiment of this invention, the relevant parameters of the input device may include the physical dimensions and resolution of the input device. The physical dimensions of the input device may include its length and width. Accordingly, the specific implementation for determining the second moving speed based on the first moving speed and the relevant parameters of the input device is as follows: a parameter calculation factor for the input device is determined based on its physical dimensions and resolution; the product of the first moving speed and the parameter calculation factor is then determined as the second moving speed.
[0056] For example, the parameter calculation factor for the input device is determined using the following formula:
[0057] in, The parameter calculation factor characterizing the input device Characterizing the length of the input device, Characterizing the width of the input device, Characterizing the x-axis resolution of the input device, Characterizes the y-axis resolution of the input device.
[0058] For example, suppose the first moving speed is Then it can be done through the formula , thus obtaining the second moving speed .
[0059] After obtaining the second movement speed, the third movement speed is determined based on the second movement speed and the control display gain function. Specifically, the target control display gain corresponding to the second movement speed is determined based on the second movement speed and the control display gain function, and the product of the second movement speed and the target control display gain is determined as the third movement speed.
[0060] For example, a control display gain function can be preset, and there can be one or more control display gain functions. For instance, multiple control display gain functions can be set for each gear. Figure 4 This is an exemplary embodiment illustrating the curves of the control display gain function corresponding to different gear levels. For example... Figure 4 As shown, assuming that 10 different gears can be preset with their corresponding control display gain functions, the user can select a target gear from these 10 different gears. Then, based on the second movement speed and the control display gain function corresponding to the target gear, the target control display gain corresponding to the second movement speed is determined.
[0061] exist Figure 4 In this diagram, the horizontal axis of each control display gain function curve represents the moving speed in mm / s, and the vertical axis represents the dimensionless control display gain. Therefore, after determining the control display gain function corresponding to the target gear, the vertical axis corresponding to the second moving speed can be used to determine the target control display gain for that second moving speed. Finally, the product of the second moving speed and the target control display gain is determined as the third moving speed.
[0062] After determining the third movement speed, a fourth movement speed is determined based on the third movement speed. In this disclosure, the third movement speed can be converted into a fourth movement speed based on relevant screen parameters. In one embodiment, Figure 2 Step S23, which determines the fourth movement speed based on the third movement speed, may include: obtaining relevant parameters of the screen; and determining the fourth movement speed based on the third movement speed and the relevant parameters of the screen.
[0063] The screen's parameters may include its physical size and resolution, and / or its pixel density.
[0064] In one embodiment of this example, the relevant parameters of the screen include the pixel density of the screen. Accordingly, the specific implementation of determining the fourth moving speed based on the third moving speed and the relevant parameters of the screen can be: the product of the third moving speed and the pixel density of the screen is determined as the fourth moving speed.
[0065] The pixel density of the screen can be obtained from the screen's physical size and resolution, for example, through the formula... Determine the pixel density of the screen, where, Represents the length of the screen. Characterizes the width of the screen. The x-axis resolution characterizes the screen. The y-axis resolution represents the screen. Alternatively, the screen's pixel density can be obtained through other methods, which are not specifically limited in this disclosure.
[0066] In another implementation of this embodiment, the relevant parameters of the screen include the physical size and resolution of the screen. Accordingly, the specific implementation of determining the fourth moving speed based on the third moving speed and the relevant parameters of the screen can be as follows: determine the parameter calculation factor of the screen based on the physical size and resolution of the screen; and determine the fourth moving speed as the ratio of the third moving speed to the parameter calculation factor of the screen.
[0067] For example, the screen parameter calculation factor can be determined using the following formula:
[0068] in, The parameter calculation factor characterizing the screen. Represents the length of the screen. Characterizes the width of the screen. The x-axis resolution characterizes the screen. Characterizes the screen's y-axis resolution.
[0069] For example, suppose the third moving speed is Then it can be done through the formula Result in the fourth movement speed .
[0070] Figure 5 This is a schematic diagram illustrating a pointer movement method according to an exemplary embodiment. For example... Figure 5As shown, firstly, when a user uses an input device, the input device and coprocessor MCU in the hardware layer send a data packet containing the touch position to the kernel layer via the input device driver. Next, the kernel layer reports this information to the native framework layer via the input subsystem. The native framework layer is responsible for parsing and calculating the touch control speed, i.e., the first movement speed, from the data packet. For example, the native framework layer can obtain the first movement speed based on the touch position in two adjacent received data packets and the duration of the two adjacent data receptions. The first movement speed represents the number of pixels moved corresponding to the user operation per unit time; that is, the unit of the first movement speed is pixels per second.
[0071] In one possible approach, the data packets transmitted by the kernel layer may include not only the touch point position but also relevant parameters of the input device (e.g., touchpad, graphics tablet, etc.). In this approach, the native framework layer can obtain the relevant parameters of the input device from the data packets transmitted by the kernel layer. In another possible approach, the relevant parameters of the input device can be pre-configured in the kernel layer, and when obtaining the first movement speed, the pre-configured relevant parameters of the input device can be obtained from the kernel layer.
[0072] Subsequently, the kernel layer converts the first movement speed into a second movement speed based on the relevant parameters of the input device; that is, it converts the contact control speed in pixels per second (px / s) into a contact control speed in mm / s. The specific conversion process is as described above and will not be repeated here.
[0073] Furthermore, screen-related parameters and algorithm parameters for controlling the display gain function can be pre-configured in the file system within the kernel layer. These algorithm parameters may include coefficients for the display gain function, segmentation points for the piecewise function, and thresholds for pointer display speed. The display gain function is typically a piecewise function. In this way, the native framework layer can also obtain the screen-related parameters and algorithm parameters for controlling the display gain function from the file system within the kernel layer.
[0074] Next, the algorithm parameters of the second moving speed and the control display gain function are input into the pointer acceleration algorithm in the kernel layer. The pointer acceleration algorithm determines the control display gain function based on the algorithm parameters of the control display gain function, determines the target control display gain corresponding to the second moving speed based on the control display gain function, and determines the third moving speed by multiplying the second moving speed and the target control display gain.
[0075] Next, based on the relevant parameters on the screen, the third movement speed is converted into the fourth movement speed, and the pointer speed output by the pointer acceleration algorithm, which is in mm / s, is converted into a pointer speed in px / s. Then, based on the current pointer position, the duration of receiving two adjacent data packets, and the pointer speed in px / s, the target pointer position is determined.
[0076] Finally, the native framework layer notifies the Java framework layer to draw the pointer position image. After drawing, it is submitted to the GPU (Graphics Processing Unit) for image rendering. The rendering layer composition strategy is either GPU composition or HWC (Hardware Composer) composition. The final composed image is encoded and compressed, and then driven by DSI (Display Serial Interface) to be input to the screen module for display via the MIPI protocol.
[0077] Thus, by adopting the above technical solution, it can be ensured that the input and output movement speed of the pointer acceleration algorithm are both the physical distance moved per unit time, rather than the number of pixels moved per unit time. This effectively enhances the compatibility of pointer movement across devices and improves the user's swiping responsiveness.
