Description

Technical Field

[0001] This application relates to the field of smart terminal technology, and in particular to a parameter adjustment interaction method, apparatus, terminal device, and storage medium. Background Technology

[0002] With the widespread adoption of smart devices and the continuous evolution of interactive technologies, parameter adjustment functions have become a core component of various applications and control systems, widely used in fields such as graphic design, smart home control, game operation, and industrial equipment regulation. Whether it's adjusting brush thickness and color in drawing software or controlling light brightness and color temperature in smart homes, the convenience and accuracy of parameter adjustment directly determine the user's interactive experience, and are of great significance for improving user operating efficiency and lowering the barrier to entry.

[0003] However, existing parameter adjustment interaction methods have shortcomings. Parameter adjustment is not intuitive enough. In scenarios with multiple parameters, it is necessary to switch interfaces frequently, resulting in low adjustment accuracy and efficiency. Furthermore, the interaction process lacks continuity and cannot meet users' growing demand for smooth and integrated operation.

[0004] Therefore, improving the accuracy and efficiency of parameter adjustment, facilitating multi-parameter adjustment, and enhancing the continuity of interactive adjustment operations are the technical problems that need to be solved. Summary of the Invention

[0005] This application provides a parameter adjustment interaction method, device, terminal equipment, and storage medium, which can improve the accuracy and efficiency of parameter adjustment, realize the convenience of multi-parameter adjustment, and enhance the continuity of adjustment interaction operation.

[0006] In a first aspect, embodiments of this application provide a parameter adjustment interaction method, including: In response to the user's touch operation within the fan-shaped interaction area, obtain the location information of the touch point; Based on the position information of the touch point and the geometric properties of the fan-shaped interaction area, the parameter value of the first parameter is determined; Update the display status of the first parameter based on its value; The display state of the second parameter in the user interface is updated synchronously; wherein the display state of the second parameter is associated with the parameter value of the first parameter.

[0007] In one possible implementation of the first aspect, the geometric properties of the fan-shaped interactive region include the region center point, the starting angle, and the sweeping angle; The step of determining the parameter value of the first parameter based on the position information of the touch point and the geometric properties of the fan-shaped interaction area includes: Based on the position information of the touch point and the coordinates of the center point of the area, the connecting angle is calculated. The connecting angle is the angle formed by the line connecting the touch point and the center point of the area and the preset baseline. Based on the connection angle, the starting angle, the sweep angle, and the predefined angle parameter value mapping relationship, the parameter value of the first parameter is calculated.

[0008] In one possible implementation of the first aspect, determining the parameter value of the first parameter based on the position information of the touch point and the geometric properties of the fan-shaped interaction area includes: The position information of the touch point is corrected by boundary correction to obtain the corrected position information of the touch point; The parameter value of the first parameter is determined based on the corrected position information of the touch point and the geometric properties of the fan-shaped interaction area.

[0009] In one possible implementation of the first aspect, the geometric properties of the fan-shaped interactive region include the region's center point; The step of performing boundary correction on the position information of the touch point to obtain the corrected position information of the touch point includes: Calculate the intersection point of the target ray and the boundary circle to obtain candidate intersection points. The target ray is a straight line that passes through both the center point of the region and the touch point. The boundary circle is defined by the radius of the fan-shaped interaction region. The correction position information of the touch point is determined based on the coordinates of the candidate intersection point closest to the preset reference point. The preset reference point is located on a circle with the center point of the region as the center and the radius of the preset baseline as the radius.

[0010] In one possible implementation of the first aspect, the radius of the fan-shaped interaction region includes an inner radius and an outer radius; the calculation of the intersection point of the target ray and the boundary circle includes: When the radial distance between the touch point and the center point of the region is less than the inner radius, calculate the intersection point of the target ray and the inner boundary circle defined by the inner radius; When the radial distance between the touch point and the center point of the region is greater than the outer radius, calculate the intersection point of the target ray and the outer boundary circle defined by the outer radius.

[0011] In one possible implementation of the first aspect, the method further includes: Obtain the screen size of the touch display device where the user interface is located; The geometric properties of the fan-shaped interactive area are dynamically adjusted according to the screen size.

[0012] In one possible implementation of the first aspect, the method further includes: In response to a user's action of expanding or collapsing the fan-shaped interactive area, a smooth transition animation is used to expand or collapse the fan-shaped interactive area.

[0013] Secondly, embodiments of this application provide a parameter adjustment interaction device, including: The information acquisition unit is used to acquire the position information of the touch point in response to the user's touch operation in the fan-shaped interaction area; The parameter value determination unit is used to determine the parameter value of the first parameter based on the position information of the touch point and the geometric properties of the fan-shaped interaction area. An adjustment interaction unit is used to update the display state of the first parameter according to the parameter value of the first parameter; and synchronously update the display state of the second parameter in the user interface; wherein the display state of the second parameter is associated with the parameter value of the first parameter.

[0014] Thirdly, embodiments of this application provide a terminal device, including a memory, a processor, and a computer program stored in the memory and executable on the processor. When the processor executes the computer program, it implements the parameter adjustment interaction method as described in the first aspect above.

[0015] Fourthly, embodiments of this application provide a computer-readable storage medium storing a computer program that, when executed by a processor, implements the parameter adjustment interaction method as described in the first aspect above.

[0016] Fifthly, embodiments of this application provide a computer program product that, when run on a terminal device, causes the terminal device to execute the parameter adjustment interaction method described in the first aspect above.

[0017] In this embodiment, the terminal device responds to the user's touch operation within the fan-shaped interactive area, obtains the position information of the touch point. Since the specific geometric features of the fan-shaped interactive area are more compatible with the user's spatial cognition, it can provide an intuitive and accurate operational basis for parameter adjustment, thereby improving the intuitiveness of the interaction. Then, based on the position information of the touch point and the geometric attributes of the fan-shaped interactive area, the parameter value of the first parameter is determined. By accurately mapping the touch position to the parameter space defined by the fan-shaped geometry, a direct and continuous mapping between the touch operation and the parameter value is achieved, avoiding the problem of fuzzy parameter correspondence in traditional linear adjustment. This can significantly improve the accuracy of parameter adjustment, while simplifying the calculation process of parameter values ​​and further improving adjustment efficiency. Then, the display state of the first parameter is updated according to its parameter value, and the display state of the associated second parameter is updated synchronously. Multi-parameter linkage adjustment can be completed without the user manually switching the interface. This not only eliminates the tedious steps of frequently switching the operation interface in traditional multi-parameter adjustment, achieving the convenience of multi-parameter adjustment, but also avoids the interruption of the operation process, effectively enhancing the continuity of the adjustment interaction operation.

Detailed Implementation

[0020] In the following description, specific details such as particular system architectures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of this application. However, those skilled in the art will understand that this application may also be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods have been omitted so as not to obscure the description of this application with unnecessary detail.

[0021] It should be understood that, when used in this application specification and the appended claims, the term "comprising" indicates the presence of the described features, integrals, steps, operations, elements and / or components, but does not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components and / or a collection thereof.

[0022] It should also be understood that the term “and / or” as used in this application specification and the appended claims means any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0023] As used in this application specification and the appended claims, the term "if" may be interpreted, depending on the context, as "when," "once," "in response to determination," or "in response to detection." Similarly, the phrase "if determined" or "if detected [the described condition or event]" may be interpreted, depending on the context, as meaning "once determined," "in response to determination," "once detected [the described condition or event]," or "in response to detection [the described condition or event]."

[0024] Furthermore, in the description of this application and the appended claims, the terms "first," "second," "third," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0025] References to "one embodiment" or "some embodiments" as described in this specification mean that one or more embodiments of this application include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. The terms "comprising," "including," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.

[0026] Existing parameter adjustment interaction methods still have significant shortcomings: while linear slider adjustment is simple in structure, the adjustment logic for some parameters does not align with the user's spatial perception, making parameter adjustment less intuitive and prone to accuracy deviations when adjusting within a small range; ordinary circular adjustment controls typically only control a single parameter, failing to meet the needs of multi-parameter collaborative adjustment; independent panel-style adjustment solutions scatter multiple parameters, requiring users to frequently switch interfaces when adjusting different parameters, interrupting the operation flow. In multi-parameter adjustment scenarios, these methods result in cumbersome operation steps, low adjustment accuracy and efficiency, and a lack of continuity in the interaction process, failing to meet users' growing demand for smooth and integrated operation. In view of this, embodiments of this application provide a parameter adjustment interaction method, which aims to improve the accuracy and efficiency of parameter adjustment, realize the convenience of multi-parameter adjustment, and enhance the coherence of adjustment interaction operation.

[0027] By way of example and not limitation, the parameter adjustment interaction method provided in this application is applicable to various types of terminal devices that require parameter adjustment interaction. Specific terminal devices may include mobile phones, tablets, wearable devices, laptops, ultra-mobile personal computers (UMPCs), desktop computers, interactive large screens, and servers, etc. This application does not impose any restrictions on the specific type of terminal device.

[0028] Figure 1 The implementation flow of the parameter adjustment interaction method provided in this application embodiment is illustrated. The method flow includes steps S101 to S104. The specific implementation principle of each step is as follows: Step S101: In response to the user's touch operation within the fan-shaped interaction area, obtain the position information of the touch point.

[0029] A touch operation is generated when a user's finger or stylus touches, clicks, or swipes within the fan-shaped interactive area of ​​a touch display device. This touch display device is a terminal device that integrates touch interaction and display functions. The touch display device accurately identifies this touch operation through underlying hardware drivers and event listening mechanisms. Once a touch operation is identified, the location information of the touch point is obtained. This location information includes the coordinates of the touch point in the screen's global coordinate system. These coordinates are in pixels, for example, they can be represented as (X, Y). The touch point's location information precisely records the relative position of the touch point to the edge of the screen when the touch operation occurs.

[0030] In this embodiment, the interactive area responding to user touch operations is a fan-shaped interactive area. This fan-shaped interactive area is not a complete circle, but rather a ring-shaped partial area displayed on the user interface. The shape and extent of the fan-shaped interactive area are defined by its geometric properties. This fan-shaped interactive area serves as a graphical control on the user interface, providing the user with a visual operation plane for parameter adjustment.

[0031] In one possible implementation, the geometric attributes of the fan-shaped interactive area include the area center point, inner radius, outer radius, starting angle, and sweep angle. The area center point is the reference point defining the geometry of the fan-shaped interactive area; both the inner and outer radii are centered on the area center point. The inner radius is the radius length of the fan shape closer to the area center point, and the outer radius is the radius length of the fan shape farther from the area center point, with the outer radius being larger than the inner radius. The inner radius is used to define the inner boundary, and the outer radius is used to define the outer boundary. Together, the inner and outer radii define a ring-shaped, wide touch band on the screen, providing the user with a clear touch interactive area with a certain margin of error, avoiding misjudging the touch point as being in the center or too far away; the starting angle defines the angular starting boundary of the fan-shaped interactive area; the sweep angle is the extent to which the fan-shaped interactive area expands from the starting angle, defining the angular range covered by the fan-shaped interactive area from the starting boundary, with the sweep angle value ranging from greater than 0° to less than 360°.

[0032] For example, if the starting angle is 0 degrees horizontally to the right, the sweeping angle is 270 degrees horizontally to the right, the inner radius is 20 pixels, and the outer radius is 100 pixels, then this fan-shaped interaction area is a specific fan-shaped area that starts from the right, covers a 270-degree range clockwise, and has inner and outer boundaries 20 pixels and 100 pixels away from the center point, respectively. Figure 1.1 As shown, this annular fan-shaped area serves as a dedicated control on the user interface, providing users with a visual operation plane for parameter adjustment.

[0033] In this embodiment, a fan-shaped interactive area, a specific graphical control, provides a clear, intuitive, and spatially oriented input interface for users to adjust parameters. This fan-shaped interactive area accurately converts user touch operations into positional information that the terminal device can process, laying an intuitive, efficient, and error-prone foundation from the source of the interaction, thus helping to improve the reliability of parameter adjustment interaction.

[0034] As one possible implementation of this application Figure 2 This paper illustrates a specific implementation process for adjusting the geometric properties of a fan-shaped interactive area in the parameter adjustment interaction method provided in an embodiment of this application, detailed below: A1: Obtain the screen size of the touch display device where the user interface is located.

[0035] Screen size is a key dimensional parameter of touch display devices. The screen size can be read directly through the touch display device's API, ensuring the accuracy and real-time nature of the data acquisition.

[0036] In one possible implementation, the screen size includes both physical size and pixel size, which together determine the adaptation benchmark for the fan-shaped interactive area. The physical size is measured in inches and reflects the actual size of the screen, such as a 6.7-inch smartphone, a 10.1-inch touchscreen drawing tablet, etc. The pixel size is measured in pixels and reflects the display resolution of the screen. The pixel size includes the number of horizontal pixels and the number of vertical pixels on the screen, such as 2400×1080, 2560×1600, etc.

[0037] In one possible implementation, the screen size is the actual display size after removing the screen notch and bezels. The process of obtaining the screen size needs to exclude the influence of non-display areas such as the screen notch and bezels, and only collect the size data of the effective display area.

[0038] A2: Dynamically adjust the geometric properties of the fan-shaped interactive area according to the screen size.

[0039] For touch display devices with different screen sizes, the geometric properties of the fan-shaped interaction area are dynamically adjusted according to the preset adaptation rules. This mainly involves adjusting the inner radius, outer radius, and sweep angle of the fan-shaped interaction area to adapt it to the touch display device.

[0040] In one possible implementation, the inner and outer radii of the fan-shaped interactive area are dynamically adjusted using a fixed ratio of the screen size as a calculation benchmark. For example, the outer radius is made to have a first preset ratio with the screen width, and the inner radius is made to have a second preset ratio with the outer radius, meaning the inner radius adjusts in tandem with the outer radius. The center point of the fan-shaped interactive area is automatically determined based on the screen size and a preset interface margin, which is a device-defined safe distance from the screen edge. For example, the center point is placed at a fixed offset from the lower right corner of the screen. The starting angle and sweeping angle of the fan-shaped interactive area are preset to fixed values ​​according to the user interface layout scheme. Alternatively, the starting angle of the fan-shaped interactive area is preset to a fixed value according to the user interface layout scheme, and the sweeping angle is dynamically fine-tuned within a certain preset range based on the screen aspect ratio, thereby ensuring that the fan-shaped interactive area maintains operational usability under specific screen ratios.

[0041] In this embodiment, by obtaining the screen size of the touch display device where the user interface is located, and dynamically adjusting the geometric properties of the fan-shaped interaction area based on the screen size, it is ensured that the fan-shaped interaction area and even the entire parameter adjustment interface can intelligently adapt to various touch display devices of different sizes, such as mobile phones, tablets and large touch screens. This enhances the device adaptability and versatility of the parameter adjustment interaction method, ensuring that users can obtain an intuitive, comfortable and consistent operating experience on different hardware platforms.

[0042] In one possible implementation, in response to a user's operation to expand or collapse the fan-shaped interactive area, a smooth transition animation is used to expand or collapse the fan-shaped interactive area.

[0043] The expand or collapse trigger action is a predefined, specific command executed by the user to bring up or hide the fan-shaped interactive area, distinct from regular parameter adjustment touch operations. The specific form of this expand or collapse trigger action can be customized according to the application scenario. For example, in a drawing scenario, the fan-shaped interactive area can be expanded or collapsed by long-pressing a specific area of ​​the canvas, double-clicking a tool icon, or swiping a specific distance inward from the edge of the screen.

[0044] In one possible implementation, smooth transition animation includes any one of Bézier curve-based animation, linear interpolation animation, or physical spring animation.

[0045] In this embodiment, a smooth transition animation is used during the expansion or collapse of the fan-shaped interactive area, so that the fan-shaped interactive area naturally and continuously changes from one visual state (such as completely hidden or completely expanded) to another visual state (such as completely expanded or completely collapsed), avoiding instantaneous changes in the user interface, making the overall interaction process more coherent and enhancing the user experience.

[0046] Step S102: Determine the parameter value of the first parameter based on the position information of the touch point and the geometric properties of the fan-shaped interaction area.

[0047] The first parameter is the target parameter that the user directly adjusts during this touch operation. The type and value range of the first parameter are preset according to the specific application scenario.

[0048] In one possible implementation, in a painting scenario, the first parameter includes brush thickness, brush color hue, etc.; in a smart home scenario, the first parameter includes light brightness, light color temperature, etc.; in an industrial control scenario, the first parameter includes equipment operating parameters, etc.; and in a gaming scenario, the first parameter includes character skill parameters, etc.

[0049] In one possible implementation, the value range of the first parameter is set in the form of a range of "minimum value - maximum value". For example, the value range of brush thickness is 3 pixels to 30 pixels; the value range of light brightness is 10% to 100%.

[0050] As one possible implementation of this application, the geometric properties of the fan-shaped interactive area include the area center point, the starting angle, and the sweeping angle; Figure 3 A specific implementation flow of step S102 in the parameter adjustment interaction method provided in the embodiment of this application is shown below: B1: Calculate the connecting angle based on the position information of the touch point and the coordinates of the center point of the area. The connecting angle is the angle formed by the line connecting the touch point and the center point of the area and a preset baseline.

[0051] The preset baseline is a directional reference standard for calculating the connection angle; it is a pre-set reference line used to measure the direction of the connection. In one possible implementation, to ensure intuitive operation and versatility, the horizontal rightward direction of the screen is set as the preset baseline (corresponding to the 0° starting angle direction).

[0052] In one possible implementation, the position information of the touch point includes the coordinates (x, y) of the touch point. The difference between the coordinates (x, y) of the touch point and the coordinates (x0, y0) of the center point of the area is calculated to obtain the relative coordinates (dx, dy), where dx = x - x0 (lateral difference) and dy = y - y0 (vertical difference). The initial angle is calculated using the arctangent function arctan2(dy, dx). This arctangent function can directly determine the quadrant of the angle based on the signs of dx and dy, avoiding the quadrant determination error of a single arctangent function. According to the conversion formula: The initial radian value of the included angle is converted into an angle value. After adjusting the angle value to a standard range of 0°-360°, the angle between the touch point and the center point of the area is obtained. For example, when the calculated angle is -45°, it is adjusted to 315°. By accurately calculating the coordinate difference and the arctangent function, the dimensional difference of the touch point position information is eliminated. With the quadrant recognition capability of the arctan2 function and the standard range adjustment of 0°-360°, parameter adjustment gaps caused by deviations in the calculation of the connecting angle are avoided, which helps to improve the accuracy of parameter adjustment.

[0053] This embodiment converts touch operations into angle data, which conforms to the geometric characteristics of the fan-shaped interaction area and the user's spatial cognition habits. For example, the angle increases when sliding clockwise, laying the foundation for the intuitiveness of subsequent parameter adjustments.

[0054] B2: Based on the connection angle, the starting angle, the sweep angle, and the predefined angle parameter value mapping relationship, the parameter value of the first parameter is calculated.

[0055] The starting angle determines the initial position of the fan-shaped interactive area, while the sweep angle determines the effective angle range of the fan-shaped interactive area. Together, they define the effective angle range for mapping the connecting angle to the parameter value, thus ensuring that only touch operations within the fan-shaped interactive area trigger parameter value calculations. The predefined angle parameter value mapping relationship includes the mapping relationship between the connecting angle and the first parameter value. This is a pre-set logical rule or mathematical model stored in the touch display device, used to establish the correspondence between the connecting angle and the parameter value of the first parameter. This mapping relationship defines how to map connecting angle values ​​falling within the effective angle range to the value range of the first parameter.

[0056] The predefined angle parameter value mapping relationship can adopt a linear mapping model, or, depending on the parameter type and requirements, a piecewise mapping, nonlinear mapping, or other models. The mapping relationship is implemented in the form of formulas or data mapping tables. This predefined angle parameter value mapping relationship can be configured according to different application scenarios.

[0057] In one possible implementation, the predefined angle parameter value mapping relationship adopts a linear mapping model, as shown in the following formula (1): (1) Wherein, minVal represents the minimum value of the first parameter, maxVal represents the maximum value of the first parameter, θ represents the connection angle, θs represents the starting angle, and θw represents the sweep angle. The minimum and maximum values ​​of the first parameter are preset parameter range boundary values ​​based on the application scenario, for example, a brush thickness of 3 pixels to 30 pixels; the difference between the connection angle and the starting angle is used to determine the relative angular position of the touch point within the fan-shaped interaction area.

[0058] In this embodiment, a predefined linear mapping relationship is established to create an intuitive correspondence between angle data and parameter values. This ensures that the user's touch operation is consistent with the parameter change logic. Even minute changes in the user's touch operation on the fan-shaped interaction area can be perceived and translated into subtle changes in parameter values. This mapping mechanism fundamentally guarantees high precision in parameter adjustment and overcomes the precision loss problem caused by the mismatch between the physical movement distance and the parameter change ratio when adjusting a traditional slider within a small range. Furthermore, since the entire mapping process is based on the intuitive geometric relationship between angles and the fan shape, it greatly enhances the intuitiveness of the adjustment operation, improves the overall adjustment efficiency, and effectively enhances the user's interactive experience.

[0059] As one possible implementation of this application Figure 4 Another specific implementation flow of step S102 in the parameter adjustment interaction method provided in the embodiment of this application is shown below: C1: Perform boundary correction on the position information of the touch point to obtain the corrected position information of the touch point.

[0060] When a user performs a touch operation on a touch display device, the touch point may not fall precisely within the effective boundary of the predetermined fan-shaped interaction area. It may slightly exceed the outer boundary or intrude into the area within the inner boundary. Boundary correction, through preset correction rules, adjusts the position information of touch points that deviate from the effective interaction range of the fan-shaped interaction area to a reasonable position within the effective interaction range, while simultaneously smoothing and correcting offset data close to the boundary. The corrected position information is the position information of the touch point that is completely within the effective interaction range of the fan-shaped interaction area after boundary correction.

[0061] C2: Determine the parameter value of the first parameter based on the corrected position information of the touch point and the geometric properties of the fan-shaped interaction area.

[0062] Based on the corrected position information after boundary correction and the geometric properties of the sector interaction area, the specific process of determining the parameter value of the first parameter can be referred to the relevant content of steps B1-B2 above, which will not be repeated here.

[0063] In this embodiment, by performing boundary correction on the position information of the touch point, the problems of edge calculation error and poor operation fault tolerance that may be caused by the original touch position information are solved. This can enhance the fault tolerance and user-friendliness of parameter adjustment interaction. Users can obtain the expected and accurate parameter adjustment results without performing extremely precise touch point control. This makes parameter adjustment both meet the convenience needs of ordinary users and adapt to the high precision requirements of professional scenarios.

[0064] As one possible implementation of this application Figure 5This paper illustrates a specific implementation process for boundary correction of the position information of touch points in the parameter adjustment interaction method provided in this application embodiment, which is described in detail below: D1: Calculate the intersection points of the target ray and the boundary circle to obtain candidate intersection points. The target ray is a straight line passing through both the center point of the region and the touch point, and the boundary circle is defined by the radius of the sector-shaped interaction region. There are two candidate intersection points.

[0065] In this embodiment, the target ray is a straight line that starts from the center point of the fan-shaped interaction area and extends infinitely through the original touch point. It describes the absolute direction of the touch point relative to the center point of the area.

[0066] The boundary circle is a virtual circle with the center point of the region as its center and the radius of the fan-shaped interactive area as its radius.

[0067] D2: Determine the correction position information of the touch point based on the coordinates of the candidate intersection point closest to the preset reference point. The preset reference point is located on a circle with the center point of the region as the center and the radius of the preset baseline as the radius.

[0068] The preset reference point is a predefined benchmark point used for distance comparison. The angle between the preset reference point and the center point of the area is the angle between the target ray and the preset baseline, and it is aligned with the current touch operation direction. Geometrically, the preset reference point is a point on the circumference of a circle centered at the center point of the area and with the preset baseline radius as its radius, perfectly aligned with the current touch operation direction.

[0069] The preset baseline radius is a predefined constant value. In one possible implementation, the preset baseline radius can be the average of the inner and outer radii of the fan-shaped interaction area, in which the preset reference point is located on the central track of the fan-shaped interaction area.

[0070] In one possible implementation, the intersection point is calculated through the following analytical geometric process: Let the coordinates of the center of the baseline circle (i.e. the center point of the region) be (xA, yA) and its radius be rA (the preset baseline radius); let the coordinates of the center of the boundary circle be (xB, yB) and its radius be rB; let the angle of the line be θ (i.e. the angle formed by the target ray and the preset baseline).

[0071] The mathematical expression of the target ray is the equation of a straight line passing through the center point of the region and the touch point, which is given by the following formula (2): (2) Where t represents the displacement factor.

[0072] Substituting the equation of the target ray into the equation of the boundary circle B, we get the following formula (3): (3) After simplification and solution, a quadratic equation in terms of the displacement factor t is obtained, as shown in formula (4): (4) in, ; .

[0073] Solve the quadratic equation (4) and calculate the discriminant. We obtain two solutions for the displacement factor t: .

[0074] t1 and t2 correspond to the coordinates of two candidate intersection points (x1, y1) and (x2, y2) of the straight line and the boundary circle, respectively. Calculate the distances between (x1, y1) and (x2, y2) and the preset reference point P(xA+rAcosθ, yA+rAsinθ). Select the candidate intersection point closest to the preset reference point from these two candidate intersection points, and determine the correction position information of the touch point based on the coordinates of the closest candidate intersection point.

[0075] In this embodiment of the application, the intention of correcting the touch point to the boundary is transformed into a mathematical problem of solving the coordinates of the specific intersection point by means of analytical geometry, thereby laying the foundation for obtaining accurate touch point position information.

[0076] As one possible implementation of this application, the radius of the fan-shaped interaction area includes an inner radius and an outer radius; Figure 6 The following is a detailed implementation process of calculating the intersection point of the target ray and the boundary circle in the parameter adjustment interaction method provided in this application embodiment: D11: When the radial distance between the touch point and the center point of the region is less than the inner radius, calculate the intersection point of the target ray and the inner boundary circle defined by the inner radius.

[0077] D12: When the radial distance between the touch point and the center point of the region is greater than the outer radius, calculate the intersection point of the target ray and the outer boundary circle defined by the outer radius.

[0078] Radial distance refers to the straight-line distance between the touch point and the center point of the area within the screen plane. The inner boundary circle is a virtual circle constructed with the area's center as the center and its inner radius as the radius. It represents the inner boundary of the effective interaction range of the fan-shaped interaction area; this inner boundary is the boundary of the fan-shaped interaction area closer to the area's center. The outer boundary circle is a virtual circle constructed with the area's center as the center and its outer radius as the radius. It represents the outer boundary of the effective interaction range of the fan-shaped interaction area; this outer boundary is the boundary of the fan-shaped interaction area farther from the area's center. The inner and outer boundaries together define the effective interaction range of the fan-shaped interaction area.

[0079] When the radial distance between the touch point and the center point of the area is less than the inner radius, the user's touch point is too close to the center point of the area and falls into the inner circular blank area of ​​the fan-shaped interaction area. This circular blank area is an invalid area. At this time, it is necessary to calculate the intersection of the target ray and the inner boundary circle as the correction benchmark to correct the touch point to the effective interaction range.

[0080] When the radial distance between the touch point and the center point of the area is less than the inner radius, the user touch point is too far away from the center point of the area and exceeds the outer boundary of the fan-shaped interaction area. In this case, it is necessary to calculate the intersection of the target ray and the outer boundary circle as the correction benchmark to correct the touch point to the effective interaction range.

[0081] This application embodiment automatically triggers a correction process for the inner and outer boundaries by determining the radial distance. This ensures that touch operations that deviate inward can be accurately corrected to the inner boundary, and touch operations that deviate outward can be accurately corrected to the outer boundary. This effectively avoids the mismatch of parameter value calculation areas that may be caused by the touch point being too close to the center, and the input failure that may be caused by the touch point exceeding the effective interaction range, thus ensuring the effectiveness of the interaction.

[0082] Step S103: Update the display status of the first parameter according to the parameter value of the first parameter.

[0083] Display status refers to the visual presentation of parameters in the user interface. Based on the value of the first parameter, its display status is updated to present the adjusted parameter value to the user in an intuitive way, ensuring that the user can perceive the adjustment effect in real time.

[0084] In one possible implementation, the visual presentation of the displayed status includes, but is not limited to, progress indicator elements (such as curved progress bars, circular indicators), numerical display boxes, and icon status changes. The progress indicator element can dynamically provide visual feedback on the relative position of the current value of the first parameter within its entire adjustable range. When the parameter value changes, the fill length of the curved progress bar or the indication position of the circular indicator will be updated accordingly, making the parameter status immediately clear. The specific visual presentation of the progress indicator element can be configured according to the application scenario and user needs.

[0085] For example, if the first parameter is brush transparency, its value range is [0%, 100%]. After calculating the transparency value to be 65% in step S102, the value next to the transparency label in the user interface is immediately updated to 65%, and the corresponding arc-shaped progress bar is filled from the starting point of 0% to the position of 65%. This arc-shaped progress bar visually displays the continuous change range of the parameter from 0% to 100%, realizing the real-time update of the parameter display status.

[0086] In this embodiment, by updating the display status of the first parameter in real time, the user is provided with immediate and intuitive adjustment feedback, enabling the user to quickly confirm whether the current parameter value meets the requirements, avoiding repeated adjustments or adjustment deviations caused by feedback delays, reducing invalid operations, and further improving the efficiency and accuracy of parameter adjustment.

[0087] Step S104: Synchronously update the display state of the second parameter in the user interface; wherein the display state of the second parameter is associated with the parameter value of the first parameter.

[0088] The second parameter is another parameter that has a preset relationship with the first parameter. The display state of the second parameter will change synchronously with the change of the parameter value of the first parameter. There can be one or more second parameters.

[0089] Synchronous update refers to automatically triggering an update of at least one second parameter's display status while updating the first parameter's display status, or within a very short timeframe that the user cannot perceive the delay, without requiring the user to perform any additional interface switching, mode switching, or confirmation operations.

[0090] In one possible implementation, the relationship between the first parameter and the second parameter can be preset according to the actual needs of the application scenario. For example, in a color adjustment scenario in the HSV color space, the first parameter is hue, and the second parameter can be saturation; in an air conditioning control scenario, the first parameter is temperature, and the second parameter can be fan speed.

[0091] The visual presentation of the second parameter in the user interface can be dynamically calculated and refreshed in real time based on the current value of the first parameter. In one possible implementation, a parameter association mapping table is pre-established. Once the value of the first parameter is determined, the corresponding parameter value of the second parameter is determined based on the parameter association mapping table, and the display state of the second parameter is updated based on the determined parameter value.

[0092] In this embodiment, the collaborative adjustment of multiple parameters within the same user interface is achieved through the correlation mechanism and synchronous update logic between parameters, which completely solves the problem of frequent interface switching required for multi-parameter adjustment in traditional solutions, enhances the continuity of operation, significantly reduces the user's operating costs and memory burden, and greatly improves the convenience of multi-parameter adjustment.

[0093] As can be seen from the above, in this embodiment, the terminal device responds to the user's touch operation within the fan-shaped interactive area and obtains the position information of the touch point. Since the specific geometric features of the fan-shaped interactive area are more compatible with the user's spatial cognition, it can provide an intuitive and accurate operational basis for parameter adjustment, thereby improving the intuitiveness of the interaction. Then, based on the position information of the touch point and the geometric attributes of the fan-shaped interactive area, the parameter value of the first parameter is determined. By accurately mapping the touch position to the parameter space defined by the fan-shaped geometry, a direct and continuous mapping between the touch operation and the parameter value is achieved, avoiding the problem of fuzzy parameter correspondence in traditional linear adjustment. This can significantly improve the accuracy of parameter adjustment, while simplifying the calculation process of parameter values ​​and further improving adjustment efficiency. Then, the display state of the first parameter is updated according to its parameter value, and the display state of the associated second parameter is updated synchronously. Multi-parameter linkage adjustment can be completed without the user manually switching the interface. This not only eliminates the tedious steps of frequently switching the operation interface in traditional multi-parameter adjustment, but also achieves the convenience of multi-parameter adjustment and avoids the interruption of the operation process, effectively enhancing the continuity of the adjustment interaction operation.

The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of this application.

[0103] As can be seen from the above, in this embodiment, the terminal device responds to the user's touch operation within the fan-shaped interactive area and obtains the position information of the touch point. Since the specific geometric features of the fan-shaped interactive area are more compatible with the user's spatial cognition, it can provide an intuitive and accurate operational basis for parameter adjustment, thereby improving the intuitiveness of the interaction.
