Description

Technical Field

[0001] This invention relates to the field of multimedia technology, and in particular to a method, apparatus, storage medium, and interactive flat panel for dynamically adjusting touch resolution. Background Technology

[0002] Touchscreen technology is a new type of human-computer interaction input method. Compared with traditional keyboard and mouse input methods, touchscreen input is more intuitive. With the development of touchscreen technology, touchscreens are increasingly being used in electronic products such as smart tablets and laptops. A touchscreen typically consists of multiple touch points arranged in an array. The number of touch points is fixed after the touchscreen is manufactured. During use, some touch points can be controlled to respond to the user's touch operations and generate touch data, thereby locating the user's touch position. These touch points that can respond to the user's touch operations and generate touch data are called touch detection points. Generally, touch resolution is used to represent the number of touch detection points on a touchscreen.

[0003] In the process of developing this invention, the inventors discovered that while high touch resolution can achieve high touch accuracy, it also means a large volume of touch data is collected. Since the data transmission rate is fixed, sending such large amounts of touch data to the touchscreen's data processing system results in significant touch latency. Conversely, low touch resolution means a smaller volume of touch data is collected, achieving low touch latency, but this reduces the number of touch points, leading to lower touch accuracy. In applications where writing is performed on a touchscreen, high touch resolution is required for precise writing; if the current touchscreen resolution is lower than a high touch resolution, the user's touch accuracy requirements cannot be met. Conversely, in applications where application settings are performed on a touchscreen, low touch resolution is required for low touch latency; if the current touchscreen resolution is higher than a low touch resolution, latency is increased.

[0030] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims. In the description of this application, it should be understood that the terms "first," "second," "third," etc., are used only to distinguish similar objects and are not necessarily used to describe a specific order or sequence, nor should they be construed as indicating or implying relative importance. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0034] Furthermore, in the description of this application, unless otherwise stated, "multiple" means two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone. The character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0035] The touch resolution dynamic adjustment method provided in this embodiment can be executed by a touch resolution dynamic adjustment device. This device can be implemented through software and / or hardware, and can consist of two or more physical entities, or a single physical entity. The touch resolution dynamic adjustment device can be any electronic device with data processing software installed, such as a computer, mobile phone, tablet, or interactive whiteboard, or other smart device.

[0036] For ease of understanding, the embodiments use an interactive flat panel as an example to illustrate dynamically adjustable touch resolution. The interactive flat panel can be an integrated device that uses touch technology to control content displayed on a flat panel and achieve human-computer interaction. It integrates one or more functions such as a projector, electronic whiteboard, screen, audio system, television, and video conferencing terminal.

[0037] Generally, an interactive flat panel includes at least one display screen. For example, an interactive flat panel may have a touch-enabled display screen, which can be resistive, capacitive, infrared, electromagnetic, or surface acoustic wave (SAW) type. In one embodiment, a user can perform touch operations by touching the display screen with their finger or a stylus. The interactive flat panel detects the touch location and determines a response scheme based on the corresponding display content, thus implementing the touch function. For example, if the touch location indicates that the corresponding display content is a control for a specific function, the response scheme is to execute that function. It is understood that in practical applications, users can also perform control operations using a keyboard, mouse, physical buttons, etc.

[0038] Typically, an interactive flat panel is equipped with at least one operating system, including but not limited to Android, Linux, and Windows. In one embodiment, the interactive flat panel can install at least one application based on the operating system; for example, it may have an electronic whiteboard application with drawing capabilities. This application can be a built-in application of the operating system or an application downloaded from a third-party device or server. The touch data compression device can also be the application itself. Optionally, in addition to drawing capabilities, the application may also have other editing functions, such as writing, inserting tables, inserting images, inserting multimedia, inserting graphics, and drawing tables.

[0039] The interactive flat panel may include one or more processing cores, which can implement the touch data compression method of this application through pure software or through a combination of software and hardware. For example, it can be implemented using at least one hardware form selected from digital signal processing, field-programmable gate arrays, and programmable logic arrays. It can integrate one or more of the following: a central processing unit, an image processor, and a modem. The interactive flat panel can run an application for the touch data compression method. The application can be presented in a form adapted to the interactive flat panel, such as an APP application. In some examples, it can also be presented in the form of, for example, a system plugin or a web page plugin.

[0040] Example 1

[0041] To better understand the technical solution of this application, the touch resolution is described below.

[0042] Interactive flat panels typically include multiple touch points arranged in an array. The number of touch points is fixed after the interactive flat panel is manufactured. When the display screen on the interactive flat panel is an infrared touchscreen, infrared emitters and receivers are installed on opposite sides of the infrared touchscreen in the X and Y directions, respectively, to emit and receive detection light. The intersection of the detection light rays in the X and Y directions is the touch point. For example, if the number of infrared emitters in the X and Y directions of the infrared touchscreen is 1920 and 1080 respectively, then the number of touch points on the infrared touchscreen is 1920. 1080.

[0043] In the use of an infrared touchscreen, some touch points can be controlled to generate touch data in response to the user's touch operation, thereby locating the user's touch position. These touch points that generate touch data in response to the user's touch operation are called touch detection points, and touch resolution indicates the number of touch detection points on the touchscreen. A higher touch resolution results in more touch detection points, and vice versa. For example, if the number of infrared emitters in the X and Y directions of an infrared touchscreen is 1920 and 1080 respectively, then the number of touch points on the infrared touchscreen is 1920. 1080, at this point, the touch resolution of the infrared touchscreen is 1920. 1080; however, by controlling the infrared touchscreen to perform interlaced scanning in the X direction, the number of touch detection points on the infrared touchscreen becomes 960. 1080, at this point, the touch resolution of the infrared touchscreen is 960. 1080. Similarly, the infrared touchscreen can be controlled to perform interlaced scanning in the Y direction, thereby changing the number of detection points of the infrared touchscreen to 1920. 540, touch resolution is 1920 540.

[0044] Similarly, when the display on the interactive flat panel is a capacitive touchscreen or other touchscreen, the touch resolution can be adjusted by controlling some touch points to respond to the user's touch operation and generate touch data.

[0045] For example, when the display screen on an interactive flat panel is a capacitive touchscreen, it typically has M+N physical capacitive touch sensors. These M+N interleaved sensors form M×N capacitive sensing points. When a user's finger approaches the touchscreen, the capacitance value of these sensing points changes accordingly. By controlling some of these sensing points to respond to the user's touch operation and generate touch data, the user's touch position can be located. These capacitive sensing points that generate touch data in response to the user's touch operation are called touch detection points, and touch resolution indicates the number of touch detection points on the capacitive touchscreen. A higher touch resolution indicates a larger number of touch detection points, and vice versa.

[0046] For example, when the display on an interactive flat panel is a resistive touchscreen, the resistive touchscreen has a structure of a thin film plus glass, with an ITO conductive coating on the adjacent surfaces of the film and glass. When a user touches the resistive touchscreen, the two mutually insulated ITO conductive coatings make contact at the touch point. A corresponding electrical signal is transmitted via a sensor, which can control some touch points to respond to the user's touch operation and generate touch data, thereby locating the user's touch position. The touch points that generate touch data in response to the user's touch operation are called touch detection points, and the touch resolution indicates the number of touch detection points on the resistive touchscreen. A higher touch resolution means more touch detection points, and vice versa.

[0047] Please see Figure 1 This is a flowchart illustrating a method for dynamically adjusting touch resolution according to an embodiment of this application. The method for dynamically adjusting touch resolution according to an embodiment of this application includes the following steps:

[0048] S10. When the touch operation on the touch screen meets the preset conditions, obtain the current application scenario identifier of the touch screen and the current display resolution of the touch screen.

[0049] When a touch operation on the touchscreen meets preset conditions, it can open a preset application or a preset control. The application scenario identifier is used to identify and mark the application scenario and can be a number, letter, or other identifier. The application scenario is launching a preset application on the touchscreen or launching a preset control within that application. Display resolution is the resolution of the display screen when displaying images; specifically, display resolution refers to the number of horizontal and vertical pixels across the entire visible area of ​​the display screen. In this embodiment, when a user performs a touch operation on the touchscreen, and the touch operation meets preset conditions, the user enters a specific application scenario, and the application scenario identifier and current display resolution corresponding to the current application scenario are obtained.

[0050] S20. Based on the preset mapping relationship between application scenario identifiers and touch coefficients, obtain the touch coefficient corresponding to the current application scenario identifier.

[0051] Touch coefficient is an indicator used to measure touch resolution. Generally, higher touch resolution corresponds to a larger touch coefficient, and lower touch resolution corresponds to a smaller touch coefficient. In the preset mapping relationship between application scenario identifiers and touch coefficients, each application scenario identifier corresponds to a unique touch coefficient. In this embodiment, the preset mapping relationship between application scenario identifiers and touch coefficients is created as a mapping table. For example, application scenario identifier k1 corresponds to touch coefficient e1, application scenario identifier k2 corresponds to touch coefficient e2, and so on. After obtaining the current application scenario identifier, the mapping table is searched based on the application scenario identifier to obtain the touch coefficient corresponding to the current application scenario identifier.

[0052] S30. Obtain the target touch resolution based on the display resolution and the touch coefficient.

[0053] Since each pixel touched by a user corresponds to one or more touch detection points, the target touch resolution of the touchscreen can be obtained based on the current display resolution and touch coefficient of the touchscreen.

[0054] S40. Adjust the touch resolution of the touch screen to the target touch resolution to detect touch operations on the touch screen according to the target touch resolution; wherein, the touch resolution is the number of touch detection points within the touch screen used to respond to touch operations.

[0055] In touchscreen writing applications, the writing process involves adjusting the thickness of the handwriting and recognizing the strokes of the characters, thus requiring a large number of touch detection points, i.e., setting a high touch resolution to achieve fine writing. In touchscreen application settings, which involve enabling and disabling multiple application options, rapid response is required, i.e., setting a low touch resolution to achieve low touch latency. In this embodiment, after obtaining the target touch resolution corresponding to different application scenarios, the touch resolution of the touchscreen is adjusted to the target touch resolution to detect touch operations on the touchscreen according to the target touch resolution. For example, the touch resolution of the touchscreen is 1920. 1080p, target touch resolution is 480p. 270, the number of touch detection points that will generate touch data is increased from 1920. 1080 adjusted to 480 270. Touch operations on the touchscreen are detected according to the adjusted target touch resolution to achieve high touch accuracy and low touch latency. The touch operation is any touch action performed by the user on the touchscreen; in response to the touch operation, the touch detection point generates touch data.

[0056] By applying the embodiments of this application, when a touch operation on the touchscreen meets preset conditions, the application scenario identifier and the current display resolution of the touchscreen are obtained; according to the preset mapping relationship between the application scenario identifier and the touch coefficient, the touch coefficient corresponding to the current application scenario identifier is obtained; according to the display resolution and the touch coefficient, the target touch resolution is obtained; the touch resolution of the touchscreen is adjusted to the target touch resolution, so as to detect touch operations on the touchscreen according to the target touch resolution; wherein, the touch resolution is the number of touch detection points in the touchscreen used to respond to touch operations, thereby dynamically adjusting the touch resolution of the touchscreen according to the current display resolution of the touchscreen and the touch coefficient corresponding to the current application scenario, and dynamically achieving the requirements of high touch accuracy and low touch latency.

[0057] In an optional embodiment, please refer to Figure 2 The preset conditions include at least one preset application identifier. When the touch operation on the touch screen in step S10 meets the preset conditions, the current application scene identifier and the current display resolution of the touch screen are obtained, including S11~S12, as follows:

[0058] S11. When the startup trigger operation of the first application on the touch screen is detected, the application identifier of the first application and the current display resolution of the first application are obtained.

[0059] The interactive whiteboard has multiple applications installed. Application identifiers are used to identify and mark the applications installed on the whiteboard; these identifiers can include the application's name, type, installation path, etc. The first application is a third-party application installed on the whiteboard, such as WPS Spreadsheet or WPS Docs. The application identifier for the first application is used to identify and mark the first application installed on the whiteboard; it can include the application's name, type, installation path, etc. The current display resolution of the first application is the resolution used when displaying images. Specifically, WPS Spreadsheet is used for data entry, editing, presentation, and creating various complex tables, requiring dense touch detection points; therefore, a high touch resolution is needed to meet high touch accuracy requirements. WPS Docs is used for document presentations and uses a lower touch resolution to reduce touch latency.

[0060] S12. If the application identifier of the first application is a preset application identifier, obtain the application scenario identifier corresponding to the currently launched first application according to the preset mapping relationship between application scenario identifier and application identifier.

[0061] When a user taps the application icon of a first application on the touchscreen, launching the first application, the system listens for the launch of the first application and obtains its application identifier. If the application identifier of the first application is a preset application identifier, then the corresponding application scenario identifier for the first application is obtained according to the preset mapping relationship between application scenario identifiers and application identifiers. If the application identifier of the first application is not a preset application identifier, then the touch resolution of the first application is not adjusted; that is, the touch operation on the touchscreen is detected based on the original touch resolution of the first application. Since different first applications require different touch resolutions, by setting corresponding application scenario identifiers for different applications, the touch resolution of the touchscreen can be automatically and accurately adjusted dynamically.

[0062] In an optional embodiment, before step S12, steps S121-S122 are included, as follows:

[0063] S121. Obtain the application identifier corresponding to the first application on the touch screen;

[0064] S122. A preset application scenario identifier is given to the application identifier, and a mapping relationship between the application identifier and the application scenario identifier is established.

[0065] In this embodiment of the application, by establishing a mapping relationship between application identifier and application scenario identifier, after obtaining the application identifier of the first application, the application scenario identifier corresponding to the currently launched first application can be automatically and quickly obtained according to the mapping relationship.

[0066] In an optional embodiment, please refer to Figure 3 The preset conditions include at least one preset control identifier. When the touch operation on the touch screen meets the preset conditions in step S10, the current application scenario identifier and the current display resolution of the touch screen are obtained, including S13~S14, as follows:

[0067] S13. When a trigger operation of a target control within a second application on the touchscreen is detected, the control identifier of the target control and the current display resolution of the target control are obtained.

[0068] A control is an encapsulation of data and methods, and is a component with a user interface. Multiple applications are installed on the interactive flat panel, and each application contains multiple controls. Control identifiers are used to identify and mark the controls, and may include information such as the control's name, type, and installation path. The current display resolution of the control is the resolution at which the control displays an image. In this embodiment, the second application can be a self-use application installed on the touchscreen, such as the Seewo Whiteboard application. The Seewo Whiteboard application includes multiple preset controls, such as controls for Chinese character writing, musical instrument games, timing, and settings. Specifically, the use of the Chinese character writing control involves adjusting the thickness and style of Chinese characters, requiring a high touch resolution for precise writing. The use of the settings control requires a low touch resolution for low touch latency. The second application can be a third-party application whose internal controls can be monitored, such as the VLC multimedia player. Specifically, the VLC multimedia player's lyrics editing control involves adjusting the color and size of lyrics, requiring a high touch resolution for precise editing. The VLC multimedia player's settings control is used for modifying audio and video file formats, requiring a low touch resolution for low touch latency.

[0069] S14. If the control identifier of the target control is a preset control identifier, obtain the application scenario identifier corresponding to the target control according to the preset mapping relationship between application scenario identifier and control identifier.

[0070] When a user clicks on a target control within the second application, the system listens for the target control's activation, retrieves its control identifier and current display resolution, and if the target control's identifier matches a preset identifier, obtains the corresponding application scenario identifier based on a preset mapping between application scenario identifiers and control identifiers. If the target control's identifier is not a preset identifier, the touch resolution of the target control is not adjusted; that is, the touch operation on the touchscreen is detected based on the target control's original touch resolution. Since different controls within the second application require different touch resolutions, by setting corresponding application scenario identifiers for different controls, the touchscreen's touch resolution can be automatically and accurately adjusted dynamically.

[0071] In an optional embodiment, before step S14, steps S141-S142 are included, as follows:

[0072] S141. Obtain the control identifiers corresponding to each control within the second application on the touchscreen;

[0073] S142. A preset application scenario identifier is given to the control identifier, and a mapping relationship between the control identifier and the application scenario identifier is established.

[0074] In this embodiment of the application, by establishing a mapping relationship between control identifiers and application scenario identifiers, after obtaining the control identifier of the preset control in the second application, the application scenario identifier corresponding to the preset control can be automatically and quickly obtained according to the mapping relationship.

[0075] In an optional embodiment, please refer to Figure 4 Step S30, which obtains the target touch resolution based on the current display resolution and the touch coefficient, includes steps S31 to S33, as follows:

[0076] S31. Obtain the maximum touch resolution of the touchscreen;

[0077] S32. Obtain a matching first touch resolution based on the current display resolution and the touch coefficient;

[0078] S33. Compare the first touch resolution with the maximum touch resolution, and take the minimum value in the comparison result as the target touch resolution of the touch screen.

[0079] In this embodiment, after obtaining the current display resolution and the touch coefficient, the current display resolution and the touch coefficient are multiplied together, and the product is used as the first touch resolution for matching. The first touch resolution is compared with the maximum touch resolution. If the first touch resolution is less than the maximum touch resolution, the first touch resolution is used as the target touch resolution of the touchscreen; if the first touch resolution is greater than the maximum touch resolution, the maximum touch resolution is used as the target touch resolution of the touchscreen.

[0080] Based on the current display resolution and the touch coefficient, a matching first touch resolution can be obtained quickly and accurately. Since the matching first touch resolution may be greater than the maximum touch resolution during the calculation process, the first touch resolution is compared with the maximum touch resolution, and the minimum value in the comparison result is taken as the target touch resolution of the touch screen. This avoids the target touch resolution being greater than the maximum touch resolution and ensures the reliability of dynamically adjusting the touch resolution.
