[0002] During the development of touchscreen displays, it's common to test their touch response accuracy. This involves measuring the offset between the actual physical touch point and the displayed response point on the screen. The smaller the offset, the higher the touch accuracy. As a key indicator of user experience, touch accuracy is tested during product development using a set limit. The measured touch offset distance must not exceed this standard, otherwise the product will fail to meet the standard. This failure is known as touch offset.

[0003] Existing methods for measuring touch offset typically involve calibrating multiple test points on the screen. Using a stylus or other tool, the user visually targets the center of each test point. The difference between the coordinates of the touch response and the actual coordinates of the calibrated test point is calculated to determine touch accuracy. This accuracy is then compared against product design standards to determine if the standards are met. Existing touch offset detection methods are complex and can result in ambiguous results.

[0027] The present invention will be further described in detail below with reference to the accompanying drawings and examples. It will be understood that the specific embodiments described herein are intended to explain the present invention, not to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all structures.

[0028] It should be noted that this application specification does not enumerate all optional implementation methods. After reading this application specification, those skilled in the art should be able to understand that as long as the technical features do not contradict each other, any combination of technical features can constitute an optional implementation method.

[0029] In electronic devices based on touch screens, interaction can be performed directly based on the display screen, and the display and operation can be synchronized. From the perspective of user interaction experience, a device completes the detection of touch operations and the display of corresponding screens; from the perspective of subdivided functional hardware, the detection of touch operations and the display of corresponding screens are implemented through different hardware modules. Figure 2 As shown, in an electronic device 20, the touch display screen is assembled by a touch module 21 and a display screen 22 in a similar layered stacking manner, wherein the touch module 21 realizes the detection of touch operations, and the display screen 22 realizes the display of corresponding pictures. The touch detection range of the touch module 21 coincides with or nearly coincides with the display range of the display screen 22. In this setting state, the touch module 21 and the display screen 22 can establish a mapping relationship of the coordinate system based on the physical relative position relationship, so that when the touch position parameters on the touch module 21 are used on the display screen 22 through the mapping relationship, they correspond to positions that coincide or deviate within the design allowable range, so that the touch position parameters detected by the touch module 21 can accurately point to the user's touch operation target on the display screen 22.

[0030] In order to achieve the above interactive goals, when developing touch screens, it is necessary to test the accuracy of their touch responses, that is, to measure the positional offset between the actual physical touch point and the screen display response point. The smaller the offset distance, the higher the touch accuracy. The current common measurement method is: calibrate multiple test sites on the screen, aim with the human eye, use a touch pen or other tool to click on the center position of each test site, calculate the difference between the coordinates of the touch response at the time of click and the actual coordinates of the calibrated test site, thereby obtaining the touch accuracy value, and comparing it with the product standard to determine whether it meets the standard. The above operation process of multiple operations of aiming with the human eye is complicated, the judgment of the touch response coordinates and the actual coordinates is cumbersome, and the touch offset detection results are not intuitive.

[0031] In response to the above technical problems, this solution proposes a touch offset detection tool. When performing touch offset detection using the touch offset detection tool, the inspector only needs to hold the hollow tube and stick the touch head to the electronic device. The electronic device confirms the comparison point position parameters according to the first confirmation rule based on the multiple position parameters generated by the multiple touch heads, and displays the comparison points accordingly. The inspector can quickly confirm whether the offset distance is within the design requirements by observing the comparison points in the hollow tube, which simplifies the test operation process and intuitively presents the test results.

[0032] The touch offset detection tool in the embodiment of the present application can be applied to touch display screens implemented by various types of touch modules and display screen combinations, and the specific detection target is not limited by the type of touch module and / or display screen and the installation method of the two.

[0033] The following describes in detail the embodiments of the present invention.

[0034] Figure 1 A touch offset detection tool 10 provided in an embodiment of the present application includes at least two touch heads 104, a base 102, and a cylindrical hollow tube 101. The mounting ends of the at least two touch heads 104 are connected to a first side surface of the base 102. The touch ends of the at least two touch heads 104 are located in a first plane. A reference point exists on the first plane, determined according to a first confirmation rule based on the positions of the touch ends. The base 102 defines an observation hole 103 extending through the second side surface and the first side surface. The first end of the hollow tube 101 is embedded in or connected to the observation hole 103 from the second side surface. The reference point is located within a field of view when viewed through the tube of the hollow tube 101 from the second end. When using the touch offset detection tool 10 to perform touch offset detection, the at least two touch heads 104 contact a touch display screen to be tested, so that the touch display screen to be tested detects the contact positions corresponding to the at least two touch heads 104 and displays a comparison point at a comparison point position determined according to the first confirmation rule and the contact positions. The comparison point confirms the offset status to the user by determining whether the user is within the field of view when observing through the tube of the hollow tube 101.

[0035] In the embodiment of the present application, the first plane is a spatial concept used to constrain the positional relationship of the touch terminals of touch head 104. That is, the touch terminals are located in the same plane. Based on this positional relationship, all touch terminals can simultaneously contact the same plane, thereby ensuring that touch position parameters corresponding to multiple touch points can be generated when testing the touch display. Touch head 104 refers to a touch object that can be detected by the touch display to be tested. The type of touch object can be selected based on the type of touch display to be tested. For example, a touch display based on a capacitive touch module or an inductive touch module requires a capacitive touch head or an inductive touch head accordingly.

[0036] The reference point is a spatially conceptual point located on the first plane within the field of view when viewed through the second end of the hollow tube 101. This point does not physically exist. The first confirmation rule is used to characterize the relative positional relationship between the reference point and the touch terminal. That is, based on the position of the touch terminal, the first confirmation rule can unambiguously determine a unique reference point that satisfies the relative positional relationship with the touch terminal.

[0037] On the basis of confirming the position of the touch head 104 and that the touch ends are all located in the same plane, there is no strict order relationship between the reference point on the first plane, the first confirmation rule, and the field of view of the first plane in the hollow tube 101. When implementing the touch offset detection tool 10 in the embodiment of the present application, the reference point can be first confirmed according to the first confirmation rule based on the distribution of the touch ends, and then the installation position of the hollow tube 101 can be confirmed according to the reference point and the relationship between the hollow tube 101 and the reference point. Alternatively, the hollow tube 101 can be designed first based on the convenience of use, and then the field of view of the pipe in the first plane can be confirmed. Finally, a point can be taken from the field of view as a reference point, and then the relative position relationship between the reference point and the touch end can be confirmed, that is, the first confirmation rule can be confirmed. In the overall implementation process, the reference point can be controlled to be located at the center of the field of view of the pipe in the first plane.

[0038] The cylindrical hollow tube 101 is used to view information within the field of view. If a marker is set at the reference point, the marker can be seen through the pipe of the hollow tube 101; if the reference point is located at the center of the field of view of the first plane, the marker can be seen at the center of the field of view through the pipe of the hollow tube 101. The size of the specific pipe is set according to the touch accuracy requirement. The higher the touch accuracy requirement, the smaller the pipe. The shape of the observation hole 103 is adapted to the hollow tube 101. Part of the hollow tube 101 is embedded in the observation hole, or the hollow tube 101 is connected to the observation hole 103 so that the observation hole 103 serves as an extension of the pipe. Overall, the opening of the observation hole 103 and the matching relationship between the hollow tube 101 and the observation hole 103 do not affect the observation of the reference point through the pipe.

[0039] Based on the clear relative position relationship of each component on the touch offset detection tool, the touch offset detection tool can be used to detect the touch position parameters corresponding to the touch terminal on the touch module. When the display screen responds based on the touch position parameters, a comparison point is generated on the display screen according to the first confirmation rule. If the coordinate system of the touch module and the coordinate system of the display screen are adapted to overlap, and because the contact between the touch terminal and the touch display screen can be regarded as the overlap of the first plane and the touch display screen, then the comparison point should appear exactly at the position of the reference point, which is equivalent to a marker appearing at the position of the reference point. The worse the degree of adaptation between the coordinate system of the touch module and the coordinate system of the display screen, the greater the deviation of the display position of the comparison point from the reference point, that is, the greater the touch offset, so that the touch offset detection result can be directly observed through a single detection operation. When performing touch offset detection using this touch offset detection tool, the inspector only needs to hold the hollow tube and stick the touch head to the electronic device. The electronic device confirms the comparison point position parameters according to the first confirmation rule based on the multiple position parameters generated by the multiple touch heads, and displays the comparison points accordingly. The inspector can quickly confirm whether the offset distance is within the design requirements by observing the comparison points in the pipe, which simplifies the test operation process and intuitively presents the test results.

[0040] Based on the above overall design concept, the touch head 104, base 102 and cylindrical hollow tube 101 can have various specific installation details. For example, the extension line of the hollow tube 101 can intersect the first plane at an angle, that is, the hollow tube 101 does not need to be perpendicular to the touch screen during detection, as long as the first confirmation rule is accurately set and the reference point is within the field of view of the tube.

[0041] In order to simplify production and manufacturing, be convenient and comfortable to use, or be easy to store, the implementation details of the touch offset detection tool can be further designed.

[0042] In a specific design approach, such as Figure 3 As shown, the base 102 of the touch offset detection tool 10 is a cylindrical base; at least two touch heads 104 are perpendicular to the first side; and the hollow tube 101 is perpendicular to the second side. Using a cylindrical base, such as a cylindrical base, a rectangular base, or a cube base, the hollow tube 101 and the touch heads 104 can be perpendicularly arranged on two parallel, opposite sides (which may be the bottom surface according to geometric naming conventions). During specific testing, the hollow tube 101 is perpendicular to the touch display screen of the electronic device 20, providing a more comfortable viewing angle for the tester. The cylindrical hollow tube 101 can be a round tube or a square tube, and the opening of the observation hole 103 can be adapted to the shape of the hollow tube 101.

[0043] To ensure that the relative positional relationship between the hollow tube 101 and the touch screen in the vertical direction is unique during detection, the number of touch heads 104 is at least three, and the three touch heads 104 are not on the same straight line. When the unique first plane determined by the three touch heads contacts the touch screen, the hollow tube 101 and the touch screen have only a unique angle, such as a right angle, thereby avoiding detection deviation due to operational deviation during detection.

[0044] To facilitate the first confirmation rule during production, the touch tip of each touch head is located at a different vertex of a regular polygon. Accordingly, the reference point can be set to the center of the regular polygon. In terms of overall structural consistency, the shape of the first side surface is identical or similar to that of the regular polygon. Calculating the reference point based on the regular polygon is relatively simple, making it faster and more accurate to confirm the location of the viewing hole.

[0045] Please refer to Figure 5 , which is a flow chart of a touch offset detection method provided by an embodiment of the present application, the touch offset detection method is implemented by an electronic device. Please refer to Figure 5 The touch offset detection method includes steps S110 to S140:

[0046] Step S110: Entering a touch offset detection mode, and displaying a writing detection interface in the touch offset detection mode.

[0047] Testing of touch screen displays is typically performed during the R&D phase. During this phase, hardware assembly adjustments and data parameter settings can be performed on the touch screen, which is already in its component state. Once the coordinate system of the touch module and display is aligned, the system can be delivered for production according to the finalized assembly plan and parameters. The touch offset detection method in the embodiments of this application is used to test the adaptation effect during the intermediate stages of assembly adjustment and parameter setting. During the R&D phase, the touch screen, while still in its component state, can be connected to an electronic device via an interface, which then executes a corresponding program to complete the touch offset detection method based on the touch offset detection tool in the previous embodiment.

[0048] The electronic device has been previously connected to the touch display screen to be tested, and has completed the settings related to the pre-adaptation of the coordinate system of the touch module and the display screen. On this basis, it can receive the touch position parameters detected by the touch module, and confirm a position on the display screen to respond according to the adaptation relationship between the touch position parameters and the settings. If the adaptation effect is not finally confirmed, the touch offset detection mode can be entered, and the writing detection interface is displayed in the touch offset detection mode. The writing detection interface is a detection interaction interface developed corresponding to the aforementioned touch offset detection tool. The writing detection interface can receive touch operations and display written content. Different from the writing-is-what-you-get method on application software such as whiteboard applications, multi-point writing generates multiple handwritings. The writing detection interface in the embodiment of the present application implements a writing method in which multi-point writing operations generate one handwriting.

[0049] The writing detection interface can be an application interface of a test application developed separately, or it can be a sub-interface corresponding to a sub-function integrated in a writing application (such as a whiteboard application). Accordingly, entering the touch offset detection mode can be achieved by opening the test application, or by opening a sub-function of the writing application. In the touch offset detection mode, the data processing process of the system layer remains unchanged, that is, the system layer keeps processing the touch position parameters according to the adaptation scheme, and distributes them to the application corresponding to the currently displayed writing detection interface for processing. For example, the original position (a, b) detected by the touch module is processed according to the adaptation scheme to correspond to the response position (a`, b`) of the display screen. The goal of the adaptation is to make (a, b) and (a`, b`) the same position (or a highly close position) in terms of interaction effect. The goal of the touch offset detection is to confirm how large the deviation between (a, b) and (a`, b`) is.

[0050] Step S120: Acquire a plurality of touch position parameters detected by the touch module when a multi-touch operation is performed on the writing detection interface using a touch offset detection tool.

[0051] The touch offset detection tool in the embodiment of the present application includes at least two touch heads, a base, and a cylindrical hollow tube; the mounting ends of the at least two touch heads are connected to a first side surface of the base, the touch ends of the at least two touch heads are located in a first plane, and a reference point exists on the first plane that is determined according to a first confirmation rule based on the position of the touch ends; the base has an observation hole extending through the second side surface and the first side surface, the first end of the hollow tube is embedded in or connected to the observation hole from the second side surface, and the reference point is located within the field of view when viewed through the hollow tube from the second end of the hollow tube. After the writing detection interface is displayed, the inspector holds the touch offset detection tool so that the multiple touch ends of the touch heads contact the touch display screen. For the electronic device, the touch module detects a multi-touch operation. Even if there is an initial adaptation deviation, the multi-touch operation is basically guaranteed to occur within the writing detection interface for the display screen. Therefore, it can be directly defined here as obtaining a multi-touch operation on the writing detection interface and correspondingly obtaining multiple touch position parameters detected by the touch module. The specific detection of touch position parameters is widely implemented in the touch control field and will not be described in detail here.

[0052] Step S130 : confirming comparison point position parameters according to a first confirmation rule based on the plurality of touch position parameters.

[0053] The touch position parameters are position parameters detected by the touch module, and the relative position relationship between each touch position parameter corresponds to the relative position relationship of the touch end on the touch offset detection tool. The comparison point position parameters are confirmed according to the first confirmation rule based on multiple touch position parameters. First, the touch position parameters are converted into display position parameters in the coordinate system of the display screen based on the adaptation relationship between the coordinate system of the touch module and the display screen. This process is a proportional conversion. After the conversion, the display position parameters still have the same relative position relationship as the touch end and the touch position parameters. The touch end is confirmed to have a unique reference point according to the first confirmation rule, and the display position parameters can also confirm a unique position parameter according to the first confirmation rule, that is, the comparison point position parameter.

[0054] According to the first confirmation rule, the mathematical relationship between the display position parameters and the comparison point position parameters can be confirmed, and then the comparison point position parameters can be obtained based on the display position parameters according to the mathematical relationship. For example, the four display position parameters correspond to the four vertices of a quadrilateral, and the first confirmation rule is the intersection of the diagonals of the quadrilateral. If the four display position parameters are (x1, y1), (x2, y2), (x3, y3) and (x4, y4), the coordinates of the diagonal intersection point (x c ,y c ), that is, the center point coordinates, can be calculated as follows:

[0055]

[0056]

[0057] The above calculation method can be applied to any quadrilateral, including rectangles, parallelograms, rhombuses, etc.

[0058] Step S140: displaying the comparison points on the writing detection interface according to the comparison point position parameters.

[0059] The comparison point can be any iconic pattern display, such as a dot, a cross pattern, etc., which can be displayed at the comparison point position parameter.

[0060] In the embodiments of the present application, the electronic device provides the contrast display required for the tester to perform touch offset detection and judgment. The electronic device itself may not be able to complete the judgment of the offset result. For the tester, if the presence of a landmark pattern within the field of view can be observed through the hollow tube, it can be confirmed that the touch offset is relatively small or acceptable; if the landmark pattern is located in the center of the field of view through the hollow tube, it can be confirmed that the touch offset is basically negligible; if the landmark pattern cannot be observed within the field of view through the hollow tube, it indicates that the touch offset does not meet the design requirements.

[0061] The specific detection principle can be Figure 4 Do intuitive comparative analysis. Figure 4 In the figure, it is assumed that the four black dots 23 represent the four position points corresponding to the touch position parameters. According to the four touch position parameters, the position parameters of the reference point 231 can be uniquely confirmed, but the position is not actually displayed according to the position parameters of the reference point 231. According to the four touch position parameters, the four display position parameters in the display screen can also be obtained, that is, the position parameters of the positions of the four slash crosses 24, that is, the display position parameters, but these four positions are not actually displayed. According to the four display position parameters, the comparison point position parameters can be obtained, and the black cross 241 will be displayed as an indicative pattern at the comparison point position parameters. In the above position parameter change process, the relative position relationship between the reference point 231 and the four black dots 23 is the same as the relative relationship between the black cross 241 and the four slash crosses 24. If the touch module is properly adapted to the display screen, the display positions of the four black dots 23 and the four slash crosses 24 should overlap, and the black cross 241 should be seen at the reference point. If the touch module is not properly adapted to the display screen, it will appear Figure 4The effect is that the black cross 241 as the iconic pattern appears at the position of the offset reference point 231, the offset is large, and the adaptation of the coordinate system of the touch module and the display screen has not yet met the design requirements. If the black cross 241 appears exactly at the position of the reference point 231, that is, at the center of the field of view when observing through the hollow tube, it can be confirmed that the four oblique crosses 24 appear exactly at the positions of the four black origins 23, that is, the display position parameters obtained according to the touch position parameters coincide. Through the above design principles, the touch offset detection tool and touch offset detection method provided in this solution can intuitively see the touch offset detection results with only one operation.

[0062] In another optional implementation, the writing detection interface also displays a result confirmation control; accordingly, the touch offset detection method also includes: confirming and recording the detection result according to a single-point click operation acting on the result confirmation control. In an embodiment of the present application, the detection personnel can only judge whether the comparison point is within the field of view or in the general position of the field of view by the naked eye, that is, the detection personnel can basically only make qualitative judgments, not quantitative judgments. Therefore, the result confirmation control can be set according to the judgment ability of the detection personnel, such as whether it is within the field of view, or roughly judge the position in a certain direction of the field of view, or whether it is in the center. By recording the test results, the assembly method and / or parameter configuration of the touch module and the display can be further adjusted with reference to the test results in the subsequent research and development process, or it can be confirmed that the current adaptation method has met the design requirements, and the touch position parameters can obtain highly corresponding display position parameters based on the adaptation relationship.
