[0035] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only the parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0036] It should be noted that the present application specification does not enumerate all optional implementation modes. After reading the present 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 the technical features can constitute an optional implementation mode.

[0037] In an interactive device based on a touch screen, interaction can be performed directly based on the display screen, and an interactive effect of synchronized display and operation can be presented. 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. In an interactive device, a touch screen is assembled by a touch module and a display screen in a similar layered overlapping manner, wherein the touch module detects touch operations and the display screen displays corresponding screens. The touch detection range of the touch module overlaps or nearly overlaps with the display range of the display screen. In this setting state, the touch operation of the touch module will generally have a corresponding screen presentation on the display screen, such as the presentation of the writing handwriting corresponding to each touch point in the writing operation.

[0038] In order to avoid the defect that the defined touch operation cannot be displayed accordingly when developing software for interactive devices, multi-point testing is usually performed on the interactive device to confirm the limit of the number of simultaneous multi-point touch points that the interactive device can support. The existing testing method is to set a multi-point row pen for each point, and use a different multi-point row pen each time, which is equivalent to constantly changing the number of pen tips used for writing with the multi-point row pen, and finally confirming the limit of touch points. This testing method requires the preparation of multiple multi-point row pens. When there are new testing requirements, such as interactive devices of new size or response accuracy, and new multi-point touch function designs, the multi-point row pen needs to be remade. The production cost and management cost of the test equipment for multi-point testing are high, and the test operation is complicated.

[0039] In response to the above technical problems, an embodiment of the present application proposes a multi-point testing tool. When the multi-point testing tool is used to perform multi-point testing on an interactive device to be tested, the retractable state of the pen tip is adjusted sequentially on a multi-point testing tool according to the testing process. Each time the adjustment is made, a writing operation is performed on the interactive device to be tested. To implement multi-point testing, only one multi-point testing tool needs to be prepared and used, which reduces the production and management costs of the test equipment for implementing multi-point testing, and also reduces the complexity of the test operation.

[0040] The multi-point test tool in the embodiment of the present application can be applied to interactive devices generated by touch screens based on various types of touch modules and display screens, 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. For example, a conference tablet with a large touch screen that can be used by multiple people at the same time.

[0041] The following is a detailed description of the various embodiments of the present invention.

[0042] Figure 1A multi-point testing tool 10 is provided in an embodiment of the present application. The multi-point testing tool 10 includes a mounting rod 101 and a plurality of pen tips 102. Each pen tip 102 is mounted on the mounting rod 101 through a telescopic device. The touch ends of the pen tips 102 can be located in the same plane or in different planes under the telescopic adjustment of the telescopic device. When the multi-point testing tool 10 is used to perform a multi-point test, the telescopic device is controlled to perform telescopic changes and enter a plurality of telescopic states in sequence. In each telescopic state, the multi-point testing tool 10 is used to complete the same writing operation on the interactive device to be tested along the same moving path and take a screenshot, so as to confirm the upper limit of the number of writing points of the interactive device to be tested according to the similarity of two adjacent screenshots. Each subsequent telescopic state adds a pen tip 102 at the writing length compared to the adjacent previous telescopic state. The mounting rod 101 may be a structure that is the same as a column in the geometric sense (e.g., a cylinder or a prism), or may be a column-like body with some deviations in details (e.g., chamfers). The pen tip 102 may be regarded as having a connection end and a touch end, wherein the connection end is used to be mounted to the mounting rod 101 through a telescopic device, and the touch end is used to generate a touch point when performing a multi-point test. The telescopic device may be an elastic telescopic device with multiple levels of positioning, and each level of positioning makes the touch end at a different extension length; or it may be a sliding telescopic device based on a slide rail, and the touch end is temporarily fixed by a positioning bolt or the like after sliding to a predetermined position. It should be understood that each telescopic device is connected to only one pen tip 102. Because the telescopic device is extended and retracted in conjunction with the corresponding pen tip 102 to move, the distance between the touch end and the mounting rod 101 can be adjusted. When the multi-point test tool 10 in the embodiment of the present application is used for writing, the touch end farthest from the mounting rod 101 generates a touch point on the interactive device. There may be multiple such touch ends, and these touch ends are in the same plane, and the other touch ends are in other planes. In the embodiment of the present application, the same plane is a spatial concept used to constrain the positional relationship of the touch end of the pen tip 101, that is, when the touch end is located in the same plane farthest from the mounting rod 101, the touch end of the plane can contact with a plane at the same time, thereby ensuring that touch position parameters corresponding to multiple touch points can be generated when performing a multi-point test on the interactive device. By adjusting the number of touch ends of the plane, the number of touch points during the multi-point test can be adjusted. Figure 2 As shown, the touch ends of all the pen tips 102 of the multi-point test tool 10 are in contact with the surface of the touch display screen of the interactive device 30 to be tested. The pen tip 102 refers to a touch object that can be detected by the interactive device 30 to be tested. Specifically, the type of touch object can be selected according to the type of the touch display screen of the interactive device 30 to be tested. For example, a touch display screen based on a capacitive touch module or an inductive touch module requires a capacitive pen tip or an inductive pen tip accordingly.

[0043] A gripping hole may be provided on the mounting rod 101, or Figure 1The grip 103 is mounted on the mounting rod 101. When the test is performed manually, the mounting rod 101 or the grip 103 can be gripped through the grip hole to complete the writing operation during the test.

[0044] In order to improve the test effect, the parts of the multi-point test tool 10 that need to move can be designed as electronic control parts, for example, the telescopic device is set as a motor, specifically a motor-driven translation device; the multi-point test tool 10 also includes a fixed bracket and a moving device; the mounting rod 101 is fixedly mounted on the moving device, and the moving device is used to move in the moving plane confirmed by the fixed bracket, and the moving plane is parallel to the plane where the touch terminal is located. When performing a multi-point test, the fixed bracket and the interactive device to be tested remain relatively still, and the moving plane confirmed by the fixed device is parallel to the surface of the touch display screen of the interactive device to be tested. The distance between the moving plane and the surface of the touch display screen is adjusted to enable the touch terminal at the front end (compared to the mounting rod 101 located at the rear end) to contact the surface of the touch display screen to complete the writing operation, and then control the movement of the moving device to drive the pen head 102 to complete the writing operation required for the multi-point test. Generally speaking, multiple pen heads 102 are installed in a row on the mounting rod 101, and the moving direction during the writing operation is perpendicular to the arrangement direction, and is at an angle close to 90° or not 0°, to ensure that the moving trajectories corresponding to different pen heads 102 do not overlap during the multi-point test.

[0045] In an optional implementation, the mounting rod 101 or the mobile device is provided with a distance sensor, the detection direction of the distance sensor points to the plane where the touch end is located, and the distance sensor is used to detect the distance to the nearest signal reflection surface in front of the touch end. When the distance matches the preset touch distance, it can be confirmed that the touch end has contacted the interactive device to be tested, and the mobile device can be controlled to move and start the writing operation, thereby avoiding invalid movement or excessive contact pressure that may cause damage to the multi-point test tool or the interactive device to be tested.

[0046] Based on the above multi-point testing tool implemented based on electronic control components, the embodiment of the present application further provides a multi-point testing method to achieve automatic control of the multi-point testing tool and automatic judgment of the test results during the multi-point testing process.

[0047] Please take the exam Figure 7 , which is a method flow chart of a multi-point testing method provided in an embodiment of the present application, and the multi-point testing method is implemented by an electronic device. Please refer to Figure 7 The multi-point testing method includes steps S110 to S150:

[0048] Step S110: when a multi-point test instruction is received while a data connection is established with the interactive device to be tested, a writing software wake-up instruction is sent to the interactive device to be tested, so that the interactive device to be tested starts the writing software to display the writing handwriting according to the writing operation.

[0049] The electronic device for implementing the multi-point testing method in the embodiment of the present application may be as follows: Figure 3 and Figure 4 The multi-point test tool 10 and the test computer 20 shown in the figure can be implemented by combining Figure 5 The multi-point test tool 10 shown is implemented independently, or as Figure 6 The test computer 20 shown is implemented separately, wherein the interactive device 30 to be tested is configured with a touch screen 31, which is also a direct test object in the embodiment of the present application. Regardless of the electronic device implemented in which way, it is necessary to establish a data connection with the interactive device 30 to be tested, and the data connection is a wireless data connection or a USB data connection.

[0050] exist Figure 3 The multi-point test tool 10 shown includes the various components for realizing electric control as described above, and also includes a built-in control chip. The control chip serves as the control core of the multi-point test tool 10. When the multi-point test tool 10 establishes a data connection with the test computer 20, the control chip can perform data transmission and reception processing with the test computer 20. The objects of the data transmission and reception processing specifically include the indication of the telescopic state, the result of the distance detection, etc. The test computer 20 also establishes a data connection with the interactive device 30 to be tested for sending instructions and receiving data. Figure 3 Any data connection in can be a wireless data connection or a USB data connection. Figure 3 Each hardware body in the system is powered independently.

[0051] Figure 4 The multi-point test tool 10 shown can be regarded as the core of the multi-point test, that is, the test computer 20 and the interactive device 30 to be tested need to establish a data connection with the multi-point test tool 10 in advance, and it is a wired USB data connection. The data connection between the test computer 20 and the interactive device 30 to be tested is realized through the USB HUB 105 inside the multi-point test tool 10. In this state, the power cord 106 of the multi-point test tool 10 can be set as a plug connected to the mains for power supply, or it can be set as a USB connector connected to the test computer 20 or the interactive device 30 to be tested for power supply.

[0052] Figure 6 The multi-point test tool 10 shown can be regarded as Figure 1On the basis of the multi-point test tool 10 shown, a control chip 104 with data processing capability and a display module (not shown in the figure) for realizing the display of test results are further provided, which is equivalent to that the control of the electric control components and the control of the multi-point test process can be completed in a centralized manner in the multi-point test tool 10. The power cord 106 of the multi-point test tool 10 can be set to be connected to the mains power supply by a plug, or it can be set to be connected to the interactive device 30 to be tested by a USB connector for power supply. If a USB connector is used, data connection can be completed synchronously through the USB connector, and data transmission and power supply can be completed through one connection.

[0053] Figure 7 The electronic device shown can be considered as Figure 1 The multi-point test tool 10 shown is completely controlled by the test computer 20, which of course also establishes a data connection with the interactive device to be tested 30. The specific data connection method is generally the same as described above and will not be described separately here.

[0054] It should be noted that the test computer 20 mentioned above is not a completely redesigned computer, but a computer that is designed based on the existing technology and the test scheme in the embodiment of the present application. During the test, it has the ability to control the multi-point test tool 10 and to provide corresponding operation instructions and data acquisition for the interactive device 30 to be tested.

[0055] Based on the established data connection, the electronic device (such as the multi-point test tool 10 and the test computer 20 mentioned above) can send a writing software wake-up instruction to the interactive device to be tested, so that the interactive device to be tested starts the writing software to display the writing handwriting according to the subsequent writing operation. The writing software can be a specially developed software or an existing software that can realize handwriting handwriting input. When the writing software is just started, only the default interface content of the writing software is displayed in the corresponding window, and other writing handwriting is not displayed.

[0056] Step S120: sending a first screen capture instruction to the interactive device to be tested, so as to capture a screen image of the interactive device to be tested.

[0057] After starting the writing software, the electronic device sends a first screen capture instruction to the interactive device to be tested, so that the interactive device to be tested captures a screen image containing a blank window of the writing software as a reference for subsequent judgment.

[0058] Step S130: Control the telescopic device to perform telescopic changes and enter multiple telescopic states in sequence. In each telescopic state, control the mobile device to follow the same preset moving path to complete a writing operation on the interactive device to be tested. After each writing operation is completed, send a second screenshot instruction to the interactive device to be tested to capture the screen image of the interactive device to be tested. In the first telescopic state, the touch end of a pen tip extends to the writing length, and each subsequent telescopic state adds a pen tip at the writing length compared to the adjacent previous telescopic state.

[0059] In the specific test process, the same as the manual test process, the embodiment of the present application starts with a pen tip, and the pen tips that can be used for writing operations are added one by one to obtain a retracted state. The specific newly added pen tips that may be used for writing operations are quickly and accurately realized by sending an extension command to the motor. Each newly added pen tip completes a writing operation according to the same preset moving path. If the writing operation is completed smoothly, the latter writing operation will add a new writing handwriting compared to the adjacent previous writing operation, while other writing notes will completely overlap or highly overlap (because of slight deviations caused by errors in mechanical movement). The writing handwriting corresponding to each writing operation is correspondingly captured by the second screenshot command and exists in the screen image.

[0060] In order to avoid interference between the front and back contents in the screen image, each time a writing operation is completed, a handwriting clearing instruction is sent to the interactive device under test to clear the handwriting displayed in the window of the writing software, ensuring that the handwriting captured each time is the handwriting generated by the current writing operation, thereby ensuring the accuracy of the test results by ensuring the accuracy of the benchmark test data.

[0061] The various instruction methods in the embodiments of the present application are determined according to the data connection method. For example, based on USB, the adb start command can be used to call up the writing software, and the specific sending of instructions and data can also use other existing sending and receiving methods. The specific captured screen images can be sent by the interactive device to be tested as soon as they are captured, or the screen images captured by the two most recent times can be sent each time.

[0062] Step S140: confirming the similarity between two adjacent captured screen images.

[0063] In terms of the response to each writing operation, if the response is normal, the handwriting will be different from the previous one, that is, the writing operation that can respond normally will be displayed differently because the number of pen tips involved in each writing operation is different. The similarity can be used to determine whether the current writing operation can respond normally. The specific similarity can be determined by first extracting the feature points of the two screen images through a SIFT (Scale-invariant feature transform) feature detector, and then establishing a FLANN (Fast Library for Approximate Nearest Neighbors) matcher to align the extracted feature points, and confirm the similarity based on the aligned feature distance.

[0064] Step S150: confirming the upper limit of the writing points of the interactive device to be tested according to the similarity, and ending the multi-point test.

[0065] When the similarity reaches the preset upper limit of similarity, it is confirmed that the number of pen tips in the previous retractable state of the corresponding two retractable states is the upper limit of the number of writing points of the interactive device to be tested, and the multi-point test is ended. For example, when the number of pen tips of the writing length is 19 and 20, the preset upper limit of similarity is reached 99%, and it can be confirmed that the interactive device to be tested cannot process more touch points, and the upper limit of the number of writing points is 19. At this time, the multi-point test can be ended. The specific test process can be to perform a similarity judgment once each writing operation is completed, including a judgment with the upper limit of the number of writing points. This method can complete the detection with the minimum number of writing operations; it can also be that after performing a preset number of multiple writing operations, multiple similarity judgments are concentrated. This method can balance the comparison speed and the number of writing operations; it can also be that after performing the number of writing operations corresponding to the number of pen tips of the multi-point test tool, multiple similarity judgments are finally performed. This method can basically confirm that the final test result is directly obtained.
