The character " / " generally represents that the front and rear associated objects are in an "or" relationship.

[0035] The present application provides a virtual teaching aid display method, which is applied to a touch device, which can be a capacitive touch screen, an infrared touch screen, etc. In the present application, the touch device is an infrared touch device.

[0036] Please refer to Figure 1 , the infrared touch device 100 includes an infrared emitter 101, an infrared receiver 102 and a pressure sensing device, the infrared emitter 101 and the infrared receiver 102 are oppositely arranged, the infrared emitter 101 is sequentially turned on and emits infrared signals under the control of the controller, the infrared signals propagate on the surface of the infrared touch device 100, and the corresponding infrared receiver 102 receives the infrared signals.

[0037] When the touch object 200 contacts the surface of the infrared touch device 100, the infrared signal is blocked, and the infrared touch device determines the position where the touch object 200 contacts the infrared touch device 100 and the shape of the touch object according to the change of the infrared signal received by the infrared receiver 102, and the pressure sensing device is used to detect the pressure of the touch object 200.

[0038] Please refer to Figure 2 , the virtual teaching aid display method of the present application comprises the following steps:

[0039] S110: obtaining touch data generated by the teaching aid contacting the touch device; wherein the touch data comprises a first touch feature parameter and a first pressure parameter;

[0040] The first touch feature parameter is used to determine the size, shape, area and other information of the touch object. Specifically, the first touch feature parameter can include the minimum width, the maximum width, the contact area, the parallel projection width under different angles and other feature parameters.

[0041] In the present application, the touch object can be a teaching aid, and the teaching aid can be an object with a predetermined size and a predetermined shape, such as a triangular plate, a rectangular plate, etc. Preferably, the height of the teaching aid is greater than the height of the infrared light emitted by the infrared emitter 101, so as to ensure that the touch device can recognize the teaching aid and avoid missing recognition of the teaching aid.

[0042] The first pressure parameter is used to determine the pressure value generated by the touch object to the touch device. The first pressure parameter is used to determine the size of the force applied by the user to the teaching aid.

[0043] S120: determining shape information of a virtual teaching aid to be generated according to the first touch feature parameter;

[0044] The shape information is used to determine the shape of the virtual teaching aid to be generated. The virtual teaching aid is a virtual object corresponding to a teaching aid used on a computer or a mobile device. The virtual teaching aid can be used on the computer or the mobile device to realize the use of the virtual teaching aid.

[0045] S130: generating a virtual teaching aid according to the shape information;

[0046] Specifically, a plurality of virtual teaching aids can be pre-stored in the database. The shape information is used to determine the corresponding virtual teaching aid. When the virtual teaching aid is generated, the corresponding virtual teaching aid is obtained from the database according to the shape information. After the virtual teaching aid is generated, the generated virtual teaching aid can be displayed on the display interface, or the virtual teaching aid can not be displayed.

[0047] S140: determining size information of the virtual teaching aid according to the first pressure parameter, and adjusting the size of the virtual teaching aid according to the size information;

[0048] The size information is used to determine the size of the virtual teaching aid to be generated. Specifically, the size of the virtual teaching aid can increase with the increase of the first pressure parameter, and decrease with the decrease of the first pressure parameter.

[0049] S150: displaying the virtual teaching aid on the display interface.

[0050] The display interface can be the display interface of the device executing the virtual teaching aid display method of the present application, or the display interface of the display device connected to the device executing the virtual teaching aid display method of the present application. The display device can be a display screen, a whiteboard or the like used in classroom teaching.

[0051] In the embodiments of the present application, by obtaining touch data generated when a teaching aid contacts a touch device, determining shape information of a virtual teaching aid to be generated according to a first touch feature parameter, and determining size information of the virtual teaching aid to be generated according to a first pressure parameter, the virtual teaching aid can be generated according to the actual teaching aid, and the types of virtual teaching aids are enriched. When a user needs to add a virtual teaching aid during a class, the user only needs to contact the actual teaching aid with the touch device, and the corresponding virtual teaching aid can be automatically generated and displayed according to the actual teaching aid. The user does not need to perform complex operations, the virtual teaching aid generation efficiency is improved, and the teacher can more conveniently perform classroom teaching.

[0052] In step S110, the touch data is data generated when the touch device detects that a touch object contacts. However, when the touch object contacts the touch device, the touch object is not necessarily a teaching aid, but can also be a human hand, a writing pen or other touch objects. Therefore, as shown in FIG. 2, the touch data can be obtained by the touch device, and the touch data is sent to the server. Figure 3In a preferred embodiment, the step of acquiring the touch data generated by the teaching aid contacting the touch device specifically comprises:

[0053] S111: If the first touch feature parameter satisfies the teaching aid recognition condition, it is determined that the touch data is data generated by the teaching aid contacting the touch device.

[0054] The teaching aid recognition condition is used to determine whether the touch object is a teaching aid. The teaching aid recognition condition can be set according to the shape of the teaching aid. For example, when the teaching aid is a triangular board, the teaching aid recognition condition can be set as that the shape of the touch object is a triangle.

[0055] S112: If the first touch feature parameter does not satisfy the teaching aid recognition condition, it is determined that the touch data is not data generated by the teaching aid contacting the touch device.

[0056] After it is determined that the touch data is not data generated by the teaching aid contacting the touch device, the touch data can be discarded, or in another embodiment, a corresponding touch track can also be generated according to the touch feature parameter of the touch data and displayed on the display interface.

[0057] In the embodiments of the present application, the first touch feature parameter includes a contact area, and the teaching aid recognition condition is that the contact area is greater than a contact area threshold. When the contact area of the touch object is greater than the contact area threshold, it is considered that the touch object is likely to be a teaching aid. At this time, the shape information of the virtual teaching aid to be generated is determined according to the first touch feature parameter.

[0058] In step S120, when the shape information of the virtual teaching aid to be generated is determined, the first touch feature parameter can be compared with the touch feature parameters of the preset shapes. When the first touch feature parameter is consistent with the touch feature parameter of a certain preset shape, it is determined that the shape of the virtual teaching aid is the preset shape.

[0059] Specifically, the step of determining the shape information of the virtual teaching aid to be generated according to the first touch feature parameter specifically comprises:

[0060] The first touch feature parameter is compared with the touch feature parameters of different virtual teaching aids to acquire the shape information of the virtual teaching aid corresponding to the first touch feature parameter.

[0061] In the present application, the touch feature parameters of different virtual teaching aids can be the touch feature parameters of at least one virtual teaching aid input in advance, wherein the shape of each virtual prop is different.

[0062] The touch feature parameters can include length, width, contact area, length of infrared light parallel projection at different angles, and the like.

[0063] The application compares the first touch feature parameter with the touch feature parameter of the pre-input virtual teaching aid one by one, determines that the first touch feature parameter is consistent with the touch feature parameter of the pre-input virtual teaching aid when the error between the first touch feature parameter and the touch feature parameter of the pre-input virtual teaching aid is less than the error threshold, and acquires the shape information of the virtual teaching aid to be generated according to the shape of the virtual teaching aid.

[0064] When placing the teaching aid, the user usually has difficulty in placing the teaching aid at the same angle every time. When the teaching aid is placed at an angle, the shape of the virtual teaching aid cannot be matched according to the first touch feature parameter. Therefore, in order to improve the accuracy of the virtual teaching aid generation, the first touch feature parameter includes a first parallel projection width, the touch feature parameter includes a parallel projection width of at least one angle, the shape information includes a rotation angle, and the step of acquiring the shape information of the virtual teaching aid corresponding to the first touch feature parameter includes:

[0065] The first parallel projection width is matched with the parallel projection width of at least one angle one by one. If the matching is successful, the rotation angle of the virtual teaching aid to be generated is determined according to the angle of the matched parallel projection width.

[0066] The first parallel projection width refers to the parallel projection width of the current teaching aid, and the parallel projection width of at least one angle can be the parallel projection width of the preset teaching aid matched with the shape of the current teaching aid.

[0067] As shown in Figure 4 The parallel projection width refers to the width value of the left and right boundaries (such as the identification line shown in Figure 4 The left and right boundaries are the boundaries of the two end points (the leftmost / rightmost, or the lowermost / uppermost) of the intersection region of the object and the parallel straight line under the parallel straight projection of the specified angle. In the application, the distance between the left and right boundaries of all the occluded light rays at the same angle can be counted as the projection width at the current angle.

[0068] Specifically, the first parallel projection width can be matched with the parallel projection width at 0°. If the matching is successful, 0° is taken as the rotation angle of the virtual teaching aid to be generated. If the matching is unsuccessful, the next parallel projection width at an angle is matched in turn according to a preset adjustment value. For example, when the adjustment value is 1, the first parallel projection width can be matched with the parallel projection width at 1°. If the matching is successful, 1° is taken as the rotation angle of the virtual teaching aid to be generated. If the matching is unsuccessful, the above steps are repeated until the parallel projection width at the corresponding angle is matched. At this time, the rotation angle of the virtual teaching aid to be generated is determined according to the matched angle.

[0069] It should be noted that, if the first parallel projection width does not match the parallel projection width of all angles of the preset teaching aid, it can be considered that the currently detected teaching aid is not the preset teaching aid, or in another embodiment, an abnormal prompt information can also be sent to prompt the user to view and adjust the current abnormal situation. The abnormal prompt information is used to prompt the user that the current teaching aid matching exists an abnormality.

[0070] In step S140, after the first touch feature parameter matches the corresponding shape and rotation angle, the size information of the virtual teaching aid can be determined by reading the first pressure parameter of the pressure sensing device, so as to determine the size of the generated virtual teaching aid according to the size information.

[0071] As shown in FIG. 1, in one embodiment, the virtual teaching aid display method further includes the following steps: Figure 5

[0072] S210: acquiring a second pressure parameter in response to a pressing operation of the teaching aid contacting the touch device;

[0073] S220: adjusting the size of the virtual teaching aid according to the second pressure parameter, and displaying the adjusted virtual teaching aid on the display interface.

[0074] The second pressure parameter can be a pressure value generated by the user pressing the teaching aid.

[0075] In this application, the initial size of the virtual teaching aid is determined according to the first pressure parameter, and after receiving the pressing operation of the teaching aid, the size of the virtual teaching aid is adjusted according to the second pressure parameter.

[0076] Specifically, the size of the virtual teaching aid can be increased with the increase of the second pressure parameter of the user pressing the teaching aid, and the increased size value can be set according to the actual needs of the user.

[0077] In the embodiment of the present application, after generating and displaying the virtual teaching aid, the user can quickly adjust the size of the generated virtual teaching aid by pressing the teaching aid, without complicated operation, thereby improving the user experience.

[0078] As shown in FIG. 1, in one embodiment, the virtual teaching aid display method further includes the following steps: Figure 6

[0079] S310: acquiring a second touch feature parameter in response to a moving operation of the teaching aid contacting the touch device;

[0080] S320: adjusting the shape of the virtual teaching aid according to the second touch feature parameter, and displaying the adjusted virtual teaching aid on the display interface.

[0081] ​​The moving operation includes, but is not limited to, moving the position and angle of the teaching aid, etc.

[0082] The second touch feature parameter is touch data generated by the teaching aid contacting the touch device after the user moves the teaching aid.

[0083] In another embodiment, the latest touch data can also be acquired by timing, and the virtual teaching aid is adjusted and displayed in real time according to the latest touch data, so as to ensure that the virtual teaching aid is always consistent with the real teaching aid and improve the user teaching experience.

[0084] When the adjusted virtual teaching aid is displayed, the moving process of the virtual teaching aid following the moving operation can be displayed on the display interface, or the virtual teaching aid at the position and angle after the teaching aid is stopped can also be displayed.

[0085] In the embodiment of the application, after the virtual teaching aid is generated and displayed, the user can quickly adjust the shape and angle of the generated virtual teaching aid by moving the teaching aid, so as to ensure that the generated virtual teaching aid is always consistent with the real teaching aid, and the user does not need to perform complicated operations during the adjustment process, which can effectively improve the user experience.

[0086] The virtual teaching aid display method of the application can automatically convert the real teaching aid into a virtual teaching aid that can be used on a computer or a mobile device, improving the teaching interest; meanwhile, the application can realize displacement, rotation, enlargement and reduction of the virtual teaching aid by moving and pressing the real teaching aid, which is more convenient and humanized in operation, and can reduce the learning cost of the teacher operating the virtual teaching aid.
