Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. The terms "comprising," "including," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.
[0048] The screen touch control method provided in this application embodiment can be applied to various scenarios that require screen control. In this application embodiment, the screen can be a large touch screen device, which can be composed of several sub-screens.
[0049] The screen touch control method provided in this application can be executed by a screen control device. This control device can be connected to the screen, and it can also be connected to various ranging sensors. When a user needs to control the screen, they can execute the various steps of the screen touch control method provided in this application through the control device, thereby enabling more convenient screen control.
[0050] Please refer to Figure 1, which is a flowchart of the implementation of the screen touch method provided in the embodiment of this application. The screen touch method provided in the embodiment of this application may include steps S101 to S103, which are described in detail below:
[0051] In S101, several ranging sensors are used to acquire the first distance data between the target object in the preset touch space and each ranging sensor.
[0052] The ranging sensor can be used to acquire first distance data between a target object within a preset touch space and the ranging sensor. For example, the ranging sensor can be a Time of Flight (TOF) ranging sensor.
[0053] Each time-of-flight ranging sensor can acquire initial distance data in the following ways:
[0054] The time-of-flight ranging sensor may include a photonic signal transmitter and a photonic signal receiver. Based on this, the time-of-flight ranging sensor can emit photonic signals to a target object within a preset touch space through the photonic signal transmitter. After the photonic signal flies to the target object, it will be reflected by the target object and thus received by the photonic signal receiver. Based on this, by obtaining the first time when the photonic signal is emitted by the photonic signal transmitter and the second time when the photonic signal is received by the photonic signal receiver, the time difference between the first time and the second time can be obtained, and then the first distance data can be determined by the time difference between the first time and the second time.
[0055] Each ranging sensor can be positioned at a preset location, which is fixed relative to the screen. In an alternative implementation, each ranging sensor can be positioned at a fixed location on the screen; for example, each ranging sensor can be positioned at the edge of the casing on the screen.
[0056] In this embodiment, the number of ranging sensors can be three. This allows for better positioning of the target object by measuring the distance between the sensor and the target. The number of ranging sensors can also be set according to actual needs, for example, more than three; this is not limited here.
[0057] The preset touch space can be a virtual space determined based on the performance and parameters of each ranging sensor. When the target object is within the touch space, each ranging sensor can acquire first distance data relative to the target object and send this data to the control device. This allows the control device to acquire the first distance data between the target object and each ranging sensor within the preset touch space. When the target object is not within the touch space, the ranging sensors may not be able to acquire the first distance data relative to the target object.
[0058] The target object can be the user's hand or a stylus, etc. The user can control the screen by placing the target object at a target location within the touch space, or by moving the target object within the touch space.
[0059] Please refer to Figure 2, which is a schematic diagram of an example of a target object controlling the screen within a touch space according to an embodiment of this application. As shown in Figure 2, the user can use their hand to draw "ABCD" at a target location within the touch space. At this time, each distance sensor will acquire the first distance data between the hand and each distance sensor at each moment. Furthermore, in Figure 2, the touch space can be a cuboid-shaped space in front of the screen.
[0060] In this embodiment of the application, the control device can obtain the first distance data between the target object in the preset touch space and the distance sensor for each distance sensor, thereby obtaining the first distance data between the target object in the preset touch space and each distance sensor.
[0061] In one possible implementation, each ranging sensor may include a Fresnel lens, and the Fresnel lens in each ranging sensor may be connected to a control device. The control device can change the touch space by controlling the angle of the Fresnel lens in each ranging sensor.
[0062] In S102, the target touch point on the screen is determined based on each first distance data.
[0063] The relative positions of the screen and several ranging sensors are fixed.
[0064] In this embodiment of the application, after the control device acquires the first distance data between the target object and each ranging sensor, the control device can determine the target touch point on the screen based on each first distance data.
[0065] In one possible implementation, the control device can first obtain the first correspondence between each first distance data and each touch point on the screen, and then determine the target contact point based on each first distance data and the first correspondence.
[0066] The first correspondence includes the first distance data corresponding to each contact point on the screen. It should be noted that, since the touch space in this embodiment includes multiple contact planes, each contact point corresponds to multiple corresponding points on multiple contact planes, and the multiple first distance data corresponding to each corresponding point on each contact plane are different. Therefore, in this embodiment, each contact point can correspond to multiple first distance data.
[0067] In one possible implementation, the control device can determine the first correspondence through steps a to c, as detailed below:
[0068] In step a, the screen is divided into several first regions according to the preset positioning accuracy, and the touch space is divided into several parallel touch planes.
[0069] In this implementation, the control device can pre-divide the screen into several first regions according to a preset positioning accuracy. Please refer to Figure 3, which is a schematic diagram of an example of dividing the screen into several first regions according to an embodiment of this application. As shown in Figure 3, when the screen is rectangular, the control device can divide the screen into several small rectangles of the same size as second regions.
[0070] Furthermore, the control device can pre-divide the touch space into several parallel touch planes according to a preset positioning accuracy. Please refer to Figure 4, which is a schematic diagram of an example of dividing the touch space into several parallel touch planes according to an embodiment of this application. As shown in Figure 4, a touch plane can be divided into the touch space at preset distances. It should be noted that the shape of the touch plane is the same as the shape of the screen, but the length and width of the touch plane can be different from the length and width of the screen. In addition, the various touch planes can be parallel to each other.
[0071] In step b, for each touch plane, the touch plane is divided into several second regions, and a second correspondence between each second region and each first region is determined; for each second region of the touch plane, a second distance data of the training object when touching the second region is obtained by several ranging sensors.
[0072] In this implementation, after dividing the first region and the touch plane, the control device can divide each touch plane into several second regions and determine a second correspondence between each second region and each first region. In this second correspondence, one second region can correspond to one first region.
[0073] Specifically, the control device can divide the touch plane into several second regions based on the characteristics of the target object and the training object. For example, when the target object and the training object are fingers, the touch plane can be divided into several second regions based on the width of the fingers.
[0074] It should be noted that the number of each first area can be the same as the number of each second area, and there is a one-to-one correspondence between each second area and each first area. The shape of each first area is the same as the shape of each second area. However, when the length and width of the touch plane are different from the length and width of the screen, the length and width of the first area are also different from the length and width of the second area.
[0075] After dividing the touch plane into several second regions, the control device can also use several ranging sensors to acquire second distance data of the training object when touching the second region for each second region of the touch plane.
[0076] Specifically, users can use a training object to touch each second area of the touch plane, and after each second area is touched, several ranging sensors will acquire the second distance data of the training object when touching the second area, thereby obtaining the second distance data corresponding to each second area in the touch plane.
[0077] The above method can be applied to each touch plane to obtain the second distance data corresponding to each second region in each touch plane.
[0078] It should be noted that the training object can be the user's hand or a stylus. The difference between the training object and the target object is that the training object is used to enable the control device to acquire the second distance data corresponding to each second area in each touch plane, while the target object is used to be placed or moved within the touch space so that the control device can acquire the first distance data between the target object and each ranging sensor.
[0079] In step c, the first correspondence is determined based on the second distance data corresponding to each second region on each touch plane and the second correspondence.
[0080] In this implementation, after the control device determines the second correspondence between each second region and each first region, and obtains the second distance data corresponding to each second region on each touch plane, the control device can determine the first correspondence based on the second distance data corresponding to each second region on each touch plane and the second correspondence.
[0081] Specifically, the control device can determine the corresponding first region for each second region on each touch plane according to a second correspondence relationship, and determine the sub-correspondence relationship of the second region based on the first region corresponding to the second region and the second distance data corresponding to the second region. It should be noted that each first region corresponds to one contact point.
[0082] Since the second distance data obtained above are obtained by training the object to touch the second area on each touch plane, in actual applications, the target object may not touch each touch plane very accurately, but may touch the boundary between each touch plane.
[0083] Based on this, in one possible implementation, the sub-correspondence of any second region can be determined through steps d to f, as detailed below:
[0084] In step d, the error range is determined based on the distance between each touch plane.
[0085] In this implementation, the control device can determine the error range based on the distance between each touch surface.
[0086] In practical applications, the relationship between the distance between each touch plane and the error range can be determined based on the pre-trained error range prediction model stored in the control device. Specifically, the error range prediction model can be trained using a deep learning algorithm. The distance between each touch plane can then be input into the error range prediction model to instruct it to output the error range based on the distance between each touch plane, thus allowing the control device to obtain the error range.
[0087] In step e, the distance data range corresponding to the second region is determined based on the second distance data and the error range corresponding to the second region.
[0088] In this implementation, after determining the error range, the control device can determine the distance data range corresponding to the second region based on the second distance data corresponding to the second region and the error range.
[0089] In step f, the sub-correspondence relationship of the second region is determined based on the first region corresponding to the second region and the distance data range corresponding to the second region.
[0090] In this implementation, after determining the distance data range corresponding to the second region, the control device can determine the sub-correspondence relationship of the second region based on the first region corresponding to the second region and the distance data range corresponding to the second region.
[0091] By using the above methods, the sub-correspondence of each second region can be determined, thereby accurately determining the target contact point when the target object touches the boundary between each touch plane, thus improving the accuracy of touch.
[0092] By using the above method, the sub-correspondence relationship of each second region is obtained. Then, the control device can determine the first correspondence relationship based on the sub-correspondence relationship of each second region on each touch plane.
[0093] Taking the second region S1 on the touch plane Q1 as an example, the control device can determine the first region S2 corresponding to the second region S1 based on the second correspondence. Since the touch point corresponding to the first region S2 is S3, the control device can obtain that the touch point corresponding to the second distance data of the second region S1 is S3, thus obtaining the sub-correspondence corresponding to the second region S1. Applying the above method to each second region of each touch plane, the sub-correspondence corresponding to each second region can be obtained, and then the first correspondence can be obtained.
[0094] The control device can pre-store a first correspondence relationship, so that after acquiring each first distance data, it can determine the target touch point based on each first distance data and the first correspondence relationship.
[0095] In S103, the screen is controlled based on the target touch point.
[0096] In this embodiment of the application, after the target touch point is determined, the control device can control the screen according to the target touch point.
[0097] In practical applications, the specific method by which the control device controls the screen based on the target touch point can be set according to actual needs, and is not limited here.
[0098] As can be seen from the above, the screen touch control method provided in this application embodiment can be applied to screen control devices. Specifically, it includes: firstly, acquiring first distance data between a target object within a preset touch space and each distance sensor using several distance sensors; then, determining a target touch point on the screen based on the first distance data; fixing the relative position of the screen and the several distance sensors; and finally, controlling the screen based on the target touch point. Using this method, users can control the screen remotely within a preset touch space using their hand or a stylus, thus eliminating the need for physical contact or a handheld controller, improving the convenience of screen control.
