Detailed Description
To make the objects, technical solutions and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below, and it is obvious that the described embodiments are some embodiments of the present disclosure, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments disclosed herein without making any creative effort, shall fall within the protection scope of the present disclosure.
The touch position identification method provided by the application can be applied to the application environment shown in fig. 1. The touch position identification method is applied to a touch position identification system. The touch position identification system comprises a stylus 101, a device to be touched 102 and a position data determination component 103 of a touch position in communication connection with the stylus 101. The stylus 101 includes an infrared signal transmitting module 1011 and an infrared signal receiving module 1012; when the infrared signal transmitting module 1011 is used, infrared information is transmitted along the first direction and the second direction; the infrared signal receiving module 1012 can receive a reflected signal of the infrared signal; the device to be touched 102 includes a touch area. The first direction and the second direction are crossed, and the first direction and the second direction are both parallel to the touch area. Optionally, the first direction and the second direction are perpendicular.
The stylus 101 should be understood as a device having a tip capable of performing a click, slide, etc. operation in a small area. This is because, in use, the user clicks the touch area of the device to be touched 102 with the tip of the stylus 101 as needed to complete the touch operation. Only then can the chance of a false touch be reduced. Illustratively, stylus 101 is a pen-shaped device, or stylus 101 is a ring-shaped device.
The touch control pen is used for acquiring a first reflection signal formed when the touch control pen clicks the touch control area. Specifically, the infrared signal receiving module 1012 in the stylus is configured to obtain a first reflection signal formed when the stylus clicks the touch area. And the position data determining component of the touch position is used for determining the position data of the click position of the stylus based on the first reflection signal.
In practice, the position data determining component of the touch position may be integrated in the stylus; the touch control device can also be integrated in equipment to be touched; but also integrated in other electronic devices.
If the position data determining component of the touch position is integrated in the stylus, when performing touch operation, a user clicks a certain position in the touch area of the device 102 to be touched by using the stylus 101 as required, the stylus 101 transmits infrared signals along both the first direction and the second direction, and the infrared signals are reflected by the shielding object to form a first reflection signal. The stylus 101 acquires the first reflection signal; position data for the stylus tap position is then determined based on the first reflected signal.
If the position data determining component of the touch position is integrated in the device to be touched, the device to be touched 102 needs to have the computing capability. When performing touch operation, a user clicks a certain position in a touch area of the device to be touched 102 by using the stylus 101 as required, the stylus 101 transmits infrared signals along both the first direction and the second direction, and the infrared signals are reflected by the shielding object to form a first reflection signal. The stylus 101 acquires the first reflection signal, transmits the first reflection signal to the device to be touched 102, and the device to be touched 102 determines position data of a click position of the stylus based on the first reflection signal. Optionally, the stylus 101 and the device to be touched 102 communicate through bluetooth technology or wifi technology.
If the position data determining component of the touch position is integrated in other electronic devices, the device to be touched 102 may or may not have a computing capability. When performing touch operation, a user clicks a certain position in a touch area of the device to be touched 102 by using the stylus 101 as required, the stylus 101 transmits infrared signals along both the first direction and the second direction, and the infrared signals are reflected by the shielding object to form a first reflection signal. The stylus 101 acquires the first reflection signal, and transmits the first reflection signal to the other electronic device, and the position data determining component of the touch position in the other electronic device determines the position data of the click position of the stylus 101 based on the first reflection signal. Optionally, the stylus 101 communicates with other electronic devices via bluetooth technology or wifi technology. This situation is similar to the effect of using a mouse to move a click on a desktop to control a computer. Specifically, the stylus 101 is similar to a mouse, the other electronic devices are similar to computers, and the device to be touched 102 is similar to a desktop for supporting and providing a flat surface for the mouse.
If the device to be touch-controlled 102 has the computing capability, the device to be touch-controlled 102 may further have a display capability. If the device to be touched 102 has a display capability, the device to be touched 102 may be a television, a smart phone, a portable wearable device, a computer, or the like.
If the device to be touched 102 does not have the computing capability, the device to be touched 102 may be a desktop, a curtain, a blackboard, or the like.
The other electronic devices may be televisions, smart phones, portable wearable devices, computers, and the like.
Fig. 2 is a flowchart of a touch position identification method according to an embodiment of the disclosure. The present embodiment mainly takes the case that the position data determining component of the touch position is integrated in the device to be touched as an example. The method is applied to the touch position recognition system in fig. 1 for illustration. Referring to fig. 2, the touch position identifying method includes:
s201, a first reflection signal formed when the touch pen clicks the touch area is obtained.
The specific implementation method of the step is various, when the touch pen is designed, the touch master switch can be designed at the position of the tip, and the infrared signal transmitting module and the infrared signal receiving module are both designed at the position close to the tip. When the tip clicks the device to be touched or slides on the device to be touched, the tip is in a pressing state, and the infrared signal transmitting module starts to transmit an infrared signal at the moment. The infrared signal is reflected by the shielding object to form a first reflection signal. The infrared signal receiving module starts to receive the first reflection signal and transmits the first reflection signal to the device to be touched in real time.
The function of the shielding object is to enable the infrared signal emitted by the touch pen infrared signal emitting module to be reflected. In practice, an object that enables the infrared signal to be reflected may act as a shield. Illustratively, the barrier may be a wall, a roof, a bezel of a display screen, and the like.
S202, determining position data of the touch pen clicking position based on the first reflection signal.
The position data of the touch position of the stylus refers to data that can specifically indicate a relative position relationship between the touch position of the stylus and the touch area. Illustratively, the location data for the stylus tap location includes a distance of the stylus tap location from a boundary of the touch area.
According to the technical scheme, the touch control pen comprises an infrared signal transmitting module and an infrared signal receiving module; when the infrared signal transmitting module is used, the infrared signal transmitting module transmits infrared information along a first direction and a second direction; the infrared signal receiving module can receive a reflected signal of an infrared signal; the device to be touched comprises a touch area; the touch position identification method comprises the following steps: acquiring a first reflection signal formed when a touch pen clicks a touch area; the method comprises the steps of determining position data of a touch pen clicking position based on a first reflection signal, and detecting the position of the touch pen clicking position in a space by utilizing an infrared signal transmitting module and an infrared signal receiving module which are installed on the touch pen due to the fact that the infrared signal has a distance measuring function, so that the touch position is identified. The touch position identification method can realize the purpose of interacting with equipment which does not have a touch function originally in a touch mode without carrying out structural transformation on the equipment to be touched, and can improve user experience.
The technical scheme can also provide an alternative touch position identification mode for the touch screen, and can deal with the conditions of failure of the touch screen and the like.
The technical scheme has wide application prospect for three reasons, firstly, no matter whether the equipment to be touched has the operational capability or not, the touch position can be identified, so that in practice, an object with a proper size can be selected as the equipment to be touched to complete touch operation; secondly, because in the above technical scheme, the infrared signal transmitting module and the infrared signal receiving module are installed on the touch pen for distance check, it is not limited by the size of the touch area. Touch position identification can be realized no matter the size of the touch area; thirdly, because the realization of the touch position identification of the technical scheme mainly depends on the cooperation of the touch pen and the software, the portability is good, and the cost is low.
In one embodiment, optionally, the touch position identification method further includes: determining position data of a boundary line of a touch area; determining position data for a stylus tap position based on the first reflected signal, comprising: and determining the position data of the clicking position of the touch pen based on the first reflection signal and the position data of the boundary line of the touch area. Specifically, as shown in fig. 3, the touch position recognition includes:
s301, determining position data of a boundary line of the touch area.
The purpose of this step is to establish a spatial model of the touch area, or to define the position of the touch area in space.
Specifically, the device to be touched determines position data of a boundary line of the touch area.
The specific implementation method of this step is various, and exemplarily, a second reflection signal formed in the process that the stylus pen moves for one circle along the boundary line of the touch area is obtained; and determining position data of the boundary line of the touch area based on the second reflection signal.
Specifically, the stylus acquires a second reflection signal formed during the movement of the stylus along the boundary line of the touch area by one circle. Determining the distance from each point on the boundary line of the touch area to the shielding object by the touch equipment based on the second reflection signal; and determining the position data of the boundary line of the touch area based on the distance from each point on the boundary line of the touch area to the shielding object.
For example, referring to fig. 4, a is a device to be touched, B is a touch area of the device to be touched, C1 and C2 are both blinds, the first direction is an X direction, and the second direction is a Y direction. In practice, the shade may be a roof or wall or the like. Those skilled in the art can understand that the border line of the touch area can be regarded as a set of points, and the movement of the stylus along the border line of the touch area by one circle means that distance measurement is performed at each point on the border line, so that the distance measurement result from each point of the border line to the obstacle can be obtained, and further the position data of the border line in the space can be obtained. This method can ensure that the obtained position data of the boundary line is accurate. This method is particularly suitable for the case where the shape of the touch area is non-polygonal.
Or, if the shape of the touch area is a polygon, the specific implementation method of this step may further include: acquiring a third reflection signal formed at the vertex of the polygon clicked by the stylus; and determining position data of the boundary line of the touch area based on the third reflection signal.
Specifically, the stylus acquires a third reflection signal formed at a vertex of the stylus-clicking polygon. Determining the distance from each vertex of the polygon to the shielding object by the to-be-touched equipment based on the third reflection signal; and determining position data of the boundary line of the touch area based on the distances from all vertexes of the polygon to the shielding object.
With reference to fig. 4, since the touch area is quadrilateral, only the third reflection signals formed at the four vertices of the quadrilateral are obtained, and the position data of the boundary line of the touch area is obtained. Obviously, the method needs fewer points for ranging, has less calculation amount and is faster in execution speed.
S302, a first reflection signal formed when the touch pen clicks the touch area is obtained.
And S303, determining the position data of the click position of the touch pen based on the first reflection signal and the position data of the boundary line of the touch area.
Optionally, the position data of the touch area boundary line includes a distance from the touch area boundary line to the obstacle; when the step is executed, the to-be-touched device determines the distance from the touch pen clicking position to the shielding object based on the first reflection signal, and then the to-be-touched device determines the position data of the touch pen clicking position based on the distance from the touch pen clicking position to the shielding object and the distance from the touch area boundary line to the shielding object. Specifically, the difference between the distance from the touch pen click position to the blocking object and the distance from the touch area boundary line to the blocking object may be used as the position data of the touch pen click position for the device to be touched.
With continued reference to fig. 4, it is assumed that after S301, the position data of the boundary line of the touch area B includes: the upper edge line of the touch area B is parallel to the shade C1, and the distance from the shade C1 is y 1; the left edge of the touch area B is parallel to the shade C2, and is spaced from the shade C2 by x 1. In S302, the stylus pen clicks M points of the touch area B to form a first reflection signal. In performing S303, based on the first reflected signal, it can be found that the M point is a distance y2 from the shade C1 and a distance x2 from the shade C2. Further combining the position data of the boundary line of the touch area B, it may be determined that the distance from the M point to the upper line of the touch area B is y 0-y 2-y1, and the distance from the M point to the left line of the touch area B is x 0-x 2-x 1. Whereby the coordinates of the M points can be uniquely determined.
Since the area available as the touch area is limited in practice, for example, if the device to be touched is a television, only the display area of the television needs to have the touch function, and other areas (such as a non-display area surrounding the display area) except the display area do not need to have the touch function. By determining the position data of the touch area boundary line, the essence is that the position data is configured before touch, so that an executing body (such as a device to be touched) for executing the technical scheme provided by the present disclosure specifies which area is used as the touch area.
It should be noted that, in practice, if the position and/or the posture of the device to be touched relative to the barrier changes, the step S301 needs to be executed again.
On the basis of the above technical solution, optionally, the device to be touch-controlled further includes a display area, the touch-control area is located in the display area, and the area of the touch-control area is smaller than the area of the display area; the touch position identification method further comprises the following steps: determining position data of a boundary line of a display area; determining position data for a stylus tap position based on the first reflected signal, comprising: and determining position data of the clicking position of the touch pen based on the first reflection signal and the position data of the boundary line of the display area. Specifically, as shown in fig. 5, the touch position recognition includes:
s401, determining position data of a boundary line of the touch area.
S402, determining position data of the boundary line of the display area.
Specifically, the device to be touched determines position data of a boundary line of the display area.
The specific implementation method of the step is various, and exemplarily, a fourth reflection signal formed in the process that the touch pen moves for one circle along the boundary line of the display area is obtained; based on the fourth reflection signal, position data of the display area boundary line is determined.
Or the shape of the display area is a polygon; the specific implementation method of the step comprises the following steps: acquiring a fifth reflection signal formed at the vertex of the polygon clicked by the stylus; based on the fifth reflection signal, position data of the display region boundary line is determined.
S403, acquiring a first reflection signal formed when the touch pen clicks the touch area.
S404, determining position data of the touch pen clicking position based on the first reflection signal and the position data of the boundary line of the display area.
Optionally, the position data of the boundary line of the display area comprises a distance from the boundary line of the display area to the obstruction; when the step is executed, the device to be touched determines the distance from the touch pen clicking position to the shielding object and the distance from the display area boundary line to the shielding object based on the first reflection signal, and determines the position data of the touch pen clicking position. Specifically, the difference between the distance from the touch pen click position to the blocking object and the distance from the display area boundary line to the blocking object may be used as the position data of the touch pen click position for the device to be touched.
Referring to fig. 6, assume that a is a device to be touched, B is a touch area of the device to be touched, D is a display area of the device to be touched, the touch area B is located within the display area D, and the area of the touch area B is smaller than that of the display area D. C1 and C2 are both shades. The touch control function can be realized only in the partial area of the display area, and the touch control function is not realized in other parts, so that diversified use requirements can be met.
In practice, as shown in fig. 7, the non-display region N and the display region D may be formed in a concave shape when viewed from the side. Specifically, in the direction perpendicular to the display surface, at the boundary line between the display area D of the device to be touched and the non-display area N surrounding the display area D, the non-display area N is higher than the display area D. In this case, if the installation positions of the infrared signal transmitting module and the infrared signal receiving module of the stylus F are both low, the situation as shown in fig. 7 may occur, and the structure constituting the non-display area N serves as a barrier, so that the infrared signal P is reflected. In this case, S402 may not be performed to simplify the calculation process of the touch position recognition method.
On the basis of the foregoing embodiments, optionally, the touch position identification method further includes; judging whether the current touch pen clicking position is located in the touch area; and if so, performing touch response based on the position data of the click position of the stylus.
And performing touch response, namely executing the next operation according to the content corresponding to the click position of the touch pen. Illustratively, if a dialog box asking the user whether to restart the device is displayed in the screen. And if yes is detected to be displayed at the touch pen clicking position, restarting the equipment.
It should be understood that although the steps in the flowcharts of fig. 2, 3 and 5 are shown in order as indicated by the arrows, the steps are not necessarily performed in order as indicated by the arrows.
