Detailed Description
For the purposes of making the objects, technical solutions and advantages of the embodiments of the present disclosure more apparent, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below, and it is apparent that the described embodiments are some embodiments of the present disclosure, but not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the disclosure, are within the scope of the disclosure.
The touch position identification method provided by the application can be applied to an application environment shown in fig. 1. The touch position recognition method is applied to a touch position recognition system. The touch location recognition system includes a stylus 101, a device to be touched 102, and a location data determining component 103 of a touch location communicatively coupled to the stylus 101. Wherein the stylus 101 includes an infrared signal transmitting module 1011 and an infrared signal receiving module 1012; in use, the infrared signal transmission module 1011 transmits infrared information in both a first direction and a 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 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 clicking, sliding, etc. operations 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 in this way can the probability of false touches be reduced. Illustratively, the stylus 101 is a pen-shaped device, or the stylus 101 is a finger ring-shaped device.
The touch pen is used for acquiring a first reflection signal formed when the touch pen clicks the touch area. Specifically, the infrared signal receiving module 1012 in the stylus is configured to obtain a first reflected signal formed when the stylus clicks the touch area. And the position data determining component is used for determining the position data of the clicking position of the touch pen based on the first reflected 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 the device to be touched; but may also be integrated in other electronic devices.
If the position data determining component of the touch position is integrated in the touch pen, when performing touch operation, a user clicks a certain position in the touch area of the device to be touched 102 by using the touch pen 101 as required, the touch pen 101 emits infrared signals along a first direction and a second direction, and the infrared signals are reflected by the shielding object to form a first reflection signal. The stylus 101 acquires the first reflected signal; position data of the stylus click 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 an operation 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 emits infrared signals along a first direction and a second direction, and the infrared signals are reflected by a shielding object to form a first reflection signal. The stylus 101 obtains the first reflected signal, and transmits the first reflected signal to the device to be touched 102, and the device to be touched 102 determines position data of a clicking position of the stylus based on the first reflected signal. Optionally, the stylus 101 communicates with the device to be touched 102 through bluetooth technology or wifi technology, etc.
If the location data determining component of the touch location is integrated in other electronic devices, the device to be touched 102 may or may not have an operation 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 emits infrared signals along a first direction and a second direction, and the infrared signals are reflected by a shielding object to form a first reflection signal. The stylus 101 acquires the first reflected signal, transmits the first reflected signal to other electronic devices, and a position data determining component of a touch position in the other electronic devices determines position data of a click position of the stylus 101 based on the first reflected signal. Optionally, the stylus 101 communicates with other electronic devices through bluetooth technology or wifi technology. This situation is similar to using a mouse to move a click on a desktop to control the effect of a computer. Specifically, the stylus 101 resembles a mouse, the other electronic devices resemble a computer, and the device to be touched 102 resembles a desktop for supporting and providing a plane for the mouse.
If the to-be-touched device 102 has the computing capability, it may be further configured that the to-be-touched device 102 also has the display capability. If the to-be-touched device 102 has a display capability, the to-be-touched device 102 may be a television, a smart phone, a portable wearable device, a computer, etc.
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 recognition method according to an embodiment of the disclosure. In this embodiment, the position data determining component of the touch position is integrated in the device to be touched for illustration. The method is applied to the touch position recognition system in fig. 1 for illustration. Referring to fig. 2, the touch position recognition method includes:
s201, when a touch pen clicks a touch area, a first reflection signal is formed.
The specific implementation method of the step is various, when designing the stylus, a touch control main 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 equipment to be touched or slides on the equipment to be touched, the tip is in a pressing state, and at the moment, the infrared signal emitting module starts to emit infrared signals. The infrared signal is reflected by the shielding object to form a first reflected signal. The infrared signal receiving module starts to receive the first reflected signal and transmits the first reflected signal to the to-be-touched device in real time.
The shielding object is used for enabling infrared signals emitted by the touch pen infrared signal emitting module to be reflected. In practice, an object that can cause an infrared signal to be reflected can act as a shutter. Illustratively, the covering may be a wall, roof, bezel of a display screen, or the like.
S202, determining position data of a clicking position of the touch pen based on the first reflected signal.
The position data of the clicking position of the stylus refers to data capable of specifically indicating the relative position relationship between the clicking position of the stylus and the touch area. Illustratively, the position data of the stylus click position includes a distance of the stylus click position from a boundary of the touch area.
The technical scheme is that the touch 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 the first direction and the second direction; the infrared signal receiving module can receive the reflected signal of the 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; based on the first reflected signal, position data of the clicking position of the touch pen is determined, and as the infrared signal has a ranging function, the essence of the technical scheme is that the position of the clicking position of the touch pen in space is detected by utilizing the infrared signal transmitting module and the infrared signal receiving module which are arranged on the touch pen, so that the identification of the touch position is realized. The realization of the touch position recognition method can realize the purpose of interacting with the equipment which does not originally have a touch function in a touch manner without structural transformation of the equipment to be touched, and can improve the user experience.
The technical scheme can also provide an alternative touch position recognition mode for the touch screen, and can cope with the situations of failure of the touch screen and the like.
The technical scheme has wide application prospect, and the three reasons are that whether the equipment to be touched has operation capability or not can be subjected to touch position identification, so that in practice, an object with a proper size can be selected as the equipment to be touched according to the requirement, and touch operation is completed; secondly, because in above-mentioned technical scheme, infrared signal transmitting module and infrared signal receiving module install on the stylus, carry out the distance inspection, but it is not restricted by touch area size. The touch position identification can be realized no matter how large the touch area is; thirdly, the realization of the touch position recognition by the technical scheme is mainly based on the cooperation of the touch pen and software, so that the portable touch position recognition device is good in portability and low in cost.
In one embodiment, optionally, the touch location identifying method further includes: determining position data of a boundary line of a touch area; determining position data of a click position of the stylus based on the first reflected signal, comprising: and determining the position data of the clicking position of the touch pen based on the first reflected 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, position data of a boundary line of the touch area are determined.
The purpose of this step is to build a spatial model of the touch area, or to specify 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 the step is various, and the second reflection signal formed in the process that the touch pen moves for one circle along the boundary line of the touch area is obtained by way of example; and determining position data of the boundary line of the touch area based on the second reflection signal.
Specifically, the stylus acquires a second reflected signal formed during one revolution of the stylus along the boundary line of the touch area. The to-be-touched device determines the distance from each point on the boundary line of the touch area to the shielding object based on the second reflected signal; and determining 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 shielding objects, the first direction is the X direction, and the second direction is the Y direction. In practice, the covering may be a roof or wall or the like. It can be understood by those skilled in the art that the boundary line of the touch area can be regarded as a set of points, and that the stylus moves one circle along the boundary line of the touch area, which means that ranging is performed at each point on the boundary line, so that a ranging result of each point of the boundary line from the shielding object can be obtained, and further, position data of the boundary line in space can be obtained. This method can ensure that the obtained positional data of the boundary line is accurate. This method is particularly applicable to the case where the shape of the touch area is non-polygonal.
Or if the shape of the touch area is polygonal, the specific implementation method of the step may further include: acquiring a third reflection signal formed at the vertex of the polygon clicked by the stylus; based on the third reflected signal, position data of a touch area boundary line is determined.
Specifically, the stylus acquires a third reflected signal formed at the vertex of the polygon that the stylus clicks on. The device to be touched determines the distance between each vertex of the polygon and the shielding object based on the third reflection signal; and determining position data of the boundary line of the touch area based on the distances from the vertexes of the polygon to the shielding object.
With continued reference to fig. 4, since the shape of the touch area is a quadrilateral, only the third reflection signals formed at the four vertices of the quadrilateral are obtained, so as to obtain the position data of the boundary line of the touch area. Obviously, the method has fewer points requiring ranging, smaller calculation amount and faster execution speed.
S302, when a touch area is clicked by a touch pen, a first reflection signal is formed.
S303, determining position data of a clicking position of the stylus 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 shielding object; when the step is executed, the device to be touched determines the distance from the clicking position of the stylus to the shielding object based on the first reflection signal, and then determines the position data of the clicking position of the stylus based on the distance from the clicking position of the stylus to the shielding object and the distance from the boundary line of the touch area to the shielding object. Specifically, the difference between the distance from the clicking position of the stylus to the shielding object and the distance from the boundary line of the touch area to the shielding object can be used as the position data of the clicking position of the stylus 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 of the touch area B is parallel to the shielding object C1, and the distance from the shielding object C1 is y1; the left line of the touch area B is parallel to the shielding object C2, and the distance from the shielding object C2 is x1. In S302, the stylus clicks on point M of the touch area B to form a first reflected signal. When S303 is performed, based on the first reflected signal, the M point is at a distance y2 from the obstruction C1, and at a distance x2 from the obstruction C2. Further, by combining the position data of the boundary line of the touch area B, it can be determined that the distance between the M point and the upper boundary line of the touch area B is y0=y2-y 1, and the distance between the M point and the left boundary line of the touch area B is x0=x2-x 1. The coordinates of the M point can thus 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 except the display area (such as a non-display area surrounding the display area) do not need to have the touch function. By determining the position data of the boundary line of the touch area, the position data is configured substantially before touch, so that an execution body (such as a device to be touched) for executing the technical scheme provided by the disclosure determines which area is used as the touch area.
It should be noted that, in practice, if the position and/or posture of the to-be-touched device relative to the shielding object changes, the step S301 needs to be executed again.
On the basis of the technical scheme, optionally, the device to be touched further comprises a display area, wherein the touch area is positioned in the display area, and the area of the touch area is smaller than that of the display area; the touch position identification method further comprises the following steps: determining position data of a boundary line of the display area; determining position data of a click position of the stylus based on the first reflected signal, comprising: position data of a click position of the stylus is determined based on the first reflected signal and position data of a boundary line of the display area. Specifically, as shown in fig. 5, the touch position recognition includes:
s401, position data of a boundary line of the touch area are determined.
S402, position data of a boundary line of a display area are determined.
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 the 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 by way of example; position data of a boundary line of the display area is determined based on the fourth reflection signal.
Alternatively, the display area is polygonal in shape; the specific implementation method of the steps comprises the following steps: acquiring a fifth reflected signal formed at the vertex of the polygon clicked by the stylus; position data of a boundary line of the display area is determined based on the fifth reflected signal.
S403, when the touch pen clicks the touch area, a first reflection signal is formed.
S404, determining position data of a clicking position of the stylus 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 includes a distance of the boundary line of the display area from the obstacle; when the step is executed, the device to be touched determines the distance from the clicking position of the touch pen to the shielding object and the distance from the boundary line of the display area to the shielding object based on the first reflection signal, and determines the position data of the clicking position of the touch pen. Specifically, the difference between the distance from the clicking position of the stylus to the shielding object and the distance from the boundary line of the display area to the shielding object can be used as the position data of the clicking position of the stylus 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 the area of the display area D. C1 and C2 are both shutters. The arrangement can realize that only the local area of the display area has a touch function, and other parts do not have the purpose of the touch function, so that diversified use requirements can be met.
In practice, as shown in fig. 7, the non-display area N and the display area D may form a "concave" shape when viewed from the side. Specifically, in a direction perpendicular to the display surface, at an intersection line of 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 emitting module and the infrared signal receiving module of the stylus pen F are low, as shown in fig. 7, the structure forming the non-display area N serves as a shielding object, so that the infrared signal P is reflected. This case may not be performed S402 to simplify the calculation process of the touch position recognition method.
On the basis of the above embodiments, optionally, the touch position identifying method further includes; judging whether the clicking position of the current touch pen is positioned in a touch area or not; if yes, performing touch response based on the position data of the clicking position of the touch pen.
The touch response means that the next operation is executed according to the content corresponding to the clicking position of the touch pen. For example, if a dialog box asking the user "whether to restart the device" is displayed in the screen. If yes is detected to be displayed at the clicking position of the touch control pen, restarting the device.
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, these steps are not necessarily performed in order as indicated by the arrows.
