Fig. 2 is a schematic structural diagram of a stylus without a reflection function, as shown in fig. 2, the stylus includes a body 9 and a tip 10, and the tip 10 contacts with a touch panel to input information. Wherein, this nib 10 can shelter from the infrared signal that first infrared emitter 1 and second infrared emitter 2 sent.

As shown in fig. 3, the touch pen includes a pen body 11 and a pen head 12, wherein a four-sided mirror reflection device 13 is disposed on the pen head 12, and the four-sided mirror reflection device 13 can reflect infrared signals emitted by the first infrared emitter 1 and the second infrared emitter 2.
As shown in fig. 4, the touch pen includes a pen body 11 and a pen point 12, wherein the pen point 12 is provided with a four-sided specular reflection device 14, the four-sided specular reflection device 14 has a different specific structure from the four-sided specular reflection device 13 shown in fig. 3, the four-sided specular reflection device 14 can also reflect the infrared signals emitted by the first infrared emitter 1 and the second infrared emitter 2, and the reflection angle of the infrared signals is different from the reflection angle of the four-sided specular reflection device 13 to the infrared signals.

In the touch pen shown in fig. 3 to 6, since the reflection device provided on the pen point 12 is different, the reflection angle is different when the infrared signal is reflected.
The method for determining the type of the target object is applied to the technical field of touch control. Currently, when information is input in a touch panel through a target object, the position of the target object can be determined through an infrared touch technology, so that an operation track is determined for writing. However, the current solution can only determine the touch position of the target object in the touch panel, and cannot identify the target object differentially.
In order to realize the differential recognition of the target object, image information including the target object can be acquired in an attempt, and the image information is analyzed, so that the target object is recognized. However, in the above method, since image information needs to be acquired, hardware cost is high, and the acquired image information needs to be analyzed, which results in high complexity of target object recognition.
Based on the above discussion, in order to reduce the hardware cost and the complexity of target object identification, embodiments of the present application provide a method for determining a target object type, where when a touch operation of a target object on a touch panel is detected, a receiving state of an infrared receiver for an infrared signal emitted by an infrared emitter is determined, and then a target type of the target object is determined according to the receiving state. The target type of the target object can be determined by judging the receiving state of the infrared signal, so that the target object can be identified in a differentiation manner, and the hardware cost and the complexity of target object identification can be reduced.
Hereinafter, the technical solution of the method for determining a target object type provided by the present application will be described in detail through a detailed embodiment. It is to be understood that the following detailed description may be combined with other embodiments, and that the same or similar concepts or processes may not be repeated in some embodiments.
Fig. 7 is a flowchart illustrating a method for determining a type of a target object according to an embodiment of the present disclosure, where the method may be applied to the touch panel shown in fig. 1, and a side frame of the touch panel is provided with an infrared emitter and an infrared receiver. For example, referring to fig. 7, the method for determining the type of the target object may include:
step 701: and when the touch operation of the target object on the touch panel is detected, determining the receiving state of the infrared receiver on the infrared signal sent by the infrared transmitter.
In this step, the target object may include a stylus or may include a finger, and of course, may also include a stylus and a finger.
When the target object is in contact with the touch panel, the touch panel can detect that the target object performs a touch operation on the touch panel. At this time, the receiving state of the infrared receiver for the infrared signal from the infrared transmitter is determined. In another possible implementation manner, the receiving state may further include whether the infrared signal received by the infrared receiver is a reflected signal reflected by the target object.
Taking fig. 1 as an example, when a touch operation of a target object on the touch panel is detected, a receiving state of infrared signals sent by a plurality of first infrared receivers 3 arranged on the second side frame RX-X to a plurality of first infrared transmitters 1 arranged on the first side frame TX-Y is determined, that is, whether the infrared signal sent by each first infrared transmitter 1 is received by a corresponding first infrared receiver 3 is determined, or whether the infrared signal received by each first infrared receiver 3 is a reflected signal after being reflected by the target object is determined.
Similarly, the receiving status of the infrared signals from the plurality of second infrared transmitters 2 disposed on the fourth side frame TX-X by the plurality of second infrared receivers 4 disposed on the third side frame RX-Y is also determined. That is, it is determined whether the infrared signal sent by each second infrared transmitter 2 is received by the corresponding second infrared receiver 4, or whether the infrared signal received by each second infrared receiver 4 is a reflected signal after being reflected by the target object.
Step 702: and determining the target type of the target object according to the receiving state.
In this step, after determining the receiving state of the infrared receiver for the infrared signal sent by the infrared transmitter, the target type of the target object may be determined according to the receiving state. Wherein different types represent different target objects.
In one possible implementation, the target type is determined to be a first type if no infrared signal in at least one optical network path is received.
Specifically, fig. 8 is a schematic diagram of an operation of a target object on a touch panel, and fig. 9 is another schematic diagram of an operation of a target object on a touch panel, as shown in fig. 8 and fig. 9, according to the foregoing description, an optical network path is formed between the corresponding first infrared emitter 1 and first infrared receiver 3, and an optical network path is formed between the corresponding second infrared emitter 2 and second infrared receiver 4. If a user performs a touch operation on the touch panel through a target object, if at least one first infrared receiver 3 does not receive an infrared signal sent by a corresponding first infrared transmitter 1, that is, at least one first infrared receiver 3 does not receive an infrared signal in a corresponding optical network path, or at least one second infrared receiver 4 does not receive an infrared signal sent by a corresponding second infrared transmitter 2, that is, at least one second infrared receiver 4 does not receive an infrared signal in a corresponding optical network path, or at least one first infrared receiver 3 does not receive an infrared signal sent by a corresponding first infrared transmitter 1, and at least one second infrared receiver 4 does not receive an infrared signal sent by a corresponding second infrared transmitter 2, it is determined that the target object triggering the touch operation blocks the infrared signals, for example, the infrared signals are blocked by the stylus 5 or the finger 7, and a transmission path of the infrared signals is terminated, at this time, it may be determined that the target type of the target object is the first type, where the first type is a type that cannot reflect the infrared signals, for example, the first type of target object may include the stylus 5 or the finger 7, etc., a pen point of which does not have a reflection function, and of course, the first type of target object may also include other objects, such as a pointer, etc., and for the first type of target object, the embodiment of the present application is not limited herein.
The stylus 5 may be the stylus shown in fig. 2, and the specific structure may refer to the description of fig. 2, which is not described herein again.
In this implementation, if it is determined that the infrared signal in the at least one optical network path is not received, the target type is determined to be the first type, so that the manner of determining the type of the target object can be simplified.
In another possible implementation manner, it is determined whether each of the received at least one infrared signal is a reflected signal reflected by the target object, and if there is a reflected signal reflected by the target object in which the first infrared signal is present, it is determined that the target type is the second type.
Specifically, it may be determined whether each of the received at least one infrared signal is reflected by the target object, and if it is determined that the first infrared signal is a reflected signal reflected by the target object, for example, the infrared signal is reflected by a pen point of the stylus pen, it may be determined that the target type of the target object is a second type, where the second type is a type capable of reflecting the infrared signal.
With continued reference to fig. 8 and 9, if the infrared signal received by at least one second infrared receiver 4 is a reflected signal, it indicates that the target object triggering the touch operation reflects the infrared signal sent by the first infrared transmitter 1 or the second infrared transmitter 2, for example, the infrared signal is reflected by the stylus 6, and at this time, it may be determined that the target type of the target object is the second type, that is, the type capable of reflecting the infrared signal.
The stylus 6 may be a stylus shown in fig. 3 to 6, and the specific structure may refer to the description of fig. 3 to 6, which is not described herein again.
In this implementation, by determining whether each received infrared signal is a reflected signal reflected by the target object, if there is a reflected signal reflected by the target object in which the first infrared signal is, the target type of the target object may be determined to be the second type, so that the complexity of determining the type of the target object may be reduced.
For example, when determining whether each of the received at least one infrared signal is a signal reflected by the target object, the following steps may be performed: and judging whether each infrared signal is received from a preset optical network path or not, and if the first infrared signal is received from a non-preset optical network path, determining that the first infrared signal is a signal reflected by the target object.
Specifically, fig. 10 is a further schematic view illustrating an operation of a target object on the touch panel, and as shown in fig. 10, an infrared signal emitted by each second infrared emitter 2 is transmitted through a preset optical network path and received by a correspondingly arranged second infrared receiver 4. Similarly, the infrared signal sent by each first infrared transmitter 1 is transmitted through a preset optical network path and received by a correspondingly arranged first infrared receiver 3. If some first infrared signals received by the first infrared receiver 3 are not received from the predetermined optical network path, it indicates that the first infrared signals may be reflected by the stylus 6 after being sent from the second infrared transmitter 2, and the first infrared signals are reflected to the first infrared receiver 3, and at this time, it may be determined that the first infrared signals are reflected signals reflected by the stylus 6.
In this embodiment, by determining whether each infrared signal is received from a preset optical network path, if it is determined that the first infrared signal is received from a non-preset optical network path, it is determined that the first infrared signal is a reflected signal reflected by the target object, so that the determination method of the reflected signal is simpler.
Further, in order to improve the accuracy of target object identification, when the target type of the target object is identified to be the second type, the target object can be further identified more accurately according to the receiving angle of the reflected signal.
For example, the subclass of the second type corresponding to the target receiving angle may be determined by obtaining the target receiving angle of the reflected signal and according to a corresponding relationship between a preset receiving angle and the type of the target object.
Specifically, as shown in fig. 3 to fig. 6, when the structures of the reflection devices disposed on the pen points of the touch pens are different, the reflection angles of the reflected signals by the touch pens are different, and accordingly, the receiving angles of the reflected signals received by the first infrared receiver or the second infrared receiver are different. Therefore, it is possible to previously determine a reception angle at which the reflected signal reflected by each stylus pen is received, thereby establishing a correspondence between the reception angle of the reflected signal and the type of stylus pen, and store the correspondence. For example: and if the receiving angle of the reflected signal is 30 degrees, the stylus pen provided with the four-sided mirror reflection device is corresponding to the pen point, if the receiving angle of the reflected signal is 45 degrees, the stylus pen provided with the six-sided mirror reflection device is corresponding to the pen point, if the receiving angle of the reflected signal is 65 degrees, the stylus pen provided with the full-circle mirror reflection device is corresponding to the pen point, and the like. The above correspondence relationship is only an example, and in an actual implementation process, the correspondence relationship between the receiving angle of the reflection signal and the type of the stylus pen is not limited thereto.
If it is determined that the first infrared signal is a reflected signal reflected by the target object, a target receiving angle of the reflected signal may be obtained, and a subclass of a second type corresponding to the target receiving angle may be determined according to a correspondence relationship between a pre-stored receiving angle and a type of the target object, where the subclass may be understood as a further subdivision of the stylus pen capable of reflecting the infrared signal.
In this embodiment, the target receiving angle of the reflected signal is obtained, and the subclass of the second type corresponding to the target receiving angle is determined according to the corresponding relationship between the preset receiving angle and the type of the target object, so that the accuracy of target object identification can be improved.
It should be noted that the method for identifying the target type of the target object may be performed only when the target object is detected to start a touch operation in the touch panel, and after the identification is completed, as long as the target object does not leave the identification range of the touch panel within a set time, the identification process is not performed any more, so that the computation amount of the infrared signal is not increased, and the complexity of the identification of the target object can be reduced.
In addition, it should be noted that when a plurality of target objects are simultaneously operated in the touch panel, the target type of each target object can be determined separately in the above manner.
Further, after the target type of the target object is determined, the track attribute corresponding to the target type can be determined according to the preset corresponding relationship between the type of the target object and the track attribute, and the touch track corresponding to the touch operation is controlled to be displayed according to the track attribute.
Specifically, the track attribute may include at least one of a color, a thickness, or a font, and of course, the track attribute may further include other information, such as a shape, and the like, and the embodiment of the present application is not limited herein for a specific form of the track attribute.
The corresponding relationship between the type and the track attribute is preset in the touch panel, for example: the track attribute corresponding to the touch track of the target object without the reflection function is red, the track attribute corresponding to the touch track of the target object with the pen point provided with the four-side mirror reflection device is green, and the track attribute corresponding to the touch track of the target object with the pen point provided with the six-side mirror reflection device is yellow and the like.
After the target type of the target object is determined, the track attribute corresponding to the target type can be determined according to the corresponding relation, so that the touch tracks corresponding to the subsequent touch operation of the target object are controlled to be displayed according to the determined track attribute.
In this embodiment, according to the preset correspondence between the type of the target object and the track attribute, the track attribute corresponding to the target type is determined, and the touch track corresponding to the touch operation is controlled to be displayed according to the track attribute, so that not only can the displayed content be diversified, but also different requirements of the user can be met, and the user experience is improved.
According to the method for determining the type of the target object, when the touch operation of the target object on the touch panel is detected, the receiving state of the infrared receiver on the infrared signal sent by the infrared transmitter is determined, and then the target type of the target object is determined according to the receiving state. The target type of the target object can be determined by judging the receiving state of the infrared signal, so that the target object can be identified in a differentiation manner, and the cost and the complexity of target object identification can be reduced.
