Detailed Description

Touch screens are widely applied in daily life, and can be applied to devices such as smart phones, tablet computers and electronic whiteboards. For example, in a conference, an electronic whiteboard including a large-sized touch screen may not only dynamically present information to participants, but also provide an interactive function. Touch screens mainly include capacitive type, resistive type, infrared type and the like, and capacitive touch screens are widely applied due to the superior performance of the capacitive touch screens.

The use of touch screens also has led to a wide variety of touch pens used in touch screens, which can be used for clicking, drawing, marking or pointing operations. The pen point of the touch pen is generally made of a conductive material, and when the pen point contacts the touch screen, the touch screen detects an induction signal, so that a touch point formed by the conductive body on the touch screen is identified, and interactive operation is realized according to the position and the position change of the touch point. With the development of the technology, the touch screen can recognize not only the contact touch but also the floating touch. The floating touch refers to that, within a certain range from the surface of the touch screen, when the pen point of the touch pen is close to the surface of the touch screen but not in contact with the touch screen, the touch screen can sense a touch point and realize interaction. The suspension touch control provides richer and diversified operation experience for users. The touch mentioned in the present application may refer to a touch or a hover touch.

Currently, the touch pens in wider application include passive touch pens and active touch pens. The passive stylus has single function and simple structure. If a user using the passive stylus wishes to implement differentiation operations such as switching brush colors, replacing brush types (for example, replacing a writing brush and a sign pen), or switching brush thicknesses, the user needs to click the function control on a software interface (for example, software such as a drawing and a whiteboard) displayed on the touch screen. This results in additional operation steps for the user using the passive stylus to perform the differential operation. The active touch pen can actively send control signals of differential operation to the touch screen, so that differential operation steps are simplified. However, since the active stylus needs to generate and actively transmit a control signal for differentiated operations to the touch screen, additional devices such as a chip, a circuit, or a sensor are required. Therefore, the active stylus is more complex in structure and higher in cost.

To the above problem, the application provides a touch control pen, through arrange in proper order along the length direction of touch control pen on the touch control pen and set up a plurality of electric conductors to the electric conductivity constant of a plurality of electric conductors is different or wherein at least one electric conductor electric conductivity constant distributes unevenly, according to the position relation between a plurality of electric conductors and the touch screen, discerns the gesture of touch control pen, according to the position relation of difference, carries out different operations, thereby realizes the multi-functional operation of differentiation conveniently.

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments.

According to the touch control method and the touch control device, the plurality of conductive bodies are arranged on the touch control pen, when the gesture of the user holding the touch control pen changes, the position relation between the plurality of conductive bodies and the touch control screen changes, and therefore the touch control parameters of the touch control pen can be switched according to the change of the position relation. As shown in fig. 1, the plurality of conductors 101 to 103 may be arranged in sequence along the longitudinal direction of the stylus pen 1. When the conductors 101-103 contact or approach the touch screen, the capacitance of the touch screen is affected, and the touch screen detects the capacitance. Some conductors (such as conductors on the pen point or conductors at the pen tail) in the multiple conductors on the touch pen can be directly used for interacting with the touch screen to realize touch operation, other conductors can be used for realizing touch operation, and the conductors can be only used for realizing a certain function in cooperation with other conductors (such as conductors in the middle of the touch pen can be used for realizing detection of position relation between the multiple conductors of the touch pen and the touch screen in cooperation with the conductors on the pen point).

How to realize the differentiated multifunction by the stylus provided by the present application will be described in detail below.

For convenience of description, the positional relationship between the plurality of conductive bodies and the touch screen before being changed is referred to as a first positional relationship, and the positional relationship after being changed is referred to as a second positional relationship.

When the touch screen can only identify touch operation, the change of the position relationship between the plurality of conductors and the touch screen can be judged according to the change of the number of the identified conductors. For example, as shown in fig. 2, the stylus 1 includes a first conductor 101 at the tip of the pen and a second conductor 103 at the tail of the pen. The positional relationship between the plurality of conductors of the stylus and the touch screen shown in fig. 2 is a positional relationship during normal writing of the stylus, and the positional relationship may be set to a first positional relationship. When in the first positional relationship, the stylus 1 and the touch screen 2 form a certain included angle α, and in this posture, the touch screen recognizes only the first conductor 101. As shown in fig. 3, in the posture of the stylus, the first conductor 101 and the second conductor 103 both contact the touch screen (the distances from the first conductor 101 and the second conductor 103 to the touch screen are both 0). The positional relationship between the conductive body and the touch panel may be set to a second positional relationship. When in the second positional relationship as shown in fig. 3, the touch screen can recognize the two conductive bodies. The gesture is obviously not a writing state commonly used by a user, so the position relation between the conductors and the touch screen is obtained by judging the number of the conductors identified by the touch screen, and the position relation change between the conductors and the touch screen is detected by the change of the number of the identified conductors. For the above scenario, when it is detected that the number of the conductive bodies is changed from one to 2, it can be determined that the positional relationship between the plurality of conductive bodies on the stylus pen and the touch screen is changed, that is, the positional relationship is changed from the first positional relationship to the second positional relationship.

When the touch screen can recognize the floating touch operation, the recognized conductive body may include a conductive body contacting with the touch screen and a floating conductive body not contacting with the touch screen. Therefore, it is difficult to accurately determine a change in the positional relationship between the conductive body on the stylus pen and the touch panel only by a change in the detected number of conductive bodies. As will be understood by those skilled in the art, the smaller the distance between the conductive body and the touch screen, the greater the intensity of the generated touch signal. Therefore, the distance between the conductive bodies and the touch screen can be determined by combining the signal intensity detected by the touch screen, so that the position relation between the plurality of conductive bodies and the touch screen can be obtained. For example, in the first positional relationship, the first conductive body is close to or in contact with the touch screen. At this time, the distance from the second conductor to the touch screen is far greater than the distance from the first conductor to the touch screen, and the touch screen can only detect the first conductor or detect that the signal intensity of the first conductor is far greater than that of the second conductor. When the first conductor and the second conductor are detected and the signal intensities of the two conductors are almost equal, it can be determined that the distance from the first conductor to the touch screen is equal to the distance from the second conductor to the touch screen, that is, the positional relationship between the conductors and the touch screen is changed into the second positional relationship. It should be noted that when the number of the conductors arranged along the length direction of the stylus pen is more than 2, the distances from the plurality of conductors to the touch screen are all unequal to equal, that is, the distances from the first position relationship to the second position relationship are changed.

In order to more accurately judge the position relationship between the plurality of conductive bodies on the touch pen and the touch screen, the distance between touch points generated by the conductive bodies on the touch screen can be calculated, and when the distance between the touch points is within a preset range, the conductive bodies and the touch screen are judged to be in the first position relationship. As shown in fig. 2 and fig. 3, a distance d between a first touch point generated on the touch screen 2 by the first conductive body 101 and a second touch point generated on the touch screen 2 by the second conductive body 103 is detected by the touch screen 2₁The distance between the first conductor 101 and the second conductor 103 on the stylus 1 is denoted by d₂. When the stylus is in the normal writing position, d, as shown in FIG. 2₁Is less than d₂. In the second positional relationship as shown in FIG. 3, d₁And d₂Are almost equal. Thus, d can be₂The range in the vicinity may be (d) as a preset range₂-a，d₂+ a), where a is a relatively small value. When d is detected₁At (d)₂-a，d₂Within + a), d can be considered to be₁And d₂Almost equal, it can be judged that the second positional relationship is present. It should be noted that the size of the preset range may be determined according to the second positional relationship, and when the second positional relationship is not the positional relationship shown in fig. 3, for example, when there is a small included angle between the stylus and the touch screen, the preset range needs to be calculated according to the distance between the conductor and the stylus and the included angle. In addition, the size of the preset range can be flexibly adjusted according to the precision of the touch screen and the like (that is, the value of a in the above embodiment can be flexibly adjusted). The method for acquiring the preset range is not limited, and for example, the preset range may be calibrated according to the second position relationship before the stylus is normally used, or may be directly input by the user.

Since the difference between the second positional relationship and the first positional relationship is large, for most touch screens, it is easier to recognize the second positional relationship. For the user, the first positional relationship of the stylus is converted into the second positional relationship, and usually only the wrist is slightly rotated, so that the operation is convenient for the user.

It will be understood by those skilled in the art that the second positional relationship is not limited to the positional relationship shown in fig. 4, but may be other positional relationships different from the first positional relationship. For example, the position relationship between the conductive body and the touch screen when the angle between the touch pen and the touch screen is small can be used. Because the position relationship between the conductive body and the touch screen corresponds to the gesture of the user using the touch pen, the second position relationship can be defined by the user according to the common writing gesture of the user, or the user inputs the second position relationship according to the preference of the user.

It can be understood that the more the number of the conductive bodies arranged on the touch pen is, the more accurate the judgment of the position relationship between the conductive bodies and the touch screen is. The number, arrangement interval, size, shape and the like of the plurality of electric conductors are not limited. For example, a plurality of electric conductors may be arranged at fixed intervals. For example, the conductor arrangement positions may be: the stylus tip (shown in fig. 1 as the first conductor 101), the center of the stylus body (shown in fig. 1 as the third conductor 102), or the stylus tip (shown in fig. 1 as the second conductor 103), etc. For another example, the conductor may be in the form of a block, a ring, or a sphere. The conductive body may also be removably mounted to the stylus. The specific setting mode can be flexibly selected according to the processing difficulty, the user requirements and the like.

The application provides a touch-control pen can be passive touch-control pen, only needs to set up comparatively simple structure can realize the discernment of the position relation of electric conductor and touch-control screen, for example only need increase an electric conductor at least, constitute a plurality of electric conductors jointly with the electric conductor of nib, can realize detecting the change of electric conductor and touch-control screen position relation. This greatly simplifies the hardware structure and saves cost. Of course, the present application can also be applied to an active stylus, which can simplify the structure of the active stylus and enable the active stylus to have a function of detecting a change in the positional relationship between the conductor and the touch screen or recognizing the gesture of the stylus.

After the position relation between the conductor and the touch screen is changed and identified, the gesture of the touch pen can be identified, and diversified functions, such as a function of replacing touch parameters, can be realized according to different gestures of the touch pen. The operation of replacing the touch parameter can be applied to scenes such as whiteboards, drawings or records. Touch parameters may include, but are not limited to: the color of the touch control pen brush, the type of the pen brush, the transparency of the pen brush, the color saturation of the pen brush, the color brightness of the pen brush or the thickness of the pen brush, etc.

As an embodiment, when the change of the position relationship is that the distances from the plurality of conductive bodies to the touch screen are changed from unequal to equal, the first touch parameter of the stylus is switched. The first touch parameter includes, but is not limited to, any one of the following: the brush color, brush type, or brush thickness of the stylus. The second positional relationship may be the positional relationship shown in fig. 4 or other postures. Taking the switching of the brush color and the second positional relationship as the positional relationship shown in fig. 4 as an example, when it is detected that the positional relationship between the plurality of conductors on the touch pen and the touch screen is switched from the first positional relationship to the second positional relationship, the color of the brush is switched according to the preset brush color sequence. For example, the preset brush colors may include red and black, if the black brush used by the user is normally recorded, when the user adjusts the stylus to a horizontally placed state, and the touch screen recognizes the operation, the brush color is switched to red, and then the user may perform key marking using the red brush; if the user adjusts the stylus to be in the horizontal placement state again, after the touch screen recognizes the operation, the color of the brush can be changed back to black, and the user continues to record by using the black brush. Or, the preset brush colors of the execution component are multiple, and the sequence is as follows: the color of the brush changes once when the user adjusts the stylus to be horizontally placed once, and the color changes cyclically according to the preset sequence of red, yellow, blue, green and black. The specific preset colors and the preset color sequence are not limited in the application, and the user can also select the colors in an independent customization mode.

According to the embodiment, the touch control pen is simple in structure, the touch control parameter switching operation is achieved by identifying the position relation change between the plurality of electric conductors and the touch control screen on the touch control pen, and the functions of the touch control pen are enriched.

As an example, the plurality of conductors on the stylus have different conduction constants and/or any one of the plurality of conductors has a non-uniform distribution of conduction constants. The touch control parameters can be further adjusted according to the sensing signals.

For example, the plurality of conductors on the stylus may have different conductivity constants in one direction, e.g., along the length or circumference of the stylus body.

For example, the first conductor at the pen head and the second conductor at the pen tail have different conduction constants, and when both conductors are in the detection range, the touch screen can detect that the two conductors are arranged, and can distinguish which conductor is the first conductor and which conductor is the second conductor according to different induction signals generated by different conduction constants. In view of this, the "switching the first touch parameter of the stylus pen when the distances from the plurality of conductive bodies to the touch screen are changed from unequal to equal when the positional relationship is changed as described in the foregoing embodiment", when the first conductive body and the second conductive body are specifically equal to the touch screen, the switching of the different touch parameters may further be performed according to the difference in the relative positions of the first conductive body and the second conductive body, as specifically shown in fig. 4, which may include at least one of the following situations:

as shown in fig. 4(a), when the position relationship changes such that the distances from the first conductor 101 and the second conductor 103 to the touch screen 2 are changed from unequal to equal, and the first conductor 101 is on the left side of the second conductor 103, the color of the brush is switched according to a first preset sequence;

as shown in fig. 4(b), when the position relationship changes such that the distances from the first conductor 101 and the second conductor 103 to the touch screen 2 are changed from unequal to equal, and the first conductor 101 is on the right side of the second conductor 103, the color of the brush is switched according to a second preset sequence opposite to the first preset sequence;

as shown in fig. 4(c), when the change of the positional relationship is that the distances from the first conductor 101 and the second conductor 103 to the touch screen 2 are changed from unequal to equal (i.e., the stylus is parallel to the touch screen surface), and the first conductor 101 is on the lower side of the second conductor 103, the brush type in the first touch parameter is switched;

as shown in fig. 4(d), when the change of the positional relationship is that the distances from the first conductor 101 and the second conductor 103 to the touch panel 2 are changed from unequal to equal (i.e., the stylus is parallel to the touch panel surface), and the first conductor 101 is on the upper side of the second conductor 103, the brush thickness in the first touch parameter is switched. Or the conductive constants of one of the plurality of conductive bodies are distributed unevenly, so that the conductive constants of different positions on the conductive body are different, and when the different positions on the conductive body are in contact with or close to the touch screen, the sensing signals sensed by the touch screen are different, so that the touch parameters can be further adjusted according to the change of the sensing signals.

For example, the first conductive body at the tip of the stylus pen has a non-uniform distribution of conduction constants, and the second touch parameter is switched when the position on the first conductive body that is in contact with or close to the touch screen is changed.

When the first conductive body rotates clockwise or counterclockwise, the sensing signals detected by the touch screen are different, and the capacitance detected in the process of rotation is changed. Therefore, the current angle corresponding to the first conductor can be determined according to the capacitance change, and the rotation angle of the first conductor can be obtained according to the historical angle of the first conductor.

In one embodiment, the second touch parameter can be determined and switched directly according to the difference of the sensing signals detected by the touch screen; in another embodiment, the second touch parameter may also be determined and switched according to the obtained rotation angle of the first conductive body. The second touch parameter may be, for example, the thickness of the brush, the saturation of the brush color, or the transparency of the brush. The second touch parameter may be the same as the first touch parameter or different from the first touch parameter. For example, the first touch parameter is a brush color, the second touch parameter is a transparency of the touch brush, and different sensing signals detected by the touch screen or different rotation angles of the first conductor correspond to different transparencies. When the position relation between the conductive body and the touch screen is changed from the first position relation to the second position relation, the color of the brush is switched. And then, when the first position relation is recovered, the user uses the touch pen to normally perform touch operation. When a user rotates the first conductor of the pen point on the touch screen, the touch screen identifies the rotation angle of the first conductor, and the transparency of the brush under the current brush color can be switched according to the transparency or the transparency variation corresponding to the rotation angle.

The control method provided by the application can control the touch pen to realize the touch mode, and can also realize other more modes, such as an eraser mode, and an erasing function.

As an example, when the positional relationship between the conductive body and the touch panel is changed to the third positional relationship, the function of the stylus pen is converted from the writing function to the erasing function of the eraser. The third positional relationship may be, for example, a positional relationship when the pen tail of the touch pen contacts or approaches the touch screen and the pen head is far away from the touch screen. The gesture of the user using the touch pen corresponding to the position relation is more consistent with the gesture of the user using the common pencil with the eraser for erasing, and the gesture is more consistent with the daily use habit of the user. Therefore, the operation is more convenient and flexible for users.

The method for detecting the third positional relationship may be, for example: when the second conductor at the tail of the stylus is detected to be close to or contact with the touch screen and the first conductor at the head of the stylus is detected to be far away from the touch screen, namely the stylus is in an inverted posture, the third position relation between the conductor of the stylus and the touch screen is judged, and the function of the stylus is converted from a writing mode to an erasing mode.

The second conductor can be arranged differently from the first conductor or other conductors on the pen point, so that the touch screen can distinguish and distinguish the second conductor, and misjudgment is avoided. Alternatively, the volume of the conductor, the contact area with the touch screen, or the conductivity constant, etc. may be different.

As an example, the second conductor at the pen tail has a non-uniform distribution of conduction constants. When the touch pen is in the eraser function, when the position of the second conductor, which is in contact with or close to the touch screen, is changed, the capacitance variation caused on the touch screen is also changed, and different capacitance variations can correspond to different eraser parameters. Parameters of the eraser may include, for example: degree of erasure, shape of eraser, size of eraser, etc. Taking the parameter of changing the erasing degree of the eraser as an example, when the conductive constant of the position on the second conductor, which is in contact with or close to the touch screen, is smaller, the capacitance change of the touch screen is smaller, the image of the corresponding position cannot be completely erased by using the eraser, but the visibility of the image of the corresponding position is reduced to a certain extent; when the conductive constant of the position on the second conductor, which is in contact with or close to the touch screen, is larger, the visibility of the corresponding image is reduced to the lowest, namely the image is erased. In this case, it will be appreciated that the eraser may be a brush that has the same background color as the current canvas and a transparency that may vary according to the conductivity constant.

Alternatively, the stylus may be an active stylus or a passive stylus.

The above description is only exemplary of the present application and should not be taken as limiting the present application, as any modifications, equivalents and the like that are within the spirit and principle of the present application should be included in the scope of the present application.
