However, it will be apparent to those skilled in the art that, in the various embodiments of the present invention, numerous technical details are set forth in order to provide the reader with a better understanding of the present application. However, the technical solutions claimed in the present application can be implemented without these technical details and various changes and modifications based on the following embodiments.

The first embodiment of the present invention relates to an active pen, which is mainly applied to an electronic device with touch and display operations such as a smart phone or a tablet computer. Please refer to FIGS. 1 and 2 for the active pen in the present embodiment.

The active pen 100 includes a capacitive touch sensor 101, a processing unit 102, a wireless transceiver 103, and a pen case 104.

The capacitive touch sensor 101 is disposed on the pen case 104 for detecting touch information. Preferably, the capacitive touch sensor 101 is generally disposed at a user's pen position. Wherein, in general, the capacitive touch sensor 101 is mounted on the outer surface of the pen case; however, it is not limited thereto, when the pen case 104 is made of an insulating material and the thickness of the pen case 104 is made very thin, the capacitive touch sensor The 101 may also be mounted on the inner surface of the pen case as long as the capacitive touch sensor 101 located on the inner surface of the pen case 104 senses a gesture operation acting on the outer surface of the pen case 104.

The capacitive touch sensor can adopt a self-capacitive touch sensor. The structure of the self-capacitive touch sensor is relatively simple, and the pen case 104 can be relatively thin and light, and the user can be more comfortable when operating the active pen. Of course, in practical applications, the touch sensor is not limited to being self-contained, and a mutual touch sensor can also be used. In addition, the active pen also contains other electronic components, such as buttons, pressure Force sensor, accelerometer, etc.

The processing unit 102 is coupled to the capacitive touch sensor 101 and the wireless transceiver 103 for generating a gesture signal according to the touch information detected by the capacitive touch sensor 101.

The wireless transceiver 103 is configured to transmit the gesture signal generated by the processing unit 102 to the master device. Specifically, the wireless transceiver can be a Bluetooth transceiver or a wireless network transceiver, and establish a communication connection between the active pen and the master device by using a Bluetooth transceiver or a wireless network transceiver, thereby realizing interaction between the active pen and the master device. Of course, the wireless transceiver can also provide a communication connection established by the active pen through a custom communication protocol with the master device.

In practical applications, the interaction mode between the active pen and the master device is as shown in FIG. 2 .

The self-capacitive touch sensor 101 on the active pen 100 detects the touch of the human finger on the active pen 100, and the touch position and position movement information of the finger are analyzed by the self-capacitive touch sensor 101, and the information is analyzed by the processing unit. Finger touch and gesture operations, and then recognize the operational commands represented by these gesture operations throughout the system, enabling interaction with the touch screen (or trackpad) 200 of the master device.

In this embodiment, the capacitive touch sensor disposed on the pen case of the active pen recognizes the touch, slide, rotate, and press gestures of the finger, and transmits it to the processing unit for processing, and finally realizes and waits through the wireless transceiver. The interaction of the operating device enables the active pen itself to detect the touch and gesture of the finger, greatly enriching the functions and application scenarios of the active pen, and facilitating the user's operation. Moreover, with the self-contained touch sensor, the active pen is more compact and more convenient to operate.

It should be noted that, in practical applications, the inside of the pen body of the active pen can also be provided with a battery compartment, and the top of the pen body of the active pen can be unscrewed during use to place the battery; in addition, the pen of the active pen is also provided. There is a switch button for controlling the opening and closing of the active pen. The pen of the active pen can also be provided with a work indicator. When the switch is turned on, the indicator light is on when the active pen is in the working state; when the user turns off the switch, the indicator light Off; in addition, the top of the active pen is also provided with a metal clip, which can be square The user puts the active pen in a pocket or a notepad to facilitate carrying; the present embodiment does not impose any restrictions on the specific structure of the active pen.

A second embodiment of the invention relates to an active pen, as shown in FIG. The embodiment is further improved on the basis of the first embodiment. The specific improvement is that the processing unit 102 includes a touch chip 1021 and a microcontroller 1022. The touch chip 1021 is connected to the capacitive touch sensor 101, and the micro control is performed. The device 1022 is connected between the wireless transceiver 103 and the touch chip 1021.

The touch controller 1021 is configured to generate a gesture signal according to the touch information. The microcontroller 1022 is configured to determine whether the gesture signal has a corresponding operation command according to the preset correspondence between the gesture signal and the operation command. When it is determined that the gesture signal does not have a corresponding operation command, the wireless transceiver 103 transmits the gesture signal; when it is determined that the gesture signal has a corresponding operation command, the microcontroller 1022 is further configured to determine whether the operation command matches the active pen 100. When it is determined that the operation command matches the active pen 100, the microcontroller 1022 controls the active pen 100 according to the operation command, and when it is determined that the operation command does not match the active pen 100, the microcontroller 1022 transmits the operation command through the wireless transceiver 103. To the main device.

After the corresponding relationship between the new gesture signal and the operation command is preset in the main device, the active pen may not be sent to the active pen storage in time; that is, if the gesture operation has not been used on the active pen, the active pen may There is no operation command corresponding to the gesture operation, and the gesture signal needs to be sent to the master device through the wireless transceiver at this time. Alternatively, it may be set that only the gesture operation matching the active pen and its corresponding operation command are stored on the active pen, and therefore, when the master device is to be controlled by applying a gesture operation on the active pen, the active pen is The operation command corresponding to the gesture operation is not obtained, so the gesture signal is sent to the master device.

In addition, the microcontroller 1022 is further configured to receive and store an operation command corresponding to the gesture signal returned by the master device and the gesture signal. The active pen 100 stores the used gesture signal and the corresponding operation command, so that when the same gesture is detected next time, the corresponding operation command can be directly obtained to operate the device, which is convenient for operation.

In this embodiment, the self-capacitive touch sensor may be a triangular pattern self-contained touch sensor or a dot pattern self-contained touch sensor.

As shown in FIG. 4, the sensor of the active pen is a triangular pattern self-contained touch sensor; when the user touches the triangular pattern self-contained touch sensor, a touch information is generated, and the triangular pattern is self-contained by the small triangle touched by the touch sensor (here The triangular pattern self-capacitive touch sensor of the small triangular area in FIG. 4 detects the generated touch information and acquires specific touch position and position movement information. As shown in FIG. 5, the sensor of the active pen is a dot matrix self-contained touch sensor; when the user touches the dot pattern self-capacitive touch sensor, the touch information is also generated, and the dot pattern is self-touched by the touch sensor. The pattern (here, the dot pattern self-capacitive touch sensor of the dot area in FIG. 5) detects the generated touch information and acquires specific touch position and position movement information.

The following describes the specific working principle of the triangular pattern self-capacitive touch sensor and the dot pattern self-capacitive touch sensor.

6 is a development of a triangular pattern self-contained touch sensor along a circular cross section of an active pen, wherein the x direction in the coordinate axis is the axial direction of the pen and the y direction is the circumferential direction of the pen case. When the finger is placed at a certain position, the triangular pattern of the position detects the change of the capacitance by the self-capacitive touch sensor, and the position of the finger in the entire pattern can roughly determine the touch position of the finger. In a pair of triangular pattern self-capacitance sensors, when the finger is placed at a certain position, a more accurate position in the x direction can be determined by comparing the magnitudes of the changes in the capacitance of the A and B, and also in the y direction. More precise location. The structure can detect the touch position of a single finger or a plurality of fingers, or detect and recognize the palm of the hand to hold the active pen over a large area. The touch chip can recognize operations such as sliding, rotating, holding, etc. by continuously detecting the touch position in time.

7 is a development of a dot pattern self-contained touch sensor along a circular cross section of the active pen, wherein the x direction in the coordinate axis is the axial direction of the pen, and the y direction is the circumferential direction of the pen body. When the finger is placed in a position of the dot pattern self-contained touch sensor, the independent small self-touch sensor at its location The capacitance detected by the device changes, and the position of the finger touch can be detected by the position of the independent small self-contained touch sensor. When a finger touches, it usually covers multiple independent small self-contained touch sensors. The amount of capacitance change detected by each of these independent small self-contained touch sensors can be calculated more accurately by interpolation. Touch the location. The dot matrix structure can also detect the touch position of a single finger or multiple fingers, or detect and recognize the palm of the hand to hold the active pen over a large area. The touch chip can recognize operations such as sliding, rotating, holding, etc. by continuously detecting the touch position in time.

It should be noted that, in practical applications, the number of small triangles in the triangular pattern self-capacitive touch sensor and the number of small dots in the dot matrix self-capacitive touch sensor can be according to the self-touch that needs to be set on the active pen. The size of the sensor area is determined. If the coverage area of the self-capacitive touch sensor that needs to be set on the pen case is larger, each small triangle that constitutes a triangular pattern self-contained touch sensor or a self-contained touch sensor that constitutes a dot matrix pattern The fewer dots, and each small triangle or small dot needs to be connected to the touch chip. Of course, the self-contained touch sensor can also be other patterns, such as a rectangle, a diamond, and the like, and is not limited to a triangle and a circle.

In this embodiment, the self-capacitance touch sensor on the active pen detects the touch of the finger of the human finger on the active pen, and obtains the touch position and position movement information of the finger through the analysis of the touch chip on the active pen, and the information is touched by the touch chip. Analyze to get finger touch and gesture operations. The touch chip transmits this information to the active pen's microcontroller (MCU), which recognizes the operational commands that these gestures represent throughout the system. If the instruction is to perform an operation on the active pen itself, an operation is directly performed on some modules on the active pen. If an operation is performed on the primary device, the operation command is transmitted through the wireless transmission module on the pen. For the master device, the master device performs corresponding operations, thereby greatly enriching the functions and application scenarios of the active pen.

It is worth mentioning that each module involved in this embodiment is a logic module. In practical applications, a logical unit may be a physical unit, a part of a physical unit, or multiple physical entities. A combination of units is implemented. Moreover, in order to highlight the innovative part of the invention, The present embodiment does not introduce a unit that is not closely related to solving the technical problem proposed by the present invention, but this does not mean that there are no other units in the present embodiment.

A third embodiment of the present invention relates to an active pen-based gesture detection method, and a specific operation flow is shown in FIG. 8.

In step 801, touch information is detected by a capacitive touch sensor.

Specifically, the touch information detected by the active pen through the capacitive touch sensor disposed on the pen case mainly includes: touch position and position movement information.

More specifically, the detected touch information can be used to generate a gesture signal.

In step 802, a gesture signal is generated based on the touch information.

Specifically, the processing unit analyzes the touch information detected by the capacitive touch sensor to obtain a corresponding gesture signal.

In step 803, a gesture signal is sent to the master device via the wireless transceiver.

Specifically, the active pen sends the gesture signal analyzed by the processing unit to the master device through the wireless transceiver, so that the master device can obtain the corresponding operation instruction.

In this embodiment, the capacitive touch sensor disposed on the pen case of the active pen recognizes the touch, slide, rotate, and press gestures of the finger, and transmits it to the processing unit for processing, and finally realizes and the main through the wireless transceiver. The interaction of the device enables the active pen itself to detect the touch and gesture of the finger, which greatly enriches the function and application scenario of the active pen.

It is not difficult to find that the present embodiment is a system embodiment corresponding to the first embodiment, and the present embodiment can be implemented in cooperation with the first embodiment. The related technical details mentioned in the first embodiment are still effective in the present embodiment, and are not described herein again in order to reduce repetition. Accordingly, the related art details mentioned in the present embodiment can also be applied to the first embodiment.

A fourth embodiment of the present invention relates to an active pen based gesture detecting method. The embodiment is further improved on the basis of the third embodiment, and the specific improvement is that the active pen is in the hand Before the potential signal is sent to the master device, it is necessary to determine whether the gesture signal has a corresponding operation command. The specific operation flow is as shown in FIG. 9.

In step 901, touch information is detected by a capacitive touch sensor.

In step 902, a gesture signal is generated based on the touch information.

Since step 901 and step 902 in FIG. 9 are substantially the same as

steps

801 and 802 in FIG. 8, it is intended to detect touch information by a capacitive touch sensor disposed on the active pen, and the processing unit generates a gesture signal according to the touch information. I won't go into details here.

In step 903, it is determined whether the gesture signal has a corresponding operation command.

Specifically, after the gesture signal is generated, the active pen needs to determine whether the gesture signal has a corresponding operation command according to the preset correspondence between the gesture signal and the operation command. If there is a corresponding operation command, step 904 is performed; if not, step 904 is performed; Corresponding operation command, step 905 is performed.

In step 904, it is determined whether the operation command matches the active pen.

Specifically, the active pen determines whether there is a corresponding operation command by the generated gesture signal, and proceeds to the current step to determine whether the current corresponding operation command matches the active pen. If yes, the process proceeds to step 907; if not, if not Go to step 908.

In step 905, the gesture signal is sent to the master device via the wireless transceiver.

This step is substantially the same as step 803 in the third embodiment, and details are not described herein again.

In step 906, the gesture signal and the operation command returned by the master device are received and stored.

Specifically, the master device acquires a corresponding operation command according to the gesture signal sent by the active pen to implement the gesture operation function. Moreover, the master device sends an operation command corresponding to the gesture signal to the active pen to the active pen; the active pen receives the gesture signal and the operation command from the master device, and stores the corresponding relationship between the gesture signal and the operation command. When the gesture signal is detected next time, the operation command corresponding to the gesture signal can be found from the preset correspondence between the gesture signal and the operation command.

In general, the user can set a preset correspondence between the gesture signal and the operation command on the master device. When a gesture signal is used for the first time on the active pen (the gesture signal is not stored in the active pen), the active pen does not store the operation command corresponding to the gesture signal, and the active pen sends the gesture signal directly to the master device, and the master device The preset correspondence between the stored gesture signal and the operation command acquires the gesture signal to obtain a corresponding operation command and executes the operation command. Then, the active pen will receive the gesture signal and the operation command from the master device, and store the corresponding relationship between the gesture signal and the operation command. Therefore, when the active pen uses a gesture signal, the operation command corresponding to the gesture signal can be stored; so that the operation command corresponding to the gesture signal can be directly obtained when the gesture signal is used next time.

However, the embodiment does not impose any limitation on the specific manner in which the active pen stores the preset correspondence between the gesture signal and the operation command. For example, the user can directly set the preset correspondence on the active pen; or after the user sets the preset correspondence on the master device, the user can operate on the master device to synchronize the preset correspondence to the active pen. in.

In step 907, the active pen is controlled in accordance with the operation command.

Specifically, when the active pen passes the judgment, the determination operation command matches the active pen, and the active pen is directly controlled according to the operation command corresponding to the gesture signal. That is, the active pen can also perform self-control according to the gesture signal, thereby increasing the operational function of the active pen itself.

In step 908, an already existing operational command is sent to the primary device via the wireless transceiver.

Specifically, when the active pen determines that the operation command does not match the active pen, it indicates that the operation command corresponds to the master device, and the active pen sends the operation command to the master device.

According to the gesture detection method based on the active pen in the embodiment, on the basis of realizing the interaction between the active pen and the master device, the gesture signal is determined according to the preset relationship between the gesture signal and the operation command, and the corresponding operation is determined. Whether the command matches the active pen and determines whether the action command is for the active pen or the master device greatly enriches the function and application scenario of the active pen.

Since the second embodiment and the present embodiment correspond to each other, the present embodiment can be implemented in cooperation with the second embodiment. The related technical details mentioned in the second embodiment are still effective in the present embodiment, and the technical effects that can be achieved in the second embodiment can also be implemented in the present embodiment. To reduce the repetition, details are not described herein again. Accordingly, the related art details mentioned in the present embodiment can also be applied to the second embodiment.

The steps of the above various methods are divided for the sake of clear description. The implementation may be combined into one step or split into certain steps and decomposed into multiple steps. As long as the same logical relationship is included, it is within the protection scope of this patent. The addition of insignificant modifications to an algorithm or process, or the introduction of an insignificant design, without changing the core design of its algorithms and processes, is covered by this patent.
