BRIEF DESCRIPTION OF DRAWINGS

[0016] Figure 1 The flowchart of an information processing method in the embodiments of the present application is shown.

[0017] Figure 2 The hardware structure diagram of an electronic device in the embodiments of the present application is shown. DETAILED DESCRIPTION

[0018] In order to make the purposes, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be described in detail below with reference to the drawings of the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0019] The embodiments of the present application provide an information processing method, which is applied to an electronic device, and specifically can be applied to an electronic device as shown in Figure 1 The information processing method comprises the following steps:

[0020] S101. Sensing that the active stylus is located in the display area of the display screen, obtaining the device information of the active stylus.

[0021] In the embodiment of the present application, when the active stylus is at a distance of 0-3 cm from the display screen of the electronic device, the active stylus can sense the electric signal radiated by the display screen, so that the electronic device can receive the electric signal radiated by the display screen, analyze the electric signal according to a protocol supported by the active stylus, such as MPP or USI protocol, to obtain the first device information of the electronic device, then encode the device information of the active stylus and feed back to the electronic device through the electric signal of the active stylus, the electronic device can sense the electric signal fed back by the active stylus, and then the electronic device can obtain the device information of the active stylus by analyzing the electric signal based on the protocol supported by the active stylus. Then, the first communication connection with the active stylus is established according to the device information of the active stylus. In the process of establishing the first communication connection between the active stylus and the electronic device, the first communication mode is used for interaction, so the first communication mode is used to determine that the active stylus exists and is in an input state.

[0022] Therefore, in the process of establishing the first communication connection between the active stylus and the electronic device, the electronic device can receive the electric signal of the active stylus only when the active stylus is at a distance of 0-3 cm from the display screen, so it can be considered that the electronic device senses that the active stylus is located in the display area of the display screen when it receives the electric signal of the active stylus, and obtains the device information of the active stylus. The device information of the active stylus includes a device identifier, such as a device ID.

[0023] S102. Send a connection request based on the device information of the active stylus.

[0024] In the embodiment of the present application, after obtaining the device information of the active stylus, in order to establish a second communication connection with the active stylus, such as a Bluetooth connection, the first communication mode can be used to interact with the active stylus and send a connection request of the second communication mode to the active stylus.

[0025] S103. Obtain feedback information for the connection request.

[0026] In the embodiment of the present application, when the active stylus obtains the connection request through the first communication mode, it responds to the connection request and sends feedback information to the electronic device through the first communication mode, and the electronic device obtains the feedback information of the active stylus through the first communication mode.

[0027] S104. Establish a data channel with the active stylus based on the feedback information; wherein the data channel with the active stylus is established based on the feedback information before the interaction through the first communication mode, and the data channel with the active stylus is established based on the feedback information through the second communication mode; the first communication mode is used to determine that the active stylus exists and is in an input state, and the first communication mode is different from the second communication mode.

[0028] In the embodiments of the present application, the electronic device can establish a data channel with the active stylus based on the feedback information. The data channel with the active stylus is established to realize more functions of the active stylus in addition to the input operation, such as the function of an air mouse and the function of gesture control operation. For example, a gravity sensor and a gyroscope can be arranged in the active stylus. The active stylus can recognize that the user draws a circle in the air by holding the active stylus, and if the circle corresponds to the meaning of deleting a line, the active stylus can send the instruction of deleting a line to the electronic device through the data channel to realize the operation of deleting a line on the electronic device.

[0029] The information processing method provided in the embodiments of the present application can obtain the device information of the active stylus by sensing that the active stylus is located in the display area of the display screen, send a connection request based on the device information of the active stylus, obtain feedback information for the connection request, and establish a data channel with the active stylus based on the feedback information. Before the data channel with the active stylus is established based on the feedback information, the first communication mode is used for interaction, and the second communication mode is used for interaction after the data channel with the active stylus is established based on the feedback information. The first communication mode is used to determine that the active stylus exists and is in an input state, and the first communication mode is different from the second communication mode. Therefore, the Bluetooth connection between the active stylus and the electronic device can be automatically and quickly established during the input process of the active stylus close to the display screen or in the display area of the display screen, and the user no longer needs to press the button of the active stylus to expand the event, and continuously confirm multiple items. The Bluetooth connection between the active stylus and the electronic device is quickly established without the user's awareness, and the user experience can be improved.

[0030] In an optional embodiment, in step S101, it is sensed that the active stylus is located in the display area of the display screen, and the device information of the active stylus is obtained, including: broadcasting an electrical signal based on a standard frequency; obtaining the electrical signal of the active stylus, demodulating the electrical signal, and obtaining the device information of the active stylus.

[0031] Specifically, the electronic device transmits an electrical signal at a target frequency, but if the electronic device and the active stylus have not established a first communication connection, the electronic device cannot determine the target frequency of the first communication mode. Therefore, the electronic device can broadcast an electrical signal at a standard frequency before the handshake of the first communication mode is successful. The standard frequency is different from the target frequency, and the range of the standard frequency includes the range of the target frequency. If the active stylus receives the electrical signal broadcasted by the electronic device and analyzes it, and then encodes the device information and transmits the electrical signal to the electronic device, the electronic device can obtain the electrical signal of the active stylus, and by analyzing the electrical signal, the device information of the active stylus can be obtained.

[0032] In the embodiment of the present application, the broadcasting is based on the standard frequency electrical signal, so that when the active stylus is located in the display area of the display screen, the electrical signal of the active stylus can be obtained, and the device information of the active stylus can be quickly obtained.

[0033] In an optional embodiment, if it is required to quickly establish the data channel with the active stylus, when the connection request is sent based on the device information of the active stylus in step S102, the connection request can be directly sent to the active stylus based on the standard frequency through the first communication mode in the process of establishing the first communication connection.

[0034] In an optional embodiment, the information processing method further comprises: determining a target frequency of the first communication mode based on the device information; and scanning based on the target frequency to obtain the electrical signal emitted by the active stylus based on the target frequency.

[0035] Specifically, since the active stylus emits the electrical signal based on the target frequency, when the electronic device scans based on the standard frequency, the electrical signal emitted by the active stylus based on the target frequency cannot be obtained in real time, and the electrical signal of other active stylus or user's finger can be received, thereby causing interference to the electrical signal of the active stylus. For example, when a user uses an active stylus to input information on a display screen, if another user uses another active stylus to input information on the display screen at the same time, if the electronic device scans based on the standard frequency, the electrical signals of the two active styluses can be received at the same time. Therefore, in order to resist interference, after the handshake of the first communication mode, the target frequency of the first communication mode can be determined based on the device information, and then scanning can be performed based on the target frequency to reduce the interfering electrical signal. Specifically, the target frequency corresponding to the device information can be queried from a preset frequency table. Then, scanning based on the target frequency can ensure that the electrical signal emitted by the active stylus can be obtained in real time.

[0036] In the embodiment, scanning based on the target frequency can make the frequency scanned by the electronic device consistent with the frequency at which the active stylus transmits the electrical signal, so that the electrical signal transmitted by the active stylus can be received in real time, and at the same time, the interfering electrical signal can be reduced, and accurate matching with the active stylus can be achieved.

[0037] In an optional embodiment, if the electrical signal interference of the active stylus is reduced, when the connection request is sent based on the device information of the active stylus in step S102, the target frequency of the first communication mode can be determined based on the device information after the first communication connection is established, and then the connection request can be sent to the active stylus based on the target frequency through the first communication mode.

[0038] In an optional embodiment, the information processing method further comprises: obtaining the notification information representing the existence of the active stylus and the input state of the active stylus by demodulating the electrical signal obtained by the first communication mode; obtaining the input position of the active stylus by the sensing unit of the display screen based on the notification information; and displaying the trajectory of the active stylus based on the input position.

[0039] Specifically, when the active stylus is close to or writes on the display screen of the electronic device, the electronic device and the active stylus can interact based on the first communication mode. The active stylus can encode the notification information representing the existence of the active stylus and the input state of the active stylus, and send the notification information to the electronic device through the electrical signal. After the electronic device receives the electrical signal, the electronic device can obtain the notification information representing the existence of the active stylus and the input state of the active stylus by analyzing the electrical signal. The notification information can be ×× (device information) in. When the active stylus exists and is in the input state, the electronic device needs to obtain the input position of the active stylus in real time. Since the active stylus itself does not have a sensing unit that can be used to sense the input position on the display screen, after the electronic device obtains the notification information representing the existence of the active stylus and the input state of the active stylus, the electronic device needs to call the sensing unit of the display screen to obtain the input position of the active stylus, and then display the trajectory of the active stylus based on the input position.

[0040] In the embodiments of the present application, after obtaining the notification information representing the existence of the active stylus and the input state of the active stylus, the input position of the active stylus is obtained based on the notification information through the sensing unit of the display screen, and the trajectory of the active stylus is displayed based on the input position. Therefore, the trajectory of the active stylus can be displayed on the display screen in real time, and the purpose of inputting information on the display screen of the electronic device by the active stylus is achieved.

[0041] In an optional embodiment, the step S102 of sending the connection request based on the device information of the active stylus comprises: sending the connection request based on the device information of the active stylus based on the time interval between the notification information.

[0042] Specifically, in an implementation, the active stylus sends the notification information to the electronic device at a certain time interval during continuous input, and the electronic device also obtains the notification information at the time interval. Therefore, the connection request can be sent based on the device information of the active stylus based on the time interval between the notification information during continuous input of the active stylus.

[0043] In another implementation, the active stylus can identify its displacement and send a notification message to the electronic device. For example, when the active stylus is placed on the display screen and there is no relative displacement, the active stylus does not send a notification message to the electronic device. Thus, the active stylus does not send a notification message to the electronic device during the pause time between the current input and the next input, i.e., during the time interval. During the time interval when the user is waiting for input, the electronic device also does not receive a notification message. Therefore, the electronic device can send a connection request based on the device information of the active stylus during the time interval when it is waiting for a notification message.

[0044] In the embodiments of the present application, the electronic device sends a connection request based on the device information of the active stylus based on the time interval between notification messages. This can automatically and quickly establish a Bluetooth connection between the active stylus and the electronic device during the input of the active stylus on the display screen. Thus, the user does not need to pay attention to whether the data channel is connected during the use of the active stylus. This realizes the connection of the data channel between the active stylus and the electronic device without the user's awareness, and improves the user experience.

[0045] In an optional embodiment, the step S102 of sending a connection request based on the device information of the active stylus includes: determining whether the active stylus supports the second communication mode based on the device information of the active stylus; if the active stylus supports the second communication mode, sending a connection request; or / and, determining whether the active stylus is a new device based on the device information of the active stylus; if the active stylus is a new device, sending a connection request.

[0046] Specifically, after obtaining the device information of the active stylus, the support of the second communication mode corresponding to the device information can be queried from the preset information table. If the second communication mode corresponding to the device information is supported, the active stylus supports the second communication mode, and a connection request can be sent to the active stylus through the first communication mode. If the second communication mode corresponding to the device information is not supported, the active stylus does not support the second communication mode. If the active stylus does not support the second communication mode, it is not necessary to send a connection request to the active stylus. For example, if the active stylus supports Bluetooth function, a connection request is sent to the active stylus to establish a Bluetooth connection with the active stylus. If the active stylus does not support Bluetooth function, even if a connection request is sent, a Bluetooth connection cannot be established.

[0047] When the device information of the active stylus is acquired, it can be determined whether the device information of the active stylus exists in a device information table maintained by the electronic device, and the device information maintained in the device information table corresponds to devices that have established a second communication connection with the electronic device. If it is determined that the device information of the active stylus does not exist in the device information table, the active stylus is a new device, and in order to establish a data channel with the active stylus, a connection request can be sent to the active stylus through the first communication mode. If it is determined that the device information of the active stylus exists in the device information table, the active stylus has established a second communication connection with the electronic device, and therefore, before the device information is acquired, the electronic device can have established a second communication connection with the active stylus, and therefore, if the active stylus is an old device, the connection request is not sent.

[0048] In the embodiments of the present application, the judgment of whether the active stylus supports the second communication mode and / or the judgment of the new device based on the device information of the active stylus can save the sending of the connection request in unnecessary cases, and can save the resources of the electronic device.

[0049] In an optional embodiment, the first electric signal of the target frequency is emitted based on the position of the active stylus in the display area of the display screen to send the connection request, and the second electric signal of the target frequency is obtained based on the position of the active stylus in the display area of the display screen to obtain the feedback information.

[0050] Specifically, if the display area of the display screen is particularly large, if the active stylus is in the edge area of the display area, the first electric signal emitted by the display screen can not be received by the active stylus, or the second electric signal emitted by the active stylus can not be received by the electronic device, and therefore, in order to effectively send the connection request and obtain the feedback information, the position of the active stylus in the display area of the display screen can be sensed by the sensing unit. Then the first electric signal of the target frequency is emitted to the position of the active stylus to send the connection request, and the second electric signal of the target frequency is received at the position of the active stylus to obtain the feedback information.

[0051] In the embodiments of the present application, the first electric signal of the target frequency is emitted based on the position of the active stylus in the display area of the display screen, and the second electric signal of the target frequency is obtained, which can reduce the situation of invalid connection request and unable to receive feedback information due to the display area of the display screen being too large, and improve the effectiveness and accuracy of establishing the second communication mode.

[0052] The embodiments of the present application also provide an electronic device, as shown in the figure, comprising a display screen 30 and a processor 31. Figure 2

[0053] ​The display screen interacts with the active stylus through a first communication mode (i.e., the protocol of the active stylus such as UIS or MPP2.0) at any position where the active stylus contacts or closely contacts the display area of the display screen. During the process of determining the trajectory input of the active stylus to the display screen or the time interval of pausing the trajectory input of the active stylus to the display screen, the Bluetooth request is still sent through the first communication mode, and the Bluetooth configuration information fed back by the active stylus to the Bluetooth request is obtained through the first communication mode, so as to quickly establish the communication channel of the second communication mode, such as the Bluetooth channel, without the user's participation in the complex pairing setting process, thereby improving the use efficiency of the active stylus and the user's use experience. The electronic device with the display screen can obtain the data generated by the gravity sensor of the active stylus for determining the gesture input (e.g., the air gesture) of the active stylus through the second communication mode, or the electronic device with the display screen can obtain the sensing data of the active stylus in the air mouse mode generated by the gravity sensor of the active stylus through the second communication mode.

Examples of the above network include but are not limited to the Internet, an intranet, a local area network, a mobile communication network, and combinations thereof.
