Example III

Referring to fig. 3, a timing chart of a short-range wireless communication connection method according to a third embodiment of the present invention is shown.

The embodiment describes the short-distance wireless communication connection method provided by the invention in the form of a specific example from the interaction angle of the active pen, the touch screen and the equipment where the touch screen is located.

The short-range wireless communication connection method of the present embodiment includes the steps of:

step S302: the nib of the active pen approaches the touch screen, and a coding signal is sent to the touch screen driver.

In this embodiment, the bluetooth active pen is taken as an example, and the bluetooth active pen integrates a short-range wireless communication function, specifically, a bluetooth function in this embodiment, but the short-range wireless communication function is not limited thereto, and may be an NFC function, a Hotknot function, or other suitable short-range wireless communication functions.

In particular, in this embodiment, the bluetooth active pen is a single device, the pen tip of which can directly interact with other devices such as a touch screen of a notebook computer, and the bluetooth device at the tail end of which can be interconnected with bluetooth of the notebook computer to further realize information interaction. In this embodiment, the bluetooth active pen can also automatically connect the bluetooth device on the pen with the notebook computer, and the active pen is used as the information transmitting end and is responsible for transmitting the relevant information of the bluetooth device on the pen to the touch screen through the pen point.

A touch screen is a component of an electronic device such as a notebook computer that responds to touch events from a variety of mediums such as a hand, pen, etc., and provides coordinate information to an operating system. The touch screen in this embodiment is integrated with a short-range wireless communication function, specifically, a bluetooth function in this embodiment, but the short-range wireless communication function may also be an NFC function or a Hotknot function. In one connection, the short-distance wireless communication functions used by the active pen and the touch screen are the same, such as Bluetooth. In the scheme of the embodiment, the capability of the touch screen that information interaction can be performed with the active pen is effectively utilized, and the touch screen is used as an information receiving end for receiving identification information from the active pen, such as a device identification code, bluetooth information of the active pen and the like.

The pen tip code of the active pen is a near field wireless communication technology of transmitting codes through the pen tip, and in the embodiment, the active pen sends code signals to the touch screen through the technology.

But not limited to the manner of sending the coding signal, the short-range wireless communication connection scheme of the embodiment also supports customizing various gestures in the automatic connection process so as to enrich the operation experience of the user.

For example, the gesture connection mode is adopted to realize the short-distance wireless communication connection between the active pen and the touch screen. For example, when the active pen draws a designated simple graphic, such as drawing a letter "O", on the touch screen, the touch screen will notify the service process of the system service layer of the device where the touch screen is located, the active pen will perform pairing operation, and the service process will acquire the information of the bluetooth device that is currently connected and match with the bluetooth information of the current active pen, and if the information matches with the bluetooth information of the bluetooth device, the active pen is directly displayed on the desktop to be connected. If the matched information is not found, the service process informs the active pen of needing to enter a broadcasting mode through the touch screen, then the service process opens the Bluetooth searching function of the system, finds out the equipment conforming to the Bluetooth information of the active pen in the searched Bluetooth equipment, and then completes the pairing action with the equipment. If the pairing is not completed at the set time T1, a connection failure may be displayed on the desktop. In the whole process, only an active pen is needed to draw a letter O on the touch screen.

For another example, the gesture disconnection mode can also be used for realizing the disconnection of the short-distance wireless communication connection between the active pen and the touch screen. If, for example, a disconnection is desired, the active pen need only draw another designated simple graphic, such as the letter "C". After the touch screen recognizes the graph, a disconnection command is sent to a service process of system service of equipment where the touch screen is located, and the service process automatically disconnects and displays the graph on a desktop according to the acquired Bluetooth information.

In addition, in this embodiment, a touch screen driver of the touch screen is used, so that the touch screen driver is responsible for interaction with a service process of a device where the touch screen is located and a pen point, and sends a request to the pen point and receives various information transmitted by the pen point; and on the other hand, the Bluetooth information on the pen is transmitted to the service process by interacting with the service process.

Step S304: the touch screen driver receives a coding signal sent by the active pen, sends a request message to the active pen, and requests a pen identification code of the active pen.

When the active pen approaches the touch screen, the touch screen driver will learn the event and send a request message to the active pen to request the pen identification code.

Step S306: and after the active pen receives the request message sent by the touch screen driver, transmitting the pen identification code to the touch screen driver.

Step S308: after receiving the pen identification code, the touch screen driver judges whether the touch screen driver is connected with the active pen or not.

Step S310: and the touch screen driver informs a service process of the equipment where the touch screen is positioned under the condition that the touch screen driver is not connected with the active pen, and transmits the identification code to the service process.

The service process is resident on a device where the touch screen is located, such as a notebook computer, and can monitor various information uploaded by the touch screen driver and complete pairing or disconnection operations of bluetooth.

Step S312: the service process determines whether the relevant information of the active pen is stored according to the pen identification code, if yes, the stored bluetooth information is directly used for bluetooth connection, and if no, step S314 is executed.

Step S314: the service process sends a request to the touch screen driver to request bluetooth information of the active pen.

Step S316: the touch screen driver sends a request for bluetooth information to the active pen.

Step S318: after receiving the request, the active pen prepares bluetooth information and switches the pen tip to a connected mode.

Step S320: the active pen sends relevant Bluetooth information to the touch screen driver.

Step S322: the touch screen driver performs information verification on the acquired Bluetooth information, transmits the Bluetooth information to a service process after the verification is passed, and simultaneously sends a stop sign to the active pen.

For example, by checking and judging the data carried in the bluetooth information, whether the acquired bluetooth information is complete or not is checked.

Step S324: after the service process receives the Bluetooth information, the Bluetooth information is recorded, and Bluetooth equipment of equipment where the touch screen is located is opened so as to be connected with the active pen in a Bluetooth mode.

Step S326: the touch screen drive records the connection status.

Step S328: and the pairing operation of the active pen and the equipment where the touch screen is positioned is completed, and Bluetooth connection of the active pen and the equipment where the touch screen is positioned is established.

After the touch screen driver sends the stop flag to the active pen in step S322, the active pen receives the stop flag and switches the pen point back to the operation mode.
