A touch-control object identification method, a touch-control device and a storage medium. The method comprises: after it is detected that a touch-control object touches a touch-control screen, determining a touch-control area corresponding to the touch-control object (110); acquiring a sensing value corresponding to a sensing position comprised in the touch-control area (120); and determining the type of the touch-control object according to the sensing value of the sensing position comprised in the touch-control area (130). After a touch-control object touches a touch-control screen, a change in a sensing value in a touch-control area can usually be detected. Compared with sensing values at other positions, the sensing value in the touch-control area is larger and also more obvious. Sensing values generated after different touch-control objects touch the touch-control screen have a larger difference. Therefore, determining the type of a touch-control object according to the sensing value at a sensing position in the touch-control area is more accurate.

Provided in the present application are an NFC-based screen transmission device connection method and apparatus, and a computer device. The method comprises: when a user touches an NFC tag by using a terminal that has an NFC function, a terminal system identifying whether the NFC tag contains network information of a screen transmission device; and if the NFC tag contains the network information of the screen transmission device, acquiring the network information, and performing connection with the screen transmission device according to the network information. In the present application, after reading network information of a screen transmission device by means of an NFC function, a terminal system directly performs wireless connection with the screen transmission device according to the network information. During the whole connection process, a user only needs to touch an NFC tag by using a terminal, and the operation is simple, convenient and rapid.

The present application relates to the technical field of stylus pens, and provides a stylus pen, an intelligent interactive panel and intelligent blackboard having the stylus pen, and an interactive operation method based on the stylus pen. The stylus pen specifically comprises a pen body; two opposite ends of the pen body in the length direction thereof are respectively provided with a first writing portion and an abutting portion; the cross-sectional area of the first writing portion gradually increases from the end of the first writing portion distant from the pen body to the end of the first writing portion close to the pen body, so that the touch projection area can be changed; the abutting portion is used for abutting against the palm as a support when a user holds the stylus pen; the length of the pen body is 50-100 mm. Thus, the stylus pen is closer to an educational scene, and brings better holding and writing experience to users. Moreover, the above-mentioned interactive operation method can be used to distinguish different function types according to different touch projection areas, so as to provide more realistic writing experience for users, and repeated setting operations when the users want to implement other writing functions during writing are avoided, thereby improving user experience.
