The present application discloses a screen projection method and apparatus, a device and a storage medium. The method comprises: when a screen projection instruction is received, determining a quantity of devices to be subject to screen projection; determining a target display screen for each device to be subject to screen projection on the basis of an average allocation principle and/or a first-screen-first-projected principle and according to pre-acquired quantities of devices already subject to screen projection and devices to be subject to screen projection on each display screen; and projecting images of each device to be subject to screen projection to the corresponding target display screen.
Provided in the embodiments of the present application are a multi-screen interaction system and a multi-screen interaction device. A first display device and a plurality of second display devices of the multi-screen interaction system are all connected to the multi-screen interaction device, a central control device is connected to the multi-screen interaction device, and the first display device, the second display devices and the central control device are all connected to a switch; the multi-screen interaction device receives a first display signal of a first target device according to a first control signal that is sent by the central control device, and sends the first display signal to a second target device; and the switch sends, to the second target device, a second control signal that is sent by the central control device, and the second target device displays the first display signal according to the second control signal, wherein the first target device is the first display device and the second target device is the second display device, or the first target device is the second display device and the second target device is the first display device. By means of the multi-screen interaction system, the technical problem of it not being possible to take both the number of serial port cables of an intelligent teaching system in a classroom and the effective transmission of a display signal into consideration can be solved.
Embodiments of the present application disclose a PC module and an interactive tablet, the PC module comprising a housing; a PC motherboard, the PC motherboard being located within the housing; a handle, the handle being connected to the housing and exposed outside the housing; and an antenna assembly, the antenna assembly being disposed on the handle and electrically connected to the PC motherboard. In the PC module of the embodiments of the present application, the antenna assembly is disposed on the handle outside the housing of the PC module, and the antenna assembly does not need to be disposed inside the PC module. On the one hand, interference of an electronic component inside the PC module to the antenna assembly is prevented without needing to add a shielding cover; on the other hand, after the PC module is embedded in an electronic device such as an interactive tablet, the handle of the PC module is exposed outside the interactive tablet, the antenna assembly is disposed outside of the interactive tablet, and the antenna assembly does not need to be disposed at the border of the interactive tablet, so that the interactive tablet can achieve a narrow-bezel design or even a bezel-less design.
Embodiments of the present application disclose a writing effect processing method and apparatus, a device, and a storage medium. The technical solution provided in the embodiments of the present application comprises: obtaining a smooth curve according to report point information added to touch point data in a point trace buffer; determining a drawing point trace from the smooth curve; determining a pressure sensing prediction value according to pressure sensing information in touch data; and displaying a corresponding drawing track on a display screen according to the drawing point trace and the pressure sensing prediction value. Thus, jitter of the drawing track during display of the drawing track is reduced, allowing the drawing track to be smoother, and different pressure sensing information will be generated when writing by using writing pens of different materials or by using different writing forces, such that the finally displayed drawing track is closer to an actual writing effect, enriching display effects of the drawing track, improving the selectivity for a user on writing effects, and thus enriching display effects of an interactive tablet when using writing pens of different materials.
Disclosed in the embodiments of the present application are a behavior recording method and apparatus, a behavior playback method and apparatus, a device, and a storage medium. The behavior recording method comprises: after receiving an operation behavior recording instruction, recording an operation behavior for courseware; during a recording process, by means of a page-turning instruction, causing the current display page of the courseware to at least display a first option and a second option; receiving a first selection operation used for selecting the first option; associating the currently recorded first operation behavior with the first option, so as to play back, during an operation behavior playback process, the first operation behavior when the first option is selected; after the first operation behavior is recorded, receiving a second selection operation used for selecting the second option; and associating the currently recorded second operation behavior with the second option, so as to play back, during the operation behavior playback process, the second operation behavior when the second option is selected. By using the method, the technical problem in the related art of when recording is performed according to a time axis, different students being unable to play back different teaching contents in the courseware can be solved.
G06F 3/0488 - Interaction techniques based on graphical user interfaces [GUI] using specific features provided by the input device, e.g. functions controlled by the rotation of a mouse with dual sensing arrangements, or of the nature of the input device, e.g. tap gestures based on pressure sensed by a digitiser using a touch-screen or digitiser, e.g. input of commands through traced gestures
