A method for communicatively connecting to a selected display apparatus, a mobile apparatus, and an automatic communicative connection system are disclosed. The mobile apparatus drives a positioning chip to scan with multiple signal emission angles within a preset range. When a single display apparatus is scanned within the preset range, the mobile apparatus selects the single display apparatus as the selected display apparatus. When multiple display apparatuses are scanned within the preset range, the mobile apparatus selects one of the display apparatuses as the selected display apparatus according to multiple corresponding distances respectively between the display apparatuses and the mobile apparatus as well as the signal emission angles corresponding to the display apparatuses with the mobile apparatus. After the selected display apparatus is determined, the mobile apparatus is communicatively connected with the selected display apparatus.

A display system, a display device and an unlocking method thereof are disclosed. The display system includes a user terminal device, the display device and a server. The display device obtains location information and a user identification code according to an ultra-wideband signal. The display device determines whether the location information matches a preset condition. The display device sends a verification request signal including the user identification code to the server. The server receives the verification request signal and executes a verification process to verify the user identification code to generate a verification result. The server sends the verification result to the display device. A screen of the display device is unlocked.

A display device calibration system, a display device calibration method and a storage medium are provided. The system includes an electronic device and a display device. The electronic device includes a first processor and a camera. The display device includes a second processor and a plurality of display modules. The first processor obtains a first image of a part of the display modules and analyzes the first image to determine a target single color value and a reference single color value. The first processor obtains an estimated value according to the target single color value and the reference single color value and determines whether the estimated value is within a predetermined range. The first processor provides a correction signal to the display device when the estimated value is not within the predetermined range, and adjusts the target single color value until the estimated value is within the predetermined range.

Provided are a meeting minutes generation system, a non-transitory processor-readable storage medium, a terminal device, and a meeting minutes generation method thereof. The meeting minutes generation method includes the following. Meeting data is processed and transcript data is generated by a meeting minutes processing module. The transcript data is analyzed to generate meeting minutes data including at least one keyword through the meeting minutes processing module. The meeting minutes data is provided for displaying the meeting minutes data.

A handwriting system including a teaching device and a practicing device is provided. The teaching device is communicatively connected to a network and displays a setup interface which includes a setup window for obtaining practice settings. These practice settings are then transmitted to the network. The practicing device is communicatively connected to the network and displays a user interface for obtaining handwriting information which is transmitted to the network. The practicing device receives an inspection result from the network and displays a feedback message according to the inspection result. A handwriting method and a non-transitory processing device-readable medium are also disclosed.

A remote interaction method and a remote interaction system are provided. The remote interaction method includes: displaying a first interactive interface through a first electronic apparatus; inputting management account data through the first electronic apparatus to log in to the first interactive interface; setting content information according to a user operation through the first interactive interface; transmitting the content information through the first electronic apparatus; receiving the content information through a second electronic apparatus; displaying a second interactive interface through the second electronic apparatus; and displaying the content information through the second interactive interface.

A remote control method and a remote control system are provided. A main block page is displayed through a management apparatus. In response to the management apparatus performing a behavior change on a first object on the main block page, a control instruction is sent through the management apparatus. A sub-block page is displayed through a controlled apparatus. The main block page and the sub-block page have a linkage relationship, and the sub-block page includes a second object associated with the first object. In response to the controlled apparatus receiving the control instruction, the behavior change is performed on the second object on the sub-block page.

A collaboration system and a collaboration method are provided. The collaboration system includes a first display device and a second display device. The first display device includes a first screen. The first screen displays a first display interface. The first display interface has a first display window and a first function key. The first display window displays a first frame. The second display device includes a second display screen. The second display screen displays a second display interface. The second display interface has a second display window. The second display window displays a second frame. When the first function key is turned on, the first frame moves along with the second frame. When the first function key is turned off, the first frame does not follow the movement of the second frame.

A multimedia system and an image display method are provided. The multimedia system includes a processing unit, an input unit, and a display unit. The input unit provides input data. The processing unit communicatively connects to the input unit, and the processing unit generates an operation instruction according to the input data, and generates a composite image. The display unit communicatively connects to the processing unit and displays a selection interface and the composite image. The composite image includes a three-dimensional avatar image and a display content. The processing unit determines a position of the three-dimensional avatar image relative to the display content according to a selection result of the selection interface, and the processing unit adjusts the three-dimensional avatar image according to the operation instruction.

A learning system and an execution method thereof are provided. The execution method includes: displaying an option object through a graphical user interface of a display device, wherein the option object includes at least one option, and the at least one option is associated with course information; in response to one of the at least one option being selected, the graphical user interface displaying a user image and a virtual object; in response to the virtual object being triggered, the graphical user interface displaying a function window, and the function window at least partially overlapping with the user image, wherein the function window has at least one learning option; in response to one of the at least one learning option being triggered, the graphical user interface displaying a question-and-answer window; the question-and-answer window of the graphical user interface displaying a templated answer corresponding to the input data.
