Terminal Keyboard Interaction via Shared Screen Escape Table
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication technologies for remote education and terminal interactions primarily offer limited one-way propagation of audio and video, making it difficult for receivers to clearly understand the practical operations of senders.
Innovation Solution
A method and device that acquire and display indication information of operated keys along with their meaning on a shared screen, allowing senders to share keyboard operations with receivers, enhancing interaction and understanding during remote education.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If audio and video propagation is used for remote education, then communication between terminals is established, but propagation effects are poor and receivers cannot clearly understand sender operations
Solution Approach 1:
The patent segments the operation information into two distinct parts: indication information (identifying which key was pressed) and key meaning information (explaining what the key does). This segmentation allows each type of information to be transmitted and processed separately, ensuring that receivers get both the factual data of key presses and the contextual meaning, thereby resolving the information loss problem in traditional audio-video propagation
Solution Approach 2:
The patent introduces a keyboard escape table as an intermediary component that maps indication information to key meaning information. This intermediary structure enables the system to translate raw keyboard input data into meaningful operational descriptions that receivers can understand, significantly improving propagation effects without relying solely on audio-video transmission
2Loss of information
If only audio and video are transmitted, then one-way propagation is achieved, but receivers cannot directly know practical operations of senders
Solution Approach 1:
The patent implements a feedback mechanism where the sender's keyboard operations are captured, processed into both indication and meaning information, and transmitted back to receivers. This feedback loop allows receivers to directly observe and understand the sender's practical operations in real-time, transforming one-way audio-video propagation into an informative interactive experience that enhances operation clarity
Solution Approach 2:
The patent replaces the mechanical audio-video transmission system with an information-based transmission system. Instead of relying on senders to verbally describe or visually demonstrate operations through video, the system automatically captures keyboard input data, processes it through the keyboard escape table, and transmits the structured information directly to receivers, making operation understanding more direct and efficient
Data Source
AI summary
A method and device for interaction between terminals are described. The method includes that: a keyboard operation message is received (S101); indication information of a corresponding operated key is acquired according to the keyboard operation message (S102); key meaning information corresponding to the indication information is acquired according to a preset keyboard escape table (S103); the indication information and the corresponding key meaning information are displayed in a shared screen (S104); and the contents displayed in the shared screen are sent to a target terminal when a sharing request of the target terminal is received (S105). According to the embodiment of the method and the device, a sender sends both information of indicating an operated key and corresponding key meaning information to the receiver, and compared with an existing manner of only providing limited one-way propagation, such a manner has the advantages that the receiver may clearly and directly know a practical operation of the sender, and propagation effects between the terminals may be improved.
