Solution Overview

Problem

Current information sharing technologies, such as screen sharing, suffer from network delays and decompression distortions, leading to poor user experience due to the inability to indicate the current information position of the sharer client, making it difficult for the shared client to perceive the sharing process and mode.

Innovation Solution

An information indicating method and apparatus that acquires first and second position parameters of target information on the sharer and shared clients, respectively, to determine an indication identifier, allowing the shared client to indicate the current position of the sharer client, thereby improving user experience.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If screen sharing technology is used for information sharing, then information can be transmitted between clients, but network delays and decompression distortions occur leading to poor user experience

Engineering Contradiction:
Improveinformation sharing qualityVSAvoidnetwork delay
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent uses position parameters to create a simplified copy of the sharer's information state rather than transmitting the actual information content. By sharing only position data (coordinates, scroll position, selection state) instead of full screen content, the system achieves real-time synchronization without network delays or compression artifacts.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent transforms the information sharing problem from transmitting content data to transmitting position parameters. By changing what is being shared from actual information content to positional metadata (x, y coordinates, scroll positions, selection ranges), the system eliminates network delay and distortion issues while maintaining real-time feedback.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If screen sharing technology is used for information sharing, then information can be transmitted between clients, but decompression distortions occur leading to poor user experience

Engineering Contradiction:
Improveinformation sharing qualityVSAvoidimage fidelity
Core Design Contradiction:
ReliabilityVSManufacturing precision

Solution Approach 1:

The patent creates a positional copy rather than a visual copy. Instead of compressing and transmitting screen images that suffer from decompression distortion, the system transmits position parameters that exactly represent the sharer's information state, eliminating fidelity loss entirely.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent replaces the mechanical screen sharing system (capture-compress-transmit-decompress-display) with an information-based system that transmits position parameters. This substitution eliminates the compression-decompression chain that causes image fidelity degradation.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Ease of operation

If position parameters are acquired and indication identifiers are determined to show sharer's information position, then user sharing experience is improved, but system complexity increases

Engineering Contradiction:
Improveuser sharing experienceVSAvoidsystem complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent introduces an indication identifier as an intermediary element that bridges the sharer and shared clients. This identifier synthesizes position parameters into a user-friendly visual indicator, improving user experience while encapsulating the complexity within a standardized interface layer.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent transforms complex position parameters (coordinates, scroll positions, selection states) into simplified indication identifiers that are easy for users to understand. By changing the representation from raw data to user-friendly indicators, the system improves ease of operation while managing complexity through parameter transformation.

Inventive Principle:
Principle #35Parameter changes

AI summary

The embodiments of the disclosure discloses an information indicating method and apparatus, an electronic device and a storage medium, where the method includes: acquiring a first position parameter of first target information in a current page, where the current page is a page in a shared file shared by a sharer client; acquiring a second position parameter of second target information in a display page of the sharer client; and determining an indication identifier according to the first position parameter and the second position parameter, and indicating the second target information according to the indication identifier. When displaying a same shared file as a sharer client at the same time, a shared client can acquire the first position parameter of the first target information of the current page, receive the second position parameter of the second target information in the display page of the sharer client, and determine a relative position of the two target information according to the two position parameters, so that the second target information of the sharer client can be indicated, and the user sharing experience is improved.
