Solution Overview

Problem

Current digital map operations fail to effectively utilize and visualize unoccupied three-dimensional spaces, limiting the realization of their value.

Innovation Solution

A method for displaying authorized spaces based on a digital map, which involves obtaining a preview stream of a target scene, identifying authorized spaces corresponding to a user identifier, and rendering these spaces within the preview stream, allowing for the addition and synchronization of media content across multiple authorized spaces.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If digital maps include a large quantity of remaining three-dimensional spaces that are not occupied, then the digital map covers more area, but the value of these three-dimensional spaces cannot be realized

Engineering Contradiction:

Improvecoverage area of digital mapVSAvoidvalue realization of three-dimensional spaces

Core Design Contradiction:

Area of stationary objectVSLoss of information

Solution Approach 1:

The patent segments the three-dimensional space in the digital map into multiple authorized spaces with different access permissions. By dividing the space into authorized and unauthorized regions, the system enables selective content placement and value realization for specific areas while maintaining overall map coverage.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent performs preliminary actions by pre-defining authorized spaces and assigning access permissions before content is added. This advance preparation allows the system to immediately realize the value of three-dimensional spaces when content is introduced, rather than leaving them as unoccupied voids.

Inventive Principle:

Principle #10Preliminary action

2Measurement precision

If multiple authorized spaces are rendered in the preview stream, then the visualization accuracy improves, but the device complexity increases

Engineering Contradiction:

Improvevisualization accuracy of authorized spacesVSAvoidcomplexity of rendering system

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The patent introduces an intermediary layer (the rendering module) that mediates between the digital map data and the preview stream display. This intermediary handles the complex task of rendering multiple authorized spaces with different permissions, shielding the user from the underlying complexity while maintaining visualization accuracy.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent transitions from two-dimensional map representations to three-dimensional authorized spaces within the preview stream. By adding the third dimension and rendering spaces spatially, the system achieves accurate visualization of authorized areas without requiring complex additional hardware, leveraging the existing AR/VR rendering capabilities.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

3Loss of information

If media content is added to authorized spaces, then the value of three-dimensional spaces is realized, but the risk of occupying spaces reserved for other users increases

Engineering Contradiction:

Improvevalue realization of three-dimensional spacesVSAvoidspace reservation accuracy

Core Design Contradiction:

Loss of informationVSReliability

Solution Approach 1:

The patent applies local quality by assigning different access permissions to different authorized spaces. Each space has its own access control settings that determine which users can add content. This localized permission system ensures that media content is added only to appropriate spaces without interfering with spaces reserved for other users, maintaining both value realization and space reservation accuracy.

Inventive Principle:

Principle #3Local quality

4Stability of the object's composition

If content is synchronized across multiple authorized spaces, then the consistency of media content improves, but the time required for synchronization increases

Engineering Contradiction:

Improveconsistency of media contentVSAvoidsynchronization time

Core Design Contradiction:

Stability of the object's compositionVSLoss of time

Solution Approach 1:

The patent implements a feedback mechanism where the system monitors content additions to authorized spaces and automatically propagates changes across related spaces. The synchronization system receives feedback about content changes and triggers updates only when necessary, maintaining consistency while minimizing synchronization time by avoiding unnecessary updates.

Inventive Principle:

Principle #23Feedback

AI summary

Methods, devices, and systems for digital space management in virtual reality and augmented reality are described. A method can include a terminal that logs in to a preset application based on a first user identifier, presents a first interface, where the first interface includes a virtual space registration option. In response to an enabling operation of a user for the virtual space registration option, the terminal photographs a first scene to obtain a preview stream, obtains a target geometry, and sends the first user identifier, the preview stream, and the target geometry to a server. The preview stream and the target geometry are used to determine a target virtual space in which a user with the first user identifier has virtual content editing permission in a first virtual space. The first virtual space is a virtual space corresponding to a real world including the first scene. The target geometry is used to represent a form of the target virtual space.
