Solution Overview

Problem

Existing SLAM tracking technologies in virtual reality fail to intuitively convey tracking performance in specific environments to general users, relying on numerical results and system events.

Innovation Solution

A tracking performance display method and host that provide visual content in a see-through mode, evaluate tracking performance, and display tracking performance indicators within the visual content, using different visual types to indicate performance states.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If tracking performance is displayed using numerical results and system events, then the information is accurately conveyed, but the intuitiveness for general users deteriorates

Engineering Contradiction:

Improvetracking performance informationVSAvoiduser understanding

Core Design Contradiction:

Loss of informationVSEase of operation

Solution Approach 1:

The patent uses color changes to represent different tracking performance states. Good tracking performance is indicated by a first color (e.g., green), while poor tracking performance is indicated by a second color (e.g., red). This visual encoding allows general users to intuitively understand tracking quality without needing to interpret numerical data or system events.

Inventive Principle:

Principle #32Color changes

Solution Approach 2:

The patent introduces a tracking performance indicator as an intermediary element between the tracking system and the user. This indicator translates complex tracking data into simple visual signals that are easily understood by general users, serving as a bridge between technical performance and user comprehension.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Measurement precision

If detailed tracking performance data is provided, then measurement precision is improved, but device complexity increases

Engineering Contradiction:

Improvetracking performance measurementVSAvoiddisplay system complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The patent extracts only the essential information from complex tracking performance data - the overall tracking quality state - and presents it through a simple visual indicator. By taking out only the critical performance aspect (good/poor tracking state) rather than displaying all detailed metrics, the system maintains measurement precision for tracking evaluation while significantly reducing display complexity.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent segments the tracking performance evaluation into distinct visual states (first color for good performance, second color for poor performance). This segmentation allows the system to present comprehensive tracking information in an simplified, organized manner that is easy to process for users without overwhelming them with complex data.

Inventive Principle:

Principle #1Segmentation
