AR Guide Animations Using Feature Points to Reduce Scene-Model Workload
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing augmented reality (AR) technologies face challenges in guiding users effectively due to the heavy workload of producing 2D or 3D scene models and the limited field of view (FOV) of AR devices, which results in a poor user experience.
Innovation Solution
An AR guiding method that obtains a real-time surrounding image and determines a guide sign sequence based on the image, displaying guide animations to direct the user's line of sight from one guide sign to the next, thereby improving the user's visual experience without the need for extensive image production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If 2D scene images or 3D scene models are displayed in AR devices to guide users, then users can observe the environment, but the workload of producing these images/models is heavy and the limited FOV occupies most of the display area resulting in poor user experience
Solution Approach 1:
The system automatically detects feature points in the real environment and generates guide signs without requiring manual production of 2D/3D scene models. The AR device captures the current scene, identifies natural feature points, and creates guidance annotations based on these detected features, eliminating the need for pre-produced scene models
Solution Approach 2:
The patent transitions from displaying comprehensive 2D/3D scene models that occupy the entire FOV to overlaying minimal 2D guide signs directly on the real-world view. This dimensional approach allows guidance information to be integrated into the natural scene without blocking the user's view of the environment
2Measurement precision
If 2D scene images or 3D scene models are displayed in AR devices, then scene recognition can be guided, but the limited field of view is occupied resulting in poor user experience
Solution Approach 1:
Instead of displaying comprehensive scene models across the entire FOV, the system places targeted guide signs only at specific feature points that require user attention. Each guide sign is localized to its corresponding feature point position, providing precise guidance without occupying unnecessary display area
Solution Approach 2:
The guidance system divides the scene into discrete feature points and assigns individual guide signs to each point. This segmentation allows the guidance information to be distributed across multiple locations rather than presenting a single large-scale 2D/3D model that would dominate the entire field of view

AI summary
An augmented reality (AR) guiding method applied to an AR device includes: obtaining a real-time surrounding image and a focus of a user's line of sight in the real-time surrounding image; determining a guide sign sequence based on the real-time surrounding image; and displaying at least one guide animation based on the guide sign sequence, each guide animation being used to guide the focus of the user's line of sight from a current guide sign to a subsequent guide sign.
