Dynamic AR Tag Generation via Azimuth and Location Context
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional augmented reality (AR) services are limited in providing dynamic information as they rely solely on GPS information, failing to change the information displayed when the user's location or azimuth changes, resulting in a static experience.
Innovation Solution
A user equipment and method that captures images of target objects, collects contextual information including location and azimuth data, and generates AR tags based on this information, allowing for dynamic AR information display that changes with the user's perspective, using a combination of photographing, information collection, communication, and display units, and an AR management server to store and manage AR data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional AR service uses only GPS information to provide AR content, then the system complexity is low, but the AR information remains static and cannot adapt to changes in user location or viewing direction
Solution Approach 1:
The patent transforms the static AR information delivery into a dynamic system that automatically adapts to user movement and orientation. The AR server receives real-time location and azimuth data from the mobile terminal, dynamically selects appropriate AR content based on the user's current context, and updates the displayed information accordingly. This dynamic adaptation resolves the contradiction by making the system responsive to user actions while maintaining manageable complexity through automated processing.
Solution Approach 2:
The patent implements a feedback mechanism where the mobile terminal continuously reports location and azimuth information to the AR server, which then adjusts the AR content based on this feedback. The system creates a closed-loop control where user movement and orientation are detected, processed, and used to modify the AR information display in real-time, enabling adaptability without requiring complex manual intervention.
2Loss of information
If AR service provides basic information only, then the information processing is simple, but the user experience lacks richness and engagement
Solution Approach 1:
The patent applies local quality by providing different AR information content based on the user's specific location and viewing direction. Instead of delivering uniform information to all users, the system tailors the AR content to match the local context - showing different information for different objects, locations, or viewing angles. This approach enriches the information provided while keeping processing complexity manageable through context-based selection.
Solution Approach 2:
The patent utilizes parameter changes by varying the AR information delivery based on changing parameters such as GPS coordinates and azimuth angles. As these parameters change with user movement and orientation, the system automatically adjusts the information content, providing a richer and more relevant user experience without requiring complex manual information processing.
3Adaptability or versatility
If AR tag is generated based on multiple contextual parameters including azimuth, then the AR experience becomes dynamic and engaging, but the data processing and storage requirements increase
Solution Approach 1:
The patent applies preliminary action by pre-processing and organizing AR information data on the server side before transmission to the mobile terminal. The AR server maintains a structured database of AR content associated with different locations and azimuth ranges, allowing for efficient retrieval and selection based on user context. This preliminary organization reduces the data processing burden on the mobile device while enabling dynamic AR tag generation.
Solution Approach 2:
The patent introduces an AR server as an intermediary between the user and the AR content database. This intermediary handles the complex tasks of data storage, processing, and selection based on location and azimuth parameters, then delivers only the necessary information to the mobile terminal. The intermediary architecture distributes the data processing load and enables sophisticated AR tag generation without overwhelming the client device.
