AR Information Provision via Position-Based Pre-Fetching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional augmented reality (AR) information provider systems using mobile communication terminals are inefficient due to the need for real-time data retrieval from servers, limited storage capacity, and inability to cater to users' diverse tastes with a single tag pattern.
Innovation Solution
A method and apparatus that enable quick provision of AR information by sending an AR information request with position information, receiving and storing AR data associated with tag patterns in mobile communication terminals, and using a server to classify user information for tailored AR data transmission based on user interests and location.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If real-time server retrieval is used to provide AR information, then information freshness is improved, but information provision speed deteriorates due to network latency
Solution Approach 1:
The system performs preliminary actions by predicting which AR information the user will need based on current location and movement direction, and pre-fetches this information from the server before the user actually requests it. This eliminates the network latency delay when the user views the tag, as the information is already cached in the terminal.
Solution Approach 2:
The system dynamically adjusts the information retrieval strategy based on user context. It continuously monitors user location, movement direction, and viewing behavior to adaptively predict future information needs and adjust pre-fetching parameters, optimizing the balance between information freshness and provision speed.
2Loss of information
If comprehensive AR information is stored in mobile terminal, then information availability is improved, but storage capacity is exceeded
Solution Approach 1:
Instead of uniformly caching all AR information, the system applies local quality by selectively caching only the specific portions of information that are predicted to be relevant to the user's current and near-future needs, based on location, direction, and user profile.
Solution Approach 2:
The system changes the parameter of information selection by using multiple prediction parameters (location, movement direction, user interests, time of day) to dynamically determine which information to cache, rather than using a fixed caching strategy.
3Device complexity
If same tag pattern provides same information to all users, then system complexity is reduced, but user personalization capability deteriorates
Solution Approach 1:
The system performs preliminary classification of users into interest groups before information delivery. User profiles and preferences are pre-analyzed and stored, enabling the system to quickly retrieve and deliver personalized information without complex real-time processing.
Solution Approach 2:
Instead of creating entirely separate information sets for each user, the system uses copying with personalization - it copies the base AR information from the server and then overlays user-specific filters and preferences based on their interest group classification.
4Quantity of substance
If AR information is fetched on-demand from server, then storage requirements are reduced, but information provision speed deteriorates
Solution Approach 1:
The system pre-fetches AR information based on predicted user needs before the user actually requests it. By analyzing current location, movement direction, and user profile, the system proactively retrieves and caches information that the user is likely to view soon, eliminating network latency at the moment of viewing.

AI summary
A system and method for providing augmented reality (AR) information to a mobile communication terminal in a mobile communication system is provided. If the mobile communication terminal is determined to have entered a service cell providing AR information, the mobile communication terminal transmits an AR information request including position information to a server. Upon receiving the AR information request signal, the server determines AR information including at least one tag pattern provided in the service cell and information associated with the tag pattern and transmits the AR information to the mobile communication terminal.
