Dynamic AR Context Access for Mobile GPS Power Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Mobile Augmented Reality (AR) systems face challenges in dynamically managing AR user context access, leading to inefficient power consumption and shortened battery life due to continuous GPS usage and high positioning accuracy requirements, which are not optimized based on user context and service demands.
Innovation Solution
A method for dynamically managing AR user context access by optimizing the positioning accuracy and mode of AR terminal capability components, such as GPS, based on user location, distance to AR Targets, and number of targets to be matched, using a Mobile AR client and server collaboration to adjust terminal context accessing behavior according to demand and status.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If GPS positioning is continuously activated to ensure accurate AR target discovery and content rendering, then positioning accuracy is improved, but power consumption increases significantly
Solution Approach 1:
The patent applies dynamics by making the GPS module's operating state adjustable between different modes (continuous positioning, periodic positioning, and on-demand positioning) based on real-time service requirements and battery status, rather than maintaining a fixed continuous operation state
Solution Approach 2:
The patent changes the operational parameters of the GPS module dynamically, including positioning interval, positioning mode, and access frequency, based on service demand and battery status to optimize the balance between positioning accuracy and power consumption
2Loss of time
If GPS device operates in turned-on state all the time to achieve better Time to First Fixed (TTFF), then positioning response time is improved, but battery life is shortened
Solution Approach 1:
The patent implements periodic action by setting configurable positioning intervals for the GPS module, allowing it to operate in periodic mode rather than continuous mode, thus reducing overall power consumption while still achieving timely positioning updates based on service needs
3Device complexity
If terminal context accessing operation is not dynamically adjusted to meet service demands, then system simplicity is maintained, but power consumption increases due to wasted capability component operation
Solution Approach 1:
The patent applies feedback by continuously monitoring service demand status and battery status, then using this feedback to dynamically adjust GPS module operations, creating a closed-loop control system that optimizes power consumption based on actual needs
Solution Approach 2:
The system performs self-service by automatically adjusting GPS module operations based on monitored service demands and battery status without requiring manual user intervention, enabling dynamic optimization of power consumption

AI summary
Disclosed are methods for accessing an AR user context. A method includes: a Mobile AR client collecting information related to AR user context accessing (S302); the Mobile AR client determining, according to the collected information and a current AR service environment, a demand and/or a status of the AR user context accessing (S304); and the Mobile AR client managing, according to the determined demand and/or status of the AR user context accessing, the AR user context accessing (S306). The present invention solves the problem in the prior art that the AR user context accessing cannot be dynamically managed, thereby achieving the technical effect of dynamically managing the AR context.
