Location Offset Correction for Augmented Reality Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Augmented reality systems for navigation and location services face inaccuracies due to errors in location and orientation data from GPS and compasses, leading to incorrect placement of representations on user devices, which can be confusing for users, especially when features are close together.
Innovation Solution
A system that allows users to specify offset information for location-based features, enabling accurate placement of representations on a location-based display by receiving input for correcting the position and orientation of these features, either manually or automatically, based on sensor data and user feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If GPS and compass data are used for augmented reality location services, then the system can provide location and navigational information, but the location and orientation accuracy deteriorates due to sensor errors
Solution Approach 1:
The system displays the determined location on a map interface and receives user feedback by allowing users to manually adjust the location marker to the correct position. This feedback mechanism enables the system to learn from user corrections and improve location accuracy over time, resolving the contradiction between providing location services and maintaining accuracy.
Solution Approach 2:
The system automatically determines location using sensor data and presents it for user verification. By combining automated self-determination with optional user correction, the system maintains service continuity while improving accuracy when needed, addressing the trade-off between service availability and precision.
2Manufacturing precision
If manual offset correction is allowed for location features, then the placement accuracy of representations improves, but the device complexity increases due to additional input handling
Solution Approach 1:
The system applies offset corrections locally to specific location features rather than requiring global system changes. Users can adjust individual representations on the map interface without affecting other parts of the system, maintaining simplicity while improving local accuracy.
Solution Approach 2:
The system provides manual offset correction as an optional feature rather than a mandatory function. Users can choose to apply corrections only when needed, keeping the system simple for basic operations while enabling enhanced accuracy when users encounter placement issues.
3Measurement precision
If offset information is applied to correct representation placement, then the navigational data accuracy improves, but the ease of operation decreases due to additional manual input requirements
Solution Approach 1:
The system automatically determines and displays location information before offering manual adjustment. This preliminary automated action provides immediate value to users, and the manual offset correction is presented as a subsequent optional refinement rather than a required step, maintaining ease of operation while enabling accuracy improvement.
Solution Approach 2:
The system presents determined location data for user verification and allows corrections only when users identify inaccuracies. This feedback-based approach ensures users interact with the system only when needed, maintaining simplicity for accurate cases while enabling correction when necessary.

AI summary
An approach is provided for determining location offset information. A correction manager determines to present, at a device, a location-based display including one or more representations of one or more location-based features. Next, the correction manager receives an input for specifying offset information for at least one of the one or more representations with respect to the location-based display. Then, the correction manager determines to present the one or more representations in the location-based display based, at least in part, on the offset information.
