AR Navigation Using Physical Markers for Location Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current augmented reality directional systems lack effective means to determine the location of the device displaying directions or the destination, making it difficult for users to navigate to their intended targets, such as finding goods in a store or locating a vehicle in a parking lot.
Innovation Solution
A computer-implemented method using physical markers, such as QR codes, to authenticate users and determine the location of vehicles or destinations, allowing for the generation and display of augmented reality indicators that guide users through a path to their desired location, utilizing a server and mobile devices to communicate with smart key storage devices and vehicle systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If augmented reality directional systems are implemented without physical markers, then the system appears more advanced and user-friendly, but the system cannot accurately determine the location of the device or destination
Solution Approach 1:
Physical markers serve as intermediary objects between the AR system and the real-world environment. These markers (QR codes, barcodes, or custom images) are placed at specific locations and act as reference points that the device camera can detect and use to calculate precise location and orientation data, enabling accurate AR directional guidance.
Solution Approach 2:
The system creates a digital copy of physical marker information and uses it to determine real-world location. By capturing images of physical markers with the device camera and processing their visual data, the system translates physical world positions into digital coordinate information that drives the AR directional display.
2Measurement precision
If physical markers are used to determine location, then accurate location detection is achieved, but the system complexity increases due to marker authentication and processing requirements
Solution Approach 1:
The physical markers serve multiple functions simultaneously: they act as location identifiers, orientation references, and authentication tokens. This multi-functionality reduces the need for separate systems for each purpose, thereby managing complexity while maintaining high measurement precision.
Solution Approach 2:
The markers are designed to be self-contained with embedded identification information that automatically provides location and authentication data when detected. The system processes the marker information through automated image recognition and coordinate calculation algorithms, minimizing manual intervention and reducing operational complexity.
3Measurement precision
If the system processes location data continuously to provide updated directions, then navigation accuracy is maintained, but energy consumption increases
Solution Approach 1:
Instead of continuous processing, the system periodically updates location data by detecting new physical markers in the environment. The AR directional display refreshes when the device detects a marker change or after a predetermined time interval, reducing energy consumption while maintaining navigation accuracy through event-driven updates.

AI summary
Aspects described herein may allow for displaying augmented reality directions utilizing physical markers. Systems and methods described herein may allow a device to scan to provide augmented reality directions using one or more physical markers as reference points. One or more physical markers may be left along a path, and directions may be provided from one physical marker to the next. A device, such as a mobile device, may be used to scan the physical markers and/or display the augmented reality directions on a display overlaid over a depiction of the surrounding environment.
