AR Glasses Navigation via Location Identifiers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In fulfillment centers, workers face challenges in efficiently navigating to retrieve or store items due to the lack of effective location-specific guidance and real-time task instructions, leading to inefficiencies in order fulfillment and inventory management.
Innovation Solution
The implementation of augmented reality glasses that provide a wearable computing device with a user interface overlaying the field of view, using location identifiers such as barcodes or QR codes to offer turn-by-turn directions and specific instructions based on the worker's location, enabling real-time updates as they move through the center.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If workers navigate fulfillment centers using traditional methods without location-specific guidance, then device complexity is reduced, but productivity decreases due to navigation inefficiencies and time loss
Solution Approach 1:
The patent introduces location identifiers (barcodes, QR codes) as intermediaries placed throughout the fulfillment center. These identifiers mediate between the worker's position and the navigation system, providing simple visual cues that guide workers to their destinations without requiring complex navigation algorithms or expensive equipment. The location identifiers act as a mediator that translates complex spatial relationships into simple, actionable visual information.
Solution Approach 2:
The patent replaces traditional mechanical navigation aids (physical signs, manual directions) with an optical system using augmented reality glasses and visual overlays. The AR display projects directional arrows and location information directly into the worker's field of view, substituting mechanical navigation methods with optical information delivery that is more efficient and less cumbersome.
2Measurement precision
If workers receive real-time location-based instructions through augmented reality glasses, then navigation precision is improved, but device complexity increases due to wearable computing requirements
Solution Approach 1:
The augmented reality glasses serve multiple functions: they capture images of location identifiers, process the visual information, display directional guidance, and provide task instructions. By consolidating these multiple functions into a single wearable device, the system achieves high location accuracy without proportionally increasing complexity. The device acts as a universal tool that handles navigation, identification, and information display simultaneously.
Solution Approach 2:
The system uses the worker's own field of view as the display medium. The AR glasses project information directly onto lenses that the worker already wears, eliminating the need for separate display devices. The worker's natural vision becomes part of the information delivery system, reducing overall device complexity while maintaining high precision location guidance.
3Loss of time
If traditional navigation methods are used in fulfillment centers, then ease of operation is maintained with simple tools, but loss of time increases due to navigation errors and inefficiencies
Solution Approach 1:
The system pre-calculates and displays the optimal navigation path to the worker's destination before the worker begins moving. The AR display shows directional arrows and anticipated route information in advance, allowing the worker to follow a predetermined efficient path without making navigation decisions along the way. This preliminary action eliminates time-wasting navigation errors while keeping the operation simple—workers just follow the pre-planned visual guidance.

AI summary
Disclosed are various implementations for updating information displayed in a user interface for a worker in a fulfillment center. Information changing relative to a previous user interface can be provided in response to location data that indicates the worker's location within a fulfillment center.
