AR Glasses for Mail Sorting Using Image Hashing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for sorting physical mail items are labor-intensive, prone to errors, and unable to handle changes in sort locations, leading to incorrect sorting, especially in high-volume environments.
Innovation Solution
The implementation of Augmented Reality (AR) glasses with image recognition capabilities that acquire images of mail items, generate unique identifiers, and provide users with sorting information to guide them to correct sort locations, allowing for real-time adjustments and reducing manual errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual reading and sorting of mail items is used, then labor intensity is high, but sorting accuracy can be maintained through human judgment
Solution Approach 1:
The patent replaces manual mechanical reading and sorting with an automated system using image recognition technology. The wearable device captures images of mail items and uses optical character recognition to extract recipient information, automatically determining sort locations without human intervention, thus increasing both speed and accuracy.
Solution Approach 2:
The system enables mail items to be automatically identified and sorted through machine vision technology. The wearable device autonomously captures images, processes recipient information, and guides sorting decisions without requiring manual reading, allowing the system to serve itself in the sorting process.
2Adaptability or versatility
If manual sorting processes are used, then flexibility to handle sort location changes is poor, but process simplicity is maintained
Solution Approach 1:
The patent implements a dynamic sorting system where sort locations are not fixed but can be updated in real-time. The wearable device receives updated sort location information and adjusts the guidance accordingly, allowing the system to adapt to changing sort requirements without manual reconfiguration.
Solution Approach 2:
The system incorporates feedback mechanisms where the wearable device continuously receives updated sort location information and adjusts its guidance output. This feedback loop ensures that sort location changes are immediately reflected in the sorting process, enhancing adaptability to dynamic conditions.
3Measurement precision
If image recognition technology is implemented, then sorting accuracy improves, but device complexity increases
Solution Approach 1:
The wearable device is designed as a multi-functional system that combines image capture, optical character recognition, image processing, and augmented reality display capabilities in a single device. This universal approach allows the device to perform multiple sorting-related functions without requiring separate specialized equipment for each task.
Data Source
AI summary
An approach is provided for performing sorting of physical mail items using Augmented Reality (A/R) glasses. A/R glasses acquire an image of a physical mail item to be sorted and generate image data that represents the image. A unique value is generated for the image, for example, by processing the image data for the image using one or more hash functions to generate a hash value. The hash value is used to obtain sorting information for the mail item from a mail item manager. The A/R glasses use the sorting information to assist the user in sorting the mail item by displaying the name of a sort location for the mail item, visually distinguishing the sort location from other sort locations, displaying information about the mail item, providing “out of view” assistance, etc. The A/R glasses may allow the user to override the sort location specified for the mail item and override information is sent to the mail item manager.
