AR Glasses Mail Sorting with Visual Guidance
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 use of Augmented Reality (AR) glasses equipped with an image acquisition component and a mail sorting application that captures images of mail items, generates unique identifiers, and provides sorting information to assist users in placing items at correct sort locations, allowing for real-time updates and 'out of view' assistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual reading and sorting methods are used, then sorting can be performed with simple equipment, but sorting accuracy deteriorates and error rate increases
Solution Approach 1:
The patent replaces manual mechanical reading and sorting operations with an automated system using image acquisition devices, optical character recognition (OCR), and computer vision algorithms to detect, read, and sort mail items automatically, thereby improving sorting accuracy while reducing human labor
Solution Approach 2:
The patent introduces an intermediary computing system that acts as a mediator between the physical mail items and the sorting mechanism. This system captures images of mail items, processes the visual information through OCR and image recognition, and provides sorting instructions to the sorting mechanism, thereby enabling accurate automated sorting
2Productivity
If manual sorting processes are used, then system complexity remains low, but productivity and sorting speed deteriorate
Solution Approach 1:
The patent replaces slow manual sorting operations with an automated optical recognition system that can rapidly capture images of mail items, process the visual data through OCR and image recognition algorithms, and determine sort locations at high speed, thereby dramatically increasing sorting productivity
Solution Approach 2:
The patent performs preliminary actions by pre-processing images of mail items, extracting recipient information and sort location data before the actual sorting operation. This allows the system to prepare sorting instructions in advance, enabling faster throughput and higher productivity during the sorting process
3Adaptability or versatility
If static sorting information is used, then information management is simple, but adaptability to changing sort locations deteriorates
Solution Approach 1:
The patent implements a dynamic information management system that can adapt to changing sort locations in real-time. The system continuously updates the mapping between recipient information and sort locations, allowing it to respond to changes in the sorting environment without requiring complete reconfiguration, thereby maintaining high adaptability
Solution Approach 2:
The patent incorporates feedback mechanisms where the system continuously monitors the sorting process, compares actual sort locations with expected locations, and adjusts the sorting information accordingly. This feedback loop enables the system to adapt to changes in sort locations and maintain accurate sorting despite environmental variations
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.
