Wearable Camera Barcode Detection for Contactless Transactions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bar code technologies require manual invocation of payment applications and physical proximity to bar code readers for contactless transactions, which can be cumbersome and limit user convenience.
Innovation Solution
A wearable multimedia device equipped with a wide field-of-view camera and processors that can capture and crop bar codes from a scene, establish communication channels, and authenticate transactions without a physical display, allowing for contactless transactions based on user intent.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual invocation of payment application is required, then device complexity is reduced, but ease of operation deteriorates
Solution Approach 1:
The system performs automatic bar code detection and transaction initiation without requiring manual user actions. The wearable device automatically captures the bar code from the display, processes it through the processor, and initiates the transaction, allowing the system to serve itself rather than requiring continuous user intervention.
Solution Approach 2:
The bar code is pre-displayed on the terminal device screen before the transaction occurs. This preliminary display of the bar code allows the wearable device to capture and process it automatically when brought into proximity, eliminating the need for manual invocation at the moment of transaction.
2Productivity
If physical proximity to bar code reader is required, then measurement precision is improved, but productivity deteriorates
Solution Approach 1:
The patent replaces the mechanical proximity-based reading system with an optical capture system. Instead of requiring physical contact or close proximity to a reader, the wearable device uses its camera to capture the bar code optically from the display screen, enabling transactions from a greater distance and improving transaction speed.
Solution Approach 2:
The system transitions from a one-dimensional proximity-based interaction to a two-dimensional visual capture approach. The bar code is captured as an image from the display screen, allowing the system to process transactions based on visual detection rather than physical proximity, effectively adding a spatial dimension to the interaction.
3Ease of operation
If hardware display with bar code is used, then ease of operation is improved, but device complexity deteriorates
Solution Approach 1:
The patent extracts the bar code display function from the wearable device itself and places it on the terminal device screen. The wearable device only needs to capture the externally displayed bar code, eliminating the need for it to have its own display hardware while maintaining the ability to perform contactless transactions.

AI summary
In an embodiment, a wearable multimedia device, comprises: a housing configured to attach to clothing of a user; a wide field-of-view camera embedded in the housing; one or more processors; memory storing instructions that when executed by the one or more processors, causes the one or more processors to perform operations comprising: capturing, using the camera, an image of a scene that includes a bar code displayed by a terminal device; determining an intent of the user to read the bar code; in accordance with the user's intent to read the barcode: cropping the barcode from the image of the scene; establishing, using the bar code, a communication channel with the terminal device; receiving, using the communication channel, transaction data from the terminal device; and responsive to the transaction data, sending, using the communication channel, authentication credentials to the terminal device.
