Visual Device Identification for Intuitive Data Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current data transfer methods between computing devices require manual selection of destination devices, which can be cumbersome and require knowledge of identification information, making it difficult for users to transfer files intuitively and efficiently.
Innovation Solution
The system uses graphically encoded display elements on computing devices that are uniquely identifiable through image acquisition, allowing users to transfer data by pointing one device at another, eliminating the need for manual selection and identification information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual selection of destination devices is used for data transfer, then device identification accuracy is improved, but ease of operation deteriorates
Solution Approach 1:
The patent replaces manual mechanical selection operations with an automated optical recognition system. The image acquisition component captures visual information of display elements, and the system automatically identifies the destination device through image processing, eliminating the need for manual device selection while maintaining identification accuracy.
Solution Approach 2:
The destination device presents a graphically encoded display element that automatically identifies itself. The source device's image acquisition component captures this self-presented visual identifier, enabling the system to perform device identification autonomously without requiring user knowledge of device identification information.
2Measurement precision
If knowledge of identification information is required for data transfer, then device identification accuracy is improved, but device complexity deteriorates
Solution Approach 1:
The patent uses visual copies of device identifiers presented as graphically encoded display elements. Instead of requiring users to input or recall complex identification information, the system captures visual representations (images) of these identifiers and processes them for automatic device recognition, simplifying the interaction while maintaining accuracy.
3Ease of operation
If automated image-based device identification is implemented, then ease of operation is improved, but measurement precision deteriorates
Solution Approach 1:
The patent introduces graphically encoded display elements as intermediary visual representations of device identifiers. These display elements serve as mediators between the physical device and the image processing system, encoding identification information in a visually distinct manner that facilitates accurate automated recognition while maintaining ease of operation.

AI summary
An example method includes presenting, on a first display screen associated with a first computing device, a first graphically encoded display element. The method also includes acquiring, using an image acquisition component associated with a second computing device, one or more images of the first display screen, determining that the one or more images correspond to the first display element, and responsive to determining that the one or more images correspond to the first display element, transferring a data item from the second computing device to the first computing device.
