Device Linking via Appearance Recognition and Server Mediation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In augmented reality applications, recognizing objects without pre-recorded marker images is challenging, especially for unknown or dynamically changing applications, as they lack distinct features for recognition.
Innovation Solution
An information processing apparatus that acquires and sends appearance information, including image and communication details, to link devices by recognizing the device's appearance, allowing for real-time identification and communication without pre-recorded dictionary data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If marker images or pre-recorded dictionary data are used for object recognition, then recognition accuracy is improved, but the system cannot recognize unknown or dynamically changing applications
Solution Approach 1:
The system performs preliminary actions by having the target device send its appearance information (screen capture, device specifications, application list) in advance to the server. This allows the recognizing device to retrieve and compare this pre-prepared information with captured images, enabling recognition without requiring pre-recorded marker images or dictionary data for each specific application
Solution Approach 2:
A server acts as an intermediary between the recognizing device and the target device. The server stores appearance information sent from target devices and provides it to recognizing devices for comparison. This intermediary mechanism enables indirect recognition without requiring direct pre-recording of features for each application, thus handling unknown and dynamically changing applications
2Ease of operation
If marker images are added to objects for recognition, then object recognition is enabled, but the method becomes complicated and requires additional tagging
Solution Approach 1:
The invention extracts and uses the device's own appearance information (screen display, specifications, application list) as the recognition target, eliminating the need for external marker images. The system captures and compares the natural appearance of the device and its displayed content, removing the complexity of adding special tags while maintaining recognition capability
Solution Approach 2:
The target device serves itself by automatically sending its appearance information to the server. The device's own screen display and specifications become the recognition features, eliminating the need for external markers or tags. This self-service approach simplifies the system by using the device's inherent characteristics for recognition
3Productivity
If pre-recorded dictionary data is stored for recognition, then recognition speed is improved, but unknown applications cannot be recognized
Solution Approach 1:
The system dynamically updates appearance information on the server as devices and applications change. Instead of using static pre-recorded dictionary data, the server stores current appearance information that can be updated in real-time. This dynamic approach maintains fast recognition speed through efficient database queries while adapting to new and changing applications automatically
