Object Recognition System for Visually Impaired Users
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current solutions for the visually impaired are limited in their applicability due to their fragmented nature, making it difficult for individuals to interact with their surroundings effectively, as they often rely on narrowly tailored assistance that does not provide comprehensive object recognition and presentation.
Innovation Solution
A system comprising a camera, audio output device, audio input device, visual prosthesis, and processing circuitry that captures images, compares characteristic features to an object identification dataset, identifies objects, determines their names, and provides feedback to the user, allowing for the selection and localization of objects within the field of view through audio and visual cues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate solutions are used to assist the visually impaired, then specific tasks can be performed, but the overall system complexity increases and usability decreases
Solution Approach 1:
The patent combines camera-based object recognition, audio output for object identification, visual prosthesis for enhanced imaging, and tracking functionality into a single integrated system. This merging eliminates the need for multiple separate devices, reducing overall system complexity while maintaining comprehensive assistive capabilities for the visually impaired.
Solution Approach 2:
The integrated system performs multiple functions including object recognition, object tracking, audio annotation, and visual enhancement through a single device. This multi-functionality increases adaptability and versatility, allowing the system to assist with various tasks such as identifying objects, locating them in the field of view, and providing both auditory and visual feedback mechanisms.
2Ease of operation
If comprehensive object recognition is implemented, then interaction with the environment improves, but processing requirements and system complexity increase
Solution Approach 1:
The system segments the complex task of environmental interaction into distinct functional modules: camera capture, object recognition processing, audio output generation, visual prosthesis rendering, and tracking algorithms. This segmentation allows each component to be optimized independently while working together as an integrated system, managing processing complexity through modular architecture.
3Productivity
If real-time object tracking and identification is provided, then mobility and interaction improve, but energy consumption increases
Solution Approach 1:
The system employs periodic action by implementing event-triggered updates rather than continuous processing. The visual prosthesis and audio output are updated based on detected changes in object positions or new object identifications, rather than continuously. This periodic update mechanism maintains real-time functionality for mobility and interaction while significantly reducing overall energy consumption compared to continuous processing.
