Voice-Guided Slide Selection Using Keyword Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing presentation systems fail to accurately match voice-recognized terms with appropriate slide content, leading to inappropriate slide reading during presentations.
Innovation Solution
A display device that extracts conversation-derived terms, converts them into search keywords, and uses these keywords to identify relevant presentation material pages, displaying selection terms for slide navigation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If voice recognition is used to identify slides, then hands-free operation is improved, but slide selection accuracy deteriorates because recognized terms do not necessarily match search terms associated with slides
Solution Approach 1:
The patent introduces an intermediary mechanism that maps voice-recognized terms to search keywords through a database of term associations. When a user speaks a term, the system retrieves associated search keywords from the database, which then accurately match with slide content, resolving the mismatch between spoken terms and slide search terms.
Solution Approach 2:
The system performs preliminary action by pre-establishing associations between terms and search keywords in a database before the actual slide selection occurs. This pre-processing enables accurate matching when voice recognition captures terms, as the relationships are already prepared and stored.
2Device complexity
If only recognized terms are used for slide search, then processing simplicity is improved, but slide reading appropriateness deteriorates due to term-mismatch
Solution Approach 1:
The patent introduces an intermediary layer (the database of term associations) between the simple voice recognition output and the slide search process. This intermediary expands the simple recognized terms into multiple associated search keywords, enabling reliable slide matching without significantly complicating the overall processing architecture.
