Voice-Activated Medical Query System with Confirmation Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users often lack access to comprehensive information about medications and medical devices, as Patient Information Leaflets (PILs) may not be fully read or understood, leading to potential misuse or unanswered questions, and existing systems do not effectively provide tailored responses to user queries.
Innovation Solution
A method and apparatus that utilize voice recognition to convert audio signals into natural language queries, connect to a medical database for responses, and provide audio or video outputs, with the option to transmit queries to a secondary answering facility for unanswered questions, ensuring secure user identity verification and logging of interactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If voice recognition is used to enable hands-free querying, then ease of operation is improved, but reliability may deteriorate due to potential misinterpretation of voice commands
Solution Approach 1:
The system displays the interpreted query back to the user and requests confirmation before executing. This feedback loop allows users to verify that their voice command was correctly interpreted, enabling easy hands-free operation while maintaining reliability through user verification.
2Loss of information
If a comprehensive medical database is implemented, then information completeness is improved, but device complexity increases
Solution Approach 1:
The patent uses an intermediary processing layer that includes natural language interpretation, query generation, and database interaction management. This intermediary handles the complexity of database queries and data retrieval, allowing the system to access comprehensive medical information without exposing the full complexity to the user interface.
3Reliability
If user identity verification is implemented, then security is improved, but ease of operation deteriorates due to additional verification steps
Solution Approach 1:
The system performs voice-based user identification automatically without requiring manual authentication steps. The user simply speaks their query, and the system identifies them through voice recognition, providing secure access while maintaining ease of operation through automated self-service identification.
Data Source
AI summary
The application relates to providing medical information in response to a query, in particular, although not exclusively, to a method of querying a medical database using voice recognition. According to an embodiment, there is provided a medical query answering apparatus that is configured to convert detected audio signals into a natural language data stream; determine from the natural language data stream whether a voice command for information relating to a medical device or a medicament has been issued by a user; in response to a positive determination, convert at least part of the natural language data stream into a query for querying a medical database; supply the query to the medical database and receive a response therefrom; and provide an audio output based at least in part on the response from the medical database.
