Surgical Voice Control System Error Feedback Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional endoscopic surgical systems are not user-friendly for performing therapeutic procedures due to the requirement for hierarchical and intentional voice commands to operate medical instruments, making them difficult to use effectively.
Innovation Solution
A surgical system controlling method and apparatus that includes a voice information inputting step, voice recognition processing, guidance data storage, and guidance voice generation, allowing for hierarchical recognition and feedback on operation state voice information, with error guidance provided when recognition rates fall below predetermined thresholds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If hierarchical and intentional voice commands are used to operate medical instruments, then the system can control multiple instruments, but the system becomes difficult to use and not user-friendly
Solution Approach 1:
The system provides real-time feedback to the user by announcing recognized voice commands and their corresponding operations. This feedback mechanism allows users to confirm that their voice input was correctly interpreted, reducing anxiety about misrecognition and making the system feel more responsive and user-friendly while maintaining full voice control automation
Solution Approach 2:
The voice recognition system acts as an intermediary between the user and the complex instrument control system. It translates natural language voice commands into structured control signals, shielding users from the complexity of hierarchical command structures while maintaining precise control over multiple medical instruments
2Ease of operation
If voice recognition is used to control surgical instruments, then operatability is improved, but misrecognition may occur leading to operational errors
Solution Approach 1:
The system announces each recognized voice command before execution, providing users with an opportunity to verify correctness. If a command is misrecognized or not recognized, the system can prompt the user to repeat or clarify, preventing erroneous operations while maintaining ease of use
Solution Approach 2:
The system takes preliminary action by validating and confirming voice commands before execution. This preventive approach counteracts potential misrecognition errors by checking recognition confidence levels and requiring user confirmation for critical operations, ensuring reliability without compromising operatability

AI summary
In this invention, a voice recognition engine 110 outputs to a controlling section 103 a matching state of a voice input signal as an error code. Then, the controlling section 103 determines the matching state based on the error code in the error determination section 105 and outputs to a voice synthesizing engine 113 guidance data according to the matching state based on a timing control by a guidance timing controlling section 107. According to such a configuration, this invention improves operatability by voice operation, while reducing a risk of erroneous recognition by maintaining a predetermined matching rate.
