Brain-Information Command Verification for Accurate Operation Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional brain-machine interfaces (BMIs) are prone to issuing unintended commands due to irrelevant stimuli, such as verbal cues or visual feedback, leading to inaccurate operation control.
Innovation Solution
An operation control device that includes a brain information acquiring unit, a determining unit to differentiate between first and second commands, an information presenting unit to evoke the second command, and an executing unit to execute the first command only after confirming the second command is acquired, thereby preventing unintended operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional BMI acquires brain information and executes commands based on brain wave patterns, then operation control is achieved, but irrelevant stimuli cause unintended commands to be issued
Solution Approach 1:
The system performs preliminary action by acquiring and storing brain information corresponding to the second command before executing the first command. This preliminary acquisition creates a verification mechanism that prevents unintended operations caused by irrelevant stimuli, as the system checks for the presence of the second command's brain pattern before final execution.
Solution Approach 2:
The patent introduces an intermediary verification step between brain information acquisition and command execution. The determining unit acts as a mediator that compares acquired brain information against stored patterns for both first and second commands, ensuring that execution only occurs when the correct command pattern is identified, thus filtering out false positives from irrelevant stimuli.
2Speed
If the system executes commands immediately upon detecting brain wave patterns, then response speed is improved, but false commands from irrelevant stimuli are executed
Solution Approach 1:
The system performs preliminary acquisition and storage of brain information for the second command before execution is needed. This pre-prepared verification pattern enables rapid comparison and decision-making during actual operation, maintaining high response speed while ensuring accuracy through the pre-established comparison mechanism.
3Reliability
If the system monitors for both first and second commands continuously, then command accuracy is improved, but system complexity increases
Solution Approach 1:
The patent uses copying by storing brain information patterns for the second command in advance. Instead of developing complex real-time analysis algorithms, the system creates copies of expected brain patterns and compares incoming signals against these stored copies, simplifying the system structure while maintaining high command accuracy through pattern matching.

AI summary
An operation control device includes: a brain information acquiring unit configured to acquire brain information of a user; a determining unit configured to determine whether or not the brain information acquired by the brain information acquiring unit represents brain information corresponding to a first command and a second command which are different from each other; an information presenting unit configured to present information which evokes the second command to the user; and an executing unit configured to execute operation specified in the first command when the determining unit determines that the brain information corresponding to the second command is acquired after acquiring the brain information corresponding to the first command.
