Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing user authentication methods are inconvenient and vulnerable to attacks, and option selection mechanisms often require active physical input, which can be disruptive in public settings.
Innovation Solution
A system that uses EEG, EMG, and EOG signals to detect user attention on audibly presented options, allowing selection without physical motion, and performs user authentication based on brain activity responses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If password authentication is used, then cost is low, but convenience is poor and security is vulnerable to attacks
Solution Approach 1:
The patent replaces traditional mechanical/password-based authentication systems with a neurophysiological detection system that measures brain wave patterns (EEG), eye movement (EOG), and muscle activity (EMG) signals. This substitution eliminates the need for users to remember or input passwords, thereby improving both security (as these biological signals are difficult to replicate) and convenience (as authentication becomes automatic and contactless).
Solution Approach 2:
The system performs authentication automatically by continuously monitoring the user's neurophysiological signals without requiring active participation. The user simply needs to be present and attentive to the auditory options, and the system autonomously captures the brain's electrical responses and compares them against stored patterns to verify identity and determine selection intent.
2Ease of operation
If active physical input is required for option selection, then selection accuracy is high, but user convenience deteriorates in public settings
Solution Approach 1:
The patent replaces physical input mechanisms (such as button presses, voice commands, or gestures) with detection of the user's neurophysiological state. By measuring brain wave patterns associated with attention and cognitive processing, the system can infer which option the user intends to select without requiring any outward physical manifestation of their choice, thus maintaining accuracy while enabling discreet operation in public.
Solution Approach 2:
The system introduces an intermediary measurement layer between the user's internal intent and the system's action. Instead of directly observing physical inputs or relying on self-reporting, the system uses neurophysiological signals as an intermediary that indirectly but accurately reflects the user's cognitive state and selection intent, bridging the gap between internal thought and external system response.
3Reliability
If neurophysiological signals are used for authentication, then security and convenience are improved, but device complexity increases
Solution Approach 1:
The patent employs a multi-functional sensor system that simultaneously captures EEG, EOG, and EMG signals using integrated sensors positioned on or near the user's head. This universal sensing approach allows a single device configuration to perform multiple authentication and interaction functions, reducing the need for separate specialized hardware for each type of signal detection and thereby managing overall system complexity.
Solution Approach 2:
The system merges the detection and processing of multiple neurophysiological signal types (brain waves, eye movements, muscle activity) into a unified authentication and intent recognition framework. By combining these signals and processing them through a single comparative analysis system against stored user patterns, the patent reduces complexity compared to implementing separate independent systems for each signal type.

Data Source
AI summary
Described apparatus, systems, and methods for audibly presenting multiple options to a user and using user signals received from a user device worn by or otherwise coupled to the user, that are generated without any need for physical motion-based interaction from the user, to determine a presented option that is to be selected and performed on behalf of the user. In addition, the disclosed implementations may also be utilized to authenticate a user based on authentication signals received from the user device that are generated without any need for physical motion-based interaction from the user.
