Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional help information for software and devices is not personalized to individual users' understanding levels, failing to adapt to changes in user comprehension over time.
Innovation Solution
A method utilizing EEG data from brain-computer interfaces to customize help information by selecting cognitive states and emotional states of users, tailoring the organization, detail, complexity, and content of help information based on their brain activity and gaze tracking data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional help information is provided to all users, then the help information is simple and easy to maintain, but it fails to adapt to individual users' understanding levels and cognitive states
Solution Approach 1:
The help information system dynamically adapts its content, organization, detail level, and complexity based on real-time EEG-detected cognitive states and emotional states of users. The system transitions from static, one-size-fits-all help information to a dynamic, personalized delivery mechanism that adjusts automatically according to user brain activity patterns.
Solution Approach 2:
The system changes multiple parameters of help information including organization structure, detail level, complexity, and content selection based on detected cognitive and emotional state parameters. Different cognitive states trigger different help information configurations, allowing the same system to present vastly different help content to different users or to the same user at different times.
2Ease of operation
If help information is customized based on EEG data and cognitive states, then personalization and effectiveness are improved, but the system complexity and data processing requirements increase
Solution Approach 1:
The system automatically detects user cognitive states through EEG data and autonomously selects and delivers appropriate help information without requiring user input about their understanding level. The system serves itself by interpreting brain activity patterns and automatically adjusting help delivery, eliminating the need for users to manually configure help preferences.
Solution Approach 2:
The system continuously monitors user cognitive states through EEG feedback and uses this information to adjust help information delivery in real-time. This closed-loop feedback mechanism ensures that help information is continuously optimized based on actual user comprehension and cognitive load, creating an adaptive learning system.
3Adaptability or versatility
If real-time EEG monitoring is implemented to detect cognitive states, then help information can be dynamically adapted, but the hardware requirements and data processing load increase
Solution Approach 1:
The system processes and analyzes only the most relevant portions of EEG data corresponding to specific cognitive states and help information delivery moments, rather than continuously processing all EEG signals. This selective processing approach reduces computational load and energy consumption while maintaining effective real-time adaptation capability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Provides personalized help information that better matches the user's understanding and emotional state, enhancing the effectiveness of using software and devices by automatically adjusting content to meet individual needs.
Implementation Method 1
Electroencephalography (EEG) is the measurement of electrical activity in a person's brain as measured on a person's scalp. The electrical activity is derived from ionic current flow within the brain's neurons
Data Source
AI summary
A method implemented by a computing device for helping a particular user use a user interface (UI). Electroencephalography (EEG) data is obtained that indicates brain activity of a particular user during a period in which that user views the UI and/or interprets help information that describes how to use the UI. Based on the EEG data, the computing device selects, from among multiple predefined cognitive states, the one or more cognitive states that characterize the particular user during the period. The computing device assists the particular user to use the UI by customizing the help information for the particular user based on the one or more selected cognitive states. A complementary computing device and computer program product are also disclosed.
