Assistive Technology Cognitive State Guidance Injection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Assistive technologies, such as screen readers, struggle to provide relevant user experiences in real-time to users with disabilities or specialized needs, as existing solutions require keyboard input to access alerts or events, disrupting the current context and failing to seamlessly integrate user feedback and guidance.
Innovation Solution
A method that determines a user's cognitive state through interaction with a computer system, searches for relevant user experiences from social networks or databases, and injects selected experiences into the user's context via output devices, such as screen readers, to provide timely assistance and guidance without distracting the user.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If keyboard input is used to access alert or event content, then information can be retrieved, but the user's current context is disrupted and task flow is interrupted
Solution Approach 1:
The system segments information delivery by injecting only relevant user experiences and guidance into the current context, rather than requiring users to access complete alert content through keyboard navigation. This selective information segmentation maintains task flow while providing necessary support.
Solution Approach 2:
The system merges the alert information delivery with the user's current task context by injecting experiences directly into the active workflow. This integration allows information access without context disruption, as the guidance is embedded within the ongoing task rather than requiring separate access actions.
2Productivity
If user experiences are provided in real-time, then task performance is improved, but system complexity increases
Solution Approach 1:
User experiences are pre-collected and stored in a database before being needed. When a user encounters a situation, the system queries and retrieves relevant pre-prepared experiences, enabling real-time support without the complexity of generating or processing experiences on-the-fly.
Solution Approach 2:
A database serves as an intermediary layer between users and the complex task of curating user experiences. The database stores, organizes, and manages experience data, allowing the assistive technology to provide real-time support without directly handling the complexity of experience collection, validation, and management.
3Ease of operation
If guidance is injected into current context, then user frustration is reduced, but information relevance becomes harder to ensure
Solution Approach 1:
The system uses feedback mechanisms to monitor user cognitive state and task progress, continuously adjusting which user experiences are injected into the current context. This feedback loop ensures that only relevant information is provided, maintaining both low frustration levels and high information relevance through adaptive selection based on actual user needs.

AI summary
A method of providing guidance in connection with a technological task includes determining, from an interaction of an end user with a computer system, a current context and task of the end user, identifying a change in a cognitive state of the end user, where the change in the cognitive state is associated with performance of the task using the computer system, searching a plurality of user experiences corresponding to the change in the cognitive state of the end user and the user's current context, selecting at least one of the user experiences according to a selection parameter for determining a selected user experience, and injecting the selected user experience into the current context of the end user via an output device of the computer system.
