Gaze-Based Comprehension Feedback for Text Objects
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Individuals often miss important information in text-based communications due to quick scanning, and existing solutions fail to reliably determine if key information has been grasped by the user, as they can be intrusive or lack feedback on comprehension.
Innovation Solution
An information handling device receives an indication to open a text object, identifies key information through context analysis, uses a camera sensor to ascertain user gaze, and provides a visual indication of the user's comprehension of that information, determining the degree to which the user is apprised of the key information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If users quickly scan text-based communications to save time, then reading speed is improved, but comprehension reliability deteriorates
Solution Approach 1:
The system provides visual feedback through gaze indication overlays that show users where they are looking relative to key information regions. This feedback loop allows users to adjust their reading behavior in real-time to ensure they are viewing the important portions of the text, thereby maintaining comprehension reliability while preserving quick scanning habits.
Solution Approach 2:
The system performs preliminary identification and highlighting of key information regions before the user completes their reading. By pre-marking the important areas that require attention, the system guides users to focus on comprehension-critical content during their quick scan, ensuring that even rapid reading captures the essential information.
2Reliability
If the system provides continuous feedback to improve comprehension, then comprehension reliability is improved, but user experience intrusiveness worsens
Solution Approach 1:
The feedback mechanism applies local quality by providing gaze indication overlays only in specific key information regions rather than throughout the entire text. This localized approach delivers comprehension feedback precisely where it is needed most, while leaving the rest of the reading experience undisturbed and non-intrusive.
Solution Approach 2:
The system implements partial action by providing feedback only for identified key information regions rather than monitoring or feedback for the entire text. This selective feedback approach maintains comprehension reliability for critical content while minimizing overall intrusiveness in the user experience.
3Measurement precision
If the system monitors user gaze to assess comprehension, then comprehension measurement precision is improved, but device complexity worsens
Solution Approach 1:
The camera sensor serves as an intermediary device that captures visual information about user gaze without requiring direct integration with the display or text processing systems. This intermediary approach enables comprehension monitoring through a separate, dedicated component that simplifies the overall system architecture while maintaining measurement precision.

AI summary
One embodiment provides a method, including: receiving, at an information handling device, an indication to open a text object; identifying, based upon analysis of context data associated with the text object, at least one article of key information contained within the text object; ascertaining, using a camera sensor, an aspect of user gaze within the text object; determining, based on the identified at least one article of key information and the ascertained aspect of user gaze, a degree to which a user is apprised of the at least one article of key information contained within the text object; and providing, based on the determining, a visual indication of the degree to which the user is apprised of the at least one article of key information. Other aspects are described and claimed.
