Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems fail to effectively assess and respond to a user's attentive state during content consumption, leading to suboptimal user experiences, particularly in extended reality environments.
Innovation Solution
A device that utilizes eye-tracking technology to monitor gaze characteristics, determining a user's attentive state through variability analysis, and provides feedback or adjusts content accordingly to maintain the intended state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If eye-tracking technology is used to monitor gaze characteristics, then user attentive state can be determined, but device complexity increases
Solution Approach 1:
The patent uses gaze characteristics as an intermediary indicator to infer the user's attentive state. Instead of directly measuring cognitive state through complex brain imaging, the system tracks eye movement patterns (gaze direction, fixation duration, saccade frequency) which serve as observable proxies for attentional processes, thereby achieving accurate assessment without requiring complex direct neural measurement equipment
Solution Approach 2:
The system replaces complex mechanical or biological measurement systems with optical sensing and computational analysis. By substituting direct neural monitoring with eye-tracking cameras and algorithmic analysis of gaze patterns, the system achieves attentive state detection with simpler hardware requirements and lower system complexity
2Productivity
If real-time feedback is provided based on gaze patterns, then user engagement is enhanced, but measurement precision requirements increase
Solution Approach 1:
The system provides feedback based on aggregated gaze pattern analysis rather than requiring perfect measurement precision for every individual gaze point. By analyzing cumulative metrics such as total fixation duration, saccade count, and overall gaze trajectory patterns over time windows, the system achieves sufficient accuracy for effective feedback without demanding extreme measurement precision at every moment
Solution Approach 2:
The patent implements a feedback loop where gaze data is continuously collected, analyzed, and used to provide real-time feedback to the user. This feedback mechanism (such as visual cues, audio prompts, or haptic signals) guides the user to maintain desired attentional states, thereby enhancing engagement while allowing for reasonable measurement tolerances through adaptive feedback adjustment

AI summary
Various implementations disclosed herein include devices, systems, and methods that determine an attentive state of a user during an experience (e.g., visual and/or auditory content that could include real-world physical environment, virtual content, or a combination of each) based on the user's gaze characteristic(s) to enhance the experience. For example, an example process may include obtaining physiological data associated with a gaze of a user during an experience, determine a gaze characteristic during a segment of the experience based on the obtained physiological data, and determine that the user has a first attentive state during the segment of the experience based on classifying the gaze characteristic of the user during the segment of the experience.
