Gaze Tracking Filtering for HMD Reading Control Mode
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of head-mounted displays (HMDs) face challenges when reading or concentrating on fine details due to the three-dimensional environment, which can cause eye unfocusing and difficulty in manipulating small objects.
Innovation Solution
A gaze tracking system that filters gaze tracking information to detect reading patterns, triggering a 'reading control mode' that initiates commands based on the user's gaze dwell time on specific words or objects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If three-dimensional environment is used in HMDs, then immersive experience is improved, but reading and concentration on fine details becomes difficult
Solution Approach 1:
The system dynamically switches between different operational modes (standard 3D mode and reading mode) based on detected gaze patterns. When reading behavior is detected through gaze tracking analysis, the system transitions to a specialized reading mode that optimizes the display for text and fine details, thereby adapting the three-dimensional environment to support both immersion and reading tasks effectively
2Measurement precision
If gaze tracking is continuously monitored, then reading pattern detection accuracy is improved, but computational load increases
Solution Approach 1:
The system applies partial monitoring by continuously tracking gaze position but only performing full pattern analysis when specific conditions are met (e.g., sustained fixation duration, specific gaze trajectories). This selective analysis approach maintains high detection accuracy for reading patterns while reducing unnecessary computational processing during normal navigation or non-reading activities
Solution Approach 2:
The system performs preliminary filtering of gaze data by detecting basic fixation events and saccade patterns before committing to full reading pattern recognition. This preliminary analysis stage processes only essential features of gaze behavior, reducing the computational burden of subsequent pattern classification while maintaining accurate reading detection

AI summary
A method, and system for controlling a computer program are disclosed. One or more images are presented on a display device in response to execution of the computer program on a computing device. Gaze tracking information corresponding to a location of a user's gaze with respect to the one or more images presented on the display device is collected over time. The gaze tracking information over time is analyzed to detect a pattern of the user's gaze characteristic of reading and upon detecting the pattern of the user's gaze characteristics of reading, a reading control mode is activated. In the reading control mode location and duration of the user's gaze triggers commands affecting execution of the computer program.
