Eye-Tracked Visual Display Timing for Audio-Synced Reading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies struggle to provide an efficient and synchronized presentation of both visual and audio content, particularly in electronic reading devices, leading to suboptimal user interaction and engagement.
Innovation Solution
A selective visual display system that integrates eye-tracking technology to synchronize the presentation of digital content with audio, using a processor to control the timing and sequencing of content elements, ensuring that visual content is displayed and removed in harmony with the corresponding audio segments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If visual content is displayed continuously on the screen, then users can see the content, but user engagement and comprehension decrease due to lack of synchronization with audio
Solution Approach 1:
The patent segments the continuous visual content into discrete content elements that are individually synchronized with audio segments. Each content element is displayed only during its corresponding audio segment, creating a segmented presentation that improves synchronization accuracy and user engagement.
2Loss of information
If multiple content elements are displayed simultaneously, then information is available, but user focus and comprehension are reduced
Solution Approach 1:
The patent implements periodic display of content elements, where each content element appears during its specific audio segment and is removed when the segment ends. This periodic action ensures complete information availability while maintaining user focus on one element at a time, thereby improving reading efficiency.
3Adaptability or versatility
If visual and audio content are presented without coordination, then presentation flexibility is maintained, but user engagement and comprehension suffer
Solution Approach 1:
The patent employs a content sequencing logic that monitors audio segment playback and provides feedback to control the display timing of content elements. This feedback mechanism ensures that content elements are displayed only when their corresponding audio segments are playing, maintaining both synchronization accuracy and presentation flexibility.
