Adaptive Soundtrack System for Reading Speed Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing soundtracks for text sources, such as books, lack synchronization with the reading pace, failing to enhance the reading experience as they do not adjust audio features like start and stop times based on the reader's speed, leading to suboptimal engagement.
Innovation Solution
A composite soundtrack system with multiple layers of audio features that can adjust start and stop times based on the reader's input speed, ensuring synchronized playback with text chunks, allowing for customizable audio properties like fade-in, fade-out, and transition effects to maintain seamless listening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If soundtracks use fixed preset start times for audio features, then the soundtrack structure is simple and easy to produce, but the synchronization with reader's pace is poor
Solution Approach 1:
The patent implements dynamic timing adjustment by allowing the playback system to modify preset start times of audio features based on detected reading speed. The system transitions from static fixed timing to dynamic adaptive timing, where audio features are triggered at optimized moments that match the reader's pace, resolving the contradiction between synchronization precision and structural complexity
Solution Approach 2:
The system changes the temporal parameters of audio features by adjusting start times and durations based on reading speed measurements. By varying these parameters dynamically, the soundtrack achieves precise synchronization with the reader's pace while maintaining a manageable structure through parameter-based control
2Adaptability or versatility
If soundtracks adjust audio feature timing to match reading speed, then the reading experience is enhanced, but the soundtrack becomes more complex and harder to produce
Solution Approach 1:
The patent applies preliminary action by pre-calculating and storing multiple timing configurations for audio features corresponding to different reading speeds. During playback, the system selects and applies the appropriate pre-prepared timing set, enabling reading speed adaptability without requiring complex real-time calculations, thus easing the production process
Solution Approach 2:
The system manages complexity by organizing timing parameters into structured configurations that can be selectively applied. By parameterizing the timing data and using systematic parameter changes based on detected reading speed, the system achieves adaptability while maintaining production efficiency through reusable parameter sets
3Adaptability or versatility
If multiple sound layers with concurrent audio features are used, then the soundtrack provides richer auditory experience, but the synchronization difficulty increases
Solution Approach 1:
The patent segments the multi-layer soundtrack into independent audio feature units, each with its own preset timing parameters. By dividing the complex multi-layer structure into manageable segments that can be individually timed and triggered, the system achieves precise synchronization across layers while maintaining the richness of the auditory experience
Solution Approach 2:
The system uses an intermediary timing control mechanism that coordinates all sound layers through a unified timing framework. This intermediary layer manages the concurrent audio features by referencing the reader's pace and triggering features across different layers at synchronized moments, resolving the synchronization difficulty while preserving audio layer complexity
Data Source
AI summary
A composite variable duration soundtrack for a user to play while reading a text source, the soundtrack duration being defined by a soundtrack timeline. The soundtrack comprises multiple sound layers configured to play concurrently through the soundtrack timeline, each sound layer having an arrangement of one or more audio features that are configured to play at preset start times in the soundtrack timeline. At least one sound layer is adapted for modifying the preset start and stop times of its audio features to match the reading speed of a user based on a reading speed input.
