Transmissive Display Visual Overlay Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable music players do not enable users to traverse the real world while listening to music and simultaneously experience visually modified surroundings that are time-synchronized with the audio, lacking the ability to enhance the music listening experience by overlaying visual content that changes in synchrony with the music.
Innovation Solution
A portable music playing apparatus with a processor, transmissive display, and audio processing subsystem that generates and displays music-responsive visual overlays, allowing users to view the real world with overlaid content that varies in brightness, color-tinting, or shape in synchronization with the audio output, without requiring spatial registration with the real world.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If spatial registration and tracking systems are implemented to provide accurate visual overlays, then the precision of visual synchronization is improved, but the device complexity and cost increase significantly
Solution Approach 1:
The patent extracts and removes the complex spatial registration and tracking systems from the augmented reality device. Instead of requiring precise tracking of user position and orientation, the invention uses simple visual overlays that do not depend on accurate spatial alignment, thereby reducing device complexity while maintaining visual synchronization through alternative means.
Solution Approach 2:
The patent inverts the traditional approach by not trying to make the visual content accurately match the real-world spatial coordinates. Instead, it overlays visual content that is intentionally decoupled from precise spatial registration, allowing the visual elements to be displayed without complex tracking infrastructure.
2Adaptability or versatility
If transmissive display is used to overlay visual content, then the user can view the real world simultaneously, but the visual content brightness and visibility may be reduced
Solution Approach 1:
The patent employs parameter changes by dynamically adjusting the optical properties of the transmissive display, such as modulation depth, transparency levels, and brightness compensation, to optimize both real-world visibility and visual content prominence under varying lighting conditions.
Solution Approach 2:
The system uses dynamic control of display parameters based on ambient light sensing and user interaction, allowing the visual content brightness to be adjusted in real-time to maintain visibility while preserving the transmissive nature of the display for real-world viewing.

AI summary
A portable music player apparatus that outputs visual content to a head-worn transmissive display, the visual content being modulated in time with playing musical content and overlaid upon the user's direct view of his or her physical surroundings. In this way, the user is provided with an enhanced visual view of his or her physical surroundings, the enhanced visual view including transmissive visual content that is generally synchronized in time with the playing music content. This provides the user with an improved music listening experience in which he or she feels present within a visually enhanced version of the physical world that has changing visual qualities that are perceptually synchronized in time with one or more features of the playing music. The displayed visual content may include time-varying translucency and/or color-tinting such that the user's direct view of the physical world changes in brightness and/or color tinting in a manner choreographed with the playing music.
