Adaptive Content Speed for Wearable AR
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Augmented and virtual reality systems fail to adapt content presentation speed effectively to user motion and interest, leading to inconsistent and often unnatural delivery of audio and visual content, particularly when users move at varying paces or show differing levels of engagement.
Innovation Solution
Implementing a system that adjusts the presentation speed of content items based on user motion and gaze direction, using wearable devices with motion sensors and eye tracking, to synchronize content delivery with user movement and attention, applying pitch normalization for intelligible audio and capping presentation speed to maintain engagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If content presentation speed is kept constant regardless of user motion, then content delivery is simple and consistent, but the content delivery becomes unnatural and fails to adapt to user behavior
Solution Approach 1:
The patent implements dynamic adjustment of content presentation speed based on real-time user motion data. The system continuously monitors user velocity through motion sensors and adapts the playback speed of audio and video content accordingly, transitioning from a static to a dynamic presentation model that responds to user behavior.
Solution Approach 2:
The system employs feedback mechanisms by continuously tracking user motion and using this information to adjust content presentation parameters. Motion sensors provide real-time data about user movement, which feeds back to the content delivery system to modify playback speed, creating a closed-loop adaptive presentation system.
2Speed
If content presentation speed is increased to match fast user movement, then content delivery keeps pace with user motion, but content intelligibility may be compromised
Solution Approach 1:
The patent applies parameter changes by adjusting the playback speed parameter of content based on user motion velocity. When users move quickly, the system increases presentation speed to maintain synchronization with user movement through the environment, while still preserving content intelligibility through controlled parameter adjustment.
3Adaptability or versatility
If motion sensors and eye tracking are integrated to detect user behavior, then content presentation can be highly personalized, but device complexity and processing requirements increase
Solution Approach 1:
The patent implements multi-functionality by using motion sensors that serve multiple purposes: tracking user position, determining movement velocity, and inferring user engagement level. This universal sensor system replaces what would otherwise require separate specialized sensors for each function, reducing overall device complexity while maintaining personalization capabilities.

AI summary
Systems and methods are disclosed for adaptation of presentation speed for content presentation (e.g., audio content presentation). For example, methods may include obtaining an indication of motion within a space; adjusting a presentation speed based on the indication of motion; and presenting a content item associated with a location in the space, wherein the content item is presented using the adjusted presentation speed.
