Location-Based Audio Service for Mobile Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional augmented reality methods for mobile devices, which overlay information on the physical world, become physically and socially uncomfortable for users due to the need to continuously hold and view the device, especially during tasks like walking or driving.
Innovation Solution
A location-based audio service that delivers relevant information through an audio stream on mobile devices, using a Service Provider System to monitor geographic data and transmit personalized location-based information during inactive segments of audio playback, allowing users to receive information without needing to actively view the device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If augmented reality methods overlay information on the physical world through mobile devices, then users can access location-based information, but users experience physical discomfort and social awkwardness due to continuously holding and viewing the device
Solution Approach 1:
The patent replaces the mechanical visual interaction (holding and viewing device screen) with an acoustic interaction system. Audio transducers deliver location-based information through sound waves, allowing users to receive information without mechanical engagement with the device form factor, thus eliminating physical discomfort while maintaining information delivery
Solution Approach 2:
The patent introduces audio transducers as an intermediary medium between the mobile device and the user. Instead of direct visual contact with the device screen, information is transmitted through audio signals that can be perceived without holding or looking at the device, reducing social awkwardness and physical strain
2Loss of information
If location-based information is delivered continuously, then users receive comprehensive information, but users experience information overload and distraction from primary activities
Solution Approach 1:
The patent implements periodic action by delivering location-based information only during inactive segments of the audio stream. The system monitors activity levels and selectively activates information delivery during appropriate intervals, ensuring comprehensive information is provided when safe while maintaining safety during active periods
Solution Approach 2:
The patent employs feedback mechanisms by monitoring user activity state and dynamically adjusting information delivery. The system detects whether the user is engaged in primary activities and modulates information presentation accordingly, creating a closed-loop system that balances information completeness with safety
3Duration of action of moving object
If the audio stream is continuous without interruptions, then users enjoy seamless audio experience, but location-based information cannot be delivered
Solution Approach 1:
The patent applies segmentation by dividing the audio stream into active segments and inactive segments. Location-based information is delivered during inactive segments, allowing the audio experience to remain largely continuous while creating opportunities for information delivery without disrupting the overall flow

AI summary
Embodiments of the present invention provide a location-based audio service. According to one embodiment, a request for a desired audio stream having an inactive segment is received from a user operating a mobile device. Furthermore, geographic data may be monitored while the audio stream is being rendered on the mobile device. The location-based audio service is configured to determine relevant location-based information based on the geographic data, and then transmit the relevant information to the mobile device during the inactive segment of the desired audio stream.
