Audio AR Content Multiplexing for Distinguishable Sound Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional information provision systems face challenges in efficiently delivering multiple sounds without overlap, leading to indistinguishable audio experiences, as users often have to endure uninteresting sections while waiting for relevant information, and existing technologies fail to adapt playback based on user familiarity and proficiency.
Innovation Solution
An information provision system that selects and multiplexes content based on user position and familiarity, adjusting the multiplex level and sound numbers to ensure recognizable and efficiently provided audio, using a processor and memory to execute instructions for content selection, multiplexing, and sound localization, thereby optimizing audio AR environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple sounds are simply multiplexed and outputted, then the quantity of information provided increases, but the sounds become too overlapped and indistinguishable
Solution Approach 1:
The patent changes acoustic parameters including playback timing, playback speed, and sound pressure levels based on the number of multiplexed sounds. When multiple sounds are multiplexed, the system adjusts these parameters dynamically to maintain distinguishability while providing quantity of information.
Solution Approach 2:
The system dynamically adjusts playback characteristics based on real-time conditions including the number of multiplexed sounds, user position, and familiarity levels. This dynamic adaptation allows the system to optimize both information quantity and sound distinguishability according to current operational context.
2Productivity
If conventional information provision delivers sounds without considering user familiarity, then the system complexity is reduced, but the information provision efficiency decreases
Solution Approach 1:
The system incorporates feedback mechanisms by tracking user familiarity with specific sounds and locations. This feedback is used to adjust multiplexing strategies, providing more information when users are familiar with the content and reducing multiplexing when users are newcomers, thereby improving efficiency.
Solution Approach 2:
The system performs preliminary assessment of user familiarity and position before delivering multiplexed sounds. By pre-evaluating user characteristics, the system can optimize information delivery strategies in advance, improving provision efficiency without requiring complex real-time adjustments.
3Manufacturing precision
If the playback timings of sounds are adjusted to avoid overlap, then the distinguishability of sounds is improved, but the loss of time increases
Solution Approach 1:
The system uses periodic timing adjustments based on the number of multiplexed sounds, inserting appropriate time intervals between sound playbacks. When multiple sounds are multiplexed, periodic pauses are introduced to allow users to process information, balancing distinguishability with time efficiency.
4Adaptability or versatility
If position-based content selection is implemented, then the adaptability to user context is improved, but the device complexity increases
Solution Approach 1:
The system introduces position information as an intermediary parameter that mediates between user context and content selection. By using position data to determine which sounds to multiplex and at what levels, the system achieves context adaptability through a relatively simple mediation mechanism.

AI summary
An information provision device includes a processor; and a memory which stores a plurality of instructions, which when executed by the processor, cause the processor to execute, selecting a content corresponding to position information of a user from contents stored in a storage unit in advance; multiplexing the contents using a multiplex number that corresponds with familiarity of the user with the selected content; and providing the multiplexed contents to the user.
