Dynamic Sound Localization for Moving Objects
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing techniques for localizing sound images on objects, particularly moving objects, fail to accurately output desired sound data as the position of the object changes, leading to incorrect sound emission points.
Innovation Solution
An information processing apparatus and method that acquires user and object position information to generate sound information localized on the object, ensuring accurate sound output even when the object moves, using units for position acquisition, sound generation, and control for real-time sound output.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If sound data is processed based only on user information assuming fixed object position, then processing complexity is reduced, but sound localization accuracy deteriorates when the object moves
Solution Approach 1:
The system transitions from a static object position assumption to a dynamic tracking approach. The information processing apparatus continuously acquires updated position information of the object and recalculates sound data accordingly, making the sound localization adaptive to object movement rather than relying on fixed position assumptions
Solution Approach 2:
The system implements a feedback mechanism where the object's position information is continuously monitored and fed back into the sound data processing pipeline. This closed-loop approach ensures that sound localization remains accurate by constantly adjusting based on the current object position rather than relying on initial position data
2Measurement precision
If the system tracks object position to maintain sound localization accuracy, then sound localization accuracy is improved, but system complexity increases
Solution Approach 1:
The information processing apparatus performs multiple functions using a unified processing framework. It simultaneously acquires user position information, object position information, calculates relative positions, and generates sound data within a single integrated system, avoiding the need for separate specialized modules for each function
Solution Approach 2:
The system manages complexity by dynamically adjusting processing parameters based on object movement. Instead of continuously processing at full complexity, it modifies processing intensity and frequency according to whether the object is stationary or moving, optimizing the balance between accuracy and system resource consumption

AI summary
Provided is an information processing apparatus capable of outputting a desired sound to a user. An information processing apparatus includes: a first acquisition unit that acquires first position information indicating position information of a user; a second acquisition unit that acquires second position information indicating position information of a predetermined object; a generation unit that generates, based on the first position information and the second position information, sound information in which a sound image is localized on the predetermined object, the sound information being related to the predetermined object; and a control unit that executes control to output the generated sound information to the user.
