Virtual Scene Sound Source Localization with Visual Map Markers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for determining the position of a sound source in a virtual scene are inaccurate, especially in noisy environments, as they rely solely on simulated sounds, which can be ambiguous and difficult to localize.
Innovation Solution
A method and apparatus that determine the position of a sound source by acquiring the position of a virtual role, detecting the sound source object within a detection area, calculating transparency of a position mark based on distance, and displaying the mark on an interaction interface to accurately indicate the sound source's location, independent of simulated sounds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If sound source position is determined only by simulated sound, then the system complexity is low, but the measurement precision deteriorates
Solution Approach 1:
The patent combines multiple determination methods (simulated sound positioning and visual mark positioning) into a unified system. The visual mark system merges map display with position indication, creating a composite positioning approach that overcomes the limitations of sound-only methods while maintaining reasonable system complexity.
Solution Approach 2:
The patent introduces visual marks as an intermediary element between the sound source and the user. Instead of relying directly on sound localization, the system uses visual markers on the map to indicate sound source positions, acting as a mediator that translates acoustic information into visual form for improved accuracy.
2Measurement precision
If visual position marks are added to indicate sound source, then the measurement precision improves, but the device complexity increases
Solution Approach 1:
The map display serves multiple functions: it shows the virtual scene layout, indicates player position, and displays sound source position marks. This multi-functionality reduces the need for separate dedicated components, improving measurement precision while controlling system complexity through efficient resource utilization.
Solution Approach 2:
The patent uses different visual characteristics (such as color or transparency variations) of position marks to convey different types of information about sound sources. This allows the system to encode multiple data dimensions in a single visual element, improving position indication accuracy without proportionally increasing system complexity.
3Speed
If sound detection area is limited, then the processing speed is high, but the measurement precision deteriorates
Solution Approach 1:
The system implements a layered detection approach where a primary sound detection area focuses processing on the most relevant region, while optional secondary detection areas provide extended coverage when needed. This partial action strategy maintains high processing speed for common cases while enabling improved precision when the situation requires broader detection.
Data Source
AI summary
This application discloses a method and apparatus for determining characteristics of a sound source. The method may include: acquiring a first position of a first virtual role in a virtual scene; detecting, in a sound source detection area associated with the first position, a second position of a sound source virtual object in the virtual scene; determining a position mark identifying the sound source virtual object; displaying a map, the first position in the virtual scene corresponding to a third position on the map; determining a fourth position on the map corresponding to the second position based on the first position and the third position, the fourth position relative to the third position on the map reflecting a direction of the second position relative to the first position in the virtual scene; displaying the position mark of the sound source virtual object at the fourth position on the map.
