AR Sound Localization via Virtual Object Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The presentation of information using sounds has been underexplored in Augmented Reality (AR) technology, where localization information of sounds related to virtual objects is not effectively generated based on their positions.
Innovation Solution
An information processing device and method that generates localization information for sound markers based on the virtual position of virtual objects, determined by the position of real objects in a space, allowing for the output of sounds associated with these markers, enhancing user experience by providing directional audio cues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If sound localization information is generated based on virtual object position in AR, then user awareness of surrounding information is improved, but the complexity of the information processing system increases
Solution Approach 1:
The patent combines visual marker position detection with sound localization information generation into a unified processing flow. The sound localization unit integrates with the visual processing chain, using the same virtual position data to generate both visual and auditory output, thereby reducing overall system complexity while improving information delivery
Solution Approach 2:
The patent introduces a sound localization information generation unit as an intermediary component that translates virtual object positions into directional sound cues. This mediator bridges the gap between visual AR elements and auditory feedback, enabling enhanced user awareness without requiring direct complex interactions between all system components
2Ease of operation
If directional sound output is provided based on face orientation, then user interaction with virtual objects is improved, but the device complexity increases
Solution Approach 1:
The face orientation detection unit serves multiple functions: it determines user attention direction for selecting virtual objects, provides spatial context for sound localization, and enables natural interaction without additional input devices. This multi-functionality reduces the need for separate interaction mechanisms, thereby improving ease of operation without proportionally increasing device complexity
Solution Approach 2:
The system uses the user's own face orientation as the interaction interface, eliminating the need for separate control devices or complex input mechanisms. The user's natural head movements directly control sound direction and object selection, making the system self-serve the interaction needs without adding external complexity
