Spatial Audio Localization for Wide-Area Attention Sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems struggle to effectively share the attention of users in a wide area due to differing view directions, making it difficult to transmit attention from one user to others.
Innovation Solution
An information processing device that controls the spatial localization of audio for users based on their view directions, allowing for synchronization of audio coordinates with captured images, thereby facilitating attention sharing among users.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a wide area image is distributed in real time for multi-user viewing, then users can view the same scene from remote locations, but it becomes difficult to transmit attention of a certain person to others due to different view directions
Solution Approach 1:
The patent introduces an audio signal as an intermediary to convey attention information between users. When one user views a particular area, their audio is spatially localized to correspond to that area, serving as a mediator that transmits attention information to other users without requiring them to physically share the same viewpoint.
Solution Approach 2:
The patent adds the audio dimension to the visual wide area image system. By incorporating spatially localized audio signals that correspond to specific areas in the wide area image, the system creates a multi-dimensional attention transmission mechanism that overcomes the limitation of two-dimensional visual-only communication.
2Loss of information
If spatial localization of audio is controlled based on view direction information, then attention sharing among users is improved, but system complexity increases due to coordinate synchronization requirements
Solution Approach 1:
The patent merges the audio coordinate system with the wide area image coordinate system based on view direction information. By synchronizing these coordinate systems and controlling audio spatial localization according to the user's viewing direction, the system integrates multiple information streams into a unified attention transmission mechanism.

AI summary
There is provided an information processing device, an information processing method, and a recording medium that enable sharing of attention of users existing in a wide area. The information processing device includes a control unit that performs control of spatial localization of an audio of another user except a target user on the basis of information regarding at least one of a view direction of a first user corresponding to a captured image captured by an imaging device provided for the first user or a view direction of a second user who views a surrounding captured image in which surroundings of a position where the first user exists are captured as the captured image. The present disclosure can be applied to, for example, devices constituting a system that shares view information.
