Title:
INFORMATION PROCESSING METHOD, INFORMATION PROCESSING DEVICE, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2022/219881
Kind Code:
A1
Abstract:
This information processing method includes: acquiring a stream including first position/orientation information that indicates the position and orientation of a sound source and a sound signal that indicates the sound outputted by the sound source (S101); acquiring second position/orientation information that indicates the position and orientation of a user's head (S102); and performing a correction to reduce the rate of change of the speed with which the position or orientation indicated in the acquired second position/orientation information changes relative to the position or orientation of the sound source indicated in the first position/orientation information, thereby acquiring second position/orientation information that is used in three-dimensional acoustic processing on the sound signal, said processing using the first and second position/orientation information (S103).
