Title:
INFORMATION PROCESSING DEVICE, INFORMATION PROCESSING METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2019/026597
Kind Code:
A1
Abstract:
This technology relates to an information processing device, an information processing method, and a program which make it possible to set a sound image at an appropriate position. This information processing device is provided with: a calculation unit which, on the basis of the position of a sound image of a virtual object that is perceived as being present in a real space by sound image localization, and the position of a user, calculates the relative position of a sound source of the virtual object with respect to the user; a sound image localization unit which performs sound signal processing of the sound source such that the sound image is localized at a calculated localization position; and a sound image position holding unit which holds the position of the sound image, wherein the calculation unit calculates the position of the sound image with reference to the position of the sound image held in the sound image position holding unit if, when sound generated by the virtual object is switched, the position of the sound image of the sound after switching is set at a position that succeeds the position of the sound image of the sound before switching. This technology is applicable, for example, to an information processing device that provides the entertainment of conversation with a virtual character.
