Title:
INFORMATION PROCESSING APPARATUS, INFORMATION PROCESSING METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2022/163801
Kind Code:
A1
Abstract:
The present disclosure relates to an information processing apparatus, an information processing method, and a program with which it is possible to measure position and attitude using audio, without causing discomfort to the user. A spread code signal obtained by performing spread spectrum modulation on a spread code, the spread code signal having been emitted as sound from a plurality of audio output blocks present at known positions and shifted to a frequency band difficult to recognize by human auditory perception, is received. The spread code signal of the received audio signal is subjected to inverse-shift processing, and one's own absolute position and absolute attitude are calculated on the basis of the inverse-shifted spread code signal and an angular velocity and acceleration detected by an IMU. The present invention may be applied to game controllers and HMDs.
