Title:
INFORMATION PROCESSING DEVICE, INFORMATION PROCESSING METHOD, PROGRAM, AND INFORMATION RECORDING MEDIUM
Document Type and Number:
WIPO Patent Application WO/2022/224586
Kind Code:
A1
Abstract:
Provided is an information processing device (101) that estimates the direction of the face of a user in the real world and outputs information corresponding to the estimation. The information processing device (101) comprises a camera (151). A detection unit (111) detects a first direction of the information processing device (101) in a first coordinate system fixed in the real world. When a photograph image photographed by the camera (151) includes a face image of the user, an estimation unit (112) estimates, from the photograph image and the face image, a second direction of the face of the user in a second coordinate system fixed with respect to the information processing device (101). A calculation unit (113) calculates a third direction of the face of the user in the first coordinate system from the detected first direction and the estimated second direction. An output unit (114) outputs information corresponding to the calculated third direction.
