The present invention addresses the problem of more appropriately determining posture information of a user model. An
information processing device is provided with: an acquisition unit that acquires information indicating a construction angle of a human model and information indicating a height of a hand of the human model; and a determination unit that, on the basis of the information indicating the construction angle, determines whether construction is performed on a wall surface or on a ground surface, determines that the human model is in a
squat state when the height of the hand of the human model is lower than a first threshold value when the wall surface is constructed, and determines that the human model is in a
squat state when the ground surface is constructed, and determines that the human model is in a non-
squat state when the height of the hand of the human model is lower than the first threshold value when the ground surface is constructed. When the height of the hand of the human model is lower than a second threshold value lower than the first threshold value, it is determined that the human model is in a squatting state, and the height of the
waist of the human model is determined by
artificial intelligence or the like on the basis of whether the construction is performed on the wall surface or the ground surface and whether the human model is in the squatting state.
