Title:
POSTURE DETERMINATION DEVICE, POSTURE DETERMINATION SYSTEM, AND PROGRAM
Document Type and Number:
Japanese Patent JP2016104074
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To more accurately determine a degree of inclination of a posture in longitudinal and lateral directions of a person than in a case where a gravity center of pressure of a seat surface is detected, when determining the posture of the person in a seated state.SOLUTION: A position information acquisition part 401 acquires position information indicating a position of a predetermined region of a body of a person in a seated state. A pressure information acquisition part 402 acquires pressure information indicating the distribution of pressure values at a plurality of points in a seat surface on which the person is seated. A first peak value extraction part 404 extracts a maximum value of the pressure values in the seat surface as a first peak value. A second peak value extraction part 405 extracts a candidate pressure value as a second peak value when it coincides with a predetermined condition. Based on the position information, a total value of pressure values in a first region whose center is the coordinates of the first peak value, and a total value of pressure values in a second region whose center is the coordinates of the second peak value, a degree-of-inclination calculation part 407 calculates a degree of inclination in longitudinal and lateral directions of the person in a seated state.SELECTED DRAWING: Figure 3
