GESTURE OPERATION INPUT SYSTEM AND GESTURE OPERATION INPUT METHOD

摘要

A pointing position extraction unit (10) extracts a pointing position of a user from an image taken of gestures of the user looking at a display. A distance calculation unit (20) calculates a distance up to the pointing position in the depth direction. A gesture recognition parameter adjustment unit (50) adjusts parameters of sensitivity for detection in the depth direction when the gesture operation input by the user is recognized on the basis of at least one of a resolution of distance measurement in the depth direction and a 3D display performance of a display. A gesture recognition unit (60) recognizes the gesture operation input by the user in the adjusted parameters by referring to the distance up to the pointing position in the depth direction calculated by the distance calculation unit (20).
