Abstract:
An operation input device comprising:back-of-hand detection means which is mounted on a back of a hand of an operator to detect a motion or posture of the back of the hand of the operator; spatial coordinate computation means for obtaining a position or posture of the back of the hand of the operator in a three-dimensional coordinate system on the basis of an output from said back-of-hand detection means; finger posture detection means which is mounted near a tip of a finger of the operator and which has a uniaxial sensor that detects a posture of the finger of the operator in a one-axis direction; finger shape estimation means for computing the posture of the finger with respect to the back of the hand of the operator from an output from said finger posture detection means by using an output from said spatial coordinate computation means; hand shape estimation means for obtaining an overall shape of the hand of the operator on the basis of the outputs from said back-of-hand detection means and said finger shape estimation means; and operation input analysis means for generating a command by a predetermined scheme on the basis of the outputs from said hand shape estimation means and said spatial coordinate computation means.
