Abstract

An operation input device includes a back-of-hand detection section, spatial coordinate computation section, finger posture detection section, finger shape estimation section, hand shape estimation section, and operation input analysis section. The back-of-hand detection section is mounted on the back of the hand of an operator to detect the motion or posture of the back of the hand. The spatial coordinate computation section obtains the position or posture of the back of the hand in a three-dimensional coordinate system on the basis of an output from the back-of-hand detection section. The finger posture detection section is mounted near the tip of a finger of the operator to detect the posture of the finger. The finger shape estimation section computes the posture of the finger with respect to the back of the hand of the operator from an output from the finger posture detection section by using an output from the spatial coordinate computation section. The hand shape estimation section obtains the overall shape of the hand of the operator on the basis of the outputs from the back-of-hand detection section and the finger shape estimation section. The operation input analysis section generates a command by a predetermined scheme on the basis of the outputs from the hand shape estimation section and the spatial coordinate computation section.
