Operation input device
First Claim
1. An operation input device comprising:
- three-dimensional image display means for displaying a three-dimensional image in a predetermined virtual space;
one or more image pickup means for picking up an image in an area including the virtual space;
recognition means for recognizing a motion of a user'"'"' hand within the virtual space from the image picked up by the image pickup means; and
control means for driving the three-dimensional image display device to display a three-dimensional image for operation of a device to be operated, identifying an operation command issued by the user from the motion of the user'"'"'s hand recognized by the recognition means while the three-dimensional image is displayed, causing the three-dimensional image displayed by the three-dimensional image display means to change in accordance with the identified operation command, and outputting the operation command to the device to be operated.

Abstract
An operation input device includes a liquid crystal display and a Fresnel lens in combination to display a three-dimensional virtual image in a virtual space in front of a vehicle navigator'"'"' seat for allowing an occupant of the seat to input an operation command for an in-vehicle unit. An image of the occupant and the image in the virtual space are taken by an image pickup device. An ECU recognizes a motion of an occupant hand within the virtual space through an image processing operation performed against the picked-up images. When the recognized motion matches with a predetermined motion relative to the three-dimensional image displayed in the virtual space, it is determined by the ECU that an operation command for the in-vehicle unit has been inputted. The ECU outputs the operation command to the in-vehicle unit and changes the three-dimensional image in the virtual space according to the operation command.
