Patent Images
1. A data input device comprising:
- a projecting unit that projects images of a plurality of keys;
an instruction recognizing unit that recognizes whether any one of the images of the keys projected by the projecting unit has been designated by an operator;
a data input unit that accepts input of data corresponding to the image of the key recognized by the instruction recognizing unit; and
a controlling unit that controls any one of a position of a boundary between an image of an arbitrary key and an image of a key adjacent to the arbitrary key projected by the projecting unit;
a space between an instruction effective area of an image of an arbitrary key and an instruction effective area of an image of a key adjacent to the arbitrary key projected by the projecting unit; and
a size of an outlined arbitrary key image area projected by the projecting unit.

Abstract
Images of a plurality of keys are projected and it is recognized whether any one of the images of the keys projected is designated by an operator. When the operator designates an image, a controlling unit controls any one of: a position of a boundary between an image of an arbitrary key and an image of a key adjacent to the arbitrary key; a space between an instruction effective area of an image of an arbitrary key and an instruction effective area of an image of a key adjacent to the predetermined; and a size of an outlined arbitrary key image area.
