Provided is an information input device whereby visible laser light which projects an information input image is prevented from irradiating a face or an eye. The information input device includes a projection unit projecting an information input image with visible laser light, a movable support unit mounting the projection unit thereon so that a projection position of the information input image by the projection unit can be changed, a first sensing unit capturing an image of a sensing region within which the information input image can be projected, a second sensing unit which is mounted on the movable support unit and detects an object entering a predetermined region containing the projection position of the information input image and a distance to the object, an information input detection unit detecting information input by identifying, based on image data captured by the first sensing unit, an input operation being performed on the information input image, and an identification control unit which identifies, based on information acquired by the second sensing unit, the presence or absence of a particular object entering the predetermined region and, if the entering of a particular object is detected, then causes the projection unit to stop projecting the information input image. |

1. An information input device comprising:
a projection unit which projects an information input image by using visible laser light; a movable support unit which mounts the projection unit thereon in such a manner that a projection position on which the information input image is to be projected by the projection unit can be changed; a first sensing unit which captures an image of a sensing region within which the information input image can be projected; a second sensing unit which is mounted on the movable support unit, and which detects an object entering a predetermined region containing the projection position of the information input image and detects a distance to the object; an information input detection unit which detects information input by identifying, based on image data captured by the first sensing unit, an image of an input operation being performed on the information input image; and an identification control unit which identifies, based on information acquired by the second sensing unit, the presence or absence of a particular object entering the predetermined region and, if the entering of a particular object is detected, then causes the projection unit to stop projecting the information input image. |
