摘要：
PROBLEM TO BE SOLVED: To provide a direction indication device which operates a screen of a computer through a head or horizontal/vertical motion of eyes of a user, and a direction indication method.SOLUTION: A direction indication device comprises: a camera (imaging means) 3 for capturing an image of a face area of an operator； first coordinate system setting means 5 and second coordinate system setting means 6 for setting a first coordinate system of the face area imaged by the imaging means and a second coordinate system of an eye area in the face area； first delay means 7 and second delay means 8 for, in association with the movement of the eye area, delay-processing an original point coordinate of the second coordinate system moving while delaying following that, and for obtaining third and fourth coordinate systems different in delay time； first calculation means 9 and second calculation means 10 for calculating a movement amount and movement speed of an iris center in the third and fourth coordinate systems； discrimination means 11 for performing operation discrimination based on distance between original points of the third and fourth coordinate systems； and first to fourth determination means 12, 13, 14 and 15 for determining a horizontal direction or a vertical direction by a head or an eyeball on the basis of a signal from the discrimination means.SELECTED DRAWING: Figure 2【課題】ユーザーの頭部又は目の左右上下運動によりコンピュータの画面を操作する方向指示装置及び方向指示方法を提供する。【解決手段】方向指示装置は、操作者の顔領域を撮像するカメラ（撮像手段）３と、撮像手段により撮像された顔領域の第１座標系及び顔領域における目領域の第２座標系を設定する第1座標系設定手段５、第２座標系設定手段６と、目領域の移動に伴って、これに追随し遅延して移動する第２座標系の原点座標を遅延処理し、遅延時間の異なる第３、第４座標系を得る第１遅延手段７、第２遅延手段８と、第３、第4座標系における虹彩中心の移動量と移動速度を算出する第１算出手段９、第２算出手段１０と、第３座標系と第４座標系の原点間距離に基づく動作判別を行う判別手段１１と、判別手段からの信号に基づき頭部又は眼球による左右方向指示又は上下方向指示を判定する第１ないし第４判定手段１２、１３、１４、１５とを有する。【選択図】図２
