PROBLEM TO BE SOLVED: To provide a visual line estimation device capable of estimating a more accurate visual line, etc.SOLUTION: A visual line estimation device includes a contact position specification part, an imaging part, and a processing part. The contact position specification part specifies a contact position which is a position where a person makes a contact with an object. The imaging part takes an image of a part including eyes of the person when he or she makes a contact. The processing part estimates a line that passes through the contact position and is parallel to the direction of a visual line of the eyes derived from the image as the visual line of the eyes.SELECTED DRAWING: Figure 1【課題】より正確な視線の推定を行い得る視線推定装置等の提供。【解決手段】 本発明の視線推定装置は、接触位置特定部と、撮像部と、処理部と、を備える。前記接触位置特定部は、人が物への接触を行った位置である接触位置を特定する。前記撮像部は、前記接触の際の前記人の目を含む部分の撮像を行う。前記処理部は、前記接触位置を通り、前記画像から導出した前記目の視線の方向と平行な直線を、前記目の視線と推定する。【選択図】 図1
