To provide a technique for determining an identity of an object gazed by a gaze person in different time ranges.SOLUTION: A gaze object identity determination device A is comprised of: a line-of-sight data acquisition unit 1 that acquires line-of-sight data of a gaze person at each time; a line-of-sight data dividing unit 2 that divides the line-of-sight data into a line-of-sight data set for each time range in which the object is continuously gazed; an approximate line calculation unit 3 that calculates an approximate line in space-time from the line-of-sight data belonging to the time range; and an object identity determination unit 4 for determining an identity of an object gazed in the first time range and an object gaze in the second time range by comparing a first approximation line in the first time range with a second approximation line in the second time range.SELECTED DRAWING: Figure 1

    【課題】異なる時刻範囲において注視者によって注視された対象物の同一性を判定する技術を提供する。【解決手段】注視対象物同一性判定装置Aは、各時刻における注視者の視線データを取得する視線データ取得部1と、視線データを、対象物を連続して注視している時刻範囲毎の視線データ集合に分割する視線データ分割部2と、時刻範囲に属する視線データから、時空間における近似線を算出する近似線算出部3と、第1の時刻範囲における第1の近似線と、第2の時刻範囲における第2の近似線とを比較することにより、第1の時刻範囲において注視された対象物と、第2の時刻範囲において注視された対象物との同一性を判定する対象物同一性判定部4と、を備えている。【選択図】図1
