 note = {縦一列に固定された LED を高速に点滅させ，サッカードと呼ばれる高速眼球運動を利用して網膜上に 2 次元の画像を知覚させるラインディスプレイを開発してきた．本報告では，ラインディスプレイ観測時の眼球運動の角度を求めることを目的として，眼球運動測定装置 Pupil Core を装着し，瞳孔の動きを記録し，これをもとに眼球運動の角度を計算するプログラムを作成した．求めた角度の精度を実験で検証した結果，15[°] 以内の範囲では誤差が 0.6[°] 以下になった．また，夜間屋外でのラインディスプレイ観測実験では，被験者が Pupil Core を装着し，点滅周期を変化させたときの知覚の最適距離を測定した．点滅周期と最適距離，点滅周期と眼球運動の角度の関係を評価した結果，最適距離が長い被験者は角度が小さく，最適距離が短い被験者は角度が大きいことがわかった．, We have been developing a line display that perceives a two-dimensional image on the retina by using high-speed eye movements called saccades, which are caused by flashing LEDs fixed in a vertical row at high speed. In this report, we developed a program that calculates the angle of eye movement based on the pupil movement recorded by the Pupil Core, an eye movement measurement device, in order to determine the angle of eye movement during line display observation. The accuracy of the calculated angle was verified by experiments, and the error was less than 0.6 [°] within a range of 15 [°]. In the line display observation experiment outdoors at night, the subject wore the Pupil Core and the optimal distance of perception was measured when the flashing period was varied. As a result of evaluating the relationship between the blinking cycle and the optimal distance, and between the flashing cycle and the angle of eye movement, it was found that the angle was smaller for subjects with a longer optimal distance and larger for subjects with a shorter optimal distance.},
