Abstract: 
液晶ディスプレイによる動画表示は特有の「ぼやけ」や「にじみ」を伴うという欠点があったが, OCB液晶技術によって開発されたディスプレイはこの問題を解消した. そこで, OCB液晶ディスプレイと従来からの液晶ディスプレイについて, 高齢者から若年者までの幅広い年齢層を対象として, 動画を注視している際の重心動揺の測定を行った. 被験者は, 20歳から73歳の正常裸眼視力または正常な矯正視力を有するとともに, 平衡機能に既往症のない55名を対象とした. OCB液晶ディスプレイと従来からの液晶ディスプレイには, 横方向にスクロールする地図を表示した. 重心動揺の測定結果は, 定量化指標を用いて比較検討を行った. その結果, OCBディスプレイと従来型ディスプレイの間に差が認められ, OCBディスプレイ注視時は重心の不安定さが改善されたことが示された. この傾向は, 若年層で著しく, 中年層と高齢者では従来型ディスプレイ注視時とOCBディスプレイ注視時との差異は有意ではなかった.

TL;DR: It is believed that it will be easier to detect VIMS symptoms induced by DS operations if the index can be used for an eye-tracking data-based evaluation of VIMs.

TL;DR: From the dynamic relationships between the velocity of the moving visual scene and the amplitude of sway, it was concluded that the postural readjustment is proportional to a low pass filtering of the logarithm of the velocity.

TL;DR: This experiment showed that dynamic discrimination peaked at age 15 and then declined at a constant rate from age 20 on, and speculated that males may have better discrimination than females but variability is substantial.

TL;DR: The data suggested that heart period, tachygastria, and skin conductance level were more sensitive to simulator sickness than were vagal tone and normal myoelectrical gastric activity.
