許多公司都在競相開發虛擬現實 (VR)，因為他們認為它具有巨大的工業潛力。然而，VR應用的加速並沒有帶來客戶體驗的發展。由眼睛衝突引起的疲勞，仍然成為 VR 用戶感到的一個自然問題。而實際上，這種情況可以通過調整視差來最小化。此外，沒有特別的指南規定使用 VR 來防止視覺疲勞的最長時間。本研究旨在驗證 VR 環境和內部任務對視覺疲勞的影響。客觀測量和主觀測量分別應用於靜態和動態場景。臨界閃爍融合頻率、眼睛注視、眼睛掃視和眨眼率用於測量眼睛處理疲勞的能力。這項研究有望找出 VR 環境中的任務類型和視差與視覺疲勞之間的關係。這個結果可以被 VR 開發者用作未來開發 VR 時的關注點。對眼睛注視持續時間的實驗結果表明，視覺疲勞受任務類型的影響顯著。

Many companies are competing to develop Virtual Reality (VR) because they see it as a great industrial potential. However, the acceleration of VR applications does not come up with customer experiences development. Fatigue, which generated by eye conflict, is still becoming a natural problem that the VR user feels. While actually, this condition can be minimized by adjusting the parallax. Furthermore, no particular guideline has stated the maximum duration of using VR to prevent visual fatigue. This research is aimed to validate the effect of the VR environment and the task inside towards visual fatigue. Objective and subjective measurement is applied respectively into the static and dynamic scenario. Critical Flicker Fusion Frequency, Eye Fixation, Eye Saccades, and Eye Blink Rate are used to measure the eye capability to handle the fatigue. This research is expected to find out the relationship between task type and parallax inside the VR environment to visual fatigue. This result can be used by the VR developer as a concern when developing VR in the future. The experimental results of analysing the eye fixation duration showed that visual fatigue affected by the type of task significantly.
