图像质量问题，如视场（FOV）和分辨率是重要的评估“存在”和模拟器病（SS）在虚拟环境（VE）。本研究探讨了在沉浸式视觉显示中，不同的视野、图像分辨率和场景内容对姿势稳定性的影响。使用六个FOV（30、60、90、120、150和180 °）测试两个不同分辨率的两个不同场景（喷泉的照片和简单的放射状图案）。这两个姿势的稳定性，记录的力板，主观难度等级变化的功能FOV，场景内容，和图像分辨率。受试者表现出更多的平衡障碍，并报告在宽FOV，高分辨率和自然场景条件下更难保持姿势。
Image quality issues such as field of view (FOV) and resolution are important for evaluating "presence" and simulator sickness (SS) in virtual environments (VEs). This research examined effects on postural stability of varying FOV, image resolution, and scene content in an immersive visual display. Two different scenes (a photograph of a fountain and a simple radial pattern) at two different resolutions were tested using six FOVs (30, 60, 90, 120, 150, and 180 deg.). Both postural stability, recorded by force plates, and subjective difficulty ratings varied as a function of FOV, scene content, and image resolution. Subjects exhibited more balance disturbance and reported more difficulty in maintaining posture in the wide-FOV, high-resolution, and natural scene conditions.
