Effects of characteristics of image quality in an immersive environment

Image quality issues such as Želd 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 difŽculty ratings varied as a function of FOV, scene content, and image resolution. Subjects exhibited more balance disturbance and reported more difŽculty in maintaining posture in the wide-FOV, highresolution, and natural scene conditions.
