Do IPT Systems Fulfill Application Requirements? A Study on Luminance on Large-Scale Immersive Projection Devices

Luminance and contrast are very important characteristis of immersive display devices and have great impact on the perceived quality of an immersive VR presentation. In this paper, we report on results from measurements we performed on a passive large-screen front projection and in a five-sided CAVE. Weexamined luminance range and color representation as well as luminace distribution across the screen, interreflection effects, and other properties. Implications of the measured values are explained, taking into account the perceptual issues of the human visual system, and example applications are presented. Based on the results, the critical aspects for the visual quality of large-scale immersive projection devices are identified.
