Applicable VE-displays range from simple desktop monitors with low immersion to high-end, immersive HMDs. It is often inferred that more sophisticated displays always produce higher performance. In this paper this opinion is critically questioned. To estimate effectiveness and usability of the display measures of human performance, subjective workload, and simulator sickness serve as critical criteria. The effect of three different displays (desktop monitor, projection wall, HMD) with varying degrees of immersion on each of the criteria was analyzed empirically.
