Generalizeability of Latency Detection in a Variety of Virtual Environments

User perceptual sensitivity to changes of full system latency was tested in three simple virtual environments, two with ei-ther only a foreground or a background object and an additional one that combined both types. Earlier psychophysical measurements of sensitivity (just noticeable differences) and bias (points of subjective equality) are confirmed and con-trasted with other reports in which subjects may not have been sufficiently instructed as to what the visual consequences of latency were. A possible explanation of these dif-ferences could have been related to a visual capture effect reported initially by Matin. This possibility is discounted by precise measures of bias and sensitivity in 13 subjects. Results based on rigorous psychophysical measurements support earlier claims that per-ceptual stability within a variety of virtual envi-ronments will require latencies less than 16 ms.
