Results from 10 adults who completed three tests with ASTEROID (vertical axis) and three tests with an equivalent test presented on a stereoscopic 3D TV (horizontal axis). Data points show the mean of the three values obtained from each test (mean of log arcsecond) and error bars show ±1 SD. The solid line shows the identity, that is, perfect agreement. The dotted line shows the identity offset by the mean difference between the results, while the dashed lines show the Bland-Altman 95% limits of agreement between the two tests, that is, the mean difference ± 1.96 times the standard deviation of the difference. Means are computed on log thresholds, which correspond to the geometric mean of the thresholds in arcseconds.
