FIGURE 9.
Analysis of the motion-artifact data. (a) The proportion of trials in which motion artifacts were reported in the Csim/Palt–2X protocol is plotted as a function of capture rate and object speed. The proportion is indicated by the size of the data symbols, larger symbols for higher proportions. ×’s indicate conditions in which motion artifacts were never reported. (b) The same data are fit with a 3-D cumulative Gaussian and plotted as a stereogram. To see the figure in depth, cross-fuse (i.e., direct the right eye to the left panel and left eye to the right panel). The green line marks the positions on the fitted function where the observer reported artifacts on half the presentations.
