Figure 4.

Illustrative contrast crosstalk measurements from two systems. Circles represent measurements through the stimulated goggle, and squares show measurements through the nonstimulated goggle. The Iiyama CRT monitor (left) shows positive crosstalk (the slope of the nonstimulated eye is positive). The VIEWPixx LCD monitor (right) shows negative crosstalk (the slope of the nonstimulated eye is negative). In all cases, x-axis values are the requested luminance of the stimulated eye, and the nonstimulated eye had a requested luminance of 0.5. The solid lines are best-fit regression lines.
