One of the important characteristics of a window- and gaze-contingent tool is the speed of reaction to the pointer or eye movements and the update delay—the so-called latency—of the contingent response. Here we demonstrate a handy possibility for measuring the latency of gaze-contingent or mouse-based software. We present a low-cost latency-measurement system that can be useful for studies that include eye-movement tracking tools. In our demonstration we use this system for measuring the latency of a gaze-contingent tool.
