The LabMaestro Simulator is a software tool that allows researchers to test and debug experiment code without a physical connection to their data acquisition hardware. In this talk, Dr. Lindsey Fraser explains the rationale behind the simulator and what devices and features it replicates. She also outlines the overall licensing structure for the Simulator.

This talk was originally presented at a satellite talk for the 2021 virtual meeting of the Vision Sciences Society, which took place between May 21st and 26th 2021. This talk was presented live over Zoom on May 25th at 12:00 EDT. The video below is a recorded version of the talk that has been edited and streamlined for clarity.
