Interesting methodology: "To investigate, I used a small Teensy microcontroller to measure click-to-photon latency. It acts as a USB HID mouse and is paired with a light sensor pressed against the screen. I flashed it with an existing Open Source LDAT sketch, with slight modifications. The resulting setup can log hundreds of samples to a CSV file, unattended."
