Google Uses a Robot to Test Android Phones for Lag

Lag on Android has been a problem for some time now; even if you're using a flagship phone, and especially after you're used it for a couple of months. Google plans to address this head on though, as per a Google Plus post by Francois Beaufort, a Chromium Evangelist at Google.
In the post, Beaufort has included a video titled Chrome Touchbot, that explains how Google uses a robot to test for lag.
The robot, manufactured by Finnish company OptoFidelity, measures the end-to-end latency of Android and Chrome OS devices, according to Beaufort's post. The video, captured by a high-speed video camera shows how drawing a line on a screen is done in segments that fade in slowly. You can see the test in the video below:
