Google is a little bit obsessed with trying to make sure that the experience of using its Android and Chrome OS devices is as enjoyable as possible. To that end, the company has been carrying out tests that it hopes will show the latency endured when a user touches a screen, with the time taken between press and something being drawn on screen being measured. Google may not have been making too much noise about this testing process and you can be assured that other companies are doing the same thing with their platforms, but Google is the first to give us a look behind the curtain.
