Testing motion events was never going to be easy task. You have two options, both of which suck. If you decide to use a mobile device equipped with an accelerometer you’ll be left stranded without your favourite debugging tools. Alternatively, if you decide to develop on your favourite computer you will find yourself up motion event creek without an accelerometer. That’s where Remote-Tilt comes in. By including a single line of JavaScript you can emulate device motion events in your test page which can either be a regular browser or even a mobile emulator.
