From last some weeks we are feeling some ground shakes right? Your iPhone, iPad and most newer mobile phones can work as basic seismometers, the same instrument that is used to measure the magnitude of earthquakes and volcanoes. You don’t need to install any apps, just the built-in web browser would sufficient.
OK, try this. Launch Google Chrome or the Safari browser on your mobile phone (or tablet) and then open this page. You should see a continuously moving waveform but if you slightly shake or tilt your mobile device, simulating seismic activity, the graph will capture these movements in real-time much like a seismograph.
Most newer mobile devices have built-in accelerometers and gyroscopes and as you move the physical hardware, the changes in the orientation of the device and acceleration are detected by the browser which are then mapped into the seismograph.
The orientation and motion data are in turn captured by the HTML5 Device Orientation and Device Motion events of the browser. This works mostly on mobile devices but if you are using Google Chrome on the desktop, you can turn on the Accelerator option under Sensors inside Chrome Dev Tools to simulate motion.
Now this is fun for me as a developer, Isn’t it ?
