Vibrative Is An Invisible Keyboard For Your iPhone That Works By Analyzing Vibrations [VIDEO]

Before the official launch of the iPhone 5, Fox News reported that the iPhone 5 would come with a laser keyboard and a holographic display. Although this report was totally bogus and yet another sign Fox doesn’t do any sort of research before reporting on something, if you thought the idea of a laser keyboard was cool you will like what I am about to share with you.

According to The Telegraph a student by the name of Florian Kraeutli has developed software that allows a Jailbroken iPhone to turn any table into an invisible full-sized keyboard by analyzing vibrations caused by fingers tapping the surface with the iPhone’s accelerometer. Kraeutli elaborates, “The signals I’m collecting are very weak. At the moment it’s more of a proof of concept but if you made the accelerometer more sensitive you could improve the accuracy quite easily.”

Apparently the system, dubbed Vibrative, needs to learn the vibration patterns for each surface it is put on, but does not necessarily need to be taught the patten for each key individually. “Ideally you would train each key, but you can do just a couple,” says Kraeutli.

At this time Vibrative is more accurate on smaller surfaces, which vibrate more with each tap. As mentioned previously, the accuracy could be easily improved, but a more sensitive accelerometer would be required. Kraeutli suggests that accelerometers in smartphones may be set to be less sensitive than they are capable of to conserve battery power.

You can take a look at the demonstration video below of Vibrative in action. It is pretty impressive to say the least.

The same method used to make this invisible smartphone keyboard work on the iPhone could apparently be easily converted to other smartphones. Pretty cool, huh? Drop us a line with your thoughts in the comments below.

    It’s a cool proof of concept, but you’d think any acoustic change in the desk (setting a drink down, for example) would throw off the calibration.
