Showing a new smart phone is one of the best parts to enhance your mobile device, but you can use your phone without having to leave your pocket? This is the future that German scientists target Hasso Plattner Institute, with the first prototype of what they call the “imaginary phone.”

The system uses the current smartphone (iPhone has been used in the prototype), and maps the touch screen in the palm of your hand. Then just touch the palm of your hand you would normally touch the screen. The phone, the input is as if you were touching yourself, so you can answer calls (via speakerphone), and even run applications.

While that may seem black magic – the above video does a good job of hiding the bulky hardware prototype – the current system requires the user to wear a helmet tall, with a depth and motion detection camera, and a wireless transmitter sends input gesture to the phone itself.

So that the system would be useful first of all, a person is intimately familiar with your smartphone. During the test, the research team found that users who have had to save the status icons on their phones were successfully launch the application you want 4 of 5 times. So even though there is clearly some role in making the system a little ‘portable and easy to use, it can respond to the palm of your hand before you know it.
