Sony Ericsson wants you to tap your headset to your phone to activate it

Tapping may be the new way to interact two devices. Sony Ericsson’s patent application 11/972,712 teaches of a method for two devices to perform an “application specific action” when those two devices are tapped together. How is this useful? Well, let’s look at two examples cited by the patent application.
In the first diagram, we see how a headset may be tapped on a phone to activate it and perhaps tapped again to deactivate it. This is infinitely more convenient than navigating through the phone’s menu system.
The second diagram shows a more creative reason for tapping. Here, tapping two phones together spans the image across the two screens. Pretty cool huh?
