In stubborn Apple in 2015, a pressure-sensitive stylus was introduced, but so far the pen is now only available on the iPad Pro, which makes Apple's pen a bit embarrassed as a separate accessory.
However, Apple also did not intend to idle, recently, in the WIPO (World Intellectual Property Organization) database, it was found a new patent (US20180018057) .This patent by Apple's three engineers, entitled "on the non-electronic surface Using electronic input devices for creative '.
From the drawings we can see that the title means using a special pen to write and draw anywhere, and then through the sensor to create the content input to the electronic device.
And this special pen can also be used in a variety of Apple devices, but the specific how to use, Apple has deliberately vaguely did not make it clear, just say 'motion and direction based sensor, camera or electromagnetic induction'.
The file also states that it is possible to use this special pen without media because it tracks the motion in three dimensions, meaning that you can create content directly in the air and have a bit of a HalWar magic wand.
However, this is only a patent disclosed at present, specifically whether it can become an actual product has to look at Cook's mood slightly.
