Apple says it can be used anywhere if it can make apple pencil detect when in contact with the surface, move, etc., and then transmit it.

Artists are no longer limited to the relatively smallIPadOn the screen, you can sketch on a whole table, and that picture can be accurately drawn on the device. Artists can trace the existing drawings or plans, or they can trace such objects in real life to produce 3D images of objects.

Apple said the down and up and down positions of the touch on non touch sensitive surfaces could be monitored by the input device's force sensor. The position and / or motion of the input device can be tracked according to various methods, including one or more of motion and direction sensors, cameras, or triangulation schemes based on electromagnetic or sound.

All of these can be used for drawing or writing as well, and may even be sketched in thin air. Apple said in the patent that in some embodiments, content can be generated based on tracking the position and / or movement of the input device without contact with the surface.

However, apple does not intend to replace the touch screen, but thinks that this way to improve apple pencil, especially the active touch pen, can make the touch sensitive device sense the touch pen stimulus signal, and improve the accuracy of the touch pen input.
