On May 24, 2012, the US Patent & Trademark Office published a patent application from Apple that sheds more light on their future iPen and related graphics program. Apple continues to spend time and R&D funding on a future iPen device that's being designed to work with all of Apple's tablet-styled iDevices. The focus found in today's invention is twofold. Firstly, Apple is thinking of adding advanced haptics to the iPen so that the end user will be able to feel brush strokes and/or line thicknesses for example. Secondly, Apple is designing the iPen with a built-in mini speaker so as to provide users with various forms of audio feedback. To make all of this interesting and relevant, Apple sheds a little light on how their iPen will work with either a new graphics/paint program of their own and/or with known apps such as Autodesk and Microsoft's Paint.
