Apple have worked hard to achieve an excellent level of precision with their iPad display, but detailed work, whether painting or note taking, can be tricky and often requires a great deal of zooming in and out of the canvas.

The Cregle iPen, an active stylus that is currently in need of fanancial backing, looks like quite a clever solution to this problem.

"The Cregle iPen transforms the iPad into a content creation device, not just a content consumption device. iPen is the first active digitizer stylus that allows you to write with precision directly on the iPad. Unlike the passive digitizer used in the typical iPad stylus, iPen writes like a real pen with accurate positioning and palm rejection features that passive products simply cannot achieve.

With the Cregle iPen’s active digitizer, the attached receiver picks up the iPen’s signal and its precise position as it hovers above the screen (whereas a passive stylus can be located only when the user touches the screen). This crucial advantage allows iPen to actively transmit 60 samples per second to pinpoint the pen’s exact location."
