The pen would use accelerometer sensors, device storage and wireless transmission to send handwritten notes from the stylus to a digital display, according to the patent, first spotted by Apple Insider. In theory, the pen would let you write on a notepad and then view your work on, say, the screen of an iPad. The stylus would also work with different tips, so users could write using pencil, pen or marker.
Similar “smart” pens already exist. The LiveScribe 3, for example, can digitally capture written notes, as long as users write on a special type of paper. What would set the Apple stylus apart is that it could work on any surface, thanks to 3D motion sensors. Theoretically, someone could write on a table or even in the air, and the words would be transferred to a digital device.
Rumors abound about an iPad Air 2 with a larger screen, which could possibly hit stores in spring of 2015. A bigger iPad would be a perfect companion for such a stylus outlined in the patent; the Adobe Ink and Slide digital drawing tools, for example, are often used with tablets.
Of course, companies file patents all the time and are constantly developing technology that may never hit the market. So it’s unclear whether Apple is merely covering its bases or if we’ll be seeing a Cupertino-approved smart pen in the near future. Read more…
