Magnetically Driven Pen

MagPen is a magnetically driven pen interface that works both on and around mobile devices. The device introduces a new vocabulary of gestures and techniques that redefine the way we use our current standard capacitive stylus. With this new pen we can explore ranges like detecting the orientation the stylus is pointing to, selecting colors using locations beyond the screen boundaries and more.

MagPen recognizing different spinning gestures associated with different actions, it even infers the pressure applied to the pen, and uniquely identifies different pens associated with different operational modes.

As the designer explains, These techniques are achieved using commonly available smartphones that sense and analyze the magnetic field produced by a permanent magnet embedded in a standard capacitive stylus. This paper explores how magnets can be used to expand the design space of current pen interaction, and proposes a new technology to achieve such results.
