“…Previous studies include a magnetic input technique that allows accurate selections for small screens [5], a magnetbased hand writing system [7], and a magnetic interface for musical performance [6]. While magnets definitely improve usability by expanding interactivity beyond the device screen [2], the main limitation of these approaches is that the interaction happens without requiring contact between the magnetic token and the device [5], leaving users without tactile feedback (i.e., drawing in the "air" as opposed to drawing on a "surface").…”

“…Researchers have long attempted to increase this input space to complement the lack of expressiveness seen in plain, touch-based interaction. These methods include magnetically augmented tokens [2], pressure-sensitive inputs [4,10], and gesture recognition systems [6,7,12]. In particular, magnetic-based interfaces [2,5,9] have proven to be very effective in expanding the expressiveness and scope of the input space.…”

This paper introduces MagPen, a magnetically driven pen interface that works both on and around mobile devices. The proposed device is accompanied by a new vocabulary of gestures and techniques that increase the expressiveness of the standard capacitive stylus. These techniques are: 1) detecting the orientation that the stylus is pointing to, 2) selecting colors using locations beyond screen boundaries, 3) recognizing different spinning gestures associated with different actions, 4) inferring the pressure being applied to the pen, and 5) identifying various pens associated with different operational modes. 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.
