This paper proposes user-customizable passive control widgets, called MagGetz, which enable tangible interaction on and around mobile devices without requiring power or wireless connections. This is achieved by tracking and ana-lyzing the magnetic field generated by controllers attached on and around the device through a single magnetometer, which is(More)
This paper introduces <i>MagPen</i>, 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)(More)
In this paper, we present the <i>Magnetic Marionette</i>, a magnetically driven elastic controller that enables tangible interaction on mobile devices. This technique can determine eight different gestures in excess of 99% accuracy by sensing and tracking the magnets embedded on the controller. The advantage of this technique is that it is lightweight,(More)
