Abstract

Contemporary smartphones and tablets have magnetometers that can be used to detect yaw, which data can be distributed to adjust ambient media. We have built haptic interfaces featuring smartphones and tablets that use compass-derived orientation sensing to modulate virtual displays. Embedding mobile devices into pointing, swinging, and flailing affordances allows “padiddle“-style interfaces, finger spinning, and “poi“-style interfaces, whirling tethered devices, for novel interaction techniques [Cohen et al. 2013].
