Abstract

We have built haptic interfaces featuring smartphones and tablets that use magnetometer-derived orientation sensing to modulate virtual displays, especially spatial sound, allowing, for instance, each side of a karaoke recording to be separately steered around a periphonic (circumferential) display. Embedding such devices into a spinnable affordance allows a “spinning plate”-style interface, a novel interaction technique. Either static (pointing) or dynamic (spinning) mode can be used to control “whirled” multimodal display, including a rotary motion platform, panoramic movies, and the positions of avatars in virtual environments.
