  • Whirling interfaces: Smartphones & tablets as spinnable affordances, 
Abstract

Interfaces featuring smartphones and tablets that use magnetometer-derived orientation sensing can be used to modulate virtual displays. Embedding such devices into a spinnable affordance allows a “spinning plate”-style interface, a novel interaction technique. Either static (pointing) or dynamic (whirled) mode can be used to control multimodal display, including panoramic and turnoramic images, the positions of avatars in virtual environments, and spatial sound. “Spinning,” in which a flatish object is whirled with an extended finger or stick, is a disappearing art. We hope to re-motivate this vanishing skill, modernizing it and opening it up to internetamplified multimedia. The ubiquity of the modern smartphone makes it an attractive platform for even location-based attractions. We are experimenting with embedding mobile devices into suitable affordances that encourage their spinning. Using azimuthal (yaw) tracking especially allows such devices to control horizontal planar displays such as periphonic spatial sound, as well as avatar heading and (QTVR-style) panoramic and turnoramic imaged-based rendering.
