Description

From the listing uploaded by “appupdater”.

The Twhirleds app senses orientation of the mobile device, and can be used as a gestural interface for collateral software (available from the developers web site) for multimodal interfaces, including augmented virtuality scenes, panoramic and photo-spherical browsing, and spatial sound renderers. Static pointing can be used to control such modulation, but by embedding a mobile device (such as a tablet or smartphone) running Twhirleds into a twirlable affordance enables “padiddle’”-style interfaces, spinning flatish objects, and “poi”-style interfaces, whirling tethered devices.
