Shoogle is a novel, intuitive interface for sensing data within a mobile device, such as presence and properties of text messages or remaining resources. It is based around active exploration: devices are shaken, revealing the contents rattling around "inside".

Vibrotactile display and realistic impact sonification create a compelling system. Inertial sensing is used for completely eyes-free, single-handed interaction that is entirely natural. Prototypes are running both on a PDA and on a mobile phone with a wireless sensor pack. This is a general technique for coupling inference mechanisms and multimodal interaction.
