Devices as interactive physical containers
John H. Williamson, Roderick Murray‐Smith, Stephen Hughes · 2007
Shoogle is a novel 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 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. Prototypes run on both PDA's a standard mobile phones with a wireless sensor pack.
