Siftables aims to enable people to interact with information and media in a physical, natural manner that ap­proaches interactions with physical objects in our everyday lives. As an interaction platform, Siftables applies technology and methodology from wireless sensor networks to tangible user interfaces. Siftables are inde­pendent, compact devices with sensing, graphical display, and wireless communication capabilities. They can be physically manipulated as a group to interact with digital information and media. Siftables can be used to imple­ment any number of gestural interaction languages and HCI applications.
