I think this is the first TED talk I ever watched, and it still remains one of my favourites:
Yet another fascinating TED talk about a technology that may allow us to get rid of most of the wires and batteries in our house. I didn’t know this was possible, but I’m very pleasantly surprised that it is.
David Merrill, a PhD student at the MIT Media Lab, gave a talk on the latest research project that he and his colleagues have been working on: Siftables.
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.
