“Researchers at the Universities of Sussex and Bristol have used soundwaves to lift many tiny objects at once before spinning and flipping them using electric force fields. The technology – called JOLED - effectively turns tiny, multi-coloured spheres into real-life pixels, which can form into floating displays or bring computer game characters to life as physical objects. To be presented next week at a future technologies conference in Japan, the research opens up new possibilities for mobile and game designers, giving them a new way of representing digital information in a physical space.”
