Scientists create 'floating pixels' using soundwaves and force fields 2016


A mid-air display of 'floating pixels' has been created by scientists.
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.
