Is round the shape of monitors to come? Yes - if US-based startup Actuality Systems gets its way. It is set to unveil its 20-inch spherical display monitor at the Society for Information Display (SID) conference in San Jose this week, meaning beachball-shaped monitors are a future possiblilty. The display, code-named Helios, was designed to allow users to view three-dimensional imagery in higher detail than traditional flat computer screens. Users can move around the display and view the images from any angle across 360 degrees. The company said the three-dimensional imaging can be used for applications including visualization and imaging, as well as mechanical CAD (computer-assisted design), aeronautical and astronautical imaging in areas including air-traffic control and satellite positioning systems - and of course, entertainment. Actuality was formed in 1997 as a spin-off of the Massachusetts Institute of Technology Entrepreneurship Competition.
