INTELLIGENT software that brings rough sketches to life in a virtual world is promising to revolutionise the way children learn and to help engineers visualise their designs.
In designing the software, developers at the Massachusetts Institute of Technology have had to tackle several tough tasks. First the software must recognise crude hand-drawn shapes in the way the user intended – for example, by spotting that four wiggly lines represent a square with straight sides.
