Switching on a lamp is all it takes to turn a table-top into an interactive map with this clever display, on show at the SIGGRAPH computer graphics and animation conference in Los Angeles. Multi-touch table-top displays project content through glass and respond to touch – imagine a table-sized smartphone screen. But researchers from the National Taiwan University in Taipei wanted to make these types of screens more appealing for multiple users. The idea is that several people could look at the same images, and get more information about the areas that interest them, using moveable objects. Users viewing an image such as a map projected onto a table-top display can zoom in on specific areas – seeing street names for example – simply by positioning the lamp device over them.
