Culminating four years of research, a team at Singapore's Nanyang Technological University has developed a technology that can turn a multitude of surfaces including wood, glass, aluminium, steel and even plastics into a low-cost multi-touch screen. The technology, named STATINA (for Speech Touch and Acoustic Tangible Interfaces for Next-generation Applications), is only a couple years away from reaching mass production.
