New acoustic alternative for touchscreen phones in development

(PhysOrg.com) -- Acoustic engineers have for years been tinkering with the idea of using pulse recognition as a means for interacting with machines, but until now, little progress has been made in converting such ideas into a working device. Now, Jens Christensen, of Cambridge University, has won the Innovation for Sustainability category as part of the Information and Communications Technology (ICT) Pioneer awards from the Engineering and Physical Sciences Research Council (EPSRC) in London, for his TouchDevice which uses software to convert a regular cell phone into one capable of carrying out many touchscreen features.
