From the article: 'Elliptic plans to showcase their “Mimesign” technology at IFA in Berlin from the 3rd to 8th of September 2010. Mimesign will bring intuitive ways for people to interact with devices. The possibilities range from tablets, remote controls or in-car media controls. The interface is based on ultrasound technology and allows the user to remain in an unchanged state.'"
