NTT is developing RedTacton, a new human area networking technology that allows devices to communicate through touch over short distances. RedTacton uses the human body and various conductors or dielectrics as transmission media to enable touch-triggered interactions between devices at speeds up to 10Mbps. It has applications for instant data sharing, intuitive device operation, personalized automobiles that load user settings automatically, and security systems that authenticate users with a touch. RedTacton could provide more secure and convenient connectivity than existing local network technologies.
