University of California, San Diego researchers have demonstrated a new user interface technology: electronic recording and replay of human touch.
“Touch was largely bypassed by the digital revolution, except for touch-screen displays, because it seemed too difficult to replicate what analog haptic [touch] devices can produce,” said Deli Wang, a professor of Electrical and Computer Engineering (ECE) in UC San Diego’s Jacobs School of Engineering and senior author of a Nature Scientific Reports paper (open access) on this research.
“Being able to reproduce the sense of touch in connection with audio and visual information could create a new communications revolution.
“Communication of touch signals could have far-reaching implications for health and medicine, education, social networking, e-commerce, robotics, gaming, and military applications, among others,” said Wang.
The sensors and sensor arrays reported in the paper are also fully transparent, making them useful for future touch-screen applications, especially in mobile devices.
