Researchers at Carnegie Mellon University in Pittsburgh are developing an innovative solution to the challenge of working with a one inch screen on a smartwatch.
Robert Xiao a Ph.D. candidate in the Human-Computer Interaction Institute at Carnegie Mellon University, has unveiled the first fully-functional and self-contained projection smartwatch.
The timepiece not only projects images onto a wearer’s arm, it allows them to interact with the image as if it were touchscreen.
Users are able to swipe to unlock the device and use apps, as well as track 2D finger movements.
The engineer claims the wristwatch offers approximately 40 square centimeters of interactive surface area, which is more than five times that of a typical smartwatch display.
A video demonstrating the smartwatch, which was presented at the SIGCHI conference in April 2018, can be found below.
