Carnegie Mellon University and ASU Tech present LumiWatch, the first fully-functional and self-contained projection smartwatch, providing a touchscreen interface right on your arm. LumiWatch was presented at the SIGCHI conference in April 2018.


Projectors have always been the most convenient way to create a temporary but large screen, which makes them the ideal way to improve the functionality of smartwatches where you only occasionally want a larger touchscreen. And the idea of having a temporary keyboard instantly appearing on my arm is science fiction I want to be science fact as soon as possible.
