Smartwatches can be quite handy, but they do have a small screen, so you are not going to be able to navigate menus or enter information on your watch as easily as you can on your smartphone or tablet. What if you didn’t have to even touch your smartwatch to interact with it? That’s what Skin Buttons are all about. By integrating laser projectors into a smartwatch, you can project touch sensitive icons on your skin.
The developers behind this project promise high touch accuracy. Such a system could also save battery life since your smartwatch does not need to have its display on to work. A pretty innovative solution if you ask us.
