Smartwatches are going to become a lot more popular in the next few years. But don’t expect them to get much bigger like phones and phablets. Using these tiny screen devices does not have to be difficult. An off-screen set of controls would allow you to use these watches more conveniently. That’s what Skin Buttons is all about. We are talking about tiny laser projectors integrated into a smartwatch to project icons on your skin. These icons can be made touch-sensitive, allowing you to interact with your smartwatch more conveniently.
Skin buttons can be used for many functions, allowing users to interact with their smartwatch without having to touch its screen. The developers suggest the system can be made to have a negligible impact on battery life. Now that sounds exciting.
