Skin Buttons: A smartwatch that projects touch-sensitive icons onto your skin
A team over at Carnegie Mellon in the Future Interfaces Group developed Skin Buttons, which is a smart watch that projects laser icons that are touch sensitive onto a person’s skin.
We present Skin Buttons, tiny laser projectors integrated into the smartwatch to render icons on the user’s skin. These icons can be made touch sensitive, significantly expanding the interactive region without increasing device size. We show a proof-of-concept device and demonstrate example applications. These “skin buttons” can have high touch accuracy and recognizability, while being low cost and power-efficient.
