Skin Buttons: A Smartwatch That Projects Touch-Sensitive Buttons onto Your Wrist Skin

 skin-smartwatch

Skin Buttons, developed by the find people over at Carnegie Mellon in the Future Interfaces Group, is a smartwatch that projects touchable buttons onto your wrist, expanding the watch’s interface.

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.

Wrists are like the nipples of your arm.

You touch my wrist the right way and I’ll pounce on top of you, ripping your clothes off in a mad feral fury.

Touch my wrist the wrong way and your finger winds up floating around my digestive system for a few hours. Mmm, finger foods. Sexy time or a snack, it’s a win-win for me.
