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.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
