Video: NailDisplay gives you a “see through thumb”.
The NailDisplay is envisaged as being a permanently mounted display on a users thumbnail, giving the wearer a variety of different ways to interact with technology.
In one scenario the display shows the user what’s showing on a touchscreen behind their nail, solving the problem of trying to use a small display like on an iPod Nano, with a large thumbnail blocking the screen.
In other scenarios the display allows the user to see an imaginary interface on the users hand or arm, allowing their body to be effectively used as a touchscreen to control music or other apps via a smartphone. It also allows for swiping and other gestures in mid-air.
