A fingernail-based display could revolutionize the way people use devices such as smartphones.
National Taiwan University researchers have developed NailDisplay, a prototype 1-inch organic light-emitting diode screen that attaches to a ring that is worn on the thumb. The researchers eventually hope to coat fingertips in organic light-emitting materials and wirelessly beam content directly to the nail.
NailDisplay is designed to enable people to see what is on the screen of their device when their thumbs cover up the display. The fingernail display aids in reading tiny text because it can enlarge an area of the screen as you move your thumb over it. The technology also could create screens for devices that do not have one, such as the iPod Shuffle.
The technology includes an accelerometer, which will enable different content to be displayed using different finger gestures.
