Tiny Screens For Fingernails Provide Easy-To-See Interactive Display
The 'NailDisplay' prototype can extend your device's screen so your finger doesn't block what you're viewing.
A team from the National Taiwan University in Taipei have developed a prototype device that turns your fingernail into a display. ‘NailDisplay‘ offers an always-available nail-mounted display that provides visual feedback on a 96×64 OLED screen.
In a research paper, the team wrote about three applications for this device. Firstly, it could be used to reveal or enlarge an area of your touchscreen or tablet that is obscured by your finger. This would make it easier to operate small user-interface elements or read small text, as it enables you to see what is beneath your finger.
Another application could be providing a display for a device that usually doesn’t offer one, like a music player (iPod shuffle), so you can view different elements at the same time.
Also, it could be integrated with finger interactions using an accelerometer, so it would respond to gestures such as swiping in the air. The Verge notes that in the future the team sees this technology being used with flexible displays that fit over your nails like polish. Check out the video below to see the prototype in action:
