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.
