In the past few months, we have covered plenty of interesting wearable technologies. NailO, developed at the MIT Media Lab, happens to be a wireless trackpad that sits on your thumbnail, allowing you to interact with smart devices and digital interfaces. You will be able to use it to browse websites, switch between symbol sets, or communicate with others in a discreet fashion.
The above video shows NailO in action. The challenge for the researchers was to fit sensors and chips in a space no longer than a thumbnail. When will we see people walking around with digital fingernails? That is anybody’s guess at this point.
