The Thumbnail Trackpad You’ve Been Waiting For Is Finally Here

Apr 17, 2015 at 12:04 PM ET

The rapidly expanding world of wearable technology has given us computer glasses and Dick Tracy watches, but the next big thing might just be a press-on fingernail. MIT has created a device that allows a person to control any wireless device simply by touching their thumbnail. It’s essentially a laptop mousepad unobtrusively located on your thumb.

If the NailO works as promised, the device would allow users to answer the phone while carrying groceries or draw a picture on their tablet computer from 10 feet away. The possibilities are kind of endless. While the video (see below) looks quite impressive, plenty of questions remain: Will men wear feel weird about wearing press-on thumbnails? What about washing your hands? And, most importantly, will it function properly? While MIT undoubtedly knows what it is doing, we mustn’t forget the “Worst Product Ever Made” is not even a year old (see second video below).
