All hands are on deck over at MIT where a very handy new trackpad has been created that will be able to give users a free hand to do other tasks. The device is called the NailO and attaches to one’s thumbnail, which allows the user an easy and reportedly natural way to use a trackpad while your hands are full, dirty, or otherwise occupied.
The device reportedly works like any normal trackpad, but is about the size of a quarter and attaches to the thumbnail in such a way that it takes advantage of the natural motion of running an index finger over the thumbnail. It communicates via Bluetooth radio, and has four layers which all go hand-in-hand: an artistic covering (to replicate the look of a painted fingernail), the sensors, the circuitry, the battery, and presumably an adhesive of some sort.
Details are quite sparse, but the device is scheduled to make its debut at the Computer Human Interaction conference in Seoul, South Korea very soon. If it can be made less bulky (although it’s somewhat uncomfortable to call something smaller than a quarter “bulky”) this might be, hands down, the next greatest evolution in mouse technology since multi-touch. We have to hand it to MIT for coming up with such a unique wearable!
