MIT researchers have developed a very small wireless track pad, which resembles a fake fingernail. The idea of the gadget is to make it possible for users to control their devices when they are at their most busy.

The device is a very small touch panel attached to a thumbnail and is controlled by a forefinger of the same hand. This wireless track pad can be useful for people who are cooking or repairing something. Indeed, such a device gives them an opportunity to turn the page of a recipe book or to turn on music without any breaks in the work.

The prototype has been developed by MIT (Massachusetts Institute of Technology) Media Laboratory researchers.

When it comes to size and mass, NailO is similar to a quarter coin: 24.3 millimeters in diameter and weighing 5.7 grams. The device includes a mini battery, a microcontroller, a Bluetooth radio chip for wireless communication, capacity sensor and a decorative lop layer… see more
