We have seen plenty of interesting touch-enabled gadgets in the past couple of years. NailO happens to be a new wearable device that turns your thumbnail into a wireless trackpad. Developed by the MIT Media Lab, NailO can be used to control digital devices or interact with digital interfaces. For instance, you can use it to toggle between symbol sets, send a quick text in a subtle fashion, or answer calls while cooking.
The researchers behind NailO will be presenting it at the Association for Computing Machinery’s Computer-Human Interaction conference in Seoul, South Korea next week.
