NailO Is a Tiny Trackpad for Your Nail to Navigate Devices

In the ever changing world of technology, several companies have been experimenting with new ways to navigate our devices, notably with eye-tracking technology dubbed the next big thing. Wearable technology is also making a splash in the form of watches. However, a team of MIT researchers have merged the two and are testing something of a smaller scale — a tiny trackpad for your thumbnail called NailO. The project was inspired by nail stickers that are popular in Asia, and the idea of being able to navigate your device while having both hands full. The prototype incorporates a swappable membrane so you can change its design whenever you’d like, while the team is still improving the design with a 0.5mm battery and a multipurpose chip that functions as a micro controller, a radio, and a capacitive sensor.
