Smartwatches walk a fine line between functionality and fashion, but new SkinTrack technology from Carnegie Mellon University's Future Interfaces Group makes the size of the screen a moot point. The SkinTrack system consists of a ring that emits a continuous high-frequency AC signal and a sensing wristband that goes under the watch. The wristband tracks the finger wearing the ring and senses whether the digit is hovering or actually making contact with your arm or hand, turning your skin into an extension of the touchscreen.

The tech is so precise that you're able to use the back of your hand to dial a phone number, draw letters for navigation shortcuts, scroll through apps, play Angry Birds or select an item from a list. Researchers at the Future Interfaces Group say the tech is 99 percent accurate when it comes to touch.

"As our approach is compact, non-invasive, low-cost and low-powered, we envision the technology being integrated into future smartwatches, supporting rich touch interactions beyond the confines of the small touchscreen," the creators write in a YouTube description.

This isn't the first iteration of touch-skin technology, but it's by far the most stylish and streamlined. We can already imagine the customizable "Apple Watch + SkinTrack ring" bundles.
