Carnegie Mellon University researchers developed a system that turns your arm into a trackpad. Video demo above. From their scientific paper:
It consists of a ring, which emits a continuous high frequency AC signal, and a sensing wristband with multiple electrodes. Due to the phase delay inherent in a high-frequency AC signal propagating through the body, a phase difference can be observed between pairs of electrodes. SkinTrack measures these phase differences to compute a 2D finger touch coordinate.

The Certified Ethical Hacker Bootcamp […]
The human eye is a powerful thing, but it’s not so great at seeing in the dark or around tight spaces, which is partially why most of us struggle with unplugging drains, cleaning under the fridge, and other hard-to-reach jobs.
