Apple was recently awarded a patent for gloves that can be used with the capacitive touchscreens found in the iPad, iPhone, iPod touch, and iPod nano. Because those screens react to the change in electrical current created by skin touching them, gloves can get in the way.
Apple’s solution has two layers, an outer protective one and an inner conductive one. The wearer pulls the outer layer back to allow the inner one to peek through a small hole, enabling touchscreen use. Of course, as Cult of Mac notes, gloves that work with capacitive touchscreens already exist.

Patently Apple has more details about the patent.
