Apple has won a patent for a high tactility glove that would enable use of the iPhone's touchscreen in cold weather, according to Patently Apple.
The inner liner may be manufactured from any suitable material, including materials with properties similar to human skin. For example, the inner liner may be manufactured from a material that has a low thermal conductivity, electrical resistivity similar to human skin, "anti-sticky" attributes, or any other suitable property. In some embodiments, the material for the liner, the outer shell, or both may be selected to closely mimic the tactile effect of manipulating the electronic device using bare fingertips. ... In some embodiments, the outer shell may include a mechanism by which the liner may protrude through the outer shell to allow a user to operate an electronic device. For example, the outer shell may include one or more apertures operative to allow the liner to pass through. The apertures may be located on any suitable portion of the outer shell, including for example on the finger tips, or along the finger.
