This is my brother Brian, who I saw over Thanksgiving. And this is his glove - which has been made conveniently smartphone-friendly by his dog, Wally, chewing through one of the glove's fingertips. Almost all modern smartphones use capacitive touchscreens, which are great for light-touch dragging and multitouch gestures but which don't respond to gloved fingers. Sure, there are phone-friendly gloves for sale out there, which include special capacitive-triggering materials in the tips or simple chopped tips just like this (but intentional). But hey, why buy those when man's best friend can do the job for ya?
