Touchscreens are everywhere these days, and even though you've probably heard people mumble about the relative benefits of capacative screens compared to resistive ones, you might not actually know how they work. This video explains.

Greg Foot describes how reisistive screens work, before explaining how Apple swung the market in the other direction, to favoring capacotive screens instead. That's what the bulk of the video's really about: from the simple business of registering a single touch, through recognising complex gestures, and the implications of more recent advanced like in-cell screen technology. It's a great little introduction to how touch screens works; well worth watching. [Head Squeeze]
