The odds are you can't make out the PIN of that guy with the sun glaring obliquely off his iPad's screen across the coffee shop. But if he's wearing Google Glass or a smartwatch, he probably can see yours.
Researchers at the University of Massachusetts Lowell found they could use video from wearables like Google Glass and the Samsung smartwatch to surreptitiously pick up four-digit PIN codes typed onto an iPad from almost 10 feet away-and from nearly 150 feet with a high-def camcorder. Their software, which used a custom-coded video recognition algorithm that tracks the shadows from finger taps, could spot the codes even when the video didn't capture any images on the target devices' displays.

A problem I see with the random digit keypads (as proposed earlier) is that it will take you a longer time typing in the number, and maybe exposing more clearly what you type in because you have to look at the keypad. Now I just wave my hand over the keypad, using the other hand as a shield. I still like the idea though.
