Emil Protalinski, The Next Web:
Google appears to be planning an interesting set of gestures for its Glass project, letting you use your fingers, head, and eyes to perform certain functions. Two examples include being able to use two fingers to zoom in and out of the browser, apparently just like on a touch device, as well as winking to take a photo.
Winking to take a photo with a device that’s so subtle as to not be noticed, and have that photo automatically upload? Now that’s creepy.
