Wink

For those times you might miss a shot, try capturing the moment with a wink. The Wink feature is an exploratory feature that lets you take a picture with a wink. It's even faster than the camera button or voice action and it even works when the display is off.

To turn it on and calibrate it for the first time:

1. Swipe backward from the Home screen until you see Settings.
2. Tap Settings and swipe forward to the Wink settings card.
3. Tap the Wink card to calibrate Wink for the first time.

You'll be asked to wink twice to calibrate Wink. For consistency, it helps to look at the screen when winking.

Etiquette

Use your best judgment when using Wink. Be careful who you're winking at and be conscious of your surroundings when you do it. You don't want to give off the wrong impression. ;-)

How it works

Right next to the display is a tiny light sensor that watches your eyelid move. It's used for on-head and wink detection. If the sensor is obstructed or aimed incorrectly, these features will not work.

In case you're wondering, this light sensor is completely safe. The light it emits is no more dangerous than natural light.

Troubleshooting Wink

Wink on older devices

Wink only works on the latest version of Glass devices. Devices received before October 28th, 2013 won't show the Wink feature in the Settings bundle. If you want to take part in Wink and other future features and accessories, sign up for our limited-time swap out offer.

Wink doesn't work on everyone yet, but here are some things to try if Wink isn't working properly.

For best results, look at or through the screen when you wink. This may involve tilting your head up or down slightly to be able to see through the display.

Make a calculated and deliberate wink. The wink sensor may not pick up a fast wink. For best results, make a mental effort to scrunch the corner of your eye and try to time your wink to a half second.

Glass's fit can sometimes position the camera differently, depending on your unique facial features. The wink sensor needs to be properly aligned in order to work correctly. In most cases this means having Glass just above your field of vision, and adjusting the display so that you can see the entire screen. For more tips, visit this this article on fitting Glass.

It doesn't matter what time of day you use Wink, but sometimes Wink will need to be recalibrated if you're squinting in full sun or, conversely, if your eyes are at rest in the dark. If you can't get wink to work in a certain environmental condition, try recalibrating on the spot.

Some eye makeup might throw off the Wink sensor. To fix, recalibrate Wink after you've applied your makeup.

If you calibrated Glass with shades or shields installed, try taking them off and trying again. If you don't think you'll need shades or shields for a while, recalibrate without them.

Recalibrating Wink will solve most issues, but we're aware that Wink won't work with every face. If you're not satisfied with Wink's performance, turn it off from the Wink card in the Settings bundle.
