Join Doug Winnie for an in-depth discussion in this video Can I tell if someone is taking a photo or video of me using Glass?, part of Google Glass First Look.
If you see someone and you're wondering if they're taking a picture of you, there are few ways you can tell. Right here is the camera button. If someone is wearing Glass and they push on this button, that means that they currently actively taking your picture. Now, in addition, just so with any other functions of Glass, you can control most actions using your voice. In this case if I say, okay Glass, take a picture, it will then use the camera here to take a picture of whatever is in front of them. In addition, all functions that you can activate with your voice you can also activate with the menu commands that are located here on the right.
So they can slide to picture, tap it a couple of times to take a picture. Now, there's a fourth way. And this is one of those experimental features that's part of Glass. It's not turned on all the time. But users can actually turn this option on, if they want to. You'll see right here there's a small camera. Now, this camera isn't used for taking pictures. What this camera can do, though, is it can actually detect your eye. With this experimental feature on, if I wink my eye it will sense that and then take the picture. Now generally whenever you're having a photograph taken you'll hear a Or a little bit of a click sound coming from the speaker inside of the, inside of the Glass.
But there is no actual flash or any kind of red light that shows that the photograph's been taken. Now filming is also done the same exact way. Instead of just pressing on the button once, if I push and hold it, that's means I'm filming somebody. It's not just a single picture, it's actually creating a movie. Unlike a camcorder or any type of mobile device that might have a red light that's showing that it's currently recording There is no light here. So, just like with an iPhone or an Android phone, if you're recording a video, there's no indicator that that actually is happening. Again, the only ways you can tell are, if they're touching the button, or if you actually hear them activate, take a picture, or take a video.
