The readers are assumed to be familiar with names of basic Windows 8 touch gestures (for which, see http://windows.microsoft.com/en-us/windows-8/touch-swipe-tap-beyond )
With some Windows 8 tablets (or laptops), you may come across a sudden appearance of the Camera app or the sudden activation of the webcam when you are trying to turn on your laptop (or maybe more precisely, when you are trying to sign in to your PC from the lock screen).

2. how to get out
It is actually quite simple to turn off or deactivate this thing. You simply tap or click Unlock which should be found on the left side of the app commands at the bottom of the screen and you are back to the lock screen.
3. how did I end up there
You usually swipe up on the lock screen to sign in to your PC, but when you swipe down on it instead, that launches the Camera app. This is a useful feature of Windows 8 that you can turn on or off. The Camera app launched in this way seems to show a different interface from the one launched in the usual way. Maybe it is not the same Camera app? I am not sure.

Swipe down on the lock screen to use the camera
