+prevent the system from sleeping when a user is looking at the screen.
+
+this is accomplished using the built-in camera on my laptop screen's top bezel
+and opencv to detect a face.  i'm going to use the API used by the default movie
+player in ubuntu for preventing system sleeps.
+
+OTHER IDEAS:
+1. detecting a face could simulate user activity.  this would prevent sleeping
+and bring up the password prompt when the system is already asleep.
+       * how cool would that be?  if the system is asleep and you sit down at it, the
+       password prompt comes up before you touch anything!
+       * or if the screen saver doesn't lock the screen, then the laptop just wakes
+       up.
+2. authenticating a user based on face recognition (as opposed to face
+detection)
+       * much more difficult to do reliably
+3. be more aggressive with turning off the screen.  dim the screen as soon as
+it's not being looked at.  turn it off soon thereafter.
+       * could be enough to save battery.  would need to power the camera sometimes,
+       but would save on backlight.  need to test.
+4. don't prevent sleep when face is detected, but user isn't actually looking at
+screen.
+       * requires pose estimation.
+       * also requires estimating the direction of the eye.
