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.
+this is accomplished using a camera and opencv to detect a face.
-OTHER IDEAS:
-* 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.
- * DONE!
-* fire up the face detector only just before going to inactive mode.
- * that way the camera isn't running all the time
- * maybe start 10 seconds before going inactive, then run until activity
-* authenticating a user based on face recognition (as opposed to face
-detection)
- * much more difficult to do reliably
-* 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.
-* 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.
+this readme is woefully short.
