Yawls stands for Yet Another Webcam Light Sensor,
it is a small Java program created for Ubuntu, it adjust the brightness
level of your display by using the internal/externel webcam of your
notebook as an ambient light sensor, that uses the OpenCV Library and
designed to comfort and save energy of your laptop battery. Yawls can
also be used from command line interface and run itself as a system
daemon, two times a minute it runs and adjusts the brightness of the
notebook screen with reference to the ambient brightness. It doesn't
engage webcam constantly, as mentioned above in a 30 seconds interval it
uses the webcam and leave it for other programs to use. The interval
time can be adjust from GUI or from config file if you are using CLI
version
It also has face
detection option which can be useful if you sits in dark room and yawls
can adjust screens brightness as per your needs, by default this option
is disabled, you can enable if you intend to use it. After very first
installation you must calibrate yawls otherwise it may not function
properly. If it causes problem somewhere between usage then re-calibrate
it. If you found any kind of bug in the application then report it via github or launchpad.
