Should I Sleep for Mac

From Mr. Milk:

Annoyed by the display getting dim when you're reading or watching something? By using a combination of heuristic sensors, such as face detection, Should I Sleep checks if you are actually at the computer before it sleeps. When the display is about to dim, Should I Sleep will start its sensors. Camera, microphone all other software processing will stay on for only about 3 seconds. After that, sleep will be allowed or prevented. No need to touch any button. Face detection is the most effective sensor and works by capturing video from the camera and looking for eyes, nose and mouth. If one or more faces are detected, sleep is prevented. Sleep is prevented if a moving target is captured by the camera (such as waving, walking or even slightly moving your head). It works even when you are not directly facing the camera. Prevent sleep if there is network traffic. It works with all apps, on operations such as downloads and uploads, enjoying online videos and music and also receiving emails. And it even lets you keep downloads with the display dimmed. Prevent sleep if any app is performing CPU intensive tasks, such as audio and video conversions, encodings, renderings, scientific calculations, image processing, etc. Prevent sleep if an external display is plugged-in. A must-have for those who give presentations, speeches, demonstrations and/or trainings. That's the sensor that will "hear" you. It prevents sleep If ambient sound is detected. Useful when you're talking near the computer such as in workshops and meetings where the camera may not be in a favorable position. We have also added the old-style timed sleep prevention (caffeine mode). You just choose a predefined time period for the computer to be kept awake.
