Abstract
In one example an electronic device comprises a proximity detector, a camera, and a controller, comprising logic, at least partly including hardware logic, to receive, from the proximity sensor, an indication that an object approaching the electronic device is within a predetermined distance while the electronic device is in a first low-power state, and in response to the indication, to activate the camera on the electronic device while the electronic device remains in a low-power state and determine whether an image input to the camera is a human while the electronic device remains in a low-power state. Other examples may be described.
