Abstract: Examples of electronic devices are described herein. In some examples, an electronic device includes a camera. In some examples, the electronic device also includes a processor to start a lock timer to lock the electronic device in response to detecting that a first person leaves a field of view of the camera. The processor is also to adjust the lock timer in response to detecting a second person within the field of view of the camera.

Abstract: In one example in accordance with the disclosure, a computing device is described. An example computing device includes a gaze tracking device. An example gaze tracking device identifies, from a captured image, a gaze region for a user viewing a display device coupled to the example computing device. The gaze region indicates a location on the display device where the user is looking. The example computing device includes a controller. An example controller determines a first window on the display device that is aligned with the gaze region and based on a determination that the first window is aligned with the gaze region, adjusts a video setting of a second window that is outside the gaze region.

Abstract: In some examples, an electronic device includes an image sensor to capture an image of a scene. In some examples, the electronic device includes a machine learning circuit to execute a machine learning model on the image of the scene to determine a shutter activation parameter. In some examples, the machine learning circuit is to activate a shutter of the image sensor in response to determining that the shutter activation parameter satisfies a condition.

Abstract: Examples disclosed herein provide a computing device. As an example, the computing device includes a camera comprising a lens, and a housing comprising an opening extending through the housing, wherein the opening is to accommodate the lens. The housing further includes a shutter to selectively obscure the opening, and a mechanical trigger, upon receiving an electrical signal, to move the shutter to obscure the opening.

Abstract: In one example in accordance with the present disclosure, an attention analysis system is described. The attention analysis system includes a database. The database includes 1) images indicative that users are paying attention to corresponding computing devices and 2) images indicative that users are not paying attention to corresponding computing devices. The system also includes an analyzer to extract multiple user position characteristics from a stream of images of a user disposed in front of a computing device. A comparer of the system determines, by comparing the stream of images of the user to the images in the database, whether the user is paying attention to the computing device.
