Traditionally, the only way employees could survive was to reduce their metabolism until they reached a hibernation state. These days, many companies direct their serfs to a webpage that hosts all the videos and slideshows on it for you to review at their leisure. And by "review at their leisure," we mean they can start the video and then go take a dump and play that game Kate Upton's boobs are selling.
Some companies, however, wised up to how much we hate watching local actors make terrible puns about the office dress code, and are now putting their employees in the digital equivalent of a Clockwork Orange chair. A feature on many phones and tablets now is "eye tracking," which utilizes the device's camera to figure out where you're looking, and can do things like scroll web pages. Alternatively, if you're the type of boss who hates happiness, you can use it to pause training videos when employees look away from the screen.
"Excuse me. My soulless, ever-watching digital eye is up here."
A group of Stanford students got together and developed this "smart pause" feature, and have been marketing it to companies so that they could make sure that employees were actually watching their training videos and not f*****g around on comedy websites instead. Mindflash, the company that markets this technology, claims that in addition to acting like a teacher who can "wait here all day," companies can use it to identify where the boring parts are and try to spruce them up so that watching training videos is less of a Sisyphean task.
