Google AI knows when a stranger is looking at your phone


Have you ever had the feeling that someone is looking over your shoulder at your phone? Well, you may not have to worry about that in the future: Google researchers have developed an AI tool that can detect when someone takes a look at your screen.

The software – which was first discovered by Quartz – is called "electronic screen saver" and is currently in the research stage. (We do not know if Google plans to add it to future versions of Android, but we have approached to verify it). It's quite simple: use the front camera in combination with face detection and look Algorithms to identify anyone who looks at your screen.

In the demo video, above, you can see him react almost instantaneously to a suspicious looky-loos, changing the user's screen to catch the guilty one with the red face, and labeling them with some Snapchat-type rainbow vomit for a good effect. According to Quartz the creators of the electronic screen saver, Google researchers Hee Jung Ryu and Florian Schroff, say that the system works in all kinds of different lighting conditions, and has a reaction time of only two milliseconds With that speed, you're even likely to catch a glimpse!

Although we can not say whether Google will ever bring this feature to Android, it is a perfect example of the kind of small software settings that AI can offer for mobile devices. Google is doing more and more machine learning on the device with the help of its TensorFlow Lite software, and has added simple tools that automatically detect numbers and addresses when copying and pasting text, and suggests quick responses to their emails, for example.

Features like this may seem trivial in isolation, but collectively they will add up much more. Machine learning and AI are already becoming the big differentiators among smartphones, so we hope to see more in the near future.
