This app can pause games and videos when you're not looking at the screen
Samsung has long had a Smart Stay feature that keeps your screen on while you're looking at the screen, while Google seems to be implementing something similar in Android Q. This app, on the other hand, introduces a twist on the same basic premise that can be equally as convenient.
Face Pause is still in its early stages of development, so it's not the most stable app out there, but it serves as a nice proof-of-concept for a very simple, yet overlooked, user experience improvement. As the name suggests, the app allows you to pause a game or video playback by simply looking away from the screen. It was developed by XDA member CarlDuncan and is currently live on the Google Play Store, if you'd like to try it out.
One of the biggest shortcomings of Face Pause currently, is the fact that it has some problems with YouTube, which is what we really wanted to test it on. That's why the developer has also released Face Tube – a modified version of the app that works a bit better with Google's ubiquitous video sharing platform, but is still rough around the edges.
Again, this app is still in its very early stages of development, so don't expect a perfectly polished product. However, if you're interested in testing out a creative implementation of face detection, you can try it out right now. We'd be willing to bet that more apps—even Android itself—will start doing this in the future.
