There have been a lot of convenient options when it comes to Netflix’s streaming service, but thanks to the introduction of some new footwear from the company, the convenience just went a little bit further.

The streaming channel has partnered up with Pittsburgh-agency Deeplocal to introduce an innovative idea that works with its service in the form of a pair of socks, according to AdWeek. Not only are they sure to be comfortable, but they can detect when the viewer falls asleep, and automatically pause whatever program they’re watching. 

How these socks work is explained below, as posted on Netflix’s “Make It” website. (Yes, customers have to make the socks.)

We’ve based our sleep detection system on a popular method called actigraphy. An accelerometer detects when you’ve stopped moving for a prolonged period of time and triggers a signal to your TV that pauses Netflix. When it detects that you’ve dozed off, an LED light in the cuff of the sock flashes red, warning that the pause signal is about to be sent to your TV. Any motion will stop it from firing.

The accelerometer is very sensitive to little movements, so it’s good at detecting when you’re just sitting still, raptly watching Netflix, and when you’ve actually fallen asleep.

Full instructions on how to make the socks can be found on its official page. It does require a bit of handiwork, but Netflix explains that “if knitting isn’t your thing, you can always enlist the help of a knitting-savvy friend.” It also advises that “to build the sensor, you’ll need an understanding of electronics and microcontroller programming, and be comfortable around a soldering iron.”

It feels like a bit of a missed opportunity that Netflix isn’t making the socks themselves, but considering the hard work it’s already putting into its programming (like the Marvel show deal, the forthcoming Fuller House series and the forthcoming premiere of its first original movie, Crouching Tiger, Hidden Dragon: Sword of Destiny), it’s easily forgivable. 2016 looks to be even better, with the promise of over 30 original programs.

On the bright side, it sure beats an ugly Netflix Christmas sweater, right
