Post updated on March 20, 2020 with information about blurring support in the Teams for iOS client.
Blurring Hardware for Modern PCs
Announced in July 2018 along with the free version of Teams, users can blur the background of video calls. The feature is now generally available. However, the technology to perform face recognition to identify the person and understand where the background to be blurred begins and ends only runs on reasonably recent PC equipped with Advanced Vector Extension 2 (AVX2) graphics. AVX2 is what Teams uses to blur the background after it figures out where the user is.
AVX2 is supported by PCs that have a post-Haswell chipset. Blurring works on my Surface Book 2, but doesn’t on my HP Envy 17 of 2014 vintage. Be aware that the CPU has some processing to do to locate a face and blur the background, so it can impact other work on the PC if you run a loaded system.
Blurring Your Background
To blur your background during a video call, select the Start video with blur option when you join a call or the Blur my background option from the […] meeting menu. If things go blurry, you know that your PC can do the business. If not, maybe it’s time for an upgrade if you think that blurring is a big business feature that justifies the expenditure.
To turn background blur off, select the Don’t blur background option from the […] meeting menu.
Background Blur in Teams for iOS
Previously, background blur only works in the Teams desktop client. It’s not available in the browser client. Microsoft is currently preparing for widespread deployment of background blur for the Teams mobile client for iOS. This feature has appeared on my iPhone. You can join a meeting with blur enabled (Figure 1) or enable blurring during the meeting from the call menu. Note the small blur icon in the upper left-hand corner which controls turning blurring on or off.
Blur the Meeting
Blurring backgrounds is a nice feature, but sometimes I feel that it would be even better if I could blur some meeting attendees. But I’m grumpy at the best of times, so there’s no surprise there.
