A few months after adding background blurring to its Teams tool, Microsoft has brought the same option to Skype on the desktop. From a report: The feature serves two purposes. Firstly it helps to focus attention on the person that is speaking, but secondly — and perhaps more importantly — it hides any untidiness (or secrets) that may be going on behind the speaker. It’s another push from Microsoft to move people away from Skype Classic to Skype 8. Background blurring makes use of artificial intelligence to pick out the subject of a video, having been trained to detect hair, hands and arms.
