Most modern Unified Communication solutions are able to hide the background behind the person that sits in front of the webcam. Typically, the background is blurred out, or replaced with an image or a video.
For those Unified Communication apps that do not support this feature, at least not in a VDI context, IGEL OS provides a universal virtual background that can be used by any Unified Communication solution. This is achieved by creating a virtual webcam; within this virtual webcam, the virtual background is mixed with the video input from the real webcam. The video stream from the virtual webcam is then fed to the Unified Communication client.
