Current video conferencing technology relies on sending a video stream to a flat, single layer screen, with no depth perception possible, as the image is fixed regardless of viewing angle. This reality results a compromised experience compared to what should be possible with modern day technology. Presented herein are novel techniques through which existing technologies can be applied in order to separate a participant (in the foreground) from a known state of an unchanging background, and then introduce a parallax effect using face tracking of the observer to control the angle of parallax, thus, adding a three-dimensional (3D) effect to an otherwise two-dimensional (2D) video, thereby providing a more engaging and lifelike user experience.
