Gaze-tracking-based image downscaling for multi-party video communication

One or more tangible, non-transitory, machine-readable media storing instructions that, when executed by one or more processors, effectuate operations comprising:

• receiving a first set of screen positions from a first receiving computing device and a second set of screen positions from a second receiving computing device during concurrent video communication sessions between the first and second receiving computing devices and a presenting computing device;
• predicting a shared position based on the first set of screen positions and the second set of screen positions;
• generating a downscaled encoding of a source image from the presenting computing device by downscaling the source image at a set of regions of the source image, wherein the set of regions does not comprise the shared position;
• and
• sending the downscaled encoding to the first receiving computing device and the second receiving computing device.

A system comprising:

• one or more processors;
• and
• memory storing computer program instructions that, when executed by the one or more processors, cause the one or more processors to effectuate operations comprising:
• obtaining a first set of screen positions associated with a first receiving computing device and a second set of screen positions associated with a second receiving computing device during concurrent video communication sessions between a presenting computing device and the first and second receiving computing devices;
• predicting a shared position based on the first set of screen positions and the second set of screen positions;
• downscaling a source image from the presenting computing device at a set of regions of the source image to generate a downscaled encoding, wherein the set of regions does not comprise the shared position;
• and
• sending the downscaled encoding to the first receiving computing device and the second receiving computing device.
