  • Patent number: 11982926
    Abstract: A method is disclosed for eliminating potential video echo effect for a collaboration session that utilizes AR environments. During the collaboration session and in the local AR environment, a contact overlap mask is generated that identifies a content overlap region where the projected remote content superimposes over the physical object placed on the local workspace surface. Based on the contact overlap mask, the local AR environment is temporarily modified throughout a short time period when the projected remote content is prevented from superimposing over the physical object within the content overlap region. A local image is generated based on the temporarily modified local AR environment and sent to the remote workstation for sharing in the collaboration session. By excluding any projected remote content from superimposing over the physical object in the local image, a potential video feedback loop is eliminated so as to eliminate any potential video echo effect.
