Patent ID: 10609333

Abstract:
In the present invention the camera of a student's mobile communications device sends a live image of the student's paper through an image-sharing subsystem to the instructor's personal computing or mobile communications device. An annotation subsystem allows the instructor to mark said image of the student's paper, and a background-subtraction subsystem allows a background-free image of the instructor to appear on said image of the student's paper. A screen-sharing subsystem transmits a combined image of the student's paper and the instructor and his or her markings back to the student's device. Mounting the student's device above the paper on which he or she is working allows the student to see the instructor and the instructor's markings overlaid on the student's paper, giving the impression that the instructor is present and collaborating on the student's work. Videoconferencing and communication-management subsystems facilitate communication between the instructor and the student(s) during this collaboration.
