Abstract

A conferencing system and method detects one or more two-dimensional (2D) images in presented 2D data and/or objects shown during a videoconference and renders them on a participant's three-dimensional (3D) tactile screen. The system includes a conferencing server that is in communication with one or more participant devices. An image recognition engine is in communication with the conferencing server and identifies the one or more 2D images. An imaging processor is in communication with the image recognition engine, and may be in communication with a camera that recognizes objects shown during the videoconference. The imaging processor creates a 3D rendering of the 2D images and/or the objects and directly or indirectly sends them to the participant's 3D tactile screen.
