Collaborative, social online education and whiteboard techniques

摘要

Various techniques are disclosed for facilitating a computer-supported collaborative session that includes at least two participants using different computing devices to view a canvas that is configured to contain objects added by one or more of the participants. The computer-supported collaborative session is configured to permit participants to mark and/or edit selected objects presented on the canvas. Participants may use a mobile device camera to capture images or video clips, and post the captured images or video clips to the canvas by emailing or text messaging the captured image to a designated email address or phone number.
