The YouSeeU-VC (Virtual Classroom) app allows a mobile IOS user to join a YouSeeU Virtual Classroom (or Sync Meeting), as a viewer, and participant. The mobile user will have full audio and video capabilities with the built in camera. They will also be able to use features like chat (private and public), view all participants in the meeting, view the deskshare, and whiteboard with all drawing annotations, as presented by the moderator of the meeting. As a mobile user, they will not be allowed to become a presenter in the meeting, and can not run or create meetings. The meeting must be started by a web client using the HTML5 interface before a mobile user will be allowed to join.
