Share your Whiteboard Screen on Learner iPads/Androids with TeamViewer.
Basically a practitioner installs the free TeamViewer client on their computer and starts a meeting. Learners runs the free TeamViewer for Meeting app on their iPad/Android and then enters the meeting room code the Practitioner gives them. They can see the computer screen, and zoom and pan around it. But importantly, not interfere with what the practitioner is doing.
Great potential for WBL learners etc.
