Annotation and whiteboard tools can be used in a classic way with an interactive projector / whiteboard or large format touch screen.
However, the Presenter and the Multi-user scenario additionally offer all the agility, interactivity and collaboration functionality.
All annotation tools are also accessible on a mobile device / tablet. The presenter is not tied up to the main screen anymore. He still has full control on his host device with all types of application software.
In addition to the presenter also the participants are logged into the session. This unlocks all possibilities for sharing, annotating, collaborating and voting.
