The prototype offers visualising and navigating the slides as well as “pointing” and zooming. In this project, a prototype application was implemented for the iPad in order to explore, develop, and test the concept of pointing in remote presentations. have shown that the mouse cursor and laser pointer offer very little informational expressiveness and do not do justice to human communicative gestures. The traditional “pointing feature” present in some presentation tools comes as a virtual laser pointer or mouse cursor. Keynote, PowerPoint, FuzeMeeting and others support placing-for efficiently with slide transitions, and animations, but support limited to none directing-to.

"This thesis argues on the possibility of supporting deictic gestures through handheld multi-touch devices in remote presentation scenarios.
