Modern presentation software is still built around interaction metaphors adapted from traditional slide projectors. We provide an analysis of the problems in this application genre that presentation authors face and present FLY, a presentation tool that is based on the idea of planar information structures. Inspired by the natural human thought processes of data chunking, association, and spatial memory, FLY explores authoring of presentation documents.Evaluation of a paper prototype showed that the planar UI is easily grasped by users, and leads to presentations more closely resembling the information structure of the original content, thus providing better authoring support than the slide metaphor. Our software prototype confirmed these results, and outperformed PowerPoint in a second study for tasks such as prototyping presentations and generating meaningful overviews. Users reported that this interface helped them better to express their concepts, and expressed significant preference for FLY over the traditional slide model.
RELATED WORKPrevious projects that aimed to improve the slideware user interface are mainly based on a combination of different technologies and interaction concepts. These range from pen interaction, physical interaction, and path mechanisms to graph layouts and zoomable user interfaces:
Pen InteractionClassroom Presenter [1] allows for versatile writing of annotations onto and next to slides, and for anonymous feedback from the audience. Pens have also been employed for flexible authoring of informal presentations [12], or together with speech input [20]. Major advantages of pen interaction are easy prototyping and rearranging, as well as impromptu additions during presentations [19].Physical Interaction
