Fly: a Tool to Author Planar Presentations
- We presented two studies on Canvas Presentations at CHI 2012
- Christian Corsten presented DragonFly, an extension to Fly for reviewing lectures, at CHI 2010.
- Fly in the press.
IntroductionNowadays we come across presentations quite often. Either we attend a talk at a conference or we give a presentation to explain our recent research project to others. To give a presentation is a demanding task, as it often takes many days to research, structure, plan, and rehearse the talk. Mostly, we use slides to visualize our ideas and concepts and to help the audience to understand. While creating slides, authors might have some problems due to limitations of the slide metaphor. Slides separate content into discrete chunks of equal size, but it might be difficult to divide information according to the slides’ size. Another problem is, that current presentation software, like Microsoft’s ’’PowerPoint’’ or Apple’s ‘’Keynote’’ force a linear timeline (one slide after the other) and thus restrict the presentation of information to a predefined sequence.
Fly is a prototype presentation system for authoring presentations that uses a different approach. It is based on the idea of planar information structures. Fly is however, not based on the slide metaphor but allows authors to freely lay out information on a plane in a map-like fashion. The system aims at making the authoring process more fluid and less constraining.
The TeamFly is a research project by Thorsten Karrer, Leonhard Lichtschlag, David Holman, Jan Borchers and others at the Media Computing Group. It is funded in part through the German B-IT Foundation and the UMIC DFG Excellence Initiative.
TechnologyFly was inspired by the natural human thought processes of data chunking, association, and spatial memory. The author is not restricted to the size of a slide, but can freely arrange information chunks (text, photos, graphics etc.) on an infinite plane like a collage. This spatial organization of the content makes it easier to visualize a meaningful overview of the information.
Fly supports two views of the content: a high level view shows a semantic abstraction and its context, whereas a near view goes into more detail, similar to the difference between a country and city map.
The author can create a path through the material of his presentation. He simply sets up a certain view of the plane and presses a snapshot button. The sequence of snapshots (stops) defines the route, which is followed during presentation. Transitions from one section of the plane to another are always continuous, and they are always meaningful due to the layout of the plane itself. Fly provides a smooth “flight” over the presentation material, using camera zooming and panning. When reaching a path stop Fly zooms in on the content, showing details. To move on, Fly zooms out again, showing the overall structure and goes on to the next path stop.
2009 Authoring Lab StudyEvaluation 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.
2012 Audience Lab StudyEvaluation of Canvas presentations in a classroom setting indicates that canvas and slide deck presentations are equally capable of conveying information to an audience, even for students with lower spatial ability. Our study is fully replicable, all materials can be downloaded here.
2012 Authoring Field StudyWe confirmed and expanded our results of the 2009 study by investigating real world canvas presentations.
DownloadYou can download the DMG file here and play around with it (Mac OS X 10.5). It is still a prototype and should be treated as such, do not use it for production. Tell me (Leonhard) what you like and what you don't like. Tell me about bugs, crashes and problems.
