Hello,

First I want to say THANK YOU for sharing such a wonderful program. I almost was in the process of programming a presentation program for myself, which would allow me to start from brainstorming, building conceptual maps and creating presentations from that, but then I found VUE which already fulfills my most import wishes.

Of course I have a long wishlist. My most important wish is more interactivity in presentations. I want to dive in and out into regions of my presentation whenevver there is need for it. Creating dynamic frames which allow me to zoom in an out of details are not interactively enough, since then I need to anticipate all questions which arise from my audience. But my audience will often ask questions which I did not anticipate, and then I would need to zoom into a detail of a picture where I did not place a dynamic frame.

My idea is to make more use of mouse input: while a presentation is running I want to use the scrollwheel to zoom in and out, from the whole map to any detail I want to see. When zooming in I want to have the current mouse position as zoom center, so that I can control to which detail I am zooming. Each right mouse button click should zoom out one step: from the detail to the slide, from the slide to the frame, from each frame to a bigger frame, until I see the whoile map. Short klick on left mouse button should move to the next slide, permanently pressing the left button should allow panning, and double-clicking the left mouse button should zoom in one step (frame hierarchy, dowsn to slide and then zooming into details).

And then I have the idea of using keyboard and mouse combinations. When a slide is displayed now I can toggle on and off a navigation tool using the "m"-button. Since I only need this navigation map very shortly, i.e. just to be able to jump to another slide, I would prefer when it is displayed only as long as I permanently press a key (why not CTRL). When I release the key the navtool would disappear.

And yet another wish: I feel when using "dynamic zoom" in presentations the transition between the views is quite abrupt. It would be great when it would take a second or only half of it for dynamic zoom where the audience could see the zooming act from the whole map or a larger region to a slide, a frame, a node or any detail.

You can learn quite a lot about intuitive interactive presentations from Prezi (http://prezi.com/) and even from pptPlex for MS Power Point (http://www.officelabs.com/projects/pptPlex/Pages/default.aspx).

Thank you
Tom

Thanks for the suggestions Tom. VUE is open-source and the source is all up on sourceforge so if you were considering starting your own project, it may be some of these features are things you may be interested in contributing. Regardless, thanks again for the thoughtful feedback on the presentations tools, you make some good suggestions.

Hello Mike, and thank you for your answer. Unfortunately I have never programmed Java, but of course I already downloaded the VUE sources and installed Eclipse. But I couldn't run the sources or build VUE from it yet, I guess that I need to exclude some of the sources (I read about that in the developer's corner in this forum). I'll continue my experiments when I have some free time over the summer.

I know that for many VUE users making presentations is probably not the most important task, but for me it is. Linear presentations like that from Power Point definitely are not only boring, they are indeed a source of risc and failure in science, engineering and economy. And they are definitely not the right tool for teachers. For me the most important feature of a presentation tool should be to give the audience a visual impression of how knowledge and ideas are connected. Knowledge doesn't grow linear, it grows by weaving a net.

This is the reason why I think that a really dynamic zoom (where the audience can see the process of zooming in, and experience that as a process of diving into a sea of ideas, lead by a presenter who acts as the dive master, knowing the really good spots ...) is so important. It's not just a nice gimmick, it is indeed an essential tool which enables the audience to visually recognize a mental path. "Dynamic zoom" as VUE does it right now (AFAIK) doesn't allow the audience to walk a mental path. It jumps from one view to another, and misses to give the audience the visual impression of walking a path between connected ideas.

I have also seen forum posts asking for 3D maps. I would support this and ask at least for some kind of 2.5D, where a presentation could "fly" over a map of nodes, slides and data, and discover the whole network from high above, diving into the details whenever necessary. But I also have a vague idea of a "full 3D" concept map, where areas with densely connected information are forming hills and mountains, while isolated and rather unconnected ideas form flat desert areas :-)
