A presentation program is a computer program that supports the preparation and presentation of a lecture or lecture .

Every single presentation slide or slide that is to be shown in the lecture is processed and saved with the presentation program. The slides combine text, images, graphic clips, diagrams, tables, film sequences and music files. They can be created on a uniform background ( layout ). The slides belonging to a lecture can be saved together in one file.

The slides can be shown with an overhead projector and printed out on a printer. In the university sector, they used to be transferred to slides and presented with a slide projector. This is why presentation programs used to be called Slideshows , in German Diashows, named after the English name Slide for the German word Diapositiv . Today you can program the sequence directly on the computer, bring it to the screen via a video projector and control it with a special remote control ( presenter ) by the presenter. Background music and sound is also possible.

Zooming Presentation

As an alternative to presentation techniques based on slides, there is a technique based on scalable user interfaces , in which the areas to be presented can be enlarged as required. The user prepares the content and creates a sequence path and the appropriate magnification level for what is to be shown at the moment. This path is followed during the presentation and only part of the entire content is shown at each stop. After the user has selected the next step, a flowing animation leads to the next breakpoint and zoom level. An example of this is Prezi .

3D based presentations

In another alternative called “Showroom”, the presentation is based on a 3D graphics engine (Falo3D) so that the user can experience the presentation content interactively in three dimensions. The tool can e.g. B. can be used for product presentations and interactive infographics. Individual camera positions can be set for interesting details, between which automatic camera movements can be defined. Alternatively, the user can move freely in the room and use the presentation interactively. Configurable body animations and other multimedia functions can e.g. B. can be used for product simulations.

Multimedia shows

Here, still images or movies to be projected with video projectors and voice or background music with simple speakers or surround systems to impressive multimedia - audiovisual combined presentations.

The shows are usually fully automated, with or without a presenter. Various cross-fading techniques and zooms make it possible to combine pre-programmed (possibly image-optimized) raw data. For example, it is possible to adapt the image resolution to the pixel resolution of the beamer even when zooming into the image in real time , which makes it easier to port a lecture to modified presentation hardware. Sometimes special effects (for example, projection onto a wall of water, 360 ° projections, 3D images or films , 4D, 5D and XD films , moving seats or smell cinema ) are used and controlled.
