Prezi

Prezi is a platform independent cloud- dependent presentation program. The software can be created based on the Flash technology a presentation on a virtual, infinitely large sheet of paper, you move on through mouse control, as well as zoom in and zoom out can.

Creating a Presentation

Prezi is a web application with Adobe Flash and as a stand-alone application Prezi Desktop with Adobe AIR for Windows and Mac. In Prezi you are working on a presentation surface, the interactive whiteboard on which you can insert as text boxes, pictures or movies. The objects can then be enlarged, reduced, rotated and moved. Single objects can be connected with paths. The software has a multi-user mode, which is limited to ten people. The handling is described as intuitive.

A presentation can be used in a stand-alone Portable Prezi be exported and can be played on both Mac and Windows offline. Linux is possible to emulate this with a minimum of web servers, or exported for Windows Version by Wine run. In addition, there is a playback software for Apple iPad available. Various formats such as videos or images in a Prezi presentation are no longer individually exportable. This makes it difficult as well as the acquisition of parts of presentations, a machine searchability is not given.

Animation Timeline

If an object with another connected by a path, it looks in the presentation similar to an approach in Google Earth, only a zoom out, then the surface rotates so that the new object is aligned properly and finally to the optimal size zoomed. Critics go on this one animation effect that is both pleasant - as judged by others as unpleasant. The Learning Technology Support Service at University College London suggests that Prezi easily invites you to overdo.

Business Model

Prezi is based on a freemium business model. It is freely available on the Internet, anyone can create customized presentations and receive 100 MB of data storage. However, these are publicly available and marked with a Prezi logo. Prezi sells two versions: the cheaper allows the creation of non-public presentations, removes the Prezi logo and expanded the available space. The more expensive permits downloading of the editor and creating presentations offline. As a student and member of a faculty of his university there is also the possibility to use the "Enjoy" version of Prezi for free as part of a teaching career. This only requires that faculty identifier is required to be registered with respect to the e- mail address.

Alternatives

An alternative that is based on a similar principle, but is provided with a free license exists with social, an Inkscape extension that animates a SVG file with Java Script. Some projects also try to imitate the Prezi concept using free Web standards like CSS3 transformations, which so far the work is carried out directly in the source code. In order to achieve the comfort of Prezi, there are also attempts to create GUI editors in HTML5.

History

Prezi was developed by the Hungarian artist Adam Somlai -Fischer and the computer scientist Peter Halacsy 2007. They started Prezi as a presentation program for architectural firms. In 2008, they hired as CEO of the Swedish- Hungarian young entrepreneur Peter Arvai and in March 2009 they presented the program to the public. The headquarters of the company is located in San Francisco, another larger office is located in Budapest, where the software was also originally developed.

The investors heard since 2009 TED, as well as the venture capital firm Sunstone Capital. The consultants include, inter alia Twitter co-founder Jack Dorsey. The software is now also used regularly at TED conferences, as for keynotes at LeWeb or the Europeana Conference 2010. In a Lifehacker survey from September 2010 Prezi came under the five most widely used presentation programs, was defeated in the final result but clearly both PowerPoint and Apple's Keynote presentation software.
