Electronic presentations: what they are for, characteristics, elements

The electronic submissions They are a didactic resource where audiovisual elements are used to create digital slides. These slides are supported by multimedia resources such as videos, animations, audio or graphics.

The electronic presentations constitute a visual support when the speaker is transmitting information on a subject, and they are projected through a computer. In these slides you can create texts, diagrams and the important points of the conference, class or exhibition that is being done.

They are made on a computer, and are an attractive way to capture the attention of the public. Power Point is one of the tools that is usually used to create these computer products in the form of sheets or slides. Pages like Slideshare use them as part of their information strategy to present the concepts they offer.

To play the electronic presentations you will need a computer and a video projector. Before, projectors were used, which had a slot to insert the slides.


What are electronic submissions used for?

To make oral presentations

The electronic presentations serve to illustrate and support any exhibition, keep the audience’s attention through the images and highlight relevant information, as well as organize it.

They are a way to energize oral presentations, such as speeches, conferences, workshops or classes, and a very effective resource for transmitting information to a large audience and keeping them interested.

to persuade

Likewise, they help to convince the audience, especially when it comes to advertising presentations before potential clients. In this sense, they serve to motivate and sell, and can be a deterrent.

Dynamize learning

In the educational field they are usually an element of great impact, since they reinforce learning through images, specific texts, videos and animations, and multiply their power of communication.

As a didactic resource, they allow the audience to more easily grasp the content of the talk. It is said that a speaker can express up to 130 words per minute, but the receiver can only take notes at 40 words per minute; the presentations give time to better understand the concepts and ensure a higher percentage of transmission and effectiveness of the message.

In summary, they fulfill different and defined objectives, depending on the nature of the exhibition, and function as a kind of script for the speaker, who will be able to paraphrase what is written in full view of all.

Characteristics of electronic presentations


The content on each slide or sheet must be direct, precise and concise. It is not recommended to fill it with text or objects (such as tables, graphs, etc.) as it will look very overloaded visually.

Rather, each slide should refer to a specific point of the conference, and serve as didactic support and reinforcement.


The size of the letter, the font used, the spacing, all these typographical elements, must be consistent. The size of the letters should be large enough so that reading them does not constitute an additional effort that interrupts the viewer’s attention.

The font cannot be a decorative element; word processing packages usually include a very large variety of fonts, and it is best to choose one that is easy to read, round and clear, avoiding those script or gothic types, which do not facilitate reading (the most recommended are Verdana, Times New Roman or Tahoma).

In any case, the font types used should be limited to three, since more than that tends to become visual noise.

The line spacing will have to be appropriate and comfortable to look at, with which the sheets do not look cluttered.


Although the images are independent, they must always allude to the ideas expressed in the class or conference, otherwise they become noise.

Images can be graphs, mind maps, drawings, photographs, or any type of illustration.


Electronic submissions must have the information outlined. Only then can you communicate effectively. In this sense, outlining the data is useful both for the presenter (who clarifies the concepts he is explaining to himself) and for the listeners, who will better retain what they are told.

Elements of electronic submissions

It could be said that the elements of an electronic presentation are basically two: the text and the image. We could add the format or design and the parts in which the presentation is divided.


As we mentioned before, the text should be clear and concise, each sheet containing a single concept. If possible, avoid filling the slide completely, it gives a confusing impression. A good slide will contain between 30 and 50 words.

The text will be aligned, and the alignment can be used to differentiate the slides. For example, use centered alignment for central concepts, right to indicate quotes or examples, and left for basic concepts. The alignment gives a sense of order.

Regarding the number of slides with text, it will logically depend on the length of the talk, but as a general rule, 15 will be enough.


On the other hand, the presentation works like the speaker’s notes: the notes are not extensive, they are only the main ideas on which the content of the talk will be developed. This is how the slides should also be presented, as notes.


Images are a resource to clarify concepts, to «see» graphically what has been explained in words. As an image, its function is mnemonic, that is, they help to remember.

In the case of graphics, you have to make them as attractive as possible, as they reinforce the cognitive function that allows the public to understand more complex data, such as figures.


The format includes all those visual resources that generate coherence and clarity in the slides. In this sense, all the sheets must present the same range of color and background.

An excessively colored slide makes reading difficult, distracting and does not fulfill its support function. It is better to opt for light colors for the background and a darker color for the typography. Very showy margins and frames must be avoided as far as possible: they are visual noise.

Experts recommend that you use up to three colors: a very light base color for the background, another for the body (usually black) and another for the titles, which you can combine with the other two and bring out the levels.

Electronic Filing Parts

The parts of an electronic presentation are the cover, the body and the references.

Front page

The title of the talk, the author and the topics that will be developed should be mentioned on the cover, presented very briefly.


It is the central and main part of electronic presentations. Here are all the slides from the talk, both the ones that contain text and images.


It is where all the sources consulted to prepare the presentation are cited. They are the final blades.

Examples of electronic submissions

The YouTube platform often uses electronic presentations to support its content, as well as SlideShare; the latter always presents the information in sheets.

The most used programs are Microsoft Power Point, OpenOffice and Prezi. The first two create slides (slides) in which text boxes, images –drawings, graphics– and videos are inserted.

Prezi is an online application based on a canvas, instead of separate slides. It is a kind of visual map that allows a non-linear structure, using zoom on each object. With its free version you can edit, teach and download the presentations.
