A computer presentation is ... Definition, stages of creation, history and types

Computer presentation is a special document with multimedia content, the demonstration of which is controlled by the user. At the moment it is one of the most popular ways of presenting information, which is used in many spheres of life.

What is a computer presentation

Quite often an oral presentation or a written report requires visual accompaniment and visual presentation of information. In this case, a computer presentation can be used. This is a certain sequence of slides or a video sequence. This is a file that contains all the necessary information for the performance of the performance.

Basic terminology

Concerning computer presentations, the following terminology is often used:

• Interactivity - the property of presentation, which means the possibility of adjusting it with the direct participation of the speaker;
• A hyperlink is a slide object that, when pressed, allows you to go to an external source;
• Animation - dynamic effect, which provides movement of the object on the slide area;
• The project is a schematic description of the future computer presentation;
• Multimedia - the use of files and effects of a different kind within a single slide.

Types of computer presentations

Despite the fact that this is a fairly common phenomenon, not all definitely know what kind of computer presentations are. So, for now, the following main types are distinguished:

• Slide presentations are classified as static, because they demonstrate a still image, which can only be changed through specific user actions;
• Streaming (dynamic) presentations are sets of frames that are themselves replaced after a period of time that lasts less than one second.

Concepts such as interactive presentation and script can also be highlighted. In the first case, the speaker actively interacts with the computer device in order to find the right information. If we talk about the scenario, then we are talking about a clear sequence of slides, which are replaced after a certain period of time.

What is a slide?

Slides are frames that contain the information necessary for the presentation. It is worth noting that they are not recommended to be overloaded with an abundance of information. The viewer should spend a minimum of time identifying and analyzing the data shown on the slide. That's why only the main excerpts and the necessary demonstration material are included .

Slides can contain the following information:

• Headers and sub-headings that have data about the contents of the file;
• Graphic images (pictures, photos, graphics, diagrams, etc.);
• Tables with digital or text data;
• sound accompaniment;
• Text file;
• Labeled or numbered lists listing data;
• Background image that facilitates the perception of information or carries an aesthetic function;
• Headers and footers (contain numbering, footnotes or other additional data);
• Hyperlinks to external objects.

Recommendations for the development of

A computer presentation is a visual presentation of a textual report that contains visual information. That it was perceived better, it is necessary to be guided by the following recommendations:

• Use of short sentences and words that are available for understanding;
• There should be as few prepositions and introductory words as possible;
• Use bright headlines that attract attention and reflect the essence of the content;
• It is recommended to place within a single slide no more than three information objects ;
• For the key points of the report, select individual slides, and do not try to fit all the information into one;
• Slides with horizontal orientation are best perceived;
• Key information should be located in the center of the screen;
• Signatures to pictures should be under, not over them;
• Try to have on the slide no more than 8 lines, each of which contains about 30 characters;
• For good readability of text use large-sized fonts without sans serifs;
• All slides must be consistent in a single style;
• For color design it is better to choose cool tones;
• Do not overuse the animation effects, so they do not distract attention from the basic information.

Stages of creation

In order to create high-quality material, go through the following stages of creating a computer presentation:

• The development of the structure of the future information file, as well as the general concept;
• Next, a post-script scenario should be outlined (it will not be final, may be subject to adjustment);
• Adding all necessary objects (text fragments, drawings, etc.);
• Setting animation effects, which will be accompanied by a slide change;
• Subsequent editing, as well as sorting the slides in order to establish their correct sequence;
• Start and preview.

History of computer presentations

The history of the development of computer presentations can be considered by the example of a software product such as Microsoft Power Point, which is most often used for these purposes. Initially, it was named Presenter. The program was created by two students who felt that it was time to look for new ways of submitting information.

Initially, the program worked only in black and white mode, after which its color version was developed. At the same time, a rather weighty volume was published, which contained a detailed guide to the use of the program. But since this idea proved to be quite costly, it was soon discarded.

Over time, the program has adapted to different operating systems and has been gaining new opportunities. There were functions of animation, binding hyperlinks and much more. Following the concept of this product, a computer presentation is a document that is perceived as a single set of slides, rather than a collection of individual files.

Areas of application of computer presentations

Having dealt with what a computer presentation is, it is necessary to determine the scope of its use. So, it finds application in the following areas:

• Submission of material in the educational process;
• Placement of control tasks for schoolchildren and students;
• Advertising activities related to goods and services;
• Creation of albums with photos or other images;
• Visual support of reports;
• Other.

The procedure for creating a presentation

Computer presentation on computer science is created as follows:

• Launch of Microsoft Power Point;
• In the window that opens, you enter a title and, if necessary, a subtitle of the slide;
• Add the desired number of slides by running the "Insert - Create Slide" command;
• Start the presentation using a special command or F5 key, review it and, if necessary, make corrections.

Key issues in developing

In order for the presentation to have the right effect, the right tasks must be set before it. For this, clear answers are given to the following questions:

• Target audience, which is planned to impress (this depends not only on the form of submission of information, but also on the design of the slides);
• Effect, which is planned to be achieved after the performance (to sell the product, get a loan, demonstrate the invention, etc.);
• Correctly define the presentation object in order to concentrate on it, without being distracted by minor moments;
• Identifying key features or factors that the audience should pay attention to;
• The most successful way to demonstrate a presentation (on a shared screen or on individual computer devices).

conclusions

A computer presentation is a set of slides through which visual support is provided for an oral or written report. This allows you to improve the perception of information by presenting key points. Demonstration of the presentation can be carried out on the general screen, projector assistance or on individual computer devices.

Presentations can be slides or streams. The second is a continuous video, which is broadcast during the course of the report. As for slide presentations, they can have a clear script with automatic change, and can be interactive. This means that the speaker himself is looking for information and regulates the change of personnel on the screen.

Slide is the main element of the presentation. It contains information such as headers, footers, text fragments, pictures, tables and other information. In order for the information to be perceived in the best way, a number of requirements are put forward to the slides. So, it is not recommended to place more than three objects, and lines of text should be a maximum of 8. It is better to use cold background colors, since they do not act so irritatingly on the eyes.

Before you start creating a presentation, you need to first outline the structure of the slides, as well as the concept that will unite them. It is also worthwhile to draw up a preliminary scenario, according to which the personnel will replace each other. Now you need to add all the necessary elements to the presentation file, and then make the appropriate adjustments. Start the slideshow to ensure that they are in the correct sequence.

When developing a presentation, it is important to answer a number of questions. The design will largely depend not only on the purpose and theme of the presentation, but also on the audience to whom the report is read. Try to highlight the key factors and the essence of the idea, without overloading the slides with superfluous and secondary information.
