A computer presentation is a special document with multimedia content, the demonstration of which is controlled by the user. At the moment, this is one of the most popular ways of presenting information, which is used in many areas of life.
What is a computer presentation?
Quite often, an oral presentation or a written report requires visual accompaniment and the visual presentation of information. In this case, a computer presentation may 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.
Basic terminology
Regarding computer presentations, the following terminology is often used enough:
- interactivity - a property of the presentation, which means the possibility of adjusting it with the direct participation of the speaker;
- a hyperlink is a slide object that, when clicked, allows you to go to an external source;
- animation - a dynamic effect that ensures the movement of an object in the slide area;
- a project is a schematic description of a future computer presentation;
- multimedia - the use of files and effects of various kinds within a single slide.
Types of computer presentations
Despite the fact that this is a fairly common phenomenon, not everyone definitely knows what computer presentations are. So, at the moment, the following main types are distinguished:
- slide presentations belong to the category of static, because they show a still image, which can be replaced only through certain user actions;
- streaming (dynamic) presentations are sets of frames that are independently replaced after a period of time lasting less than one second.
Concepts such as interactive and scripted presentations can also be highlighted. In the first case, the speaker actively interacts with a computer device in order to find suitable information. If we talk about the scenario, then we are talking about a clear sequence of slides that are replaced after a certain period of time.
What is a slide?
Slides are frames that contain the information necessary for a 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 is why you should include only the main excerpts and the necessary demonstration material.
Slides may contain the following information:
- headers and subheadings that have data about the contents of the file;
- graphic images (pictures, photographs, graphs, charts, etc.);
- tables with digital or text data;
- sound accompaniment;
- text file
- bulleted or numbered lists listing the data;
- a background image that facilitates the perception of information or carry an aesthetic function;
- headers and footers (contain numbering, footnotes or other additional data);
- hyperlinks to external objects.
Development Recommendations
A computer presentation is a visual accompaniment to a text report containing visual information. To make it better perceived, you need to be guided by the following recommendations:
- use of short sentences and words that are understandable;
- as few prepositions and opening words as possible should be applied;
- Use vibrant headlines that capture attention and reflect the essence of the content.
- it is recommended to place no more than three information objects in one slide;
- highlight individual slides for key points of the report, and do not try to fit all the information into one;
- slides with a horizontal orientation are best perceived;
- key information should be located in the central part of the screen;
- image captions should be under, not above;
- try to place on the slide no more than 8 lines, each of which contains about 30 characters;
- For good readability, use large sans-serif fonts;
- all slides should be in the same style;
- for color design it is better to choose cold tones;
- Do not abuse animation effects so that they do not distract attention from the main information.
Stages of creation
In order to create high-quality material, they go through the following stages of creating a computer presentation:
- development of the structure of the future information file, as well as the general concept;
- then a slide scenario should be outlined (it will not be final, may be adjusted);
- adding all the necessary objects (text fragments, pictures, and so on);
- setting animation effects that will accompany the change of slides;
- subsequent editing, as well as sorting slides in order to establish their correct sequence;
- launch and preview.
History of computer presentations
The history of the development of computer presentations can be considered on the example of such a software product as Microsoft Power Point, which is most often used for these purposes. Initially, it was called Presenter. The program was created by two students who felt that it was time to look for new ways to present 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 folio was published, which contained a detailed guide to using the program. But since this idea was quite costly, it was soon discarded.
Over time, the program adapted to different operating systems and received all new features. There are animation functions, hyperlink bindings and much more. Following the concept of this product, a computer presentation is a document that is perceived as a single set of slides, and not a set of separate files.
Areas of application for computer presentations
Having understood what a computer presentation is, it is worth identifying the scope of its use. So, it finds application in the following areas:
- supply of material in the educational process;
- placement of control tasks for pupils and students;
- promotional activities regarding goods and services;
- creating albums with photos or other images;
- visual accompaniment of reports;
- other things.
Presentation order
A computer presentation on computer science is created as follows:
- launch of Microsoft Power Point ;
- in the window that opens, enter the title and, if necessary, the subtitle of the slide;
- add the required number of slides by executing the "insert - create slide" command;
- start the presentation using a special command or the F5 key, review it and, if necessary, make adjustments.
Key development issues
In order for the presentation to have the proper effect, the right tasks must be set for it. For this, clear answers are given to the following questions:
- target audience, which is planned to impress (not only the form of presentation of information depends on this, but also the design of the slides);
- the effect that is planned to be achieved as a result of the performance (to sell a product, get a loan, demonstrate an invention and so on)
- correctly determine the object of the presentation in order to concentrate on it, without being distracted by secondary issues;
- identification of key features or factors that are worth paying attention to the audience;
- the most successful way to demonstrate a presentation (on a common 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 a common screen, using the projector or on individual computer devices.
Presentations can be slide or streaming. The second is a continuous video sequence, which is broadcast during the report. As for slide presentations, they can have a clear script with automatic change, and can be interactive. This means that the speaker independently searches for information and regulates the change of frames on the screen.
A slide is the main element of a presentation. It contains information such as headers, footers, text snippets, figures, 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 there should be a maximum of 8 lines of text. It is better to use cold shades of the background, since they do not irritate the eyes so much.
Before you start creating a presentation, first you need to outline the structure of the slides, as well as a concept that will combine them. It is also worthwhile to draw up a preliminary scenario according to which frames 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 slide show to make sure 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 topic of the presentation, but also on the audience to whom the report is read. Try to highlight exactly the key factors and the essence of the idea, without overloading the slides with unnecessary and secondary information.
