A presentation conveys information from a speaker to an audience. Presentations are typically demonstrations, introduction, lecture, or speech meant to inform, persuade, inspire, motivate, build goodwill, or present a new idea/product. Presentations usually require preparation, organization, event planning, writing, use of visual aids, dealing with stress, and answering questions. “The key elements of a presentation consists of presenter, audience, message, reaction and method to deliver speech for organizational success in an effective manner.” Presentations are widely used in tertiary work settings such as accountants giving a detailed report of a company’s financials or an entrepreneur pitching their venture idea to investors. The term can also be used for a formal or ritualized introduction or offering, as with the presentation of a debutante. Presentations in certain formats are also known as key note address. Interactive presentations, in which the audience is involved, are also represented more and more frequently. Instead of a monologue, this creates a dialogue between the speaker and the audience. The advantages of an interactive presentation is for example, that it attracts more attention from the audience and that the interaction creates a sense of community.
A presentation program is commonly used to generate the presentation content, some of which also allow presentations to be developed collaboratively, e.g. using the Internet by geographically disparate collaborators. Presentation viewers can be used to combine content from different sources into one presentation. Some of the popular presentation products used across the globe are offered by Apple, Google and Microsoft.
Microsoft PowerPoint and Google Slides are effective tools to develop slides, though Google Slides allows groups to work together using Google Drive to update each account as it is edited. Content such as text, images, links, and effects are added into each of the presentation programs to deliver useful, consolidated information to a group. Visual elements add to the effectiveness of a presentation and help emphasize the key points being made through the use of type, color, images/videos, graphs, layout, and transitions.
One common means to help one convey information and the audience stay on track is through the incorporation of text in a legible font size and type. According to the article “Prepare and Deliver an Effective Presentation”, effective presentations typically use serif fonts (e.g. Times New Roman, Garamond, Baskerville, etc.) for the smaller text and sans serif fonts (e.g. Helve tica, Futura, Arial, etc.) for headings and larger text. The typefaces are used along with type size to improve readability for the audience. A combination of these typefaces can also be used to create emphasis. The majority of the fonts within a presentation are kept simple to aid in readability. Font styles, like bold, italic, and underline, are used to highlight important points.
It is possible to emphasize text and still maintain its readability by using contrasting colors. For example, black words on a white background emphasize the text being displayed but still helps maintain its readability. Text that contrasts with the background of a slide also enhances visibility. Readability and visibility enhance a presentation experience, which contributes to the effectiveness of it. Certain colors are also associated with specific emotions and the proper application of these colors adds to the effectiveness of a presentation through the creation of an immersive experience for an audience.
Large images relevant to the presentation attract an audience’s attention which in turn can clarify the topics within the presentation. Using pictures sparingly helps support other presentation elements (e.g. text). Short videos are used to help the presenter reinforce their message to the audience. With the additional reinforcement that images and videos offer, the effectiveness of a presentation is further maximized.
There lacks a comprehensive list of criteria common among research studies or educational institutions in a typical presentation rubric used to assess presentations. Nevertheless, De Grez et al., in consultation with experienced higher education teachers, developed a rubric composed of nine evaluative criteria, of which five dealt with one’s manner of delivery (interaction with audience, enthusiasm, eye contact, vocal delivery, and body language), three were content related (structure, quality of introduction, and conclusion), and one evaluated general professionalism.
In computing, a presentation program (also called presentation software) is a software package used to display information in the form of a slide show. It has three major functions:
- an editor that allows text to be inserted and formatted
- a method for inserting and manipulating graphic images and media clips
- a slide-show system to display the content
Presentation software can be viewed as enabling a functionally-specific category of electronic media, with its own distinct culture and practices as compared to traditional presentation media (such as blackboards, whiteboards and flip charts).
Presentations in this mode of delivery have become pervasive in many aspects of business communication, especially in business planning, as well as in academic-conference and professional conference settings, and in the knowledge economy generally, where ideas are a primary work output. Presentations may also feature prominently in political settings, especially in workplace politics, where persuasion is a central determinant of group outcomes.
Most modern meeting-rooms and conference halls are configured to include presentation electronics, such as overhead projectors suitable for displaying presentation slides, often driven by the presenter’s own laptop, under direct control of the presentation program used to develop the presentation. Often a presenter will present a lecture using the slides as a visual aid both for the presenter (to track the lecture’s coverage) and for the audience (especially when an audience member mishears or misunderstands the verbal component).
Generally in presentations, the visual material is considered supplemental to a strong aural presentation that accompanies the slide show, but in many cases, such as statistical graphics, it can be difficult to convey essential information other than by visual means; additionally, a well-designed info graphic can be extremely effective in a way that words are not. Endemic over-reliance on slides with low information density and with a poor accompanying lecture has given presentation software a negative reputation as sometimes functioning as a crutch for the poorly informed or the poorly prepared.
Autographix, and Dicomed. It became quite easy to make last-minute changes compared to traditional typesetting and pasteup. It was also a lot easier to produce a large number of slides in a small amount of time. However, these workstations also required skilled operators, and a single workstation represented an investment of $50,000 to $200,000 (in 1979 dollars).
In the mid-1980s developments in the world of computers changed the way presentations were created. Inexpensive, specialized applications now made it possible for anyone with a PC to create professional-looking presentation graphics.
Originally these programs were used to generate 35 mm slides, to be presented using a slide projector. As these programs became more common in the late 1980s several companies set up services that would accept the shows on diskette and create slides using a film recorder or print transparencies. In the 1990s dedicated LCD-based screens that could be placed on the projectors started to replace the transparencies, and by the early 2000s they had almost all been replaced by video projectors.
The first commercial computer software specifically intended for creating WYSIWYG presentations was developed at Hewlett Packard in 1979 and called BRUNO and later HP-Draw. The first microcomputer-based presentation software was Cromemco’s Slidemaster, developed by John F. Dunn and released by Cromemco in 1981. The first software displaying a presentation on a personal computer screen was VCN ExecuVision, developed in 1982. This program allowed users to choose from a library of images to accompany the text of their presentation. Harvard Graphics was introduced for MS-DOS and Lotus Freelance Graphics was introduced for DOS and OS/2 in 1986. PowerPoint was introduced for the Macintosh computer in 1987.
