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: [1]

Contents

Presentation software can be viewed[ by whom? ] 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.[ citation needed ]

Most modern meeting-rooms and conference halls are configured to include presentation electronics, such as 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[ by whom? ] 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 infographic 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.

Using Autographix and Dicomed, it became quite easy[ dubious ] 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.[ citation needed ]

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. [2] [3] [4] 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. [5]

Features

A presentation program is supposed to help both the speaker with an easier access to his ideas and the participants with visual information which complements the talk. There are many different types of presentations including professional (work-related), education, entertainment, and for general communication. Presentation programs can either supplement or replace the use of older visual-aid technology, such as pamphlets, handouts, chalkboards, flip charts, posters, slides and overhead transparencies. Text, graphics, movies, and other objects are positioned on individual pages or "slides" or "foils"[ citation needed ]. The "slide" analogy is a reference to the slide projector, a device that has become somewhat obsolete due to the use of presentation software. Slides can be printed, or (more usually) displayed on-screen and navigated through at the command of the presenter. An entire presentation can be saved in video format. [6] The slides can also be saved as images of any image file formats for any future reference. [7] Transitions between slides can be animated in a variety of ways, as can the emergence of elements on a slide itself. Typically a presentation has many constraints and the most important being the limited time to present consistent information.

Many presentation programs come with pre-designed images (clip art) and/or have the ability to import graphic images. Some tools also have the ability to search and import images from Flickr or Google directly from the tool. Custom graphics can also be created in other programs such as Adobe Photoshop or GIMP and then exported. The concept of clip art originated with the image library that came as a complement with VCN ExecuVision, beginning in 1983.

With the growth of digital photography and video, many programs that handle these types of media also include presentation functions for displaying them in a similar "slide show" format, for example iPhoto. These programs allow groups of digital photos to be displayed in a slide show with options such as selecting transitions, choosing whether or not the show stops at the end or continues to loop, and including music to accompany the photos.

Similar to programming extensions for an operating system or web browser, "add ons" or plugins for presentation programs can be used to enhance their capabilities.

Apps can enable a smartphone to be a remote control [8] for slideshow presentations, including slide previews, speaker notes, timer, stop watch, pointer, going directly to a given slide, blank screen and more. Presentation programs also offer an interactive integrated hardware element designed to engage an audience (e.g. audience response systems, second screen applications) or facilitate presentations across different geographical locations through the internet (e.g. web conferencing). [9] Hardware devices such as laser pointers and interactive whiteboards can ease the job of a live presenter .

Multimedia is a form of communication that uses a combination of different content forms, such as writing, audio, images, animations, or video, into a single interactive presentation, in contrast to traditional mass media, such as printed material or audio recordings, which feature little to no interaction between users. Popular examples of multimedia include video podcasts, audio slideshows, and animated videos. Multimedia also contains the principles and application of effective interactive communication, such as the building blocks of software, hardware, and other technologies. The five main building blocks of multimedia are text, image, audio, video, and animation.

In computing, an icon is a pictogram or ideogram displayed on a computer screen in order to help the user navigate a computer system. The icon itself is a quickly comprehensible symbol of a software tool, function, or a data file, accessible on the system and is more like a traffic sign than a detailed illustration of the actual entity it represents. It can serve as an electronic hyperlink or file shortcut to access the program or data. The user can activate an icon using a mouse, pointer, finger, or voice commands. Their placement on the screen, also in relation to other icons, may provide further information to the user about their usage. In activating an icon, the user can move directly into and out of the identified function without knowing anything further about the location or requirements of the file or code.

<span class="mw-page-title-main">Visual communication</span> Method of communication

Visual communication is the use of visual elements to convey ideas and information which include signs, typography, drawing, graphic design, illustration, industrial design, advertising, animation, and electronic resources. Visual communication has been proven to be unique when compared to other verbal or written languages because of its more abstract structure. It stands out for its uniqueness, as the interpretation of signs varies on the viewer's field of experience. The interpretation of imagery is often compared to the set alphabets and words used in oral or written languages. Another point of difference found by scholars is that, though written or verbal languages are taught, sight does not have to be learned and therefore people of sight may lack awareness of visual communication and its influence in their everyday life. Many of the visual elements listed above are forms of visual communication that humans have been using since prehistoric times. Within modern culture, there are several types of characteristics when it comes to visual elements, they consist of objects, models, graphs, diagrams, maps, and photographs. Outside the different types of characteristics and elements, there are seven components of visual communication: color, shape, tones, texture, figure-ground, balance, and hierarchy.

VCN ExecuVision, a combination graphics program and file manager, was the first presentation program for the personal computer, created by Visual Communications Network, Inc. and published by Prentice-Hall, Inc. for the IBM PC in 1984. The program's pre-loaded graphics library and its separate additions make the VCN ExecuVision the first professional digital clip art library. Featuring ten different typefaces, 64 color schemes, clip art, animation options, the ability to import images and the ability to draw freehand using a mouse, this program allowed users to manipulate graphics and text built with business data presentation in mind but could be used for all visual communication purposes. The program's capabilities were expanded with the release of six supplemental graphics libraries sold as individual floppy disks, which were to be joined by four more said to be in production but were ultimately never released. All of these functions required PC DOS 1.01, 128KB RAM, two disk drives, a color monitor and color graphics adapter to operate, as well as either an IBM dot-matrix or Hewlett-Packard printer to print visuals created within the program.

<span class="mw-page-title-main">Audiovisual</span> Electronic media with both a sound and a visual component

Audiovisual (AV) is electronic media possessing both a sound and a visual component, such as slide-tape presentations, films, television programs, corporate conferencing, church services, and live theater productions.

Document cameras, also known as visual presenters, visualizers, digital overheads, or docucams, are real-time image capture devices for displaying an object to a large audience. Like an opaque projector, a document camera is able to magnify and project the images of actual, three-dimensional objects, as well as transparencies. They are, in essence, high resolution web cams, mounted on arms so as to facilitate their placement over a page. This allows a teacher, lecturer or presenter to write on a sheet of paper or to display a two or three-dimensional object while the audience watches. Theoretically, all objects can be displayed by a document camera. Most objects are simply placed under the camera. The camera takes the picture which in turn produces a live picture using a projector or monitor. Different types of document camera/visualizer allow great flexibility in terms of placement of objects. Larger objects, for example, can simply be placed in front of the camera and the camera rotated as necessary, or a ceiling mounted document camera can also be used to allow a larger working area to be used.
