VISUAL PRESENTATIONS

A picture is worth a thousand words

MEANING & DEFINITION

“By a 'visual representation' I mean roughly an item that is both visible itself, and which purports to represent some actual subject, in such a way that the representing item is in some way similar to, or recognizable as, the purported actual subject; and which item has a representational content or subject matter that may or may not accurately characterize any actual subject. Pictorial representation is one species of visual representation.”– John Dilworth (varieties of visual presentation)

METHODS OF VISUAL PRESENTATIONS

Tabulated data

Line Graphs

Bar Graphs

Gantt Charts

Pie Charts

Pictograms

Maps

Cartograms

Flow charts

Visual Planning

Boards

Computer Graphics

TABULATED DATA

Use of tabulated data:Tabulated data is used when a heavy amount data needs to be accessed and analyzed at a glance.

EXAMPLE OF TABULATED DATA

company’s location. Maps have obvious advantage over

the written word.

EXAMPLE OF A MAP

FLOW CHARTS

A flow chart is a graphical or symbolic representation of a process .

The flow chart symbols are linked together with arrows showing the process flow direction.

Use of Flow Charts:

To study a process for improvement.

When better communication is needed

between people involved with the same

process.

EXAMPLE OF A FLOWCHART

PIE CHARTS

Use of Pie charts:Pie charts are good at showing the

comparative sizes of multiple objects.

EXAMPLE OF A PIE CHARTS

CARTOGRAMSA cartogram is a map in which some thematic

mapping variable – such as travel time or Gross National Product – is substituted for land area or distance.

Geometry or space of the map is distorted in order to convey the information of this alternate variable

Main types of cartograms: area and distance cartograms

A distance cartogram is used to show relative travel times and directions from vertices in a network.

COMPUTER GRAPHICS

Mostly people find it difficult to read and remember information

They prefer to information in the form of graphics which is visually attractive and easily interpreted

Data can be quickly and easily interpreted through the medium of graphics

Most simplest form of graphic presentation are the graphs and pie charts

MNCs have started using Graphical software for better understanding and efficient working

EXAMPLE OF COMPUTER GRAPHICS

Murphy’s Laws for Visual Presentations

Whatever you forgot is what you will most need.The most critical point of any presentation will be mizpeled at least

once.

Presenters and rehearsals are similar to children and homework: They say that

they do it, but it's rarely done.There is never time or budget to do it right.There is always time and budget to do it over.YOU will be the expert on everything.Credit is to be given, blame is to be gracefully taken.All microphones are broken.All screens are too small.All projectors are too faint.

All presentation rooms are too small, too bright, too large, too dark, too

hot, too cold or all of these depending upon whom you ask..

DEADLY SINSOF

VISUAL PRESENTATIONS

RANSOM NOTE DESIGN

Just because you have access to 350 fonts does not mean that you are

required to use them. A single font throughout an entire presentation is

usually quite sufficient. Use bold, italic, underline, quotations and/or colour

changes to emphasize or subdue key points or words.

THE ILLEGIBLE IMAGE

Images not clearly seen by the entire audience add confusion and distraction. If you have to say "I know you can't read this but.....," why include the visual at all?

One popular rule of thumb is the "8H" rule of legibility. In a nutshell, if you can read an image from eight times its height, odds are your audience will be able to read it when projected

THE USELESS IMAGE

Images should be designed to please the mind as well as the eye of the viewer. If an image

has no specific place or purpose in a presentation other than "it is

pretty", it should probably be removed.

And again A picture is worth a thousand words.
