Offline communication and presentation give a range of possibilities to deliver your ideas in the most efficient way. On the one hand you can’t rely on your personal intonation or appearance, but you can make visitors like your web-site, using some specific techniques.

By visual channels we don’t talk about means for delivering video or a sequence of frames, but the channel of perception. It is the way you get the information. There are 5 main channels that deliver you the data about the world around: visual, tactile, olfaction, audition and taste. There are only 2 of them that can be affected through the web.

The essential fact about the web is that the key role is played by the visual information. As we know, the information theory of visual communication encompasses the following aspects:

1. Image gathering – the capture of the radiance field.

2. Signal coding – encoding of the acquired signal for the further transmission and/or storage.

3. Image restoration – transforming digital representation of the scene into a continuous.

4. Human vision – image systems assessment (information rate that the eye of the observer conveys from the displayed image to the higher levels of the brain).

In the real world more than 75% of the information is received through the visual channel. You can also implement audio effects, nut there are plenty of shortcuts of using sounds online. Actually, it is not recommended.

For example, when making a presentation, we’d rather use slides and video, than just keynotes without any slides. A set of slides is an effective part of a talk, that represents a visual channel complementing the audio channel (spoken words).

Be sure, that visual elements you choose match your words. Visual channel needs to make the same point, but in a different way. The same thing is also relevant for photos – they should tenuously go with the talk. Images not only make your presentation more vivid, but also serve as a source of important information.

Use simple diagrams and info graphics that help to illustrate, and thus better explain, your word through their visual positioning.

As for motion, it’s not uncommon to use animations on slides, but do not overestimate the capabilities of the presentation software. You can practically always use fancy 3D cube rotation animation and flash animation for semantically rich visual channel.

So, use visual effects that are not only eye-candy, but also help communicate the point you are making. Use your voice as the main audio source when making a presentation, but avoid sound on your web-site.

Presentations are a part of everyday corporate life. Every company from automobile companies to newspapers, right down to the phone company and hardware manufacturers require presentations quite often to explain and/or illustrate how their business is running, showcase budgets and chalk out plans. An integral part of these presentations are charts. For effective data visualization which will convey and not confuse we need to use expressive charts that can present the given data in an aesthetic manner.

Recently, as I was making a series of slideshows for various presentations, I felt the need to make charts and realized that most of these looked very boring and difficult to comprehend. On investigation, I found a series of charting software that let one create visually arresting charts and tables based on an Adobe Flash Platform. These charting software are available at a price as well as free and are also very easy to use.

These presentation charts allow for greater variety and ensure that the attention of the audience is firmly on the information displayed at all times. The charts can also be made interactive by nature which makes it possible to insert drill-down options which could lead to another link or another function; one can include a mouse over option which will allow the viewer to access more details; one could also physically twirl the chart around to better illustrate the data showcased. The drag option lets the viewer play around with the icons further and also lets someone add secondary functions that can be accessed with the click of a mouse.

Flash charts effectively make your presentation look really good without compromising on data inclusion or comprehensibility. In fact, it makes it a lot easier for the viewers. Once the charts are better looking, the viewers want to pay attention. In addition to this we find that effective charting also allows to a greater amount of information to be included within a compact chart which means that we save both on space and complexity. The software required is freely available and are accompanied by efficient tutorials to explain their usage.
