Thinking on those researchers directly related with the Conference topics but unable to attend it personally (usually due to insufficient funding to cost all the conference expenses: travel, accommodation, registration, etc.), a Virtual Participation modality has been established, with the same validity than "physical" one (certificates, publications, etc.).

For this kind of participation, registered researchers will be requested to send "Virtual Posters" in "Power Point " format which will be exhibited at the virtual participation online platform. All virtual presentations will be shown in different formats: "Power Point", "HTML", and "Flash". Besides, the abstract of the corresponding work (previously submitted) will be included in "PDF" format.

The deadline for "Virtual Posters" submission will be 12 November 2007.

Each presentation will have an own forum where all interested researchers will be able to exchange information or opinions about it. Moreover, each registered author will have a personal account in the PMS (Private Message System) for a more direct and private communication with the researchers especially interested in his/her work.

In order to prepare your virtual presentation, here there are some advices that could be taken into consideration:

• If it is possible, please use Microsoft PowerPoint to prepare your presentation. And please try not to prepare presentations of more than 25 slides.

• Try to keep the appearance of your slides simple and as consistent as possible, e.g. by use of a recurring ‘style theme’.

• Consideration should be given to colour blindness when choosing colours for your presentation e.g. avoid use of red and green together on graphs.

• The colours and background of the slides have a large impact. White letters reversed out of a black background are far more effective than black letters on a white background. Likewise, the choice of colours should be considered e.g. yellow lettering on a blue background provides a good visual effect.

• Simple and effective graphics will enhance the presentation. Information presented in the form of ‘pie charts’, bar charts or graphs is easier to relate to and to understand than lists of information.

• Excessive use of animations (e.g. titles flying in from right & left) is not advised as these will probably distract the viewer and may detract from the content of the slide. If you wish to use these, please keep them as simple as possible.
