1. Computer based Presentation

The availability of affordable software and new technology has made computer based presentations the visual aid of choice in most business situations. What used to take weeks of preparation and an outside production house can now be created by you at your desktop. Computer-based presentations can be real-time or prepared in advance. Real-time presenting is useful when the audience needs to see immediate results or the software in action–like financial brainstorming sessions or software training.

3. 35mm Slides

The content of 35mm slides provides a crisp, colorful, easy to read format for presenting information. 35mm slides are the most universally accepted way to show full-color, three-dimensional still pictures. They are also used extensively to show graphics or pictures. Slides can be used with large or small audiences and, because the projectors are small and portable, they can be taken almost anywhere. Remote operation allows you to move around the room and still control the duration and sequence of each slide in Development Support Communication.

One should not assume that investing a lot of money in high tech visual aids & equipment will “make” our presentation. The best visuals have been and still are the simplest.Whether hand-written or professionally imaged, the flip chart remains one of the most popular means of presenting meeting room information.

6. Whiteboard

The chalkboard is probably the oldest in Development Support Communication, most familiar visual aid. It has evolved over the years from the standard black or green hard chalk variety to whiteboard that requires the use of liquid markers. Information can now be written quietly, in brighter colors, and erased completely with considerably less effort. Whiteboards are inexpensive, easy to use, and best suited for small groups where brainstorming sessions or spontaneous illustrations are necessary.

In the early 19th century scientists took note of a visual phenomenon: A sequence of individual still pictures, when set in motion, can give the illusion of movement. These scientists attributed this experience to what they called persistence of vision, whereby the eye retains a visual image for a fraction of a second after the source has been removed. The eye’s retention of a visual image, now known as positive afterimage, has long been considered a founding principle of motion pictures, even though its relationship to the perception of motion is still not well understood.

Video cassettes and recorders i.e. VCRs are another form of this recording system. But to use them TV is a mandatory thing as it has to record visuals with the audio. Invention of VCR added a lot to the usefulness of recording system and of course communication. For development purposes, promoting education and running awareness campaigns VCRs are equally used with cassette player or tape recorders/ players. Cassette players in the form of Walkman’s are also used on a large scale especially by youngsters/ teenagers for entertainment and fun
