Tip: You and your visuals

Using visuals of any sort in a presentation has to be as unobtrusive as possible.
The first step here is being prepared.
If you can practice beforehand, do so.
Organise physical objects so that you can reach them when they are needed, without having to search, and without having to fumble. This may mean arranging them in the order in which they will be presented. It may mean practising the presentation so that you know automatically where to reach for something. This can apply to objects you want to display, the remote control for projecting equipment, the pens for flip charts or overhead projectors or a whiteboard, or to slides or overhead transparencies.
During these practice sessions, work out how you will move around the visual supports and equipment. Where will you place the objects you want to pick up – on a table, or another piece of furniture? Where will this, or the equipment, be so that you can move around it and communicate most easily with your audience – in front of you, beside or behind you? Always consider the least distracting way of accessing your material and the greatest ease of movement.
If you are using projection equipment, visualise its placement. Think about how you will work with the laptop or the overhead projector – standing beside, or behind? Do you want your silhouette projected on the screen as well as your visuals? Walking in front of the screen will also obscure them.
If you cannot organise the positioning of your equipment, then try to become familiar with it before the presentation and then visualise how you will use it best.
