For presenters with a written presentation, either as transparencies or electronic, be aware that slides transmitted over video conferencing lines lose a lot of resolution, and must be viewed by people who may be at some distance from the local TV screen. Use a point size of 36 for your text to ensure readability, and a white background with black text is also advised. Also avoid use of small graphics and most kinds of web pages, which often have fine details and small text that are impossible to see after transmission across video conferencing lines.
If possible, provide your audience, both local and remote, handouts for your presentation. This should be done ahead of time so that a person at the remote site can have time to make copies to hand out to participants. This will make it much easier for the audience to follow, and is particularly important if your presentation cannot for one reason or another meet the size recommendation above.
Increase the overall effectiveness of the presentation by:
· Wearing solid colors (blues and khakis work well--avoid red, white, black, stripes, loud prints,or plaids).
· Avoiding audio feedback problems by asking the site(s):
(i) to mute their microphones when no one from that site is speaking' or
(ii) to place the microphones well away from the main monitor's speaker system.
· Maintaining appropriate on-camera positioning.
· Moving slowly but naturally.· Speaking slowly, distinctly.
