Here's a PPT slide from the Pentagon military...
There are many books and articles about Power Point and personal presentations.
The only valuable thing I read on this topic was Godin’s short text on this link (English).
Quote about personal communication:
Communication is the transfer of emotions. Communication is about getting others to accept your point of view, helping them understand why you are excited (or sad, optimistic, etc.). And if all you want to do is create a bunch of facts and graphs, then cancel the meeting and just send them a written report.
I subscribe 100%. This is why I don't like conferences. Millions of slides and zero emotions. Although it should be the other way around
