Put your cue cards on index cards, one sentence per card, then you can't possibly read from no matter how much you want to, they have to be cues.
LISTEN to your audience- it's easy to panic and not answer questions properly. Set a time at the beginning for this- either say you're happy to be interrupted, or would prefer questions at the end.
Ditto the handouts- if you want a 'break' give them early, but if you're being judged hand them out last, as people know the trick too well! You'll get most respect for leaving them to the end. I usually present, hand outs, few minutes to skim (coffee?), then when they have had a chance to think of any questions, answer.
OHP's are good. The last presentation I did I simply put relevant quotes on them, as they came in and used this to 'set the scene'. In my days as a fundraiser, I used to put up photos, either of people in events, patients or facilities we had funded. Corporate logo on all.
Make eye contact, smile a lot and use mild humour if appropriate. Best presentation I ever gave was at a job interview, I downloaded half theoir website to make handouts (it looked wellr esearched and they pee'd themselves laughing) and added in loads of pics, making sure I covered all aspects of ethnicity / disability /etc, so hammering home the message I'm an equal ops kinda person.
Worst one I ever gave was last yar on a college course, about omething I didn't really understand however much I had researched. Made slightly better by my mate after who had chosen to do corporal punishment and started with photos of slippers / whips / belt. At least I didnt look like a perv!!!!
