Read from your slides so you don't forget your content.

Taking any/all of these steps will help to improve the delivery of your presentation:

==> Be familiar with the place the presentation will be given.

==> Practice your presentation.

==> Move away from your computer frequently while speaking, and return to it to advance slides.

==> Use your conversation words and voice.  Don't read it from a paper (unless you can write in conversational words and phrases, but this is really hard to do).

==> Look around the audience while you're talking.  Make eye-contact with people.

==> Let your hands move normally while you talk.  Smile.

-- Read from your slides so you don't forget your content.   ==> No. This is considered one of the signs of a poor presentation, and an inadequately prepared presenter.  

You're not there to read the slides to your audience.  They can read the slides just as well as you can.  You're there to explain, embellish, enhance, and enlarge the material on the slides.  If you don't have any more to tell them except what's on the slides, then you don't even need to drag yourself or the audience through the agony of the presentation. Just print the slides onto a handout, hand it out, dismiss the audience, and take the rest of the day off.  

Also, you're expected to know your subject well enough so that you don't need to read your slides to know what you're talking about, and to be well enough prepared to remember what comes next.
