Stay for the entire session, for the courtesy and benefit of your audience and your co-speakers. Complaints about poor presentations have been received for decades and continue to be received. The tips and suggestions are here to help you. Please put them to good use. An ad hoc committee was formed at the April 1999 ENAR business meeting, to address this persistent and pervasive problem.
Effective presentations make learning and technical advances more likely.
They also enhance the perception of the presenter in the eyes of the professional community. Boring, ineffective presentations are not paid much attention and often are quickly forgotten, especially by planners of future invited sessions. Allow time to describe the problem clearly enough for the audience to appreciate the value of your contribution. This usually will take more than 30 seconds. Leave enough time to present your own contribution clearly.
