"Preparing Effective Posters
A poster should be self-contained and self-explanatory, allowing different viewers to proceed on their own while leaving the author free to discuss points raised in inquiry. The poster session offers a more intimate forum for discussion than the slide presentation, but discussion becomes difficult if the author is obliged to devote most of the time explaining the poster to a succession of viewers. Remember that the time spent at each poster figure is determined by the viewer, not the author, as in the case of slide presentations."
