In academia, it is common practice to make posters of your abstracts for national conferences. Once you are done presenting, what DO people do with the posters? I have several posters rolled up in my garage collected over the years.
If the answer is nothing, why can’t we find a more creative way to display static (or even video) content during abstract sessions? Perhaps use a large LCD screen instead of posters taped to a backboard?
Or a top-down video projection of your “poster” on a white canvas screen?
Clearly the technology exists, but costs are still prohibitive on a large-scale basis (i.e. convention hall with hundreds of abstracts). Just a question to make you go hmm.
