I love the description of big academic conferences as "Woodstock for Geeks." This is a brilliantly made cartoon by Mike Morrison, not only explaining the problem with poster sessions at conferences but putting forward a simple template for designing research posters as a practical help to overcoming the problem.
One part of the design idea is to include a QR code providing access to further information, papers and so on. My friends from Kubify have gone one step further producing mini posters linking to 'stacks' of interactive and multimedia material.
Kubify’s Learning Toolbox, they say, "is an award-winning ePoster platform and is a versatile tool that can also be used to support other event and education activities.
Learning Toolbox allows people to quickly and easily build their own stacks of interactive and multimedia material and share them with others. These dynamic stacks can be used as ePosters, research calling cards or learning resources."
Rich ePoster content
"A Learning Toolbox ePoster can contain many different rich resources such as videos, images, audio, apps, presentations, twitter and links to interactive online resources."
