Nokia released a research prototype called Easy Meet today that looks like it might solve an issue that I noticed in my Philosophy 105 lectures this winter.
A weekly feature of the lectures was a PowerPoint projected on the big screen in the lecture theatre. Several times I found myself wanting to share things from the “audience” — web pages, images, PDF files — but there wasn’t an easy mechanism for doing this in real time.
While Easy Meet if obviously targeted at business meetings, there’s no reason why it couldn’t be used in an academic setting; in theory this would allow the sort of two way sharing that I was looking for: anyone with a laptop or mobile phone could share media with the class, and then others could annotate that media, and so on. It would be neat to try it out in this context.
