ShineUS: Exploring preferences in public discussion

We propose to demonstrate a system for discussing posters. The system bridges the physical and virtual, using QR codes to tag posters and being available through mobile devices, the web and a projection or large screen view. Control over visibility of interactions is provided, allowing users to control their exposure and consider privacy concerns while making comments on a per-post basis. The use of identity, integration with Facebook and Twitter, ability to reply and ongoing availability of the system after the conference all allow it to take on a social aspect. The deployment will contribute to our research by providing further data on how such systems, in particular their visibility controls, are used.
