Open public display networks
● Open display networks○ "designed and implemented to be open to
applications and content from many sources and thus provide the foundation for work on a new global communications medium for information access and interaction”
Interaction toolkit for public displays
● Different displays may provide different interaction capabilities
● Developers need ○ Abstraction from interaction mechanisms○ Various high-level controls
PuReWidgets
● High-level abstractions○ Widgets
● Independence from interaction mechanism○ SMS○ Email○ Touch○ Mobile interface○ QR code
Widgets
Interaction
Touch Text-based (SMS, email, …)
QR codes Mobile interface(Automatically generated)
Automatic GUI for mobile devices
● Discoverability○ Of apps○ Of apps’ features
● Interaction
● No extra effort for programmers of public display apps
Dynamic GUI generation approaches
● Downloadable UI code○ e.g., Jini Service UI
● Abstract UI description○ XWeb (Olsen et al., 2000)
● Hybrid○ Hodes & Katz, 1999 ○ iCrafter (Ponnekanti et al., 2001)

Preliminary evaluation
● Real-world deployment
Discussion
● Asynchronous interaction
● Rapidly changing widgets
Conclusion
● We need better tools to create applications for open display networks
○ Interaction abstractions
● PuReWidgets is just one attempt/model
