2. 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”

3. Interaction toolkit for public displays
● Different displays may provide different
interaction capabilities
● Developers need
○ Abstraction from interaction mechanisms
○ Various high-level controls

4. PuReWidgets
● High-level abstractions
○ Widgets
● Independence from interaction mechanism

5. Widgets

6. Interaction
Touch
Text-based
(SMS, email, …)
QR codes
Mobile
interface
(Automatically
generated)

7. Automatic GUI for mobile devices
● Discoverability
○ Of apps
○ Of apps’ features
● Interaction
● No extra effort for programmers of public
display apps

8. 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)

18. Preliminary evaluation
● Real-world deployment

19. Discussion
● Asynchronous
interaction
● Rapidly changing
widgets

20. Conclusion
● We need better tools to create applications
for open display networks
○ Interaction abstractions
● PuReWidgets is just one attempt/model

21. Thank you!
