1. An Interaction Abstraction Toolkit for Public Display Applications Jorge C. S. Cardoso jorgecardoso@ieee.org http://jorgecardoso.eu
2. Outline • Motivation • Objective • Challenges • Interaction Abstractions • Evaluation • Conclusion
3. Motivation: “We need to do better”
4. Motivation Each display uses its own approach to interactivity
5. Objective: Interaction abstractions for public displays “toolkits for novel and perhaps unfamiliar application areas enhance the creativity of these programmers. By removing low-level implementation burdens and supplying appropriate building blocks, toolkits give people a ‘language’ to think about these new interfaces, which in turn allows them to concentrate on creative designs.” - Greenberg, S. (2007). Toolkits and interface creativity. Multimedia Tools and Applications, 32(2), 139–159.
6. Interaction in public displays Focus • Generic information displays • Multi-user • Shared environment • Multiple input devices
7. Interaction in public displays Challenges • Very different interaction environment ◦ What kind of abstractions are useful? • No accepted interaction paradigms ◦ No accepted set of “controls” • Variety of interaction mechanisms
8. SMS
9. QR Codes
10. Gestures
11. Bluetooth
12. Touch
13. Keyboard + trackball!
14. What kind/level of abstractions? • Footprints for socially-aware display systems ◦ Designers • User Interaction Controls ◦ Developers
15. Footprints for socially-aware display systems What information can the display gather from interactions that can be used for context-aware content adaptation? Focus on adaptation to the social situation around the display Abstract interaction mechanisms and application semantics

23. Conclusion: Summary of contributions 1. A framework of digital footprints that designers of public displays can use to map several sensing and interaction features to content adaptation strategies. 2. A design space of interaction tasks and controls that can serve as a basis for programming toolkits that provide high-level interaction widgets. 3. Identification of the fundamental requirements for an interaction abstraction toolkit for public displays. 4. The PuReWidgets software toolkit itself for incorporating interactive features into public display applications 5. An in-breadth evaluation of the PuReWidgets toolkit along several dimensions, including the system’s performance and scalability, the API usability, and a real-world deployment. 6. Open-source software projects, allowing anyone to use, modify, and adapt for further research and development. • https://code.google.com/p/purewidgets/ i. – The PuReWidgets toolkit . ii. – Three interactive public display applications • https://code.google.com/p/public-display-scheduler/ A Google Chrome extension that serves as an application scheduler for public displays.

25. Conclusion • We need better tools to create applications for open display networks ◦ Interaction abstractions • PuReWidgets is just one attempt/model
