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

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.
