Outline

● Motivation● Objective● Challenges● Interaction Abstractions● Evaluation● Conclusion

Motivation: “We need to do better”

Motivation

Each display uses its own approach to interactivity

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.

Interaction in public displays

Focus● Generic information displays● Multi-user● Shared environment● Multiple input devices

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

SMS

QR Codes

Gestures

Bluetooth

Touch

Keyboard + trackball!

What kind/level of abstractions?● Footprints for socially-aware

display systems○ Designers

● User Interaction Controls○ Developers

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

Conclusion: Summary of contributions1. 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 applications5. 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.
