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
