2. Mo5va5ons
• Contexts

Use
vary
– User

– PlaHorms
– Environments
• One-­‐size-­‐does-­‐not-­‐fit-­‐all
• (Manually)
Implemen5ng
dedicated

– Neither
feasible
– Nor

Mo5va5ons
• Heterogeneous
contexts
of
use
– User,
plaHorm,
environment
• No
standard
approaches
– Terminology,
framework,
support
tools
• Need
for
adapta5on

5. 5
Heterogeneous
contexts
of
use

6. No
standard
approaches
• Current
solu5ons
– Several
approaches
– No
unified
solu5on
– Inconsistencies
– Incompa5bility
– Incompleteness
– Obsoleteness
– Ambiguous
terminology

7. Fundamental
Concepts
• Context-­‐awareness
• Adapta5on
• Framework
– Meta-­‐Model
– Reference

– Cards
– Design

State-­‐of-­‐the-­‐Art
• Several
works
– Since
early
90’s
• Scacered
informa5on
sources
• Narrowed
focus
– Technology
dependent
– Context
constrained
– Domain
specific

9. 9
Exis5ng
Meta-­‐Models
• Rules
– Adapta5on,
transforma5on
– Condi5ons,
quali5es
• Context:
percep5on,
reac5on,
learning
– User
– PlaHorm
• Mobile
– Task
– Domain

TriPlet
Benefits
• Designer
and
Developer
– Alterna5ves
for
design
decisions
– Standard
Framework
enabling
instan5a5ons
– Unified
terminology
• End

– Quali5es
– Completeness
– More

Conclusion
• One-­‐size-­‐does-­‐not-­‐fit-­‐all
• Adapta5on
is
needed
• So
far,
not
enough
support
– Unified,
integrated,
complete
• TriPlet
– Extensible
– Flexible
– Generic
Purpose
• Technology-­‐independent
• Domain-­‐independent
