attempt to cope• Information visualization: make
sense of abundance

Brains crave patterns
• A pattern is
– About sense making– Understanding– Temporary “state of”– Evolving, emergent– Aggregation, context, experience

Current state
• Information generation tools – exploded
• Aggregation tools – growing
• Data, information manipulation tools: embryonic

• Grunt cognition• Move to meaning/sensemaking • Shifts perspectives• Provides insight• Memory• New connections

Sensemaking
• What is it?• What does it mean?• What perspectives are included?• Shared?

Networks & Ecologies
• Filter• Foster• Form patterns• Create archive “future repurposing”

Yeah, ok, but what’s the use?
• Network models of learning are adaptive
• Ecologies must be diverse and enabling• Today’s information is tomorrow’s
sensemaking• Sane, digital life• Complex, integrated understanding• Multi-faceted• Multi-ontology
