Week 10 Distributed Cognitive Systems
Why Distribute Cognition
Tasks are just too hard
Do not want to depend on a single individual
-check for errors
-they may quit!
-shift changes
Need to coordinate tasks done my many individuals
Tasks require coordination across space and time
It is part of the fun! (social software, games)
Need for New HCI Methods
Much of HCI, information design came from studies and design experience with traditional
computer displays
We must design increasingly complex interactive displays that can be perceived and understood
by users
Multiple displays and input methods may be used
Communication and collaboration (same/different place, time) may be needed
-application goals may be cognitive, social, or experiential
When visual intelligence end & intelligence begin
Cognitive impenetrability (Pylyshyn, 1984) refers to the inability of observers to use semantic
information (such as what the person believes or intends to do) to influence the operation of
the input stage
Modularity of Mind (Fodor, 1980) argues that information is hidden (encapsulated) in modules
and cannot be shared

Major Claim 1: Thinking as smart seeing and Projecting
Actively looking at external representations and projecting onto them makes us more powerful
thinkers than thinking in our heads alone
