16
Q

Distributed cognition as a lens

A

Way of looking at interface design

Q

Situated action

A

Easier to recall than remembering from scratch
The context of the task makes the task more remember
Plans are interpretations of actions
We forget the history of the plan of task

20
Q

Activity theory

A
  • Why is the user performing the task
  • Low level operators to accomplish high level actions
  • Activity theory moves the action up and down the heirarchy

Study of context situation and practice

Activated. Theory + distributed cognition+ situated action
Activity theory + distributed cognition are diffrenet-belifebin artifacts and human consciousness

21
Q

Interface and politics

Some interface are to create change in the world
Design for change
