“Pengi: An Implementation of a Theory of Activity”
Pengi
(Agre & Chapman, 1987)
AI has generally interpreted the organized nature of everyday activity
in terms of plan-following. Nobody could doubt that people often
make and follow plans. But the complexity, uncertainty, and
immediacy of the real world require a central role for
moment-to-moment improvisation. Before and beneath any
planning ahead, one continually decides what to do now.
Investigation of the dynamics of everyday routine activity reveals
important regularities in the interaction of very simple machinery
with its environment. We have used our dynamic theories to design
a program, called Pengi, that engages in complex, apparently-planful
activity without requiring explicit models of the world.

Pengi uses “indexical-functional aspects”
