Participation & Affordances

LCC 2700: Intro to Computational Media

Borges Forking Paths

A book that is a labyrinth

An action that is a coded message

A view of human life and the meaning of our choices

Borges Forking Paths

Fictional exploration of philosophy

A stable genre: the detective stories- clues and puzzles => solution

Time branches into infinite futures

Space - Time- conceptual space- time as space

A Novel that can be read in multiple ways

The book/maze of Ts’ui Pen

Everything is possible, and everything occurs in some reality

Agency

• What does it mean to be “active” in a computational environment or system?

Postmodernism / Poststructuralism

• Structuralism– The study of fundamental elements that constitute higher

order structures– Humanistic movement of the 19th and 20th c.– Linguistics (Ferdinand de Saussure)

• the system over the use of language• Fundamental linguistic structures• Semiotics• Linguistic signs = signifier/signified

– Anthropology (Claude Lévi-Strauss)• Fundamental mental structures• Cultural phenomena: mythology, kinship

– Literary studies• The structures or formulas for literary production

Postmodernism / Poststructuralism

• Poststructuralism– A response to structuralism – Intended to unseat the former’s intention to craft absolutist,

top-down understandings of cultural systems– No generalizable meta-language is sufficient to understand

human experience– Poststructuralists believe such experiences are culturally

situated and can only be understood in light of such contexts– Psychoanalysis (Jacques Lacan)– History (Michel Foucault)– Literature (Jacques Derrida, Roland Barthes, etc.)– Philosophy, art (Gilles Deleuze, etc.)

The Rhizome

• Concept from Deleuze & Félix Guattari’s A Thousand Plateaus• One of many poststructuralists models or analogies for

artistic/literary production and consumption• Rhizome: from botany

– An underground stem or root system that extends new shoots from its nodes

– In contrast to the branching root system, the rhizome symbolizes arbitrary growth

• Deleuze and Guattari borrow this term for todescribe literary, artistic, and cultural practicesthat allow for non-hierarchical movement withinsystems of meaning

• Any point connects to any other; a part of a muchlarger theoretical framework

Relationship to Literature and Art

• “Free play” in a signifying system engenders multiple meanings

• Notion of artifacts as “texts” to be read in a variety of contexts

• De-emphasis of the intention and role of the author– “Death of the Author” by Roland Barthes

• New emphasis on the role of the reader/viewer/etc.– Texts as co-produced by the author and the

reader• Rhizome as one way to characterize this free play• “Rhizome” is borrowed heavily in hypertext theory

and practice• Hypertext and “new media” as “realizations” of

poststructuralism

Problems with the Rhizome

• Practically, the notion that “anything is possible” is not so productive, perhaps even impossible– Texts can be read creatively– Computational systems?

• Janet Murray, “the rapture of the rhizome”– “unheroic and solutionless”– Postmodernists “privilege confusion” over

representation, liberation from the “tyranny of the author”

• Solution: A return to intentional experiences: design for intended, but open effect

Can you really “do anything you want”?Would you want to?

Participation as Structured Expereince

Constraints structure the possibility space of experiences

Constrained action

Computational expressive artifacts as goal-directed works with constrained action

Constraint produces and structures expression

Don Norman, The Design of Everyday Things

• Well-known computer scientist• VP at Apple, “Human-centered products”• Partner, Nielsen-Norman Group (with Jakob

Nielsen)• “The Andy Rooney of design”

Norman’s design principles

• Conceptual Models - the way human minds find meaning in things

• Affordances - “appropriate actions are perceptible, inappropriate ones are invisible”– Jointly determined by environment and

organism• Constraints - limits to choices• Feedback - showing the effects of an action

Norman’s design principles

• Mostly interested in physical and cognitive affordances

• And perceived affordances in particular

• Determinsm? Free-play? Expression?

Determinism? Free play? Expression?
