Four eras of human–technology relations, mapped completely.
From Card, Moran & Newell's cognitive user to Frauenberger's entangled configuration. The methods that defined each era, the outcomes they produced, the lenses they privileged, and the assumptions each one preserved until the next era broke them.
Methods, outcomes, lenses, anchors, every era, every dimension.
Read top-to-bottom by dimension to see how a single question (e.g., "what is the unit of study?") evolves across forty years. Read left-to-right by era to see how each era's pieces hung together. The transition bands between row groups show what assumption broke and what assumption took its place.

|---|---|---|---|---|
| A · Orientation of the era | ||||
| Dominant paradigmWhat kind of research is HCI? |
Engineering / cognitive science
HCI as the application of cognitive psychology to computer use. Goal: predict and reduce user error.
|
Ethnography / social science
HCI as the study of work practice in context. Goal: design that fits situated activity.
|
Design discipline / humanities
HCI as a design field engaging culture, emotion, aesthetics. Goal: experiences that matter.
|
Post-disciplinary / entangled inquiry
HCI as the study of configurations in which humans, AI, and context co-constitute each other. Goal: legibility of what is being enacted.
|
| Unit of studyWhat is the analytic object? |
The user
A bounded cognitive system with measurable properties, memory, attention, reaction time, error rate.
|
The user-in-context
A practitioner embedded in workflow, organization, and community of practice. A situated actor.
|
The experiencing subject
A cultural, emotional, embodied person who makes meaning from designed encounters.
|
The configuration
A material-discursive arrangement of humans, AI, and context whose components do not pre-exist their relations.
|
| B · Methods & design stance | ||||
| Canonical methodThe signature probe |
Think-Aloud Protocols
Lab-based usability testing. Verbalized cognition while performing tasks. Heuristic evaluation.
Ericsson & Simon 1984 · Nielsen 1994
|
Contextual Inquiry
Workplace observation, master-apprentice interviewing, work models, activity analysis.
Beyer & Holtzblatt 1998 · Engeström 1987
|
Cultural Probes
Designer-made artifacts deployed for evocative, fragmentary returns. Autoethnography. Design fiction.
Gaver, Dunne & Pacenti 1999 · Boehner et al 2007

Rivera 2023 · Rivera & Russi 2026 (under review)
|
| Design stanceHow designers position themselves |
Human Factors / Ergonomics
Designer as engineer optimizing the human-machine fit. The user is a system component with specs.

Participatory / User-Centered Design
Designer as facilitator of co-design with users. The workplace as collaborator.

Design Thinking / Critical Design
Designer as empathic translator and as cultural provocateur. Two strands: convergent (IDEO) and critical (Dunne & Raby).
Brown 2009 · Dunne & Raby 2013
|
Configurational / Posthuman Design
Designer as configurer of distributed intelligences; deliverable is diagnostic visibility (the X-ray) of an ephemeral configuration.
Forlano 2017 · Frauenberger 2019
|
| C · Outcomes the era produced (across four lenses) | ||||
| HCI outcomeWhat design produces |
Usability
Efficient, learnable, error-resistant interfaces. Performance benchmarks.
Nielsen 1993
|
Workflow & task fit
Systems that fit organizational practice. CSCW, groupware, contextual design outputs.
Suchman 1987 · Bødker 1991
|
User Experience (UX)
Felt arc of an encounter, usability plus aesthetics, emotion, meaning. The category Norman coined.
Norman 1993 · McCarthy & Wright 2004
|
Constitutive Identity
What the human-AI configuration is making the person become, continuously, in change, identity-level.
Frauenberger 2019 · Forlano 2017 · Schrage 2020
|
| Persuasive Tech parallelWhat computing does to/with people |
Behavioral instrumentation
Pre-Fogg. Behaviorist tradition; Skinner-influenced reinforcement learning systems.
Skinner lineage
|
Computers as Social Actors
CASA paradigm. People respond to media as if they were people. Anthropomorphism research consolidates.
Reeves & Nass 1996
|
Persuasive Technology (Captology)
Fogg's field. Tool / Medium / Social Actor triad. B = MAT model. Behavior change as design goal.
Fogg 1998, 2003
|
Constitutive Technology
Wave-4 update of Persuasive Tech. Practice / Cognition / Identity triad. Tech constitutes rather than persuades.
Verbeek 2011 · Schrage 2020 · this lab
|
| Organizational frameHow orgs understand themselves |
Scientific management residue
Taylor-era logic still dominant; computers as productivity instruments. MIS / DSS emerging.
Davis 1989 (TAM)
|
Learning Organization / KM
Senge's systems-thinking org. Knowledge management. Business Process Reengineering. Communities of practice.
Senge 1990 · Nonaka 1995 · Lave & Wenger 1991
|
Digital Transformation
Service-Dominant Logic. Customer Experience (CX). Platform organizations. Agile. The 4IR / Fourth Industrial Revolution framing.

Constitutive Configuration
Algorithmic isomorphism. CAS-thinking organizations. Dynamic adaptive capability. The Coherent Organization as continuous calibration practice.

| STS analytic objectThe unit of analysis in STS |
SCOT (emerging)
Social Construction of Technology. Interpretive flexibility. Relevant social groups shape technology.
Pinch & Bijker 1984

Actor-Network Theory (codifying)
ANT consolidates. Translation, inscription, enrollment. Humans and nonhumans symmetrically actors.
Callon 1986 · Akrich 1992 · Latour 1992
|
Material semiotics / posthumanism
Haraway's influence widens. Material-semiotic methods. Critical posthumanism enters HCI / design.
Haraway 1985 · Suchman 2007 · Law 2004
|
Configurational Becoming
Agential realism. Entities do not pre-exist their relations. Intra-action replaces interaction. Configurations as the unit.

| What the era assumed | that a stable user has cognitive properties measurable in lab conditions | that work practice is observable through ethnography in context | that experience happens to a pre-formed subject who makes meaning from designed encounters | (we are still inside this era, its core assumptions are still being articulated) |
| What broke the era | real-world contexts do not match laboratory conditions | embodied, emotional, cultural dimensions are not visible to workplace ethnography alone | AI configurations dissolve the user/technology distinction. Experience is no longer something a finished subject has | (the era is open) |
What changes across all four eras, and what stays constant.
The eras are not just successive vocabularies, they are successive answers to a smaller set of questions that the field keeps asking. Below: the three through-line questions, traced.
Era 1: the laboratory.
Era 2: the workplace.
Era 3: the cultural-emotional encounter.
Era 4: the configuration itself, knowledge is generated through the intra-action that produces both observer and observed. The X-ray is valid only for the moment of its taking.
Era 1: a cognitive processor.
Era 2: a situated practitioner.
Era 3: a cultural-emotional subject.
Era 4: there is no user. There is a configuration that produces human and machine positions through the activity. "User" is a wave-three category preserved in wave-four work only as a methodological convenience.
Era 1: efficient interfaces.
Era 2: contextually fit workflows.
Era 3: experiences and provocations.
Era 4: diagnostic visibility. Design produces X-rays of ephemeral configurations, and the practice of re-X-raying as configurations continuously become.
