As artificial intelligence (AI) automates technical and dialogic processes, technical communicators produce value through articulating complex problems, facilitating new forms of participation, and managing user-generated content via experience architecture. Automated and intelligent agents are least able to grasp the context of experiences, requiring human input/feedback for maximum performance. The examples we trace both prepare communities to embrace AI as part of the available information infrastructure and create an automated infrastructure of intelligent augmented action. Following Star's anthropological investigation of infrastructure, we analyze organizational examples where rhetoric entangles AI, automation, generative design, additive manufacturing, gift labor, and assembly lines.

Traversing public and private spaces inevitably means finding a way to access those spaces. This simple fact is thrown into relief for those who experience barriers to access, and often unnoticed by those whose bodies, minds, abilities, and resources allow them to occupy the role of default user. Multimodality has been discussed at length as a means to enhance access to the public and private spaces through which we and our writing move. However, we argue that multimodality as it is commonly used implies an ableist understanding of the human composer. Our webtext seeks to redress this problem.

The hype machine---media, corporate communications, and futurist prognosticators---are hard at work promoting Big Data. There are computing and storage resources that, like the "dark fiber" installed at the turn of the millennium that now carries streaming video, are looking for huge data sets that require the powerful processing and tremendous storage capacity of the new infrastructure. And there is no better confluence than that provided by the impetus to rearticulate Communication Design Quarterly in an age of Big Data. The New York Times has been running articles about Big Data for some time: "Big data is all about exploration without preconceived notions."

Recently, human and user-centered design methods have challenged older system-centered practices, enriching resources and providing better technological artifacts for end-users. This article argues that though design has become more user-centered, something is still lacking: more opportunities exist for articulating feedback already present in technology-culture networks. To encourage the recovery of this feedback, this article examines discourses surrounding transportation technology and the Chōra, the variety of stakeholders who shape the progression of technology through use, negation, or re-appropriation. While this article is far from a programmatic or procedural document, it suggests opening design processes to a variety of cultural inputs beyond those marked as “users.” It attempts to open a space for technical communicators in these multifaceted feedback loops, where Chōral influences are articulated and rearticulated for more effective transportation design.

Twenty years after the publication of Patricia Sullivan's ldquoBeyond a narrow conception of usability testingrdquo in the IEEE Transactions on Professional Communication, three scholars - all Sullivan's students - reflect on the history and development of usability testing and research. Following Sullivan, this article argues that usability bridges the divide between science and rhetoric and asserts that usability is most effective when it respects the knowledge-making practices of a variety of disciplines. By interrogating trends in usability method, the authors argue for a definition of usability that relies on multiple epistemologies to triangulate knowledge-making. The article opens with a brief history of the development of usability methods and argues that usability requires a balance between empirical observation and rhetoric. Usability interprets human action and is enriched by articulating context and accepting contingency. Usability relies on effective collaboration and cooperation among stakeholders in the design of technology. Ultimately, professional and technical communication scholars are best prepared to coin new knowledge with a long and wide view of usability.

This article focuses on information architecture as a site for developing critical practice for technical communication. Such a focus suggests methods for rhetorical intervention aimed at democratizing the process of technocultural development. As a site of intervention, information architecture invites practitioners and academics to develop plans for action based on the analysis generated in descriptive research, completing the circuit from analysis to informed action.

This article proposes a model for critically engaging technology in technical communication graduate curricula. While computers and writing studies concentrates on academic writing, the development of the field provides a model for engaging technological issues in professional and classroom contexts. Technical communicators have an ethical as well as intellectual responsibility to engage the interface between technology and culture. This article describes one example, a graduate class in information architecture, as a model for engaging the nexus of literacy, technology, and culture.

Abstract This article explores the shift from observation of users to participation with users, describing and investigating three examples of user-centered design practice in order to consider the new ethical demands being made of technical communicators. Pelle Ehn's participatory design method, Roger Whitehouse's design of tactile signage for blind users, and the design of an online writing program are explored for the creation of a dialogic design ethic. The development of effective collaborative design methods requires meaningful communication between users and designers, and dialogic ethics can guide the development of effective and humane technological design methods.
