Human activities have drastically altered the planet, with design playing a significant role. While design may intend to do good, its consequences are not always positive: from climate change to resource depletion to unforeseen social dynamics. These transformations also include ourselves, as our relationships with new technologies blur and complicate previous human and machine agency distinctions. Increasingly, design has become a matter of defining what it means to be human. This special issue explores the proposition that conventional human-centered design approaches may not adequately address the complex challenges we face, and that there is instead a need to ground design in more-than-human perspectives. This introduction outlines the evolving landscape of more-than-human design in the context of HCI. Articulating a series of emerging research trajectories, we aim to illuminate the transformative potential of more-than-human orientations to design, including how they both extend and depart from familiar lines of inquiry in HCI – for example, how designers are redefining data, interfaces, and responsibility, and reshaping posthuman knowledge through design. Ultimately, this special issue aims to explore new pathways for designing in the era of the more-than-human, challenging the perceived divide between practice and theory to imagine alternative futures for HCI.

Seen both as a resource and an obstacle to clarity, uncertainty is a concept that permeates many areas of design. As the concept gains prominence in Human-Computer Interaction (HCI), this special issue specifically explores the interplay between uncertainty and prototyping in Research through Design (RtD). We first outline three histories of uncertainty in design, in relation to its philosophical significance, its role in statistical and algorithmic processes, and its importance in prototyping. The convergence of these aspects is crucial as design evolves toward more agentive and entangled systems, introducing challenges such as Design as a Probabilistic Outcome. We then investigate the design spaces for engaging with “being uncertain” that emerge from the papers: from nuancing the relationship between designers and quantitative data to blurring the line between humans, fungi, and algorithms. Finally, we illuminate some preliminary threads for how RtD can navigate and engage with these shifting technological and design landscapes thoughtfully.

This article explores the intersections and resonances between unmaking and more-than-human design. We begin by aligning unmaking with decentering, a fundamental practice in more-than-human design, through their shared movement and materiality. Using Lindström and Ståhl’s notion of the double movement in un/making, we analyze a series of workshops focused on designing with AI, annotating what was un/made and de/centered during the workshops’ activities. Through this analysis, we introduce two key contributions that highlight some opportunities in the diffractive alignment between unmaking and more-than-human design: firstly, the notion of “unmaking-with” as an emergent concept to describe a posthumanist unmaking practice, and secondly, three decentering tactics—situating, materializing, and enacting—that instantiate this practice through design. Finally, we discuss how unmaking can enrich more-than-human design and, conversely, how more-than-human design can help define the epistemological scope of unmaking.

This paper presents a design exploration of opportunities for opening up industrial infrastructures in order to make them supportive of more sustainable and locally adaptive configurations. Taking logistic services in a rural area as a case study, we describe a set of interventions in tracing and expressing their underlying functionalities to make them available as design material. The insights gained inspired the speculative design of a concept for a distributed and community-owned delivery network performed by drones. The case illustrates the potential that can be made available when opening up infrastructures for participative design interventions.

This is an analysis and exploration of a basic aesthetic issue in interaction design: how an ambition to design strong and persistent relations between appearance and functionality, evident in approaches such as tangible user interfaces, in crucial ways in which conflicts with the ways miniaturization of technology have changed the relation between the object's surface and its internal complexity. To further investigate this issue, four conceptual design experiments are presented exploring the expressiveness and aesthetic potential of overloading the object's surface by adding several layers of interaction, thus creating a kind of tangled interaction.

Computational composite is introduced as a new type of composite material. Arguing that this is not just a metaphorical maneuver, we provide an analysis of computational technology as material in design, which shows how computers share important characteristics with other materials used in design and architecture. We argue that the notion of computational composites provides a precise understanding of the computer as material, and of how computations need to be combined with other materials to come to expression as material. Besides working as an analysis of computers from a designer's point of view, the notion of computational composites may also provide a link for computer science and human-computer interaction to an increasingly rapid development and use of new materials in design and architecture.

The coming ubiquity of computational things urges us to consider what it means for something to be present in someone's life, in contrast to being just used for something. "Use" and "presence" represent two perspectives on what a thing is. While "use" refers to a general description of a thing in terms of what it is used for, "presence" refers to existential definitions of a thing based on how we invite and accept it as a part of our lifeworld . Searching for a basis on which these existential definitions are formed, we argue that the expressions of things are central for accepting them as present in our lives. We introduce the notion of an expressional , referring to a thing designed to be the bearer of certain expressions, just as an appliance is designed to be the bearer of a certain functionality. Aesthetics, as a logic of expressions, can provide a proper foundation for design for presence. We discuss the expressiveness of computational things as depending both on time structures and space structures. An aesthetical leitmotif for the design of computational things---a leitmotif that may be used to guide a normative design philosophy, or a design style---is described. Finally, we describe a practical example of what designing a mobile phone as an "expressional" might be like.

We describe WEST, a WEb browser for Small Terminals, that aims to solve some of the problems associated with accessing web pages on hand-held devices. Through a novel combination of text reduction and focus+context visualization, users can access web pages from a very limited display environment, since the system will provide an overview of the contents of a web page even when it is too large to be displayed in its entirety. To make maximum use of the limited resources available on a typical hand-held terminal, much of the most demanding work is done by a proxy server, allowing the terminal to concentrate on the task of providing responsive user interaction. The system makes use of some interaction concepts reminiscent of those defined in the Wireless Application Protocol (WAP), making it possible to utilize the techniques described here for WAP-compliant devices and services that may become available in the near future.
