Towards a pattern library for algorithmic affordances

The user experience of our daily interactions is increasingly shaped with the aid of AI, mostly as the output of recommendation engines. However, it is less common to present users with possibilities to navigate or adapt such output. In this paper we argue that adding such algorithmic controls can be a potent strategy to create explainable AI and to aid users in building adequate mental models of the system. We describe our efforts to create a pattern library for algorithmic controls: the algorithmic affordances pattern library. The library can aid in bridging research efforts to explore and evaluate algorithmic controls and emerging practices in commercial applications, therewith scaffolding a more evidence-based adoption of algorithmic controls in industry. A first version of the library suggested four distinct categories of algorithmic controls: feeding the algorithm, tuning algorithmic parameters, activating recommendation contexts, and navigating the recommendation space. In this paper we discuss these and reflect on how each of them could aid explainability. Based on this reflection, we unfold a sketch for a future research agenda. The paper also serves as an open invitation to the XAI community to strengthen our approach with things we missed so far.

Exploring Categorizations of Algorithmic Affordances in Graphical User Interfaces of Recommender Systems

This exploratory study investigates the rationale behind categorizing algorithmic controls, or algorithmic affordances, in the graphical user interfaces (GUIs) of recommender systems. Seven professionals from industry and academia took part in an open card sorting activity to analyze 45 cards with examples of algorithmic affordances in recommender systems’ GUIs. Their objective was to identify potential design patterns including features on which to base these patterns. Analyzing the group discussions revealed distinct thought processes and defining factors for design patterns that were shared by academic and industry partners. While the discussions were promising, they also demonstrated a varying degree of alignment between industry and academia when it came to labelling the identified categories. Since this workshop is part of the preparation for creating a design pattern library of algorithmic affordances, and since the library aims to be useful for both industry and research partners, further research into design patterns of algorithmic affordances, particularly in terms of labelling and description, is required in order to establish categories that resonate with all relevant parties

The affective affordances of disability

In this paper, I propose an affective-formalist reading of what I call the affective affordances of disability; the way in which the representation of disability is able to move us. Through a comparative reading of two artworks, Michelangelo's David and Berlinde de Bruyckere's Into One-another Ill, to P.P.P., this paper explores the relationship between how reading for form in the mimetic representation of disability informs how we are affected by it. Concurrently, it explores how affect, conceived as a visceral force that moves through and impresses on bodies, can be generated through the way in which disabled bodies are represented in art.

Regimes of visibility and the affective affordances of Twitter

Online social networks produce a visuality that reflects the attention economy governing this space. What is seen becomes elevated into prominence by networked publics that ‘perform’ affective expressions within platform affordances. We mapped Twitter images of refugees in two language spaces - English and Arabic. Using automated analysis and qualitative visual analysis, we found similar images circulating both spaces. However, photographs generating higher retweet counts were distinct. This highlights the impact of affective affordances of Twitter — in this case retweeting — on regimes of visibility in disparate spheres. Representations of refugees in the English language space were characterized by personalized, positive imagery, emphasizing solidarity for refugees contributing to their host country or stipulating innocence. Resonating images in the Arabic space were less personalized and depicted a more localized visuality of life in refugee camps, with an emphasis on living conditions in refugee camps and the efforts of aid organizations.

Psychological ownership affordances as routes to influence product lifetime

Extending the lifespan of products can be approached in several ways. One promising way is to give users a greater sense of ownership of the products that are used. In the context of Product Service Systems (PSS), products are often used temporarily, shared with others, and offered through a technology-mediated environment. Not much is known about psychological ownership in this context. To evaluate psychological ownership affordances as an intermediate knowledge tool in the context of PSS, we started a case study focused on a bicycle sharing service of The Student Hotel (TSH). The central question was how a design approach, based on psychological ownership, can help to redesign the bicycle-service of TSH to contribute to extended lifespans of the bicycles. This resulted in ten exemplary designs as project outcomes and two implemented design interventions in a TSH branch. All project members and stakeholders (app supplier X-bike and Roetz-bikes mechanics) and students of Eindhoven University of Technology (TU/e) and Utrecht University of Applied Sciences (HU) (n=42) were interviewed on process efficiency, process quality and design quality at the end of the collaboration. We performed a qualitative analysis to identify when and how the team members applied the design tool, how these obstructed or supported the design process, and if the team members show shared understanding of the behavioral and/or social consequences of their decisions. The results show both top-down and bottom-up insights, leading to four suggestions for adapting the existing model as an intermediate knowledge tool: (1) being more goal-oriented, (2) consider a hierarchy of affordances, (3) consider to add a new affordance and (4) recognize a more active role of the service provider.
