ALAF01: 1st International Workshop on Algorithmic Affordances in Recommender Interfaces

In conjunction with INTERACT 2023
York 28 August - 1 September 2023

Algorithms play a significant role in our daily lives, making decisions for users on a regular basis. This widespread adoption necessitates a thorough examination of how users interact with algorithms via interfaces, particularly in the context of recommender systems. The design of a recommender’s interface and specifically its algorithmic affordances have a serious impact on the user experience. Algorithmic affordances are mechanisms in the interface of recommender systems, that allow users tangible control over the algorithm. A straightforward example of an algorithmic affordance is ‘feeding the algorithm’, where the user specifically provides data to the algorithm to influence subsequent recommendations. Examples of implementations of ‘feeding the algorithm’ are rating and blacklisting. Other algorithmic affordances are, for instance, explanations, or allowing a user to manipulate parameters, in a way that shifts the recommendations’ original prominence..

For recommender interface design, it is crucial to understand how algorithmic affordances impact interaction qualities such as transparency, trust, and serendipity, and as a result, the user experience. Currently, the precise nature of the relation between algorithmic affordances, their implementation in recommender interfaces, interaction qualities, and user experience remains unclear. Consequently, much is still to be explored in this domain; furthermore, designers are largely without guidance when making design choices on algorithmic affordances in their algorithm-driven design projects. In response, this one-day workshop aims to bring together designers and researchers, providing a platform to exchange insights, research findings, design experiences, and knowledge on these complex interrelationships. The concluding segment of the workshop will focus on exploring the feasibility of a prospective tool designed to facilitate collaboration between designers and researchers in this field to aid both research and design practice. 

- the user’s experience of increased control provided by algorithmic affordances 
- mental model construction signalled by algorithmic affordances  
- design patterns of algorithmic affordances  
- balancing algorithmic affordances & cognitive overload 
- how interface elements signal the presence of algorithmic affordances 
- the relationship between algorithmic affordances and various interaction qualities 
- general principles of the relationship between algorithmic affordances, interaction qualities and user experience 
- a practitioner’s hands-on experience with designing algorithmic affordances in a recommender’s interface 
- means to have fundamental research results on algorithmic affordances in recommender interface design land in the design practice

We invite both researchers and designers to submit papers and/or relevant examples. We will reserve a limited amount of spots for participants who did not submit a paper but for whom the topic is relevant. 


We aim for the following outcomes

- collected insights on how algorithmic affordances affect user experience
- increase understanding of the relations between algorithmic affordance, interaction qualities and user experiences in recommenders' interfaces
- a shared perspective of researches and designers
- preliminary guiding principles for the development of a pattern library on algorithmic affordances


We invite ux/ui-designers, researchers into HCI and HAII, and AI engineers working on topics or designs related to recommender interfaces  to submit original papers of the following kinds: 

- research papers describing recent results, user studies, literature reviews 
- statements of interests or position papers describing novel ideas or perspectives 
- case studies of interfaces including algorithmic affordances designed by the submitter, including a rationale of the decisions regarding algorithmic affordances and interaction qualities
- case studies of recommender interfaces encountered by the submitter, that sparked ideas or considerations on algorithmic affordances and interaction qualities in recommenders 
- short statements of interest for those who do not wish to hand in a paper, but still would like to participate in the workshop (a limited number of spots will be reserved)

All submitted should represent original and previously unpublished work currently not under review in any conference or journal. Papers, submitted design examples , and statements of interest will be peer-reviewed and selected by relevance and likelihood of stimulating and contributing to a discussion related to the workshop theme.  Should for the discussions of examples an NDA for participants be needed, that can be taken under consideration.

- The maximum length for papers is 6 pages, use springer format including references and a 300 word abstract. Shorter submissions are also welcome. 
- When submitting an example of a design, please use the abstract to explain the context of the design and the prime reason for its relevance for this workshop, and use the file to provide clear visual material of the interfaces as far as that is possible without breaching confidentiality agreements. Maximum length, here, too is 6 pages.
- When submitting a statement of interest, please use the abstract to make your interest known and elaborate on it a bit. You may use the file to submit e.g. a list of previous research, a recent relevant paper that you have written, but that has been published already or is under review, or an updated cv, so we can ensure an engaged and active group of participants

Please submit your paper electronically to href="
Springer templates for submission:  a href=" (Word) or or" (LaTeX)

Submitters of accepted contributions (paper or case study) or requests for participation must guarantee their presence at the workshop (or send an representative). Accepted work, both papers and design examples, will be published in a volume dedicated to the proceedings of this workshop. 

Important Dates

- May 5, 2023:  deadline submission of position papers to workshops 
- May 20, 2023:  Notification to submitters of papers and examples
- To be announced: Data of end of early bird registration 
- August 28 – September 1st:  Interact 2023

Deadlines are AoE.
