Abstract
Carousel-based interfaces are integral in enhancing user experience in online recommender systems like streaming services or e-commerce platforms, yet their usability evaluation often lacks standardization. Existing work on evaluating recommender systems, from toolkits to infrastructure, mainly assesses recommendation algorithms rather than user experience. This focus leads to a limited understanding of recommender systems’ effectiveness, as it overlooks the role of user interface design, especially carousel-based interfaces, in user experience. In response, this paper introduces a web-based infrastructure for the usability assessment of carousel-based interfaces. Our infrastructure is adaptable for various domains and setups, and its modular design allows for potential expansion.
