Users’ overall feedback strongly varied according to their expertise and experience in using digital tools within their research practice. As for our main user group, i.e. researchers in the area of literature studies, the tests revealed that the dual nature of the dashboard view, where charts serve both for projection output and allow for selection input, was not considered as fully intuitive. Rather, it seemed that users would have preferred a more common input modality like plain text provided, e.g, by drop down lists or autocomplete text input. Users even tried to interact with the textual data in the table view. With OPAC search interfaces being one of the frequently used digital tools by the humanities researchers among our testers, users’ expectations appeared to adhere to a paradigm of textual query formulation and, potentially but not necessarily visual, query result presentation and refinement.
