  abstract = {When users search for information in domains they are not famil-
iar with, they usually struggle to formulate an adequate (textual)
query. Often users end up with repeating re-formulations and query
refinements without necessarily achieving their actual goals. In this
paper we propose a user interface that is capable to offer users flexi-
ble and ergonomic interaction elements to formulate even complex
queries in a simple and direct way. We call this principle
vague
query formulation by design
. By this formulation we like to point
out its design-driven origin. The proposed radial user interface sup-
ports phrasing and interactive visual refinement of vague queries to
search and explore large document sets. The main idea is to pro-
vide an integrated view of queries and related results, where both
queries and results can be interactively manipulated and influence
each other. Changes will be immediately visualized. The concept
was implemented on a tablet computer and the usability was step-
wise evaluated during a formative and a summative evaluation pro-
cess. The results reveal high usability ratings, even if the concept
was completely unknown to our test users.},
