User test of the interaction designs

In summer we conducted two workshops with ten visually impaired and blind internet users to create a first draft of an interaction design for a browser-based privacy-enhancing tool, which allows blocking trackers.

The created interaction designs (in the form of as HTML prototypes) will be evaluated with ten user tests and compared to the existing tool Ghostery. Based on the evaluation results, we will revise the interaction-concepts and derive general design guidelines.
