Information Retrieval for Young Users -- Usability of Existing Search Engines for Young Users -- Large-Scale Analysis of Children’s Queries and Search Interactions -- Differences in Usability and Perception of Targeted Web Search Engines between Children and Adults -- Search User Interface Design for Children -- Supporting Visual Searchers in Processing Search Results Target Groups.

The doctoral thesis of Tatiana Gossen formulates criteria and guidelines on how to design the user interfaces of search engines for children. In her work, the author identifies the conceptual challenges based on own and previous user studies and addresses the changing characteristics of the users by providing a means of adaptation. Additionally, a novel type of search result visualisation for children with cartoon style characters is developed taking children’s preference for visual information into account.
