Using the Internet, in particular search engines, children search for information for school, for their individual interests or simply for entertainment. Unfortunately, research shows that children face many difficulties when searching and browsing for information, even though there are(More)
We present first results of a logfile analysis on web search engines for children. The aim of this research is to analyse fundamental facts about how children's web search behaviour differs from that of adults. We show differences to previous results, which are often based on small lab experiments. Our large-scale analysis suggests that children search(More)
This paper describes a new user interface for a web search engine whose main target group are young users. We explain the main challenges for this user interface and discuss design decisions we made. Our interface is audio supported, contains possibilities for both searching through text input and navigating using menu categories, has a guidance figure for(More)
In this paper, we present the state of the art in the field of information retrieval that is relevant for understanding how to design information retrieval systems for children. We describe basic theories of human development to explain the specifics of young users, i.e., their cognitive skills, fine motor skills, knowledge, memory and emotional states in(More)
Search user interfaces (SUIs) are usually designed and optimized for generic users or for a certain user group. Users within the group are similar, e.g. concerning their information need, search goals or cognitive skills. These properties influence decisions made in the user interface (UI) design process. However, especially for young and elderly users,(More)
In this paper we describe the main challenges in designing search user interfaces for children. Young users require emotional support , language support, memory and cognitive support, interaction support and support to judge document relevance. We discuss possible solutions for each challenge. We also present a working prototype of a web search interface(More)
