Studies on information retrieval for children are not yet common. As young children possess a limited vocabulary and limited intellectual power, they may experience more difficulty in fulfilling their information need than adults. This paper presents an image retrieval user interface that is specifically designed for children. The interface uses relevance feedback and has been evaluated by letting children perform different search tasks. The tasks were performed using two interfaces; a more traditional interface – acting as a control interface – and the relevance feedback interface. One of the remarkable results of this study is that children did not favor relevance feedback controls over traditional navigational controls.
