Search User Interface Design for Children

Based on the user studies previously conducted by other researchers (Section 3.1), theories of human development (Section 2.2), and the findings from our user studies (Part II), in this chapter we derive conceptual challenges when designing web SUIs for children.We also discuss the possible solutions for these challenges and demonstrate some of them in a novel user interface called Knowledge Journey (Section 7.2). The evaluation of the Knowledge Journey interface is described in Section 7.3. We also conduct a user study in order to investigate the potential of voice controlled interactions. The results are presented in Section 7.4.
