This master thesis design and implement new software which can help children learn and practice "Wubi" Chinese typewriting. The purpose of designing this software is to effectively reduce the phenomenon in China known as "forget how to write while taking pen", so-called character amnesia. First we interviewed two experienced teachers and one class of pupils from an elementary school to collect data. Based on the data we collected, we built a set of prototypes by using PowerPoint on computer and evaluated it by three invited children who belonged to our target user group. After we modified our prototype, we implemented it on a computer using the Java programming language. When the process came to the evaluation part, we invited four students who had background knowledge on the field of HCI and its evaluation methods, to help us finish a cognitive walkthrough evaluation. Although some part of our software, such as certain interfaces and sequences, should be improved in the future work, the opinions of the evaluators were mostly positive.
