A Study Of Human-Computer Interaction Technology Application In Educational Software For Kids-Design And Implementation Of A Musical Educational System

Nowadays the importance of early education for kids is absorbing more attention from educational specialist and young children's parents. Musical education has been playing an important part in the early education of kids. It's known for being especially powerful in enhancing the development of kids' intelligence as well as healthy personality. Educational software has many advantages in kids' education. With the power of the computers we can make education more lively and interesting.How ever, at present, we can not say that computers and human can interact with each other in great harmony. People often find computers hard to understand and use. They often spend a lot of time learning how to use it, and that takes great effort. Even though, people still fail to understand the way computers work sometimes, that can make the user very frustrated.Children's intelligence is still in development, they can not afford learning dully to use computers for long time. That can be harmful to them. For this reason, educational software has to be easy to understand and use.The main goal of Human - Computer Interaction is to make software easier to use and understand, to make human and computer interact in harmony. Our goal is to find how to take the advantage of Human-Computer Interaction technology to reduce the recognition burden, and help kids to understand the software easily and quickly.To reach the goal, we have made a research on a lot of existing educational software, both commercial and experimental, studied how they interact with children. We have designed and implemented a musical educational system, in which we have made use of the result of our study.In this paper, we will summarize the HCI technologies that we found most powerful during our study on the existing educational software, and introduce how these technologies are applied in our system. We will give the details about the design and implementation of our system. Then, introduce some important algorithm in the implication. Finally we will draw some conclusion and give some plans about further work.
