A good Human-Computer Interaction interface is the key technology of embedded system design. Higher demands of the practicality, aesthetics and audio-visual entertainment of embedded terminal are needed, especially in embbeded system handheld device. Notepad and electronic photo album are becoming an integral part of embedded device for their pracicality and good viewing. It has some practical significance and value to develop a notepad and an album with beautiful interface, rich functions and good interaction based on embedded terminal. The aim of this paper is to design and implement a notepad and an album in the embeded terminal environment. This paper presented the advantage of Linux and the building of QT developing environment, focused on the programming mechanism of developing software with Qt. It analysed the needs of the design, designed the specific interface and overall structure of notepad and album in the embeded terminal environment according to features of embedded application.This project designed and implemented the relevant functions of norepad(such as new file,open file ,edit file and delete file) as well as the relevant functions of album(such as enlarge 、minify、 rotate and move the
