Generally speaking, we could conveniently and directly operate ordinary user interface by hand controller. But along with the progressing techniques and increasing functions of communication equipment for family use, the operation and interaction styles between people and device have become more and more abundant. Most of the multimedia contents can be run and displayed on different kinds of platforms without possessing remote control ability originally. If people can just use some simple instruments, such as cellular phone or PDA, to remotely control the multimedia application module running on the PC or digital TV, then the control would become vivid and interesting. But there are various controlled instruments, display devices, and different kinds of methods. People who want to make a specified device to have remote control ability functions must write many complex procedures or programs into the device. Even in just adding or modifying a new function, people must also find the original source program and design function procedures repeatedly, which make developing application systems a cost burden, waste of time, and inefficient. In this paper, we will construct a remote control interface generator system, under which designer can easily transfer specified control object of Java application system running on PC, such as control buttons and labels, and generate remote control interface with objects into cellular phone automatically. This will simplify the development process of creating a control interface and make the control system development and modification more flexible and elastic. Through directly generated controlling objects and functions into the cellular phone by interface generator, we could directly and easily control the Java application system running on the PC without needing to write complex programs into the cellular phone.
