The purpose of this study is to develop a user interface design method based on Human Design Technology (HDT). HDT has useful procedure to develop product design, however doesn't have clear procedure in case of user interface. So, we propose a method that is based on HDT to develop the user interface. This method has three steps to design the user interface. These steps are as follows. (1) description of interface specifications, (2) visualization of interface sequence and hierarchy of user tasks, and (3) prototyping of the user interface. A home security system's controller which was redesigned by the method was evaluated for verifying the effectiveness of this method. The improved user interface design was compared with the current controller by usability evaluation. The results of evaluation show this method is also useful and effective to develop the user interface.
