The role of interface design is to enable communication between people and the technical product such as a cellular phone, computer, or PDA. To use the product successfully, the interface design should be easy to use. The objective of this paper is to create a practical and user-friendly interface design for a wireless device to control home appliances. In order to control home appliances with a cellular phone, the author suggests a natural (intuitive) interface design that is friendly and attractive to users, based on their experience, and effectively uses graphic elements such as layout, icon, color, and text. As part of this natural (intuitive) interface design, the author suggests using a wheel key to control a cursor system for navigating a cellular phone screen. A usability test was conducted to determine problems people have while using the prototype. The results of the usability test indicated that the user interface was successful, and participants were satisfied with the prototype.
