Except for hardware design, the user interface of mobile devices creates the first impression for users. Such phenomenon occurs more frequently in cellular phones than other devices. They are also used to reveal users' characters and preferences. Sounds, fonts, colors, and background images are used to express users' personalities. The demand for means of expressing one's character via mobile devices has been raised by advanced display technology, higher resolution and more colors. Flash Lite of Adobe Systems, Inc. and uiOne of Qualcomm, Inc. reflect these requirements, and achieve good results. But Flash Lite and uiOne have weakness as other solutions do. Users cannot exceed the functionality that each user interface system provides. This paper introduces a new downloadable user interface overcoming the disadvantages. The downloadable user interface includes multiple UI engines, so it supports different types of user interface. The downloadable user interface has been deployed on the Linux smartphone.
