A passive-style buttonless mobile terminal

As a simple and intuitive interface, a new-style mobile terminal without a single operation button has been developed. The terminal contains an accelerometer and is operated by gestures, such as changing its inclination or by shaking it, instead of conventional button operation. The list of contents is presented on the terminal display as "bubbles flowing in water" instead of the conventional hierarchical structure. Using such gesture commands allows the user to easily browse contents such as text, video, still pictures, and music.
