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, replacing conventional button operation. The list of contents is presented as "bubbles flowing in the water" instead of the conventional hierarchical structure. Using such gesture commands allows the user to enjoyably browse contents such as text, video, still pictures, and music.
