Mobile trackball “bitra” / Trackball mouse

To improve efficiency and productivity in PC work in diverse work environments and work styles, we have developed an unconventional palm-sized 5-button trackball suitable for mobile use while keeping the advantage of a trackball’s “space-saving and comfortable PC operability.” The five “quiet-click” buttons (left and right buttons, wheel button, and side buttons) allow you to use it in any place or at any time--such as public facilities, conference rooms, midnight and morning--without worrying about the sound of clicking.
