This device uses a controller similar to most other virtual gaming systems. As shown in the diagram there are sensors all around the joystick of the controller and attached to the joystick is a magnet. When the joystick is moved the sensors turn because the magnet gets moved closer to them. In reaction to that, the sensors send a signal through the controller and the controller sends signals to the dreamcast which interperates the electrical signals into movements on the screen. The visual memory unit was the Sega Dreamcast's memory card and it featured a monochromatic LCD screen. This was similar to the Gameboy controls. The memory card could play downloaded games from some other Dreamcast games. The VMU would connect to the back of the controller like a Nintendo 64 rumble pack would. There was also a microphone accesory that was a gray plastic, similar to the VMU accessory, it had a spherical green wind shroud. This showed clear signs of an advancing technology which could have led to the modern invention of the Xbox 360 headset that connects to the controller.
