ABSTRACT:
A multi-positional, multi-level user interface system including a keyboard hinged over a base surface for a pointing device such as a mouse. The keyboard and base rotate relative to each other about a hinge axis to reveal the surface, providing a portable keyboard and pointing surface. A kickstand can support the keyboard above the base while in an open position. The keyboard and pointing device can be used with two hands with the system resting in a user's lap. The keyboard can also swivel about an axis other than the hinge axis. The keyboard can swivel 180 degrees for left-handed use, and can be positioned at other detent angles. A mouse can also be stowed on the base with a magnetic, friction, or other coupling. The interface system can further act as a communication hub for other peripheral devices, such as a joystick, to communicate with a computing device.
