A hand-held joystick has spaced-apart groups of accelerometers and is free to move or rotate on multiple axes. Each group has, for example, three mutually perpendicular accelerometers, with each one producing an electrical signal responsive to linear acceleration along one axis. The signals are combined to derive a definition of acceleration of the joystick along the three mutually perpendicular linear axes and/or rotation about these axes. The combined signal is used by an electrical control system which provides input to a device being controlled. The signal to the device under control is responsive to the motion of the joystick.
A control device responsive to linear movement along three mutually perpendicular axes and to rotation about said three axes, comprising: a hand-held enclosure; wherein said enclosure is manually movable with respect to a movable vehicle; at least two spaced-apart sets of multiple, mutually-perpendi
A control device responsive to linear movement along three mutually perpendicular axes and to rotation about said three axes, comprising: a hand-held enclosure; wherein said enclosure is manually movable with respect to a movable vehicle; at least two spaced-apart sets of multiple, mutually-perpendicular accelerometers mounted in said enclosure, each one of said accelerometers generating an electrical signal representative of acceleration of the device along one of said axes; in combination with a second control device containing at least two sets of multiple accelerometers fixedly mounted in said movable vehicle, said accelerometers of said second control device in each set being mutually perpendicular and producing electrical signals responsive to acceleration of said vehicle, and means for combining the electrical signals from said control device and said second control device to produce an indication of acceleration of said hand-held housing with respect to said movable vehicle.
