1. A control device for inputting information to a computer comprising:

  • a movable housing including an enclosure containing a fluid;

    heating means for heating the fluid in the enclosure;

    two first temperature sensing elements positioned within the enclosure such that the fluid moves across the two first temperature sensing elements in free convection during acceleration or inclination of the enclosure, the first temperature sensing elements providing first output signals which are representative of the respective temperatures of the two first temperature sensing elements;

    processing means for receiving the first output signals and providing an accelerometer signal representative of the acceleration or inclination of the enclosure; and

    transmission means for transmitting the accelerometer signal from the movable housing to a computer.
