ABSTRACT:
A device for connecting fitness equipment such as an exercise bicycle to a computer equipped with a game control device including a continuously variable resistance (e.g. industry standard architecture computers such as IBM PC/AT and compatibles equipped with a joystick adapter). The two states of the exercise bicycle (pedaling or not pedaling) are converted to the three states required by racing simulations (braking, coasting, accelerating) by means of a non-linear element in such a way that pedaling at speeds lower than a certain cross-over value is converted to various degrees of braking while pedaling at speeds higher than this value is converted to various degrees of acceleration. The cross-over pedaling speed which is converted to a resistance equal to that of a joystick in its middle position is lower than half the maximum speed. Within the range of possible pedaling speeds of the exercise bicycle, a smaller portion is used for braking and a greater portion is used for accelerating.
