A two axis joystick controller (14) produces at least one output signal in relation to pivotal displacement of a member (32) with respect to an intersection of the two axes. The member (32) is pivotally movable on a support (42) with respect to the two axes. The support (42) has a centrally disposed aperture (46). A light source (34) is mounted on the pivotally movable member (32) above the aperture (46) to direct light (47) through the aperture. A light sensor (48) is mounted below the aperture (46) in the support (42) at the intersection of the two axes to receive the light (47) from the light source (34) directed through the aperture (46). The light sensor (48) produces at least one output signal related to a location on the sensor (48) at which the light (47) from the light source strikes the sensor (48). The two axis controller (14) is small enough in size to be mounted on another, hand-operated X-Y controller (10) for thumb operation by a hand positioned to operate the other X-Y controller (10). Knob (18) has a saddle shaped top (20) dimensioned to receive the thumb.

A two-axis controller which produces at least an output signal in relation to pivotal displacement of a member with respect to an intersection of the two axes, which comprises a support and a member pivotally movable on a support with respect to the two axes, said support comprising a plate portion surrounding an elevated portion having a centrally disposed aperture and said member being in pivotal contact with said plate portion, a light source mounted on said pivotally movable member above the aperture to direct light through the aperture at the intersection of the two axes to receive light from said light source directed through the aperture, a light sensor producing at least one output signal related to a location on said sensor at which the light from said light source strikes the sensor.
