Abstract:
A transducer apparatus operable on a supporting surface for converting the motion of an appendage of an operator into electrical signals interpretable by an electronic signal processing device, comprising:(a) a base member adapted for translational motion in all planar directions parallel to and relative to said supporting surface in response to translational motion of the appendage; (b) a translational sensing assembly capable of detecting said translational motion and producing electrical signals therefrom; (c) a member responsive to pitch motion from the appendage; (d) a pitch motion sensing assembly capable of detecting said pitch motion and producing electrical signals therefrom; (e) a member responsive to roll motion from the appendage; (f) a roll motion sensing assembly capable of detecting said roll motion and producing electrical signals therefrom; (g) a member responsive to yaw motion from the appendage; (h) a yaw motion sensing assembly capable of detecting said yaw motion and producing electrical signals therefrom; (i) a means for alternatively selecting electrical signals produced by the translational sensing assembly from electrical signals produced by the roll, pitch, and yaw sensing assemblies; and, (j) a top cover coupled to said base member, and free to move in pitch, roll, and yaw motion relative to said base member in response to the movements of said appendage.
