ABSTRACT:
The present invention can be used either as a joystick controller having three dimensions of control or as a three dimensional pressure sensor for signature verification or other purposes. The invention comprises a flexible web including a first deflection zone which extends between first and second spaced apart points on the web. A second deflection zone extends between third and fourth spaced apart points on the web. The first and second deflection zones intersect to divide each of the zones into first and second sections. A first fixed yoke includes first and second arms which are coupled to the first and second points on the web. A second floating yoke includes first and second arms which are coupled to the third and fourth points on the web. A web deflection device is coupled to the second yoke to transmit the mechanical input deflections to the web. Sensor means is coupled to the first and second deflection zones of the web for generating an electrical output signal representative of the mechanical input displacements.
