36. An arrangement as defined in claim 27 wherein said transducer means to resolve said motion into components consists essentially of: a movable first surface; a conductive coating on the bottom side of said movable first surface with electrical connection thereto; a movable second surface; a resistive coating of between 100 and 100,000 ohms per square on the top side of said movable second surface, including spaced parallel conductors along two edges of said resistive coating with provision to apply a fixed potential to said conductors causing a voltage gradient in a first coordinate direction; a conductive coating on the bottom side of said movable second surface with electrical connection thereto; a fixed third surface; a resistive coating of between 100 and 100,000 ohms per square on the top side of said third surface, including spaced parallel conductors along two edges of said resistive coating oriented substantially perpendicular to said spaced parallel conductors of said second surface with provision to apply a fixed potential to said conductors causing a voltage gradient in a second coordinate direction; a plurality of insulated spacers located between said first and second surfaces, and between said second and third surfaces, to cause said first and second surfaces and said second and third surfaces to be noncontacting in the absence of external force on said first surface, such that pressure applied to a point on said first movable surface of such magnitude as to cause deflections around said insulated spacers will cause contact between said conductive coating on said first movable surface and said resistive coating on said second movable surface, with a voltage delivered to said electrical connection of said first surface proportional to the component of motion in said first coordinate direction; and contact between said conductive coating on said second movable surface and resistive coating on said third fixed surface will result in voltage delivered to said electrical connection of said second surface proportional to the component of motion in said second coordinate direction.
27. The arrangement as defined in claim 25 said means continuously responsive to operator input measures motion into substantially perpendicular directions; and further including transducer means to resolve said motion into components in the two substantially perpendicular directions; said system further including frequency tuning means; whereby one of each of said components of motion affects the frequency location of one of each of said resonant peaks or formants.
