I have received some positive feedback from engineers and pilots. One patent pending for it. Bell Helicopters is taking a look at it, but no promises. DARPA took a look as well as a few others.
Human Interface Rotor System helicopter (HIR) US Patent # 8226026
http://www.envisionrotorsystems.blogspot.com
The HIR airframe uses "human interface" in conjunction with an offset axis gimbal joint to "morph" the airframe thereby tilting the rotor disc for directional control. This slightly "flexes" the center of gravity. Charles Seibel was first to design a helicopter with human interface control. The GEN H4 uses a gimbal, yet it is a fixed pitch coaxial design. The HIR system does not have any linear shift in weight / CG.
The Human Interface Rotor System is only a motion and balance physical-interface system in its current configuration. The weight of the pilot is in balance with the rest of the upper airframe aft and distributed between the two airframes. The goal is to combine haptic and physical interface with a computer system that assists with pilot control. The HIR rotor system can then become a platform with an intelligent control system. Our Japanese counter parts are already working with HMI and HAM, but I have not seen it applied to rotorcraft as of yet. I have a few other things not related to rotorcraft that I'm working on....a chasis for an electric car, etc. I enjoy very much looking over what all of you are working on. Best regards to you all.

Sorry it's been a while. Had electrical issues,I hope that I've got most of it straight. 2nd test flight this week-end. Attached vid clip is just a power down.

Third CG hang test last week end for the mock up......waiting on parts for the carbon fiber airframe..............back to the filed for a week. No time.

Aluminum airframe mock up prior to going back to the gimbal. Shown here is a spherical bearing in place of the gimbal.
