Foot operated navigation and interaction for virtual reality experiences

1. An apparatus for creating movement in a virtual reality for a user comprising:

a computer;

a virtual reality headset in communication with the computer that is worn on the head of the user so the user sees the virtual reality shown by the headset and produced by the computer in the headset; and

a foot controller in communication with the computer against which the user moves at least one of his feet to create control signals with the foot to cause movement in the virtual reality shown by the headset, the control signals from a time-varying pressure variation on the bottoms of the feet of the user are used by the computer to create a moving vehicle in virtual reality, the movement of the vehicle created by the computer in virtual reality is either a rolling, sliding, sailing, hovering or flying moving vehicle, the control signals provide controls that always maintain static balance for the user's body and are used together with visual feedback from visuals in the virtual reality created by the computer which convey a degree and direction of physical tilt and roll consistent with a reactive force to an illusory lateral movement that the user perceives as downward with respect to the user's body, the control signals are created with isometric gestures with each individual foot of the user, the control signals provide a total number of linearly separable dimensions of control that the user can impart to the pressure imagine surface is at least 12, six dimensions per foot, the control signals are created from auxiliary foot gestures of toe curl which provide for linearly separable dimensions of control for the user in the virtual reality created by the computer.

2. The apparatus of claim 1 wherein for each foot of the user, the six dimensions fall into two classes, with a first class having three kinematic dimensions: one kinematic dimension for forward or rearward position of the foot upon the foot controller, one kinematic direction for side to side position of the foot upon the foot controller, and one kinematic dimension of turning the foot inward or outward about a vertical axis of the users ankle, and a second class having three dynamic dimensions: one dynamic dimension for a total pressure of the foot upon the foot controller, one dynamic dimension for how weight of the foot is distributed back onto a heel versus forward onto a forefoot, and one dynamic dimension for how the weight of the foot is distributed onto the inner edge of the foot, otherwise called pronation, versus an outer edge of the foot, otherwise called supination.

3. The apparatus of claim 2 wherein the control signals are created using intermittent control gesture events by lifting 1 foot off of the foot controller and placing the foot back down onto the foot controller.

4. The apparatus of claim 3 wherein the foot controller is disposed only within the user's shoes or foot apparel.

5. The apparatus of claim 4 including a hand controller from which control signals are provided to the computer for the virtual reality.

6. A method for creating movement in a virtual reality for a user comprising the steps of:

the user seeing the virtual reality shown by a virtual headset and produced by a computer in the headset, the virtual reality headset in communication with the computer that is worn on the head of the user; and

the user moving at least one of his feet against a foot controller to create control signals with the foot to cause movement in the virtual reality by the computer, the foot controller in communication with the computer, including the step of using by the computer control signals from my time-varying pressure variation on the bottoms of the feet of the user to create a moving vehicle in virtual reality, including the step of the computer moving the vehicle created by the computer in virtual reality is either rolling, sliding, sailing, hovering or flying, including the step of the control signals providing controls that always maintain static balance for the user's body and are used together with visual feedback from visuals in the virtual reality created by the computer which convey a degree and direction of physical tilt and roll consistent with a reactive force to an illusory lateral movement that the user perceives as downward with respect to the user's body, including the step of creating the control signals with isometric gestures with each individual foot of the user, the control signals provide a total number of linearly separable dimensions of control that the user can impart to the pressure imaging surface is at least 12, six dimensions per foot, including the step of creating the control signals from auxiliary foot gestures of toe curl which provide for linearly separable dimensions of control for the user in the virtual reality created by the computer.

7. The method of claim 6 including the step of using a hand controller by the user to create control signals.
