Abstract

A controller apparatus includes two or more balls having a size sufficient for a human to manipulate with a single foot. Three or more bearings support at least one of the balls from below and permit rotation with respect to at least two axes. One or more position encoders are disposed proximate a surface of each of the two or more balls. The encoders are configured to determine a rotational displacement of each of the two or more balls with respect to two or more axes.

First claim

What is claimed is:

1. A controller apparatus, comprising:
two or more balls having a size sufficient for a human to manipulate with a single foot;
a support apparatus configured to support at least one of the two or more balls from below and restrict translation of the ball and permit rotation of at least one of the two or more the balls about its center with respect to at least two axes;
one or more position encoders disposed proximate a surface of each of the two or more balls, wherein the one or more encoders are configured to determine a rotational displacement of each of the two or more balls with respect to two or more axes, wherein the measured rotational displacement of the two or more balls is an input to a computer application and a velocity difference in the measured rotational displacement of the two or more balls is applied as an input to the computer application.

2. The apparatus from claim 1 wherein the one or more position encoders include optoelectronic sensors proximate to the surface of each of the two or more balls wherein the optoelectronic sensors are each configured to receive light from each of the corresponding balls.

3. The apparatus from claim 2 further comprising one or more light sources configured to illuminate a portion of each of the balls and each of the optoelectronic sensors are configured to receive light reflected from a surface of each of the corresponding balls.

4. The apparatus from claim 2 wherein a surface of each of the two or more balls is configured to emit light.

5. The apparatus from claim 4 further comprising one or more light sources mounted internal to each of the balls and a light conductive material coupled to each of the one or more light sources and configured receive light from the one or more light sources and emit the light on the surface of the corresponding balls.

6. The apparatus from claim 2 wherein each of the balls includes a surface with a random or semi random color pattern or patterned texture.

7. The apparatus of claim 6 wherein each of the optoelectronic sensors are configured to detect changes in the intensity of light reflected from the surface of each of the corresponding balls.

8. The apparatus of claim 1 wherein at least one of the balls includes a colored pattern or a texture on the surface of the ball.

9. The apparatus of claim 1 wherein the one or more position encoders include one or more rotary encoders having a shaft or axel configured to transmit a rotation of at least one of the balls to the rotary encoder.

10. The apparatus of claim 1 wherein at least one of the balls weighs between 2 and 10 Kilograms.

11. The apparatus of claim 1 wherein a weight of at least one of the balls is adjustable.

12. The apparatus of claim 1 further comprising one or more braking elements configured to reduce a velocity of rotation of at least one of the balls.

13. The apparatus of claim 12 wherein braking elements includes one or more electric motors coupled to at least one of the balls.

14. The apparatus of claim 1 the support apparatus includes a bearing, wherein the bearing includes a braking element configured to reduce a velocity of rotation of the bearing.

15. A controller apparatus, comprising:
two or more balls having a size sufficient for a human to manipulate with a single foot;
a support apparatus configured to support at least one of the two or more balls from below and restrict translation of the ball and permit rotation of at least one of the two or more the balls about its center with respect to at least two axes,
wherein at least one of the balls includes an internal cavity configured to hold a granular material or a fluid for adjusting the weight of the ball;
one or more position encoders disposed proximate a surface of each of the two or more balls, wherein the one or more encoders are configured to determine a rotational displacement of each of the two or more balls with respect to two or more axes.

16. The apparatus of claim 15 wherein an interior surface of at least one of the balls includes one or more features configured to interact with the granular material or fluid and resist change in rotation of the ball.

17. A controller apparatus, comprising:
two or more balls having a size sufficient for a human to manipulate with a single foot;
a support apparatus configured to support at least one of the two or more balls from below and restrict translation of the ball and permit rotation of at least one of the two or more the balls about its center with respect to at least two axes,
wherein at least one of the balls includes a ferromagnetic material inside of the ball and an electromagnet outside of the ball wherein the combination of ferromagnetic material and electromagnet is configured to reduce a velocity of rotation of the ball when the electromagnet is energized;
one or more position encoders disposed proximate a surface of each of the two or more balls, wherein the one or more encoders are configured to determine a rotational displacement of each of the two or more balls with respect to two or more axes.

18. The apparatus of claim 17 wherein the one or more breaking elements includes a brake pad in proximity to at least one of the balls and wherein the one or more breaking elements are coupled to an actuator configured to press the brake pad onto the corresponding ball.

19. A controller apparatus, comprising:
two or more balls having a size sufficient for a human to manipulate with a single foot;
a support apparatus configured to support at least one of the two or more balls from below and restrict translation of the ball and permit rotation of at least one of the two or more the balls about its center with respect to at least two axes;
one or more position encoders disposed proximate a surface of each of the two or more balls, wherein the one or more encoders are configured to determine a rotational displacement of each of the two or more balls with respect to two or more axes; and
an inertial measurement unit (IMU) coupled to at least one of the balls.
