Abstract

A hand-activated controller including a base and a circuit board attached to the base is provided. The circuit board has an aperture extending therethrough, and first, second, third, and fourth switches disposed thereon proximate to the aperture. The controller further includes a shaft having a tubular portion and a plate portion. The plate portion is disposed proximate to the first, second, third and fourth switches. The controller further includes a ball-shaped member that is coupled to the tubular portion of the shaft, and a microprocessor. The microprocessor determines if the first, second, third and fourth switches transition from a first operational state to a second operational state indicating that the ball-shaped member and the shaft have been pushed downwardly toward the base, and to generate a first command signal in response thereto.

Claims

1. A hand-activated controller, comprising:

a base;

a circuit board attached to the base, the circuit board further having an aperture extending therethrough;

first, second, third, and fourth switches disposed on the circuit board and arranged around the periphery of the aperture;

a shaft having a first tubular portion, a second tubular portion and a plate portion secured to the shaft and located between the first tubular portion and the second tubular portion, the plate portion being located above the first, second, third and fourth switches;

a spring being disposed between the plate portion and the base, the spring extending through the aperture of the circuit board and being received by the second tubular portion;

a ball-shaped member being coupled to the first tubular portion of the shaft;

a microprocessor electrically coupled to the first, second, third and fourth switches;

the microprocessor configured to determine when the first, second, third and fourth switches transition from a first operational state to a second operational state indicating that the ball-shaped member and the shaft have been pushed downwardly toward the base, and to generate a first command signal in response thereto;

fifth and sixth switches disposed on the circuit board, the plate portion of the shaft having a ramp portion that contacts at least one of the fifth and sixth switches when the ball-shaped member and the shaft are rotated about a vertical axis extending through the shaft to transition at least one of the fifth and sixth switches from the first operational state to the second operational state; and

the microprocessor further configured to determine when at least one of the fifth and sixth switches transition from the first operational state to the second operational state indicating that the ball-shaped member and the shaft have been rotated, and to generate a second command signal in response thereto.

2. The hand-activated controller of claim 1, wherein the microprocessor is further configured to determine when only the first switch transitions from the first operational state to the second operational state, indicating the shaft is being tilted in a first direction;

and to generate another command signal in response thereto.

3. The hand-activated controller of claim 2, wherein the microprocessor is further configured to determine when only the second switch transitions from the first operational state to the second operational state, indicating the shaft is being tilted in a second direction;

and to generate a third command signal in response thereto.

4. The hand-activated controller of claim 3, wherein the microprocessor is further configured to determine when only the third switch transitions from the first operational state to the second operational state, indicating the shaft is being tilted in a third direction;

and to generate a fourth command signal in response thereto.

5. The hand-activated controller of claim 4, wherein the microprocessor is further configured to determine when only the fourth switch transitions from the first operational state to the second operational state, indicating the shaft is being tilted in a fourth direction;

and to generate a fifth command signal in response thereto.

6. The hand-activated controller of claim 1, further comprising:

a seventh switch disposed on the circuit board;

a lever pivotally coupled between an upper surface of the plate portion of the shaft and the seventh switch, such that when the shaft is moved upwardly, the lever contacts the seventh switch and transitions the seventh switch from the first operational state to the second operational state; and

the microprocessor further configured to determine when the seventh switch transitions from the first operational state to the second operational state indicating that the ball-shaped member and the shaft have moved upwardly relative to the circuit board, and to generate another command signal in response thereto.

7. The hand-activated controller of claim 6, wherein the base further comprises a tubular receiving portion that extends upward from the base.

8. The hand-activated controller of claim 7, wherein the tubular receiving portion extends through the aperture of the circuit board and the spring is received within the tubular receiving portion and the second tubular portion.

9. The hand-activated controller of claim 1, wherein the ball-shaped member includes a lower portion and an upper portion, the lower portion being coupled to the first tubular portion of the shaft, the upper portion having an interior surface defining a central interior space, the upper portion having a first electrical contact disposed proximate to the interior surface, the lower portion having a second electrical contact disposed in the central interior space proximate to the first electrical contact, such that when the upper portion is compressed the first and second electrical contacts are electrically coupled together;

and

the microprocessor further configured to determine when the first and second electrical contacts are electrically coupled together indicating the ball-shaped member has been compressed, and to generate another command signal in response thereto.

10. The hand-activated controller of claim 1, wherein the ball-shaped member includes a cap portion on a top surface of the ball-shaped member.

11. The hand-activated controller of claim 1, further comprising an upper housing portion coupled to the base, the upper housing portion having another aperture extending therethrough for receiving the shaft therethrough.

12. The hand-activated controller of claim 11, further comprising:

at least one function selection switch coupled to upper housing portion, the function selection switch being electrically coupled to the processor; and

the microprocessor configured to detect when the function selection switch transitions from the first operational state to the second operational state, to select at least one of;

an image morphing software function, an image warping software function, a clip art software function, an image cloning software function, and an image effects software function.

13. The hand-activated controller of claim 11, further comprising a pad that is shaped to receive a human palm thereon, the pad being coupled to the upper housing portion.

14. The hand-activated controller of claim 1, wherein the base further comprises a tubular receiving portion that extends upward from the base.

15. The hand-activated controller of claim 14, wherein the tubular receiving portion extends through the aperture of the circuit board and the spring is received within the tubular receiving portion and the second tubular portion.

16. The hand-activated controller of claim 15, wherein the ball-shaped member includes a lower portion and an upper portion, the lower portion being coupled to the first tubular portion of the shaft, the upper portion having an interior surface defining a central interior space, the upper portion having a first electrical contact disposed proximate to the interior surface, the lower portion having a second electrical contact disposed in the central interior space proximate to the first electrical contact, such that when the upper portion is compressed the first and second electrical contacts are electrically coupled together;
