Abstract

A rotation control interface is disclosed. A two-dimensional graphical user interface having a first control portion associated with rotation about a first axis and a second control portion associated with rotation about a second axis is displayed. An indication that at least one of the first control portion and the second control portion has been engaged is received. A controlled object associated with the graphical user interface is rotated about the axis or respective axes with which the engaged control portion or portions of the graphical user interface are associated.

Claims

1. A method of controlling rotation, comprising:

displaying a two-dimensional graphical user interface having a first control portion associated with rotation about a first axis and a second control portion associated with rotation about a second axis;

receiving an indication that at least one of the first control portion and the second control portion has been engaged; and

rotating a controlled object associated with the graphical user interface about the axis or respective axes with which the engaged control portion or portions of the graphical user interface are associated.

2. A method as recited in claim 1, wherein one or both of a rate and a direction of rotation is determined at least in part by the indication.

3. A method as recited in claim 1, wherein one or both of a rate and a direction of rotation is determined at least in part by a user input comprising or in addition to the is indication.

4. A method as recited in claim 1, wherein one or both of a rate and a direction of rotation is determined at least in part by a drag vector determined at least in part by comparing a first cursor position at which a cursor was located when the control was first engaged and a current cursor position.

5. A method as recited in claim 4, wherein the first cursor position corresponds to a first point at which a mouse button is clicked and the current cursor position corresponds to a second point to which the mouse is dragged, if at all.

6. A method as recited in claim 1, further comprising:

receiving an indication that the at least one of the first control portion and the second control portion has been pre-selected but not yet engaged; and

changing the appearance of the at least one of the first control portion and the second control portion from an initial unselected appearance state to a pre-selected appearance state.

7. A method as recited in claim 1, further comprising changing the appearance of the at least one of the first control portion and the second control portion to an engaged appearance state in response to receiving the indication.

8. A method as recited in claim 1, wherein the indication comprises a mouse click input received at a time when an associated cursor was positioned on the at least one of the first control portion and the second control portion.

9. A method as recited in claim 1, wherein the first control portion and the second control portion overlap in an overlap area.

10. A method as recited in claim 1, wherein the first control portion and the second control portion overlap in an overlap area and an engagement indication associated with the overlap area results in simultaneous control of rotation about the first and second axes being engaged and provided.

11. A method as recited in claim 1, wherein the user interface includes a third control portion associated with rotation about a first axis.

12. A method as recited in claim 1, wherein the first control portion comprises a double-headed arrow oriented perpendicular to the first axis of rotation.

13. A method as recited in claim 1, wherein the first control portion comprises a first double-headed arrow oriented perpendicular to the first axis of rotation and the second control portion comprises a second double-headed arrow oriented perpendicular to the first double-headed arrow, perpendicular to the second axis of rotation, and parallel to the first axis of rotation.

14. A method as recited in claim 13, wherein the graphical user interface further comprises a circular graphic on which first and second double-headed arrows are located.

15. A method as recited in claim 14, wherein the circular graphic comprises a two-dimensional graphic having style attributes that give it the appearance of a stylized sphere.

16. A method as recited in claim 1, further comprising receiving a reset function pre-select input and changing the graphical user interface to a reset pre-select display state in response to the reset function pre-select input.

17. A method as recited in claim 16, further comprising receiving a select input at a time when the graphical user interface is in the reset pre-select display state and resetting the controlled object to a three-dimensional orientation associated with a reset state.

18. A method as recited in claim 1, wherein the controlled object comprises a physical object.

19. A method as recited in claim 1, wherein the controlled object comprises a three-dimensional graphic.

20. A method as recited in claim 1, wherein the controlled object comprises a three-dimensional graphic associated with one or more of the following software applications:

word processing, presentation, desktop publishing, landscaping and architectural design, web authoring, computer aided design, and animation.

21. A method as recited in claim 1, wherein rotating a controlled object associated with the graphical user interface about the axis or respective axes with which the engaged control portion or portions of the graphical user interface are associated comprises causing a computer graphic rendering application or process to rotate the controlled object.

22. A user interface for controlling rotation, comprising:

a two-dimensional graphical user interface comprising;

a first control portion associated with rotation about a first axis; and

a second control portion associated with rotation about a second axis;

wherein engagement of at least one of the first control portion and the second control portion causes a controlled object associated with the graphical user interface to be rotated about the axis or respective axes with which the engaged control portion or portions of the graphical user interface are associated.

23. A system for controlling rotation, comprising:

a display device; and

a processor configured to;

display via the display device a two-dimensional graphical user interface having a first control portion associated with rotation about a first axis and a second control portion associated with rotation about a second axis;

receive an indication that at least one of the first control portion and the second control portion has been engaged; and

rotate a controlled object associated with the graphical user interface about the axis or respective axes with which the engaged control portion or portions of the graphical user interface are associated.

24. A computer program product for controlling rotation, the computer program product being embodied in a computer readable medium and comprising computer instructions for:

displaying a two-dimensional graphical user interface having a first control portion associated with rotation about a first axis and a second control portion associated with rotation about a second axis;

receiving an indication that at least one of the first control portion and the second control portion has been engaged; and

rotating a controlled object associated with the graphical user interface about the axis or respective axes with which the engaged control portion or portions of the graphical user interface are associated.
