Abstract

Aspects of the systems and methods are described providing for modifying a presented interactive element or object, such as a cursor, based on user-input gestures, the presented environment of the cursor, or any combination thereof. The color, size, shape, transparency, and/or responsiveness of the cursor may change based on the gesture velocity, acceleration, or path. In one implementation, the cursor “stretches” to graphically indicate the velocity and/or acceleration of the gesture. The display properties of the cursor may also change if, for example, the area of the screen occupied by the cursor is dark, bright, textured, or is otherwise complicated. In another implementation, the cursor is drawn using sub-pixel smoothing to improve its visual quality.

Claims

1. A system for providing visual feedback in response to a gesture, the system comprising:

an image-capture device for obtaining digital images of a real-world object in 3D space;

a computer memory for storing a digital representation of a path of movement of the real-world object based on the captured images; and

a processor implementing;

changing a position of a presented interactive object in response to the movement of the real-world object; and

modifying a presentation property of the presented interactive object.

2. The system of claim 1, wherein modifying the presentation property of the presented interactive object is based on a property of the movement.

3. The system of claim 2, wherein the property of the movement comprises a velocity of the real-world object along the path or an acceleration of the real-world object along the path.

4. The system of claim 1, wherein modifying the presentation property of the presented interactive object is based on a current use mode of the interactive object.

5. The system of claim 1, further comprising a display for displaying the interactive object.

6. The system of claim 1, wherein the interactive object is a cursor.

7. The system of claim 1, wherein modifying the presentation property of the presented interactive comprises changing at least one of color, size, shape, and transparency.

8. The system of claim 1, wherein modifying the presentation property of the presented object comprises at least one of stretching the presented object based on its velocity or acceleration, changing a color of the presented object based on its velocity or acceleration, and changing a color of the object based on at least one of color, texture, and pattern of a screen area along the path.

9. The system of claim 1, wherein the processor further implements detecting that the path of movement does not correspond to a known gesture, and wherein modifying the presentation property of the presented interactive object comprises changing a color of the presented interactive object in response to detecting that the path of movement does not correspond to a known gesture.

10. The system of claim 1, wherein the real-world object is a hand of a user.

11. The system of claim 2, wherein the property of the movement comprises a latency between movement of the real-world object and movement of the presented interactive object, and wherein modifying the presentation property of the presented interactive object comprises stretching the presented object an amount related to the latency.

12. The system of claim 1, wherein the processor further implements detecting a presented element to which the presented interactive object is moving towards and changing a color of the presented interactive object to indicate interaction with the presented element.

13. A method for providing visual feedback in response to a gesture, the method comprising:

obtaining, using an image-capture device, digital images of a real-world object in 3D space;

storing, in a computer memory, a digital representation of a path of movement of the real-world object based on the captured images;

changing a position of a presented interactive object in response to the movement of the real-world object; and

modifying at least a presentation property of the presented interactive object.

14. The method of claim 13, wherein modifying the presentation property of the presented interactive object is based on a property of the movement.

15. The method of claim 14, wherein the property of the movement comprises a velocity of the real-world object along the path or an acceleration of the real-world object along the path.

16. The method of claim 13, wherein modifying the presentation property of the presented interactive object is based on a current use mode of the interactive object.

17. The method of claim 13, further comprising displaying, on a display, the interactive object.

18. The method of claim 13, wherein the interactive object is a cursor.

19. The method of claim 13, wherein modifying the presentation property of the presented interactive comprises changing at least one of color, size, shape, and transparency.

20. The method of claim 13, wherein modifying the presentation property of the presented object comprises at least one of stretching the presented object based on its velocity or acceleration, changing a color of the presented object based on its velocity or acceleration, and changing a color of the object based on at least one of a color, texture, and pattern of a screen area along the path.

21. The method of claim 13, further including detecting that the path of movement does not correspond to a known gesture, and wherein modifying the presentation property of the presented interactive object comprises changing a color of the presented interactive object in response to detecting that the path of movement does not correspond to a known gesture.

22. The method of claim 13, wherein the real-world object is a hand of a user.

23. The method of claim 14, wherein the property of the movement comprises a latency between movement of the real-world object and movement of the presented interactive object, and wherein modifying the presentation property of the presented interactive object comprises stretching the presented object an amount related to the latency.

24. The method of claim 13, further including detecting a presented element to which the presented interactive object is moving towards and changing a color of the presented interactive object to indicate interaction with the presented element.
