Abstract

Systems and methods that enable a client device to control scrolling of image data such as slices of MR or CT images using a scrolling gesture. The gesture may be received from a human interface device, and may be mouse moments, touchpad inputs, game controller movements, trackball movements or a movements on a touch-sensitive display. When a scrolling gesture is received at the client device, a velocity and distance of the swipe may be measured. Based on a relationship of gesture velocity to slice scroll velocity, both fine and course scrolling may be provided through the gesture. Control of document scrolling on the display of a client device is also provided.

Claims

1. A method of adaptive scrolling of images within a set of images, comprising:

defining a relationship of gesture velocity to an image scroll velocity;

displaying, in a display, an image from within the set of images;

receiving a user-initiated gesture;

determining a velocity of the user-initiated gesture; and

correlating the velocity of the user-initiated gesture to the image scroll velocity using the relationship to scroll the images on the display.

2. The method of claim 1, the display comprising a touch-sensitive display, the method further comprising:

determining that the gesture is a swipe on the touch-sensitive display; and

determining a swipe velocity to determine an image scroll velocity.

3. The method of claim 1, the display comprising a touch-sensitive display, the method further comprising:

determining that the gesture is a pan gesture on the touch-sensitive display; and

updating a pan gesture velocity and image scroll velocity over a duration of the pan gesture.

4. The method of claim 1, further comprising applying an adjustment to the relationship based on a size of the display.

5. The method of claim 4, wherein the adjustment is a multiplier.

6. The method of claim 1, wherein the image scroll velocity is relatively slower for slower gesture velocities and wherein the image scroll velocity is relatively faster for faster gesture velocities.

7. The method of claim 6, wherein a constant minimum scroll velocity is predetermined for a first range of the relatively slower gesture velocities and wherein a constant maximum swipe velocity is predetermined for a second range of the relatively faster gesture velocities.

8. The method of claim 7, wherein the scroll velocity is variable in accordance with gesture velocity between the first range and the second range.

9. The method of claim 1 wherein the gesture is received from a human interface device.

10. The method of claim 9, wherein the gesture is selected from the group consisting of mouse moments, touchpad inputs, game controller movements, and trackball movements.

11. A computing device for viewing a set of images on a display thereof, comprising:

a memory that stores one or more modules; and

a processor that executes the one or more modules to;

define a relationship of gesture velocity to an image scroll velocity;

display an image from within the set of images on the display;

receive a user-initiated scrolling gesture;

determine a velocity of the user-initiated gesture; and

correlate the velocity of the user-initiated gesture to the image scroll velocity using the relationship to scroll the images on the display.

12. The computing device of claim 11, wherein the processor further executes the one or more modules to:

determine that the image gesture is a swipe on a touch-sensitive display; and

determine a swipe velocity to determine an image scroll velocity.

13. The computing device of claim 11, wherein the processor further executes the one or more modules to:

determine that the image gesture is a pan gesture on a touch-sensitive display; and

update a pan gesture velocity and image scroll velocity over a duration of the pan gesture.

14. The computing device of claim 11, wherein the processor further executes the one or more modules to apply an adjustment to the relationship based on a size of the display.

15. The computing device of claim 11, wherein the image scroll velocity is relatively slower for slower image gesture velocities and wherein the image scroll velocity is relatively faster for faster image gesture velocities.

16. The computing device of claim 15, wherein a constant minimum scroll velocity is predetermined for a first range of the relatively slower image gesture velocities and wherein a constant maximum swipe velocity is predetermined for a second range of the relatively faster image gesture velocities.

17. The computing device of claim 16, wherein the image scroll velocity is variable in accordance with image gesture velocity between the first range and the second range.

18. The computing device of claim 11, wherein the gesture is received from a human interface device.

19. The computing device of claim 18, wherein the gesture is selected from the group consisting of mouse moments, touchpad inputs, game controller movements, and trackball movements.

20. A method of adaptive scrolling a document displayed on a display of a computing device, comprising:

defining a relationship of image gesture velocity to a document scroll velocity, the relationship being based on one of a screen size of the display and a document size;

displaying the document on the display;

receiving a user-initiated gesture from a human interface device of the computing device;

determining a velocity of the user-initiated gesture; and

correlating the velocity of the user-initiated gesture to the document scroll velocity using the relationship to scroll the images on the display.
