Portable electronic device and method of controlling same
View Patent ↗A method includes displaying information on a touch-sensitive display of a portable electronic device, rendering a continuous scroll indicator in response to receipt of a continuous scroll input at the portable electronic device, detecting, on the touch-sensitive display, a touch associated with the continuous scroll indicator, and scrolling the information based on a direction of the change, when a change in touch location is determined.
1. A method comprising:
displaying information on a touch-sensitive display of a portable electronic device;
receiving a continuous scroll input to enter a continuous scroll mode, the continuous scroll input comprising a first touch on the touch-sensitive display;
rendering a continuous scroll indicator in response to receipt of the first touch at the portable electronic device;
when a second touch is detected, within a threshold period of time, on the continuous scroll indicator rendered in response to receipt of the first touch, and a change in touch location of the second touch is determined, scrolling the information based on a direction of the change; and
when a second touch is not detected within a threshold period of time, exiting the continuous scroll mode and discontinuing display of the continuous scroll indicator.
2. The method according to claim 1 , comprising determining a distance of the change, and wherein scrolling comprises scrolling at a rate based on the distance of change.
3. The method according to claim 1 , wherein the continuous scroll indicator comprises a scroll handle.
4. The method according to claim 3 , wherein detecting a second touch on the continuous scroll indicator comprises detecting a second touch on the scroll handle.
5. The method according to claim 4 , comprising changing a location of the scroll handle with the change in touch location of the second touch.
6. The method according to claim 5 , comprising determining a distance of change in location of the scroll handle, and wherein scrolling comprises scrolling at a rate based on the distance of change.
7. The method according to claim 4 , wherein detecting a second touch on the handle comprises detecting a second touch at a location that is within an area surrounding the handle.
8. The method according to claim 1 , comprising determining a component of the direction of change, and wherein scrolling comprises scrolling based on the direction of the component.
9. The method according to claim 8 , wherein determining a component comprises determining a vertical component relative to the orientation in which the information is rendered.
10. The method according to claim 1 , comprising determining one of an up direction and a down direction relative to the orientation in which the information is rendered.
11. The method according to claim 1 , comprising exiting the scroll mode when the second touch ends.
12. The method according to claim 1 , wherein the first touch comprises a double tap input detected on the touch-sensitive display.
13. The method according to claim 1 , comprising continuing scrolling until the second touch ends.
14. The method according to claim 1 , wherein detecting a second touch on the continuous scroll indicator comprises detecting a second touch at a location that is within an area surrounding the continuous scroll indicator.
15. A non-transitory computer-readable storage device having computer-readable code executable by at least one processor of the portable electronic device to perform the method of claim 1 .
16. A portable electronic device comprising:
a touch-sensitive display configured to display information; and
a processor connected to the touch-sensitive display to:
receive a continuous scroll input to enter a continuous scroll mode, the continuous scroll input comprising a first touch on the touch-sensitive display;
render a continuous scroll indicator in response to receipt of the first touch at the portable electronic device;
when a second touch is detected, within a threshold period of time, on the continuous scroll indicator rendered in response to receipt of the first touch, and a change in touch location of the second touch is determined, scroll the information based on a direction of the change; and
when a second touch is not detected within a threshold period of time, exit the continuous scroll mode and discontinue display of the continuous scroll indicator.
17. A method comprising:
displaying information on a touch-sensitive display of a portable electronic device;
receiving a continuous scroll input to enter a continuous scroll mode, the continuous scroll input comprising a first touch on the touch-sensitive display;
rendering a continuous scroll indicator having a scroll handle in response to receipt of the first touch at the portable electronic device;
when a second touch, is detected, within a threshold period of time, on the scroll handle of the continuous scroll indicator rendered in response to receipt of the first touch, and a change in touch location of the second touch is determined, scrolling the information in a direction based on a direction of the change and at a rate based on a distance of the change; and
when a second touch is not detected within a threshold period of time, exiting the continuous scroll mode and discontinuing display of the continuous scroll indicator.
