Abstract

A method of controlling a portable electronic device having a touch-sensitive display includes detecting a first touch on the touch-sensitive display, detecting a second touch on the touch-sensitive display while the first touch is maintained, selecting one of the first and second touches as a selected touch based on start or end times of the first and second touches, and determining which one of a plurality of features is associated with a location of the selected touch.

Claims (25)

1 . A method comprising:

detecting a first touch on a touch-sensitive display;

detecting a second touch on the touch-sensitive display while the first touch is maintained;

selecting one of the first and second touches as a selected touch based on start or end times of the first and second touches; and

determining which one of a plurality of features is associated with a location of the selected touch.

2 . The method according to claim 1 , wherein selecting comprises selecting based on a later start time of the selected touch.

3 . The method according to claim 1 , wherein determining occurs prior to detecting the second touch.

4 . The method according to claim 1 , comprising, when the first touch is the selected touch, disregarding the second touch, and when the second touch is the selected touch, disregarding the first touch.

5 . The method according to claim 4 , wherein disregarding comprises disregarding signals from the disregarded touch.

6 . The method according to claim 1 , wherein detecting a first touch comprises determining touch coordinates of the first touch and detecting a second touch comprises determining touch coordinates of the second touch.

7 . The method according to claim 1 , comprising rendering a keyboard on the touch-sensitive display prior to detecting the first touch and wherein the plurality of selectable features comprises at least one of alphanumeric and symbolic characters from a keyboard.

8 . The method according to claim 1 , wherein the one of the plurality of features is a character from a keyboard.

9 . The method according to claim 1 , comprising detecting an end of the first touch prior to selecting.

10 . The method according to claim 1 , wherein determining occurs prior to the end of the first touch.

11 . A portable electronic device comprising:

a touch-sensitive display; and

at least one processor operably connected to the touch-sensitive display, and configured to detect a first touch on the touch-sensitive display, detect a second touch on the touch-sensitive display while the first touch is maintained, select one of the first and second touches as a selected touch based on start or end times of the first and second touches, and determine which one of a plurality of features is associated with a location of the selected touch.

12 . A computer-readable medium having computer-readable code executable by at least one processor of an electronic device comprising a touch-sensitive display to detect a first touch on the touch-sensitive display, detect a second touch on the touch-sensitive display while the first touch is maintained, select one of the first and second touches as a selected touch based on start or end times of the first and second touches, and determine which one of a plurality of features is associated with a location of the selected touch.

13 . A method comprising:

detecting a first touch on a touch-sensitive display;

detecting a second touch on the touch-sensitive display while the first touch is maintained;

identifying one of the first and second touches to disregard based on start or end times of the first and second touches.

14 . The method according to claim 13 , wherein disregarding comprises disregarding based on a later start time of the disregarded touch.

15 . The method according to claim 13 , comprising, when the first touch is the disregarded touch, selecting the second touch, and when the second touch is the disregarded touch, selecting the first touch.

16 . The method according to claim 15 , comprising determining which one of a plurality of features is associated with a location of the selected touch.
