Abstract

Embodiments of the present invention allow a user to input text on electronic devices with touch-sensitive surfaces without physical or virtual keyboards. In operation, a user may touch a certain position on a border of the touch-sensitive surface. A position corresponding to the detected touch is determined from among a plurality of predefined positions distributed along the border. In response, a character associated with the determined position is determined and input into the device.

Claims

enabling the user to configure a function represented by the determined third position, wherein the function enables modification of the four candidate alphanumeric characters represented by the first position corresponding to the detected first touch.

5. The method of claim 4, further comprising:

responsive to the third touch, displaying, by one or more computer processors, a prompt for a set of swipe gestures, wherein each swipe gesture of the set of swipe gestures is used to select a respective alphanumeric character of the plurality of candidate alphanumeric characters.

6. An electronic watch comprising:

a touch-sensitive surface representing a watch face; and

at least one processing unit configured to;

detect a first touch performed by a user on the touch-sensitive surface;

display a graphical representation of a border of the touch-sensitive surface;

display one or more indications of twelve predefined positions, wherein the twelve predefined positions are distributed along a circular border of the touch-sensitive surface at approximately 30 degree intervals;

determine a position corresponding to the detected first touch from among the twelve predefined positions;

determine that the position corresponding to the detected first touch represents four candidate alphanumeric characters, and in response, linearly display the four candidate alphanumeric characters, wherein no other predefined position represents the four candidate alphanumeric characters;

detect a swipe gesture on the touch-sensitive surface after the first touch;

select an alphanumeric character from the four candidate alphanumeric characters based on a direction of the detected swipe gesture, wherein the direction of the swipe gesture in relation to the position of the first touch is independent of a direction of the selected alphanumeric character in relation to the position of the first touch;

input the selected alphanumeric character into the electronic watch;

detect a second touch performed by the user on the touch-sensitive surface of the electronic watch;

determine a second position corresponding to the detected second touch from among the twelve predefined positions;

determine that the second position corresponding to the detected second touch represents at least eighteen candidate punctuation characters, wherein;

no other predefined position represents the at least eighteen candidate punctuation characters, and

the at least eighteen candidate punctuation characters represented by the second position corresponding to the detected second touch includes a first set of nine candidate punctuation characters and a second set of nine candidate punctuation characters;

display the first set of nine candidate punctuation characters in a first grid including three rows and three columns responsive to a first gesture detected on the touch-sensitive surface after the second touch; and

display the second set of nine candidate punctuation characters in a second grid including three rows and three columns responsive to a second gesture detected on the touch-sensitive surface after the second touch, wherein the second gesture is different from the first gesture.

7. The electronic device of claim 6, wherein the at least one processing unit is further configured to:
