Abstract

A method of facilitating input at an electronic device includes detecting a first touch at a first touch location on a touch-sensitive device; the first touch being associated with a first character; detecting a second touch at a second touch location on the touch-sensitive surface, the second touch being associated with a second character; when movement of one of the first touch and the second touch is detected, determining a distance between the first touch location and the second touch location, the distance being associated with a number of characters of an object; identifying candidate objects in reference data that match the number of characters and include an initial character that matches the first character and a final character that matches the second character; and displaying at least one candidate object.

Claims

1. A method of facilitating input at an electronic device, the method comprising:

detecting a first touch at a first touch location on a touch-sensitive device to select a first character of a virtual keyboard;

detecting a second touch at a second touch location on the touch-sensitive device to select a second character of the virtual keyboard;

in response to movement of one of the first touch and the second touch being detected, determining a distance between the first touch location and the second touch location, the distance being associated with a number of characters of an object;

identifying candidate objects in reference data that match the number of characters and include an initial character that matches the first character and a final character that matches the second character; and

displaying at least one candidate object.

2. A method as claimed in claim 1, comprising ordering the candidate objects that match the number of characters and include an initial character that matches the first character and a final character that matches the second character based on a criterion and displaying a most probable candidate object.

3. A method as claimed in claim 1, wherein when movement of one of the first touch and the second touch is detected, determining an updated distance.

4. A method as claimed in claim 1, comprising displaying a list of ordered candidate objects, the list including a most probable candidate object and the ordered candidate objects being selectable from the list.

5. A method as claimed in claim 4, comprising receiving an input, the input corresponding to one of the candidate objects of the list of ordered candidate objects.

6. A method as claimed in claim 1, comprising displaying a most probable candidate object prior to movement of the first touch being detected, an initial character of the most probable candidate object matching the first character and a final character of the most probable candidate object matching the second character.

7. A method as claimed in claim 1, wherein the touch-sensitive device is a touch-sensitive display.

8. A method as claimed in claim 5, wherein the input is generated in response to both touches ending.

9. A method as claimed in claim 2, wherein the criterion is frequency of use.

10. A method as claimed in claim 1, wherein the distance is associated with a number of characters of an object by determining a ratio of the distance to a screen width.

11. A non-transitory computer-readable medium comprising instructions executable on a processor of an electronic device for implementing the method of claim 1.

12. An electronic device comprising:

a housing;

a display exposed by the housing; and

functional components in the housing comprising a memory and a processor operably connected to the display and configured to;

detect a first touch at a first touch location on a touch-sensitive surface;

the first touch selecting a first character of a virtual keyboard, detect a second touch at a second touch location on the touch-sensitive surface, the second touch selecting a second character of the virtual keyboard, determine a distance between the first touch location and the second touch location in response to movement of one of the first touch and the second touch being detected, the distance being associated with a number of characters of an object, identify candidate objects in reference data that match the number of characters, include an initial character that matches the first character and a final character that matches the second character, and display at least one candidate object.
