1. A text input method for an electronic apparatus with a touch sensitive display, wherein a virtual keyboard is displayed on said display so as to facilitate input of an intended character for a user by touching keys of said virtual keyboard with a pointer, wherein the method comprises:
- detecting a touch of a first key on the touch sensitive display at a first position;
defining a candidate area that has a configuration that is dependent upon a tap direction that extends between the first position and a second position, wherein the second position is a position of a previously detected touch of a second key of the touch sensitive display, and wherein said candidate area being relatively longer along a first axis and relatively shorter along a second axis, said first axis being parallel to said tap direction and said second axis being perpendicular to said first axis; and
determining said intended character by considering;
a plurality of candidate characters disposed at least partially within the candidate area, said plurality of candidate characters being determined with regard to a raw distance, said raw distance being a distance between said first position and a position corresponding to a character, andlinguistic probabilities of each character of said plurality of candidate characters being an intended character.

Abstract
It is presented a text input method for an electronic apparatus with a touch sensitive display, the apparatus comprising a user interface, wherein a virtual keyboard is displayed on the display so as to facilitate input of an intended character for a user by touching keys of the virtual keyboard with a pointer, wherein the intended character is determined by considering: a plurality of candidate characters, the plurality of candidate characters being determined with regard to a raw distance, the raw distance being a distance between a first position, the first position being a position of a detected touch of the pointer, and a position corresponding to a character, and linguistic probabilities of each character of the plurality of candidate characters being an intended character. A corresponding electronic apparatus and computer program product are also presented.

11. An electronic apparatus comprising a user interface with a touch sensitive display, and a controller coupled to said display, said user interface including a virtual keyboard which is presentable on said display so as to facilitate input of an intended character for a user by touching keys of said virtual keyboard with a pointer, each key being associated with a respective key area, said user interface including a character selection functionality for determining an intended character, said controller being configured to:
-
detect a touch on a first key of the touch sensitive display at a first position; define a candidate area that has a configuration that is dependent upon a tap direction that extends between the first position and a second position, wherein the second position is a position of a previously detected touch of a second key of the touch sensitive display and wherein said candidate area being relatively longer along a first axis and relatively shorter along a second axis, said first axis being parallel to said tap direction and said second axis being perpendicular to said first axis; and determine said intended character by considering; a plurality of candidate characters disposed at least partially within the candidate area, said plurality of candidate characters being determined with regard to a raw distance, said raw distance being a distance between said first position and a position corresponding to a character, and linguistic probabilities of each character of said plurality of candidate characters being an intended character. - View Dependent Claims (12, 13, 15)

16. An apparatus comprising a controller and a memory storing executable instructions that in response to execution by the controller cause the apparatus to at least perform the following:
-
detect a touch of a first key on a touch sensitive display at a first position; define a candidate area that has a configuration that is dependent upon a tap direction that extends between the first position and a second position, wherein the second position is a position of a previously detected touch of a second key of the touch sensitive display and wherein said candidate area being relatively longer along a first axis and relatively shorter along a second axis, said first axis being parallel to said tap direction and said second axis being perpendicular to said first axis; and determine said intended character by considering; a plurality of candidate characters disposed at least partially within the candidate area, said plurality of candidate characters being determined with regard to a raw distance, said raw distance being a distance between said first position and a position corresponding to a character, and linguistic probabilities of each character of said plurality of candidate characters being an intended character. - View Dependent Claims (17)
