1. A method, performed using one or more processors and a memory, for data input, the method comprising:
- receiving, through an input device and using the one or more processors, a first user input as part of a gesture,wherein the gesture comprises at least a first input selection that represents less than an entire word and a second input selection; and
wherein the gesture is a continuous stroke across a virtual keyboard from a first simulated key across one or more other simulated keys;
identifying, in the first user input, a bend from the first input selection to a current input location along the gesture;
determining that the bend indicates a third input selection that represents a portion of the word between the first input selection and the second input selection;
assigning to the bend a directional classification from a discrete set of directional classifications;
determining one or more candidates for the third input selection based on the candidates for the third input selection being in a direction, relative to the first input selection, corresponding to the assigned directional classification;
determining, using the one or more processors, one or more possible word suggestions based upon the first input selection and the one or more candidates for the third input selection,wherein the one or more possible word suggestions are determined prior to receiving the second input selection; and
providing, using a display, the possible word suggestions to the user.

Abstract
A system and method for entering text from a user includes a programmed processor that receives inputs from the user and disambiguates the inputs to present word choices corresponding to the text. In one embodiment, inputs are received in two or more modalities and are analyzed to present the word choices. In another embodiment, a keyboard is divided into zones each of which represents two more input characters. A sequence of zones selected by the user is analyzed to present word choices corresponding to the zone selected.

8. A non-transitory computer readable medium, storing instructions that, when executed by a computing system, cause the computing system to perform operations for data input, the operations comprising:
-
receiving a first user input as part of a gesture, wherein the gesture comprises at least a first input selection that represents less than an entire word and a second input selection; and wherein the gesture is a continuous stroke across a virtual keyboard from a first simulated key across one or more other simulated keys; identifying, in the first user input, a bend from the first input selection to a current input location along the gesture; determining that the bend indicates a third input selection that represents a portion of the word between the first input selection and the second input selection; assigning to the bend a directional classification from a discrete set of directional classifications; determining one or more candidates for the third input selection based on the candidates for the third input selection being in a direction, relative to the first input selection, corresponding to the assigned directional classification; determining one or more possible word suggestions based upon the first input selection and the one or more candidates for the third input selection, wherein the one or more possible word suggestions are determined prior to receiving the second input selection; and providing, using a display, the possible word suggestions to the user. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A computing system configured to perform data input, the system comprising:
-
one or more processors; a memory; a touch sensitive input configured to; receive, using the one or more processors, a first user input as part of a gesture, wherein the gesture comprises at least a first input selection that represents less than an entire word and a second input selection; and wherein the gesture is a continuous stroke across a virtual keyboard from a first simulated key across one or more other simulated keys; an input recognition module configured to; identify, in the first user input, a bend from the first input selection to a current input location along the gesture; determine that the bend indicates a third input selection that represents a portion of the word between the first input selection and the second input selection; assign to the bend a directional classification from a discrete set of directional classifications; determine one or more candidates for the third input selection based on the candidates for the third input selection being in a direction, relative to the first input selection, corresponding to the assigned directional classification; and determine, using the one or more processors, one or more possible word suggestions based upon the first input selection and the one or more candidates for the third input selection, wherein the one or more possible word suggestions are determined prior to receiving the second input selection; and a display configured to provide the possible word suggestions to the user. - View Dependent Claims (16, 17, 18, 19, 20)
