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
