17. A computing device comprising: a display device; one or more processors; a user interface module operable by the one or more processors and configured to output, for display at the display device, a graphical keyboard comprising a plurality of character keys; and a gesture module operable by the one or more processors and configured to: receive an indication of a first input gesture, a first portion of the first input gesture indicating a first character key of the plurality of character keys and a second portion of the first input gesture indicating a second character key of the plurality of character keys, determine, based at least in part on the first character key and the second character key, a candidate word; output, for display by the user interface module at a region of the display device at which the graphical keyboard is displayed, a gesture completion path extending from the second character key, the second character key being the most recently indicated character key, and the gesture completion path being associated with the candidate word, output, for display by the user interface module at the region of the display device at which the graphical keyboard is displayed and adjacent to the gesture completion path, the candidate word, and select, in response to receiving an indication of a second input gesture substantially traversing the gesture completion path, the candidate word associated with the gesture completion path.
