1 : A method comprising: outputting, by a computing device and for display at a presence-sensitive display, a graphical keyboard comprising a plurality of keys; receiving, by the computing device, an indication of a multi-touch gesture detected at the presence-sensitive display, the multi-touch gesture performed by a user having a first finger and a second finger, the multi-touch gesture comprising a first sub-gesture of the first finger that traverses a first group of keys of the plurality of keys and a second sub-gesture of the second finger that traverses a second group of keys of the plurality of keys, the first sub-gesture being disjoint from the second sub-gesture; determining, by the computing device and in response to receiving the indication of the first sub-gesture of the first finger and the second sub-gesture of the second finger, a candidate word based at least in part on the first and second groups of keys, wherein the determining comprises: determining, by the computing device and based at least in part on the first sub-gesture of the first finger, a first group of points on the presence-sensitive display traversed by the first sub-gesture; determining, by the computing device and based at least in part on the second sub-gesture of the second finger, a second group of points on the presence-sensitive display traversed by the second sub-gesture; determining, by the computing device and based at least in part on the first and second groups of points on the presence-sensitive display, at least one probability that at least one key included in at least one of the first and second groups of keys is associated with at least one of the first sub-gesture of the first finger and the second sub-gesture of the second finger; and determining, by the computing device, the candidate word based at least in part on the at least one probability that the at least one key is associated with at least one of the first sub-gesture of the first finger and the second sub-gesture of the second finger; and outputting, by the computing device and for display at the presence-sensitive display, the candidate word.
