1. A method comprising: outputting, by a computing device and for display, a graphical keyboard comprising a plurality of keys; receiving, by the computing device, an indication of current input detected at a presence-sensitive display operatively coupled to the computing device; determining, by the computing device, a distance between a first location on the presence-sensitive display at which a key of the graphical keyboard is output and a second location of the presence-sensitive display at which the current input was detected; determining, by the computing device, an elapsed time between a first time that a previous input was detected at the presence-sensitive display a second time that the current input was detected at the presence-sensitive display, the first time occurring before the second time; determining, by the computing device, based at least in part on the distance and the elapsed time, that an input posture type of the previous and current inputs is a single-finger input posture type or a bimodal input posture type; and selecting, by the computing device based at least in part on the input posture type, a spatial model that is used for determining a probability that at least one of the one or more of the plurality of keys has been selected.
