Abstract

Keystrokes on a keyboard are predicted by constructing a model from a training corpus. The training corpus includes symbol sequences. The model predicts a set of symbols, where each symbol of the set continues a particular symbol sequence using variable-length subsequences of the particular symbol sequence. A particular length is chosen to maximize a probability that the predicting is correct. Keys on the keyboard are highlighted. The highlighted keys correspond to selected symbols in the set of symbols.
