The ultimate goal is to construe any arbitrary sequence of taps as a coherent message, grammatical and correctly spelled, and thus with no possible hint of error for the recipient. Ideally, it would also use information about the recipient, including relation, past interactions, interests, social network etc to construe a believable meaning.
