Zusammenfassung:	The research presented advances a new, alternative approach to interface design based on a model of language acquisition through automatic adaptation. The model depends on a key observation about frequent user behavior: although individual users differ significantly in their preferred linguistic expression, each frequent user is quite consistent in her usage over time. This self-bounded aspect of user behavior is demonstrated empirically in an initial set of experiments using a simulated system and a later set of experiments using an implementation of the model. The regularity in each frequent user's linguistic behavior is exploited in the design of a general mechanism to learn idiosyncratic grammars. The mechanism explains perceived errors in the input utterance as deviations with respect to the system's current grammar The explanation is then transformed into new grammatical components that are capable of recognizing the general structure of the deviation in future interactions. Thus, in contrast to most existing interfaces, the adaptive interface is self-extending and allows the user to employ her own natural language for accomplishing tasks. The usefulness and robustness of adaptation is demonstrated by the implementation of the model in a working interface. The interface has been evaluated both on the data from the original simulations and in on-line interactions with real users. The results of the evaluation clearly show adaptation's effectiveness; the implementation was able to capture both the regularity and the idiosyncracy in the natural grammars of eight users.
