Abstract

An action inferring facility for a multimodal interface called Edward is described. Based on the actions the user performs, Edward anticipates future actions and offers to perform them automatically. The system uses inductive inference to anticipate actions. It generalizes over arguments and results, and detects patterns on the basis of a small sequence of user actions, e.g. “copy a lisp file; change extension of original file into .org; put the copy in the backup folder”. Multimodality (particularly the combination of natural language and simulated pointing gestures) and the reuse of patterns are important new features. Some possibilities and problems of action inferring interfaces in general are addressed. Action inferring interfaces are particularly useful for professional users of general-purpose applications. Such users are unable to program repetitive patterns because either the applications do not provide the facilities or the users lack the capabilities.
