Command management system for next-generation user input

Next generation user input and sensor technologies (such as speech, handwriting, vision, and physical location) present new possibilities for adaptable easy-to-use commands. These input modalities also present problems of noise and ambiguity, for which current “ad hoc” command processing services (e.g., undo) are often inconsistent and insufficient. Applications should work with sensor processors to interpret context-sensitive commands and to prevent irreversible errors. Moreover, sensor processor performance can increase with preknowledge about expected commands, from application designers or from real time analysis of user behavior. These observations suggest that operating system services for analyzing and refining user commands may be important for enabling robust, versatile human computer dialogue systems. We propose a context-sensitive command management system as a cornerstone for next-generation user input services
