Modeling command selection for speech-based applications
Jinjuan Heidi Feng · 2003
Command selection is an important problem in human computer interaction. We are applying a decision-making approach to model the process by which users select commands when multiple alternatives exist. Our initial focus is on speech-based systems, but the underlying approach is applicable to a wide range of interaction styles. Two empirical studies that provide a foundation for this research are complete and an initial decision model is proposed which specifies the factors that influence the command selection decisions and the relationships between those factors. Empirical studies are planned to investigate users' perceptions of individual model components and to validate the complete model.
