The Effects of Display-Control I/O, Compatibility, and Integrality on Dual-Task Performance and Subjective Workload,

Abstract

The utility of speech technology was evaluated in terms of three dual-task principles: resource competition between the time-shared tasks, stimulus-central processing-response compatibility, and task integrality. Empirical support for these principles was reviewed. Two studies investigating the interactive effects of the three principles were described. Objective performance and subjective workload ratings for both single-and dual-task measures. It was shown that all three principles played an important role in determining an optimal task configuration. This was reflected in both the performance measures and the subjective measures. Therefore, consideration of all three principles is required to insure proper use of speech technology in a complex environment.
