ABSTRACT
This chapter describes experiments and meta-analyses drawn from the tenets that predict easier workload and more intuitive processing of information. It explains theory-based support for multisensory displays, with special consideration of the growing interest in tactile information channels and the potential for enhanced intuitive displays for procedural tasks. The chapter discusses two theoretical frameworks, Multiple Resource Theory (MRT) and Prenav model, that generate predictions regarding how and when multisensory displays would be more effective. One approach that has reduced cognitive workload in high-workload situations, MRT, is based on advantages proposed to arise from multisensory display of information. While MRT is based on models of attentional resources in high workload situations, the Prenav model of sensory channel information more specifically includes the tactile modality and has a strong emphasis on performance that can be automated, such as steering, navigation, and control systems.
