Abstract
Task Analyses serve multiple purposes in system design, yet even with the resource intensive nature of such processes, further insight is still needed for the design of multi-modal systems. A Sensory Task Analysis (STA) allows a very granular level task decomposition into sensory information and interaction capability requirements that allows the determination of how individuals in the domain gather information as well as act upon this information in the operational environment. To complete this, however, knowledge of both the domain task and human information processing theory is required. Herein is presented a sensory-perceptual task taxonomy, a task analysis tool that facilitates the decomposition of domain tasks into generalizable sensory perceptual and response task types that greatly facilitates this process. This paper discusses the development and components that make up this taxonomy and presents a proof of concept example of how it may be used in an operational military domain. A discussion of potential applications and how this taxonomy fits within a tool to define optimal system fidelity requirements is also presented.
