ABSTRACT
This chapter presents two case studies that show the development and application of the situated CE+ framework, respectively for naval ships and space stations. It reviews a model of cognitive task load (CTL) that could be used to harmonize the task demands to the human capacities via task allocation and design of cognitive support, for example, to prevent overload and cognitive lock-up during damage control on the naval ship. The chapter provides an overview of the cognitive ingredients of situated engineering for adaptive maritime aiding task environments (SEAMATE): the CTL model, the support concepts, and the adaptive functions. It also presents some cognitive ingredients of situated usability engineering for interactive task environments (SUITE): the hypermedia processing model and corresponding support functions. Although the SUITE and SEAMATE methods are "situated" and tailored to the space and, respectively, the naval domain, they are founded on research on task support in complex task environments in general.
