The Cedar Operator Workload Assessment Tool (OWAT) is a flexible, highly extensible product with applications across a range of domains which have human factor-related considerations. Cedar OWAT is based on NASA’s MATB-II desktop application which is widely used in human factors and operator workload research.
Cedar is a task platform for the tablet designed to evaluate operator performance and workload. It was originally developed as an implementation of the NASA developed MATB-II for the tablet form factor with in-depth analysis of the relevant published knowledge-base informing the design. Cedar is both an accurate implementation of the workload assessment capabilities of the original software and a uniquely useful tool in its own right.
Flight test pedigree with limitless applications
Cedar OWAT can be used across a range of domains in support of human factors studies, and whilst the product was originally developed for the flight test community, the applications are limitless.
Designed from the ground up for the tablet
Cedar OWAT is based on NASA’s MATB-II desktop application. The principal design goal was to adapt MATB-II for the tablet platform, providing a solution that can be deployed to support human factors studies in non-office environments.
Flexible configuration
Configuration files for Cedar OWAT can be written in the modern, easy to read and compose JSON format. Cedar OWAT is compatible with the NASA MATB-II XML configuration format making it possible to use the same configuration files for both NASA MATB-II and Cedar OWAT.
Highly extensible
Task components for Cedar OWAT are adapted from NASA MATB-II existing components including Communications, Systems Monitoring and Resource Management tasks. Additional tasks can be developed to cater for specific needs.
