Decision and stress: cognition and e-accessibility in the information workplace

This paper was based on a prestigious, IBM, invitation-only workshop in New York. New results of two major studies validated my extended cognitive user model, including all nine components. Uses include; evaluation of existing systems, user-requirements assessment, system development in combination with models of task, context of use and technology platform and through the concepts of cognitive augmentation / overload to identify future opportunities for new, accessible, cognitive solutions. Proof of concept of Simplex is demonstrated by the treatment of HCI accessibility problems older adults requirements, cognitive overload and as a generative theory for the development of new solutions.
