Development of a taxonomy of representational affordances for electronic health record system.

The application of Gibson's concept of affordances in Human-Computer Interaction (HCI) has lead to user interface improvements in many fields, like planning and visual environment. Design of user interface (representation) is very important to the functionality and usability of Electronic Health Record (EHR) System. Our project applied Gibson's theory of affordance and theory of distributed representations to develop a taxonomy of representational affordances for Electronic Health Record (EHR). Future work includes development of user-centered design and evaluation framework based on the representational affordances for Electronic Health Record System.
