This paper provides an examination and categorization of Human Computer Interaction (HCI) requirements for the support of Electronic Business (eBusiness) and Electronic Commerce (eCommerce) in the context of intranets, extranets, and the Internet. The relationship of these HCI requirements to eBusiness is explored. Several methods are used to develop the requirements, including the application of grounded theory. The requirements uncovered are included in a framework to better enable the understanding of eBusiness requirements for the computer desktop.
