This thesis shows that the success of any user-interface development depends on three pillars guidelines documents and processes, users-interface software tools, and expert review and usability testing. In essence, it is about developing interactive products that are easy, effective, and enjoyable to use –from the users’ perspective. The aim of this thesis is to redress this concern by bringing usability into the design process. Typically, they have been engineered as systems to perform set functions. Many products that require users to interact with them to carry out their tasks have not necessarily been designed with the users in mind. These researchers deal with the physical, psychological and theoretical aspects of such interaction. As computer use became more widespread, the number of researchers specialized in studying the interaction between people and computers increased. The study of the strategies for Effective Human Computer Interaction (HCI) is a powerful primer on how - and why - some products satisfy customers while others only frustrate them.
