Abstract:

Human Computer Interaction (HCI) is the design and implementation of interactive computing systems that users can interact with. It includes desktop systems in different devices. Success of a technology simply results from the easiness with which the user can interact with it [2]. A simple and easy way to use a system doesn't mean that a simple technology is behind such a system. The most important concepts in HCI are functionality and usability. Usability is when a user utilizes the system's functions easily, properly and clearly. Functionality and usability may vary from one system to another
