This search aims to explore the issues in developing the User Interface in mobile devices applications which is known as Human-Computer Interaction (HCI). The challenges that face the designers in developing the mobile UI are how to create usable and efficient UI and what are the guidelines or principles they should take into account to make interactive and interaction design. In addition, the software and hardware limitations they are encountered with, and also how they involve the users and their experience in designing process according to User-Centered Design (UCD) principles are considered. I gave the concepts for user interface, HCI, UCD, and usability issue and its relationship to designing process. Also I mentioned the general guidelines which are known as "Shneiderman's Eight Golden Rules of Interface Design" that should be considered. Moreover I explored that each platform nowadays has its own guidelines for best development of interaction process and that is why the applications of specific stage have the same layout. And I conclude that there is need for new methodologies and strategies of designing user interface that differs from methods used for developing traditional user interfaces due to enormous evolution of mobile devices and people's preference of such technology.
