Triangle Model Theory for Enhance the Usability by User Centered Design Process in Human Computer Interaction

Abstract

User Centered Design process or approach is one of the applicable methods that is using in Human Computer Interaction. This method is based on the relation of user requirement and satisfaction. Several methods are used for the development of user interface and interaction for a system. Human computer interaction tells us what should be the certain interaction and user interface that human can operate easily and efficiently. Any defective user interfaces or interaction methods are not acceptable and also harmful for human life. For developing Interaction methods or user interface are follows by some specific methods and processes. This research is based on the user centered design methods which is vastly uses in human computer interaction. The user centered design method has been developed in this research to overcome the limitations of the methodologies and the complexity of development process. A Triangle Theory Model has presented of the developed version of conventional user centered design methods. A briefly previous research works have been discussed in the field of user centered design methods.
