Role of psychology in improving the longevity of user interaction with Interface design

User experience promotes Human Machine Interaction. It enables a user to interact with technology on daily basis. However, humans tend to change and adapt their behavioral pattern quite often, On account of doing so, we need to understand the connection and the psychological aspects of user to technology. This will enable user longevity and loyalty through the utility and ease of use. Hence, understanding mental models of user is a needful. There are many studies and theories which guarantee user engagements but they are all short lived. The psychological theories that have been proposed are quite few in numbers. The UX/UI designer tends to get in a state of uncertainty to which theory should be used for gaining longitudinal user relationship. In this paper, study of the standard and best psychological practices that will bring positive outputs in the field of UI/UX has been looked upon. Also, the various intrinsic and extrinsic factors which affect the user behavior has been analyzed. The study on the major triggers and the right way to approach user has been done. Moreover, understanding of the basic but rather important platforms where psychology can be put to use is been highlighted. The different psychological theories like Fog’s behavioral model, Hick’s Law and Color psychology where studied and its sequential and synchronized implementation on UI wireframes and lay outing was identified. A mixed study on samples explains the needs and requirement of psychological interpretation to get best UI outputs. The idea is to understand the psychology of both creator and end user so that a standard pathway can be streamlined.
