Human-Computer Interface is diverse in several fields. But the main focus is on the computer science area. Software developers are continuously developing new products that can be very helpful to people. Day by day new technologies are coming into the market, and most people are unaware of them. People use machines or computer technology in their daily life but they don’t even understand how that machine actually works, and what is the mathematical logic that is used in a programming language behind this. Understanding a machine-only programming language is not enough, human psychology and physiology are also much important to understand how a computer system works or responds. The main objective is to develop a user-centric system that can be used by commands and the system will do the work as per the user's need and understand how the system can be more useful and efficient and effective to make tasks easy for users.
