HCI- Perception


 Perception- it is a way of conceiving things. Different people will differently understand and respond to what they see or feel via different senses.




 In terms of Graphical User Interface some of them may find it easy to understand all the icons and symbols on the computer screen. Others will have some serious problems for example because of the colors as they can be too bright and make eyes tired of looking at the screen or they can be matched to each other in a hard to read way. 
    Perception really matters and sometimes causes serious problems in HCI as its designers-(people that create GUI) can perceive things in a different way than their clients and actual users.
