HCI Principles - Perception

 
Perception
When it comes to designing a GUI (graphical user interface) perception is a very important factor. Perception is all about how someone using a GUI views and recognises certain aspects of the interface. When it comes to designing a GUI perception is involved in a manner of different things such as Positioning of windows, colours and the positions of icons on the desktop. All of these things will have an effect on what way a user of your interface will view and interact with it.
When someone is designing a Graphical User Interface they need to take into account the needs of the people that are going to be using it on a daily basis as the person who is designing it may not be associated with the same group of people that are going to be interacting with it. For example if I was designing a GUI I would have to take into consideration that people with disabilities may be using it therefore I would have to:
  • Use a fitting colour scheme for people with eyesight problems. (Change colour of background, text and Window colour)
  • Use a suitable size of icon for desktop shortcuts.
  • Never put text on a background that will clash as this could irritate the users eyes and make the text appear blurry.
