Visual Ergonomics for Colorblindness: Providing Affordance in a Desktop Graphical User Interface.

Colorblindness is a condition in which the person affected is unable to identify a particular shade of color when it comes in contact with another shade of color in adverse lighting conditions, causing confusion in visual interfaces. Visual experiences on a computer interface consist of many data such as infographics, images, videos, graphs, presentation, maps, diagram, games, etc. Anything that has any kind of color-coded information is affected by color blindness. So, when a colorblind person is exposed to these colors and some conflicting colors are used in these elements, he/she may miss critical information. The graphical user interface (GUI) was introduced to quickly allow users to learn about the essential features of an operating system, thereby increasing productivity. With the evolution of GUI, software manufacturers started developing and including accessibility features in operating systems to cater to the extreme or benchmark users. However, there is still a lot of scope for improvement in the area of color blindness in a computer interface. This article intends to study the problems that occur/may occur for colorblind users with an objective to come up with better design solution to include colorblind users as mainstream user category in a computer interface and expand the user base of existing operating systems.
