advances in human-computer interface design which were designed to make it easier to accomplish things with a computer. Do you remember the first days of desktop computers? I do. I remember when I had to remember long strings of commands in order to do the simplest things like copy or format a disk or move to a new directory. I don't miss those days! Thank you, human-computer interface designers. (If you want to read about some of the pioneers of human-computer interface design, check out information about Douglas Englebart and Alan Kay.)
Human-Computer Interface Design seeks to discover the most efficient way to design understandable electronic messages [1, 2]. Research in this area is voluminous; a complete branch of computer science is devoted to this topic, with recommendations for the proper design of menus, icons, forms, as well as data display and entry screens. This browser you are using now is a result of interface design - the buttons and menus have been designed to make it easy for you to access the web. Some recommendations from this research are discussed below
