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
