Yet you can find mouseover examples off the Internet too. Lots of programs featured changes by merely rolling over part of a screen. Many games, in particular used them. A mouseover can also be referred to as a GUI or graphical user interface. You’ll find computer games for children and adults, and even more business-oriented programs use mouseover or GUIs to develop more interesting effects without all that clicking or double clicking.
One very simple mouseover example, that you’ll see repeated again and again on Internet pages like Wikipedia and on wiseGEEK, is a slight change in color, and perhaps an underlining of certain words on text that is clickable (that might take you to another page or another site). As you’re reading a wiseGEEK page you’ll note if you use your mouse that simply moving the mouse over certain text will cause that text to become lighter-colored. Most computer users know this means they can click on the text to explore a link to elsewhere.
Mouseovers certainly don’t need to be quite that simple. WiseGEEK also uses mouseovers that bring up small windows, with advertisements. They don’t obscure your reading the text, and they can give you information about products or services available to you that are related to the subject you’re reading about.
