1. The design of an application always requires metaphors in order to make the interface easy to use once the user lays hands on it. However, with the appearance of touch-based computers, the regular metaphors built around click and drag have gone through a shift of usage and implementation like you’ll see in the following examples:

Figure 1: Regular and touch screen metaphors As you can see on the above picture, both types of screens share common metaphors but how those metaphors are implemented and used on both screens differs. 2. Different kinds of interaction types and styles apply to both kinds of monitors and here are few: * App startup: Usually, double clicking an app on a regular screen used to help start it up but on a touch screen, everything is very intuitive so since the users already know they can interact with the screen, they can just tap the app and it starts right up. * Navigation: When an app is opened on a regular computer, like Microsoft word for instance, you go to the keyboard and start typing whatever you want and drag the mouse around to handle the buttons on the screen. On the other hand, on a touch screen computer, once you tap on a field where keyboard is needed, you have a virtual keyboard that pops on the screen allowing you to start typing. The mouse is also handled by touch.

...C h a p t e r 1 Prewriting GETTING STARTED (OR SOUP-CAN LABELS CAN BE FASCINATING) For many writers, getting started is the hardest part. You may have noticed that when it is time to begin a writing assignment, you suddenly develop an enormous desire to straighten your books, water your plants, or sharpen your pencils for the fifth time. If this situation sounds familiar, you may find it reassuring to know that many professionals undergo these same strange compulsions before they begin writing. Jean Kerr, author of Please Don’t Eat the Daisies, admits that she often finds herself in the kitchen reading soup-can labels—or anything—in order to prolong the moments before taking pen in hand. John C. Calhoun, vice president under Andrew Jackson, insisted he had to plow his fields before he could write, and Joseph Conrad, author of Lord Jim and other novels, is said to have cried on occasion from the sheer dread of sitting down to compose his stories. To spare you as much hand-wringing as possible, this chapter presents some practical suggestions on how to begin writing your short essay. Although all writers must find the methods that work best for them, you may find some of the following ideas helpful. But no matter how you actually begin putting words on paper, it is absolutely essential to maintain two basic ideas concerning your writing task. Before you write a single sentence, you should always remind yourself that 1. You have some valuable ideas to tell your reader,...
