How does your iPod Touch work?

Answer 1

The iPod touch features a touch screen that allows users to access many different menus and features by simply touching or dragging items on the screen. The screen works in much the same way a touch pad on a laptop does. There are different types of sensors in use, but whichever type is used in the specific device can sense where the user touches on the screen, often through electrical impulses, and react appropriately. This is easier than using keys for a number of reasons. Users can select something they want simply by touching it, and can scroll through songs and menus with their finger. It makes the experience more interactive, and easier on those who are not used to how the various buttons on a traditional iPod work.

There are a few problems that occur with the iPod touch, just as with any other piece of electronic equipment you buy. The most obvious is scratching the screen. If something happens to your screen, you are limited on what you can do with your iPod touch. Since the menus and buttons are set up to be touch responsive, once the screen goes, so does the entire iPod touch. The iPod touch has been designed to prevent scratching, but it all comes down to who will be using the iPod touch and how roughly they treat it. The other factor in question is using touch instead of buttons. While some find these easier, others may have problems using the touch screen. Keyboards often are the hardest to use. Since the keys are visual, and you cannot feel the actual buttons, it can be hard to hit the right one to type quickly.
