Iphone : Using the “Multi-Touch” Interface

Mastering the Multi-Touch Interface

Virtually every cell phone known to mankind has a physical (typically plastic) dialing keypad, if not also a more complete QWERTY-style keyboard, to bang out e-mails and text messages. The iPhone dispenses with both. Apple is once again living up to an old company advertising slogan to ‘Think Different.”
Indeed, the iPhone removes the usual physical buttons in favor of a so-called mu/titouch display. It is the heart of many things you do on the iPhone. and the controls change depending on the task at hand.
Unlike other phones with touchscreens. don’t bother looking for a stylus. You are meant, instead — to lift another ancient ad slogan — to “let your fingers do the walking.”
The first thing to note is that there are actually three keyboard layouts: the alphabetical keyboard, the numeric and punctuation keyboard, and the more punctuation and symbols keyboard.

There are four keys that don’t actually type a character: the Shift. Toggle. Delete, and Return keys:

Toggle key: Switches between the different keyboard layouts.
Shift key: If you’re using the alphabetical keyboard, the Shift key switches between uppercase and lowercase letters. If you’re using either of the other two keyboards, pressing Shift switches to the other one.

To turn on Caps Lock and type in all caps, you first need to enable Caps Lock. You do that by tapping the Settings icon, then tapping General, and then tapping Keyboard. Tap the finable Caps Lock item to turn it on. Once the Caps Lock setting is enabled (it’s disabled by default), you double-tap the Shift key to turn on Caps Lock. (The Shift key turns blue whenever Caps Lock is on.) Tap the Shift key again to turn off Caps Lock. To disable Caps Lock completely, just reverse the process by turning off the Enable Caps Lock setting (tap Settings. General. Keyboard).

Delete key: Erases the character immediately to the left of the cursor.

If you hold down the Delete key for a few seconds, it begins erasing entire words rather than individual characters.
Return key: Moves the cursor to the beginning of the next line.

The incredible, intelligent, and Virtual iPhone keyboard
Before we consider how to actually use the keyboard, we’d like to share a bit of the philosophy behind its so-called intelligence. Knowing what makes this keyboard smart will help you make it even smarter when you use it:

It has a built-in English dictionary that even includes words from todays popular culture.
It adds your contacts to its dictionary automatically.
It uses complex analysis algorithms to predict the word you’re trying to type.
It suggests corrections as you type. It then offers you the suggested word |ust below the misspelled word. When you decline a suggestion and the word you typed is not in the iPhone dictionary, the iPhone will add that word to its dictionary and offer it as a suggestion if you mistype it in the future.
Remember to decline suggestions — doing so helps your intelligent keyboard become even smarter.

It reduces the number of mistakes you make as you type by Intelligently and dynamically resizing the touch zones for certain keys. You can’t see It. but it is increasing the zones for keys it predicts might come next and decreasing the zones for keys that are unlikely or impossible to come next.
