iTap
iTap is a predictive text technology for mobile phones, developed by Motorola as a competitor to T9. It was designed as a replacement for the old letter mappings on phones to help in word entry on mobile phones. This allows an easier use of messaging and note-taking features. When you enter three or more characters in a row, your phone may guess the rest of the word. For example, if you enter prog, you might see: program. If you want a different word (such as progress), continue pressing keypad keys to enter the remaining characters.
Enter words
- Press keypad keys (one press per letter) to begin entering a word. As you type, your phone automatically shows additional letters that form a suggested combination.
- Scroll right to view other possible combinations, and highlight the combination you want.
- Press direction key "up" to enter the highlighted combination when it spells a word. A space is automatically inserted after the word.
If you enter a word your phone does not recognize, the phone stores it to use as one of your word options. When you fill memory space for unrecognized words, your phone deletes the oldest words to add new words.
Comparison with T9
Similar to T9, iTap is also able to complete words and phrases. iTap will guess the best match based upon a built in dictionary, including words sharing the typed prefix. This dictionary also contains phrases and commonly used sentences. This way the predictive guesses iTap offers are enhanced based upon context of the word that is being typed.
iTap typically uses a different user interface (UI) than T9 does. However, T9 provides an API that can be used to create a similar UI if phone manufacturers decide to do so. iTap provides suggestions for word completions after only one key press in all cases. However, T9 completes custom words after one key press and on most phones other words that users have entered previously can be retrieved after three key presses. T9 enables these UI decisions to be largely up to the phone manufacturer and so far none of them have chosen to mimic the UI of iTap with T9.
