ITap

From Wikipedia, the free encyclopedia

The correct title of this article is iTap. The initial letter is shown capitalized due to technical restrictions.

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.

One of the main differences between iTap and T9 is that iTap is able to complete words, phrases or even full sentences. T9 is unable to guess a word until the user has typed out a number of letters equal to the full word length. 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.
