iTAP
Intelligent Keypad Text Entry API
When users are using features such as SMS (short message service), or "Text
Messaging", they can opt for a predictive text entry method from the handset. The J2ME
environment has the ability to use SMS in its API listing. The use of a predictive entry
method is a compelling feature to the MIDlet.
This API will enable a developer to access iTAP, Numeric, Symbol and Browse text entry
methods. With previous J2ME products, the only method available was the standard use
of TAP.
Predictive text entry allows a user to simply type in the letters of a word using only one
key press per letter, as apposed to the TAP method that can require as many as four or
more key presses. The use of the iTAP method can greatly decrease text-entry time. Its
use extends beyond SMS text messaging, but into other functions such as phonebook
entries.
The following J2ME text input components will support iTAP.
