<p>A method for a human user to interactively enter an alphanumeric text message into a multiline display device (12) using a keypad (14) containing a number of keys. On one portion (22) of the display, the alphanumeric text message that the user is entering is displayed. On a second portion (23) of the display, a listing of subsets (24, 25) of alphanumeric symbols is shown, with each subset being mapped to a corresponding key on the keypad. The user selects the subset of alphanumeric symbols containing the one alphanumeric symbol to be entered into the alphanumeric text message and depresses the key that is mapped to the selected subset. In response to this action, the second portion of the display then changes to show the alphanumeric symbols contained in the selected subset, with each alphanumeric symbol mapped to a specific key on the keypad. The user then selects the desired alphanumeric symbol and depresses the proper key. In response to this activity, the selected alphanumeric symbol is displayed on the first portion of the multiline display device.</p> |
