System and method for dynamic key assignment in enhanced user interface

A method for data input on an intelligent device having a user interface, a display screen, and one or more keys, the user interface comprising a data entry field and a list of selectable characters displayed on the display screen, the method comprising the steps of:

• identifying a predefined list comprising a plurality of valid input items;
• parsing the valid input items in the predefined list to extract a set of valid characters associated with the first letter of each valid input item;
• determining a frequency associated with each valid character in the set of valid characters;
• displaying each valid character according to its frequency, such that characters with higher frequencies are selectable with fewer keystrokes than characters with lower frequencies;
• accepting a selected character;
• and
• displaying the selected character in the data entry field.

A method for dynamic key assignment on an intelligent device having a touch screen display screen and a user interface comprising a data entry field and a list of selectable characters, the method comprising the steps of:

• identifying a predefined list comprising a plurality of valid input items;
• parsing the valid input items in the predefined list to extract a set of valid characters associated with the first letter of each valid input item;
• determining a frequency associated with each valid character in the set of valid characters;
• displaying each valid character according to its frequency, such that the characters are presented on the touch screen display in a standard telephone keypad arrangement wherein characters with higher frequencies are selectable with fewer keystrokes than characters with lower frequencies;
• accepting a selected character;
• and
• displaying the selected character in the data entry field.
